This guide helps you to determine and solve problems encountered when installing Ndless v3.1.
Student Software displays the error message “the handheld is not responding”
Don’t worry, this message will always appear at the end of the installation. The popup on the calculator side should confirm the success of the installation. No more steps are required and you can start using native programs. Close and reopen Student Software if you want to be able to continue to use it. If the error message still appears, try to reboot the computer.
Student Software displays the error message “The operating system file is corrupted or invalid. Please go to education.ti.com to get a new OS file.”
You are probably trying to install Ndless on OS v3.2 or higher. Ndless is currently not compatible with these versions. You must install OS v3.1, get it from tiplanet.org.
The TI-Nspire reboots when transferring ndless_installer-3.1.o.xxx
Make sure:
- OS v3.1.0.392 is installed on the calculator. You can check this in the Settings -> Status of the TI-Nspire. If not, upgrade the OS before installation.
- You are using the TI-Nspire Student Software, Teacher Software or TI-Nspire Computer Link Software v3.2 or higher to send the installer. Previous versions of Computer Link Software are not supported.
- You are using the latest version of Ndless, i.e. the one with the greatest revision number
- You have copied ndless_resources.tns in a top-level directory of the TI-Nspire called ndless (mind the case). The file must be transfered just under ndless, and not to a subdirectory.
ndless_installer-3.1.o.xxx is rejected when transferred
Make sure you are using the TI-Nspire Student Software to send the file ndless_installer-3.1.o.xxx.
If you are getting the error “Wrong handheld type for the OS being sent”, check that you are using the good ndless_installer-3.1.o.xxx for you device type:
- .tno: classic TI-Nspire
- .tnc: classic TI-Nspire CAS
- .tco: TI-Nspire CX/CX-M
- .tcc: TI-Nspire CX CAS/CX-M CAS
- .tmo: TI-Nspire CM-C
- .tmc: TI-Nspire CM-C CAS
The Student/Teacher Software displays during the installation the error “experienced a problem while communicating with the handheld. a retry may be successful.”
This error is expected. Make sure the installation confirmation is displayed on the device. Close the Student/Teacher Software and reopen it to be able to continue transfering files.
The TI-Nspire hangs at reboot time
If the TI-Nspire hangs at reboot time on this screen:
This can happen for example when a program not compatible with TI-Nspire CX is run on a CX.
To be able to boot again, you need to either:
- Unplug and replug the battery. This can be quite difficult to do on TI-Nspire CX, see this thread for some advice.
- On TI-Nspire CX, press the Reset button, and:
- Hold the the following keys at boot time: Esc+Menu+Minus
- This brings the diagnostics menu. Choose the option to run NAND tests.
- Exit the diags tool. The OS should now correctly boot .
The TI-Nspire falls into a reboot loop
- Reboot the TI-Nspire, by unplugging the USB cable, then removing and putting back a battery on classic TI-Nspire or by pressing the reset button on TI-Nspire CX.
- Enter the maintenance menu by turning it on while holding the following keys until half the progress bar:
- with the ClickPad keypad: Home+Enter+P then ON
- with the TouchPad keypad or the CX: Doc+Enter+EE then ON
- If the maintenance menu displays the message “Replace the battery and try again“, see below “The TI-Nspire CX falls into a reboot loop and ran out of battery”.
- Select ’2′ to uninstall the current OS. Reinstall it when asked to.
Next time make sure to never delete the file ndless_resources.tns as long as Ndless is installed. To uninstall Ndless, ndless_resources.tns should be opened first from the Documents screen, then deleted.
If the device still fails to boot, try to unplug and replug the battery (see The TI-Nspire hangs at reboot time above for hints with the CX).
The TI-Nspire CX falls into a reboot loop and ran out of battery
You then can’t open the maintenance menu as suggested above.
Press the Reset button, and:
- Hold the the following keys at boot time: Esc+Menu+Minus
- This brings the diagnostics menu. Choose the option to run the battery tests.
- Plug the TI-Nspire to a computer
- Wait for the battery to reach a level of 30%
- Exit the diags tool by pressing the Reset button at the back of the calculator (there’s not exit option in the menus)
- Now try to open the maintenance menu and follow the procedure above (“The TI-Nspire CX falls into a reboot loop”).
(Credits to TI-Planet.org for this procedure)
Running an executable from the documents screen displays “Sorry. Could not open document ‘xxx.tns’”
Ndless has not been correctly installed. Try to reinstall it.
I’m getting a “Wrong handheld type for the OS being sent” error using the TI-NspireLink software. Should I be using the TI Student CAS software instead? If so, how do I get to the “Install OS” button on the computer?
Never mind, figured it out.
How did you solve it? I’m getting the same problem.
Vincent2128, make sure you are:
* Using the right file for your device:
.tno: classic TI-Nspire
.tnc: classic TI-Nspire CAS
.tco: TI-Nspire CX
.tcc: TI-Nspire CX CAS
* If you are using TI-Nspire Computer Link Software, make sure to you v3.2. Previous versions are not supported.
The Nspire link software isn’t seeing my calculator any more since I installed Ndless.
Unplug the calculator, close the Student or Teacher Software and restart it. Then is everything fine?
i did these things but still i am getting the same error
Is Ndless installed on your calc?
Does rebooting the computer help in any way?
[...] Troubleshooting guide [...]
i downloaded ndless and i tried to play Ndoom
then my calculator said someting, it rebootes over and over and i cant stop it
Did you try the procedure “The TI-Nspire falls into a reboot loop” above? (sorry, this one and “The TI-Nspire hangs at reboot time” were mixed up, I have just fixed this).
I would but my calculator ran out of battery and it wont charge
please help
First plug in the USB cable. Then run the maintenance menu as explained above, and keep the device charging there for a while if needed. Then follow the last steps of the procedure.
just tried it what you said didn’t work
Is this issue similar to yours? http://www.omnimaga.org/index.php?topic=12602.0
Can you let the battery charge in the maintenance menu on the message “”Please replace the battery and try again. Press any button to power off.”?
I’ve added a troubleshooting section for this issue, see “The TI-Nspire CX falls into a reboot loop and ran out of battery”.
Hello. I still have the same problem as before. “I have upgraded my CX CAS to version 3.1.0.392, and selected Install OS in the computer linking software and selected the “ndless_installer-3.1.0.tcc” file (all the others were greyed out) and tried to install. It game me this error: Wrong handheld type for the OS being sent. I have done this successfully on my Touchpad calculator with the same OS, but it doesn’t seem to work. Can you help?”
Ben, can you make sure you are using Student or Teacher Software? “TI-Nspire Computer Link” doesn’t support TI-NSpire CX files .tcc or .tco.
My TI falls into a reboot loop and ran out of battery, but when i do the esc+menu+minus nothing happend what can i do im desperate
PLZ!!! can you make a video on how to do this? Do I NEED a TI-Nspire CX CAS because i just have a regular CX? When i try to open ANY of the software on my TI-Nspire CX CAS student software, it says it is not compatible with the type of software. How do you create a directory on the TI-Nspire and how do you get the stupid Press-to-test mode off? HALP
The regular CX is also supported.
To create a new folder, read the “Creating folders” section p.44 of http://education.ti.com/downloads/guidebooks/ti-nspire3/TI-Nspire_CX_Handheld_GettingStarted_EN.pdf
Make sure to select the right ‘ndless_installer’ file for your TI-Nspire model as explained above (“ndless_installer-3.1.o.xxx is rejected when transferred”).
To know more about the Press-to-Test mode, read the TI-Nspire Press-to-Test Guidebook here: http://education.ti.com/calculators/downloads/US/Guidebooks/Search/Results?cp=6001
You can also get general help on the TI-Nspire on the community forum http://www.omnimaga.org/ , TI’s official knowledge base ( http://epsstore.ti.com/OA_HTML/cskmbasicsrch.jsp ) or by contacting directly TI-Cares.
to get off of press to test mode i re-installed os, it worked
When I click on the ndless_installer-3.1.0.tcc ( i’m on a nspire cx cas) it gives me error:-1, that says that he file conversion was not sucessful. I serached for a fix but i didn’t found on. I’m have the version 3.1.0.392
You should drag and drop the file within Student/Teacher Software. Follow this tutorial with screenshots for more details: http://tiplanet.org/forum/viewtopic.php?f=17&t=8677
I tried on my Clickpad non-CAS 3.1
Now, it’s stuck in the Documents folder with My Documents selected and it won’t go away, even with the calculator batteries removed.
Random freezes have been seen on Clickpad models. Make sure to unplug the calculator from the computer when removing the batteries.
When transferring the .tcc installer for my calculator, halfway through a message pops up saying error, the handheld is not responding. Please help?
As long a the device displays a popup confirming the installation, everything is alright. The error on the computer side is normal, just close and reopen Student Software.
When I transfer the .tcc installer to my cx, the computer displays a message saying “experienced a problem while communicating with the handheld. a retry may be successful.” then reboots the calculator halfway through installing. Help?
So your TI-Nspire is a CX CAS since your are sending the .tcc file? Did you make sure OS v3.1 is installed on your calculator? Has ndless_resources.tns correctly been copied to a directory called ‘ndless’ under ‘My documents’?
Oh thanks, so the OS was the problem. I thought the Handheld OS would have came with the Student software when I downloaded the software.
Hi, my ti-nspire cx still won’t accept my ndless file. i keep getting “experienced a problem while communicating with the handheld. a retry may be successful.” even after checking that OS v3.1 was installed. What do i do?
Walter, this error is expected at installation time. Make sure the installation confirmation is displayed on the device. Close the Student/Teacher Software and reopen it to be able to continue transfering files after the installation.
but i don’t get any “installation confirmation” on my device :(
The installation of Ndless implies two steps:
- Transfering ndless_resources.tns to a folder named “ndless” under “My Documents”, created on the device
- Transfering ndless_installer-3.1.0.txx as an OS update, where the .txx extension matches your device model.
At which of these two steps does the transfer fail?
also, i keep getting a “the handheld is not responding” message. what do i do???
@ExtendeD the second step.
Are you transfering the .tco file, since your device is a non-CAS CX? What does the device display on its screen when installing?
(solved: Walter’s ndless_resources.tns wasn’t *directly* under the directory “ndless”)
now it’s starting to display “the handheld is not responding” and mine is TI-nspire CX only
My friends calculator has the same problem as rajeeps. It ran out of battery, and now i can’t get the diagnostics menu up. Please help, it’s a TI-Nspire cas cx.
Could you please try the different suggestions of this thread? http://www.omnimaga.org/index.php?topic=12602.0
If none works, your friend will have to borrow a charged battery to someone and reinstall the OS. See this thread on how to do this: http://www.omnimaga.org/index.php?topic=12337.msg225964#msg225964
None of the options at the first site worked, so im gonna put my calcs battery into his. Thx for the references. Ill reply if any work, so that others could try it. Thx again
sorry for late reply. yes it worked by putting battery into the other calculator, and now my friends is back to normal. Thx so much!!
My nspire cx cas says it installed correctly, but it says the ndless.cfg.tns file format is not supported.
Are you trying to open ndless.cfg.tns? You don’t have to.
I was reading the readme for a program that required ndless. It was not very clear that ndless.cfg had to be changed from the computer. I was able to sort that out. However, I fell into an endless reboot cycle and i had to uninstall the os. Now ndless will not install. I have the cfg and resources file in the ndless folder on my cx cas, and I am using the installer.tcc. I have the correct os, however, when I try to install ndless, it comes up the with the error message saying the communication stopped, and my calculator reboots, but it does not come up the message saying ndless has been installed. I have confirmed that it is not installed by trying to open resources on my calculator. It does not give me the option to uninstall ndless. I cannot figure out why it will not install.
Did you make sure to copy ndless_resources.tns exactly as on the first screenshot of this page? (same folder name, same file name, right under My Documents)
Problem solved with Matt. For those with the same issue, please make sure you are using the latest version of Ndless (the one with the greatest revision number).
Yes.
I did all the “The TI-Nspire CX falls into a reboot loop and ran out of battery”, I uninstall the OS and everything but when it shows “operationg system not found. Istall OS now” how do I do that if my calculator doesn’t appear in the student software. Help me please
never mind
How do i exit the diag tool, i mean which buttons should i press? Because I’ve charged my ti-nspire CX CAS with the “Battery Pack Charging and now i don’t get back to the Restart Loop, so that I can’t open the maintenance menu? :(
Just press the reset button under the CX to exit from the diags menu. Then open the maintenance menu as described in “The TI-Nspire falls into a reboot loop”.
Ok so now I’ve uninstalled the OS, but when I started my CAS again it booted a bit normal but when it says: “Operating System not found. Install OS now”. the screen freezes.
Now I’ve unplugged the batterie but that didnt help and it’s the same problem: The screen just freezes and it say: “Operating System not found. Install OS now”.
What can i do to solve this problem?
For those with the same problem: connect the calculator and send a fresh OS from TI’s web site with Student Software.
Nevermind Solved it by myself :)
Hello. Whenever I try to open a game file with .gb.tns on my TI-Nspire CX CAS a message appears, saying: This document format is not supported.
I had gotten everything by following a YouTube video, and I’m positive I did exactly what he did. All the comments say their’s worked fine. When I asked him about the error, he said he didn’t know what to do. Someone else replied that you need to unzip the files, but I have already done that. Any suggestions?
Nevermind, I got it to work :)
For people with a similar issue: make sure to send ndless.cfg.tns to the calculator to be able to open files with custom extensions such as “.gb”.
I’m getting the “document format not supported” error as well. It won’t even open the sample file- particles. And where is ndless.cfg.tns? I can’t find it anywhere in the file.
Mitchell, did you get the confirmation popup on the calculator when installing Ndless? If not Ndless is not correctly installed.
ndless.cfg.tns is next to the other Ndless files in the calcbin/ directory of the Ndless zip archive, and must be sent along with ndless_resources.tns.
I did get the confirmation pop-up. Also, I realized I wasn’t using the latest release of ndless, so I got that and found ndless.cfg.tns.
Still no luck. I receive the same error.
Did you follow again the whole installation procedure with the latest version of Ndless? You should get another popup about Ndless being updated.
After attempting to install it several times from release 623, I fell back to release 620. That worked. 623 just kept reinstalling the 3.1 OS. Thanks!
I just had a quick question. 3 of my friends had their tinspire fall into a reboot loop, similar to last time. I fixed it, but what is the cause of this? I’m starting to think that they might be doing this on purpose
The reboot loop is provoked by the deletion of ndless_resources.tns. Preventing it is unfortunately not easy because of some constraints.
ah ok. The other day, my friend said that when he transferred a gbc rom to his calc, it kept rebooting. Now even i cant fix it! ive tried removing battery, Complete format, and Os reinstallation. Is it possible that it could have happened because of the rom, or is that a lie? And what to do to fix it? Sorry for asking once again.
The reboot loop could not be caused by the rom file itself.
You could also try to:
- run the NAND tests from the diags menu
- unplug the battery if it still fails to boot
The two options are described in the article above. Tell me if you’re still stuck after this.
I have a folder with ndless resources in it and i keep trying to transfer the tco file to my cx and it keeps saying my device is busy or there was an error. No message has shown up on my calculator either.
Jake, did you make sure to drop ndless_resources.tns in a directory called ‘ndless’ as shown on the screenshot above? Does your calculator reboot when the .tco is transferred?
I have deleted all the files in my calculator, but it worked until it got out of batterie, now when i connect it to the pc it keeps in a reboot loop
Can you help me plz?
Dis you try to follow the procedure “the TI-Nspire CX falls into a reboot loop and ran out of battery” above? Which step goes wrong for you?
Thank you, problem solved
I was not doing it right
Thanks for the guide! I was using ndless so I could run an emulater on my calculator (Ti-nspire Cas touchpad) and the loop glitch happened to my friend. I brought it home and read this guide and fixed it, and then the same thing happened to me! Is there anyway of running it without having that glitch happen?
Michael, the reboot loop is caused by ndless_resources.tns being deleted. This file should never be deleted while Ndless is installed.
To uninstall Ndless, ndless_resources.tns should be open first from the Documents screen, then deleted.
I didn’t touch the resources file, and I didn’t change the file path or move it and I had the exact configuration specified and it was working until it happened…
Strange. Tell me if you have more clues on it.
I’ve read your guide, and yet, I’m still having problems. I try to transfer ndless_installer-3.1.o.tco, and it still says “Wrong Handheld type for the OS being used” while I am using the correct type, a TI-nspire CX. Not only that, but when I transfer ndless.resources.tns, it says it’s not supported. If you can help me, I would really appreciate it.
Janelle:
- Did you make sure to use “Student Software” and not “Computer Link” software on the computer side?
- Is your CX a *non* CAS CX, since your are transferring the .tco file and not the .tcc file?
You’ll also find screenshots on how to transfer the files to the calculator here: http://tiplanet.org/forum/viewtopic.php?f=17&t=8677
I used Student Software but when I tried to transfer ndless_installer-3.1.0.tco and ndless.resources.tns, it says the file format is not supported.
I am also using a TI-Nspire CX, not TI-Nspire CX CAS
The .tns should at least be transferred without problem, there’s something wrong in how you’re trying to send the file.
Are you drag n’ dropping it to the “connected units” window of Student Software?
hey, i´m using a cx cas and a student software. trying to put ndless-ressources on my calculator doesn´t work. there is an error saying “fille is not supported”. can you help me?
Are you using Student Software? Are you drag n’ dropping the file to the “connected units” window? Have you had a look at the TI-Planet’s tutorial with screenshots? http://tiplanet.org/forum/viewtopic.php?f=17&t=8677
HELP. I am using TI-Nspire CX CAS and recently both my calculators with ndless (the other calc is a TI Nspire Touchpad) wont come out of a reboot loop. I i have done the complete reformat after everything else failed, and now I can connect to it using the computer link software ver 1.4. But now i can’t install the os from TI’s site. The filename is: “TI-NspireCXCAS-3.1.0.392.tcc”
It keeps telling me “Wrong handheld type for the OS being sent.”
WHAT DO I DO??? I really need the calculator for my maths classes.
Fixed with Xeni. For those with the same problem: make sure to use Student or Teacher Software. TI’s old Computer Link cannot send OS updates to the CX.
Hey ExtendeD
Maybe you should change the User Guide because of this. In the user guide, in the requirements it says “Any linking program such as TI-Nspire Student Software”.
Xeni
Sure, thanks.
HELP I did everything right but the computer kept on saying “the handheld is not responding” I tried closing the TI-Nspire Student Software already but the same thing came up again What should I do?
Max, the “not responding” message on the computer side is OK. Just make sure the installation confirmation popup appears on the calculator side.
If closing and reopening Student Software is not enough, try rebooting your computer.
Hi I installed ndless correctly on my Nspire cx (I know because I was able to play Pokemon for a while on my calculator) however, after turning it on one day I am unable to open the ndless files. Both the gbc emulator and the ndless resources. It says “This document format is not supported [filename].tns” I don’t recall making any changes to my calculator during that time.
Nath, Ndless has most probably been uninstalled from your calculator by opening ndless_resources.tns.
Anyway you’ll have to reinstall it with a computer and the installation procedure.
Yes it works now thanks so much ExtendeD (:
Okay, here is my issue… I have upgraded my TI-nspire Touchpad Calculator to OS v3.1.0.392 (verified on my calculator at the Status screen), I have downloaded and opened Student Software and successfully transfered the ndless_resources and the ndless.cfg files onto my calculator into the ‘ndless’ folder that I created. However, when I got to transferring the ndless_installer-.tno, I received the confirmation on my calculator, but I received an error on my computer screen stating that the handheld was not responding. Following the troubleshooting guide, I simply closed Student Software, reopened it, and tried again. This time my calculator displayed the confirmation message along with a notice that the calculator would have to reboot. This problem leaves the installer unable to be transferred into the ‘ndless’ folder. This issue is driving me crazy so if you could please assist me with my update I would greatly appreciate it!
Matt, the popup on the TI-Nspire side confirms the installation. Don’t worry about the “not responding” message on the computer side which always shows up at the end of the installation. You should now be able to use native programs.
The installer is a special file which won’t appear in the Documents directory of the TI-Nspire.
Sorry if this wasn’t clear.
Thank you for all of your help!
everytime i try to ‘send os’ a box that says ‘wrong handheld type’ always pop up. help please :)
mich:
- Did you make sure to use Student Software (and not the old Link Software)?
- Does the file extension of ndless_installer matches the calculator model you have?
.tno: classic TI-Nspire
.tnc: classic TI-Nspire CAS
.tco: TI-Nspire CX
.tcc: TI-Nspire CX CAS
Hi! I desperately need help. I will be needing my TI-Nspire CX CAS calculator for a math exam next week. The problem is that it suddenly stopped working. I thought it was out of battery, but when I plug it in to charge, nothing happens. The screen remains dark, the calculator doesn’t turn on. Any ideas as of what this could be and what I could do to fix it? I’m certain that the calculator was not damaged in any way. It just stopped functioning.
mia, I’m not sure this is related to Ndless. This could be an hardware issue. Also make sure to let it charge long enough. You may try to get some help on omnimaga.org’s forum.
mia, if your TI-Nspire still doesn’t want to startup, try to unplug and plug back the battery. This is not an easy operation, you can get some advice in this thread: http://www.omnimaga.org/index.php?topic=12337.msg225964#msg225964
I had the same problem but my screen is white, no dark. Could you help me please
help nothing happend when i try with the esc+menu+minuss
minus is the – key right?
Yes Mariela. Make sure to keep the 3 keys pressed simultaneously during the whole boot sequence.
I can’t access at the diagnostic menu. I keep pressing esc+menu+minus but it doesn’t work. It keeps rebooting. Help
Max, as for Mariela, did you make sure to keep the 3 keys pressed *simultaneously* during the *whole* boot sequence? Let it reboot multiple times while keeping the keys pressed if needed.
When will os 3.2 support be added?
Upgrading Ndless to a new OS version usually requires a consequent amount of work because of the stupid and useless fight TI is carrying on.
OS v3.2 appears to bring several regressions that TI may (and ought to) quickly fix. This would make any investment in a v3.2 update of Ndless useless.
For this reason, and because downgrading to v3.1 is fortunately not yet blocked, no support for v3.2 is planned for the moment. Sorry for the inconvenience it may cause, but TI’s position against Ndless make decisions more difficult.
my calculator says that the file may be corrupt or broken and will never install the file is a cas touchpad
“The operating system file is corrupt or invalid.
Please go to education.ti.com to get a new OS file.”
thats the exact error
Matthew, did you make sure to install Ndless on OS v3.1? Ndless doesn’t offer OS v3.2 compatibility yet.
OS v3.1 can be downloaded from here: http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
that might be the problem… i upgraded to 3.2… so… there will be ndless support for that version soon?
My cx cas shows a attention icon when i want to start
and it is hanging up.
i tried all this to solve the Problem:
1. [doc][EE][Enter]+[on]
2. removing accu pack for 5s and press [doc][EE][Enter]+[on]
3. RESET button
Sorry for the late response.
Does the icon appear when the progress bar is half filled or at the beginning of the progress bar?
Is the calculator detected my Computer Link or Student Software? If it is did you try to resend a fresh OS copy to it?
No the computer can`t detect the calculater.
and the icon appear at the beginning of the progress bar.
all what i can do is open the diagnose menu.
It sais “Wrong handheld type for the OS being sent” all time, doesn’t matter wich installer i use.
Oh and yes i got the OS-version 3.1.0.392 and the ndless beta 3.1
Nico, did you make sure to use Student Software to send the installer?
ExtendeD,
I have a couple of questions regarding ndless running nclock. 1.) Does nclock running in the background have a significant impact on battery consumption? Have you run any tests? 2.) Does nclock prevent the Nspire from powering down,or does ndless prevent the Nspire from powering down normally(e.g., calculator inactivity after a certain time has elapsed)? I ask because none of my Nspires (CX-CAS, CX, CAS Touch-Pad) will power-off after a period of inactivity running ndless and nclock.
Thanks
Jon
Jon, I don’t know exactly how nClock works, I’m forwarding your questions to it’s author.
Regarding Ndless interfering with the automatic power down: I haven’t got any report related to Ndless itself. You may want to try removing nClock and see if the issue disappear.
I appreciate your prompt response. I tried your suggestion of removing Nclock – same results, no power off. I then removed Ndless, and the Nspire CX powered off normally. I re-installed Ndless (r.685), and again, it will not power-off normally. This is not a significant problem for me, really. I sincerely appreciate your efforts in expanding the potential of the Nspire to the community.
On a related note: do you think it will be possible to port a
CX CAS O/S to a non-CAS CX?
Thanks
Jon
I’ll investigate, sorry for the inconvenience.
For your last question: OSLauncher is designed to run any TI-Nspire OS, but to what I know running a CAS v3.1 OS on a non-CAS hardware is currently not supported, or not stable enough: http://www.omnimaga.org/index.php?topic=12866.0
lorenz, could you please try to hold the the following keys at boot time: Esc+Menu+Minus
This will bring the diagnostics menu. Choose the option to run NAND tests, then exit the diags tool. Try to boot the calculator again and see if the computer recognize the device to let you install a new OS, or at least bring the maintenance menu with the Doc+Enter+EE combo.
Okay i launched the test and it `pass`… so i tried to boot it nothing changed,
i tried to launch the menu for deleting the OS nothing happened (display the same like in the Video) … and my computer can´t find the handheld
I think the last programm i launched was the “theme maker”
Lorentz, your boot2 appears to have been corrupted. Reflashing it may be the only option for you. Please refer to Xavier’s e-mail for advice on how to fix this.
mine says the os is invalid or corrrupt, what am i doing wrong?
You are probably trying to install Ndless on OS v3.2. This version is currently not supported, you have to downgrade. Please refer to the second toubleshooting entry above.
Every time I try to move ndless_resources.tns to the calculator under the ndless folder in my library, it shows a “cannot do” circle with a line through it. My calculator is in 3.1.xxx and my my software is in 3.2.xxx. I have ndless version 3.1. I am using the TI Nspire CX. It seems to work for everyone else I watch but they’re all using the CAS. Are there any CX differences, and if so maybe a tutorial? Help would be much appreciated!
Ryan, does the windows you see in Student Software look like these one? http://tiplanet.org/forum/viewtopic.php?f=17&t=8677
I actually got it to work using the software’s own browser by putting the resources file on it’s own under my documents. From there it allowed me to copy the file to my calculator. Thanks for the timely response though!
I downloaded the ndless file but ndless_recource wont go into the ndless folder i made when i click and drag nothing happens. any help??
Javier, did you make sure to drag the file to the “connected units” window of Student Software?
And as described by Ryan above, make sure to drag the file from the software’s own file browser and not the Windows or Mac file browser.
I have the nspire cx and i have installed the recources but when i try to install the Tco it says on the calc endless sucsessfully installed rebooting now and the loading bar on the computer stops. If i press ok then my nspire reboots therefore disconnecting it from loading the Tco file.
NAte, the connection error on the computer side is expected and not a problem.
The popup on the calculator side tells you than Ndless has been successfully updated.
But the Tco does not appear in the document folder on my calculator. I dont get an error on the computer the loading bar just stops loading.
Don’t worry, the .tco file is considered as an OS image by Student Software, and won’t appear in the Documents screen.
What’s happening on the computer-side doesn’t matter much. If you get the installation sucess popup on the TI-Nspire side then everything is OK for you.
thanks i didn’t know what you meant by its own browser so i tried dragging from Winrar and it worked thanks allot.
I have cx cas. The battery is flat, but it wont charge. The charge line gets halfway across the screen, then just starts again. Have left it charging overnight but was still doing the same thing in the morning. Have tried reconnecting battery, rebooting and everything else advised here without success. Please help…
Sorry, should have said the LOADING bar when you first turn it on gets halfway across the screen then just restarts..
Did you follow every instruction of the section “The TI-Nspire CX falls into a reboot loop and ran out of battery” above?
First tried the reboot – with the TouchPad keypad or the CX: Doc+Enter+EE then ON. Nothing happens at all. Have unplugged and replugged the battery.
Then tried – Esc+Menu+Minus with the calculator attached to the computer. I got the menu – NSC MP V2(2011/03/24) Diag, it fails 1. LCD, but there is no option given to run battery tests and it is not possible to move down through the options. Prior to this problem I had not done anything to the OS or files or done (or tried to do) anything clever. I just use it! Thanks
James, the diags menu you are looking for is “5) Manual Test > Battery Test > Battery Pack Charging”. (see here for more details in French http://tiplanet.org/forum/viewtopic.php?t=9262&p=124220#p124214 ). You should let your calculator charge from here.
You most probably have deleted the file ndless_resources.tns, and your calculator ran out of battery.
Ok, I am there – Thank you so much. Once it is charged will it work as before? I didnt deliberatly delete any file, how can I stop this happening again?
Once charged you must open the maintenance menu, remove the OS and reinstall the OS as described in the section above.
Maybe ndless_resources.tns was deleted because of a miuse of Nover which corrupted the filesystem? Else I can’t really see how it could happen.
Hi! I followed the tutorial step by step and checked several times that I have the correct OS but when i try to install ndless it just ends up installing a newer OS.
I have a nspire cx cas btw
Quick question: I am following all the steps and I have tried multiple times with different OS’. After many tries, however, I keep coming up with a message on the calculator saying that the .tns file extension isn’t supported. I have spent over 2 hours on this, and still no luck. Please Help!!
Extra Note: I have a Ti-Nspire classic (Non-CAS)
Right now I am using the Ti-Nspire CAS Student Software and Ti-Nspire CX CAS, os 3.2. I can’t figure out how to downgrade my os to 3.1 for both the computer software and calculator. Please Help.
when dragging the ndless_resources file a message pops up saying folder not found. i’ve made multiple folders and gone to the root of the system.
How do i exit the diags tool?
Sorry I forgot to mention that there’s no menu to exit the diags tool. You must press the reset button at the back of the calculator.
my ti nspire cx says operating system not found. install os now and it doesnt connect to the student software and i tried running nand tests and i did all the options on the maintanence tool
James,
- Do you at least hear Windows “dum-dee” sound effect when you plug in your USB cable when the message “operating system not found” is displayed on the calculator?
- Do you mean that in Student Software the calculator is not advertised anymore in the connected unit window?
yes to both, it makes the dum dee when i plug it in and the dee dum when i unplug it and it doesnt show up in the connected unit wndow
James, could you please try the following options:
1) a) Enter the maintenance menu by turning the CX on while holding the following keys until half the progress bar: Doc+Enter+EE then ON
b) Choose a complete format
c) Retry to connect it after the reboot
2) Install Computer Link 3.2 and see if the calculator shows up with it: http://education.ti.com/calculators/downloads/US/Software/Detail?id=6772
3) Install Student Software or Computer Link v3.2 on another computer and see if the calculator shows up
Sorry for the trouble, tell me how it goes after this.
it shows up in the computer link software
Good to hear this a problem on the computer-side . Maybe you just have to reinstall Student Software to fix it.
Every time I try to run a program that uses ndless, the calculator crashes and reboots, then goes back to the main menu, but it doesn’t ask for info like languages. I’m using the latest ndless variant and 3.1 os, and I’ve re-installed ndless twice, each time removing the old installation. The normal lua and basic apps work, but not the good ones that need ndless (the reason I bought the calculator, other than my future academics) If you know what I did wrong and how to fix it, please let me know. I need to show my friends something and I want to be able to use this like it was supposed to be (for my purposes) It’s a TI-Nspire CX. (Non-cas)
evanzolman, can you please give a link to the program you are trying to run so that I can have a look on my side?
Can you also confirm that the version of Ndless you have installed on your calculator is ndless-v3.1-beta-r685?
Hi everyone. First of all, thank you very much for the work are you doing.
Well, my problem is similar to the one that commented “evanzolman”, just before me. I’ve installed ndless 3 on my nspire CAS (non color) and when I try to run the program gpsp_launcher (gba emulator) the calculator reboots. This issue happened to me also with a “snake game” file. I’ve done the installation process many times, following each step and being sure I have the correct SO, Computer Link version and latest ndless 3.1 version, but with the same result. Could you help me, please?
Thanks
Albert, are you using both Ndless v3.1 r685 and gpSP-Nspire alpha 11? ( http://www.omnimaga.org/index.php?topic=14079.0 )
Yes!
Then something may not be correctly emulated with the game you are trying to run with gpSP-Nspire. You can try to report the issue to calc84maniac on the thread on Omnimaga, but since the emulator follows a best-effort policy he probably won’t do much about it, sorry…
i’m not able to drag any files from my computer to the calculator on CAS student software whenever i try it the file doesnt show up
Eli, you must make sure that you are drag n’ dropping the file:
- from Student Software internal file browser and *not* from WIndows or Mac standard file browser
- to Student Software’s “connected units” window
Please have a look at TI-Planet’s tutorial that may give you hints with its screenshots: http://tiplanet.org/forum/viewtopic.php?f=17&t=8677
What is the latest version of ndless?
Kenneth, the most recent version of Ndless is the one with the highest number. Today it’s ndless-v3.1-beta-r685.
i bougth a USB-TTL adapter to refreshing boot2 on my cx cas and i contacted it but my computer can´t find the handheld
Lorenz, I suppose you’re trying to fix your boot2 which is apparently corrupted. Did you follow this tutorial? http://tiplanet.org/modules/archives/downloads/repair301.pdf (in French, you have to Google-translate it).
I’m having a problem with my software,ndless installed perfectly,thank you! But now when i plug in my calc to the computer and open the software i dont see my calc pop up it says “connectivity with TI-Nspire handhelds is unavailable”, its a ti-nspire cx.
Corey, Ndless should not interfer with the connectivity with the computer.
Does closing and reopening Student Software fixes the problem?
Else does rebooting the calculator or uninstalling Ndless fix it?
Can you help me? My TI-nspire CAS hasn’t been used for about 5 months. Today, I put the new batery and press On but the calculator only run for 2 second and after that I cannot start my calculator again. Please give me some advices, thank you!!!
Lewis, can you try to follow the section “The TI-Nspire CX falls into a reboot loop and ran out of battery” above?
On my TI-nspire I can install everything but I try to send the text with the notepad and appear this document format isn´t supported. like you said here “File association
(since v3.1 r538) You can directly run files with extensions from the OS native document browser, for example to open .png files with mViewer or .nes files with NESpire (demo for NDoom).
Ndless comes with default associations for several TI-Nspire programs. These associations are configured in ndless.cfg.tns. You can edit this file on a computer with a text editor my renaming it to ndless.cfg.txt. To add a custom file assocation for a program (for example to associate .txt files with a program named textviewer.tns), add the following line:
ext.txt=textviewer.tns
Rename the file back to ndless.cfg.tns, and send it to the ‘ndless/‘ directory of the TI-Nspire.
When a document named .txt.tns is open from the OS document browser (and displayed as <document-name.txt on the TI-Nspire) a program named “textviewer.tns” will be searched in all document folders and used to open the .txt file. Note that programs must explicitely support file association, ask their authors for it."
but it does always the same. I just want to read text files on my inspire.
if you could help I would thank you a lot
FZ, “ext.txt=textviewer.tns” is just an example, there’s no such “textviewer.tns”.
To read plain text files on your TI-Nspire, you may try nTxt: http://www.omnimaga.org/index.php?topic=14593.0 . But I’m not sure file association has been implemented for this program.
Hi I downloaded it in a new odrner but my handheld restarts alltime. I used the steps but nothing happend. HELP!!
Jonas, do you mean that your handheld restarts at installation time? Did you make sure to downgrade to OS 3.1, available here? http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
Hello. First of all, thanks for ndless, it has been great to use. I have however run into a problem that I can’t help but think is due to this program.
Earlier today, when I rebooted out of press-to-test mode, my calculator just randomly started not recognizing its internal battery. When I run the diagnostics screen, it recognizes that it is connected to an external power source, and is receiving an input voltage, but there is no charging voltage, or charging percentage info.
Do you have ANY suggestions? I need my calculator for exams next week!
Thank you in advance for any help.
Justin, to understand if it’s a software issue caused by Ndless or an hardware failure, could you try to uninstall Ndless by running “ndless_resources” and see if it fixes anything?
Also what do you mean by “not recognizing its internal battery”?
Sorry for the trouble, I’ll try to help you as much as I can before your exam.
Hey ExtendeD,
Thank you very much for the quick reply, and don’t worry, it’s not your fault!
I uninstalled Ndless by running ndless_resources – no change in the battery problem. I also removed nover (not that I was able to run it anyway with Ndless removed…)
When I plug the calculator into the wall or into my computer, it says that it is charging, and that the internal battery is at 0%. When I unplug it, it says that the battery is at ‘critical level’ and (strangely) it is running on external power (even though it is not). I have a feeling that it is a software problem (corrupt OS?) as it would seem very strange to me to just suddenly have a hardware problem like this. Still, I really don’t know. I’ve tried to completely reset the calculator by reinstalling the OS (3.1), but the student software won’t let me because the calculator (apparently) doesn’t have enough battery.
The strange this is that, after leaving it plugged into the wall for all of last night, it still hasn’t died, even though since I unplugged it it’s been at ‘critical battery’.
Thanks in advance for any ideas!
J
Hey ExtendeD.
So now my calculator has completely stopped working – when I tried to put it in press to test mode, it now has started saying that I need to install an os – but I can’t because the battery is too low…
Justin, since uninstalling Ndless doesn’t fix the problem (Ndless’s uninstallation always leaves the OS to original state), and because diags software which performs raw hardware checks reports wrong info, this is most probably an hardware failure – hopefully only the battery is involved.
You could check this by replacing your battery with someone else’s and doing the same tests again. Removing yours is not easy, you may find some advice here: http://www.omnimaga.org/index.php?topic=12337.msg225964#msg225964 . Make sure not to break the wires.
But you’d better replace your TI-Nspire if it’s still under warranty.
I hope you’ll be able to find someone to lend you his TI-Nspire for this week’s exam.
Hey ExtendeD,
Thanks for your responses. I tried using a friend’s battery to charge the calculator, with no success – it ‘sees’ that as empty as well, so I think it’s the calculator itself that is having problems. I am in touch with TI and they have connected me with the Canadian TI provider, so if all goes well I should be able to get a replacement calculator. Too bad that all this happened!
In any case, thank you for your help, and thanks for Ndless – it was awesome while working!
J
the gbc4nspire says no roms loaded or something…
how do i fix it
shamra, for questions specifically on gbc4nspire, you’d better asked on gbc4nspire’s thread on Omnimaga.org: http://www.omnimaga.org/index.php?topic=1243.0
Please could u tell me how display with keypad: Home+Enter+P then ON
I tried but it reboots again and again please tell me how to do it.
Regard,
Ahmed
Ahmed, make sure to keep the Home, Enter and P keys pressed simultaneously during the whole boot sequence. ON should be the last key pressed to turn on the calculator.
This combo is for Clickpad calculators only. If you have a CX, Replace the P key by the EE key.
Thank you :D
I love ndless and my gameboy advance games.
My cx cas fell into a reboot loop w/o power and this troubleshooting guide worked fantastically.
Thank you for making my calculator amazing!
hey I followed the “The TI-Nspire CX falls into a reboot loop and ran out of battery” portion and i got to the “Battery Pack Charging” screen, but under “Charging Voltage/Capacity” there is a blank next to the %. Something like “3.354V / %” what can i do?
oh nevermind! after like 10 minutes it started to charge. thank you for the instructions! i was so worried my calculator perma broken
Hey i did not deleted ndless and i have a reboot loop problem, how is that possible?
I get the following error: “this document format is not supported” when I click on a image.jpg.tns file after installing Ndless 3.1 (latest) on my 3.1.0.392 device (Nspire CX) and installing Mviewer 3.3.
I thought maybe I did something wrong so I uninstall Mviewer and Ndless. But when I clicked on nless_resources the same error appear (this document format is not supported).
Is Ndless never been Installed?
I reinstal Ndless, device reboot but again these error’s please help me!
(sorry for my bad English)
Anna’s issue was solved here: http://www.omnimaga.org/index.php?topic=15542.0
For those with the same problem, check twice that ndless_resources.tns is stored in a folder named “ndless” in the top-level Documents folder.
where can i get 3.1????
Kb, get it from TI-Planet: http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
thank you very much
Hi, I did what was instructed. I got to the diagnostic menu, went into manual test, battery test. Battery Pack Test failed. Battery Pack Charging was passed. i went into battery pack charging and it said Charging Voltage/ Capacity was 100%. For some reason, the reset button isn’t working. i’m trapped in the diagnostic system. when i take the cable chargin my calculater off, it closes itself and doesn’t open unless i plug it in again.
please help >.<
dunno if this will help but under Charging Voltage/ Capacity, there is Charging is over: Yes/No and there’s a purple box flashing on No….Please respond as soon as possible
Daniel, you should let the calculator charge until “Charging is over” switches to “Yes”.
hi i have the ti-nspire touchpad and i upgrade my OS to the 3.1 now when i want to install ndless say that “experienced a problem while communicating with the handheld. a retry may be successful.” i alredy follow the instructions but it doesnt work can any one help
when i try to install the ndless the bar go half way and in my calculater it says that its install but the file doent show up
When I start to load the installer, it says “Ndless sucessfully installed!” , but it won’t stop installing on my computer.
I have the exact same problem. :(
Whenever I try to add the installer.tco , I am given a half loading bar or a nearly loaded bar for an indefinite am amount of time. And it says Ndless successfully updated, but it can’t load files after being pulled off loading prematurely.
My handheld restarts when i try to update the OS. I need help.
Dbob,
* Ndless is not compatible with OS 3.2. Make sure to downgrade to OS 3.1, available here : http://tiplanet.org/forum/archives_list.php?id=OS+Nspire
* Make sure to use the right ndless_installer-3.1.0.xxx file for your calculator:
.tno: classic TI-Nspire
.tnc: classic TI-Nspire CAS
.tco: TI-Nspire CX
.tcc: TI-Nspire CX CAS
I did that already though.
Is “ndless_resources.tns” (not renamed) in a directory called “ndless” (match the case) right under “My Documents”?
Does the folder HAVE to be named ndless?
Yes, please refer to the screenshot at the beginning of the page.
Thanks, I’ll try that.
I downloaded Pokemon Crystal once i click on it gives me an error message saying “This document format is not supported.
Ive read previous comments like Anna’s but everything seems to check out and i still have the problem
hirosheena: the installation of Ndless should end with a “installed successfully” message. Did you see it? If not Ndless is not correctly installed, please check the prerequisites and follow the installation procedure again.
Tell me if anything is unclear.
Did you add to the end of the pokemon file name “.tns”?
I intalled ndless 3.1 but i think my nspire cx wasn’t at OS 3.1, it was below that. Now my calc starts turning on and stops halfway thru the loading bar and doesn’t do anything. do u have any idea what i can do?
colorfulthoughts, please try to reinstall the original 3.1 OS once the bar is half-filled with TI-Nspire Student Software.
but when the calculator doesn’t turn on fully, it doesn’t show up on my computer.
Are you able to enter the maintenance menu?
Turn the calculator on while holding the following keys until half the progress bar: Doc+Enter+EE then ON
Your calculator should then show up in Student Software.
I installed Ndless on my TI-Nspire CX. In my ndless folder, I have ndless_resources and ndless.cfg. In GBA, I have game_config.txt, gba_bios.bin, gpsp_launcher, gpsp_resources and Pokemon_Emerald.gba. I try to load pokemon emerald, it says the format is not supported
Note: I do have the .tns at the end. Looks like this: Pokemon_Emerald.gba.tns
John, can you try to transfer and open Ndless’s particles demo distributed with Ndless (samples/particles.tns), to first make sure Ndless is correctly installed on your calculator?
Hi, i have been trying to install ndless 3.1 for so many times but every time it failed, and the thing that’s suppose to pop up saying that it’s successfully installed never comes up, I have put ndless resource thing correctly into the folder but i just can’t install it, what should i do?
Sam, what do you mean by ” every time it failed”? Does your calculator reboot or does Student Software refuses to send the installer?
If your calculator is a CX, use the .tco installer. If your calculator is a CX CAS, use the .tcc installer.
Also make sure:
- that the installer is in a *top level* directory
- that the directory is named *ndless* (mind the case!)
- not to rename the resource file
http://ndlessly.files.wordpress.com/2012/01/ndless_res_path.jpg?w=460
Thanks for replying, the thing is the thing telling you that you’ve successfully never pop out. I follow all the steps you mentioned but every time i click install “ndless os”, in the mid way my calculator reboots itself then nothing is installed, i don’t know what to do. By the way, i can’t extract the ndless folder after i downloaded it (http://www.unsads.com/projects/nsptools/downloader/download/release/1), my computer said it’s invalid or something.
I suppose you already made to sure to downgrade or upgrade to OS 3.1.
A reboot without installation confirmation popup is most of the time a sign of the file ndless_resources.tns not being found. Can you please double check that the file is stored where it should be? (same ‘ndless’ folder name, right under My Documents, same file name, , and ‘ndless_resources’ right under the ‘ndless’ directory)
About your extraction issue: Did you try http://www.7-zip.org/ to open the archive? Which computer OS are you using?
it’s really nice you’re trying to help, but I don’t know why i can’t install even though I have done exactly what you’ve told me, and i noticed that the size of my ndless_resources is 22KB, is that normal (different from the picture you’ve shown me before)?
Trying to fix my mates calculator that has this when it boots up (system error) http://www.mediafire.com/view/?jdp769i3rszq34r. I have wiped it using the maintenance menu, but it comes up when I turn in on. Its when it gets to halfway, indicating I think that its not OS but bios related. Is it bricked?
I suppose you are not able to get into the maintenance menu again to send a fresh OS?
Can you try to follow the section “The TI-Nspire CX falls into a reboot loop and ran out of battery” above, in the case the system error was caused by the battery?
I will try that. I did get to the maintenance menu though, and I formatted it, but even when it boots up without an os it still does it. Ill have a try later today. Cheers
Thanks so much! For some reason using the diags menu fixed it. It had 80% battery, but I just re-formatted it and now it works. Thanks heaps!!
