I must first apologize for the endless flow of unanswered requests for updates.
The long awaited Ndless 4.0 is out thanks to the hard work of the team, compatible with OS 4.0.3. It will let you run native programs on the latest TI-Nspires. The installation (and reinstallation on crash/reboot) does not require to be connected to a computer for a smoother experience.
Get Ndless 4.0.
Follow the installation guide.
Load your TI-Nspire with native programs (maybe crafti or MicroPython?)
ndlessly 
Does the Boot2 and Boot1.5 let me flash the past versions of Boot2 with nsnandmgr? My calc is HW-C, i know it can run.
Yes, you can flash older Boot2 versions which are going to overwrite your Boot2+Boot1.5 4.0.3 pair.
Will this work by TTL interface? If future versions come out, I want to test them :)
Is it only for CX? What about CAS with Touchpad? Left out again? :(
There is no OS 4.0.3 for CAS with TouchPad to begin with.
Oh, didn’t knew that. I assumed there is. :) I’m stuck on 3.6 anyways because there is no ndless for 3.9.. :(
Thank you for replying.
Awesome work! Thanks!
Thanks guys!
Ho Ho Ho that’s cool now i can reactivate my big black door stopper. Thanks !
Yes!!! finally!!!!!
Haha! I literally got my CX CAS replacement (lost the old one :( ) today. First thing I do is go to get ndless, and lo and behold, here it is, not a moment too soon.
Hey, My TI-nspire CX CAS is 4.0.3.29, and i wanted to install ndless 4.0. so I made a file named “ndless” and pasted files: “ndless_installer_4.0.3_cascx”, “ndless_resources”. After I opened the “ndless_installer_4.0.3_cascx” file and pressed Ctrl+W, and it poped out to main menu but the green words on left top corner was missing. I have tried several times but it just don’t work. So, I thought it was not supose to have green words. So I went ahead and downloaded and moved the gba emulator and game DOS files. But it still wont work. PLEASE SOMEONE HELP
It can happen if the installer doesn’t find the “ndless_resources” file.
Are you sure you put the “ndless” folder at the root of the documents tree ?
It means at the same level than the “MyLib” or “Example” folders.
I have a TI-nspire CX CAS 4.0.3.29, and I would like to have ndless on it.
I created the “ndless” folder under the “My Documents” section and copied the “ndless_installer_4.0.3_cascx” and “ndless_resources” files to that folder.
However, once I run the installer and press CTRL+W, it goes to the TI-nspire loading screen and then to a new screen with a gray criss-cross background and a watch in the center. After that, it returns to the home page and no green letters appear say it was installed. Is anyone else having this problem?
The product code on the back is “P-1115W” if that helps.
Thanks!
Unfortunately, Ndless 4.0.3 is not compatible with calculators using the new hardware revision W yet. :(
Have the same problemT-T
Is it possible to downgrade back to 3.6? Some programs don’t work on 4.2 (because the calc doesn’t reboot)
is 4.2.0 work with the w revision? if not, how long will it take because i want to use my calc :/
It’s currently being worked on and should be ready soon (1 or 2 days)
Hey there Vogtinator, I’ve been reading some of your posts and you really helped me a lot and I thank you for that but I’d like to raise a question. When I take a file from my CX CAS on .TNS and I need it in the original form, how I remove the .TNS extension? I’m asking because I’d like to play my pokemon saves(.SAV files) in the pc emulator and then pass it to .TNS again so I can play later on my CX CAS. I know I only have to name it .TNS to get the file on .TNS form but I don’t know how to get it back to its original form :/
Is there a fix for Revision W yet? I have Revision W on 4.0.3 and it doesn’t work. Can someone please tell me what is wrong? I have created an ndless folder under My Documents and I added the installer for 4.0.3 CX CAS and the resources.
I upgraded the OS to 4.2. It works now!
Hi, I’d like to know how to convert .TNS files back to its original form. I’ve a .TNS wich was a .SAV, I’d like to have .SAV again…
I assume this will not work with the dual boot method (CAS 3.2, regular os 4.0.3)? If it does, I’d update instantly.
I should probably clarify that I’m asking specifically if os 4.0.3 is nLaunch compatible.
nLaunchy seems indeed to be compatible with OS 4.0 ( https://github.com/Excale/nLaunchy/issues/9 ) and OS 4.2 ( https://github.com/Excale/nLaunchy/issues/11 , https://github.com/ndless-nspire/Ndless/releases/tag/v4.2 )
Is this going to work for 4.0.0.235?
Does it work with TI-nspire CX P-xxxxP?
Hello, this page has been very helpful but sadly my Ti-nspire cx is on version 4.3 and I have tried everything to downgrade it and replace it but it will not work. I was just curious if a version of ndless will ever arrive for 4.3? Thank you
Same here is there any version of ndless 4.3 coming out soon?
I have problems with installing ndless. I use the right version and the cx file but my calculator always crashes. Can somebody help me?
Ok, so i did everything to install ndless, i put the correct files in a seperate folder named nless and everything, well when i launch nless and the ctrl w thing shows up, it reboots the calculator but thats it. Nless is not installed. Can anyone help?
Whats about Ti nspire cx 4.0.0? please help!
Just update to 4.0.3, there are barely any changes. Or use 4.2 or even 4.4.
why does it crash after closing the tab?
