Is boot2 1.4 completely compatible with Touchpads? When I use nsNandMgr to hot-launch it, it gets stuck at the clock screen which worries me about installing it for this...

It's not Boot2 1.4 but OS 3.1 which is stuck at the clock screen.
OS 3.1 and later cannot be hot-launched after another OS because of some protections.

And to answer your questions, the first TouchPad OSes (2.0 to 2.1.1) came with Boot2 1.4.

So if I were to install it, it wouldn't be a problem?

Seeing that it's only for calculators with 32MB of memory it would be a bit unhandy to have two of TI's large OSes on it. But the possibility by itself is cool :)

Might it not be possible to store only one version of the OS plus a patch file?  I assume that after removing all the layers of compression & encryption, the bulk of the OS is actually very similar from one version to the next, so the patch file would be much smaller than the complete OS.  Of course this would make it slower to start up, but maybe not by much.

Different OS versions do contain most of the same code/data but at different addresses, which complicates making a patch to turn one into the other. A simpler solution would be to make a patch to 3.2 that adds Ndless to it. This way you wouldn't have to reboot to switch between running Ndless and Lua programs either.

Agreed, but performing enough reverse-engineering to find function addresses on a new OS version takes lots of time :(

This is awesome!  Too bad I don't have a clickpad to try it out on.

I've translated the ReadMe of Ndless 3.2 switching pack into Chinese.
http://www.cncalc.org/forum.php?mod=viewthread&tid=8305
I think the ReadMe for CAS and non-CAS are the same except the extension of nlaunch, am I right? BTW, I think D6) :"If it's not the case, remove a battery and resume to C3." Should the C3 be D3?

I tried installing nLaunch on my non-CAS click pad, but it didn't work. When I tried to send the .tno file for nlaunch to the calculator via TI-Nspire Computer Link 3.1, it returned a message saying the file is "corrupt or invalid" and the transfer failed.

I've got Boot2 downgraded to 1.4.1571 with nsNandMgr, OS 3.1 with Ndless, and a directory for Nlaunch. Is there anything I did wrong?

Like ndless 3.1 fake OS, TI-Nspire Computer Link 3.1 can return an error. Did you check on your calculator?

Yup, I checked the calculator. Should I use a different linking program to send the .tno file?

First, make sure you really have the boot2 1.4. Then, if it still doesn't work, try another linking program... (still, it worked for me with TINCL 3.2 (3.1 doesn't exists)).
