I am very new to the nspire, as I bought it off craigslist to replace my Ti-84. I heard great stories of the mods and programs you can add, so I updated to 3.1, and was going to install ndless. The problem is, now that I updated to 3.1, my touchpad doesn't work, there is no cursor, my buttons have random inputs (The calculator thinks 8 is A, 2 is B, T is 2, N is 5, and so on.) It has no functionality now pretty much, as I can barely even navigate the menus. I really don't want to update to 3.2, so if there is a way to fix this or downgrade, please help! And thank you so much for reading this!

Try pressing the reset button on the back and see if that helps.

Also, remove the batteries for a few seconds. Try with a different keypad too - maybe it's just the one you have that's shot.

It's not random. The handheld mistakenly things your touchpad keypad is a clickpad keypad.
Remove it, reinsert it firmly and reboot.

Hi, I have exactly the same problem of OP: upgraded to 3.2 and now the handheld is unusable. Tried to remove/reinsert and reboot but nothing. Any ideas? I've already tried with reset and all the procedures here described (http://epsstore.ti.com/OA_HTML/csksxvm.jsp?nSetId=109888).
There is a way to solve it without the forced downgrade via serial port (obviously if it is possible to force the downgrade form 3.2)?
thank you!

If you want us to be able to help you, you'll have to explain more.

When I bought it the calculator had the 2.1 os version. Trying to update it to 3.2, both Ti computer link and TI nspire student software told me that the handheld was already updated, but that was obviously impossible. Also when I tried to open on the calculator some text files created with the student software (student software version 3) appeared a window that said "files not compatible, upgrade to 3.xx". So I deleted the 2.1 OS with the procedure described on the site and updated to version 3 OS. And here's the problem, that is the same as OP: touchpad doesn't work, keys with random imputs...really seems what you (critor) said: the calculator thinks that the keyboard is a clickpad one. Tried reset, tried all reboot procedures and OS reinstallation but nothing. Any ideas?
thanks in advance

Apparently the problem with my handheld is that deleting os 2.1 I should have done a 1.7 installation and then an upgrade to 3.xx. Now I'm trying to downgrade via the serial port but it seems that Hyperterminal doesn't see the calculator. Any tips on how to connect it (I have followed the steps on the guide many times but nothing)? How much time I must wait to know that the connection is established?
thanks

IIRC, HyperTerminal doesn't work, but lrzsz does.
