Boot failure, sudden restarts, glitchy screen, and unresponsiveness.

So the other day, I left Ndless on my calculator too long, and I took it out to find that there was a glitched screen left on all night.

Calculator Info:

  • TI-Nspire CX CAS
  • OS
  • Had Ndless installed (4.4.0 r2007)
  • Hardware revision O (0?)
  • Was using nPDF

Current Symptoms:

  • Sudden restarts
  • Glitchy screen (Usually during restarts)
  • Does not respond to resets when reset button is pressed
    • Restarts when disconnected from computer (Battery?)

What I've done so far:

  • Reinstall OS.
  • Delete, then reinstall OS.
  • Take out and put back same battery.

I would give images, but due to the buggy nature of this problem, it simply won't cooperate.

Update (8/16/17): Today my TI-Nspire CX CAS gave me a glitched TI-Nspire Classic boot. Of course, it glitched, but still, it was something.

Edit (11/20/17): My calculator doesn't turn on anymore. Help!

Hmm, that's an interesting problem! I haven't seen that before, but my best guess is that you heat damaged the board.

Try taking it apart and see if anything is amiss.

You may need to get a new main board. Perhaps you can find a donor unit with a cracked screen.

Actually, the problem only started after a jailbreak software was installed too long, it would be a strange coincidence if it were the heat.
