Can somebody please help? I tried installing ndless on my nspire cx shut it off and now it boots to a system error everytime. Deleting the os isn't helping.

Not sure what to do, please help thanks

How exactly did you try to install Ndless on your Nspire CX ?
What is the hardware revision of your Nspire CX ? It's the last letter of the P-<4 digits> <letter> code at the back.

P-06140; The back of the calculator is white.

I tried this tutorial:

Sadly, you followed an inadequate, careless tutorial, and you couldn't have known that the tutorial was junk. That tutorial does not take care of warning about the pitfalls of newer hardware revisions...
TI-Planet's tutorial ( viewtopic.php?f=76&t=13213&lang=en ) avoids that blunder, but we have no control over the dangerous content that gets posted elsewhere...

You have successfully flashed an improper version of the boot2 onto your calculator, and it's now in need of repair through special (if cheap) equipment... See the very recent http://www.cemetech.net/forum/viewtopic.php?t=10663 topic: you need to apply the same procedure for fixing your calculator.

Well shit. Thank you very much for the information, I appreciate it.

You're welcome
Good luck. Fixing the calculator is not that hard if you follow the procedure accurately, and USB / RS232 TTL adapters (based on e.g. FTDI232, CP2102 or PL2303 chips) are much cheaper than Nspires, but it's always annoying to semi-brick one's devices and have to fix them afterwards.

sorry to retrieve the topic , I did the same thing and I have a CX - N revision with OS 3.6.550 and when I inject the boot2 which I should put ?

[critor]

None.

Boot2 3.2.4.7 is the only one working with TI-Nspire CX hardware revisions J+.
So don't reflash it.

So don't reflash it.

I don't understand this part! what did you mean?

Thanks for your help!

[critor]

Don't replace your 3.2.4.7 Boot2.

You'll just end up bricking your calculator.
