Title: Help with a bricked Ti nspire CX
Post by: tyrleng on July 06, 2019, 05:04:50 am
Hi all,

I have a ti-nspire cx calculator that is stuck on the loading screen, the progress bar is roughly 10%.
It was meant to be running on a nloader bootloader for Non-CAS OS.

I had actually followed the steps in this link to install a CAS OS at first, ( , configuring my settings according to what the tutorial stated. The calculator booted fine for the nLoader for CAS, and I managed to install the CAS OS without a problem.

I needed to revert the OS to a non-CAS OS for exams, so I created a non-CAS nloader image and flashed it over the previous CAS nLoader image. I didn't do any of the other steps, like resizing the partitions or reflashing the Diags partition since I thought those weren't needed. I then rebooted.

If it wasn't because I skipped the steps that I didn't follow in the tutorial, then I might therefore have did something wrong, e.g. flash over Boot1.5 4.40.8 in the Boot2 partition instead of the previous nLoader partition.

Anyway, when I rebooted, the calculator got stuck on the boot screen, so now there's no OS inside and the bootloader isn't working right. Anyone got any idea for how to rescue this calculator? I would really appreciate it, the ti nspires aren't cheap haha.

It's fine guys, I discovered the problem. The bootloader I created was faulty, since I didn't follow the steps in the guide properly.

For future reference to anyone who's Ti nspire bootloader fails too, press esc + menu + minus all at once, and whilst holding the three buttons, press the reset button at the back of the calculator. The Ti nspire will boot into your Diag partition, where you have a chance of salvaging your calculator.
