TI Nspire CX CAS Stuck at bootup

Hello everybody,

Today i pressed the reset button on the back of my TI Nspire CX CAS. Since then it wont startup anymore. It is stuck on the gray screen with the clock cursor, which comes after the loading screen. I tried the maintenance menu. I tired every option. If i delete the OS in this menu, i can reinstall it but after the installation it is stuck on the same screen again.
I had the OS Version 4.0.235 installed.

Does anybody know a solution for this problem?
Im thankfully for every tipp.

Greetings

Just launch the diagnostic software and it should automatically detect and fix the error.

hold the keys
while holding the keys, press and release the 'reset' button on the back
it the calculator doesn't automatically turn on (it depends upon the hardware revision), keep on holding the keys and press

The calculator should now enter the diagnotics software, and give you a GPIO error.
Press

to fix it, and then reset your calculator.
