Help with bricked TI-Nspire CX (Revisison C) - Solved

[nghephuhao]

I need some help with my TI-Nspire CX which I tried to install nBoot and ControlX when I tried to repartition the flash. I was not intending to install Linux, and I intend to install a CAS OS on my non CAS model. When I reset the calculator, the calculator gets stuck when booting, not showing the No OS screen. I accessed the maintenance menu and formatted the entire flash (OS included). After I reflashed the OS (4.5.3.14), it boots up normally but gets stuck on the gray screen with the clock. I have tried reforrmating the flash 3 times, but it didn't work. I had also found the secret check flash option in the maintenance menu, but it didn't work too. I also flashed a newer version (4.5.4.48), but it still didn't work. I had backed up the boot1, boot2, diags partition via PolyDumper before. Any help would be helpful.

Note: I used the check flash function after I install the new OS version and now it's stuck forever.

Note 2: II cannot access the Diags boot at all.

Final note: I somehow made the calculator to boot. I erased the flash and performed a flash check but ended it early. I then flash OS 4.5.4.48 again and now it works. Now I could continue the install process of nBoot and ControlX.

How to enter the hidden Check Flash function in the Maintenance menu

Step 1: Enter the maintenance menu.
Step 2: Press 5 on the menu screen
Step 3: Press 1 to proceed

Thats pretty much it.
