Hi everybody,
I have a somewhat reversed question. I recently broke my screen, and ordered a new digitaliser + LCD screen from AliExpress. The thing works perfectly and looks marvelous, and before mounting it I decided to test it and the digitiser and screen worked perfectly fine. Now, I glued the new screen to the chassis and booted the phone and it seems that half of the screen refuses to work. The top half works, the lower part doesn't and the soft buttons work again. According to the different fora I searched on for more information, this might be a software issue (since the digitiser worked perfectly fine before). When I attached the screen the first time the phone showed this "Touchscreen firmware update in progress" thing. Seemingly, this is the calibration phase the phone goes through to fix any calibration errors.
Now, I want to force the phone to go through this phase again, but for some reason, before every time when I had the previous screen and digitiser it went through this every single time I upgraded the rom, but now it doesn't do that at all.
I reinstalled different recoverys: TWRP and CWM (no calibration phase), I reinstalled different ROMS (cyanogenmod and Paranandroid) and I installed different modems (4.1 and 4.2), none of them had the result of pushing the phone into the "touchscreen firmware update in progress" phase. Any idea or tips how I could get the phone into this process?
Thanks a lot for your help!
