Here's the scoop:
After successfully installing CM 7.1 on my SGS2, I started to do the same on my girlfriend's. The procedure was as follows:
1) The phone was already rooted so I booted into CWM Recovery 5.0.2.3
2) I wiped data/factory reset, cache and dalvik cache
3) I installed the CM 7.1 ROM from the SD card. Everyone is aware of the bug in the CM 7.1 installation so I installed the CM 7.1 ROM again without rebooting as required. There were no errors during the installation.
4) I then rebooted the phone through CWM and it booted to Android OS just fine.
However the big problem is that my touch screen does not accept any input. A few seconds after Android OS starts up, the screen seems to dim and no matter where I tap my finger, my taps are not recognized. The soft buttons (menu, back) and the hard buttons (home, volume up/down, power) all work fine. In fact, they even bring up events in Android OS (eg. holding the menu key brings up a key board, volume key turns up/down the ringer volume). However, the touch screen or digitizer just are not working. Obviously rebooting the phone does not help. I also tried booting back into CWM Recovery and installing the Google Apps. When the phone restarts it asks me to "Touch the Android to begin" but again it does not register any input.
Through ODIN I tried to go back to two stock roms (XXKH3 and XXKI3) but those did not fixed the problem either. Obviously, these were flashed through Odin and prior to flashing them I cleared the data/cache/dalvik through CWM Recovery before hand. I also tried two nightly versions of CM 7.1 (115 & 116) as well as Litening ROM 6.1 and Villain Rom 3.0 but those did not help either.
My feeling is that this is not a hardware problem, rather a corrupted driver through one of the ROM installation processed. While I am fairly well versed when it comes to problem solving technology issues, I am not familiar with the Android OS structure to go any further. For example, are the drivers for the touch screen and digitizer embedded in each ROM or on a secure portion of the physical phone?
Please let me know if you have been in a similar situation or whether you can pass along any tips that I should try. Again, my girlfriend's phone was working perfectly before the ROM upgrades. And I know my upgrade process was correct as my phone that I upgraded just an hour earlier is running CM 7.1 very well.
Any help is appreciated.
Thanks!
