I've got a Droid 2 R2-D2 running Liberty Rom 2.0.1 and Kernel version "126.96.36.199". The touch screen is beginning to short out (same thing happened with OG Droid) It will randomly start clicking things. But unlike my OG droid situation R2 is still under warranty. When rooting/sbf'ing my R2 I remember something about there being a difference in the R2 & Regular Droid 2 Firmware, and to get liberty or root (I cant remember) i had to flash the Regular Droid 2 firmware. I think I recall something about not being able to change back to R2's firmware. I'd like to get it back to stock R2 stuff (firmware, custom unlock screen, ringtones, etc.) before trying to return it for a warranty. Any suggestions? Is it even possible to get stock R2 firmware back on it? Would Verizon take it back with liberty rom? Would they take it back with Regular Droid 2 firmware on it? Any help would be greatly appreciated!
