If I press the power button I see the backlight go on and off, but I can't do anything else. I have Revolutionary CWM v4.0.1.4, and that works fine. I tried doing "wipe data/factory reset", "wipe cache partition", "Wipe Dalvik Cache", "Wipe Battery Stats", and "Fix Permissions", and none of tho (General)
