Well today for some reason, my hero isn't working anymore. I had not changed any settings nor flashed anything or even charged it wrong. The symptoms are that everything appears to be working except the screen. A battery pull makes it so the phone vibrates when its turned on, and the buttons at the bottom even light up when used. I think its a screen problem because if not for that, the phone would work fine. What would cause this and is there any way I can get this fixed?
