Hello. I have an G502 SE, that is not working anymore. The display is freezing, and then black screen appears. I tried to flash it, but the same problem happening after that. I think it's a hardware conflict. Anyone had the same problem ? Any suggestions about how to repair it ? Before trying to flash, it worked fine, but sometimes, the black screen appeared and the phone restarted. I can't get what problem does it have. Sorry for my bad english.
