my att g2 4.2 rooted stock rom worked normally last night, this morning I plugged it into the car charger and it displayed it was charging with 2% charge present. I pressed the power button the boot animation began I set it down and when I picked it back up a few minutes later to use it...well nothing...the charging indicator led wasn't lit and when I pressed the power button LG appeared for only a split second then went black. when I plug it in same thing, LG logo for a brief second then disappears. I haven't done anything recently except xposed modules, no flashing of anything. any ideas? thank you guys
