Hello! I just ordered a Droid Razr xt912 from ebay, sold as-is for parts, and I need some help please. First when I tried to turn on the phone, nothing happened, then I plugged the charger in and a white LED showed up, but I was unable to turn the phone on, and it didn't charge, the charger was still cold. Then I took the back off, ripped an USB cable, and hotwired the battery. I let it charge for 3-4 hours, took the cables away, and voilá phone operates normally. BUT I still can't charge it through USB port. When its turned off, and I plug in the wall charger, the phone turns on, but says discharging, however its plugged in. When its turned on, and locked with blank screen, and I plug in the wall charger, the phone shows lockscreen and says "charging" but its not getting any charge... Another strange thing that when I connect it to PC with USB, nothing happens, phone just doesnt recognize the connection, neither the PC. I have a factory cable also, and that cable works with on USB port, so its maybe not damaged. If anyone is smarter than me please help me, I'm clueless !!!
