My HTC rezound said I have no signal last night so I restarted it via pushing the on/off switch and pressing restart. When the phone tries to boot up right when it is about to flash the 4G loading screen it freezes, turns black and restarts again. It never actually boots up. I have tried pulling the battery. I took it to the verizon store and the store manager said I was trying to root my phone and I caused it. But i have never tried to root my phone. He tried doing factory reset when you hold the power and the down button, still stops at the 4G loading screen then starts the booting over again. Anyone have any suggestions? Now im stuck without a phone!!
