My RAZR, which I love dearly, recently got a little warmer than usual. Actually it was scalding hot. So hot that my battery drained from completely full to about 30% in 15 minutes. I turned the phone off to let it cool down for a little while, but once I turned it back on it displayed the "no service" error message at the bottom of the lock screen. I've tried wiping the cache first but that didn't work. Then I tried factory resetting the phone through the system recovery menu. Nothing that I have read about on these forums that has worked for other RAZR users has worked for me. I understand that the sim card is probably shot, but that doesn't explain the persistent overheating and rebooting when I remove the sim card and reboot into safe-mode. I still have about 6 months on my current contract and I'm waiting for the HTC One, but I need to have a functional phone right now. Please help if you can.
