Hello all, I rooted my thunderbolt about 1 week after it came out and everything was working great. I hadn't even bothered to load any roms on it or overcloak it or really do anything that requires rooting. About 3 weeks after rooting the phone, It randomly froze after sending a text message and so I pulled the battery out and replaced it and the phone would not turn back on. The battery was almost dead when I pulled it so I figured it was just a dead battery. I went home, plugged it in to the charger and let it sit overnight. The next morning I unplugged it and attempted to turn it on but it nothing happened. Long story short I have tried a different battery, I have tried to hard reset ( power and volume down) and nothing will help. I am wondering if anyone has any ideas on anything I can do to either A. Get it working normally, B. Get it unrooted or hide the fact that it is rooted so I can get a warranty claim. I work for Verizon Wireless so I am a bit concerned that if I process it as warranty and they find a way to turn it on and know its rooted I could get screwed. Worst case scenerio I have to spend 99 bucks to do an insurance claim, but would like to avoid that if possible. Any help would be greatly appreciated. Thanx all
