After upgrade myTouch 4G firmware from 2.2.1 to 2.3.4, couple days later, during a visit to Android market, suddenly this phone stopped working, there is no response, and screen just stopped at the screen. I pressed the power button for over 5 seconds, and there is no response, nothing works. Tried remove battery, then put it back, restart phone by pressed power button and volumn down, tried factory reset, couple minutes later the phone reboot, then stopped at 'T-Mobile myTouch' screen forever. I tried everything I can think of, but the phone just won't boot, what I can do now? The phone is about 5 month old.
