My friends Motorola Razr v3 just randomly turned off and wouldn't turn back on again. A few months later, mine did the same. At first, it would turn on to the Motorola screen, but then it wouldn't turn on at all. I tried taking the battery out for a few hours, then putting it back in and charging it. Then I tried turning it on, and it vibrated once, but hasn't done anything since. How can I fix it? I really like this phone, and the warranty is expired.
