What? I am pretty sure the OP was talking about the bottom buttons of the G2x (menu home back and search) don't light up at all for him. Not about flashing or anything.
As far as I know, this sounds like a hardware problem not anything to do with the software of the phone. Your best bet would be to call T-Mobile and they'll probably end up sending you a replacement.
