flashed BW ICS build36 rom a week ago-phone has been working fine since. last i checked it, razr was at 47% battery strength. just went to use it and it is totally off and will not power up. tried booting into recovery by pressing POWER BUTTON AND UP/DOWN VOLUME BUTTONS TOGETHER and nothing. anyone know how i can get this "POS" flashed back to stock so i can tack it back to VZW????
