[crude_dude823]

I have had my incredible 2 for a little over a year now and when i go to turn my phone on all I get is a vibration then nothing. I know it's not my battery because I have tested it in another phone plus my charger works perfectly fine also. I really need this forums help since i have everything I need on it and can't loose my phone PLEASE HELP!!!!!!.
