rezound wont do anything

i got a rezound from a friend cause the power button was broke. i fixed it and turned the phone on and it got stuck on the white htc screen. i have read for days trying to get this phone to work and nothing. all i know about the phone is what ive done to it. fastboot is the only thing it will do. wont go into recovery or anything else. i did get it unlocked and it says tampered above unlocked and s-on. i did get it to get to the recovery part with the green arrow circle but then it cut off and i cant get it to do anything except fastboot now. any suggestions on what i should try next?
