Root Operator error...need help

[Nate.davila]

I rooted a friends phone and the stock naindroid back up we did failed. I need a way to flash a stock "sprint return passable" HTC EVO 4G rom. Please help. Dont want to be the cause of his warranty being voided. Thanks

Is he returning the phone or taking it in for service? What hboot does he currently have?

He is returning the phone. Hboot 2.10.001 says s-off. It will not even reboot flashed Rom, just stays at bootloader screen. I can get into recovery and apply from zip, but when I try to recover any restore says md5 mismatch. Is there some zip File I could move to his SD card and flash stock ROM? I've read about some ruu.exe file, but I can't. Even get phone into sync mode nor understand what I would do after that regardless. Please help.

Go to the rooting for dummies guide and follow the directions in the after rooting section under unroot.
