I wanted to root to Htc Evo phones. The first I rooted it and used wifi tether with unrevoked 3. On the second one i tried rooting it with unrevoked 3 but after i connected it to the htc evo the unrevoked app was rebooting and i followed the instructions. But then it said "failed to flash recovery image". I tried several times mounting it as a disk drive and normally charging it. Please help as i need this one rooted to.
