Hello I bought an htc evo 4g lte recently and when trying to update the htc software on it i noticed a team win recovery project screen coming up. I just want me phone back to stock . the phone is also rooted and has supersu on it. how to I get the phone back to complete stock? I have a mac and have no access to a windows computer. I know that the phone is rooted because i rooted it through my computer by downloading a root and typing instructions through terminal but how do i unroot it and remove the twrp?
