htc one v "this build is for development only"

[shaimsam]

Hi my son's cell is stuck to that red writing. "this build is for development only"

He did many "suspicious manipulation" He told me he tried to put a rom.

Is there any way i can easily return to factory setting? Im a newbie... thank you
