Htc one help!
I need some help. I just bought a HTC one international factory unlocked 32gb version but it seems the previous owner had it bootloader unlocked, was running TWRP recovery, and a custom rom. Now I am completely new to this unlocking/relocking factory stock flashing stuff. I looked up online tutorials on how to do this but can't seem to figure it out. I have downloaded ADT-bundle files and re locked my bootloader. Now I am trying to use the developer edition RUU installshield wizard but the wizard keeps crashing! I tried both developer edition RUU's off the XDA RUU collection thread but both keep crashing. Since I am unable to run the RUU wizard I am now stuck in the fastboot menu on my phone. The status still says tampered on top. Underneath it says relocked and security warning. PLEASE HELP!
