problem is that his bootloader shows ***Locked***.
If you go through htc-dev it would have shown ***Unlocked***.
This is why I would start from the beginning flashing a GB RUU and then start again the upgrade process.
My humble opinion, of course
HTC unlocked doesn't s off the phone and that's what matters, you void your warranty for a half unlocked bootloader, it's a pos, IMO.
