Not sure what pvt means but you should be able to use revolutionary method to get s-off.
Locked means the bootloader is locked, need to use htc method to unlock it.
The Fastboot, Recovery, etc. are options fastboot puts the phone in fastboot, recovery boots the phone into recovery, not sure about simlock i have sprint so no sim card.
If you do revolutionary method do it FIRST
before using htc method to unlock your bootloader otherwise you won't have s-off.
