Well, sorry. If you haven't read on other threads, the theory is that the ones that can't be unlocked have an encrypted bootloader. This has been asked soooooo many times before and that's why you don't have responses. It's like beating a dead horse...lol.
I guess you can try using older drivers but honestly, it may not work. You should send an email to LG stating that you own the P760 which is officially approved for bootloader unlocking with v20b but is not working.
Unfortunately, LG holds the keys to the gates. All we can do is hope for an exploit...and even that may never happen. I know it's not the help you were expecting but that's how it is.
