I have this phone too. Unlock bootloader of this phone is the same as other variants, except that you must use JB rom of P760 to unlock, so it's hard to do steps because your screen will be mirrored and touchscreen goes crazy.
- First flash v20b kdz of P760
- Then install fastboot driver, plug your phone, type oem-unlock command
- After that bootloader will be unlocked.
- Finally, fix touchscreen
PM me if you have question
Thanks? I don't need it. I GIVE IT!
