First repair/wipe security with octopus box then write the original imei with z3x, after it restarts make Patch certificate with z3x, after reboot try unlocking.

Works for me every time.

Which option would you use to repair / wipe security? because there are only 2 options for security read and write. Also i got the phone with damaged security. i dont have the original security backup.
