| WP8 Lumia does not have PUK... Unlock attempts are unlimited but with delays.
20-digit unlock code is saved in a fat16 file "unlock.bin" similar to PM 120-3...
This file does not get erased even when you flash phone.
It gets invalidated when carrier releases updates to "disable" unlock.
Try to downgrade phone with low version, it should accept the code
again... that is if nothing is wrong with the code.
