@aejb you can check on my fork of the PN532 library, and check for the differences or use mine altogether, i just included those functions and you can unlock your card with just calling the "UnlockBackdoor();" function
i haven't done a pull request because i believe its very sloppily implemented, also, it doesn't gives feedback if the unlock was successful or not, to make sure it works you could try reading all blocks of the card, or try writing to it right after you try to unlock it, without calling the "mifareclassic_AuthenticateBlock", if the action is successful it means your MiFare does have the backdoor

sorry to necro this issue, but i managed unlock the backdoor adding some functions from @AxisRay mifarecloner repo into Adafruit's library
perhaps its in a bit dirty way to do it but it works, i managed to write to an UID changeable block 0 and also read the whole card without authenticating after unlocking the backdoor

@SigmaDolphin how did you manage to do this?

Closing. Looks like not an issue but a request for help implementing a feature.
