Unbrick Mifare DesFire EV2 Compatible badge?

Dear community,

I recently bricked a 7byte DesFire EV2 Compatible badge by setting a 4byte UID and thereby messing up the BCC (at least I think that this is the issue). I've looked through some of the documentations out there but I haven't found a way to fix my mistake.

The badge will still react to the WUPA/ANTICOLL/SELECT_UID sequence but does not reply to the RATS.


I know that it is unlikely, but does anybody know of a way to fix the badge?

thanks!
