Dear NXP Team,
We have scenario in which we have customer's SAM so we only know Host Key which was used to lock SAM card and using same SAM we need to personalize MiFare Plus card in that case do we need to "Authenticate Host" or "Unlock" card? Or we could directly start personalizing card without authenticating SAM?
Because while trying to unlock SAM via NXP RFIDDiscover tool with key provided by customer we receive 6985 error but customer is sure that key and position is correct.
Could you please guide us to unlock SAM please?
Regards,
Tithi Patel
