Hi @mifaresdk,
Attached picture is shown after I write block trailer 7 and 11 with new key. (49DB59CFF2F308778FFF2CBF23931A13) which is not readable.
When I use mifare classic tool in my android phone and load the all sector variable I use extended-std.keys files to read all the sector.
In my extended-std.keys files I include my new key as well. (49DB59CFF2F3 2CBF23931A13) and still cannot read the sector 1 and 2.
Kind Regards,
