I would appreciate if anyone can explain what is happening and if I am doing something wrong.
I have MF Classic 1K card for house entrance which I was able to fully read using “Read” + “Detect reader + Mfkey32” (obtained key A for sector 5) + “Flipper Nested”. I am able to emulate it using flipper to open door but I can’t write it to MF Zero blank card (it becomes unresponsive/unreadable but I still can wipe it).
Why flipper report UID EF001495 when it different in sector 0 block 0? All of UID/BCC/ATQA/SAK reported by flipper are different from dump content. If I fix BCC/ATQA/SAK manually in dump flipper start reporting different UID.
Is it even possible to duplicate this key (using only flipper/MCT android app/PC)? I tried to change S0B0 to EF…95 UID with correct BCC but entrance reader don’t recognize (I mean it won’t open lock) key in that case.
