https://stackoverflow.com/questions/41326384/re-writing-uid-and-block-0-on-chinese-supposed-to-be-writable-mifare-1k-card-i
There are 2 types of UID writeble cards:
Block 0 writable cards: you can write block 0 at any moment
Backdoored cards
If writing block 0 does not work, you probably have a backdoored card: To enable the backdoor, you need to send the following sequence to the card: (everything in hexadecimal)
RC522 > Card: 50 00 57 cd (HLTA + CRC)
RC522 > Card: 40 (7 bits only)
Card > RC522: A (4 bits only)
RC522 > Card: 43
Card > RC522: A (4 bits only)
Then you can write to block 0 without authentication. If it still does not work, your card is probably not UID changeable.
