uid changeable mifare 1k card block 0 writable I bricked a Mifare 1k tag during an attempt to write to block n°0 (to change the UID), I would like to understand what I did wrong. Just for reminder, the datasheet of the Mifare 1k => 1. I used : a Proxmark Easy ; a tag with a writable block 0 (bought online). First, I searched the tag. proxmark3> hf search. $22.89

writable uid card

you change the manufacture block (block 0) using a normal write command. hf mf wrbl —blk 0 -k FFFFFFFFFFF -d [new block 0 data] you’d take the block 0 from the card you’re copying. DO NOT mess around and try random values you can and will brick your card if you write an invalid block 0. you need to be precise. I have some uid-changeable gen2 hf mifare fobs that I am trying to clone to. I understand that each block is writable via hf mf wrbl --blk 0 -a -k key -d data and yes I was able to write each block OK so I cannot set UID via csetuid or normal wrbl on block 0 with correct keys. However the card IS uid changeable because I used my other hand held machine to read the ID from one card and write to this card.

Mifare 1k Magic UID Reset is a tool that allows setting of UID on special versions (magic cards) of Mifare 1K. Those are also called Gen1 UID Re-Writable. It will also recover damaged cards that have had invalid data written to block 0 (e.g. wrong BCC). Currently only 4 Byte UID is supported. IMPORTANT: There are three different types of cards that you can choose from: Type 1: Normal GEN1 UID Changeable Cards: All blocks (including Block 0) can be re-written multiple times. Use ProxMark3 (Magic Chinese Guy function) or libnfc to change UID. Uses "backdoor" technique to change/rewrite UID.UID Changeable cards are used to duplicate MF 1K access cards. All three types of cards can be programmed with the Proxmark3, ACR122U or iCopy devices. These tags are in white PVC card format and some features include (Type Dependant): Supports fully unlocked read / write. Impossible to block / brick. LibNFC / nfc-mfclassic compatible (New!)UID writable Mifare 1k 7 Byte Gen 3 / APDU variant. Not all ‘Chinese Magic’ cards are alike. There are many chipset types, each with different levels of reliability and functionality. All blocks (including Block 0) can be re-written multiple times. Use ProxMark3 (Magic Chinese function) or libnfc to change UID.
