Hands on: See the card in action

LibNFC - change UID

To update the UID of the badge, simply write the dump contents to the badge.

nfc-mfclassic w a u /tmp/1K.dmp

Proxmark - change UID

To update the UID of the badge, simply write the dump contents to the badge. When using wrbl - you are directly modifiying the card's configuration. Ensure that all data is correct including BCC - otherwise you will brick your card.

hf mf wrbl --blk 0 -k FFFFFFFFFFFF -d 11223344440804006263646566676869 # Where 11223344 is the UID, 08 is the BCC

Unbricking

"Soft-bricking" refers to when a magic card has been configured in a way that prevents it from being detected. Ways of soft-bricking tags include:

• Incorrect BCC
• Incorrect SAK
• Incorrect ATQA
• Incorrect ATS
• Incorrect ACL (Access Control) Values

Some "soft-brick" situations can be resolved with special commands. If your MIFARE Classic® Compatible 1K UID Modifiable is "soft-bricked", you can try recovering it with the following methods:

With Proxmark / iCopy-X

hf 14a config --atqa force --bcc ignore --cl2 force --cl3 skip --rats skip

Hf mf wrbl --blk 0 -k FFFFFFFFFFFF -d 04112233445566084400626364656667 --force

hf 14a config --std
hf 14a reader

Via external reader/writer and MTOOLS

Select the "UID Changer" function in MTools, select "bricked" and run the task

IMPORTANT:

Lab401 cannot provide refunds under any circumstances for cards that were 'bricked' due to incorrect configurations.
