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 mf csetuid --uid 11223344
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.
