Hands on: See the card in action
The Ultralight® Compatible Direct Write UID Modifiable can be used with several tools:
LibNFC - change UID
To change the UID of your Ultralight® Compatible DirectWrite UID Modifiable tag with LibNFC, write a full tag dump to the tag, with the UID and BCC set appropriately. Do not use the
nfc-mfsetuid
tool to change the UID. This tool is built for MIFARE Classic® Chipsets, not MIFARE Ultralight® Chipsets - using the tool will permanently brick your tag.

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 Ultralight® Compatible UID Modifiable is "soft-bricked", you can try recovering it with the following methods:
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.
