About the soft-bricked NTAG
What’s the soft-bricked NTAG?
It won’t be read by the NFC hardware on the Android phone or iOS device due to the invalid BCC byte.
How to fix the soft-bricked NTAG?
A Proxmark3 device is necessary to change the communication rules such as ignore BCC, skip RATS, skip CL3.
Here’re the commends to bring the bricked NTAG back to life.
hf 14a config --atqa force --bcc ignore --cl2 force --cl3 skip --rats skip
hf mfu setuid --uid 11223344556677
hf 14a config --std
hf 14a reader
It works as advertised. Great product!
I’ve used several different types of NFC tags, but this one is by far the best when it comes to changing the UID.
If you’re looking for a reliable and easy to use UID changeable tag, this one definitely fits the bill.
