Error when trying to write to xNT with NFC TagWriter by NXP

This was the primary line I wanted to see… it indicates the “static lock bits” are locked while no other pages have been locked… this effectively disables those lock bits.

This is the other line I wanted to see… the “dynamic lock bits” are also “disabled”.

What I did not expect to see was a boatload of binary data from page 9D to E1… those “UUUU” pages are not encapsulated within an NDEF record, so my bet is that most Android apps will not know how to deal with that data. How did this data appear? What else have you been tinkering with?

Definitely check out this post; The xNT and the mysterious 46/48 byte problem

We will be updating the Dangerous NFC app soon to incorporate support tool function and enhance its capabilities to include full blanking, resetting NDEF records, changing the password, and some other things… for now though the tools were kind of built to deal with particular issues that were pressing at the moment.
