Hello everybody,

currently I'm using the NTAG NT3H2211.

 

Honestly, i was writing a lot of data on the chip without knowing where the data was saved. I assume i changed the capability container and/or some of the lock registers.

I am not really familiar with unlocking specific registers. Can you help me?

 

The first registry is filled with:

04 2F 25 E2

C5 4E 80 00

44 00 20 40

E7 78 FB 62

 

Config. Registry

01 02 F8 48

08 01 00 --

 

Session registry

01 00 F8 48

08 01 01 --

 

I hope this helps.

 

thanks alot
