Lock protection

Support
1

Hi all
Dispite doing a fair bit of research befor commiting
IV only just discovered the little instruction about locking the device to protect it

Unfortunately it doesn’t seem to work

IV only written to it twice using NFC tools
Once as a first test and second to test it still writable after the app didn’t work

Why isn’t it locked from the start? Can you not change the password?

IV made a dump from the tag if anyone can tell me what to do to get it protected

Ok according to this your lock bytes are disabled. Perhaps you had a tricky coupling and the DT app did its job and then re-scanned in very close succession.

3

Another question - is this a NExT or an xNT?

4

NExT

Ah ok so I’m safe from accidental locking then?

5

NExT Comes pre-locked as far as I know, Password is NExT.

At least Mine did.

That is correct, the NExT comes pre-locked

That’s good! I was getting a bit annoyed thinking there should have been something on the card on the pack at least. :slight_smile:
