I was just trying to use the app to secure a new xNT implant, and moving my phone to get the ‘sweet spot’ lined up, the app started to write while I was stil moving the phone then I got an error that the tag was lost.
Reading the tag with NXP TagInfo, I can see that the lock bytes in address 03 were written but the stuff at e2 onwards was not.
The app won’t let me try again now as it says the lock bits are already altered.
So from what I can see, LOCK0 and LOCK1 were written but LOCK2 - LOCK4, the password, and the PACK bytes were not.
Here’s the lines in question from the TagInfo app:
02 * 51 48 0f 00
03 * e1 12 6d 00
e0 . 00 00 00 00
e1 . 00 00 00 00
e2 . 00 00 00 bd
e3 . 04 00 00 e2
e4 . 00 05 – --
e5 +P xx xx xx xx
e6 +P xx xx – --
How badly is this going to affect things? I’m guessing that technically those LOCK2-LOCK4 and Password bytes can still be written to as they’re not marked as locked or blocked? But the DT app won’t do it any more?
