Hmm wait. That command A2 and block 04 is for an ultralight or ntagā€¦ not desfireā€¦

23

Those UID changeable cards are just a uid. They have no memory or ability to interact with desfire systems. They simply respond to anticoll like a desfire card would.

24

Trueā€¦ but we use real desfire chips on the flexDF2

25

Hmm in the dataheet are only text commands and programming needs in hex.
Is there a datasheet with the hex commands

I can not use these commands in the ā€œnfc toolsā€ app under advanced commands.
Or is there a software that dous i own a asc1252U reader

The hex versions are probably on the NDA datasheet. Check the proxmark3 codebase, I known it has a few.
