So I cloned a card to the XM1, and now, even after performing “cwipe” - which performs successfully) , I get this message from the proxmark when scanning:
[#] 1 static nounce 01200145
[+] Static nonce: yes
If I try to restore a dump, I get lots of Auth errors.
[#] Cmd Error: 04
[#] Write block error
[+] isOk: 00
However, using mfoc and a Acr122u seems to work
Also, running “hf mf cload xxxxx-dump.eml” (rather than “hf mf restore 1”) seems to work (no errors, but it does not appear to be an identical clone as it doesn’t work at work)
What does “static nonce” even mean? And is there a way to remove it?
