So I received my ring in the mail today, and immediately had trouble programming it. I eventually was able to clone my mifare classic 1k ev1 to it using my old android phone and mct, and I had set all access bits to FF0780 in an attempt to keep the ring modifiable. This worked fine for some readers, but I noticed the card wasn’t being recognized by my proxmark 3. So I took the steps to reverse a soft brick, and actually managed to rewrite block 0 and regain access to the ring. But instead of wiping it like I should have, I used the hf mf restore command to clone my card again, as I was too lazy to use my phone. Now i can only recover data from only sector 1 if I change the hf 14a config to ignore bcc.
The uid is also set to something I never intended to set it to, and I have no idea where it came from: 33 32 32 43
The keys & access bits for sector 1 (The only sector I can read without getting cmd error 04): 00 00 00 00 00 00 FF 07 80 69 FF FF FF FF FF FF
I’m assuming that the ring is permanently bricked but the fact that I can read anything off of it still gives me a sliver of hope.
