This is another video about RFID rings, but mostly it's about what to do if you have a T5577 credential that is misbehaving, possibly due to being soft-bricked or being password-locked. There are some commands you can run (if you're completely stuck, I've listed them in order at the top of this doobly-doo) which may be able to recover your T55 card. If you don't care about why or how your credential got borked and you don't care about the data that may be on there and you just want a clear card (and its a real T5577) you can try those commands.
But of course I suggest you try the Proxmark's T5577 "Check" command to try the password dictionary attack first. Enjoy! 👍😁👍
