PROXMARK Remove Blue Cloner Password
There are a couple of approaches to this, but for simplicity sake, I will post the one I THINK is the easiest
Wipe the implant / fob / card back to T5577 using the password, something like this:-
lf t5 wipe --p 51243648
Then write the new mode to it as per Proxmark instructions ( Found elsewhere )
Thanks @TomHarkness for the Blue Cloner Password
