I am new to Proxmark3 and have tried to look up some information regarding this issue but couldn’t find anything. I really would appreciate if someone can help me. I am trying to replicate a Salto fob (Mifare Class 4k 7 byte) and havent had any luck successfully doing so. I purchased fobs from Aliexpress that are 4k 7 byte UID changable as well but every time I try to write it on the card I get an error.
Im willing to pay for someones time to help me throughout this process, if you can guide me please let me know!
my first step I did
hf mf autopwn
Then I typed
hf mf cload -f hf-mf00477EB2A196F80-dump-5.eml
these are the fobs that I am using
