Re: Cant Crack Mifare 4k
I don't think its any problem with the firmware version. I would think you two don't have a RDV4 but insists on using a fw compiled for it instead of using a fw compiled for other proxmark3 devices.

Re: Cant Crack Mifare 4k
Indeed I am not using an rdv4, i did Try it for the sake of autopwn. ( I used the precompiled version Generic)
As I have troubles compiling myself and always got the wrong Keys using the other precompiled versions I gave it a shot.
Is it even possible to read the sector if you dont have either key A or B of that sector? Maybe someone has a bigger Keylist to try?

Re: Cant Crack Mifare 4k
I had the same problem one time. And solved it by updating to the latest firmware/software. Update your Proxmark and try it again.
