setting & Dump Mifare Classic 4K

[milcaca]

I Have 2 issues the first one is that I can't set the slot via dialing through socat :

SETTING=2
200:UNKNOWN COMMAND
SETTING?
101:OK WITH TEXT
0
SETTING=?
202:INVALID PARAMETER
setting=2
root@kali:~/ChameleonMini/Software# 

Any reason why ?

In addition to that I'd like to know if it's possible to dump a classic mifare 4K data from the reader ?

thanks for any help

Hi Mica,

Which command did you used for socat? Try "socat -,escape=0x0f /dev/chameleon,rawer,crnl" .

opens an interactive connection via the serial line, e.g. for talking with a modem. rawer sets the console's and ttyS0's terminal parameters to practicable values, crnl converts to correct newline characters. escape allows terminating the socat process with character control-O. Consider using READLINE instead of the first address.

Also, see issue #64

I don't know if you can read anything besides ultralight. Maybe you can get some data using the advance commands, but I did not tried (that hard) and never managed to obtain any data.

Hi @milcaca,
the firmware does not yet support reading/dumping MF Classic cards, but it has all the functions you would need to build something that would dump a card (when the keys are given).

Did the hint from @Peterthegreat solve your other problem?

I managed to make it working, thank you for the help.
I have another question. I uploaded the provided MF classic 4K dump and tried to read it with a reader and that was not possible. Error say connection ended. Any idea of the reason ?

[Peterthegreat]

Please provide the log from the emulator. (Using software/chamlog.py)

I'm trying to reupload the dump for verification but it always wails with this error

Ok I finally got the log (previous issue just stop at reboot ...)
I get this :

Looks like the emulation error that is present in the latest firmware. I notice the bug but I am currently out of town and cannot identify the exact commit where the issue appeared.

EDIT: You can try tree e8d6c8

But you must first compile the source. The .hex and .eep files will appear in ChameleonMini/Firmware/Chameleon-Mini/

[milcaca]

I'll try that, thanks for the help

edit:now works perfectly, any news of the fix ?
