MIFARE Classic 4k - Issue while dumping data

I'm trying to dump data from a MIFARE Classic 4k card. When I use hf mf dump command to dump data from the card, I get the below error.

pm3 --> hf mf dump

Now I'm not sure why i'm not able to dump the data. Any suggestions here?

Re: MIFARE Classic 4k - Issue while dumping data

My bad. I had to specify the key file name like - hf mf dump 4 k dumpkeys.bin. I'm able to successfully dump the data now.

By default, the command takes UID as the file name.
