I successfully extracted the contents of a MIFARE classic card using mfoc-hardnested using mfoc-hardnested -f keys.txt -O extractedcard.mfd over an USB Adafruit PN532 Breakout Board:
# ./mfoc-hardnested -f keys.txt -O extractedcard.mfd
ATS len = -20
Found Mifare Classic 1k tag

However, when trying to write the dump back to the card using nfc-mfclassic w a extractedcard.mfd extractedcard.mfd, the process fails with

and the card remains unaltered. I'm using a fresh Kali linux and an uptodate libnfc (1.8.0).
Am I correct using nfc-mfclassic to write the dump back or should I use another program (since it identifies as a MIFARE Plus)?
Does anyone have an idea what the problem might be?
Thanks!
