UPDATE
I followed this video (by the way, great video @amal 
),
Which yielded some interesting results,
hf mf autopwn
And then,
hf mf cload -f filename.eml
Resulted in a write block send command error, I should note at this point I’m cloning to a Proxgrind Gen1A S50 and whilst the UID, ATQA and SAK have all been cloned all of the ‘Tag Signature’ data was not.
Doesn’t take much of a leap to infer that the partial dump file is the reason that this information is missing but is that inference correct? Is it perhaps an incompatibility between the hotel key and the S50 card?
And how do you think I would go about making that partial dump file just a regular old complete dump file?
