Writing to a gen2 mifare classic 1k

Is it possible to write a an .eml file to a gen to mifare tag, I have tried the cload command but getting an error:
"Can't set magic card block:0"

If you can, what is the command?

This is what I am getting:

proxmark3> hf mf cload filename
No chinese magic backdoor command detected
Loading magic mifare 1K
#db# wupC1 error
Can't set magic card block: 0
proxmark3> hf mf csetuid 01020304 0004 18
uid:ca f4 10 14
--atqa:00 04  sak:18
No chinese magic backdoor command detected
#db# wupC1 error
Couldn't get old data. Will write over the last bytes of Block 0.
new block 0:  01 02 03 04 04 18 04 00 00 00 00 00 00 00 00 00
#db# wupC1 error
Can't set block 0. Error: 2
Can't set UID. Error=2

Thanks

Dave.

Re: Writing to a gen2 mifare classic 1k

The c* commands are for the cards with Chines magic backdoor.  If you have a gen2 card then the chinese magic backdoor commands won't work(as confirmed by the output).  IIRC gen2 just has sector 0/block 0 unlock so it can be written, otherwise, you have to write everything like a normal card.

I think iceman's 2 part video here: https://www.youtube.com/watch?v=idtBV9wr0Eo should explain a lot.
