Cracking Mifare Classic 4k

I have a question about the cracking the Classic 4k card.

I am running the mifare_autopwn.lua script, then trying to clone to a writeable 4k card (from clonemykey)

This process worked with a 1k hotel card and a 1k UID changeable card from rysc, however when issuing the "hf mf cload emlhere" command, i get this error:
proxmark3> hf mf cload xxxxxxxx
#db# wupC1 error         
Can't set magic card block: 0

I can use the "wrbl" command and write the entire first block manually to the same card I am trying to clone, but I can't clone the entire card with the same method as the 1k card.

EDIT: realized the 4k cards from clonemykey are not chinese magic cards, therefore cload wouldn't work.

If i write a script to write to the card block by block with the eml dump, (telling the script which key to use for each block written) would this work?
