Hacking Question Clean User Backup

[OnHaDe]

My old eMMC died. Luckily I was able to dump all partitions (except USER) and the prod.keys beforehand.
I got a new eMMC, but was unable to get its keys for some reason (probably wiped or something).
Now my problem is that I need a clean unencrypted USER backup, so I can restore my old eMMC backup. eMMCHaccGen generates a folder for USER that you are supposed to paste into USER after mounting it, but since I don't have the bis keys of the new eMMC I can't mount the partition.
Is there some way to generate a USER backup or do I need to get an unencrypted USER backup from someone else?

I bet. Interestingly what killed the chip was a factory reset of the switch. Initially I was not able to create a full backup because a part of the nand seemed to be broken, so I backed up everything I could and after trying a bunch of other things I did a hard reset which killed the chip completely.
