Hacking Question sysnand restore? sysnand cfw question using atmosphere.

[Wombo Combo]

I had SXOS va emunand and had a backup of boot0, boot1, keys.txt and rawnand.bin using SXOS software. I recently used a different SD card and installed Atmosphere directly on the sd card exfat and updated the firmware 12.1.0. I didnt realize it was using CFW on sysnand by simpling copying to SD card I installed some nsps (dont care about switch being banned). Would I be able to resture the stock firmware again even its a lower firmware like 6.0 or something if something goes wrong and my switch gets bricked. What can I do to make it less likely to get bricked should I make a emunand of the cfw sysnand and used that? I havent done this in a while and a little lost any advice would be appreciated. Thanks.

Good idea to check out your fuse count, knowing specific firmware the backup was made would be good, lower firmware on higher fuse count you might get an unbootable unit.

I looked and it says 7 fuses 6.0.0-6.1.0

That was what firmware I was on when I backed up so would it be safe to restore to that?

If you have boot0/boot1 and rawnand you can downgrade back to what you were before.

Even if the firmware and the fuses didn't match, you can just enable AutoRCM after you restore your eMMC backup to bypass the fuse check with Fusee Gelee.
