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.
