I've seen this asked elsewhere, but the answers I've seen don't make sense, so I figure the noob area would be appropriate.
Before I hacked my switch, I was a good boy and did a full backup. This was in Jan of 2018. The latest firmware was 4.x at that date, however I know I've updated the switch since then. The burnt fuses count shows 6, which I think means I had updated to 5.x.
Since there's now an emuMMC option where we can toggle between CFW and OFW, what I'd like to do is restore my backup so I'm back to a pristine OFW state and then set up emuMMC, however I understand that if I restore my backup, it's going to put a 4.x version of the OFW that isn't going to like the 5.x fuse burn count.
The trick I can't figure out is how to get the appropriate 5.x firmware version installed after restoring. The solutions I've read all bring up using ChoiDujourNX for this, however, I thought the switch had to be hacked to use that -- exactly what I'm trying to avoid. Is it possible to do this? Perhaps editing the backup to "inject" the 5.x firmware?
