I’m hoping to gain (and share) some clarity here, as I’ve struggled to grasp some concepts around firmware updates, when it comes to Mariko.
I’ve a Mariko switch with SX Core, running SXOS on EmuNAND.
I am on OFW 10.1 and created EmuNAND from that (backed up multiple times).
I now need to update to 10.2 to run a certain piece of software.
Here’s what I’m unclear about:
1) If I only update the CFW to 10.2 via ChoiDUjourNX, then surely that’s a massive red flag to Ninty when I then boot 10.1 OFW as there’ll be a fuse mismatch? I’m assuming here that fuses are always blown on a FW update as you cannot select “do not blow fuses” in ChoiDuJourNX on Mariko units?
2) If I update OFW to 10.2, then my fuse count will be higher than my EmuNAND backup, so do I then need to do a whole new backup (I’m assuming I cannot restore an older CFW than the Fuse count expects and so my CFW backup becomes unusable every time I update OFW)?
I suspect I’ve mis-assumed at least one piece of information, but I’m just not clear from what I’ve read (mostly because I’m Mariko).
Thanks !
