I have a quick question I can't find a clear answer to for cfw users, but I assume is true. I already have Luma 11.0 and b9s 1.4, have had cfw installed for years.
I have an o3DS and just did a sysnand backup on godmode 9 while still on firmware 11.16 (also backed up sd card). I'm about to update to 11.17. If I ever, for any reason, wanted to downgrade my o3DS sysnand firmware back to 11.16, or any other version from backups I made in godmode9, do I just follow the gm9 usage guide to restore this sysnand backup (or any previous version backup)? Would that downgrade my sysnand firmware to the previous version and work just fine?
I realize writing to sysnand can be dangerous, I'm just curious in case I ever wanted or needed to downgrade my sysnand fw, even if I don't plan on it.
Second quick question, what is the essential.exefs file for? Only asking because I don't know if it's necessary for restoring a sysnand backup, I have a few old backups that I don't see this file for. I do have this file in a few places, though, are they all the same?
