Maybe its referring to the modifications EmuNAND makes to boot1 rendering booting OFW impossible on 4.1 and below? As I stated previously, I don't have a license to test this but it seems like a rather simple thing to test. Just boot 2.4, setup EmuNAND but don't enable AutoRCM, turn off the console, and try booting OFW without SX OS. Even if it black screens, you can get out of it with a manual shutdown (holding power for 12 seconds).
If you update to 6.2 now, you will burn fuses and it will be impossible for you to downgrade in case a future exploit (like untethered coldboot) comes out on a lower firmware. If you don't care about downgrading or other potential exploits, you can just burn fuses and update normally right now. If you do care, wait until you get the SX Pro then use the homebrew application ChoiDujourNX to update to whatever firmware you want.
Honestly never heard of this issue. Maybe try booting a newer version of Atmosphere? It is up to 0.8.2 now. If you haven't tried this package already, you can try loading Kosmos which is Atmosphere but with Hekate instead of Fusee.
4NXCI is based off of Hactool which hasn't been updated with most of the newer keys so it just freaks out and spits a lot of warnings but at the end of the day, that's all they are, warnings.
Sounds like they require a game update because a system update would say a system update is required.
Different programs use differently formatted key files for whatever reason. You can just rename the prod.keys file to whatever you want like keys.txt if the program you are using requires such.
I’m not sure mate if I test things out il brick is there any testers in gbatemp could check? they also said see below
Team Xecuter has put out a post on their forums which says that their 2.4 doesn't work with ofw 4.1.0 and below. Also they have said that on 2.4 you can't boot other payloads (so ox will freeze if you choose this option) so for your first step you'd need to find another way to push hekate to your switch.
As far as I know, SX OS 2.3 can push henkate and create emuNAND (sort of, but i don't pretend to go online right now anyway, so this kind of emuNAND works just fine).
So i'll have a emunand on 6.2 and my OFW on 4.1.0 without burned fuses.
