Hacking Kosmos accidental emunand update unknown pkg1 version

[netster]

Hey peeps,

I just accidentally hit yes on one of the hundreds of update nags and it updated my emunand.

Now when loading up kosmos i get the below error message.

"unknown pkg1 version
Is emmc corrupt?
Or not yet supported HOS Version!
Failed to launch HOS!
Press Any key..."

Any ideas where to go from there?

The problem is your CFW is out of date. Kosmos has been discontinued, so it is recommended that you remove it and instead use the latest Atmosphere and fusee-primary.

Is there a way to replace Kosmos with Atmosphere and fusee-primary with my current emunand setup or will i have to set all that up again?

Yes. Do the following:

1. Make a NAND backup with Hekate if you haven't already. Make sure you at least backup eMMC SYS and BOOT0/1. Store it somewhere safe.
2. Make sure your SD card is formatted as FAT32. If it isn't use guiformat to reformat it as FAT32.
3. Remove all CFW files/folders from your SD card (that would be folders like /sept/ and /atmosphere/)
4. Download the latest Atmosphere
5. Download the latest fusee-primary (next to Atmosphere)
6. Download these signature patches
7. Put Atmosphere and the signature patches onto your SD card. Overwrite anything that asks to be overwritten.
8. Put the SD into your Switch
9. Launch Atmosphere using fusee-primary

It should automatically boot your emuNAND. If it doesn't, make sure you have "emummc/emummc.ini" on your SD card, and make sure it says emummc!enabled as a config entry.
