Atmosphere error Unknown pkg1 version

try booting stock with hekate 5.5.2 see if that works
to make sure your downgrade was success and you didnt mess up your sysnand but from what i know you should Not use
ChoiDujourNX on Sysnand on Mariko cause it bricks the cosnole you should've used Daybreak that comes with atmosphere
maybe little bit more reading before doing anything like that next time will be good
if you cant boot stock with hekate 5.5.2 then your sysnand is bad and it needs rebuilding look into that

 

Is it a freshly formatted card?

I had this problem where my card got converted to a GPT file system which wouldn't work on my switch even with the correct files placed

I had to format it again and change it from GPT to MBR and it worked straight away

 

you need DRM free firmware for SX Mod Chip called "Spacecraft-NX" to run Atmosphere on Mariko consoles type in google "Spacecraft-NX github" download it and read the instructions on how to install it on your mod chip then you can use hekate and Atmosphere you need to read on that how to use them you will need the Mariko keys for hekate all that info is easily accessible with a simple google search
then if you want to downgrade dont use ChoidujourNX use Daybreak it comes woth Atmosphere ChoidujourNX is old and ppl have issues downgrading with it
but the safety option for Mariko consoles on 11.0.1 is to just use Atmosphere and dont downgrade

 

Always used Choi without problems, is the wrong answer. Using Choi on a Mariko system to update to 11.0.1 gets you a boot0 with erista data in it. Basically a softbrick. You need a donor boot0/boot1 from a working mariko unit on the same firmware as you. I’ve read several other posts just today with the same issue and this is the answer that’s given. This is on top of needing spacecraft-nx.

 

Do a new emmummc dump using hekate and copy the boot0 and boot1 from it over (assuming you didn't update your sysnand using choidujournx)

You don't need spacecraft nx to run hekate/atmosphere. you just need to patch the boot.dat with the sxgear 1.1 one and your mariko console will boot into the hekate

 

Hello friend, I have the same problem, the same thing happened to me when doing the update, could you teach me to repair it or mr purdr pass the boot0 please

 

Can you please walk us through step by step how you did that?
I have a boot0.bin donor too.
What folders do you put them in and how to do you launch them?

Can you post screenshots of your SD card folders showing us how/where to place the files needed?
And then tell us if you launched hetake (and what version) to get into Atmosphere (and what version).
Then what buttons you pushed on the hetake interface to launch Atmosphere?

Just like a lot more detail so others can try it please.

For example, in SXOS when you create a backup it puts the boot0, boot1, and raw stuff on a backup folder in the sxos folder thats on the root of the SD.
So, when we restore a NAND do we put boot0 and boot1 in that same folder?
Do we need the rawnand?
Does it matter if the rawnand was created with a bad boot0 boot1?

 

hi i have the same problem like you please can you share boot0.bin donor? please

 

You can just make your own with either eMMChacgen or ChoiDujour
