    Please help, so nintendo switch is force updating my 8.1.0 to the new version to play the new games. I couldnt find cfw 9.0 so what I did was downgrade using choidujourNX to 7.0 so my switch did downgrade I boot up atmosphere it gives an error saying I am in a wrong atmosphere version. So I googled the compatible one for 7.0 and so I downloaded installed atmosphere 0.8.4. So now I would think it would work But then it goes back to the error message. Now my switch is stuck to this because I cant access atmosphere to use choidujournx to return to my old firmware of the new one. I dont know what to do I am fairly new to this PLEASE Help experts. I use a dongle is of usb payload.

    PICTURE OF ERROR CODE DOWN BELOW

    thanks guys

    I gues on earth.
    1. Ams already supports 9.0.0
    2. Downgrading won't solve anything.
    3. Can you boot OFW?

    I know I just didnt know how to update the firmware 9.0 I was so eager to play games and just wanted to try it. it ended being stupid. like how do go back to my old firmware to upgrade to the firmware now because the Choidujournx is inside the switch. Is there a way around it using my deskstop or another way?

    Have you tried deleting your themes from your sd card and boot up?

    Easiest way around is to use new SD card and just get atmosphere and choidujiournx and update to 8.1.0.

    Yes I can do that but the switch is stuck on 7.0 n it won’t load that’s the problem I can’t get it to start because now the switch is on 7.0 but it won’t load neither the compatible atmosphere... is there way thru this like a choidujournyx thru a desktop?

    Erm...Go to system settings, scroll down to the latest option called "Console" or whatever it is called in english, and click/tap on the first sub-option. Very easy right?

    its your themes that’s causing your issues have you deleted both folders from .../titles/..1000 & ...1013. Have you updated to the latest Kosmos package I presume your using Kosmos.

    Edit: also can you boot into official firmware?

    If known of this helps, it looks like you have downgraded to a firmware you have already blown fuses your only option is too update official firmware to 9.0 grab the latest Kosmos package and continue from there in cfw.

    I did delete themes and the ATS error went away but then there is a nintendo error in black background white words its unable to load up FW 7.0 ..... well I am using AMS and Choidujournyx to downgrade. If i use the choi isnt not burning any fuses which exactly what i did. or I did burnt my fuse thats y its not working? how would kosmos help I did download kosmos on AMS but I didnt load it. Yes how would update it to FW 9.0 if it doesnt load up thats what I am worried I cant boot my switch to turn on homepage. How can I use kosmos when my switch wont boot to the page?

    I think you downgraded with ChoiDujournx to a firmware beyond your fuse count this is why your getting the error. If you take your sd card out boot into ofw like you would normally update it to 9.0 put the latest Kosmos package back on and run cfw on 9.0 that’s your only option unless someone else knows better? Tbh I have never done this so I’m not the upmost expert on downgrading over a fuse count I’m just assuming this is your option to take.

    Same here bro I’m new to this I didn’t know I burnt all my fuses I should back everything up first. But I just recently got into this but b4 I was actually updating my switch from June 2018 till 8.1 fw so that means I have burnt it all I guess? So running cosmos can restore or update it to 9.0 the switch itself?? I will read about it more thank u. What I was thinking was upgrading it through a deskstop
    Would that work?

    This is just outright wrong and backwards. Fuse count only matters when booting OFW, CFW/Hekate all bypass the fuse count, can boot 1.0.0 with fuses blown for 9.0.0 with cfw.

    --------------------

    I would completely remove the atmosphere directory (rename it) and copy the latest kosmos to your sdcard and try to boot.

    If you still get the error after that, the downgrade likely went poorly. In that case you need to manually do the downgrade as outlined here;
    https://switch.homebrew.guide/usingcfw/manualchoiupgrade
    It looks like a lot, but it's just very verbose, lots of info, not actually a bunch of work. Follow it to the letter!

    With that method you'll be installing 6.1.0 (the page says upgrade, but it can also downgrade), and then updating with choinx to whatever you want.

    Sounds like something went wrong with the downgrade. If you removed the previous Atmosphere folder and put Kosmos on your sdcard it should have booted fine. I would follow the guide I linked or restore a nand backup if you have one.

    Hey buddy yes I saw like o man kosmos three cfw that should of work but it started ams then it blacked out just charging icon so weird. So now my only option is to follow that link u sent which contain upgrading it manually with a deskstop I will do it tonight this one should forsure work right?

    I actually don’t have a nand backup I’m new to this I was dumb I just copy paste the file into a folder in comp with no clue that nand is a backup in case things go wrong?

    Thanks friend
