    Okay so i installed atmosphere with the first release when i was on FW3.0. it was at this time i performed all the backups and put them on my computer. I never opened up the backup folder. I then updated using Choidujour to 6.1 everything was all good at this point. i then updated to Kosmos still on 6.1 took some getting used to with nogc but once i figured that out all good. but i didnt know what emummc was i just used cfwnand always. i got a new game and wanted to update to 9.1 read that atmosphere supported it so i got ChoidujourNX and proceded to update. it said it was successful i rebooted and i would get stuck at Hekate. however if i launch emummc it boots just fine into 6.1. i saved this SD card for later.i went looking for the original backups and the backup folder was empty. so i used this guide https://switch.homebrew.guide/usingcfw/manualchoiupgrade to try and go back to 6.1 on sysnand. Choidujour (on my computer CMD) keeps giving me a invalid nca header! Are keys correct? failure. does anyone have any ideas on how i can get the sysnand operational again?

    Send the lockpick rcm payload to dump all your keys.

    If you are still getting error you may not be following directions correctly.

    You updated Hekate to the latest release? Maybe that's why you couldn't boot to 9.1.0.
