    Hey ya'll .. so I've been trying to follow this guide and make it to the part where it's time to flash the boot w etcher and etcher just will NOT recognize my switch. It shows up as the Linux named disk drive in device manager and as drive G in disk management... however etcher just won't recognize it.. Any help would be appreciated.

    EDIT:
    nevermind, weirdly enough I only had to switch the usb port I was using....

    My issues were to do with a cluttered keys file... i found the correct formatting and deleted all keys except those needed.

    Now back on 7.0.1 Atmosphere!

    Guide is actually VERY easy barring the PC side ChoiDujour part.

    I downgraded to 6.1.0 then used ChoiDujourNX to upgrade to 7.0.1. Lost saves and data as system wouldn't boot without a reset but still. DOWNGRADED FROM 8.0!!

    Hello,

    I tried to downgrade from 8.0 to 6.0.1 with the guide. Every step went well, but i can’t boot the Switch. After the Launch of FS_XXX-exfat_nocmac_nogc nothing happens. I can see some text and green text at the end. (Ok steps?) But then the screen goes black.
    What to do to solve and boot to 6.0.1

    Thanks, i will try. Can i downgrade directly from the (not working) 6.0.1 right now? Or do i have to restore my NAND backup from 8.0 first?

    Hi, sorry. I followed the guide correctly, I used the supported firmware and everything and when I launch the FS Exfat file, I get ''Initializing... Found pkg1 and Keyblob 4, Loaded pkg1 & keyblob. Then it stays like that forever.

    I tried again and now I get No Mandatory secmon or warmboot provided!
    Failed to launch firmware. I think this might be my SD card at this point?
    EDIT: nvm.

    I have successfully done this to get my switch working. How do I revert to stock and the latest FW?

    I have SX OS installed via Emunand on a 512GB SDCard hidden partition and both Emunand and Sysnand are 7.0.1, when I try and open ChoiDujourNX in homebrew launcher inside my emunand so I can update it immediately crashes back to home brew launcher screen with no errors. The gbatemp post for it does say if it crashes immediately it’s probably due to debug svc not being accessible and to update hblauncher to latest version. I downloaded and copied the latest one and put it in switch folder and open it via sx is album and try launching Choi from there but get same issue. Anyone have any ideas?

    This works for creating a clean nand?

    Is this the method most people still use to update in order to play newer games (or updates that require newer FW) assuming they don't want to blow fuses? I used it to update to 6.2 some time ago, now I feel compelled to update to 7.0.1 but don't look forward to the process.

    If you're a masochist, you can use this tool but unfortunately it doesn't support any firmware version higher than 6.2. ChoiDujourNX not only supports all firmware versions (unless Nintendo rewrites firmware installations) but it is much faster and easier to use than ChoiDujour.

    I have a clean 6.0.0 nand and boot0/1 backup which I restored but I can't boot into stock. Only booting with atmosphere works which defeats the purpose because I went back to stock to play online. I tried this guide to create new boot0/1s and a clean nand but when I enter my bis keys into hacdiskmount they fail the test. Is there anything I can do?

    It is not the fuse count. I have 6 burnt fuses which corresponds to 5.x so I should be able to boot stock 6.0.0 which I updated to without burning fuses before I went CFW.

    Edit: Figured out why my keys where failing. I wasn't using the right keys for the lower entry. Gonna try creating my blank nand again.
    Edit2: Went through with all of the partition replacements but still can't boot into stock nor atmosphere now. Need to restore my backup now.

    Edit3: I am a dumbass. This guide is for 5.1 and lower. I created a clean nand for 5.1 and it worked. Ty for this great guide. Now I gotta hope I don't get banned for updating to 6.0.0 a second time.
