    Could I update from 1.0 to 5.1, then be able to downgrade?

    You can, not sure exactly how it works with TX os though. Use rajkostos method, be aware that you will burn a cartridge slot fuse, making it unusable on firmware below 4.0.0.

    SX OS 1.1 added fuse protection I believe

    I'm stuck in the same situation, I decided to just update to 4.1 with tropical storm so I get better game comparability/fix SDXC update prompt and still have Fusée Gelée working for atmosphere in the future.

    Did you update with a real cartridge of tropical storm or dump?

    Im gonna get a cartridge at gamestop and return it after updating since I cant get anything larger than 4 Gigs onto the SD card because my switch wants to update for exfat support even though its on 2.2.

    If it's just exfat support you are after then I recommend this guide
    https://gbatemp.net/threads/how-to-...tch-console-on-any-ofw-without-update.505182/
    I followed it and added exfat support to my 4.0.1 switch.

    So, concerning that long rajkosto upgrade/downgrade fuse ignoring guide:

    Is there anyway I can make this easier/faster due to sx os or the dongle?
    Or anything I should look out for?
    I'm on 2.3 but will 'temporarily' update to the latest fw so I can play the latest games. Hopefully I can cold boot via 2.3 later :)

    Not really SX can't help you. It's really not that bad. Just make sure to backup nand so you know you can always go back. Read the guide several times before attempting this. Ask if you are not sure.

    assuming you backed up raw nand and boot 1 and 2 we will probably see a downgrade method from TX that ignores fuse checks, with all the money they just made and will keep making they can afford sacrificial switches .

    i'm not necessarily worried about making a mistake (although that wouldn't be good)
    but haha, the guide is 'that bad' - it's so incredibly long. (a great guide of course, but, 0% enjoyability factor)

    but yeah i'll probably do it.
    thanks :)

    You can play Mario Odyssey on 4.1, plus, you can also split *.XCI flies into 4Gb files & run them through SX OS to get around the need for exFAT support..
