    Hello,

    I recently upgraded my switch (without burning my fuses obviously) to 5.1.0 to update all my games.
    Can I downgrade to 4.1.0 with keeping my data? in particular the games i have purchased/loaded from eshop / updated.

    Also: Is there a way to somehow "backup" the update, so I can reinstall it manually via homebrew after setting back the console?

    Downgrading without losing data probably won't work, but why'd you want to downgrade anyway?

    Since my university starts soon, and now I got time for that. Also I want to be prepared for "Deja vu" (is there an ETA yet anyway?)

    Thanks @Wika, will look into that :)

    Downgrade your firmware to 4.1 with ChoiDujourNX. It would also be a good idea to disable installing AutoRCM when downgrading since 4.1 is your original firmware in case you do not wish to use AutoRCM.
    No.

    I believe once you have updated your games through Nintendo servers thats when eventually you will be banned.

    How can they ban me if I downgrade and then keep wifi disabled? I mean, how would they ever know I am on that firmware

    From eShop, in 5.1.0. But now I want to go back to 4.1.0 (to set everything up for Deja Vu) and disable Wifi. I mean, I cant do anything with non updated firmware anyway. So I will enter flight mode the whole time

    I really cant get your point. How can Ninty determine on which FW I am on if my switch is not connected to the internet?

    I think his point is, you needed to connect to Nintendo's servers to update your games, and that is what can get you banned. You needed to hack your console, enable autoRCM, and load a CFW to update your games on 5.1.0, and we don't know exactly if one of these actions will get you banned or not. If you haven't checked it already, @Draxzelex have an excellent thread where you can read about bans, and things you can do to lower the risk of getting banned as much as possible, among other things

    Too late for you, but for anyone else, you should really be updating your games offline using NSP updates.

    Aren't NSPs pretty much the main thing that gets most people banned? I use XCIs in CFW and then update them with OFW & eshop.

    Honestly you should 1) go permanently offline, 2) back up your NAND, 3) upgrade without burning fuses and install AutoRCM, 4) use CFW.

    If in the future you want to go online, you have the option to delete everything, downgrade, restore your old NAND which matches your OFW version and is clean because you backed it up before you did anything with CFW, go online and legit upgrade by burning fuses, and forget you ever did anything with CFW. But until then, you should remain in self imposed ban. Doing this gives you the option to end your self imposed ban when you chose. Otherwise you're going to be banned by Nintendo, and you will never have the option to end your exile.

    At this point we just don't know of a foolproof way to enjoy CFW and enjoy being online. It's really one or the other. You can take the risk, but it's a big risk. You haven't been banned yet. You may never be banned. You may wake up tomorrow and find that you have been banned for things you have already done.
