I have a launch Switch. I used it online briefly when I first got it, but I then kept it offline in the interest of a potential coldboot exploit.

When hacks became available, I created an emunand and have barely touched sysnand since then. I have homebrew and hacking on emunand, but have never run any homebrew apps on sysnand. Both kept offline.

I want to reconnect to the internet on sysnand, update to the latest firmware, and play games I've bought physically online. I'm worried about my sysnand potentially being flagged for a ban.

In the past, I've unintentionally had my Hekate launch settings overwritten, and accidently launched into sysnand with CFW enabled. It booted back into sysnand, and I immediately shut down and did nothing homebrew related. Even so, I'm not sure what those Hekate settings actually did, and if the sysnand would have changes or logs that would flag a ban.

I plan to:
- remove the microsd card with everything emunand related
- factory reset on sysnand to completely wipe everything
- on sysnand, connect to the internet
- confirm there's no ban by accessing the eshop
- log back into my Nintendo account
- reinsert microsd card, continue to use emunand for offline play

Does that sound correct? If there was anything flagged on sysnand, will doing this system restore fix things?

Most likely, I'm 90% sure your sysnand is already BANNED for online use (including eshop).
I have (2) launch Switches that were online briefly just to link my nintendo ids.
After 2 years passed, I was just curious and went online to check the eshop. And guess what? yep I am BANNED.

Only way to find out is to go online yourself and see if you can access the eshop.

I went online in SX OS by mistake and did not play, run, install any games or homebrew there about two years ago. Not banned yet, but you never know.

There is no way to "clean" a sysnand and go online without a Ban, because The Big N saves your logs and states on their servers, so if you connect a system with the same ID and different logs that is a instant ban, and is impossible to leave your system on the exact state it was when connected last time.

you could restore the backup of your sysnand before you hacked it and it should make it "clean" that's what i did when i switched to emunand so my sysnand has always been clean and i'm still not banned. I play online every so often

no guarantee tho

I think you misunderstand the situation. My Switch hasn't been online since I started hacking it. The logs on Nintendo's servers are all normal. All hacking has been confined to my offline emunand.

I want to know if my accidental CFW sysnand access will cause a ban.

Good to know. I use atmosphere, so I hope it works the same.

I do have that backup. My question is, is the nand restore necessary? I'm not sure if sysnand cfw would leave logs that could lead to a ban.

lmao what? "most likely"? where did you get this from.. 1000s of people. including myself play online in syscfw, use homebrew and even cheats and arent banned and havent been in 3+yrs.

If all op did was boot syscfw then shutdown, he 99.9% wont ever get banned.

oh lol



I haven't configured it. So that's a no then?
if you never had the switch connected to internet at all in emunand, that itself is basically exosphere. that said, you had better incognito/exosphere just incase you accidentally do connect. so even tho you didnt have exosphere, so long as you never connected to the internet in that nand, then nintendo wont have any logs.

all you need to do is:

1: exosphere/incognito your emunand.
2: shutdown then boot ofw.
3: update ofw and play like normal.

no need to keep sd out while in ofw, nintendo cant ban you for whats on your sd card.

So is it safe if I play a 60fps patch on syscfw while the switch is offline and after rebooting play that game online without patches/hacks? And is it safe if I (for example) play Breath of the wild with overclock while the switch is connected to the internet since botw is not an online game?

Single player games is fine whether your switch is online or not. But to prevent being paranoid about what isn't safe setup an emunand and do your cfw stuff on that instead. Thats your best future proof ban solution.

nothing in syscfw is "Safe" only varying degrees of it, that said. sysclk is fine even online. mods vary from game to game. botw any mod youre likely fine. whether the game is online of not doesnt matter. the switch holds logs that it sends once you reconnect. so staying offline for certain mods doesnt do anything if you go back online in that same nand.

Yeah but he didnt say anything about going online with it, and even then, ive seen a bunch of peoplesz using mods to use giga bowser online in smash, its been months and ive still seen the same guy, now that was a few years back, but unless nintendos ban waves take longer than months, i doubt hes been banned, especially if hes done nothing online-wise, and as for hekate messing with the sysnand, that also idk and should probably ask to the devszh instead or on their discordszh i guess.

I can only speak from personal experience but I have a switch that I used sysNAND CFW offline on for a long time. As an experiment I restored my "clean" NAND backup and ran sysNAND CFW connecting online to update and log into eShop to download games. No issues. I have ran it overclocked, I have ran other homebrew titles, I've used JKSV and edited saves, I've ran a couple mods in BOTW, I have also used chaiki and moonlight online by blocking the DNS. I've later turned off the blocked DNS and I can report that the switch is still not banned. Granted I have not installed anything to it as far as game backups go which I know is an insta-ban (a friend of mine did just that), I don't even have sig patches installed. Everything has been fine.

Now, while I haven't tried it myself, I know some streamers who have played MK8 online with character swap mods enabled and have not been banned. There's also animal crossing treasure island streams on twitch that use CFW, the mobile spawner, and bots to let viewers inject items into the streamers game island so they can visit them to claim on thier unmodded islands. Afaik they have avoided bans.

Moral of the story tho, it seems certain homebrew are "safer than others". My theory is if it isnt something system altering like edited profile pics, unsigned game installs, or massive game changing mods that'll affect other players then they typically go unnoticed. In the case of the MK8 streamer he's only replacing game models/sounds, they don't affect other players models and only he can see the changes.

That said do these at your own risk, just because I've gotten away with things doesn't mean you will. If you're planning to go fully legit and you have a clean NAND backup to restore to before you connect online, I'd say you'll likely be ok. Even without a clean NAND backup if you haven't touched online with cfw, a factory reset may be all you need before you connect to the internet to be safe from ban. All I can say is, you're already not using the network anyways, worst case scenario you get banned and you still don't use the network... Even then with a ban you should still be able to use wifi with homebrew software so not a total loss. I wish you luck, tho!
