Help With Removing Jailbreak nintendo switch

[Albert4252]

I just bought a nintendo switch from a friend, is there a way to remove the jailbreak? or am i stuck with it?

 

[Plazorn]

Please elaborate: what is the switch model? Does it have a mod chip? What happens when you remove the sd card and reboot? Why would you want to remove the custom firmware?

Ask if he was banned or not.
If he was banned then you're out of luck, you can't unban the device.
If he wasn't banned, you need to disable the Autorcm (on a unpatched switch without a modchip).
Then you need Haku33 to completely wipe all traces because a factory reset isn't enough.

After that you're good to go online.
But you could also consider preparing an emummc again for offline *cough* homebrew and keep your sysnand clean for online gaming with carts you legally own.
