I asked myself the question, if I jailbreak the Nintendo Switch and play everything in offline mode, nothing can happen, but when I go online again, I switch off the jailbreak. Can I be banned if I play a normally purchased game online?
You have to be careful that the Switch really doesn't have any files left. That's why you can also make a backup before hacking so that you can restore the original state after hacking!
What do you mean by remaining data?
If you turn off the jailbreak, there may still be suspicious files in the console. Therefore you should make a backup beforehand.
YES! If you are unlucky forever!
Nintendo is very aggressive there (nothing against Nintendo)
Okay thanks. I got the new model anyway, as there are a lot of retro games on Nintendo Online now.
