I've recently bought a used Switch that came with SX Pro and OS. The previous owner was not very tech savvy, and never messed around with anything but playing backups in the console (but never went online).
I've read that pretty much everything you play and do in the console is logged and sent to the Nintendo Servers whevener you go online, and since the previous owner never set up a Emunand or backed up the NAND, I don't think I can go online without getting the console banned.
My question is: If I want to buy a legit game and play online, is there a way to remove said logs (like a factory reset) and set up the emunand?
