Context: Yesterday I bought a New 3DS (mostly because the ribbon cable on my O3DS is damaged, so I can still use my O3DS, but it's rather inconvenient). I am currently setting up arm9loaderhax on this 3DS. I would also like to transfer my NNID to this N3DS after I set up arm9loaderhax. The problem: As far as I'm aware there are currently two ways to unlink/transfer a NNID from a 3DS. By preforming a system transfer. I'm not too certain this is safe after I have finished setting up arm9loaderhax on an N3ds, so I'm not going to try. By formatting the System in the System Settings. This is what I want to do, but I would like to now if anyone has any tips or things that I should watch out for before I preform the reset. Last note: If there are any other known methods to unlink a NNID on a N3ds (e.g. through Homebrew), I would love to hear it.
