I recently got permabanned on my NNID from playing Pokemon Sun/Moon early, and to prevent the chance of getting a ban on my NNID itself since I am still able to use it elsewhere, I am trying to unlink it from my 3ds and link a new NNID until there are better methods to circumvent the 022-2812 error. Currently my 3ds doesn't have an NNID from injecting a blank nnidsave, but when I try to create a new NNID I get an Error 022-2452. My 3ds is using the arm9loaderhax.bin that is able to get around the 022-2812 error for now.
