I'm not sure where to ask this and couldn't find anyone asking, so I'll take my chances. i have a hand me down Wii U, that was modded using CBHC and has been in use for about two years like this. i have seen that there are newer mods available and wanted to know if i can start fresh. main reason i ask is because there is an account on my Wii U that we cannot delete (my cousin doesn't have access to that email address, and can't remember his Nintendo ID information) and it is basically just annoying to have that account that no one uses and that no one can delete. So, I was wanting to know if i can back up my MIIs and saves, reset the console to erase everything, and restart fresh with the newer mods. (another reason we never erased his account was because it was the one that had the CBHC compatible game)
How would I go about doing this.
