So I need a small favour from someone who's not yet registered a NNID on their 3DS... Basically, I ended up using my main NNID on my 3DS and a temporary one on my Wii U (for reasons I'll not go into here). I've now decided that I want to delete the temporary one on my Wii U and just use my main NNID on both systems. The problem here is that only options on the Wii U are; Delete the user account and leave the NNID intact Delete the user account and the NNID There's no option to just delete the NNID, which would unfortunately mean I'd lose all my savegames. The 3DS however does have this option. You can delete a NNID without affecting the system/account/savegames. This also apparently deletes the NNID from any other systems you've registered it to, so in my case, the Wii U. Supposedly, some time after deleting the NNID the Wii U will throw up an error that it's been deleted and you can relink a different ID to the machine. This is where I require assistance. I need someone with a 3DS to set up my NNID on their system, then immediately delete it. This should delete the NNID from Nintendo's servers and also my Wii U. Like I said, it's only a temporary account - there's no info on there that's relevant/important, nor is there any saved CC info or purchases; temporary account, temporary email address and made-up user details. I'd do it myself but as my 3DS currently has the NNID I want to keep, I'd have to delete it in order to set up the temporary one for deletion. I had the bright idea that maybe I could do it myself in sysNAND, but unfortunately I've downgraded my sysNAND's MSET, so there's no option to even set up a NNID. If anyone can help me out with this I'd greatly appreciate it. Get in touch and I'll PM the account details... I know it's a long-winded way of doing it, but it's the only thing I can think of that might work.
