Need Help removing NNID account off Wii U after Server Shutdown

[mrheracross214]

So to make this a long story short, I was a dumbass as a kid and for some reason made a bunch of random accounts on my Wii U, all of which I forgot the password too (except my main account and original account) I can't do the Forgot Password as i just get error code 102-2160, since the Nintendo Network servers shut down. I don't want to factory reset my Wii U as I've had it for a long time and its really nostalgic, I have Tiramisu and Aroma installed, and I can't use Pretendo since I can't make a new user on the console. Is there any way to forcibly remove the users, without resetting the console?

There is no save way. So for safety reasons the very first thing to do would be to backup all save games. After that you could try this: https://gbatemp.net/threads/deleting-wii-u-user-without-nid-password.493387/page-5#post-10192667 - Be warned that for at least two users (me included) this deleted the user account instead of unlinking it... That's why you want backups.

As you have none accessible users and stuff it might be a good idea to factory reset anyway through to get rid of the years old garbage (like these user account you can't even use). As said just backup your savegames and maybe other important stuff (like the Miis) to be able to restore them afterwards, so you won't loose much of your nostalgic feeling.
