Hello. I bricked my Wii U couple years ago and my Nintendo ID is still linked with that console. Is there any way to unlink it? I need that ID because I have purchased game for Haxchi. Thanx
When my 3ds broke and I bought a new one I just emailed nintendo telling them what happened and asked for my NNID to be unlinked from the broken 3ds. They repied with a few quick questions and once I answered them they unlinked the NNID. All done in under a hour.
I would imagine it would work exactly the same for the WiiU so just send them an email
You can do what @AmandaRose suggested in the thread, contact Nintendo, explain the situation to them, asks them to unlink for you, they would asks you some questions to verify the account, then they will unlink it for you.
