I was region changing my emuNAND and used the triple SD card trick. I eventually did what I wanted, changed my emuNAND to Japan. However, I eventually wanted to switch back. So I did the same steps in opposite order to try to get my other NNID/eShop working on my old emuNAND. I got error code 007-2001. I tried it on multiple emunands, different NNID's, retried the whole process again and still kept getting this. Called Nintendo and all they said was that I could send it in for repair, which is just stupid so I hung up. I would delete my NNID and retry, and I might, but if it didn't work on more than just this one I am thinking it is a different problem. Any ideas? sysnand 9.2, emunand 9.9. I can still access Wii U eShop on same account. I have looked around the forums for other help, but no success.
