So, I have used the unbanning method for MiiVerse (because I am a user of MiiVerse Custom Image Tool). I kept a backup of my nnidsave.bin, and now I am trying to use my old NNID, which is contained in nnidsave.bin. But, not only can I not access my old NNID, I can't even access the eShop with a brand new one. No matter what I always get the same error code. I have A9LH without emuNAND, my sysNAND is on 10.7. My main question is: Is there a way to still access the eShop, even if it means sacrificing my old NNID?
