I made a chargeback on a purchase from the eShop. Nintendo locked my 3DS, blocking my NNID from formatting, updating games(cant play any games online), or deleting the NNID from the system settings. Any time I try to do one of these things I am hit with Error Code 005-5964. I can still use the web browser to full effect. I did some searching on the forums and found this: "If you can run rxTools, then I believe there is a way to remove the NNID by deleting a file from NAND. Delete these folders : nand:/data/<ID0>/sysdata/00010032 nand:/data/<ID0>/sysdata/00010038 nand:/data/<ID0>/sysdata/0002009F nand:/data/<ID0>/sysdata/000202C1 You will probably have to dump the NAND and the xorpads for it (using rxTools) to do that." So from what I've gathered, I need to downgrade from 10.7 to 9.2 (which I think requires a hackable game? I have Smash 3ds from the eshop V1.08) and then install rxTools as well as a program called gateway onto my 3ds. I just do not know where to start.
