I'm not the kind of person who asks things. But his is getting me mad since I already browsed the network for several hours already, and I haven't found any clue about what's going on. So. I have a 2DS which used MenuHax for coldbooting into EmuNAND with ReiNAND. I had my eShop working, and a lot of games bought with my NNID. All working nicely. I installed arm9loaderhax using Plailect's guide. Everything went fine, and I did everything as the guide said, word by word. It works really good with Luma3DS, and it's nice to have a "bootmii" kind of in the 3DS. But. I never tried to enter the eShop since installing arm9loaderhax until today. I got the message "You cannot use this Nintendo Network ID on this System" with error code 022-2501. But it is the same NAND that I used when I had MenuHax + ReiNAND! What's the problem here? I read somewhere that this happened when messing around with Secure Info value, or something like that, when changing the console's serial. But I haven't messed up with anything like this. Just games, some emulators, and homebrew apps from time to time, I never touch anything else than that. I tried formatting the SysNAND through System Settings (backing up my NAND first, of course), and tried linking the NNID again from the formatted System Settings. It told me "The NNID was already linked to another console". Restored back my NAND backup, and everything is working fine, but I still get the same message when entering the eShop. What's going on here? Could someone please help me? Believe me, I've read everything I've seen about this. More than 20 different threads and 10 different forums. I'm right now in Updated SysNAND 11.0 (last firmware update), with Luma3DS 5.5 (latest release). Thanks in advance.
