Hi. My system data is formatted which logged out my nnid from my o3ds and now when I try to sign in, it says update system. But the problem here is that I have homebrew, luma 3ds and others like that. I also have version 11.3 and if I update to version 11.4, homebrew and my other applications won't work. But I need my nnid to run my sd card applications as well. Please help.
