So I was attempting to downgrade my o3DS, I think sysupdater froze after I hit the Y button to downgrade. All I saw was a single line of incomplete text. I waited for about 20min, nothing changed. Powered off the 3ds and restarted, out of curiosity I went to check the system setting app an I got hit with a "An error has occuured" message everytime I try to open it. I can still launch Homebrew, and other apps still load fine. I tried to boot into safe mode, but that does not work, I just get a black screen with safe mode. What can I do?
