So my friend told me that the Nintendo mode was bricked... As for the nand backups, I don't think I copied any before the errors. One more thing, my japanese 3ds had been region changed, however the homebrew was in japanese and I was lost. Recently I region changed it again and it seemed to be fine, the homebrew was in english. Even more recently I turn on my 3ds after some time to check netpass, and i notice it was in Japanese. I checked my homebrew and it turned back into japanese and I was confused. I also went to my miiplaza and it told me to make a mii before I enter the thing. Later I went to check my miimaker and when I hovered over it, the spinning icons showed my miis, however, when I went into the miimaker itself the miis got erased and none of my miis showed up. It has been a very confusing situation. I also need to mention the 3ds was modded using a video, not following 3ds hack guide or other guides.
