I got to Christmas a Samsung MicroSDXC 128GB EVO Plus UHS-I Grade 1 Class 10 . Before i downgraded my 3ds i tried it and it doesn't work with my data. I inserted it without any folders in it, started the 3ds and it worked. Then I started the homebrew launcher (Freakyhax) and tried to install a game from fbi (and waithax). When i started to install the game the 3ds said i ejected my sd and it reboots now. My Question is how to use the sd without problems on my 3dsXL without loosing my data and how can I install games on it when it "ejects" itself?
