I bought a refurbished 2DS XL off the Gamestop website last year. I also got an R4 SDHC GOLD Pro 2020 flashcard. I updated my device yesterday and now it gives me an error that says ARM11 (core 1). I never jailbroke/hacked my ds or anything, the closest thing I ever did to anything like that was using the R4 card. When it used to work properly, the screen said it was a 3DS which I always thought was odd but ignored it, not sure if that matters. When I press and hold Power + Select, it gives me a Luma 3DS v10.0.1 configuration menu. I'm not too sure what that or the issue is. Can someone please help me fix this?
