I had to switch my memory card and tried to just copy and paste all the files from the old to the new. I have luma 8.1 installed and a few games. The system starts up just fine, I can enter god mode, and open homebrew launcher however if I try and run a game I get an exemption error now. Would this be due to switching memory cards? My ultimate goal is to return my system to stock. I have tried to use this guide,https://3ds.guide/uninstall-cfw.html , however I get an error when I try to run the uninstall script. Any help, including redirect to potential duplicate post, would be greatly appreciated.
