A friend of mine recently did a9lh and everything went fine. Today he made a .cia of a game and downloaded Save Data Manager https://gbatemp.net/threads/release-jks-savemanager-homebrew-cia-save-manager.413143/ then after that his 2DS wouldn't start. Blue led and black screen. He tried troubleshooting by formatting his SD and loading a backup made while following Plialect but with no avail. Still black screen. The fuck happened? Thanks.
