Okay, after following the guide I think something's wrong. All was good. My 3DS booted with my EmuNand content. I formatted the SD to delete the EmuNand partition. Now, with SD it sticks in a black screen, if I press START, Hourglass. If I press SELECT, I have Luma and if I press other button, it just boots like it was on SysNand: no theme, no content, only DSIWare. I have unlinked NANDs, if this had something to do with. What can I do? Reinstalling EmuNAND? Restore backups again?
