So, I have a 3ds that has custom firmware. I lost the sd card for it, so I got a new, clean sd card that is compatible with the 3ds. The thing is, when I hold select on boot, it still shows luma3ds. When I hold L-down-select in Download Play, it still shows the Rosalina Menu. I suspect that I still have custom firmware, so can someone please tell me how to get full cfw back (Homebrew Launcher on homescreen), or do I have to do the whole process of cfw again?
