Hello, I have an old 3ds in 10.5.0-30E under emunand rxtool, put in January 2016. I would like to pass it in Luma 3DS because gba games give black screens. But all the tutorial that I find are for the 3ds in original firmware, not flash.. So i don't know what to do with this 3ds which is already in cfw... Would you have a method / tutorial for a 3ds already in this firmware? Thank you. Sorry for my English, I use a translator.
