My bootctr9 was working just fine this morning till I updated it due to the fact that I thought I may need to update for pokemon sun and moon. After words my bootctr9 stopped working after even re-adding it to my sd card. I can't reboot into luma 6.7. Does anyone know how I may access my gateway while on luma? ALSO: I used https://gbatemp.net/threads/tutorial-using-luma3ds-with-gateway-on-v2-a9lh.431691/ this but all I got was to the boot menu and it appearing when I press down. It still doesn't let me use my roms from my micro sd card when I press select.
