I have recently tried to install the new b9s and luma 8.0. But I made a big mistake, I installed Luma first and wrote it directly to the CTRnand. After this the N3DS didn't want to boot anymore, it just flashes about one second with the blue led in the typical glowing effect. Just moving a old luma boot.firm to the SD's root doesn't work. How can I update b9s now or downgrade luma again to get my NDS booting. Would a Hardmod help?
