    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?

    Define "wrote it directly to ctrnand"

    Did you install Luma directly as bootloader (confusing it with the B9S files) or still have B9S installed and just actually copied it to ctrnand for SD-less boot?

    In the second case, boot.firm from the SD should always be preferred to the one from ctrnand, weird...

    I wrote the boot.firm of luma to the root of the CTRnand and kept the old b9s installed

    Make sure boot.firm isn't corrupted. It happened to me and my 3ds kept trying to boot the outdated boot.firm on my ctrnand.

    Make sure your SD card works. Luma ALWAYS prefers boot.firm in SD card if present than in CTRNand.

    Edit: I meant B9S.

    Rename the B9S installer to boot.firm then copy it to the SD card and the 3ds will autoboot it when you power on. Upgrade B9S then Luma 8.0 will work.

    Remove the SD card after updating then if the 3ds boots Luma 8.0, copy Luma 8.0 boot.firm to the SD card root.

    Try putting SafeB9SInstaller as your boot.firm.
