    My New 3DS all of a sudden won't boot from my SD with Luma3DS and b9s installed.
    The screen just stays black and i hear no sound, not even the typical sound when the screens turn on.
    I tried booting it without the SD and it works. But if i put it back in i cant even go to luma chainloader or it's config.
    I also tested the SD with h2testw but it didn't find any errors. What should I do now, help?

    Show content of your SD card.

    You can try replacing the boot.firm with a new copy of boot.firm from 9.1 Luma3DS.

    It looks like somehow you lost CFW, if you can't get into Luma Configuration menu or the Chainloader menu.

    You can try backing up all the file off the other card, then format the card again see if that help.

    SD cards are great (if real) but still dont last forever. Maybe yours has just reached its end?

    Check if your card's fake with H2testw in a Full Write + Verify Test when it's empty.

    Try booting with a different SD card with a test custom firmware setup. Look here for a quick build. If that doesn't work either, what model 3DS do you have?

    You may be looking at a replacement SD reader.

    Edit - If the temporary CFW with a new Nintendo 3DS folder works, try these on your main setup.

    Wow, I'm not on top of things today. Sorry, I didn't read or follow the previous posts.

    Here's what you can try on your troublesome card.

    Reformat the card with this first:
    Reformat it again with this:
    Check that card again with a test setup.

    Edit - I would personally retire the card if it derped on you before. Take it as a good sign that it was warning you its time has come.

    Files can get corrupted on an sd card without you doing anything. I'm guessing that's what happened here. Happened on my PSP recently.

    Weird thing is after a format and reinstalling the files it's working fine again.

    It's never a bad idea to keep all your files backed up on your PC in case something like this happens again. I even back up my saves.
