    This is not released yet. This is a PoC.
    DO NOT spread misinformation, saying that some cards will or won't work
    There is no point buying flashcards right now for this, when your flashcard may be supported in the future!
    @Normmatt has created a way to unbrick via a DS Flashcard and a magnet! This will work on any 3DS on any firmware version. It will be released when the installers work properly and more flashcards are supported, to prevent lots of people from buying the same type of card. Reminder that this is not an NDS file which will work with any flashcard.
    How does this work?

    This works because of a flaw in the bootrom. Before the bootrom boots the NAND, it checks to see if Start+Select+X is held down, and if the shell is closed. If these requirements are met, it will boot, from the bootrom, an NDS cartridge. This give those cards bootrom access. You might be wondering how you'd hold down buttons while the shell is closed, and why you need a magnet. If you put a magnet in a specific spot on the 3DS, it will go into sleep mode. Using this, you can boot the NDS cartridge with the buttons held down while in sleep mode! Using a reflashable flashcard, you can flash, for example, B9S to the flashcard, and easily install it on your 3DS.
    What does this mean?

    1. Any 3DS model on any firmware can be hacked with minimal effort
    2. You can unbrick any 3DS model from any type of brick.
      - Remember, you don't need a NAND backup for this. Just do a CTRTransfer.
      - This does not apply to MCU bricks.
    3. Even consoles with fried NAND, or even the NAND chip physically removed, can use this
    This is incredibly impressive stuff, and will most likely be released soon!

    FAQ

    Q: Can Nintendo patch this?
    A: Nope! Not without a new hardware revision.

    Q: My flashcard is blocked by my firmware! Can I still use this?
    A: Yes! The flashcard blacklist is not enabled on the bootrom.

    Q: So, can this work with any flashcard?
    A: No, it is not an NDS file. The flashcard needs to be reflashable.

    Q: What flashcards have been confirmed to work at this time?
    A: One, as of now. However, more flashcards will be supported soon, so wait until you know for sure that your card doesn't work before buying a compatible one.

    Q: But this flashcard is flashable, should I buy this?
    A: No! They are working on making this compatible for more devices, please wait until it is released, your flashcard might be compatible!

    Q: Will my 3DS flashcard work?
    A: No, only NDS flashcards.

    Q: When will the compatible flashcards be confirmed?
    A: Most likely when it's released.

    Q: I tried to do this with my cartridge and it didn't work?
    A: It doesn't work with regular DS cards.

    Q: When will it be released?
    A: When it's ready. Don't pester the developers for it. It'll be ready when it's ready.

    Q: Can I unbrick from a ____ brick?
    A: Considering the card has access to the bootrom, most likely yes! This can potentially unbrick any brick (except MCU), unless you've taken a knife to the motherboard.

    Q: Can I install B9S on the latest firmware with this?
    A: Again, since the card has access to the bootrom, you can potentially do this easily! Just plug in your flashcard, boot up using the magnet and button combination, and install.

    Q: Will this work on the New Nintendo 2DS XL?
    A: Probably!

    Another tidbit of info: the 2ds doesn't need a magnet since a switch (not that one, that one) puts it to sleep instead of a magnet.
    Let's wait until it's released since there's no telling when that will be.

    Most likely, however, as I stated in the OP, it will be released when more flashcards are supported to stop people buying one flashcard.

    As far as I know, it's as simple as:
    1. Put the flashcard in
    2. Boot with magnet and button combo
    3. Install B9S
    Correct me if I'm wrong, however.

    what makes a flashcard not work with this? if it runs a nds file, shouldn't it be able to run this?

    It's not an NDS file, it requires you to flash a firmware to the flashcard, which with most flashcards, is difficult.
