    Would/has it been possible to dump and decrypt the bootrom without a devkit?

    EDIT: A devkit isn't essential?

    There are a number of theoretical methods for dumping bootrom. One way we know we can do it is decapping, but this is extremely expensive.

    A devkit wouldn't help dumping the bootrom afaik.

    It would be very useful, though. In general.

    well, i think that it's pretty obvius we need to dump the boot rom when the 3ds is completely shutted down

    Not really possible given that file IO isn't active then. Even making a NAND dump from a hardmod requires turning the 3ds on.

    then we need another method. because the bootrom already locked himself once booted.

    Read here: https://www.3dbrew.org/wiki/3DS_System_Flaws

    Specifically, the "ARM9/ARM11 bootrom vectors point at unitialized RAM" section. That's the best bet we have right now.

    PS3s can have a wire soldered to the board, which keeps the system at a point where when switched on a NOR backup can be restored (idk if this useful though)

    That probably wouldn't go over well with people, considering the last time the 3DS community tried to do this, the organiser ran off with over $2000, iirc.

    Welp, Ive only been in the scene half a year...
    Maybe if we got someone well trusted and well informed on the subject to organize it things would go better?

    If I recall, the organiser was someone who was trusted, and still made off with it. That's not to say a trustworthy figure couldn't arise to take the reins this time, but you can certainly see why people would be reluctant.
