    Hello,

    Since all this bricking storm, I think it's time to try to recover our 3DS. Mine still working but want to talk about hat we can do to recover the machine.

    Now it seems the eMMC has been reprogrammed to a 0 byte NAND chip. So it's a no go for now to just reflash the NAND. Windows will see the 3DS as a zero byte drive.

    How can we reprogram that eMMC and then reflash the NAND using the hardware method?

    I have good soldering skill and probably can help some people nearby.

    Any expert would like to comment?

    Pitou!

    Gambia, The
    you cant write to a device that reports size zero (and seems to be toggled to read only).

    one would first need to reset the memory chips settings, which might be possible via the four wire interface used in the hardware NAND backup mod.

    Problem is, atm it's not known
    a) if this reset is possible at all (OTP area?)
    b) if it is indeed possible over the four wire interface or if you need another more sophisticated flashing interface (think infectus for example)
    c) what the exact command sequence is to reset the config.

    For that youd need drivers to access it in Linux, or at least a serial link into it. Probably be easier with a hardware nand programmer. Perhaps one of the Xbox flasher units could be repurposed for the 3ds nand chip?

    Probably wont work. 3DS have a eMMC and not a NAND

    Im not expert but if is say that the nand is interpreted as an memory, can be used the program testdisk data recovery to put new value instead 0bites? I remember than once i recover a mp3 player without format(unread by windows) cloning the size from another normal usb to my mp3 player.
