    Could this USB-port be used to restore a bricked 3DS?

    Only if you're using a Raspberry Pi method to forcefully erase the NAND. Of course you need a working backup of your NAND (extracted before the brick).

    Complementing our posts (mine and krisztian1997), this USB port only uses 4 wires, which is exactly the amount of wires the Raspberry uses. To use the Arduino method you'll need a 5th one (DAT3).

    Cheers!

    the port uses 5 pins but you need a cable that has 5 wires which is pretty rare.

    Couldn't you use the "GND" one (the one twisted)? ;)
    This way you'd have a 5th cable.

    Cheers!

    Do you know what did the guy use the twisted cable for?

    If guess that since the cable is thicker than the other and don't have "insulation" (nothing covering it, if you use the cable for data related signals, it will suffer alterations or something. isn't it?
    What if you try to use it for GND?

    He used it for the GND, using it for data would be retarded because the 3DS eMMC chips are super sensible, from what I read new eMMC chips hate if the clocks rising and falling edge are not squareish

    Right! Then we're doomed and this 4 wires micro USB won't work with Arduino natively :)

    Cheers!

    Could you please post screenshots of aliak11's work when he sends it back and if there was any cost, etc? I was considering getting this mod and it would be nice to have feedback... call it a costumer review I suppose. :P I mean with the permission of aliak11 of course.
