    So earlier this year, I had Avalynn hardmod my 3DS to restore the firmware in case it got updated.. Sure enough, my 6 year old nephew accidentally updated it. Only problem is, I cannot find the cord/adapter Avalynn sent me in order to hook the 3DS up to the computer and restore it.

    Where can I get one of these? It was a Mini-USB plug to an SD card. Also I'm not even sure how to restore it, I have the NAND.bin but is there a specific program I use..?

    You use Win32diskimager to write the NAND.bin to the 3DS.
    It'll ask you to format the disk once you plug it in but if you do it'll just erase the nand. So say No when it asks, and then just write the nand backup with win32diskimager

    Said cable is a custom-made cable and I don't think they could be found anywhere. You have to get a mini USB cable and modify it to solder the wires to certain specific pins on a microSD to SD adapter. Someone else may be able to point you to a guide on making your own (requires fairly precise soldering), or maybe someone sells them here.

    Since you'll need to make your own cable... Here's some info you may need
    Since you bought it from Avalynn, She detailed her micro usb connector pinout in there... (i made it red)

    Anyway, you'll either need to make your own... Or pay someone to make one for you
    The red highlighting is how she probably wired her connector.. You'll essentially need to make the same thing..
    You can use an SD adapter (which is small and difficult to solder to if you don't have experience, or something like this: https://www.sparkfun.com/products/11468 and just solder to the nice holes on that thing...

    He will need a 5 wire micro USB cable for that pinout to work. Most USB cables are 4 wires, and do not use ID.

    So I bought a custom cable from LameNobody, however when I plug it up to my PC and boot the 3DS, nothing happens. How do I get it to recognize?

    I hope you didn't plug the 3ds straight into the PC with a usb wire. :P

    It's a custom cable which plugs into the SD slot. It's not a normal microSD cable.
    Edit: I get this error message

    That looks about right, actually. While it's hanging on that screen, your computer should ask you if you want to format your 3DS, to which you should say NO.

    If it's not doing anything at all, you need to get yourself one of these: http://www.amazon.com/AnkerĀ®-Reader-RS-MMC-Support-Warranty/dp/B006T9B6R2

    Use WinDisk32Imager to "Read" the drive and let it dump your NAND.bin. Report the filesize of the NAND.bin you dumped before you attempt to write anything to the NAND: you need to make sure the connection is truly functional. (By the way, what model is that 3DS? XL, N3DS, O3DS, 2DS, etc)

    Finally came in.... Two drives appear, windows loads, then they disappear, windows loads, etc. This happens over and over & win32disk imager doesn't detect the drives.

    What can I do?

    Try testing it out on a different computer or clean out the connection with some rubbing alcohol (not too much, use a cottonswab or something and dab it a little)

    Try turning on the 3ds after you've plugged the connection into the adapter, with the adapter connected to the computer USB port.

    My next guess is that your wires don't line up with the adapter you bought. You'd probably have to open up the 3DS and the adapter to ensure all the pins match up correctly, but that might be dangerous if you haven't messed with it before.

    EDIT: Actually, as nice as it would be to get your hardmod working, you could also try downgrading from your current firmware using the sysupdater downgrading method. Just know that you only have one chance to do it, or you'll have to resort back to getting a working hardmod.
