Hardware N3DS NAND backup possible, I hope.

Well the error code I consistently got when it was working ended in "00000200 00000000". I'm using this adapter made by Omega:

It's the exact same one I used before so I'm not sure what this means.

Then likely something loose in the custom sd card wire

I determined that the SD card reader itself is no longer working. I don't know what happened but I'll have to look into it further.

I have another issue now. I specifically ordered this SD adapter because it says in the first post that it works: SanDisk SDDR-121-A11M. But I cannot get it to work. It's the simplest wiring and I can see that there are no faults, and my multimeter confirms so. Is there anyone who's used this adapter and can describe how to use it?

Edit: I can confirm that this SanDisk SDDR-121-A11M DOES NOT work with the N3DS Toshiba eMMC. They have changed the chipset since Avalynn tested it here.

My hardmod seems to be readonly... I successfully dumped the nand, but can't restore it (1/0 Error - Failed to get lock..) How can I fix this? Is this due to the sdcard lock switch?

NVM, fixed

I created a little microUSB to USB cable for reading and writing to the NAND using the Realtek RTS5158 chipset (in the black box). I installed a microUSB port in the 3DS to go with it. I would highly recommend this to anyone who has the materials and tinkers with the NAND a lot.

Off-topc, but what's that black button on your n3ds?

It's a button that puts the 3DS into sleep mode when pressed. I made a post about it in the Console, Accessories, and Hardware section.

Interesting, I'll go check it out.

I don't know. The screwdriver I have always used for opening 3DSs came with a replacement DS Lite shell that I ordered on eBay. Maybe you can find a similar screwdriver made specifically for 3DS.

Is there a specific name for it?

Just buy a basic watch screwdriver set. It should have the size you need. The #00 is the right one

That should do. Just make sure you don't use a magnetic tip by the motherboard but it's okay for the external case screws.

Edit: The picture looked like it might be a magnetic tip but it isn't so you should be good!

Why Is Using a magnetic tips so dangerous to the motherboard?

There is the possibility that it can mess something up if the magnet is strong enough. It is very very unlikely but it is just recommended to not take the chance. I personally have used a magnetic tip plenty of times with no issues but I am not always as careful as I should be.

What did you use to cut a slot for the microusb port? I ordered the adafruit microusb b like that one...

I used a Dremel with a cutting disc to cut it, then I used a flat metal file to smooth it out.

First, that's a pretty messy solder job. Are you sure none of those wires are shorting across other traces?

Second... you really should have shown us the ground as well. It looks to me like you used ground from the power connector, and that would EXACTLY be your problem, if that's the case. Trust me. That's what I did on my first N3DS and spent days trying to figure it out until I ended up pulling a pad off of the MB while attempting to de-solder a wire. Permanent brick. Silver pen can't fix it. Blob of solder can't fix it...

anyway, use the recommended ground point on the bottom left of the board.

Edit: on second thought, maybe you didn't do that. But why is everything in 1 piece? I can't tell how long the wires are, but too long and it won't work right either, and can also keep you on the blue screen even when not connected to a reader. There is also a much better CLK point on the other side as well. Try using that, if you're using the correct ground point.

Thanks for this. I too am having trouble figuring this out. Even with a working transcend adapter with a blue screen and popping an "insert G drive" window I still can't get it to work. I grounded to sd shielding though. Isn't the sd/game cart shieldings are perfect for GND?

Does anyone know the name of the white connecters people are using. I need to get some from maplin in UK to do my hard mod
