ROM Hack 3DS XL - NAND Mod (SD) - PC does not show the 3DS

[ChrisX930]

Hey Guys,

I'm working on a NAND Mod.
Till now, I'm waiting for some MicroUSB Ports I already ordered.
But I want to unbrick the 3DS now (NAND Dump was created with Gateway).
When I connect the 3DS to the PC, the 3DS got the BlueScreen.
But my PC (win8) does not show the device.

Right now, It's look like this:

anyone know where the problem could be?

Have you connected all the wires correctly to the BIG sd card? Check them. And also, is it working?

If it has the Blue screen with only the SD adapter, the it is an issue with the mod itself or a gateway brick. If it is not a gateway brick then check your solder points, look for solder where it does not belong, and be sure to clean your flux if you used some. If it is a gateway brick then you will need a Raspberry Pi to fix it.

It seems there was a problem with my SD Card Reader ^^'
I tried another one, now it works

I replied the same thing in my above post.

Only if it a brick caused by gateway's code. You do not need it for black screen bricks, or downgrading.

Yo, another Problem.
I was able to dump the broken NAND, but I can't restore the backup NAND.

An error occurred when attempting to write data to handle. Error 483

How can I fix this

EDIT:
Okay, the MD5 Hashes of both NAND Backups (the old one from Gateway and the New, bricked one) don't Match.
What can I do to write the old NAND back to the console?

Does your SD card have the little white plastic nib, and it's slid up? If it's slid down or it fell off, you can only read from that SD adapter, but it's write-protected.

OKay, fixed it and got the bricked 3DS XL to work again

That's good
