    3DS noob here looking to dump my N3DS XL sysNAND before playing around with downgrading and what not. The procedure seems simple enough and I love to solder, so I'm not really worried about the practicality of it, I'm more concerned about the variation in the N3DS XL mainboard. The guides show a N3DS XL with a Samsung eMMC, my US N3DS XL doesn't have the same Samsung eMMC. I've been following the directions from several different sources, but mainly:

    and
    https://gbatemp.net/threads/n3ds-nand-backup-possible-i-hope.381506/ and
    https://3dbrew.org/wiki/Hardware#New_3DS_XL

    My question is, are the pinouts described here (https://3dbrew.org/wiki/Hardware#New_3DS_XL and https://gbatemp.net/threads/n3ds-nand-backup-possible-i-hope.381506/) for the N3DS XL using the Samsung eMMC the same for my system? See below.

    MY N3DS XL (not sure what eMMC this is), IS THIS CORRECT?

    The state with lots of wives
    The pinout is the same. There are 2 types of eMMC for the N3DS XL, Samsung and Toshiba I think. They are different sizes when dumping but are the same process to do so.

    There's also another CLK point on the other side of the board that has a test point the same size as the others.

    Thanks for the confirmations. I am just waiting to receive some headers and a new Dremel bit I ordered. I want to make sure this mod looks good.

    I remember seeing this in a thread. I Will probably end up using it as it will definitely be a bit easier to solder. Thanks for the reminder.

    No worries. Personally, I think you would do better with a small needle file set from Wal-Mart than a dremel. Think damage control. I use a drill with a small bit and needle file to do them like this:
