Hardware I'm selling my 3DS, how do I erase my data?

[Devrim]

Hi,

I'm selling my 3DS and I was wondering how I should erase my data. I have Emunand and CFW on it and my NNID linked to the 3DS.
The SD card has multiple partitions if I'm correct, how do I reset that?

Go into SysNAND --> Do a "Format System Memory" on it. Afterward,Put the SD Card in a computer and use a partition tool like Gparted (linux) or something like EaseUS Partition Manager (Windows) to format the whole SD Card as "FAT32". now reinsert the SD Card into the 3DS and that should be it.
