Hi. I wanted a Nintendo switch for a long time, but since I already had a 3ds, I couldn't. However, I have now dared to pull it off. I know how to reset the Nintendo myself. But since the SD card is useless without the 3ds, I thought: hey, why don't I also sell the SD cards? Unfortunately I don't know if you can reset them, and if so, how?! I'm grateful for every answer!
Ps: it's 3ds. Not New 3ds (if that's important)
The SD card can't be * reset * properly! But there are a couple of options!
Simply plug the SD into the PC and delete all files. (You can copy them on the PC beforehand)
SD in the cell phone and delete everything
Simply plug the PC into the PC and then right-click> and format (FAT32)> at last just click on Foermatieren. Then the message should come: Delete all files? Just click OK!
