In this video I will show you how to backup your Nintendo Switch NAND. If you love console modding, then backing up the NAND is an important task to do. So if anything happens, you can restore the console to its previous state.
For this guide, you need to have an RCM jig and a USB Type C cable. You need a MicroSDXC card too, better use a 64GB exFAT formatted card.
If you use a FAT32 formatted card or use a 32GB or less card, then you will get a partial NAND dump. You can always join it later by using a joiner script.
