Step 1. Download the latest build of Hekate.
Step 2. Open
hekate_ctcaer_X.X.X_Nyx_X.X.X.zip and extract the
bootloader folder to the root of your SD card (this is what we'll use to back up your NAND.)
Step 3. Boot your switch by injecting the
hekate_X.X.X.bin payload to your switch.
Step 4. Tap on
Step 5. Tap on
Backup eMMC (this is where you'll find different options for what you can back up.)
Step 6. Tap on
eMMC BOOT 0 & BOOT 1 (these are always needed in conjunction with your NAND backup. Always make sure you have them.)
Step 7. Tap on
Close once the backup finishes (may take a minute or two. Close will be greyed out until the backup finishes.)
Step 8. Tap on
eMMC RAW GPP (This will back up your NAND, it's what has your games installed on the switch, save games, and switch firmware.)
Step 9. Tap on
Close once the backup finishes (will take half an hour or so. Once it's done you can tap on Close in the top right. The option will be greyed out until it's done.)
Step 10. Power off your switch, plug the SD into your computer or however you do it.
Step 11. Copy the
backup folder elsewhere on your computer. Delete it after from your SD card (you shouldn't store your backup on your SD card in case the card gets messed up, plus it takes up around 30GB of space which could be used for games instead.)
