Make a backup.
Always make a full backup of your console, so if something goes wrong you have a know working restore point.
- If you are going to update your SysNAND you can create a backup using Hekate's NYX, It's the easy way.
- For your EmuNAND there are two paths:
- If your EmuNAND is RAW based, you can use a tool like EmuTool (EmuTool GitHub) to backup the RAW partition to a set of files on your PC. That backup can be used later to restore the RAW partition or you can convert your setup to File based EmuNAND using that files.
- If your EmuNAND is file based, making a backup is so easy as copying the
SDMC:/emuMMC folder to your PC.
