I recently messed with my wii via following a guide and overlooked the step to make a backup of my NAND before actually messin with the wii. I then went and made a backup of the NAND afterwards; After I downgraded the IOS. I am askin if there is a way to restore my NAND to a clean state so that I can make a backup of it. Nothing has happened to my wii other than maybe an orange power off glow rather than a red one. Just that I want to be safe and have a clean NAND so that if my wii does brick, I can use the clean nand rather than the modded one. Anyone can help?
