• Make a NAND backup


    • Creating a NAND backup is similar to creating a system restore point in Windows. Should you ever semi-brick your Wii but can still access Bootmii, restoring a NAND backup is like taking your Wii back in time to before the problem occurred. NAND backups are console specific, so you generally cannot restore a backup from a different Wii.


    1. From inside the Homebrew Channel press the Home button and select "Launch Bootmii".
    2. Press the Power button on the Wii console 3 times to get to the last option to access the Settings (the button with gears), then press the Reset button to select it.
    3. Press Reset to select the first backup option (the button with the green arrow)
    4. Press Reset again to make your NAND backup.
    5. Press any button on the console to exit the NAND backup screen.
    6. Exit Bootmii and launch the HBC by pressing the Power button on the Wii console 3 times to advance to the last option (the one with the back arrow), then press the Reset button to select it. Then press Power 1 time to advance to the Homebrew Channel, then press the Reset button to launch it.

    At this point, or immediately following the completion of this guide, you should remove the SD card from the Wii (it is safe to do so while inside the HBC), backup the Bootmii folder, nand.bin, and keys.bin from your SD to a hard drive, or the cloud, or anywhere safe. You might need these in case of emergencies, so don't lose them. Optionally erase them from the SD card after backing them up, or rename the Bootmii folder to avoid autobooting into Bootmii at startup for consoles with Bootmii installed to boot2. When done, safely remove your SD Card from your computer and reinsert it into your Wii and proceed to the next step.

    Fun Fact! If you ever need to restore a NAND backup, you can do so by launching Bootmii with an SD card containing the appropriately named Bootmii folder, nand.bin, and keys.bin, and follow the procedure described above except this time select the option with the red arrow going the other direction.

    Another Fun Fact! You can extract the contents of your nand.bin using windows tools like ShowMiiWads (see ModMii Classic's Download Page 2), then save it to a hard drive or SD Card to act as an Emulated NAND (or virtual NAND), allowing you switch between the Wii's real NAND and one or more Emulated NANDs. Emulated NANDs can provide much more storage space than the Wii's 500MB. ModMii can help generate brand new Emulated NANDs free of any games saves or other settings if you prefer a fresh start.
