BootMii Backup ​

BootMii allows for backing up and restoring your Wii's NAND storage. This page will guide you in backing up your Wii's NAND to an SD Card, which you can then use however you like.

Please read the below information before proceeding further.

Important Information

  • After the completion of this guide, two files will have been created on the root of your SD Card: nand.bin and keys.bin. nand.bin is a backup of your console's internal memory, while keys.bin are your console's keys.

  • If you have BootMii installed as boot2, you will need to launch BootMii by restarting the console. Skip steps 1 and 2 if this is the case.

  • You must use the buttons on your console or a GameCube controller plugged into port 1 to navigate BootMii. To navigate with a GameCube controller, click left/right on the +Control Pad to move, and press A to select. To navigate with your console buttons, press POWER to move right, and press RESET to select.

  • Please note that restoring a NAND backup is usually a last resort. With that said, you can use the BootMii Recovery guide to restore your NAND backup, where more information is provided about the risks and alternatives.

  • Family Edition Wiis and Wii minis CANNOT restore NAND backups. This is because of the lack of GameCube ports which are required on non-boot2 Wiis to enter the restoration confirmation code.

DANGER

Important Warnings

  • You need an SD card to use BootMii at all, but especially to create a NAND backup. If you do not have an SD card on hand right now, you can skip this page, but it is HIGHLY RECOMMENDED to return to this page later to back up your NAND.

  • If the Launch BootMii button does not appear in the Homebrew Channel, re-launch the HackMii Installer and install BootMii.

  • If the screen stays black and the blue disc drive light is blinking upon launching BootMii, you are missing the BootMii files on your SD card. Download this zip file and extract it to the root of your SD card, then try again.

Requirements ​

  • An SD card with a minimum 512MB of free space (1GB or more recommended)

Instructions ​

  1. Power on your console.

  2. Launch the Homebrew Channel.

  3. Press the HOME Button, then select "Launch BootMii".

  4. You should see an image similar to the below now on your screen:

  5. Select the Options button (the icon with the gears).

  6. Select the first button to the left.

  7. A NAND backup will start. You can watch the progress on the screen.

    • "Bad Blocks" are normal, and mostly originate from the factory due to NAND binning. Don't worry when you see some on a NAND backup.

  8. After the previous step completes, BootMii will verify the backup. Ideally, all the blocks should be green after the verification process.

    • If you have factory bad blocks with uncorrectable pages, these blocks may fail to verify. As long as all non-bad blocks are successfully verified, this should be fine.

  9. Press the Back button (the one with an arrow), then press either the Wii Menu button or the Homebrew Channel button to exit BootMii.

Autobooting ​

If you were able to install BootMii as boot2, but don't want to load the BootMii screen every time you turn on the Wii, you have the option of setting it to autoboot to the system menu. This should make it so you don't even notice you have BootMii installed as boot2.

  1. Open SD:/bootmii/bootmii.ini with a text editor, such as notepad.
  2. Change #AUTOBOOT=SYSMENU to AUTOBOOT=SYSMENU by deleting the #.
  3. Then change #BOOTDELAY=5 to BOOTDELAY=1 by deleting the # and turning the 5 into a 1.
  4. Save the file and exit.

INFO

You can also use the BootMii Config Editor app on the Wii to change these settings.

Uploading NAND Backup to Dolphin Emulator ​

Your NAND backup can be utilized in Dolphin Emulator. This is completely optional.

  1. Get the latest beta or development release of Dolphin Emulator from the Dolphin Website and install it to your device.
  2. Open Dolphin Emulator.
  3. Click on the Tools tab, scroll down to Manage NAND, then select Import BootMii NAND backup....
  4. Locate the nand.bin found on the root of your SD card and select Open.
  5. If it asks for a keys.bin, locate it on the root of your SD and select Open.

TIP

Continue to Priiloader Installation

Priiloader adds a secondary level of brick protection, and is highly recommended even if BootMii was installed as boot2. It is especially important for users of BootMii on IOS.
