Guarding against bricking your Wii with BootMii
BootMii allows you to make a backup of your Wii's NAND so that you can recover from almost any type of brick1. It does this by installing as boot2 on a compatible Wii, and is executed before the Wii system menu . BootMii also allows the execution of special homebrew applications not usable by
What you should install first
What you need
- SD Card (an SDHC card is also suitable if you are at firmware version 4.0 or higher)
- Spare 528MB of space on an SD/SDHC card if you want to perform a Wii backup
Installation if you don't yet have the HBC.
- Launch the Hackmii Installer using one of the methods on this page
- Read the warning message and wait for the "Press 1 to continue" prompt to appear
- When the prompt does appear, push 1
- Take note of what you can and can't install then push A to Continue.
- Select "BootMii…" with the D-pad and push A.
- BootMii can be installed in two modes, boot2 or IOS
- If you have a newer Wii (from the 2nd half of 2008 onwards) then you can only choose IOS install.
- Boot2 is much safer than IOS install, so you should choose that if you can.
- Select the option best suited to you (boot2 or IOS) with the A button.
- The installer will warn you that files need to be installed to an SD card. Insert one if you don't want to use your current one.
- The installer will ask you if you want to install BootMii, select Yes, continue.
- BootMii should install. If you installed as boot2, reboot the Wii and it should start. If you installed as IOS, use the Homebrew Channel to start it (there will be a new button)
Upgrading or installing BootMii if the HBC is still installed
- Create a subdirectory called sd:/apps/BootMiiHBCUpgrade/ on your SD card.
- Download Hackmii Installer v0.8 or later from this page.
- Unzip HackMii Installer and copy boot.elf to sd:/apps/BootMiiHBCUpgrade/
- Start HBC and load the /apps/BootMiiHBCUpgrade/boot.elf application.
- Follow installation steps from step 8 of the appropriate installation method.
- If BootMii is installed as boot2
- Restart your Wii. The BootMii menu should load.
- If BootMii is installed as an IOS
- Start the Homebrew Channel and push the Home button.
- Choose the BootMii option that should now appear.
- BootMii only supports Gamecube controllers and the Wii's own buttons (Power/Reset/Eject)
- Wavebirds are sometimes recognised/sometimes not. Try ensuring they are switched on before turning on the Wii
- The Power button chooses the next option and Reset button selects an option. Eject is only neeeded when prompted.
- If BootMii is installed as boot2, you can make BootMii autoboot to the system menu or Homebrew Channel after a specified number of seconds of inactivity by altering sd:/bootmii/bootmii.ini by adding or changing the following lines (in particular, note the lack of the # character):
- AUTOBOOT=HBC (or SYSMENU)
- BOOTDELAY=5 (or any other number)
Making a backup
- Navigate to the Options Menu (fourth one, a pair of cogs) using the Power button or Gamecube controller and push the Reset button or A.
- Select the first option
- Insert an SD card with 528MB free and continue, pushing the requested buttons
- There will usually be several bad blocks during install. This is normal.
- I can't control BootMii with the Wii Remote. What's wrong?
- See the start of the Using BootMii section above.
- How do I stop BootMii as boot2 running every time I boot my Wii?
- Use the autoboot option mentioned in Using BootMii above or rename the bootmii directory on your SD card.
- How much space does a NAND backup take?
- About 528MB.
- To do any other homebrew with your Wii, you will need the Homebrew Channel
