Resetting / revirginizing your Wii to (almost) factory state
- WARNING: This will completely erase everything on your system.
- You’ll need giantpune’s wiiqt tools. It appears they’ve been abandoned for some time so I’ve cloned the code to https://github.com/trapexit/wiiqt just in case. For Windows: ohneschwanzenegger, nandExtract, nandBinCheck, giantpune-tools-dlls. On other platforms they’ll need to be built locally.
- Use BootMii [hackmii_installer_v1.2] to acquire an up to date version of your Wii’s nand.bin. We want to make sure that the bad block list is up to date.
- Using ohneschwanzenegger:
- > Nand Dump > New nand…
- Click “Existing Nand…”
- Leave “Keys”, “Boot 1 & 2”, and “uid.sys” alone. (Set to “From old nand”)
- Click “OK”
- You should see:Set path to nand as <path>
- > Content > FormatYou are about to format <path>This cannot be undone. Are you sure you want to do it?
Click “Yes”Formatting nand…Created /shared2/test/testlog.txtDone!
- Set the “Local Cache” directory to some temporary directory. (“/tmp”, “c:\temp”, etc.)
- In the top text entry line enter “4.3U” or whichever OS version you wish to install.
- Click “Get It!”
- You’ll see lots of “Received a completed download from NUS” and matching “Installed title XXXXXXXXXXXXXX vXXXXX to nand” and finally “NUS object is done working”
- You’ll be presented with the same dialog box as when selecting > Content > Setting.txtProbably should change the “Code” and “SerNo” to what’s on the bottom of your Wii.Click “OK”
- > Content > Write meta entries
- > Content > Flush
- Exit ohneschwanzenegger
- Place the nand.bin file you created with ohneschwanzenegger on the SD card’s root directory. (Overwriting the previously dumped file.)
- Boot the Wii into BootMii using the SD card and restore the nand
- If you expect to restore the nand in the future you may want to setup the Wii and then dump again.
