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 > Format
You are about to format PATH
This cannot be undone. Are you sure you want to do it?
Click “Yes” Formatting nand…
- 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.txt
Probably should change the “Code” and “SerNo” to what’s on the bottom of your Wii.
- 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.
