If this was caused by a theme you installed, use MyMenuifyMod to re-download the original theme file.
If this was caused by a System menu WAD you installed, use [NUS Downloader](https://wiibrew.org/wiki/NUSD) to re-obtain your original system menu.
Be cautious when downloading the System menu WAD. Make sure to pick the same version with the corrected region.

If you are actually in the process of a region change, use [ARC-ME](https://github.com/modmii/Any-Region-Changer-ModMii-Edition/releases) to automatically fix all your region settings to match your System menu.
This brick is a more fatal version of a [Semibrick](#semibrick). If your SYSCONF gets corrupt or damaged, the Wii will regenerate it and start the setup phase.
However, the setup pages are in a similar location to the Wii settings pages. If you have an incorrect region System menu or theme, the Wii cannot find them. ![System menu brick](/images/bricks/sysmenu-brick.png)
To fix a mail brick, enter Maintenance mode by holding `+` and `-` on the Health and Safety screen. (不要按 `A`!) <br> Enter the Homebrew Channel, and use [cdbackup](https://oscwii.org/library/app/cdbackup) to delete your message board data.
This brick arises when your Wii's Wi-Fi (or Bluetooth) module is damaged or not inserted properly. In such cases, the Wii gets stuck on a black screen while awaiting a response from IOS.
You can try and differentiate by checking if your Wii remote still powers on your Wii.
This will also happen on the Wii mini if you install a normal Wii IOS, because the Wii Mini does not have a Wi-Fi module.
Since this brick most often occurs after the System menu updates, Priiloader will not be present.
Korean Wiis also released with System menu 3.3, around the time that Nintendo [fixed the Trucha bug in boot1](https://wiibrew.org/wiki/3.3#Changes), so BootMii as Boot2 cannot be installed to any Korean Wii.
The only way to fix this brick is a way to launch homebrew by launching a game through the Recovery menu.
This brick happens when the System menu's IOS is a [stub](http://wiibrew.org/wiki/Stub_IOS). This is usually the consequence of attempting to downgrade your Wii menu.
