Brick/System Menu brick

A system menu brick with an Opera error, note that it looks similar to a semi-brick.

Generally speaking, a "full brick" occurs when the System Menu refuses to boot for any reason. There are two typical symptoms of a full brick:

1. The Wii displays an Opera error message instead of the “WARNING SCREEN" when the Wii boots and does not check the disc drive for a disc before displaying the error.
2. The Wii gives NO SIGNAL.

Similar bricks occur when there is a broken Bluetooth Module, or non-Korean System Menu on a Korean Wii. The former can only be fixed by replacing the module.

Fixing this brick

If you still have Priiloader, use it to enter the Homebrew Channel and re-install the original theme file/original Wii Menu.

In case you do not have Priiloader or your Wii is not modded, you can try BlueBomb.

Alternatively, Recovery Mode can be used to attempt a fix.

Cause of this brick

A full brick is caused when /shared2/sys/SYSCONF is missing, damaged, or has the "reconfiguration" flag set, and the /title/00000001/00000002/data/setting.txt has the wrong region in it. When the system boots, it attempts to load the initial setup menu due to the damaged SYSCONF, but for the same reasons as the semi-brick, it fails to find the page for setup and instead shows the Opera error.
