Wii U Camera Won't work

Cause: There is something faulty in the software.

Solution: We all love the relaxing Wii U splash screen, so please leave the chat and restart your GamePad.

Cause: There is a mod in the console

Solution: Please pause any homebrew-related mods and re-mod the console when you are done.

Cause: Storage is full (e.g, too many games downloaded)

Solution: Please go to the Mii Maker and delete 5 to 20 Miis and delete 1-2 unused games (more is better)

Cause: Faulty Camera

Solution: Use the official iFixit guide to replace your camera
