Section V - Patching IOS80

This step will brick your vWii installation if it fails for any reason (power outage, etc) which will require a vWii NAND backup to restore. Ensure you have yours before proceeding with this section.

  1. From the Homebrew Channel on vWii, launch Patched IOS80 Installer for vWii
  2. Read the warning, then wait 30 seconds for it to allow you to continue
  3. Press (A) to install
    • This should be very quick
  4. When it has completed, press any button to return to the Homebrew Channel
  5. Exit to the vWii Menu

You can now install and use any Wii homebrew such as USB Loader GX, Wiiflow, CFG USB Loader, emulators, etc.

External hard drives must be connected to the upper back USB port of the Wii U to be detected by vWii. This cannot be the same external hard drive you use for Wii U games. If you are using an external HDD that does not have its own power source, then you will need a Y-cable.

Ensure any .wad files (channels, forwarders, games, etc) you install are formatted to work properly with vWii first. If you install a .wad formatted for a regular Wii console, you will brick the vWii which will require a vWii NAND backup to restore.

Installing custom themes on vWii will brick your vWii.

Removing .wad files manually without knowing what you are doing will brick your vWii.

Installing Priiloader will brick your vWii.
