FlashHax is an exploit for the Wii that is triggered by using the Internet Channel. Unlike other exploits, this doesn’t require an SD card.

What you need

  • A Wii with an Internet connection on system version 4.3
  • The Internet Channel


  1. Open up the Internet Channel on your Wii. If you don’t have it, then try str2hax or LetterBomb.
  2. Go to flashhax.com in the browser and bookmark the page.
  3. Open the site from the bookmark. It’ll then proceed to download and load the HackMii Installer. It may take some time as it is downloading the installer over the internet.

If the HackMii Installer doesn’t load and it instead freezes (you can’t move your cursor), please restart your Wii and repeat step 3 until it works. It might take multiple tries, be persistent!
