Team Twiizers has found a way to install HBC, DVDx, and Boot Mii on 4.2. Team Twiizers has found an IOS exploit to allow installing the HBC and Boot Mii on 4.3.DVDX isn't installed as its code (the AHBPROT channel loading flag) is moved inside the Home Brew Channel's launcher.Updating is recommended to gain access to USB 2.0 functionality.The Hack Mii Installer v0.8 includes all these changes.NOTE: DON'T FOLLOW GUIDES INVOLVING IOS DOWNGRADES.Hack Mii Installer will now work on all Wiis, but on some newer Wiis, downgrading an IOS will cause the IOS to become useless.Word to the wise: It looks like if you update your Wii, the Twilight Princess save data will be deleted if it corrupted by the well-known exploit.A new update to the Wii system will “check for and automatically remove such save files” that are unauthorized save files.
Update: “With this update, you can now move a Mii from the Mii plaza to the Mii parade in the Mii Channel.
Which installed new versions of all IOS to block the Trucha Bug.
Most Wii homebrew can still be loaded via HBC, but any apps that rely on Fake Signing will not work.
Bannerbomb does not suffer from this inconvenience, as it is never copied to the console. You will need to use Bannerbomb to run the Hack Mii Installer, and from there you can install the HBC, DVDx, and Boot Mii. The Banner Bomb v1 exploit currently cannot be used but Bannerbomb v2 can be used.
You could also use Indiana Pwns Return of the Jodi or Smash Stack to load homebrew. Banner Bomb v2 can't be used, but Indiana Pwns Return of the Jodi and Smash Stack still work.
