start up wad manager 1.3 iso16.
run ciosfix.wad
than install gamma /ciosrev7
My Wii has HBC on it, and is on 3.4
So, looking at this, I found this little step-by-step thing.
QUOTEStep 1 Lets assume you have already updated your Wii to the latest Firmware.
Step 2 Install the ‘Homebrew Channel’ onto your Wii if you dont have it already (see below)
Step 3 Put the contents of this zip onto your SD Card.
Step 4 Using the ‘Homebrew Channel’, open ‘WAD Manager 3’.
Step 5 Press ‘A’ on the WiiMote once. The Wii should detect a SD Card. Press ‘A’ again to see a list of WADs on the SD Card. Use the ‘D-Pad’ to select ‘IOS16-64-v257-prod.wad’.
Press the ’+’ to install the WAD. Once it has installed the WAD, press the ‘Home’ button to restart you Wii.
Step 6 Using the ‘Homebrew Channel’, open ‘Custom WM’. Now using the same method as in ‘Step 5’, install the ‘cios_fix.wad’. Once it has installed the WAD, press the ‘Home’ button to restart you Wii.
Step 7 Using the ‘Homebrew Channel’, open ‘IOS Downgrader’. Just follow the instructions and wait until it finishes installing the necessary IOSs.
Step 8 Using the ‘Homebrew Channel’, open ‘Install Shop IOS51’. Say ‘Yes’ to installing the ‘IOS51’ and ‘Yes’ to patching a fix but ‘No’ to the ‘Wii Shop Channel’
(it shouldn’t matter if you install but it won’t make any difference).
Step 9 Using the ‘Homebrew Channel’, open ‘WAD Manager 3’.
Step 10 Now you should be able to install WADs. Try installing the ‘WAD MANAGER V3.wad’ (use this channel to install any WADs in the furture) and ‘Wii Gator.wad’.
Other apps should also work as well such as ‘AnyRegion Changer’.
