Thread: Ultimate Upgrade/Downgrade Guide

This post is now out of date - use one of the stickies instead



It looks like lots of people need some help with this. This works for all regions (Downgrader may have some issues with Korean Wiis).

MANY PEOPLE ARE MESSING UP BY NOT FOLLOWING EVERY STEP!
FOLLOW ALL OF THEM EXACTLY AS THEY ARE!

Note that the best firmware for Homebrew is 3.2

First of all, you will need to install the Homebrew Channel (HBC)
I made a guide to installing it HERE

Downgrade from 3.3 ore 3.4

Downgrading from 4.0
After getting to 3.2

DOWNGRADING WITH 3.3v3 OR 3.4
If you have 3.3v1, you can skip to step 10.
Original post by n2locarz. I added some new links.

After the HBC is installed on your Wii, delete everything on the card.
TAKE OUT ANY GAMECUBE CONTROLLERS AND MEMORY CARDS

Step 1 - Download these files:

Step 2 - Extract the Wii_Fix_Tools_Full_zip and drag the "apps" and "wad" folder on the SD card.

Step 3 - Using the ‘Homebrew Channel’, open ‘WAD Manager 1.3’

Step 4 - Press ‘A’ on the Wii Mote 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 5 - Using the ‘Homebrew Channel’, open ‘Custom WM’. Now using the same method as in ‘Step 4’, install the ‘cios_fix.wad’. Once it has installed the WAD, press the ‘Home’ button to restart you Wii.

Note: If that fails to install, just use 'Wad Manager 1.3'

Step 6 - Using the ‘Homebrew Channel’, open ‘IOS Downgrader’. Just follow the instructions and wait until it finishes installing the necessary IOSs.

NOTE: You're Wii does require connection to the Internet otherwise it won't work. Same for the next step.
If you do have a Internet connection and you get errors while it's installing the IOSs, just restart the Wii and try again.

Step 7 - 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). If it doesn't work the first time (116 error), keep trying. It may take a couple tries.

Step 8 - Using the ‘Homebrew Channel’, open ‘WAD Manager 3’.

Step 9 - Now you should be able to install WADs. Try installing the ‘WAD MANAGER V3.wad’

Step 10 - Downgrade to 3.2 or whatever firmware you want. Make sure you choose the right region or you will semi-brick your Wii. (U = USA, E = Europe, J = Japan)
Use this file with the HBC to downgrade. Make sure you put it in a folder in the 'apps' folder.

You can also use AnyRegion Changer to downgrade.
WARNING: When using AnyRegion Changer, skip straight to the "Downgrade to 3.2" option. Do not changer any other region or shop settings.

Your Wii is now downgraded!

UPGRADING FIRMWARE

Assuming you have the HBC, all you need to do us use this file and choose your firmware.

If you don't have the HBC, use the Twilight Hack and put the file from the above download on the root of your SD card.

AFTER GETTING TO 3.2
The most recommended firmware is 3.2. If you used the downgrade or upgrade option to get to 3.2, I recommend installing Starfall. Srarfall is an app that installs system menu hacks that you choose. You can install these hacks:

• Region free GC games with video mode patch
• Region free Wii games
• Region free channels
• No mainmenu BGM
• Start rescue-menu when Y is held on 1st GC controller
• Remove rescue-menu diagnostic disc check
• Replace health warning with backmenu
• Skip disc update check

I recommend:

• Region free Wii games
• Region free channels
• Start rescue-menu when Y is held on 1st GC controller (incase you brick your Wii)
• Skip disc update check

Make sure you know what you are doing. Don't ask questions about it in this thread. This is optional.

I will update this thread as new updates come out.

Try going to the Wii system settings. If you get some kind of http error, you have a semi brick.
