How To Get The Homebrew Channel

What is needed
A Wii console
An SD card (Check to see if yours is compatible)
Note: SDHC cards can only be used by the Letterbomb exploit. Otherwise you must have an SD card that is 2GB or less.

The HackMii installer
An exploit that matches your wii's version (and the game required to launch it, if necessary)
A computer (Windows, Linux, or MacOS)
An SD card reader for your computer

Preparing the SD Card
(Smash Stack only): If you have any custom stages saved on the Wii (including the default ones), move them to the SD card or delete them. Then rename your private folder to privateold.

If you already have an SD card that is compatible with your Wii, you may be able to put all necessary files alongside the already existing files on your SD card given you have enough room. The Wii directory is called private, and you need to use a folder called private containing Indiana Pwns, Yu-Gi-OWNED!, Bathaxx, Return of the Jodi or Smash Stack to trick your Wii into thinking that it made the file these exploits use.

If you would like, you may rename your current private directory to any name. (I renamed mine privateold) Therefore, when you are finished with the hack, you can delete all hack files and rename privateold back to private to access all of your files again.

If you already have a compatible SD Card that has already been used in your Wii with a renamed private directory, you DO NOT have to format your SD card. Skip to the next step.

If you have a new SD card, or an SD card with no Wii files, it is recommended that you format it using the instructions below.

Important! This process will erase the data on the card and it is therefore recommended that you make a back-up copy of any data you may currently have on your SD card before continuing.

Windows

Open up My Computer.
Right-click on the drive that contains the SD card and select Format....
Under File system make sure you select FAT (see picture to the right).
Click "Start" and let the process finalize.
After the formatting is finished proceed to the next step.
Mac OS
Open up Disk Utility
Find your SD card in the navigation.
Go to the Erase tab.
Change the Volume Format to MS-DOS (FAT).
Click "Erase" and let the process finalize.
After the formatting is finished proceed to the next step.
Linux
Open up a terminal.
Execute the command "mkfs.vfat /dev/<location of your SD card>".
Caution not to reformat your hard disk. Think hard before formatting /dev/sda1, for example.
After the formatting is finished proceed to the next step

Copying files to SD card
Ensure that the SD card slider is not in the Lock position.
Download Indiana Pwns, Yu-Gi-OWNED!, Bathaxx, Return of the Jodi or Smash Stack (make sure you have the correct version for your Wii System Menu) and the HackMii installer.
Extract both the exploit and HackMii installer in an easily accessible folder, such as your Desktop.
Open up the folder called hackmii_installer_X.
Copy file boot.elfB to your SD card.
Finally, from the exploit archive, copy the folder called private to your SD card.
Contents That Should Be On Your SD Card:

private - Extracted From Indiana Pwns, Yu-Gi-OWNED!, Bathaxx, Return of the Jodi or Smash Stack
boot.elf - Extracted From The Hackmii Installer
(optional) privateold - The Wii's existing files renamed temporarily. (see "Preparing the SD Card")
Extract the files to your Desktop
Copy boot.elf to your SD card
Copy folder private to your SD card
Your SD card should look like this in the end

Installing the Homebrew Channel
If you have a new Wii you will only be able to install BootMii as IOS.
When prompted with "Press 1 to continue" note that the new wii remote motion plus with the sync button visible from the back side will not function. You will have to use an older wii remote on which the sync button is not visible until the battery cover is removed.
Select continue.
Go to Homebrew Channel > Install the Homebrew Channel. You will be asked whether you want to install the channel; select yes. After installation you should get a message "finished" and return you to the initial menu.
If possible, install BootMii as boot2; if not install it as an IOS.

Running Bootmii Through HBC
If you're one of the late-comers to the Wii party you may have had to install BootMii via IOS. In that case you have to run BootMii by going into The HBC and hit the "Home" button on your Wii Remote. Place your cursor onto the "Launch BootMii" selection and press A.C



Extra Note
While in BootMii, you should back up your NAND memory. This is mainly for those who have installed bootmii as Boot2, but should still be done when installed as IOS. When in BootMii, you will not have access to the wii-mote, so you will have to use a gamecube controller, or the buttons on the Wii itself. (power button is move cursor, reset button is select option.) THIS ONLY APPLIES TO THE BOOTMII APPLICATION ITSELF, THE HACKMII INSTALLER DOES SUPPORT THE WIIMOTE.
Select the 4th option then hit A/Reset, then you are taken to a new option.
The first corresponds to the backing up of NAND memory, the second; "injecting" NAND back into memory...
Select the first option (you must have at least 512MB of space on SD card to do so) to back up NAND.

Troubleshooting
When I insert my SD card to start the process nothing happens!

One of 4 things has happened:
You didn't place the data on the SD card right.
You went into the save game data menu instead of the channel menu.
You need to set the archive bit of the private\wii\title\aktn\content.bin.
You need the next bannerbomb zip. Download the next one and start over.
OMG!! One of the selections is purple and says I can't install BootMii!!

You haven't read this page in detail, this is explained further up with a picture of the screen.
My Wiimote quit working when i loaded up BootMii! Why? and Can this be fixed?

You didn't read BootMii's FAQ or the README file located in the Hackmii installer archive.
Both state that you have to use a Gamecube controller or the Power/Reset/Eject buttons on the console. In order for this to be fixed a lot of coding will have to be done to make a custom Bluetooth stack and drivers for BootMii. This isn't on the top of the priority list.

I get Error -2 trying to install The Homebrew Channel or DVDx and Error -1 trying to install BootMii

Your SD card slider is in the Lock position, so it is read only.
Will my Wavebird wireless controller work?

Yes, but you must hold any (unused) button when you start up your Wii.
(Wavebird wireless controller now supported in beta3)
Any other questions should be directed to the WiiBrew:FAQ. I'm human after all and can't remember every question that is asked but will update as necessary.
