1. Insert your SD card into your computer.
1. Copy the `private` folder and the `boot.elf` file from the LetterBomb `.zip` to the root of your SD card.
1. Extract the contents of the downloaded ZIP to the root of your SD card.
    + The SD card must be inserted in the SD card slot located in the front of the Wii. Using a USB adapter plugged into the Wii's USB port will not work.
1. Take out your SD card and insert it in your Wii.
1. On your Wii, return to the Wii Menu and then open the Wii Message Board.
1. Load the red letter with a bomb icon.
    + Ensure the date on your Wii is correct, otherwise you might be unable to find the letter.
    + In various scenarios, you may need to look at the previous or next day to find it.
    + If you don't see the red letter, check if any errors appear in the SD card sections in `Data Management`. If any do, there may be an issue with the SD card format or the Wii’s SD card reader.
    + If your Wii freezes after clicking on the letter, you probably chose the wrong region when downloading the exploit. Redo Step 2 and select the correct region.
    + If all is correct and there is freezing, keep on trying until it works.
1. If the exploit was successful, your device will have loaded the HackMii Installer.
