Wilbrand; aka LetterBomb, Mailbox Bomb

Requirements: an SD or SDHC card

• Go to the "Messageboard" on your Wii and navigate to Yesterday.
• Click on the envelope with the pink bomb icon to launch the boot.elf/dol file saved on the root of your SD Card.

Fun Fact! There are two tools that are able to construct this exploit. ModMii uses Wilbrand, which does not require WiFi to construct its "Mailbox Bomb". This is functionally the same as "LetterBomb" that can be constructed and downloaded from please.hackmii.com.
