BootMii allows anything from Recovery modes (creating a practically unbrickable Wii), to lazy access of the [[Homebrew Channel]]. For example, if you have corrupted the [[System Menu]], you can use [[DOP-Mii]] to reinstall the [[System Menu]]. Unfortunately, all homebrew currently require an [[IOS]], because [[libogc]] requires one. However, there is [[Mini]] (a homebrew IOS-like software), which can be modified specifically for the program, ie, for better communication to the Linux kernel.

BootMii is a modified version of [[boot2]], which is loaded by [[boot1]], which is loaded by [[boot0]]. '''boot0''' is part of [[Hollywood]] and read-only. '''boot1''', although stored on the [[NAND]], is signed by a value in write-once memory and therefore cannot be changed without rendering a console unable to boot. '''boot2''', however, can be modified (with some restrictions). This means it can be hacked, updated, and corrupted. BootMii hijacks the [[boot process]] before the normal '''boot2''' is run, optionally allowing code to be run directly from the SD Card. This has many advantages, such as making it very difficult to [[brick]], and slowing Nintendo from blocking homebrew. Unfortunately, the only way we could completely stop Nintendo from blocking homebrew is by patching updates on-the-fly, or somehow preventing overwriting '''boot2'''. Along with the [[System Menu 4.2]] update, Nintendo released a new version of '''boot2''' (boot2v4); there is nothing in boot2v4 that prevents BootMii from working, but it will overwrite an existing BootMii installation when it is installed.

Consoles made after some point in 2008 (no concrete date is known) have a new version of [[boot1]] that patches the vulnerability which allows the console to boot a modified [[boot2]]. The Hackmii Installer will detect this situation and refuse to modify '''boot2'''(see more at [http://hackmii.com/2009/02/bootmii-and-the-new-boot1/ Hackmii]). Since '''boot1''' cannot be updated, all consoles already manufactured before this update are safe. About 10% of the consoles that ran the BootMii Checker tool have the new '''boot1'''.
