It hardly achieved that goal, though, because just two days later a new version of the HackMii installer was released that brings full homebrew capabilities back to all Wii consoles, including unmodified consoles running 4.2. However, as part of their attempt to annoy homebrew users, Nintendo updated the lowest level updateable component of the Wii software stack: boot2 (part of the system bootloader chain). Homebrew users have been using BootMii to patch boot2 in order to gain low level system access and recovery functions (running Linux natively, fixing bricks, etc). The update hasn't hindered this, as users can simply reinstall BootMii after updating (it is compatible with the update). But there's a much bigger problem: Nintendo's boot2 update code is buggy."
