BootMii for your Wii

With BootMii, if you install it in “boot2″, you can pretty much do anything (software wise) you want to your Wii.  Once you make a good backup of your NAND memory, if you brick your Wii, or otherwise hose it, you can simply restore to the backup you made with BootMii.  Now that I know about it, I wouldn’t recommend updating any Wii without it!

Ideally, you want to install BootMii and take a good backup of your system before you do any hacking that results in anything being on your Wii permanently (like patching your IOS).  Your NAND memory (basically, where the OS lives) can be completely backed up and later restored.

Note:  I believe BootMii Beta 3 has an issue restoring that requires you to make a change to be able to successfully restore a backup.
