Since boot1 cannot be modified, this means that any 'BootMii as boot2' compatible Wiis will always be compatible. We can see that there are various 'booting' steps that happen before the Wii Menu is executed (which is when the health screen appears).īoot0 is on read-only memory and can thus never be modified.īoot1 can be written, but various read-only checks prevent anyone from doing so.īoot2 however, can be modified on older consoles due to a bug in boot1 on those systems. The booting procedure of the Wii goes something like this: The NAND backup function can be found under the 4th button, then the 1st button (the highlighted button in the below screenshot). To make your Wii more brick-proof, make a backup of the NAND before making major changes to the Wii memory. You can navigate through the menu with a GameCube controller or the buttons on the Wii itself ( Power = right, Reset = OK). In the Homebrew Channel, press home to access the menu, and choose 'Launch BootMii'. If you only installed BootMii as IOS, you need to launch BootMii through the Homebrew Channel instead. Every time you boot the Wii with the prepared SD card inserted, you will see the BootMii menu. IT IS HIGHLY RECOMMENDED THAT YOU CREATE A NAND BACKUP AS SOON AS POSSIBLE AFTER INSTALLING BOOTMII. This backup can also be restored later on if needed, providing an additional brick protection. BootMii has the ability to dump this memory to the SD card (as the file NAND.bin). One of the features BootMii provides is the ability to create a NAND backup. This is why BootMii can't be installed as Boot2 on those Wii's. Unfortunately, Nintendo already knew about it before it was even released, so they updated boot1 (which loads boot2) on newer Wii's. As boot2 is normally not updated through a wii system update (which was proven wrong with the 4.2 update!), this is the best brick protection you can get. BootMii is a modification of boot2, which loads the system menu when booting the Wii.

Install bootmii as ios or boot2
