There are 2 versions of bootmii, bootmii as an ios, and bootmii as boot2. If your bootmii is installed as boot2, than you will be able to run it just by turning the wii on with the bootmii sd card in it, however if you only have bootmii as an IOS, than to start it you have to load it with the homebrew channel or priiloader, or some other program.

So basically: boot2 = starts when you turn on your wii IOS = needs to be started with some other app So, if you want to restore the backup, you will need to have bootmii as boot2 to do it Edit: although it may be easier to downgrade using something like dopmii or anyregion changer, that way you won't lose any channels or game saves or other data in the process. As Mantis has said, there is no real reason to downgrade from 4.3 to 4.2. If updated to 4.3 officially, he will have a stubbed IOS 70. If you can re-install 4.2 IOS 70, you do not have any reason to downgrade. If you can re-install IOS 70, this implies you have a way to load homebrew. The only downside to 4.3 is you don't have that many methods disposable to install the homebrew channel. Not to mention, I forsee a brick when downgrading (IOS 70 is stubbed, install 4. Bitlord 1.1 For Windows 7. 2 system menu = brick) A good idea would be to install priiloader.

Rabindra Sangeet Debabrata Biswas. If you have bricked your Wii or have a severe issue that is causing things not to work correctly, you may benefit from using the NAND formatter. Jan 21, 2011 This Site Might Help You. RE: Where can I download a NAND backup for a WHITE Wii 4.3u? Now there is a reason for it needing to be white wii because I.

There is a.5 priiloader for 4.3 menu which has a risk of bricking your wii. There is a bug that causes priiloader to crash when installing and if you don't have bootmii as boot2, then you are screwed. The bug occurs if you do not have an active internet connection running. Then download latest priiloader hacks and re-enable bannerbomb a bug in 4.1, 4.2 system menus that allows you to run.dol files without the homebrew channel.
