I finally got my Wii working well with my backups all working last night on 4.1 after days of fighting with it. However, I'm not looking at installing cIOSCORP 3.4 and possibly PreLoader. If I backup my Wii in its current state with BootMii, what exactly gets backed up and what will it save me from? Does it in effect freeze the Wii at this moment in time? If I install 4.2 say and it messes everything up, could BootMii just restore it to a perfectly working 4.1?
