I followed the stickied guide above to fix my system after an accidental update from 3.2U to 4.2U. All my loaders and apps are running perfectly (Thank You!). I keep reading threads about bricked wiis needing Bootmii installed as boot2. I have bootmii installed but I don't believe it is installed as boot2. How can I verify if that is the case? If it isn't installed as boot2, can I go back and do that? Am I protected from bricks? Thanks.
