how can i upgrade my wii

hi there im running my wii with homebrew using the twilight hack on 3.2e
was wondering can i change this system so i can run on 4.1 update as the twilight hack wont allow you to do this or is there a way to remove the twilight hack to start a fresh with bannerbomb ?????? forgive me asking so many questions but kinda new to modding wiis an just needed a lil help

Using dop-IOS MOD, install every IOS above 30, the channels and 4.1

Or, better yet, just update to 4.2 There's honestly no permanent damage done by it.

fresh upgrade thru nintendo to 4.2 (just don't do it during a huge lightning storm and you'll be fine (actually odds are you would be fine then too))

So much easier than any other method.
