Hacking Updated Wii Shop like an idiot

[ChaosTheorySD]

So a friend asked me to hack his Wii, but I've been putting it off since 4.2 came out. I finally did it tonight and everything was working smoothly until a message popped up asking me to update the Wii Shop Channel. Against my better judgment I did it and now things aren't so smooth anymore. The regular Homebrew Channel still works, but anything requiring a custom IOS (Backup Channel, WAD manager, etc) freezes the Wii. Can I recover from this? Do I just repeat the process again from the beginning (I followed this guide)?

If worse comes to worse, could I always just format the Wii and do everything from scratch?

just reinstall the stuff that don't work!
