Another thanks from me.
Just finished helping my neighbour who managed to update to 4.3 without knowing what would happen.
Very well written guide. Easy to follow (if you know what you are doing in the first place).
I have two questions though:
1. What does the LoadMii channel do? I didn't find any text explaining this in the guide.
2. If I want to remove a channel (prevent the children from doing stupid things), who do I proceed?
