I recently brought wii u and it came with firmware 3.0. I installed homebrew channel on it. Now I want to update to 4.0 through MK 8. I guess my question is, 1. If I do, will the update wipe the homebrew channel 2. If it do wipe the HBC, will it prevent me from installing it again. Sorry if it's a newbie question. I'm new to wii u and never have wii either.
