I had homebrew installed on my wii and this morning my son accidently did a system install. Now the Wii has a black screen. I troubleshooted with Nintendo, nothing I can do but send it in. Question is, during the repair, will they find homebrew channel and if they do, does that void my warranty?
We don't like talking about modding on WiiChat, sorry.
But to answer your question: yes, most likely.
