Hey there, I bought my Wii U off of Craigslist a few months ago and it won't read any Wii games so I can't homebrew it (Brawl & Lego Batman). I just called Nintendo and they said that my warranty has expired and the repair would cost me $99. Is there anything I should try or do to try to fix it? I'm tech savvy so if there are any repair tear-downs I'd be more than willing to do them. Thanks! In case it's needed, its on 5.5.
