I have a D2PRO9 installed that should bypass updates. However, when I go to run LEGO Rock Band from the disc channel, it tells me that I need to perform a Wii System Update. When I go ahead and do so (since I have BootMii as Boot2 anyway, and am already on 4.2), it messes up the Homebrew Channel. The HBC is now upside down. In order to reinstall it, I had to run the IOS Downgrader, but then Lego Rock band requires an update again. Is there a particular IOS I need to update? Or another way to run this from the disc channel?
