So today, I clicked on the Wii Shop Channel, and it asked me to do a System Update. I haven't been on my Wii for a whiiiiiiiiile, as evident by my 4.0U. I don't know what IOSes I have installed in the past to get games working or whatever. What should I do to be able to access the Wii Shop Channel again without risking losing my homebrew channels and ability to load backups? (I have Homebrew Channel, a Wiikey 1.9s, and bootMii installed). Thanks!
