Hello, I have a first gen Wii (bought it when it just came out), and I've had it with 3.2U for some time now, with Homebrew Channel, WiiFlow, and a bunch of other stuff installed. I've read that 4.0 and beyond supports SDHC cards, which would of course be of great use. My question: is the Bannerbomb method a reliable way to "open" the Wii with 4.0 installed? And will I have to reinstall everything if it does work? Thanks for your time!
