Hi, I want to upgrade my Wii to 4.0u. I have the Hombrew channel and all the Homebrew apps working great including the USB loader. Currently I have: - 3.4u firmware -IOS16 installed -cIOS rev 10 installed -Waninkoko's 1.5 USB Loader What do I need to update though Nintendo safely? I read something about a patched IOS60 before updating to 4.0, but I'm not clear on it. Also, would I still be able to install WAD's if I update to 4.0? My biggest concern is the USB Loader and whether or not updating will affect it.
