I've recently bought a new Wii, which I wish to install the Homebrew Channel onto, but due to it being such an old firmware, basically... it won't let me. The only way I can do so is to update the firmware. If I were to update it to the newest version, could I still install the homebrew Channel via the Twilight Hack as normal? If not, how do I update it to an earlier version? Note I don't have any games with an update like that on them.
