What do you mean? I don't get it. Can't you just uninstall the current cIOS with the wad manager? If so what order would it be uninstalled? Just uninstall the cIOS fix? cIOS fix and the original? If both what order what order?
Let me see if I can explain the technical side of things. The new Nintendo update, patches ALL IOS's, to remove a certain bug (fake signing bug). Without this bug, homebrew programs are not capable of installing anything new to the Wii system anymore. So that means, you can't install WAD's, you can't install the Homebrew Channel, you can't install a new cIOS.
However, if you have a cIOS already installed, Nintendo didn't patch that one. And since a cIOS is always based on a IOS and has it's basic capabilities, you have an IOS on your Wii that still has that fake signing bug. This is because the current cIOS releases are based on IOS's that still had that bug, so the cIOS you have installed also still has that bug.
Now, that means that homebrew software can use that cIOS, to install new stuff to the Wii system, like a WAD or a new cIOS. But if you uninstall the old cIOS first, you don't have a IOS on your Wii anymore that has the fake signing bug, so homebrew software can't install new stuff to your Wii anymore, including a new cIOS.
