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.
nice explanation! thank you.
so as the people using a cios_fix and updated have there console run on that particularly IOS.
But if the cios that comes with the new loader would be called IOS250 installation should work.
Maybe a bit off topic, but what can/would happen if I use the AnyTitleDeleter and delete all the ios that are patched from the update.
Leaving only IOS249 at it's place. Could it be possible then to copy the old unpatched IOSes or FS Dumper output at the place again?
Supercool330Well I may be able to help the issue (not much but some). I have made a slightly modified version of patchmii that tries to install patchmii (IOS 254) using cIOS (IOS 249). This would allow a user to install a new version of of cIOS, but you would have to have either patchmii or cIOS installed for this to work. Give me a few minutes to make sure it works the way I think it should.
