Hello My Wii (4.2E firmware, YAOSM modchip) was in a state where it had been hacked into oblivion - it did not run backups, it ran most original discs fine (except for The Beatles: Rock Band, which I had to boot through Gecko, else it blackscreened). Today I decided to fix it. First, I realised cIOScorp wasn't doing anything except turning my homebrew channel upside-down, so I tried to update to the latest Hackmii tools to make a NAND backup. I made a backup, then followed some instructions to install Hermes cIOS222 rev3. After I had done this, and nothing seemed to have changed (except my homebrew channel was the right way up again), I thought that having made a backup, there was no danger in updating with Nintendo. I updated with Nintendo, and... it worked! My Wii behaves normally again; most of the time. I can boot originals and homebrew. I haven't tried a good backup disc yet (I tried a very old backup of Super Mario Galaxy, which did give an error when I tried to boot it, but that may have just been a poor quality disc). It is 2:05am and my parents are in bed, so I can't test anything now, but I've decided I would like to start launching backups from my external hard drive. I'm preparing my hard drive for USB Loader GX but I need to know what cIOS I have installed. Will updating through Nintendo have changed anything? Should I reinstall Hermes cIOS? Thanks Kieran EDIT: I should add that I did have to install cIOS 38 or whatever in order to run the Hackmii installer, THEN installed Hermes cIOS. Sorry if this wasn't clear.
