Damnit! I had a 4.1U Wii, with a Wiikey, preloader, cIOS and everything... I wanted to upgrade to 4.2, so I followed the Simplistic Mod guide. I downloaded newmod.rar, officially updated to 4.2, and went into SD card menu. But then, it completely froze. I waited for 10 mins, but seeing that nothing happened, i unplugged the Wii and restarted it, but now my system is corrupted! What can I do?
