Hey, I just updated my Wii from 3.1U to 4.2U using the safe updater thing... this thing http://gbatemp.net/index.php?showtopic=184057 I then installed some StatPatch v4.2 stuff. Then I went to my Wii system menu and it says "The system files are corrupted. Please refer to the Wii Operations Manual for help troubleshooting." I searched for a fix, but just found info about fixing it with Preloader, which I don't think I have. I do have bootmii, and when I try to put my old nand backup, it says there was an error opening it. Help please! Posts merged Some more info... I can't load the HBC from BootMii, and when I try to use the Wii menu, it works for about a second, then shows the error Posts merged Wait a minute... I took out the disc, and now it works fine so far... anyone know what the hell was going on?
