I had a 4.0U wii with cIOSrev9 and Preloader .29 and loading games via USBloader GX. Went into homebrew and was prompted with an update screen so I updated and also installed BootMii as an IOS as it could not be done as Boot 2 (Error -2). Then I updated to cIOSrev13b...and now the problem starts . When I power up the wii the health warning screen will show and then I can hear the music for the system channel screen but the screen is black. I am able to load the system menu from preloader and see and use the channels no worries. If I load the homebrew channel via preloader, I can also back into the system menu that way. But for some reason I can no longer just turn on my wii normally and have it work. Any help would be much appreciated. Thank you.
