hello evreyone, how are you doing? I just updated my wii from 4.1U to 4.2U, and when I was updating it, I had some trouble installing some of the wads that were recommended to have while updating, but I had a Nand backup, so I continued with my updating. The updating went smoothly, untill I inserted my New Super Mario Bros disk and the screen became black ( Which I tried before the updating and worked perfectly ). when I tried some other games, they asked my for an update ( even some old ones, like mad world ), but a few games worked. When I tried to restore my old Nand backup files, a message told me that the files are for a different wii !!! Nothing happend to my homebrew channel, so if there was any way to fix my wii please tell me ( even downgrading is fine ). Thank you, and sorry for the trouble ( and my bad english ).
