while i was installing some cios (i believe it was 249 or something like that), it gave me an error message... something like 'can't find xxxxxxx, ret = -1, then immediately said "successfully installed cios"... which is a false message i believe. so anyway, how do i uninstall it? i believe this installed a bad cios on my wii and i need to get rid of it.... or can i just install the same cios again? will it just overwrite it so i don't have to uninstall it? i'm confused.. help plz.
