My wii has been semi bricked for quite some time. I have an original wiikey installed. What is the easiest method to unbrick it? If i play new super mario bros pal version i shouldn't update right? i put the new super mario bros wii game in and i get an error. it says

What do i do to fix this?

an error has occurred. press the eject button and remove the disc, then turn the wii fonsole off and refer to the manual for troubleshooting

My other backups work fine just no way to get into the settings it's an ntsc wii with the original wiikey
