So I picked up a wii for 16 bucks. Got home loaded it up it says system files are corrupt and shuts down. I promptly booted it in maintenance mode, wiped, same error. I updated to 4.3, did soft mod with modmii where it would install all active ioses thinking it would maybe fix it. Still have the error. I do have a nand backup. Everything works in maintenance mode. Is there a way I can find out what's wrong? Thanks!
