Hi. A friend upgraded his hardmodded Wii. He doesnt know in wich version it was, but now it shows a 001 error everytime we try to run a game. I cant open the Wii (I dont have the proper tools), so I dont know which was the chip. What should I do? Should I try downgrading? Maybe I could downgrade several times until it works but dont know how to do that. DOP/IOS should do the trick, but I still not understand that much, so I may en bricking it. Any help appreciated.
