My wii was semi-bricked and sw upgrade to 3.4J. Afterwards, it was accidently upgrade again with US or EU disk, Dead Space extraction. As the upgrade process took only few seconds, so i think it should be still 3.4 but semi-bricked again. Furthermore, there is no SD icon on the left lower corner that 4.0 should be. So, i believe it is still 3.4 but semi-bricked. Play games are no problem except Mario Kart and Super Mario Galaxy. It always show error and see manual (something like that as i cannot read Japanese).
Could anyone give a hint to solve the problem?
BTW, it is HW hacked only, no any other sw installed.
Looks like you need a disc with an update from your region. Have a look at this thread: http://www.wiihacks.com/recommended-...-do-about.html
