Can I downgrade from 4.0 ?

Hi all out there. I am BRAND new to this so please bear with my very limited knowledge. My version was 3.4 - I went on hols and left my nephew a key - big mistake. He wanted to go shopping and the Wii told him to update...... so he did. Now I am on v4.0, HBC no longer works at all. I used Zelda beta 2 to get HBC and was fine with it - until now. Can anyone help me to get back to a previous version from the fatal 4.0.

I'm afraid you can't unless you had a cIOS installed before the update.

You're just gonna have to sit patiently until a new exploit is released.

Thanks for the answer - got it sorted though - swapped with a mate who doesn't want to use HBC, used his 3.4E and the great tuts on this site to downgrade to 3.2E - hey presto. All I need now is a region free wad manager to get all my HBC stuff runnng - sweet !
