I just went out and bought a new wii and it has 3.4u version firmware on it and i just did the twilight hack and put the homebrew channel on it and I wanted to downgrade to 3.2u but everytime I go to use the wad manager button the screen just goes black and stays black. I have to then hold the power button on the console to reboot it. No matter what wad I try to install, it does it everytime I click the wad manager button. I was told that the wad manager is blocked on the 3.4u but i am unsure if that is true. Any help please.
