Well, I was applying a Drivekey modchip into my 4.0u wii, which was done successfully after a few tries. As soon as I turn my Wii on, it showed a black screen. That was when I knew it was bricked. I can use SaveMiiFrii and it shows the 4.0U at the bottom right corner. I was wondering if there was a way to update from 4.0U to 4.1J while the Wii is bricked. And if I can do it successfully, am I able to downgrade from 4.0J back to 3.2U? Any help would be great. This was a clean Wii with no preloader, starfall ,etc.
