I successfully installed the homebrew channel. Then I tried launching the homebrew browser app to download some emulators. During the launch, the screen said an enception (DSI) error occurred. And it just stayed there. I couldn't turn the system off. Even after holding down the power button. So I unplugged it. Now when I turn it back on, I get a message on the gamepad saying that it cannot connect to the Wii U console and to turn it off, move closer to it and turn it back on. I've been doing that but it still won't connect. Also there's nothing on the tv screen when this happens. Just a black screen. What do I do? I hope it's not bricked.
