I Don't know what I did but i plugged it in and out and pressed some button for a long time and than after 30 mintues it just boot up again even running with the new BootMii. So everything is alright again. Don't know how, but it works again. So problem solved Thx anywayby Wii1989 - FixMii
It doesn't make any sound. Nothin happens when I plug it in. And its not the socket or anything, I already tried everything. I just plugged the cable off while the wii stucked and now nothin is workin anymore. The guy there who posted the 3rd answer got the same problem I don't know what happend but really nothin is workin anymore. :/by Wii1989 - FixMii
Well, here is the problem. I installed Wii Brew like described after that I just went on "exit" and a black screen with many many many numbers came up. My Wii somehow stucked than and after a while i just pluged it off the socket, because not even the On/Off Button did work anymore. And now when I connect my Wii to the socket nothin is workin anymore, not even a light comes up at the on/off buttoby Wii1989 - FixMii
