Uninstall the theme first, then install Summerboard and then reinstall your theme. I had installed some themes and forgot to install Summerboard first and my themes didn't show up, so I had to do it that way.
I tried to install the old and new version with my installer and and it says "package download failed" can anyone tell me why or how to fix it? Im trying to install it so i can get video wallpaper. thanks everyone
