We are sorry that we couldn't support this website over long time and not support U4 boxes with XBMC.
We would not support XBMC anymore. It was tog big project. so we can't follow up anymore XBMC.
But we will release with new Android Launcher with XBMC.
Please wait until release new firmware with eOn Launcher.
We hope that we can keep to support U4 product.
U4 support team.
