Mini PC bootloop on Android

Hi,
TBS2910 hangs on boot with an "Android" logo animation after flashing the Android image. However XBMC boots fine. Even more: after flashing the V2 Android image from the Debug directory ( from MatrixTV sourceforge ) the device works, a bit laggy though but it boots. I've tried to flash the 4.2.2 Release image multiple times but it simply doesn't boot. Any suggestions what's wrong are highly appreciated.
Best regards.
