Can explain how you have configured the box, from the beginning, is it 2 tuners, freeview and so on.
Basically it should be image, language, configure, tuners, set up autobouquets, dont scan yet, set up epg ie openepg. Then scan under bouquets. You have a bug and in the end it may be the box but you have to do a clean install and set it up correctly dont restore anything.
Then if you get bug you now have to try another image like openatv then if error send box back.
