Yet another mess up with a dm800hd, have been reading lots of similar stories and this box seems to be pretty fragile. Anyway the problem was with the sim card holder. I only removed it to check what sim number it was, it is 2.10 but I could not get the thing back in and now Ive snapped the holder. I tried so many times and I removed the front panel display so many times that now there is no display showing. The red light still flashes so the box will probably still be useable.
I can actually get the box to power up by just holding the sim card down with my hand but will have to see if there is a website that sells the holder.
So really if anyone can help with getting the display back on...and a supplier for the holder....
