On the Sim2 boxes, the back button loads a Sim2 SSL, so it will work only if you have a sim2 in the box.

For the loading of the box, did you proceed as explained on the PDF posted ?

We had a similar problem with a DM800HD box, and it was staying at DM800HD on the DreamUp, nothing more and Johnny verdict was that the Flash chip was damaged.
