How to get out of Resque Mood? How to load my 7080 with a new img? Sorry for my dissapointing feelings...

I have boght this expensive DM7080 and found some problems. I can not change img. I only get RESQUE MOOD http;//dm7080, very tricky machine with very few possibilities, as I have found.

Sorry that I paied so much money. I should hav been satisfied with my DM8000, DM7020HD and DM500HD and finally Vu+Duo2.
