Yes thats clears thing out quite nicely and I'm even more disappointed.

In fact I know now that I spend 400 bucks on a device which is hardly useable as an development unit for fun hacking. No factory images is a nogo for me and I'm evaluating right now if I won't sell the whole thing on ebay after christmas.

Perhaps you should've disclosed this information earlier. I'm really disappointed now and feel a bit ripped of because I asked this question several times and haven't got an answer until now.

But I think the 400 bucks from customers looked so nice you wouldn't bother telling the whole truth.
