I was careless and I chose the wrong image file to flash to my Dreambox 800HD (clone) sim 2.01.

Now when it powers on it gives me a message on the OSD

Look at www.dm7020.com
Erro! No CA found

I tried using DreamUP to flash a proper image, but I can't.
It recognises the Dreambox and it says "uploading flash loader"
Then it says "upload completed, waiting for acknowledge"
and then nothing.

Can anybody help me please?

Thanks a lot.
