How I can confirm that my box is not a clone?

If possible, I would like to try the DreamUp for Linux.

Is it working, where I could download it?

My Dreambox is no new. It had a software from 2011, therefore I wanted to upgrade to a newer image.

I tried with an image called: openpli-enigma2-11.3-dm800se.nfi

The result was the error "no ca found".

How I can confirm that my box is not a clone?

It has a text: Model: DM800 HDse

S/N AB0515100026049

In a green stamp there is a black horse and the text: SIM FERRARI inside

I can send more information if needed.

Where I could find the program DreamUp for Linux?

The links in this thread are not longer working.

I have tried to flash my Dreambox, the result was "no ca found" and it don't boot.

What I can do to be able to flash it?
