Admin thanks, the fix you suggested was successfull;-).
There was no need to flash the SSL84J, I just lunched the Japhar Flasher and then the OpenPLI March 2024 and now the box is up and running.

I had a small problem connecting to the Dreambox with my usb to serial adapter, since I do not have a pure serial on my notebook, but after installing the newest drivers, I was able to enstablish the connection via COM15 port and Flash the image.

Thank you once again for your very appreciated support!

Regards
