Screeneo 1590 reinstall image

I don‘t know how, but it seems that my father has crashed his screeneo 1590. it boots but that‘s it. No Os seems to be installed or boot so I‘m searching for a rom and installation guide or a cable recovery method to reinstall the system os because of the missing menu I don‘t think that the firmware upgrade via sd card will not work as it is necessary to select the menu according to the manual.
