Buongiorno Roberto,
As written at the end of some previous post (How to: Firmware downloads for obsolete Datalogic Mobile devices) I suggest you to get in contact with your official reseller or sales partner. That would be the official path.
Otherwise you can request the FW of obsolete products by opening a support request at Technical Support - Datalogic . Fill out the form and one of our technicians will assist you. Mention this post if necessary.
Buona giornata,
