Try finding Nokia Software Recovery Tool 6.0.5 although mine may only be working as installed it a while back, got a prompt to use in "Offline mode" and it recognised N9 as Product code 059J1W1.
Another little known fact if you can find Nokia PC Suite v7.1.30.9 this will read "Contacts" & "Messages" upon N9, but you must ignore all prompts to update application.
