I dont want any display msg for display please remove that one

If the display is original/genuine then contact Apple Support at the top of this page.

If the display was replaced by a 3rd party high street phone butcher then the message will stay because they can't get genuine parts.

No one in this user-to-user forum can remove that message because it is a true statement. What was the result when you followed the instructions in the Related Article above your name on this page, that you were reading just before you posted here?
