Stolen iPad recovered, but stuck on "Lost Mode".
My mom's iPad was stolen several days ago, and recently recovered. While it was missing, I put it on "Lost Mode", but now the iPad is offline, so I am unable to take it off "Lost Mode". The iPad says to connect to iTunes, but iTunes says to enter the passcode on the iPad, which is impossible, because the iPad is locked. Is there any way to recover her Photos and other info? If not, is it possible to restore the iPad?
