I have accidentally factory reset my friends iPhone 5s and they have not backed it up since the middle of 2016 and have now lost a lot of work, photos and contacts. Is anyone able to help/advise on if it is possible to recover the deleted data from the iPhone. we have not started the phone up again as (in theory) we are hoping that the old data is still there until new data is add on top to replace it. Please Help
