My mom has been crying..(iPhone 6 stupid system restore button)

Hey guys! It's Bunso. So yeah we just got back from Englishtown and I didn't really want to mention this but I have to. My mom has been sad and upset and crying at nightime because she accidentally pressed a system restore button or something on her iphone6? I am also upset at this fact that my moms crying and also that the pictures and videos are gone. Does anyone know a good app or anything that can get everything back? Photos, videos, contacts, etc. without iCloud or iTunes backup? Thank you! I would really really appreciate it!
