The hacker managed to steal my friend's facebook, because my friend saw a top eleven movie and uploaded a link, which gave the hacker access to all data on the phone.
Ι don't think it happened exactly like this.
Your friend messed up with some TE frauds like the example I give here, #17

please give more details to let us know.

Top Eleven is not responsible for that or can do anything.
Your friend must ask the help of facebook support t take his account back.
