first open opera mini.If you lack it you can download it from this link.Then  go to menu>settings>advanced>Protocol.After this change the protocol to HTTP.Now go back and enter the address 0.facebook.com .And your job is done.Log in and do whatever you like.But note that in this way you cannot see in pictures or videos.It is my first post so go easy on me.
