An iphone 4s at iOS 9.0.2 is asking to upgrade to iOS 9.1
The problem is that we know it's activation locked and we don't have control of that Apple ID.
Since I cant disable it if I can't remember a password. So if i update my iphone this will not block it or leave the phone bricked?
(The back story if it matters is problem when iphone was buyed from second hand user forget remove his accaunt, all was disabled but i make stupid thing i enable Find my iphone and now i cant nothing to do.)
