So i changed my broken display of my iphone xs with local display, after change my both camara is not working also flash is not working, Camara app is all black and crash it not even try to start camaras.

the shopper say it was your phone issue not display issue, But it was working great until repair.
He said to me that it can because of my phone has only 64gb and i need to reset my phone.
But i don't have any backup and i have stolen device protection is on so i can't do anything, i can't even open my apps like wp,instra without faceid.

I don't even connect to my pc for backup it is keep saying "faceid required to continue because stolen device protection is on"

I don't know what to do, if somebody help it will be so helpful.
