mobile

I bought an used HTC ONE M7 for a very cheap price. The condition of the phone is very poor.
The phone has the purple tint camera and is very scratched.
The most annoying thing is that the front housing plate is screwed by a screw, which is very unusual. I attach some photos to this post.
The question is if I buy a top replacement plate for the phone, how am I going to mount it as I cannot find any tutorials to do so.
