Unknown part error doesn’t necessarily mean the phone was opened. You’ll need to get it in and checked/serviced.
You will see an Unknown Part 
message if the camera installation is incomplete or if the camera:
- Was replaced with a nongenuine camera
- Was already used or installed in another iPhone
- Isn't functioning as expected
