Hey there,
An Unknown Part 
message will appear if the display installation is incomplete or if the display:
- Was replaced with a nongenuine display
- Was already used or installed in another iPhone
- Isn't functioning as expected
An additional message might appear that says "Apple has updated the device information for this iPhone." This means that Apple has updated the device information maintained for this iPhone for service needs, safety analysis, and to improve future products.
