Front camera doesnt work after motherboard swap

Hello, on iphone 16 plus i recently swapped motherboard to icloud locked phone, (I took camera from same phone where was motherboard), it works but on all components expect rear camera it says they are locked but work, but face id and front camera dont work. It just say issue. I tried restoring via dfu mode with apple devices app but it kept giving me error 53. I managed to restore with 3u tools but it didnt fix the issue. I also tried using icloud locked camera, but it just said its locked and didnt work. Is there any way to fix it ? Would buying another genuine icloud unlocked cam fix it ?
