No wifi/ bluetooth upon reassemble. Gps is off on maps

Hi, I recently replaced the screen on my iphone 6. I disassembled the phone by removing the screen, attennea and did remove the logic board at one point to tinker and understand the hardware. The same phone did have some hefty damage.

Moreover, everything works fine upon reassembly with the exception that my phone does not have the ability to connect to a wifi network, bluetooth, and gps maps is off on both imaps and google maps.

What are the appropriate steps to troubleshooting the device? I want to resolve the issue? In most cases are bluetooth seperate issues vs. wifi and is the maps happening due to a latency on the ping with the server because it does locate me. However, no wifi IP would also address the issue.
