low temperature warning prevents charging

I'm unable to charge the phone due to a low temp warning. I read up on what might be the issue, and initially it seemed a loose connection to the NFC port might have been the problem , so it started working if I just applied a little pressure under the camera area whilst waiting for tools to open it.

However, after opening it up and checking the connection, everything was still the same except it has now gotten quite a bit worse as it wort charge at all. I replaced the NFC charging coil antenna, as most videos/articles seemed to suggest this is usually the problem, but it did not fix the issue. The connector on the motherboard does not appear bent like I've seen videos suggesting it can be, but I do not own a microscope, I just checked using a magnifying glass and it seems fine.

I'm honestly at loss on what could be the issue. I've heard the board housing the USB port can become bad from this issue, but even then shouldn't wireless charging still work?

Any help appreciated. =(
