Last weekend, I placed a good ol MS AM+ screen on an iPhone X, then the phone suddenly quit being able to connect to Wifi nor Bluetooth. I’ve done about a hundred of these repairs on this device, yet I’ve not had this happen before. Thoughts?
Things I’ve tried: Resetting Network Connections Updating Device Replacing all 3(!) Wi-fi antenna cables.
It could possibly be a motherboard issue, that’s about all I could guess honestly.
