Got given a P20 Pro to replace the LCD as it was not working, and was completely smashed on the back.
Replaced the screen, all starts fine, WiFi works but says no service.
Antenna is secured to the frame properly.
Coax cables are snapped in firmly and are not mixed up.
Tried resetting network settings
Cleared Cache
Performed factory reset.
Any other ideas?
Thanks

Sounds like a broadband problem on the logic board

Fixable if someone can microsolder?
Customer isn't too fussed, as he just wanted the photos off the phone originally.
It is very strange that it happens to every person that do a screen or battery replacement....
This happened to me after screen replacement. Take your sim card out and flip it 180 and put it back in (face up to face down if that makes any sense)
Mine worked after that!

It happens after a battery replacement. These phones must detect the replacement battery. The phone just gets a poor signal indoors but works fine outside. I think I'm going to put the old battery back in and see of it makes a difference and I'll report back. I only replaced the battery because I was replacing the back for a customer.

Definitely, it is due to chinese bad quality chasis. In this phone, chasis is mostly the antenna. In my case, I took only the screen carefully grom chinese copy chasis and then glued the screen to original chasis. Now has fully signal and probled solved. Hope this help to someone, I was a lot of hours triying different things and my client was angry
