No service after fixed broken screen

Hey guys, hopefully I'm not too late and this can help many others. I had the exact same problem. Replaced my screen and then had problems with No signal, stuck in roaming, emergency calls only.. What I did was with the phone still turned on I took the back cover off (pulls off a lot easier from the headphone jack). With the cover off looking at it from the back, there are 2 terminals on the top right (to the right side of the camera) you must take a screwdriver or any conductive metal and touch the 2 terminals together for about 10 secs (you will see the signal strength come back on the notification bar. That will act as an antenna and jump start the reception. Test it out for a minute or so and if all is good, put the back cover back on and you're all set. Hope this helps and works for the rest of you, worked for me!

"So Check it out guys my girl brought home a Neuxs 5, and well guess what the problem was... you're right 'No Service' with a SIM in the tray. So I went out and did almost everything possible people had been recommending left and right on different forums, blogs, YouTube vids, etc... you name it. Nothing worked (rarely after doing certain things it would connect but the connection would never stay on the network), untill finally 5-6hrs later I came along some post suggesting hey and if your flashing your radio file be sure to give KRT01B a try, seeing how the poster thought it was a very stable release. So after trying everything I was like !&&* why not, I had even checked the Canadian blacklist at this point and the phone was clean, so I figured !&&* lets try to flash this old ass radio file..... Holy $@$*... The Nexus 5 Connected And Was Holding The Connection, Finally I Can Get Some Sleep.

Worth a shot, there has been many software problems. Might as well try before you toss it. Good luck!"
