Nexus 5 [No Signal]

So I recently have been trying to figure out how to bring back a worthless Nexus 5. The phone works perfectly fine, but the main problem is it has no signal what so ever. It can't make a phone call and has no data. The SIM is valid, it's on T-Mobile's prepaid service, and I've tried almost everything.

The other owner of the device stated that they tried to flash Paranoid Android on the device, but after doing that they lost signal. He stated that the signal came back ever so often, until it just shut down completely. After knowing what the problem could be I rooted the device and flashed a clean ROM to see if that would fix the problem, it didn't. Then I reverted everything back to stock and the signal was still gone. I've tried everything that I can think of. I've searched all forums across the web and have found nothing, so I'm here.

I have included some pictures from the actual device so hopefully that helps a little. Any questions please ask.

Have you tried using a different sim card and see whether it works? If it doesn't then flash the factory images and go back to full stock and see?

Tried a different SIM, the situation was the same, no signal. I flashed the factory images and now I'm at full stock, but still no signal.

It's at the top of the 4th screen shot. It looks like it's a valid IMEI.

OP I'd call tmob and see if they have that IMEI blacklisted.

I'll call them in the morning to see if the IMEI is blacklisted.
