No cellular signal - Phone broken?
Hello, recently the screen on my nr. 1 Nexus 5 broke, (does not work at all) and I though I could just switch motherboards with my 2. nexus 5. When I had switched motherboards, and put the battery cable into the motherboard I saw the backlight on the screen turn on, and then instantly off again, and the phone refused to boot. So I though, what the hekk, I'll just reinstall everything on my nr 2 nexus 5. I switched motherboards so they were back at their original phone. And I booted, but I didn't get any signal. I tried to return back to stock, with this
guide, and with Android 4.4.2 (KOT49H) as stock rom.
I'm back to stock now, but i still got no signal, and the phone does not give me any notification if I remove the simtray, or if I insert the sim.
Any thoughts? What can I do to fix this? Or have I just been really unfortunate and have broken two phones?
The phones says the Baseband version, imei, nettworkstype and network is unknown, with the simtray in
I did the following, and it fixed some problems. It now does say my imei and baseband version (M8974A-184.108.40.206.23), but network, networkstype is still unknown. My signal Strenght is -83dBm 15 asu. And the phone detects the simtray activity, and if the sim is inserted.

It says that only emergancy numbers are available, but when I tried to call one of them I got no buzz-tone, and it said "calling"...
Tried to manually write in the APN, did not work, installed twrp custrom rom, and tried to advance wipe cache. did not help
