Okay, so I've been searching the net for days and to no avail. I installed the new Cyanogenmod on my Nexus 5 and found it, well, awful. It kept hanging, restarting etc. Now when I tried to revert back to stock, I downloaded the image file from developers/google/com/android/nexus/images, and there's no 4g. No mobile data whatsoever. I can call, the Wi-Fi is working, but no mobile data. I've tried factory resetting, installing a different radio zip etc. When I install Cyanogenmod again, the 4g works again, but after going back to stock nothing again. Any help?

Wow, this is stupid, but after trying everything, including running every new stock rom, I tried installing the 4.4 (KRT16M) AND IT FINALLY WORKED. I'm gonna leave this up for anyone in the same situation as me.

Well, would you guess, the problem's back, but from a different angle. After installing 4.4.0, and letting the device upgrade itself to 4.4.4, the data worked perfectly. Now I tried to install the android L developer preview and again no data connection.
Does anyone have any idea if it could be a regional issue or something? I tried flashing older radio zip files but to no avail, now back to 4.4.0 :( .

I lost connection all together last Saturday. I flashed CM 11,Friday and all was well. Received a call Saturday, it rang once then lost connection. Had to reboot four times to regain service and that was short lived. After any call incoming or outgoing, I lose service. All APNs are present. WiFi works. SIM alert when SIM is removed. SIM works fine in my N4. Did a complete tear down and it's not hardware related.

If you loose signal might be a radio problem, still if you have signal but no connectivity try with the new APN, android (CM, stock unless carrier stock) had errors in the APN list for my carrier and I had to manually add it each time I used a new rom for several years.

im having some trouble with my radio also, it will work fine for a bit, then out of no where, ill download an app and it the signal will just go blank, not grayed out, but blank, ive tryed many different things but not apns, would anyone happen to know what T-mobiles apns are?

Edit: I just now noticed in my list of apns, its set to Metro pcs, and theres a few Tmobile apns, what should i choose?

i think speedtest, advanced download manager, the first time it happend, i had just flashed slimkat 5.10, i set everything up, and i used the LTE quick tile to turn off LTE, my hole signal dissopeared and my phone crashed, i had to restore to stock to get it back. now it does as i discribed erlier.

man, i just got off the phone with a robot from tmobile customer service. she had me turn the phone off and pull the sim card, she told me she "refreshed" my service on her end and the problem was "gone". ya, its not.
