[Q] CM11 total loss of signal - Nexus 5 Q&A, Help & Troubleshooting

I flashed the latest nightly yesterday. Everything was great. Then last night I had a total inability to make or receive phone calls. I thought it might just be an install issue so I did a reinstall and unfortunately same resuts. Im using radio m8974a-2.0.50.1.13..... is this the issue. It works perfectly on stock 4.4.3 and im rooted. I like the rom but need my phone to work. Any suggesions?

I'm back to factory and all is good. The problem comes when I flash the nightly.

Did you have no signal or just did it not recognize your SIM?

If relevant, does your carrier require anything special? (e.g. Sprint users need to flash a fix for APN or something, I wouldn't know as my carrier doesn't need anything)
Was it working at any point in time while on the ROM, or was it like that on first installation?

I use at&t it worked at first for about an hour then stopped. I think it has something to do with the new 4.4.3 stuff. 4.4.2 was fine.
BTW this also happened to a few people on another custom ROM when they went from 4.4.2 to .3. They had to revert to stop also.

Maybe it's just the specific ROM? I suggest you try another first. I have no issues with 4.4.3

All fine for me, although I did a factory reset after applying the OTA (which I do after all OTAs)

OP, out of interest, are you talking about 3G speeds, WiFi or both?

I think you need to be at least on an unlocked boot loader.
then you can fastboot flash it directly or install a custom recovery and flash a .zip version from there

CM11 Unable to update profile/PRL (Sprint)

Hello again!
So my latest issue is that I can't update my PRL or profile under carrier settings. The options are there but nothing happens when I select either.

I've already reported this. They should be fixing it. I would in the meantime just flash a stock rom and update then go back.

PRL/Profile are not ROM dependent so there is no reason for it to not stick. Try again; make sure you update both before flashing back to another ROM.
it wont even run for me

I've never been able to update PRL and Profile on any non stock ROM. I'd recommend keeping a stock nandroid backup to restore to when you need to update.

Sprint LTE

I have a new N5 and its unlocked and rooted. I get LTE just fine on the stock rom but when I flash any custom roms, LTE doesn't work. Even when I restore my backed up EFS on the custom rom, LTE still doesn't work. Anytime I nandroid back to my stock rom, LTE works fine. Any ideas or help will be appreciated.

Did you flash Sprint software? It could be the APN.
What sprint software? forgive me im new to this. I did make a backup of my apn of my stock rom and restored it when i flashed a custom rom, but it didn't make a difference.

I think there's some extra APKs you need to add to custom ROMs.
I fixed the issue. I unrooted and returned my phone back to stock. Then I found a sprint. Zip that you flash with custom roms and that worked.

I'm on Sprint and I've flashed most of the custom roms for N5 with zero LTE issues. Which rom did you flash?
There is no custom sprint software this is a Google phone.

Check the APN settings. On AT&T I have to tweak my settings to get LTE instead of H+.

Its a zip to flash after roms that sets the correct APN settings for sprint. I can't remember the thread I found it in though. But it was for the same issue I was having with my LTE/3g switching.

The reason I am searching through posts is this: my 3G works fine. But when it kicks over to LTE... Nothing happens... In a minute or two I may get 4 mbs or something pretty good and then nothing again. I need it to actually work. My wife has the same issue on her S4 and she is stock. It switches over to LTE.... Nothing. I have LTE off mostly. Steady slow 3g is better than no progress on LTE.
update profile
Should provide the correct settings in the custom Roms assuming the creator added the update profile features. I know cm does

[Q] Screen is black put still on (get calls, vibrates etc)

Hey guys!
I've had my phone for a couple of moths and just a few days ago it started acting weird. When i lock and unlock the phone my screen is black, but the phone is on and "fully working". If someone calls me, the phone vibrates but the screen is still black. Only way to fix it is to reboot. Anyone had this issue or know any solution?
Thanks

Its just a Franco issue as far as I know I've had the same issues using r40 using the stock kernel or any others its fine no s.o.d
Sent from my Nexus 5 using Tapatalk
Nice...
Glad I saw this thread. I was thinking it was a kernel related issue. I'm rooted stock with Franco. I was having the issue a few times around r40 - r44. Updated to r45 the other day and haven't had any issues since.
The issue disappeared as soon as I updated to r47. Thanks, guys

[Q] Just received 4.4.3 OTA - Android version still shows 4.4.2?

Hello,
I'm completely stock, no root or anything on my Nexus 5.
I just received the 4.4.3 update (T-Mobile) and downloaded/installed. It asked for a restart, I said ok, and then it restarted.
Afterwards I checked the Android version under About Phone and it still shows as 4.4.2.
Any ideas? When I check for updates, it says I have the latest version.
Thanks!

I ended up just sideloading it. I shouldn't have had to, but weird issue regardless, especially since I'm completely stock.
