Hi,
I have serious connectivity issues with my Nexus 5.
Most of the time I am only picking up 2G signal, sometimes the connection drops compeltely. However, I had a very unstable 3G/H/LTE connection for a few minutes sometimes in the last days.
This started after changing the battery and upgrading from Cyanogenmod 12 to 12.1. Unfortunately I did both changes at the same time, so I am not sure what caused this problem.
The following things I could rule out/test:
- Another phone (Nexus 4) picks up H+ with my sim
- My phone doesn't pick up 3G/H/LTE with another (working) sim
- I have checked the connections of the both cables running alongside the battery, I also checked the cables itself.
- I fiddled with the apn settings, also I never touched them before and everything worked fine.
- I have updated the radio image.
The one thing I couldn't try is flashing an older cyanogenmod 12, because I have no backup and couldn't find one online.
Does any of you have any ideas what I can do?
I would be really thankful for any kind of help.
Who is your carrier :/
I probably should have added that in the first place.
My carrier is T-Mobile in germany.
I have the same problem. Also i'm tryed flash Android 5.0 and Android M, in stock i have Android 5.1.1. Who khow how to fix this ?
I have no solution yet. The next thing I want to try is to roll back to Cyanogenmod 12, but I guess I am going to build it myself because it seems to have vanished from the internet.
I do occasionally get LTE, but it is very unstable and doesn't work most of the time.

I followed directions to wipe everything as suggested in this post:

Was using Alfa 13 just fine, but on Alfa 17 I can not get cellular data to work. Confirmed my WAP settings are correct for my carrier.
My baseband it says its a i9020xxkf1 and everything else on the phone works. I can access the market, wifi works, account sync if i have wifi on. I have doubled checked every possible setting. But it will not bring up a data connection over the cellular radio. It even takes calls over the radio. Just no data connectivity.
Any suggestions or reasons why this is occurring? I can easily swap back to an older nandroid image of alfa 13, but I would really like to get on a new version etc.
(Also, I would have made this post in the right dev section, but i lack 10 posts to gain access to it.)
Have you tried removing and replacing your SIM card ?
Also, check if your data counter has a limit set on
You could also manually configure your APN settings with your carrier's settings
Unfortunatly I have done all of those things. It doesn't even attempt to connect to data. I sit at 4 or 5 bars of signal and it never even connects to EDGE/3g at all. Yet if I flip back over to my older image it works flawlessly.
i have also problem with version 17, but i can't post it to developer forum (newbie here)
problem is that i can't hook on any network, no calls no messegas, i'm using croatian tele2/t-mobile....sometimes it connects but still nothing, no calss etc.
also problem (not so much a problem but a solution) when i installed ROM it went to bootloop, all you have to do is remove battery and power up again, and voila, it works, same problem happened when i installed gapps (same solution worked, everything installed from CWM latest version)
there were also posts regarding cwm not stiking after installing cynogen, i had no problem with it, i have latest cwm 5.0.2.3 (think so), sticks like hell tried couple of roms, still sticking
cheers
I have the same problem here... ICS 4.0.3 and my 3G stopped to work.
also tried new 18 version, still no luck, i'm staying on cynogenmod 7 (GB), only ICS version that worked was MUI but i don't like it very much....

It has been messed around with a fair bit. Various methods have worked for different people. YMMV. I myself had such an issue with the stock FW (of all FWs...).
This happens on every Lollipop ROM I have flashed, no problems on 4.4 ROMS. I do clean installs, do not restore anything from Tibackup. So basically what happens is I will randomly but very frequently lose all data and cell service. Like once every three minutes frequently. It only lasts about 5 seconds at a time. The signal bar triangle will have an exclamation mark in it (see attached example). I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option. I have read some threads about this exact same thing happening on Nexus 5 after Lollipop update but they are old and it seems to have been fixed with an update. Does anyone have any ideas about what is going on? I'm on TMO in the US and like I said, it ONLY happens on Lollipop ROMs it does not happen of Kitkat.
I read this as sort of an explanation as to why but nothing as to how to fix it. It is driving me insane.
I'm in the same boat, I cant make calls with hangouts or with Dialer or it will disconnect. I haven't seen a solution yet. I've tried every ROM I can, but it keeps crashing. drives me up a wall. I want to logcat it, but having issues while at work.

Only discussion about this I have seen is in the Nexus 5 forums, nothing in OPO
Any insight to this would be greatly appreciated.
Come on guys, am I really the only one with this issue?

You're not alone, I have this as well but I don't get the exclamation mark but instead the triangle appears completely empty, as if I have no signal at all.
anyone know a way to fix this awell? i flashed the new lolipop alpha modem and still same thing if not worse
The only time this has happened to me is when I toggle Wi-Fi. It for this every time, but have no data issues otherwise. Seems to be when switching between ip addresses. Are you possibly between towers or roaming on another network? May be the issue, but I can't say for sure. Running the lollipop rom exodus, no issues at all.
EDIT: also what baseband are you guys on? I thought I saw something similar and someone flashed a test baseband and it fixed whatever issue they were having. Link coming shortly.
EDIT 2: just now noticed the list above mine about the alpha modem and it not working for them. If anyone else needs to try however, link is http://forum.xda-developers.com/sho... work for some and not others.

Does anyone know if we can flash the CM11S modem on CM12?
Go to Settings -> More - > Mobile Networks. Make sure all the items are set correctly.

In OP "I delete and re-enter my APN, turn off wifi AND the Scanning Always Available option."
Same issue here. Running SlimSaber using alpha radio.
Same problem on two OPOs here, both running Temasek CM12
Anyone found a solution yet?
I have the same issue on CM12, BlissPop and Validus ROMS.
Strangely I do NOT have the issue on Euphoria.
Think it happened after I flashed the Alpha L modem.
Tried flashing an older CM11S modem, but no luck...
Hi,
Sorry for the noob answer but anybody tried settings>mobile networks>preferred network type and set it to 3G? I flashed a new rom from stock CM and noticed that I was experiencing signal trouble, I checked my status and the signal detected is LTE so I changed my network to 3G and network signal improved. Downside is that you cant use LTE (but thats ok for me since here in our country, LTE signal is still kind of limited)
Zino same for me. Ever find a fix or a rom that doesn't do this?
OP here, it's strange that all of us have this issue, the same issue that came up on the Nexus 5 thread when L was first released but know one else seems to have any knowledge of it. I am almost certain it doesn't have to do with our carriers but rather something software related.
I'm also suffering from this issue, until now the only way I knew how to fix it was to wipe the cache in recovery which takes ages!
got the same problem :<
I have a similar issue. I use t mobile in the USA and LTE works, H+ works, but 3g shows signal and won't load anything. No idea how to fix it.
It seems I have managed to solve it by myself. I have loaded factory image of 44S, preformed OTA upgrades and it seems the issue is gone.

Hi, Last week I had my phone connected to power bank over night with "Sleep as Android" turned on. In the morning I got my wake up alert but I was unable to wake up my screen to turn it off... so I had to keep the power button down and shutdown the phone.
After that I have faced boot loop (phone worked fine previous evening).
I have tried rebooting phone couple of times but nothing worked so I have restored backup of last CM11s from TWRP (I was running on CM12 nightly during the crash). Phone booted up poperly and I thought everything is fine however after couple of hours I noticed my phone is asking me for my PIN so it has apparently rebooted. It appeared that it is rebooting every couple of hours and after every call (like 5 sec after call ended)...
I have tried restoring other backup but I was facing the same issue. I have done clean install of current CM12 nightly and got the same...
Facing that I decided to clean my phone completely... I have backed up all my data and did wipe and format of everything of everything I could from TWRP. Then via fastboot I have been tring loading YNG1TAS17L 64GB (from here) by flash-all.bat file. After loading bootloader I have received message <waiting for device> and my phone got hardbricked...
I managed to recover it using this guide.
Then I loaded TWRP again and installed COS 12.
On that point my phone started working stable but after a while I noticed that is started losing cell signal. Sometimes it was just for couple of seconds and sometimes it lost it for good (while tring to hardcode cell operator I was getting "error while searching for networks" and I was able to restore connectivity after couple of reboots).
I decided it could be radio/modem related so I have applied full firmware. No go. Loaded CM12 nightly - the same, loaded that modem from oxygen again - no go.
I have tried installing latest BlissPop, Mahdi ROMs and Oxygen and still facing the same issue.
Tested SIM card on other phone and it works fine, tested other SIM card on my OPO and still the same issue so it is phone related.
Getting the following in logcat during time phone is unable to connect to cell signal:
Code:
05-31 11:57:36.265 D/GsmDCT ( 2457): [0]isDataAllowed: not allowed due to - SIM not loaded and not NV subscription
05-31 11:57:36.265 D/GsmDCT ( 2457): [ApnContext:mms] getApnSetting: apnSetting=null
05-31 11:57:36.268 D/GsmDCT ( 2457): [0]isDataAllowed getRecordsLoaded=false
Anyone has any idea what could be a reason of this issue and how to fix it? At this moment everything is working fine except phone calls and Internet over network operator (Wifi works fine). Thanks in advance.
UP
Anyone has any idea? I believe I have narrowed the problem down a bit. It seems 2G/3G is affected only. As long as I'm in LTE range the connection is stable (that explains why I noticed the problem after few hours when I left home).
I have played a bit with hardcoding band and noticed that LTE is running stable (with GSM Signal Monitoring app). When switching to 3G it is dropping every couple of seconds. The strange thing is that 2G is sometimes affected and sometimes not... When switching LTE->2G it seems to be running pretty stable but when switching from 3G->2G it is acting the same way as 3G.
were you able to fix it?
I went through same experience except that I can barely connect to 4g, 3g 50% of time. Tried many radios but none worked.

OP updated the post with how it was fixed. Sorry to bump the thread, but thought I'd inform spx that there was an update. Glad it worked out for you OP, I've saved this in case it ever happens to me, and good luck to spx. Hopefully someone puts this info in a sticky so others can try that if they are stuck too.
I fixed it by reflash raido of xnph52q found here. The zip contains more than the radio firmware.

I flashed it before but it didn't work. The only difference is I used TWRP 2.8.6. I remember reading somewhere online that 2.8.7 has issue with OPO

Where is the 44S that OP used? I have something similar happening with my phone. I revived my phone from a hard brick and now it's not connecting to the cell network. Wifi works, IMEI shows when SIM is inserted, no EFS partition backup (I didn't know that was a thing to do until it was too late).
FWIW, my current build is KTU84Q and I'm running CM-11-20141008-SNAPSHOT-M11-bacon
The Wi-Fi on my wife's unrooted Nexus 5 (Sprint version) which was upgraded (via OTA) to Marshmallow last month suddenly stopped working last week. The slider would get hung while moving from Off to On (like it was trying to turn on) and therefore was not detecting any available Wi-Fi signals.
After trying many things, I eventually did the extreme and did a full factory data reset. No dice. Still not detecting anything.
Figuring it might be an OS issue with Marshmallow (given we're seeing a lot of forums indicating Nexus 5 issues based on Wi-Fi with both Marshmallow and Lollipop), we downgraded the OS first to Lollipop and then all the way back to KitKat (4.4). Still not working. At initial phone setup, the phone is not detecting any available WiFi signals and gets hungup trying to find networks for me to choose from - so I end up having to skip this step.
Any other tips out there on what I can try? Is this a sure sign of hardware problems? Don't think my wife's phone is under warranty any longer (have had it slightly over a year, I think).
PS - Now I can no longer even upgrade the phone (OTA, at least) from 4.4.4 because my phone is saying it needs Wi-Fi to download the update - with no option to do it over my data plan.
I'm in the same situation and it appears to be a hardware failure. The wifi chip can't be replaced so a motherboard swap is required.
You can upgrade to the latest stock ROM by flashing the entire ROM from a command prompt in Win7.
Plot thickens
So, I figured out a way to get the OTA's over LTE (by manually changing my phone's date up a week). While going through each OS update from 4.4 KitKat to 6.0 Marshmallow (about 5 or 6 rounds of them) my phone briefly was able to detect WI-FI, I believe during set up at 5.1.1 Lollipop - and I was able to get on my home network.
Probably should have just stopped updating after that, but definitely was not detecting anything after that. I lost it during one of the Lollipop updates - well before getting to 6.0. Not sure if WiFi was actually working well or not.
Maybe the chip is in the process of failing? Not sure but it seems like you are having better luck than me.

I wish. Don't want to go through all those steps again after doing a clean wipe to have a fleeting glimpse of Wi-Fi.

Hi, pagalbengal. I'm having the same problems right now, and I wanted to check with you to see if there have been any developments with your situation over the past month. Still hopeless? Have you contacted Google tech support? Do they still even support this phone? Thanks for any info.
You guys might want to try reflash the modem firmware.
Couldn't get my wi-fi to work so I replaced the motherboard. Every stock and custom ROM I tried could not enable wi-fi.
If I'm understanding correctly none of the current roms work on Sprint's network. Is that correct?
I've tried lineageOS and couldn't hold a signal so if there's one that works please point me in that direction.
Thanks.
I hadn't had any luck with ROMs on Sprint either until today. I decided to restore my TWRP backup of LineageOS 14.1 official, then I re-flashed the bootloader and radio from the most recent stock build (I had been on 4.4.3 to test something). The device was not active on my account at the time, but when it booted up, I got an alert from Signal Check Pro that it had an LTE signal, and the LTE indicator was on. So then I signed on and swapped devices to try to reactivate it, and immediately went into carrier settings and tapped update network settings. I got an alert shortly after saying com.android.phone had stopped, but it appeared to work, and I had a signal and LTE indicator. There was a Lineage update showing (May 17), so I downloaded it (over LTE) and installed it. Everything has been working so far, both before and after the update: voice, LTE (all bands), SMS, MMS, and RCS. So I really didn't do anything different, it's just working now.
Note, I have had SMS problems on every stock build starting with the first 6.0.1 build, and all security releases after it. I haven't had any problems on any older Android version. What happens is it works fine for a while, but at least once a day. SMS stops working until I reboot or update network settings. That's why I installed Lineage, trying to determine if it's a bug in Android or the radio. So far, no problems, but it has only been a few hours.

LOL it course the SMS bug struck after about 24 hours.. except this time it took a couple of tries to get data working again, and SMS wouldn't work again.. I knew better.. back to stock again..
