I've had the G2x since it first came out and have always had issues with the signal dropping abruptly. However, since Thrusday, I have lost all signal to the tower and am unable to get it back. I was running EagleBlood's ICS ROM but have since done a full factory reset back to stock and completed an update via the LG Update Tool (I wasn't successful with updating the baseband any other way). Everything appears to be back to factory settings, but I'm not receiving any cell signal still.
Any ideas?
My baseband currently reads: M6600A-SCAUTNZ-2.0.9720T 1 [MAR 2012 10:00:00] MP:TRULGE_08.09.02R_MDM
When I choose Status under the About Phone menu I get the following details:
Network: Unknown
Signal Strength: -93dBm 10 asu (fluxuating slightly)
Mobile Network: GPRS
Service State: Out of service
I am also unable to enable Wifi calling. Basically the only calls/texts I can make are via Google voice on a wireless network.
I'm on the stock 2.3.4 rom currently.

I too upgraded to the new bb, and have been getting random signal drops. IDK if it's Tmo, working on their equipment, or the new base band. I figure I'll give it a week or so, as it hasn't yet interfered with my daily usage (mine drops, then comes back).
My suggestion to you, since your loss seems to be a constant, is to try using kwes 2.3.4. I had some other minor issues w/the LG release, that I don't seem to have with kwes. It's a bit more stable.
http://forum.xda-developers.com/showthread.php?t=1602798
Could just be that you had a bad install. It happens. Give kwes ROM a shot. Maybe that'll take care of it. Good luck!
Thanks for the suggestion. I'll go ahead and give that a shot, but I think in actuality something internally might be messed up.
Have you tried a diffrent sim card?

Random Signal Drops?
I have the some freaking problem, I made the thread above and I've tried a number of fixes and no dice.. Tonight I'm going to try to get a new sim. I've tried a complete reset, Rooting and removing all bloatware, and flashing a custom rom. No dice. Sometimes I drop from 4g to 2g, sometimes I drop all signal. Wifi never drops but I lose all connectivity to mobile data and signal.

Did any of you ever fix this issue? The same exact thing just started happening to me. I had to start using a back up phone to make calls. The only thing that works in wifi and I've verified the APN settings. I even took the sim card and put it another phone, which worked fine. Let me know if you find anything.

If you want to eliminate the phone as being the issue, has anyone suggested you roll-back to the previous Baseband and try using one of the CM7 ROM's that are out there?
Logic being, if the rollback gives you the same issues you previously had, then it's not a function of the baseband causing the issue.
So I have the G2x with simple mobile and just installed the latest eaglesblood and obviously I cant make any calls and texting works with wifi so is this fixed or should i go back to 2.3.4

I just got my Nexus 5 and I haven't root it yet. I notice that everytime I don't use my phone 5-10 minutes or hours, the signal will be lost and asking to reboot my phone. I can't tell when it's up or not. Sometime I take multiple reboot to get signal back up then it happens again and again. Is there a way to fix this problem without rooting? I don't think it's the Sim Card because I used it on my nexus 4 without any problem. or Just my device isn't good one. Please help!

I didn't root my phone yet, and I'm running 4.4.2 now. It's annoying to keep losing signal and it's back again. Even I have signal, I only have 1 bar compare to my old Nexus 4 has 3 bar or HTC one full bar.
I don't want to root it if its not solve this problem, I will have to return it.
There was an issue on 4.4 where it would randomly give you the "emergency only" message. You would have to turn on airplane mode and then turn it off, or reboot. But people have been saying it was fixed with 4.4.1/4.4.2.

You guys forget to mention that Google cheaped out on the antenna to cut costs. Best you can do is to flash your carrier's radio over the generic one

I'm sorry, but you're dead wrong. SO much misinformation here. First off, there is no "carrier" or "generic" baseband. There is only one baseband. Second, antenna design requires a lot of engineering to maximize signal efficiency when you're dealing with interference from such things as wifi, nfc, Bluetooth, metal construction in the phone, etc.. I'm not sure what magical material you think that cell antennas should be made of that will solve issues?
I just got off of the phone with Sprint. They show that there is an internal memo on the issue and LG is aware of it. They will be pushing an update as soon as it's ready. Sprint will also be pushing an update for the Airave to help with the issue. The support rep told me that it is an issue where the wifi and LTE radios aren't playing nicely together and causing a conflict. That's why everything seems to work fine when 3G is set as a preferred network.
It's an issue that still hasn't gotten fix as seen here.

The issue seem to be gone after couple days. I checked signal strength app, it shows same even though it shows only 1 bar.
My Nexus 5 frequently loses mobile data connectivity. Its been happening since I purchased it, but the frequency with which it happens has increased since I flashed the M1 snapshot of CM. I've since flashed the second snapshot from early January, but it has not made any difference.
This is the same sim card that ive used with my nexus 4 and my htc one without any problems, and I've made no changes in my wireless carrier.
Does anyone have any thoughts as to why this happens?
Try a different,maybe older, radio. If that doesn't help go back to stock and see if it persists.

hi.
i was this problem too, not exaactly the same, but somehow similar. I have 3g connection, the signal bar shows H and somtimes 3G, but the speed is freaking slow, worse than 2g. Initially I thought its something wrong with my phone, been changing ROMS to see if it is the issue, but no. Then I flash the latest baseband / radio, and still doesnt help.
Be reminded I am on 4G plan, but never had any 4g network ( it is not because i'm not in an area with no 4g network )
I was very frustrated and emo at the same time, thinking of RMA the phone, thought it is the radio chip problem.
but then... I called my telco, asking why I'm experiencing slow connection and bla bla, and I don't have 4g network. They keep saying my network is working perfectly, and running normally, I requested them to reset my network connection. They agreed and asked me to turn off the phone for a few minutes then they reset the network for me.
After that, everything is running perfectly.
This was 2 days ago. And guess what, I don't have any 4g connections now again. Stupid telco, I'm going to call them later when i'm free. grrr.
but please make a call to your telco and ask them.
Hope that helps
About 3 out of 5 times when I make a call when I am originally on LTE the phone call drops. I am on AT&T and when I make a call it switches from LTE to H+ then all of a sudden it just completely drops signal and thus the call and about 3 seconds later regains signal. Does anyone know what may be causing this issue or has had this issue? I am on 4.4.4 Stock with Root.
Well dropping calls isn't normal, but dropping from LTE to H+ is. VoLTE isn't really a thing yet. Calls don't work over LTE, so when you make a call it automatically drops to H+. That's normal behavior.
Did this just start happening out of the blue? Or always done that? Make sure you have the correct APN settings. If so try calling your provider and see if there's anything they can do for you.

Sorry forget to mention I knew that was normal for the drop to H+, but yes the signal drop is not. Well it started out of the blue. IS there a thread on here with what should be the correct APN settings? Also my old nexus 5 started to do this before I returned it under warranty for refurbished, then I had a moto G lte for a month worked fine, got a refurbished (due to warranty) and started again.
Here is a graph of my network coverage to show that the signal just drops.

Mine doesn't seem to have any particular count pattern, it happens very randomly, usually when attempting to call someone and once they pickup on their end, my phone would hang up. This happens maybe 40-50%of the time, can't estimate a guess, but i can say that it happens enough to piss me off. I've checked my AT&T APN, which matches to what the carrier has it set, i even went and got my SIM replaced, rebooted in safe mode, gps works, so it's not a third party app causing this. Last resort is factory reset, although I'm almost positive that won't do anything. I'm currently also running android 4.4.4 stock aosp on a 32Gb N5. Device was purchased new in early may 2014, and came with android 4.4.2 preinstalled. The random call drops issue started in early October, a few months well into 4.4.4 update. All I've found online is that i it has something to do with a missing cellular radio, but to be honest, i don't want to mess with those as that may cause further problems. Called Google, and they act like they're clueless about this issue, all they can offer is a replacement, which is nice, but to be honest, it's probably going to happen again even with the new device. My coworker has the same issue with his 16gb N5 black model. If anyone with this device trying out android 5.0 lollipop preview can chime in on if this problem still persists, would be very awesome. I'm going to wait and see when the official android 5.0 comes out, if that fixes the dropped calls problem, then N5 can be used, if not then I'm getting it replaced and reselling it, may go with the moto x+1. So either a good portion of nexus 5 devices are factory defects or this really is a cellular radio problem. Really hope that lollipop will fix this issue.
The APN only handles packet data and not voice so that shouldn't be the issue.
I would try setting your phone to 3G only for a while and see if the drops still occur when you are on 3G prior to the call.

Yea it wasn't an exact count but like 3 out of 5 says, enough that is annoys me. Tried all those as well and like I said I have a moto g lte that the sim worked in so it isn't the sim.

It's an older post from February, but seems to have the best details and fixes. If you simply search nexus 5 cellular radio issues or nexus 5 4.4.4 call drops, you should find a lot of these recalls from lots of N5 users. I'm tempted to try it, but don't really feel like sorting all my files in case i brick my device. I'm also not sure if ota update will work if i tinker with cell radios. Otherwise that's the page containing all the details you'd need including links and step by step guides. And hey if it works for you, let me know, maybe I'll try it out if it goes well for you.

Exactly, i know that's totally possible, but i wouldn't want a smartphone that has no lte and/or hspa+ service at this point in time. This seems to happen wherever lte isn't as strong or available but hspa+ is. I think the modem responsible for switching between lte and hspa+ causes calls to drop. I took note of it a couple hours ago when i attempted to make a few phone calls resulting in instant call drops. Seems to do it while switching from lte to hspa+ network. I just wish Google would stop burying their heads from the outside world like an ostrich, and get in top of this. I mean this is their flagship device until N6 goes on sale. They should seriously fix this issue or at least stop denying that they've never heard of any complaints with their N4 and N5 customers. I love this device, but a simple fix like this not being addressed by Google is not very professional, especially because it's primary function is to call people. I'm really tempted to flash those radios, but really want to see if Google addresses this issue with an official ota lollipop update.

part of the price? no. you dont see any phone more expensive because it can handle lte. your issue is with your network, and its signals around you. as we all know that the lte available can not handle voice calls. your isdue involvez lte handing off to H or 3G. thats where your network comes in.

lol, ok. the moto g variants are an exception to the majority. their already cheap price point being the reason.
those are two different devices, with differing hardware. its possible that moto can catch the signal from a little further away than the n5 can. the n5 was made less expensive because they used less expensive hardware in places. a shorter antenna being one of those places.

anyways, if you bought it from google, you can request an exchange.
I wouldn't try any hardware mod, etc as the issue is with the software. This kind of thing happens to me also, regardless of where I am or what network I'm on (tested this with a friends AT&T sim also). In the settings menu my signal strength just says "0" (kid you not ZERO) and sticks there until I manually set the phone to 3g when I go to a place with weak LTE (like a basement).
DISCLAIMER: I am only assuming this as I don't know that much about this topic, but I think stock 4.4.4 doesn't understand that LTE can still be received at worse than -115dbm and causes this fault. It doesn't matter which radio you flash (using the newest dev preview radio on 4.4.4 still has this issue, but on 5.0 it works flawlessly), what network you are on, where you are with strong LTE coverage... If you go to the wrong LTE dead spot you have this issue. It's as if the radio is saying "I'm still good on LTE" and the phone says "-115dbm isn't good we need to switch" and the radio says "I'm still connected to LTE though" and the conflict causes the signal to go to 0. I don't think it's got anything to do with the handoff from LTE to 3G either (but it might, as I said I'm no expert). -115dbm seems to be the doom number for me on LTE with 4.4.4.
Try flashing the new dev preview if you want LTE. No network = 0 bug. Hell I can even get LTE in my basement (at worse than -115dbm, of course). I had to flash back to 4.4.4 though, too many games/apps not updated yet.
Long story short, this is fixed in Lollipop. Less than two weeks...

well, try the lollipop preview, it was working for the other guy, see if itll work for you. if it does, great.
Using Ting (MVNO using Sprint network CDMA) ever since I upgraded from CM11 to CM12 I get intermittent loss of cell signal at times. Every couple of minutes, regardless of where I am or how strong my signal is I will lose all cellular signal for about 20 seconds, including voice and data, and then it will pop back up just like it was before.
I've tried downgrading to two different radios and nothing seems to make any difference. Like I said before this problem didn't occur until I did a clean flash of CM12.. everything was fine with CM11.
I've even wiped/reinstalled CM12 with the same issues.
Does anyone have a solution for this yet?
I recommend keeping your radios updated to LRX22C. Where did you get your ROM from?

From what I've gathered, it seems that sprint networks being unreliable on cm12 has been an existing problem that may get fixed in the future.

Well I fixed it.. sort of. I had tried this before but I didn't reboot the phone.
SETTINGS / MOBILE NETWORK SETTINGS/ PREFERRED NETWORK TYPE
I switched it from LTE to 3G. Looks like I might not be getting LTE coverage but it's hard to tell as LTE is sketchy at best at home and at work... and in either case I'm on Wi-fi anyway. Not a huge deal.
I had tried this before but I didn't reboot the phone after making the change. As long as I leave it on 3G my cell signal never drops. If I switch it to LTE or GLOBAL then it will randomly drop as described above.
I'll retest things after each CM12 update I install see if we get one that works!

Were you able to find a solution for this that you could share?
Honestly no..I just keep it on 3G and there are no issues.
I tried about a week ago switching back to LTE but the display never showed LTE and I definitely wasn't getting LTE speeds and the signal drop returned.
TBH LTE coverage is pretty spotty in my area and I don't use a lot of data outside of Wi-Fi anyway so it's pretty much a non issue for me.
When a CM12 snapshot is released I'll probably try again.
I should add that I dirty flash the latest nightly almost every morning. When a snapshot comes out I'll wipe and clean flash things and go from there.
Update... about a month ago I did a full wipe, going back to stock, did the network updates, etc and all was well.
Then I did a fresh install of cm12.1 and every thing worked great.. Lte and all!
A couple days later I dirty flashed a nightly and got an exclamation point and no data (Wi-Fi is fine). I did find the sprint fix flash which allows me to do the network updates again from cm (had to switch to 1X for it to work) but that only yielded a temporary fix.
I did however find a workaround. If I go to my apn settings menu and change a setting on my ting (sprint mvno I use) entry then change it back and save then BINGO! I have Lte again...
That is... Until I get handed off to another tower.. Then I have to do the workaround again.
