OK guys, i think that I found the solution that will be PERMANENT fix of the problem with the LTE network on our G3 [ I own D855 but i think that this will be equal to all other models ]
So.... i spent hours ... many hours to find this so i hope that you will appreciate my work and maybe buy me a coffee if this help to you too.
1. I had problem, when my phone connects to LTE network and WiFi at the same time my network coverage disappeared.
2. After few days my network coverage started to disappeare with no logic... every few minutes - i have network and in a minute i dont have network and that was a proccess that never stopped.
What i tried :
1. I tried 30b kdz
2. I tried 30b via TWRP
3. I tried all different modems that i found with all this rom variations
4. I tried to go back to stock lollipop kdz
5. I may be tried something more but i wont to think more for that annoying problem any more so... that is enought
So here is what i found:
1. Simply use a Prop Build editor [ i used ES File Explorer to edit Build.prop ] to go into the build.prop and change the "telephony.lteOnCdmaDevice” value from 0 to 1. There are two lines on in the G3 build prop. Make sure both have the value of 1. Then save. Then reboot.
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
First make a backup of your build.prop file !!!!
2. Deleting the file LTEconfig.apk works sometimes. The file is located in the folder: / System /app
Just copy it to other location and delete the file and restart your phone. I said sometime because with some combination of roms and kernels and radios it helped me, but not in every variation. You have to try yourself.
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
First make a backup of your LTEconfig.apk file !!!!
3. Next thing that i found is that editing the build.prop with this values have a massive effect too :
ro.telephony.default_network=11 or 13.
ro.ril.def.preferred.network=11 or 13.
ro.build.target_country=AU or COM or to your country code.
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
First make a backup of your build.prop file !!!!
4. Try to Disable Fast Dormancy. You can do this by simply open the hidden menu in your G3. This can be done by simply dial *#546368#*855# on 6.0 D855 or 3845#*855# on 5.0 D855 [you will have to find the codes for the other variations of G3]
so hidden menu > Modem Protocol > PDP Setting > Set LG Fast Dormancy > disable
This fix will basically have to be done everytime you/me flash a new rom or update but it works!
So... i have no problems anymore with this network issues
If someone find something that can be done more permanent than this, i will be glad to hear and understand but for now this is OK i am sure because we can use our phones as phones.
some people (including me ) have data icon missing in stock kdz and lose sim options too after rooting :/ are they any solutions for us ? I searched for 5 days :/

http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/ try to download stock kdz or tot .... some older version like 10a for example. Flash it with flashtool 2014 or lgup but first in twrp advanced wipe and wipe everything... then when you start your phone "from beggining" try to OTA update to lollipop.... i hope that this will normalize your problem. I am not sure... you have to try it. You should restore backup from when you were stock ot efs partitions just in case before flashing new kdz...
Write if it helped because there are many people out there having strange problems with network connection.

Ok, its not lost time in fact... this means that you dont have hardware problem its software related and mostly in 30b version that you have installed.
In fact my last rom flash was with file downloaded from here http://devtester.ro/projects/lg-firmwares/ as thurasisyein said.
I dont know why.. for no reason... i just coughn`t find 30b 16gb kdz with fast speed of download here in the forum and i tried.
Thanks for this thread!
I had no 4g/lte connection after i flashed MM KDZ, and no matter what rom i installed it didn't work, after i tried these fixes i found an old backup to restore, after that straight to 4g.
Now installed another rom via twrp and 4g sticks. For me i think it was a regional issue. (on 855) Denmark.

OK, try to insert your sim card into another android device. Remove your sim card while your G3 is into airplane mode... insert it into another android device and wait to connect to 4g... when this happened put it back to your G3 and airplane mode off and see if this will make things better.
Hey guys, I have an AT&T branded LG G3, unlocked, under a mexican network provider (TELCEL), every band is supported by the phone and I'm using their SIM. I'm currently using Fulmics 4.2 Rom, but even on stock rom, since I received the unit, whenever the LTE signal was too low, or I made a call, the phone would drop the signal and switch to 2G. The problem is, once this happens, the phone remains on 2G and won't change automatically to LTE. I have to turn it off and on for it to recover the LTE signal. Will this fix the issue? Or do you think I have a faulty unit? Thanks!
4g icon missing
Please Help My LG d855 On Stock 6.0 4g icon missing but data is still working fine , but in another rom like AOSP , 4g icon is appear and fine , Just in Stock Rom my 4g icon is missing , But Data is fine , Just a icon , Anyone Help , Thanks
This is what I was looking for all month, thanks OP. I use a h2o sim for mt vs985 and every time I booted up my phone would complain about a non-verizon SIM. Also, I would only get 3G.
Changing the target carrier to ATT and default band to 4 in these settings resolved this after a reboot. The error is gone and I now have 4G. Thanks for telling me about this!
@mccloud90, thanks for this thread. My problem is slightly different (it it can be called "problem" at all).
Using an app called LTE Discovery, I can see that modem always chooses LTE Band 3, which is more power-hungry than other ones. For example, in my country, LTE (4G) Band 20 is much more power-efficient, but, for any reason, modem never chooses it. I can force the selection of Band 20 thru the hidden menu, but this comes with other annoyances, like the fact that I cannot do or receive telephone calls. In the other hand, using Band 20, I feel much less power consumption.
So the question is: are there any way or workaound to tell the modem/sytem TO PREFER one LTE Band?. Maybe some build.prop configuration or a .sh script?
Thanks and, yes, I know this is not an easy question =). I just wanted to know your opinion.
After installing Marshmallow using the KDZ firmware, LTE was not working with a Cricket SIM card accessing the AT&T Network. I then made a phone call and received an automated text from Cricket to provision my phone and this fixed the LTE data connection. The SIM card method posted by Varna above may also work to generate a provisioning request from the carrier which could resolve some connection issues.

Model: LG Optimus G Pro F240s
I was on a custom rom when I started getting no network so I followed the best method to get to stock by a user (using LG flash tool).
I was successful & got back to as stock as possible, Problem:
the IMEI is showing as unknown, only when SIM is inserted !
WCDMA hidden menu settings change & save when there is no sim but with sim inserted they do not change & IMEI is shown as unknown !
Please help.
I have searched a lot but no progress!
I read that if any of you give me the stock efs images for efs for a Optimus F240s then I can restore them back.

IM SO HAPPY RIGHT NOW!!!!
Ok , im a noob but i did what others said "impossible"
There was no logic in my method but i didnt gave up.
I used FlashTool.1.0.54 with a Brazilian carrier KDZ(my current Carrier) . - No sucess (i flashed a 989 kdz in my F240L, but i did that to try to recover modem and baseband data)
After that, as i had no sucess, i flashed the korean kdz ( F240L10v from the LGU carrier) but i did not wipe cashes and user data.
When i finished to flash the f240l my signal was back, but i got several crashes from the rom (i clicked "ok" more than 100 time XD ) but managed to enter system (i was kinda blind cos evething was in korean language) and perform a factory reset.
NOW EVETHING WORKS FINE, THANKS LORD !!!!
My advice: Dont give Up, try everything even if u tried it already...try again and again.
I wish you luck !!!!!

You have to be on download mode and your battery needs to be 100% fully charged, otherwise the update will not go thru. Good luck!:good:
Joining the pack here... Please help. Trying to download the Stock ROM for v10V right now. Phone came with 10Z originally or so I think. That's what comes up when I check the IMEI through browser anyway. Tried to put stock 10z and issue unfixed.
Edit:
Cannot download v10V... link from lg-firmware not working.
Anyone who has a copy of it?
Fixed it!!! Ahahahaha! :laugh:
Step 1: I installed Stock E980h Panama Firmware. Download it from lg-firmware
Step 2: Installed Stock Original F240L 10z Firmware.
Step 3: Jump, Roll and Jump again becuase it's working now and I dont know why. Ahahahaha!

Hi everyone!
I need help again, I flashed Vanir ROM (http://www.emccann.net/nuclearmistake/VanirAOSPNightlies/geehrc/) but it didnt work, so I flashed it back to Cyanogenmod 11 but forgot to put the sim card back during flashing, but the thing is, after i put the SIM back after flsahing, the SIM card is being detected (it says "No Service - Globe" [Globe is the name of my provider]) but there is no signal. I tried reflashing back to stock ROM... then restored EFS backups... its still not working ("Service Disabled"). I even did a complete wipe, including system folder and reflashing to stock ROM... but its still not working.
Also I tried playing adb earlier because i tried copy/pasting a rom to my phone. i tried adb kill-server, then adb start-server, adb usb, adb devices... did something on these commands affected this issue?

I even reflashed the KDZ...still no network :\
To simplify things, check the threads here in Q and A section. There is a method to bring back your lost network service.

for LG E975 original Firmware i gues its from US version...... unlocked already via some tools from Google.

Hi,
After using the KDZ method, my LG G3 cannot connect to the network. I get the "service disabled", "no Service" and sometimes it connects to the operator for some seconds. It is important to say that before the flash, the phone was working fine, and connected normally to the network.
Troubleshoot already done:
1 - Firstly, I flashed using the D85520B_00.Kdz file.
2 - When I realized that the error, I thought this might be a version problem, so I downloaded D85510e_00.kdz version and re-flashed downgrading to 4.4.2. However problem remained.
As a comment, I also noticed that it changed from version D855 to D855V.
What should I do?
Either its a problem with the modem or you lost your efs partition
What does it say under IMEI? Does it still show your phone's IMEI

Still, that sounds exactly like a corrupted-EFS problem. But with corrupted EFS, in most cases, IMEI is reset to 0... If you have a backup, try to restore it.
If no or if it still doesn't work, try to flash an other KDZ (with modem inside) or just a standalone modem.
Also, check APN and that kind of software things

Hi.
the IMEI SV is set to 00. The IMEI is XXXXXXX... If I go to Network, it will be searching for service. Actually, I can see the network, but I cannot connect to it. I get the message "Unable to Connect to Network". I have already tried 3 kdz versions, without any success.
Just so we're clear your using CSE flash with the kdz right?

Hi did you find the solution...? If yes plz let me know I have the exact same problem...
I have found a lot of threads and people reporting this issue. Bought a D855 32Gb from China that has this problem...
Phone tries to get signal a couple of seconds and then a cross.. and so on..
I tried everything I think, I passed for all the bricks the phone can do: Automatic Reboot / Boot Loop / Fast Boot / Security Error / Factory Reset Status 2 / Dead (QHSUSB_DLOAD) - I can help anyone that has any of those problems : )
In one of the flashes my phone turned to D855RE, similar case to other people, also the message "Current version is not available for user. Can't find matched cust for NT-Code mcc/mnc".
Please if anyone was able to fix the problem report here, there is a lot of people waiting for the answer 20 threads in different networks, I will post the solution in each of those. Thanks!
Hi
I suggest you download the LG phone from app and this will give you which Stock Rom is for your phone. Then you need to search For it and install. I have a D855 Taiwan version and that is what i did and now on Stock D85520W.
Hope this helps.

Got the same situation. Tried a lot of modem, upgrading to MM, then downgrading to LP, then to CandySix and CloudyG3.
Also tried changing in Buildprop. still Service Disabled.
I was having a problem trying to find the modem for my D851 here on XDA. There were many plainly listed for D855 and other models of the G3. I am using Paranoid/ASOP 5.1.1 Rom and I accidentally flashed a D855 radio. Rookie mistake, I know... And thought I backed up the modem along with the system files. Well I didn't and lost my imei, apn, signal and all... So while searching and again not obviously placed easy to find I read a thread and found one, flashed it, and it returned everything to normal without having to flash back to stock rom and blah blah blah... From what was listed, this for L 5.0 and up.
1. Boot phone into recovery, preferably TWRP
2. Flash the modem zip DOWNLOAD: https://www.dropbox.com/s/xz26z91hej9ryz3/LGD851.20B.MODEM-iNb4TMO.zip?dl=0
3. Reboot
I didn't make the radio, nor take any credit for its creation. I'm just trying to make it easier for T-Mobile D851 users on Lollipop to find incase they have deleted or lost theirs like I did...
I am not responsible for any issues or problems that may be encountered by using this.
I hope this help those in need like it helped me... Please let me know...
Im currently having a major issue with the lollipop update. I had my d851 with t mobile and I wouldn't lose lte when I would make a phone call... I currently switched to metropcs and now when I make a phone call I lose lte and my signal drops to 4g. I tried everything... APN, restoring the phone, called metro like a thousand times and nothing. Any help would be greatly appreciated.

Flashing the 30D modem seemed to help quite a bit, the signal will drop to 4g while you're on a phone call but the data is alot faster. Give it a try, it worked for me.

Well, I went camping over the weekend and of course the phone dropped service again. The cell signal was weak and the data was almost non-existent. Luckily I brought an old phone, re-activated it, and was good with LTE signal. My question is would flashing a different modem help? I have the LG-D851 with SW version D85130e so I assume that has the 30e modem. Is that correct and would the 30d modem be better? Thanks.

No idea. Could be something else (mechanical) causing the issue. 30e is the latest for our phones. You can also drop it down to 30d & see if it is any better.

That's what I was hoping to do but was trying to see if there was a way to just install the 30D modem instead of loading the entire phone with the older SW version and having to re-install all of my apps. I downloaded the modem file but after doing some research I couldn't figure out the procedure to install it. I saw a few videos about a TWRP recovery but I prefer not to root my phone. If I have to root it in order to get it working then I will...I just wish I could figure out what the issue is. I saw a few other people mention issues with the LTE setting defaulting back to WCDMA/GSM (which I experience) and they said the 30E modem could be the issue. The phone was just wiped clean a few months ago before I bought it from the previous owner.

yeah without having root, your options are limited. If you own the phone, I would say go for it, if you are leasing it, then take it back to where you got it & tell them it's reception sucks.
I own it and bought it second hand. According to the previous owner he didn't have any issues with it but who knows. I assume if I root it and load the 30D SW I will have to load everything from scratch? Is there an LG backup program for this phone? Thanks for the help.
Restore from SD card
From any home screen, tap Apps.

I have the TMo version (D851) & the first thing I did was root it & install a custom ROM to get rid of all the Tmo crap that is stuck onto it. ugh! I don't use my phone all that much for calls, mostly emails data & music playing, so losing the stock Wifi Calling function wasn't an issue for me. Currently on the OctOS Nougat weekly builds, tremendous ROM, great battery life fast & smooth & decluttered. Since you already own the phone & do not have a warranty, you've nothing to lose here. Do some reading in the threads on how to do it, you'll be very happy once you see how much better your phone can be. You put on it only what you want to put on, less junk, less memory hogging.
Hi, this a weird problem for my new e980, i flashed properly the e980 at&t rom, and now i dont have signal, i tried flashing modem.img from here and nothing, still no signal, also tried to flash the telcel kdz and nothing, my IMEI is ok, but i dont have signal, is like is trying to finding signal, sim card is ok, working in other phone, please, somebody can help me please?
Come on guys, hope one of you can help me, this is happening after flashed a 5.0 lollipop for F240K, I think, I converted my e980 to F240K, but now the signal isn't working even his own baseband, I really need your help guys, please!!!
Have you tried going back to stock jb?
Start from jb. It's the most stable version we have.
Then you can root and install twrp from flashify. It's the most up to date recovery we have. Forget about the others because they can be buggy.
After that you can choose whichever room suits you. But I'd recommend SlimLP...

I tried, no signal, I updated it manual via the software to KK also for test and nothing.
PD: I tested the E989 modem from another guy and now I have signal, but only WCDMA and GSM, I don't have LTE, also the 3G, H and H+ aren't working properly. Help please

You'll probably have to flash Telcel firmware first (E980H variant I think, not sure if Telcel or something else), then AT&T firmware to get your network back. Also, you must do a full (CSE, if I'm not wrong, haven't started LGFlashTool in a while ) flash, with complete internal wipe - "update" flash just changes system, boot and recovery, not modem/firmware images which are ones you need... Also, you MAY try flashing madmack's modem (it's ripped from AT&T E980 firmware) before flashing OEM images...
I really don't understand why are you people messing with modem images and other stuff like that at all... especially without backups. Last year I had to mess with nearly 10 phones from my friends/associates, because they got their modem/efs images broken/corrupted trying to flash something which isn't made for their device...
Actually did it, not working with AT&T rom, Tried with telcel then I flashed AT&T rom and nothing, nothing is working for me, tried the madmack modem file and nothing works. still no signal
Have you done a FULL flash? Are you sure you have E980 variant (difference between E98x variants is literally in modem firmwares)? This more looks like you have flashed wrong stock firmware.

Shady, I really apreciate your help, thanks for answer, my friend sell me that phone, he said is a E980, but after see the imei is a E981h version for argentina where I live, before flash the korean lollipop, my 4G works perfect, now I dont have signal, I tried the E980 and well, not signal, I tried E981h too because is a variant from south america too and maybe can work and actually is the real stock firmware for my phone, no signal, nothing.. I tested the phone with 2 firmwares from E989 (1 from Brazil the other one is from CHILE) and is working but only WCDMA 3G and sometimes the signal drops and I only have 16gbs for storage.
More clear, this is my summary.
1) E980 Firmware from AT&T, Telcel and Panama = No signal
2) E981h Firmware for my E981h, Stock Retail and Movistar Telefonica KitKat and JellyBean = NO SIGNAL
3) E989 Firmware from Brazil Retail and Chile Claro = Just WCDMA and signal drops.
4) Custom ROMs? Just tried the CloudyGX 1.0 with E980 patch and E988 just for test = NO SIGNAL
I can't find the problem, also my phone was in the service before this and was totally useless for them, but I think these guys wasn't too profesional for be honest, i'm pretty sure.

Custom ROMs won't do a thing because they are using firmware images on your modem partition.
IMEI says it's E981H Argentina, but it doesn't work with that firmware? What the hell... What's written on your phone's case? There is a model mark on the housing, after you remove back panel. I have E988 (Open TW variant), markings say E988/E989. In the end, ask your friend where he/she got it, that may help identifying it...

He sends me the box also, is in my house now, I'm working at the moment, he got the phone in a normal store, is 100% original, let me check the model inside of the phone.
EDIT: its says "E980_0805"

This may be risky, but you already flashed F240K firmware and kept your device alive. Have you tried flashing E988 firmwares?

Is my first time with an LG Phone, is a really weird problem for me at least, Never tried with a E988 Firmware, what firmware is good for flash? just asking because you have E988 and probably you know which one is good.

Weird, E988 is basically international one, should work everywhere. Check preferred network type in network settings.

Yes, works but only GSM, no WCDMA and 4g, but I flashed the argentinian modem and i get a low WCDMA, is like the signal is very low in that rom, but not 4G or GSM.
Yes, I checked the preferred network in #*#*4636#*#*# and only works with WCDMA also tried the change the band in that menu but was useless, signal drops and 3G isn't working. Also tried in the options of the phone and the same result.
Tried the 3845#*988#* for configurate baseband and no luck. :l this is real a good problem, but I can confirm, the E988 at least works the argentinian modem with WCDMA but signal drops fast.

Have you tried to download your firmware from lg website?
Try to Google it. There might be tutorials telling you how to do this using your imei number. Then, you'll find the correct firmware.
Remember, you should use an LG website link to be secure in the use of your imei.
Edit: try that link
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=<MYIMEI>
Note that you have to substitute MYIMEI for your imei. I'm not sure if you have to keep the brackets. So try both possibilities and see which works.
Edit 2: now I remembered all the steps.
Once you insert the imei without brackets you will have info on your firmware. Notice that in the central area of the page you have a link that ends in .kdz
Copy that link and insert it in your browser's address bar. That will prompt you to download your correct firmware.
That firmware will most likely be E98120X... Or the KK version...
After downloading it, change the 20 in the link for a 10...
Doing this you should be able to download the JB version. This is the most stable version for our devices (the KK version has a bug on the modem that keeps the device awake when it shouldn't).
If you succeed, flash the JB version, the one with the number 10 using the CSE option in the flash tool.
After that, you should be up and running and able to flash any custom rom without the risk of signal drops.
Oh, have in mind that if you want to use 4g you will have signal drops. This is also a bug of our devices. It works best in 3g. Every time you have to reboot, change from 4g to 3g, when signal is back on change again to 4g and you'll have it working with few hiccups...
Don't forget to keep backups of your firmware and report if you succeed.

Hi, the 10 version isnt available in that web using my imei, the only one is from carrier, Telefonica Movistar, I tried with that and not luck.

Good. Now that you know the exact "name" of your rom you can Google the JB version (the one with number 10).
