I own an E986 for one month, I bought it from Greece but it must be from Germany. My problem is that after rooting and installing many custom roms and stock roms I dont have 4g signal. I have tried everything, hidden menus, 4g switchers, flashing modems from allover the world just in case something works, flashing back to stock with lg flash tool, I tried stock 4.1.2 and 4.4.2, I erased APN's and added again......and many many more. Can anybody please help me? I will try any ideas, one last thing, the signal of the mobile carrier is depending only on the modem I install or are there any other parameters that I should try to flash. Thanks in advance!!!!

If you've flashed back to a stock TOT/KDZ and still have no 4G, then it seems like it cannot be any software setting other than APN configuration, and if you're certain that's right, then it could be worth it to try a different SIM card.
What else could it be? If you've flashed a correct stock image for your model, then you've ruled out software issues other than configuration, and if it once worked with the same software configuration (APN settings, etc.) then what else could it be but hardware, something tangible?

So what do you believe? Do you think that I have a hardware issue? But how on earth is it possible to have 3g and H signal but no 4g. I have flashed every stock rom for my device through kdz method but I haven't tried the tot method, do you believe that this might be the solution? I have even bought another sim card from my provider but no luck, should I try another provider? Phewwww I ask a lot I know please forgive me it' s that I have never faced a problem before that I couldn't overcome......

KDZ is sufficient. I don't see how TOT would make any difference. Maybe you could try just to familiarize yourself with the method. I don't see how that could make any difference, but maybe I'm more ignorant that I realize (this happens often enough).
So you've had 4G on that phone with that same provider before? WIth the same plan? If it's not software, and not hardware, then maybe it's to do with the carrier? I think you can be pretty safe that it's not software if you've got a stock image flashed on there, and if your APN settings are spot-on. That would leave:
- SIM card
- Phone hardware
- Carrier
- ?what else?
If it's not software, as in if you've got a fresh stock image flashed, then what else could it be but hardware? Maybe I'm missing something.. dunno.
Have you tried the SIM cards in any other phone to see if 4G works?

To tell you the truth I haven't tried the sim to another phone because I don't have another 4g phone, I have contacted my carrier and they confirmed that I have 4g signal. Who knows, I cant understand how it could be a hardware issue since I have 3g and H signal, do you know if apart from modem is there anything else that I could flash in order to have better signal reception? For example flashing kernel or something else....

Maybe visit some cell phone shop and ask if you can ram your SIM into one of their phones for a minute, to test.
If you've flashed a KDZ, I don't see what else you could do, software-wise, on top of that. Have you ventured very far into the hidden diagnostic menus? I know there's tests in there for most everything, ones that show if you've got a 4G connection and exactly what detailed connection info is available.
EDIT: Oh, you can look into your service manual here. Maybe you could pull a MacGyver, yes?

I followed your advice, I tried my sim to another 4g phone and it works perfectly, I even bought a sim card from another provider just in case but again no luck, 4g signal wont show on. The hidden menu is something that I have discovered but dont know what values to change, I just checked that lte is enabled. My only hope is to find the original stock rom for Greece named e98610c.kdz I believe to flash it and see if it works, but I cant find it anywhere. My phone is from Germany though, another option I have is to find a second stock rom from Germany different than the e98610i.kdz, I have seen an e98610a.kdz, but I wasnt able to find and download it. Any help would be very nice, but thanks anyway.

Hallo again, one more question, is it possible that I have flashed a modem that is capable of 4g but in bandwith that my provider in Greece doen't support?

I don't think so. If you've flashed back to stock with a KDZ/TOT, then you're golden.
Who is your Grecian provider? What are your current APN settings?

My Greek provider is named Cosmote and my APN settings are the following
Name Cosmote Internet
APN internet
MCC 202
MNC 01
APN type default
Hope this tells you something, looking forward to replying me :

Did you find your e986 Greek stock image yet? Just curious. I swear it sounds like a hardware problem though. Dunno.

No unfortunately I couldn't find anything, I now flash some 4.4.2 rom from e988 just in case.....
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.
Tap Settings.
Scroll down to 'DEVICE,' then tap Backup & reset.
Tap LG Backup service > Backup & restore.
Tap Restore from backup.
Locate and tap the SD card backup.

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.
I have been scouring the internet for a while and cannot seem to find a way to revert my tablet back to stock. I tried the Lollipop firmware for a while and wanted to restore the tablet to possibly sell it. I can't find any method to recover it nor the files. The full model number is SM-T520NZKAXAR. It is the wifi only model. Can anyone help me please? I also currently have the TWRP recovery on it.
Thanks.

Thank you but I've looked there. I can't seem to find a match for my model number or any USA model. I read somewhere that the cellular south file will work but I'm a little hesitant to try flashing it. Mine is the WIFI only model.
If that were the case, it would either be a T525 (LTE), or possibly a T521 (3G). So anything listed as 'SM-T520' on Samfirmware should be OK. Having taken a look the US is not listed there. I have seen the Cellular South (XAR), as the possible option. But I doubt it has anything to do with any 3 ~ 4G connectivity, as the T520 has none.
It's possibly worth mentioning that these 'codes' (i.e. XAR), isa CSC Code. e.g. retail location in most cases. So assuming XAR is the USoA then this would be your choice.
Just one thing that you probably already knew, but is it really worth downgrading back to stock? The Knox Flag has already been blown. So NO KNOX on said Device ever again. Which would be about the only reason I could think for downgrading back to stock. Which IMHO would be a touch immoral if you wanted to resell it to someone who otherwise wouldn't have a clue.

def not mine was in deep sleep mode and i didn1t know it and now i use temasek ,it`s out of warranty ofc but bugs and error and lags from bull**** sa,sung apps are gone. cyanogen 13 modded flies like 5 times more than stock i play on tablet do a lot of stuff never had any problem in almost 1 year i can do offline backup a lot of perks.at some point when s3 will come i will sell it like this 32gb sd card leather case,i love this device.so no point going back to stock ever i always flash every new device
Thanks. I may give the cellular south file a try someday. The latest Cyanogenmod is working well. I was having problems with one of the older versions. The touch screen was acting goofy sometimes.
Have you tried https://samsung-firmware.org/?
Cellular South *is* the USA version. If you want to restore to US stock version, Cellular South is what you need. I don't know why they name it that way.

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...

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...

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.

I'm using E988_V10 firmwares for TWN variants, best base for my device, especially since I'm using AOSP/CM roms

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.

Good. Now that you know the exact "name" of your rom you can Google the JB version (the one with number 10).
Good Morning,
So this is the story, I was suddenly having issues with Cell service people were not hearing me I felt like I had to reset the phone and wipe it all so I thought I might as well ROOT it when it came to downloading the firmware I was a bit lost did not know what was the correct one was i threw out the box,
I flashed one but still have this cell issue I feel like its not using all the bands... I have Tmobile and I do not know if the issue is I am flashing wrong firmware.
So 2 questions
how would I know if I am flashing the correct firmware?
And how would I know if that is my issue ?
Please Someone Advise.

I would test another carrier first, or the same carrier in another area. Also test with different people in different areas. This is most often an issue on the carrier side, not the device.
So my advice: make sure your issue is the device. Only after that we can talk about flashing another ROM.
Thanks @arsradu for your quick reply Its definitely not the carrier I just am not sure what the problem is, I was thinking each firmware has its own optimizations for the bands it should use,
I bought it on amazon USA
And currently flashed
TROIKA_RETAIL_10_QSBS30.62-17-13_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
I tried using LMSA to restore my phone to factory settings and it gives me an error I wish I can just go back to stock clean.

Assuming you bought a US model, which works on all major carriers, your version should be RETUS.
With the bat file that was provided here in the forum, you should be able to fast boot flash it.

It can be the ROM, as well. In my experience though it’s usually not the case.
Anyway, what’s your device model? Is it xt2013-4? Did you make a backup of your original ROM so you can restore it later on?
Also, what is the error you get when trying to use LMSA to restore?
Yes my model number is xt2013-4 no i did not make a backup I uploaded a screenshot of the error message. and I guess I will try reatilUS I tried the simple retail option the last one not sure what retail and retail us differences are,

RETUS with the above linked bat has worked fine for a XT2013-04 I have worked with, I assume it would with yours too :good:
I cannot speak to the assistant error though, never used it...
Side note: don't forget to add the code line for the 10th chunks to the bat.
Does Any one know what are the differences between Firmware's that are made for this phone ? for example
AMZ
Retail
Reatus

AMZ is the Amazon Ads model,
Retail can be US retail with different bands.
Retus is what I flashed in the past on a US phone that worked with all 4 carriers and it never had any issues.
