Hi fellows, I recently acquired a LG G3, an astounding phone, but then I realize it doesn't connect to 4G/LTE network. I'am an advance user and I' double checked APN, Carrier Service, and all configuration staff, also I had read a lot about troubles people is having with this, but my trouble is less common, I had the 4G/LTE option available and enabled in Mobile Networks menu, but my phone just doesn't connect to 4G/LTE it just stays in HSPA. Well, I' have tried the most common solutions and none works for me, here is what I've tried:
1. Go to hidden menu: 3845#*855# -> LTE Only -> Modem Settings-> RAT SELECTION->GSM/WCDMA/LTE auto (this just restore my HSPA and cellular connection when solution 2 fails)
2. Go to hidden menu: 3845#*855# -> LTE Only -> Modem Settings->LTE Band Selection (here I switched to every band, some give me a Success other Failed, nevertheless I got no signal service unless I do solution 1)
3. Change build.prop telephony.lteOnGsmDevice from 0 to 1( it changes it, but after reboot it comes back to 0, nothing happen )
4. Renaming LTE Config apk and rebooted(I rebooted then the it says the phone is upgrading and after that nothing happen)
Now I'm sure it is something related with the phone region and my current location because my firmware has suffix ASEATN (Asian)and I'm living in Ecuador currently, but I'm skeptic about the risk of flashing and changing the region.
Can anyone give some guide or advice about my specific problem, I'm willing to do advance user staff. Thanks in advance!
These are my phone specs

I have exactly the same problem.
I'm from Peru and the model is D855P. I used to have 4G LTE when I first bought it, but after installing CloudyG3 (Lollipop), I was never able to connect to 4G again. I have the option but it never really connects. I have to set it to 2G/3G only.
It's curious that when I traveled to the U.S some weeks ago and used an AT&T SIM, 4G LTE worked perfectly and back in my country, it does not.
I tried changing LTE bands using this method http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 but still not working. My carrier uses LTE Band 4.
I've also tried factory restores using the PC Suite. The original software is restored but 4G still does not work.
Any help would be appreciated!

Okp I let you know..the process es really easy...you spent more time documenting than doing it really...I think I'm going for a Cloud G3 Rom, which is more familiar and stable with the device.

Thought i'd start this thread so australian owners of this phone can help each other out.
I bought this phone & had it shipped to AUS at a cost of about $290 AUD. The phone is to replace my Galaxy note 2 that got smashed.
At half the price i originally paid for the GN2 it seemed like a good deal!.
However when i got it i realised it is actually a refurb & its is also pre-rooted
However I can't get it to detect any sim that has been installed, tried TELSTRA 3g & 4g sims - Also tried Optus sim, no detecting of sim.

Hi. As I see, your G PRO is Korean. Such as F240 is for Korean versions. However, it may have been converted to Korean for the KitKat ROM. You mean SIM is not being detected, that it says SERVICE DISABLED? If so, Try this:
1. Flash KDZ of Mexico from here: http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW826486573210987654321/E980H10A_00.kdz
2. Then flash your desired KDZ.
This worked for me so, feel free to try it!

I think the phone is definitely F240, well that's what the stickers says on the inside & what is reported by the IMEI checking link.
So maybe not a good idea putting E980 firmware??
EDIT: constant message on screen saying "check the USIM card is installed. cell phone function is limited"

Even though the SIM is inserted it displays that message?
Yes, i tried two different sims. same message.... the phone doesn't seem to recognize any australian sim
These are the freq available on different Australian mobile networks
2G
2G, other wise known as GSM, is standard on almost all phones (except CDMA phones in the USA). Most new phones come with quad band GSM support. A quad band GSM phone supports 850, 900, 1800, and 1900MHz.
2G is old technology and provides a fall back position when 3G coverage is unavailable.
Australian 2G bands:
900Mhz (Telstra, Optus & Vodafone)
1800Mhz (Telstra, Optus & Vodafone)
3G
There are several 3G networks operating in Australia. 3G frequencies are usually specified as UMTS/HSDPA or WCDMA frequencies on the mobile phone specifications.
Australian 3G bands:
850MHz (Telstra, Vodafone) – Exclusive 3G band
900MHz (Optus, Vodafone) – available in most metro areas on Optus, with both Optus and Vodafone re-farming the 2G 900 spectrum in regional and rural areas
2100MHz (Telstra, Optus, Vodafone) – Exclusive 3G band
4G
Australia is currently using these LTE bands (LTE bandmask in brackets):
2100Mhz (B1) FDD (0000000000000001) – Telstra (3G spectrum)
1800Mhz (B3) FDD (0000000000000004) – Telstra, Optus, Vodafone
900Mhz (B8) FDD (0000000000000080) – Telstra, Vodafone?, Optus (utilises spectrum previously used by 2G)
2300Mhz (B40) TDD (0000008000000000) – Optus (Vivid wireless spectrum)
To follow late 2014:
2600Mhz (B7) FDD (0000000000000040) – Telstra, Optus, TPG?
700Mhz (B28) FDD (0000000008000000) – Telstra, Optus
This is what the F240 Optimus G Pro supports.
GSM-1800; GSM-1900; GSM-900; UMTS(3G)-2100; UMTS(3G)-1900; LTE(4G)-2100; LTE(4G)-850
CHECK YOUR PHONE HERE: http://checkphone.australianphone.com.au/
So looks likes optus is the best bet for anyone wanting a F240
However I cant get any sim to detect so it must be a hardware faults, any good way to test hardware?
so no one in aus seems to use this phone.... can someone tell me why?

I have the same problem. I bought F240L version for US$127 ( Extremely Cheap). The phone initially worked with my Optus Sim. However, it developed a Wifi problem (wouldn't connect on second day of ownership) so I flashed F240 Kitkat stock rom (And F240 Lollipop stock ROM) using LG flash tool2014 to see if this fixed wifi (It Didn't) and stopped phone recognising the SIM. I can't find a KDZ version of F240-EUR. So my phone now has neither wifi or network. I think the phone is fast and looks great but I think Australian's should avoid it as the network problem seems common if phone is updated. My son also has one which works ok on Stock Jellybean. I tried to restore a CWM backup from his phone on my phone but CWM reported a MD5 error and aborted. Anyway I have probably got my US$127 worth of fiddle value, but hate to see such a lovely phone reduced to toy status only.
Additionally: I have managed to restore F240-EUR Stock rom but the Network and Wifi still don't work. The Network did work originally on this Rom. I don't know why it now doesn't. AVOID THESE PHONES IN AUSTRALIA.

Hello,
I am using LG Optimus G Kirean version for over 6 months. Phone/Battery life everything is great. Recently official kit kat update was released and now it is running KK. The only problem is that as I am using it in Pakistan I can't use Data Network or 3G. I talked to my network operator and they say phone must be converted to English rom then it will work.
The problem is that I am really a noob at this and don't want to brick my phone. So is there any easy and low risk method to convert my phone to English version without losing signals or any other problem. If possible please give a detailed step by step method as I am really new here.
Here are details:
F180-K
Android Version 4.4.2

That is answer from someone at the network operator who not know the anything about the phone or data in general.
You just need the setting for data network to make it work Data & 3G will work on the same Korean rom however no operator video call because that feature is specific to Korean operator in the Korean rom.
There are many guides available in the forum and making Backup of your phone is a good idea before doing anything
Well I have done settings multiple time and settings are 100% correct however data or 3g doesn't work. They say that this phone stores settings in Korean at the backend and network can't read it.

Basically i did setting my operator apn to make it works (calls and Data) in Indonesia. Currently im using korean version F180L.
Sent from my LG-F180L using XDA Free mobile app
Thanks a lot. I was about to give up. Then I tried one more time for APN and it works now
Check for 3G bands in 3845#*180#
You should be GSM 900/1800 for Calling and
UMTS 2100 for 3G
And setting should be WCDMA preffered or GSM/WCDMA

Hi Everyone,
I hope you guys will be good.
I have flashed cm13, Bliss pop, XenonHD etc.. on my LG G3 D855, cm13 and Bliss Pop were better from others in my opinion.
Unfortunately 3G isn't working on every ROM I have tried I have searched the issue a lot and tried tons of solutions including suggested here:
http://forum.xda-developers.com/lg-g3/help/cm-13-nightly-3g-problem-t3264442?nocache=1
Entered into hidden menu *#*#4636#*#* tried to change preferred network type to GSM, WCDMA and whatever was suggested in some forums.
Its very unfortunate that nothing worked for me now this forum seems my last hope.
Just to confirm I have now installed the stock Firmware (Marshmallow 6.0) before that it was on Lollipop and on both 3G was working perfectly fine.
So, Its not the network issue or something. It seems to me the ROM issue.
Just a little addition I live in Pakistan. And supported band here in Pakistan for 3G is 2100MHz
Thanks in advance for any help.
Regards,
Nadeem
My HTC just came back fresh from repair and decided to install Lineage OS and the latest GApps as fast as possible.. Phone works great, but I don't have any signal even thou my SIM is there... I have Vodafone in Spain, please help!
So I started tinkering around with the phone... So It's not the network that it's not working, it's actually the LTE.. I do get 3G+ but every time I enable LTE it's a no go... Please help!

Hello,
I will try to keep this short and sweet.
I am on US Mobile using the black sim (verizon towers) and currently have a LG v30 that no longer can make calls due to Verizon shutting down cdma beginning of 2023.
I have my brothers Lg G8 ThinQ phone purchased from US Cellular. It is now rooted and I followed this guide to add LTE support for other carriers:
[GUIDE] [NO ROOT REQUIRED] [EPIC UPDATE] How to add VoLTE support for other carriers to the G8 (and other Qualcomm powered LG devices too!)
This guide will not work if you are running Android 12 :( I'm gonna keep the intro simple, been a longtime user here on XDA, and recently I found that my T-Mobile LG G8 only supported VoLTE and VoWifi on, you guessed it, T-Mobile! So I did some...
forum.xda-developers.com
I used the mbn files provided from the guide and loaded a few of the US carriers. Upon putting in the sim, and trying to change settings to get it to work, I can only get data to work but texting/calling (in/our) does not work at all. When attempting to make a call, the 4G indicator also disapears. I contacted US Mobile thinking it maybe was a APN issue but they stated on their end that the phone is incompatible.
Not sure what else to try. My only hunch is maybe reloading mbn files from a downloaded KDZ but I have no clue if that will work (also to download 5 gigabytes takes a few days for me).
Any help is greatly appreciated.
attached is both the phone info and a snapshot of PDC of it showing VZN got activated on the phone with the sim in it.
EDIT:
For if anyone else comes across this. My solution was to crossflash (using the guide in the LG G8 fourms) the open market KDZ and I went with G820QM30c_00_NAO_US_OP_0103.kdz as I had android 11 already installed and that it was the A11 version download the most from here: https://lg-firmwares.com/lg-lmg820qm-firmwares/
I did have to correct my FTM partition but that crossflashing guide links to some good solutions.
*Note: Only issues that I have seen with the version i flashed is i cant add an APN. The button is just missing so had to install an app to view it, and when receiving gifs, they turn into pictures only. both things I can live without as not volte works on verizon (us mobile).
So, which rom would normally work with that carrier? I'd guess the us open version would work, why not just flash that on the G8? I've no idea what bands us cellular rom supports, but I'd trust the correct rom (for the current carrier) to work rather than following that thread to 'add bands'.
I used that thread once, didn't accomplish what I wanted. Not to say it doesn't work, I didn't try that long. But have flashed numerous roms re diff carriers, that always does what it should re correct bands.
Frankly, I am not sure if my reply will be helpful, and I know nothing about the US Mobile specifically, but just wanted to comment as an owner of a G8 originally from the US Cellular. Feel free to ignore this if it seems irrelevant...
I bought my phone second-hand with an original US Cellular A11 stock ROM. Later cross-flashed it to the Canadian Open when A12 became available. Rooted with Magisk. I am using the phone on the Rogers network in Canada. On both ROMs I have no issues with data, voice and text - everything works, including concurrent voice calls and data usage.
A (possibly) dumb question - have you tried the original US Cellular ROM as is, before diving into the guide to add LTE support for other carriers? Is there a chance that it would just work?
Regarding the previous reply, I couldn't find a US Open ROM available for the 820UM models (only for QM), but you could try Canadian Open, for example. My point is to try and make it work with one of the ROMs as is, without messing with some extra steps that may or may not work.

Yeah, I guess i understood that as being able to add the functionality. But after more research, flashing a different rom is more likely to be the solution, which confuses me about adding profiles if it doesn't truly work?

So yeah, after more research, looks like flashing either the open market or the verizon specific variant would work. I did try it first without any modifications to the us cellular rom but still not everything worked. I have a Lg v30, but few things that are no longer ideal was the recent CDMA discontinuation from verizon at the start of this year, also had recently dropped it and the screen flashes bright white light in your eyes at random times... so lol, not ideal.
What Im probably going to be trying when I get the time is flashing the open market, and if that dosent work, it seems the verizon specific would.
Thanks both for the inputs!
