3G is not working on LG G3 D855 - G3 Q&A, Help & Troubleshooting

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

[Q] Help with F180L on US T-Mobile

Hi,
I've got a brand new F180L phone with baseband version APQ8064/MDM9x15M and software F180L20s.
After searching forums I still cannot make heads or tails of this phone...
My questions are:
Can this phone be flashed to work on US T-Mobile network?
If yes, what is the maximum data rate possible?
Is there a good tutorial on how to do it? It appears this phone can be hard bricked by flashing wrong radio so I would like to avoid such mistakes.
I live in the "upgraded" area with 1900MHz frequency re-purposed.
Thanks in advance!

Hi there,
I am having the F180L and have flashed the E975 european version on it. It is working as good as stock, no issues so far in India with 3G, HSPDA or 2G (we dont have 4G yet). And ofcourse, all korean crap gone
The process is failrly simple, you just need to read through the forums, there is everything written here.
From here you can find the ROM's just pick one near to you; may be Europen E975 http://forum.xda-developers.com/showthread.php?t=2093382
Then use kdz to flash it on to your phone. No need to root your phone or else. Use google to find how to.
Root your phone
Then flash baseband of F180L;

As I see, problem still is there. If your F180L worked before, works after.

It's a great, smooth ROM and the battery life is better than stock on the V5 as well.

[Q] Easiest way to convert F180K to English version

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
Kernel Version 3.4.0
Build Number KOT49I.F180K30c

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

[Q] No sim detected

Hay guys i just recently flashed my g2 ls980 with stock zve firmware. Everything us working fine except that sim is not being detected no matter what i try. I am really confused as i am a total newbie and am unable to understand technical stuff.
With stock ZVE (that's pure Sprint stock) which SIM are you referring to because with that stock ROM on the Sprint G2 the only SIM card that will ever be recognized at all will be one from Sprint to enable LTE network support.
So... I don't like to assume things, hence the question: what SIM card are you talking about?
The LS980, aka the Sprint G2 variant and the same phone I have, is network locked aka SIM locked to Sprint only if you're running a pure stock ROM which is exactly what ZVE is. The only ways to get the SIM unlocked for other network operation would be a) do a somewhat complicated set of tasks to get it to work (not worth the hassles really and certainly beyond your admitted "newbie" status with respect to this level of tech) or b) install a custom ROM like CloudyG2 (the name just changed today, prior it was known as CloudyG3 but that confused people with the LG G3 and they were trashing their phones trying to install it - it's a G2 ROM ported from the actual G3).
There are other ROMs as well that unlock the LS980 for GSM operation aka regular SIM cards, you may end up using one of them to get proper GSM functionality - LTE support is spotty depending on the networks in your area and the Sprint G2 only supports a few LTE network bands.
Thank you very much for your reply @br0adband. I was able to use my GSM (telenor) sim again but i encountered some problems. Here is the link to my post:

LG G3 D855[v20g-SEA-XX]: 4G available on Menu but not connecting

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.
