[Q] From which country is my LG G3 ? 10L-EUR-XX

i want to update my phone to lollipop but seems like i never get the update no the phone, i am trying to figure out from where is my phone ?
in the software version it says 10L-EUR-xx
on the phone box it says NEU
can u help me understand from where is my phone ?
when i enter my IMEI on a website i cannot post the link because i am a new member
it says Model:LGD855
Latest Firmware85510L_00
why cant i get lollipop legit? without bricking my phone......
thanks in advance
The software version "10L-EUR-XX" means you have the European variant of the LG G3 D855 which means you can flash a Lollipop kdz as long as it is matches your phone. And if not, you can wait until your carrier releases the updated lollipop version. This means you won't run the risk of bricking your device if you just wait.

H815T - reflashed via LGUP.. now showing as H815??

Hi guys,
I've recently had my Hong Kong H815T repaired and it's come back to me with v10B-OPT1-YT. The hardware info shows H815T.
I had updated via LG Bridge to v20C, after completion the software shows v20C-OPT1-YT, I was hoping it would show v20C-HKG-TT. The hardware info still shows H815T.
Getting further annoyed at this, I decided to use LG UP and 'refurbish' my phone back to V10B-HKG-TT.KDZ for the H815T using the methods provided on XDA. However in doing so, it has flashed back to LP v10B-OPT1-YT BUT now the hardware info shows LG-H815 WITHOUT the T! Does this mean I have disabled Band 40 due to the model number change? Have I just monumentally f**ked it up somehow?
To add more to the problem, LG Bridge still indicates my phone is ready for an update for H815T v20C (04.02.2016) but I had already updated to that version...
Anyone able to help? My OCD is going ballistic lol, I wouldn't have paid extra for the T model if I didn't intend on using B40!!
Is there any way I can get H815T back showing as the model number?
Or at the very least, does this affect the extra radio band available on the H815T (B40 2300mhz)
My baseband version is MPSS.BO.2.5.c3-00101-M8992FAAAANAZM-1.31581.1
Software version is v20C-OPT1-YT.
Prior to sending it in for repairs, I was running v10F-HKG-TT and my model info was correctly displaying H815T.
Christ I haven't had my phone for 7 weeks and I already messed it up eugh.
Any help would be greatly appreciated.
Cheers,

Unable To UNROOT LG G3 Korea, Help!

So I bought a rooted LG G3 Korean version (back then i didn't know it was rooted). MODEL d855.
So I looked it up how to unroot it and I found many solutions on how to unroot it, but most of them used LGFlashTool so i went with that method; had everything downloaded but i couldn't find any firmware documents for LG G3 Korean version, so i used different ones such as: European, Hong Kong and many others that i can't remember but all seem to fail to download, all of them stopped at 6% after my failure I decided not to unroot it. But whenever I turn my phone it goes to download mode/firmware update. I have tried holding multiple buttons and taking the battery in and out but nothing seems to work. So now i'm here with my new phone stuck in download mode.
Can anyone help me Unroot it or find a way to exit download mode? I just want my phone back cuz right now it was a waste of money.

what i know is that D855 is the international version, While korean version have a F400 model number with a suffix base on their service provider in Korea (e. F400L for LG U+)
it seems that you need to flash the correct firmware to recover your phone. (it's important to know what model number you have)

My knowledge on phones isn't that great but before i tried to unroot it i looked up how to find my model number and somewhere in the settings i found that it was the D855 and under my battery it says D855 and under that it says made in Korea.
So the Koreans have the F400 but i have the Korean D855, well now i'm totally confused

Can I update from kitkat directly to marshmallow? Plz help

Hello, I recently bought this phone G3 model D855 and would like to install the latest stock marshmallow version. Right now I have 4.4.2, so I am wondering if it is safe to flash marshmallow direct or do I need to update it to lollipop first. Also if you can direct me to the files I need and the procedure. Thanks
Some info about my device
Android 4.4.2
Kernel version 3.4.0
Buils number KVT49L
Software version D85510n
It is rooted
Also I checked the imei number on several sites, and it is showing Sprint as carrier, model LG LS990 suffix ASPRTN how is that possible if its model is D855, which is also printed back inside the cover. Also my imei ends with 855, so which firmware should I install for Sprint LS990 or D855 model?

Download LG PC Suite,install it.
Connect your phone to your PC and it will automatically detect and ask you to install the firmware update.

Hi all,
Sorry if this is a noob question but I am completely new to LG. I have a second hand LG G4 h815v10h on android 5.1, and I want to upgrade manually since the OTA doesn't find any update for me.
I installed LG UP but after installing the phone drivers and launching LG UP, it shows me "model unknown" and I can't run the software because "You have to select a known model, please"
Here are my phone specs :
Model number : LG-h815
Android version : 5.1
Baseband : MPSS.BO.2.5.c3.00100.M8992FAAAANAZM-1
Kernel : 3.10.49
Build number: LMY47D-XT
Sofware version : H81510h
Thank you so much for the help !

You could check out this link: http://storagecow.eu/index.php?dir=Xda/LG+G4/H815/Marshmallow+6.0/
However, as the phone is 2nd hand, the ONLY way to be sure what actual model you have bought, is to open up the phone and check the model # on the motherboard. There are guides with pictures on the web to show how to do this: https://www.ifixit.com/Teardown/LG+G4+Teardown/42705
You could end up bricking your phone flashing an incorrect kdz for your actual phone model, so better to be 100% sure, first.

Thanks for the answer.
After looking for the model number, I found out mine is F500L, even though I have h815 installed
Also, LG Bridge managed to find an update : F500l30B but fails to install the update everytime.
Aaaand another problem is even though I want to flash the phone with adb, I can't unlock the bootloader because the box "Allow OEM unlock" in development options doesn't want to activate itself. Grrrr...
Any other clue ?

You could try using LGUP-NEW (https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803) to flash using the upgrade mode but it might be better to use the refurbish mode with the same android version you are on now and if successful, then use the upgrade mode to install the newer android version.
However, it looks like whomever you bought the phone from might have converted to H815 following this guide:
Lg G4 F500L - Fixing and Converting to International H815 Model at https://forum.xda-developers.com/g4/general/lg-g4-f500l-restore-signal-flash-815-t3214574
I would type in "go back to F500L" in the search thread box there first, to see what other members have had the same issue and whether they were able to do it successfully etc.
