Hi guys, I need some help.
Two weeks ago my mic stopped working so I installed the latest stock rom for my G3 D855 (D855P20C_00.kdz) with the KDZ method so I could use the warranty. (I followed this procedure http://forum.xda-developers.com/showthread.php?t=2785089 and downloaded it here http://lg-firmware-rom.com/ )
Somehow LG find out that I had root before, they show me their software and it was displaying "rooting".
I don't know how, because it was totally formatted, I followed the procedure, I had lost twrp, root and it was in the same version I had when I bought my G3 which was 20C.
I was lucky, they had a lot of warnings in the room saying that 27/01/2016 was the last day that they would accept the warranty for cell phones with root, but they accepted mine.
Today I received my G3 back and they changed the main board, now I am afraid that if I root it again I won't be able to use my warranty without sue them first, which takes a lot of time.
I'm from Brazil, I read that in some countries in Europe they already separated the hardware warranty from software warranty, but here it's all the same, only one kind of warranty.
I am really suspicious that the technical assistance could have installed a faulty or old main board hoping that I would root my device again and then I would have to pay for the assistance in a next time.
Btw the new board also has the 20C rom..
I really want to install stock marshmallow again or fulmics rom, if anyone could help it would be really appreciated.
Sorry for my english and thank you in advance

Last week, LG G3 notified me of software upgrade, I was running 10i at that time. So I went ahead and upgraded. I was expecting to get 10L but somehow it upgraded from 10i to 10J. So now I am running V10J-SEA-XX. I am not able to get OTA update as it shows that I am running the latest version which is not true. It shows last update on 24th Oct 2014. I am in India, phone was purchased from Dubai.
In hope to get 10L, I installed the LG Mobile Software Tool and to my pleasant surprise, it showed me an upgrade. I started the upgrade process, it download 1136.13MBytes of upgrade and started upgrading my phone. It failed in first attempt and it prompted me to remove battery, restart and press retry button which I did.
On Second attempt, everything went smooth, phone was rebooted in the firmware download mode, I could see 0-100% progress and the entire upgrade completed as expected.
However, when phone was restarted, I see that I am still on the same software, V10J-SEA-XX. It even shows last update on 24th Oct 2014 ( OTA date). I restarted LG Mobile Software Tool and it again shown the update available. When I choose to upgarde, it again downloaded the same 1136.13MBytes file. This time upgrade process completed in first time itself. Unfortunately, I am still on the same version.
Any help will be appreciated.

Well, I saw a few threads, not sure the one you suggested but that solution is possibly applicable if the device was not recognized. Here I could see the progress on both LG tool and mobile so both are communicating fine. Pls correct me if I am wrong.
Anyway, changed the port to COM41 and trying again.
Update: Repeated the entire procedure with COM41. This solution doesn't work. I am still on the same V10J-SEA-XX.
.
Bump...can anyone help?
Thanks
Same Problem
Hi there sorry I can't help but I have the same problem.
Live in the UK but purchased an SEA version. Didn't realise it would cause me such an issue.
Unfortunately, I don't want to root my phone as it will possibly disable my Barclays Bank Mobile Banking app which is pretty useful to me.
My only hope is that LG will upgrade the SEA version to L when it does all the other regions as well.

I am fine with rooting if that solves an issue. Any lead?
I just received an OTA update but it only updated to v10K, strangely no v10L yet.
contacted lg
Someone asked lg uae this question and what they have said is that the v10j or which ever one youve got for the region of ur phone is the same as the other regions' v10L or v10n and it isnt more advanced than ur version of v10...
(I cant post links because i am a new user)
Evidence is on the LG UAE twitter @lggulf approx 25 postd down
I live in uae and my g3 updated to 10k today
Hello XDA,
I got an LG G4 gifted, and as one of the first things I want to do is to root it. However I seem to have quite some difficulties with it.
My previous phone was a Nexus 4, and I simply rooted with 'Nexus Root Toolkit'.
For this phone there appears to be many, different ways to do that.
First thing I need to be sure is what exact model my G4 is.
In 'Phone Info > Hardware' it simply says H815. In the LG Mobile Support Tool it says H815B (Which gives no result on Google). The phone is from Germany if it helps.
Second thing is that it says I can update to SW version v10c. But when I download the update, it simply throws a 'Invalid Software Package' error at the end of it. The LG Mobile Support Tool says I have no update avalaible instead.
Third thing is that I don't remember if I have to unlock the bootloader to root my phone (did that only once on my N4, forgot if it's needed). If yes, can somebody link me to the appropriate page? (I've read around LG itself released a tool to unlock that?) (Also, I will loose all my data IIRC?)
Last thing, obviously, the most appropriate Root guide for my model. I've read many of them, one requires you to have linux on your PC (Which is a nope), others mentions '10c' (which I suppose is the update I'm unable to get). So far I got myself only very confused. (Root voids warranty? IIRC LG still covers phone with root?)
Thanks in advanced for your help
EDIT: Currently trying with LG Bridge software, seems to work and says my phone is H81520A (So I suppose the part after the device code is the 'SW Version' ?).
EDIT2: Apparently updating with that software worked. Now on v10c (Marshmallow 6.0 - Unless there are other updates waiting)
You can indentify your model by adding your IMEI to the following link: csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=
(look for the field buyer)
The unlock process is described in this thread.
But don't fash SuperSu If you are on Android 6.0, because it will fail to boot. First flash an custom kernel (like this) and then SuperSu.
If you're unable to unlock the bootloader, then there is no possibilty to get root on Android 6.0.
Thanks. It says DEU at the buyer line.
D(eutschland)EU(Europe) I suppose.
And thanks for the link. In the kernel page it says 'download 20a or 20b? What's that number? So I need a Kernel that inclused SuperSU as flashing it on its own will cause that problem in few words?
What about this? http://forum.xda-developers.com/g4/development/repack-kernel-root-android-6-0-t3232387
From what it seems, it's a custom kernel + root. Would I still need to unlock the bootloader? Perhaps using the 'LG Site' section from the thread you linked (http://forum.xda-developers.com/g4/general/unlock-bootloader-install-twrp-root-t3128241)?
The software versions are quite strange on lg phones. 20A was the first test version that was released in poland. The official version now is 20B but phones with a branding have different versions. For example my phone has a vodafone branding and has the version 20A, but it is the same as unbranded 20B. (so it's really strange some times)
Look what is written in the settings under software information.
You need to unlock your bootloader to root your phone on Android 6.0 (this will void your warranty). You're right, it seems that SuperSu is already integrated in the kernel so you don't have flash SuperSu separately. But i am not complete sure because i didn't unlock my bootloader.
Thanks a lot for your help.
I managed to unlock the bootloader, but then I fuffed up..
Accidentally installed SuperSU (Was following that guide, and forgot about what you said).
Now the phone is kinda stuck at the very start, with the LG Logo (Not the animated one, the very first one)...
I'm hopeless now? D:
EDIT
I'm trying to recover with this video (LG G4 KDZ Firmware Restore Unbrick and unroot tutorial -- can't post links yet..)
But the LGFlashTool throws an error at 9% (imgur link -- can't post them fully yet) imgurDOTcom/pR1NYHD
EDIT2
Apparently I'm trying to flash a KDZ with Android 5.x while I'm on 6.0, which is a no. Will try with a 6.0 KDZ if I find one...
Else I hope for LG assistance (Or Amazon support, since the phone is less than 1 week old)
EDIT3
No luck with KDZ, but now the phone is going past to the animated logo, but being stuck there..
EDIT4
This saved me: http://forum.xda-developers.com/showpost.php?p=63843511&postcount=146
Worked perfectly, my phone is back and fully working
Sorry, i wasn't online the last couple of hours, but i'm glad that all worked out for you

No problem, you were of great help.
I'm currently not trying to root until there is a safe procedure to do so for 6.0
I don't think that there will be an easier option in the near future. You can make a backup with twrp and try to flash the kernel again.
Mmm, currently I have only the bootloader unlocked. No root, no custom recovery.
I don't feel like to play more with these stuff in the near future, after I nearly bricked the G4
Perhaps later on.
I bought my LG G3 D851 brand new. As soon as I charged it and powered up I got a notice for a system upgrade. Naturally I did it. So it made Lollipop 5.0.1 on my phone. My next step was to root it. Well that's when the hell started. There several guides and tutorials. None are working. I'm with Wind Mobile in Canada ?. Not that that should matter should it? My question is will I be able revert my firmware back to the original and root it easily.? I was told that trying to root with ? is not likely going to work. How can I put my phone back to the "out of the box" state so I can root it?
Any help would be highly appreciated.
Hey, i own an israeli H815L G4. Im currently running MM 6.0 , and i want to root my phone so in order to do that I need to downgrade my phone to LP . I have someone who uploaded his v10K rooted img, so all I need is a v10k stock of H815L and I cant find it anywhere. Also, I managed to find some v10H downloads, but none worked. looks like I came late to the party. Another question : If ill install the rooted img v10k I mentioned on my 6.0 MM , what will happen? will it work?
Please help, thanks.
You're In Luck
Hi there, I also own an Israeli LG G4 (H815L) and somehow I still have a H815L v10f kdz (5.1)
I am just notifying you that i am uploading it to a website and I'll PM you the link later
Lucky you, not afraid of loosing your warranty/ don't have a warranty.
TBH, if I knew there was no such defect as "The bootloop problem" i would of rooted my phone too.
you can't know with LG, i heard even a few G5 users got the defect :/
EDIT: You will have to OTA till you reach V10K tho, also, I downgraded once because of battery life issues, and this kdz worked for me.
Uploading right now
Wow! Thank you very much!
Just so you know, my phone died before and the motherboard already replaced once, to a 6xx serial num .. Im not sure the problem wont come back tho, but if it would, Im pretty sure that LG wouldnt even notice that my phone is rooted, since it wont even start-up.. so I'm taking my chances.
A question about needing to OTA to v10k, is it possible? I mean, wont it just "jump" to the most validated version there is ? (using LG Bridge)
Thanks again man .

Do the OTA through the actual phone, not LG Bridge.
You are correct, LG Bridge would jump you to the most validated version of this country (In Israel it would be V20D, but using kdz you can push officialy to UK V20H or Poland V20I)
But, in OTA, on the actual phone, it will jump you from version to version.
So, from V10F to V10G (you get the point).
Also my internet died on me a few mins ago so i have to restart the upload, so it should be done in an hour approximately. happy to help by the way
Edit: Hopefully i don't fall asleep by then lel. its 1:35 am here XD (Israel time zone is ****ed next to other countries, if you live here, then you probably know that already.)
Hello.
i have an LG G4 H815, and it have a defected motherboard, so i made a purchase for a motherboard, and install it, everything work fine, but i notice that my number keys have hebrew alphabet. and i find out that the motherboard was H815L, i was like ok at least the phone is working, but what made me angry is that when i try to do an android update it always tell me "your phone is not registered yet"
i'm on android 5.1 and i need to know how i can install custom rom or at least the last android for the phone.
any help on rooting or installing any rom is very appreciated.
thanks in advance.
