I've read this post like 100 times now, and i still don't know what to do.
http://storagecow.eu/index.php?dir=Xda%2FLG+G3%2FStock%2F
I know my model is D855, but there are a lot of versions with the same name, i'm not sure which one is the right for me.
I'm running 5.0 Lollipop on my G3 and wanting to downgrade back to Kitkat for root. (I don't even know why i updated to Lollipop in the first place).
Also i need to download the correct software version that i need to downgrade to (ie. KitKat), but i cannot tell the difference.
Any Help would be greatly appreciated, Thanks!

Do some research into the LG Flash Tool.
As long as the software is compatible with D855 you''re good! There can be different builds such as (last 3 digits) 10r or 10c, but they are essentially the same thing with just minor changes. If it's cleared for the D855 you'll be good.
There is setup that must be performed on the Flash Tool, so make sure you follow the steps in various guides attentively. I would tell you what you need to do, but I cannot remember every detail.
A lot of the guides for downgrading will be found in the same areas as guides for rooting because downgrading must be done in order for some root methods to work.

Any kitkat build for the D855 will suffice. I remember doing TOT, but I'm not familiar with Kdz so I cannot answer that.

Hi,
First time poster, long time trawler... thanks for all your info over the years.
I have a specific question about downgrading to KK from L on my branded Three Mobile UK.
I had rooted on KK and was loving it, everything was working great.
Three kept pushing the OTA at me, but because of root it wouldn't take.
Borrowed a PC (I run mac for work) to run LG Suite and (back up first) fix upgrade errors to unroot to take OTA.
For some reason it bricked it...it just sat on Firmware update at 0% forEVER. Wouldn't boot past it or recognise the device anymore.
Had to use the Mobile Support tool to bring it back to life... although this resulted in an upgrade to 5 anyway.
I'm really not a fan of L. Won't go into details as to why it sucks, but I want to go back to KK and root, and then wait for L to get root options.
I've never flashed a ROM before, however there's a ton of resources here so I will give it a go.
I want to go back to the exact same ROM that came with the device which I THINK I have tracked down to - D85510g_00 via
http://forum.xda-developers.com/showpost.php?p=53606494
and
http://www.mylgphones.com/lg-g3-firmware-checking-the-software-version-and-update-history
Can anyone confirm that would be the right one... Is there any reason why I shouldn't use this ROM?
I want to go with what works, and not risk bricking it by installing an unbranded ROM in case they've used some sort of security measure that I'm unaware of... or am I just being a noob?
TL : DR
ON Lpop, want KK back... downgrade to D85510g_00.kdz for 3 UK (Hutchinson) branded ROM - Correct?

Thanks for your reply. Will borrow a PC again and give it a whirl tonight.
I have the KDZ file, USB drivers and LG Flash tool already downloaded... and intend on following this guide - http://forum.xda-developers.com/showthread.php?t=2785089
I have seen in the second method mentioned in that guide - TOTs and DLLs, could you confirm that these are different paths to the same goal? Either I need KDZ or I need TOT & DLL... but I don't need KDZ and TOT and DLL? Have I understood that correctly?

yep that sounds about right
All good.
Back on KK and rooted again.
I wonder if someone nice can help me understand a little better re what version's of firmware I can install on my G4
My G4 is Model LG-H815 I noticed the box has TWN on it so it most likely came from Taiwan (I purchased it on ebay from Kogan) and I am in Australia on Telstra network.
Is mine classed as the international version then?
It came with V10b-TWN-XX installed on it.
After reading another thread I yesterday flashed it using version from Poland 10D H81510.kdz using the KDZ flash LG Flash Tool 2014 method
It is running fine on the above and doing that flash removed the Chinese keyboard and stuff so that was good.
I noticed after checking I am still vulnerable to the Stagefright issue so would like to find a newer rom that has this issue fixed if possible.
I am confused about all the versions of ROM's going around and was hoping someone could give me an overview of the various one and pros and cons against using them on my particular G4.
I dont mind doing a complete reinstall so keeping current data isn't important.
I would also like to root the rom (mainly so I can adjust the DPI) So some help on rooting the latest ROM would also be appreciated.
Thanks for your help.

I don't know for sure, but you could try cyanogenmod, it should have a working installerar that helps you (depends on if they made the installer for your devices)
Sent from my LG-D722 using XDA Free mobile app
If your model in the model report is H815, then you are safe to flash the unbranded European kdz. As I have said in other topics, as long as it's not H815T, or H815P or whatever, then it's fine to flash EU kdz on it.

Ok then that great - tks
So whats the latest version rom out at the moment I could use and how do I root after flashing it?
Many thanks for your help.
Frosty
The latest version that I know of is the European Open 10E.
After you flash that one using the kdz flashing method, you can check around for the rooted 10e img and flash it using low effort root method.

OK all done - all working fine..
One small issue one of the apps I use "Netatmo" will no longer install "This item is not compatible with your system" error when trying to install from the G4 or via GooglePlay on PC..
Must be some sort of region thing perhaps?
And I get "Warning current version is not avalible for user ....." error on boot up.
Any idea how to get around that?
Thanks again.
AFAIK no way to get rid of that, but it doesn't affect any usability of the phone, so I just learn to ignore it.

Yes there is a way to get rid of it, as long as you have root. I don't know the specifics but I read it in one of the threads. Just search the error I'm sure you'll find it.
Hi,
I purchased the phone in the UK from the network carrier Vodafone. I have done a fair bit of research on the rooting and unrooting process mainly via videos and reading tutorials on XDA.
I would like to root the phone and gain super user access and install some Xposed modules but would also like to be able to unroot and flash back to a stock Vodafone firmware encase I need to claim under warranty. I have been trolling the internet to get the correct KDZ file and found this site (ttp://devtester.ro/projects/lg-firmwares/country.php?country=United+Kingdom). I believe that the correct firmware may be on here but am a little confused on what the suffix and software version means to be honest.
The reason for my confusion is that I updated the firmware to 6.0 Marshmallow through the LG bridge but when I now check my phones software version it states v20b-234-15. I assume this is right but from memory the first software version when I got the phone was something like H81510B_00.
I cant remember exactly what it was before unfortunately but the KDZ files I have found state H81510C_00 (Suffix - AVDFVK) and H81510C_00 (AVDFLR) and this does seem to make sense but I'm thinking it was B instead of C but and not 100% on that.
Do you think these KDZ files would be the correct one to flash back to encase I run in to some problems rooting?
I am also assuming that this KDZ is Android Lollipop and not Marshmallow so is it OK to use this to revert back from Marshmallow?
Thanks and any help would be much appreciated.
Ross
The 10X version are all Lollipop, 20X is marshmallow.
When flashing a KDZ on your phone, what's important is what model your phone is. H815 in your case.
If you want to restore to stock in case something goes wrong, you can find everything here: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
In there is a link to this directory: http://storagecow.eu/index.php?dir=Xda/LG+G4/ where you find pretty much all KDZ files for G4 phones.
I'm not that experienced myself, but I rooted my phone just recently and I can share my experience with you.
I have a H815. It was a V10c-TWN-XX version (Taiwan). I updated to Marshmallow with LG Bridge also and the new software version was V20b-TWN-XX.
Marshmallow rooting is not possible on my phone because I can't unlock the bootloader on it. And Marshmallow rooting is only possible with an unlocked bootloader. Unlocking the bootloader is only possible on European phones (http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS). I asked autoprime (renown user and developer here) if I can unlock bootloader after flashing an European KDZ on it. He said no, having European software on it is not enough, it has to be a phone manufactured for the european market. Dont know why, guess because of different hardware.
So, not being able to root MM, I had to revert back to stock (downgrade) using one of the KDZs.
I chose the most recent one in the directory I linked (which is the Poland H81510E). In the "Go Back to Stock" thread I linked the OP says to use LG Flash Tool 2014, which unfortunately doesn't work with Marshmallow. But fret not, it works with LG UP! http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
When I tried flashing the KDZ with Flash Tool 2014, the process failed with an error at 5%. It worked flawlessly with LG UP. Here's more information regarding downgrading, but it really isnt hard. Just download + install LG UP. Launch it. Connect your phone. Choose KDZ file. Select option "upgrade". Hit start.
NOTE: after the firmware update was done, the phone rebooted automatically and for me it stuck at at the LG Logo (bootloop). But a simple hard factory reset did it, the phone booted and my new version was 10e-something. With Lollipop 5.1 of course.
After that, I rooted my phone using this pre-rooted image: http://forum.xda-developers.com/g4/development/h815-eu-l-p-t-sea-twn-t3176195
and this guide: http://forum.xda-developers.com/g4/...-tmo-vzw-intl-variants-soon-root-lg-t3164765/
I now have a "H81510e-EUR-XX" Lollipop 5.1 with root (SuperSU 2.49).
I don't really know about Vodafone and if carrier specific firmware is necessary in this case. If not, you could use any 815 firmware.
From the site you have linked with the KDZ files..... it seems they are all the same.
If you check the table for H815 KDZs from Vodafone, there are some 10C and 10D versions. Now I compared the fileKey parameter in the URL to the 10C files and the 10D files and also the bytes of the files.
All the 10C version are identical to each other, same for 10D.
Check out this screenshot I made for you: http://i.imgur.com/Ie0w4us.png
Bytes are also identical, so it's pretty safe to say those are the same files.
Dont know why they are listed several times there. The suffix doesnt matter.
I'd grab a 10D if I were you. But I think the Poland 10E should work, too. Better confirm it with somebody else though.
If you flash your system to 10e, you can use the pre-rooted image I used. Otherwise you will have to inject root yourself: http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586. In this method you create an image of your system and inject root into the image, which you then flash back on your phone.
Hi.
I purchased a second hand LG G3 quite a few months back, only to find out after trying to update that my version was the D858HK, which does not seem to have any official way to update past KitKat on the phone. After some digging around, I did find some methods, like flashing the KDz file. However, none of the KDz files I've found on the internet seem to match the model of my phone, which is D858HK10d, or v10d.
I was wondering if there is any other way to get rid of KitKat and move on to the newer versions.
It is rooted.
Thanks in advance, XDA Forums. You guy's do the Android God's work.

LG PC Suite doesn't recognize the phone. And the kdz files there dont include the model of my phone, which is a D858HK10d.
Where are you getting the model #? The 10d part may refer to the ROM as 20x would be LP, and 30x would be MM.

10d is the Software Version of Android KitKat..
Your device is D858HK.
So you can proceed installing that kdz file.
I'm trying to downgrade my G4 from marshmallow back to lollipop. My anti-rollback # is 2, and according to this as long as the anti-rollback # is the same on both the installed version and the kdz, flashing the downgrade doesn't hard brick the device.
So far I've been unable to either find one, or clarify if one exists for my variant or not. Can anyone help? Thanks.
In any event ...

In any event ... if you do happen to find an LP stock image to try, make sure you use LGUP-NEW (https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803) to downgrade to the stock Lollipop image as it should throw throw up an error regarding the anti-rollback version roll back and not proceed with the rollback, thereby avoiding any brick worries for you ...
You may have to do a bit of trial and error but it would help if you post your exact software version that you are on now for anyone to assist you in at least pointing you in the right direction for LP kdz's to try.

Oh, so LGUP-NEW pretty much let's you throw any kdz at the device and if it would have normally bricked the device, instead it comes up with an error? That's pretty neat.
My specific software version US99125a, and if it helps at all, my end goal is to hopefully root my device.
Well, not any old kdz ...
