[Q] Downgrade LG G3 - G3 Q&A, Help & Troubleshooting

Hi everyone,
First of all, I'm a new member to XDA and English is not my native language but i think it is save to say that I am an advanced Android user and that I control my English quite well.
Now this is my problem:
I upgraded my LG G3 to Android 5.0, but I want to downgrade again because i want to root my device first and install TWRP recovery.
As far as i know there is no other way of rooting Android 5.0 than already having custom recovery, but correct me if im wrong.
I have been searching for a way to downgrade but without success.
So here comes my question: How do i downgrade my LG G3 D855 (European) from 5.0 to 4.4.2?
If there is someone that can make me a tutorial on rooting Android 5.0, please do.

I would like to know the same.

first , read this list : http://www.mylgphones.com/lg-g3-firmware-checking-the-software-version-and-update-history
then go here: http://forum.xda-developers.com/showthread.php?t=2791761 and choose the kdz file for your phone,
here : how to use the LG flash tool 2014 http://forum.xda-developers.com/showthread.php?t=2785089
take into consideration that the suffix " A6 " is for 16 gigas phones.

Alright thx man, I'll be trying it soon!
Samsung Galaxy S plus ? (First Android phone!)
iPhone 4 ? (Biggest wast of money ever...)
Nexus 5 ❤ (Still in love!!)
LG G3 ? (It is a beast, but a lovely one!)

I downloaded the european 10A one but after installing it, my g3 went in a bootloop. I cant download the Dutch ones because those are 20e which is Android 5.0
Which one should i download?
I'm from the Netherlands by the way and i bought my phone at Vodafone (might be some usefull info)

can you access to recovery or download mode now?

Well, I flashed 20a again, which is android 5.0
I think I have to use the other flash methode that resets my phone to downgrade but I don't have the time on my hands to go through backing everything up and setup my phone again.

so you didnt click on CSE Flash on the LG Flash tool. I'm still dealing with lollipop 20f, battery drains a lot.

Nope, I used normal flash which put my g3 in a bootloop. But apparently I have to use the other option when downgrading.

likely because you are going back to dalvik without clearing the cache.

Yeah probably, but I don't have a lot of time on my hands right now. I'll try this again in a week or so because when it doesn't work I won't have a stable phone anymore

Bhai jaan Main bhi Pakistan se hi hun ... you need to root your phone and install a custom recovery CWM is my suggestions although TWRP works fine.... you can install Sling 2.2 here http://forum.xda-developers.com/showthread.php?t=2786769 it will take 3 hour if you have one MB ptcl connection if faster connection it will download early and it totally supports Urdu and have many neat features I HOPE IT HELPS
I am also from Pakistan.. 1st make sure that u actually have a E975 model...
Check at the back side of phone underneath the battery, 2nd take a backup of our efs..
A free tool FreeGee from play store can take backup and install cwm recovery... U need to be rooted though already... Sling 2.2.2 is better...

[Q] New delivery, LG-D855V?

Hi all,
I just receieved my new LG G3 from Vodafone Australia. It's currently charging but upon inspection it has a model number which I hadn't noticed when I was researching the phone (LG-D855V).
I've attached pictures of the box, manual screens from the phone referencing the model number. Does anybody know what the difference is etc?
I'd say the V is just for Vodafone. You should DEFINITELY get to flashing a newer rom or doing an OTA update asap. That's the base rom for the phone, v10a. The latest 4.4.2 version is V10L I think. Alternatively, you can go to Android L. There's a dedicated LG G3 Australian Owners thread in the general section if you need help from any of us

Ah makes sense I guess. I've checked the hardware and it all seems identical to the D855. I came from a Nexus 5 with L and I'm already missing it so I'll definitely be looking to get an L rom on there.
Will take a look at the thread and do some reading. Thanks for your input.
did you get a gift?
optus is just d855; free wireless charger
telstra is d855k; free g watch
to clear confusion - you can flash d855 roms, the letter v doesnt matter. it confused me when i got mine lol.

[Q] Where is my G3 really from ?

Hello all, I have a question. I would like your opinion. I want to return my G3 to LG Official stock with OTA working etc, just like it was when I first bought it. So I'm looking to flash the proper and right kdz, but I came across a "problem" .
I have the International 16GB D855. The sticker on the box says that it's " 6SW(Switzerland) " , but when I'm searching on http://lg-phone-firmware.com/index.php the firmware based on my IMEI, it says that the firmware is 6ES ( Spain ).
So what firmware am I supposed to really flash? Is the IMEI one the right one since it searches the phone on LG's Servers?
But then again , the 6SW version hasn't gotten Lollipop update yet, the latest 6SW firmware is version V10L, while my G3 got the Lollipop OTA version V20F before I downgraded it, root and flashed it custom Firmware.
What is your opinion? Sorry for the long post and thank you very much.

You can flash any compatible EURO rom on to your device, like the latest German D855 rom ending with 20H. Link https://mega.co.nz/#!AMoUjCQY!llgH-KlTB4J0paynnnGpIq0ANCAEtXjmUvpx8G8ApQM and flash with LG Flash Tool.
BTW: did you backup your EFS folder?

when i open lg mobile support tool it says there is software upgrade do u want to upgrade?
OTA's can take longer to be available than the kdz (via PC Suite). upgrade if you want to. I'm not sure of the changelogs, but it'll be the typical bug fixes etc. if you're having issues where you are, perhaps it might be in your interest to upgrade

Changelog
Update #1 (20.06.2015 @ 3:05 CEST)
Started thread
Added v10c_00 based firmwares on list
Added other kdz files from General thread
I would like to ask:
If anyone has done the update via OTA it would be nice to see the changelog and know what's new and if an update is worth the time.
Changelog
Update #2 (20.6.2015. @ 21:34 CEST)
Added v10f_00 Indian kdz for H422 variant of device
_______________________________________________________________________________________________
@polfrank yeah it would be nice to see what are changes, but unfortienatly I can't see that because I'm pulling kdz files from few trusted sources which don't say what is new
Are these kdz files derived from the LG site using IMEI codes?
Changelog
Update #3 (25.6.2015. @ 22:03 CEST)
Added support for H440Y ROMs
Renamed thread to add support for H440Y phone
Added v10d_00 Taiwanese ROM to list at H440Y variant of phone
_________________________________________________________________________________________________________________
@ShinOrochiX seems that all kdz files are collected via IMEI code from LG site and all should work great no matter of your IMEI
Also if somebody find newer variant of ROM for any of named devices in first post and in thread name contact me via PM or post link here in thread so I can edit #1 post
Changelog
Update #4 (27.06.2015 @ 14:03 CEST)
Added v10f German firmware for H440N
Added v10f from unknown country ( Credits: @deni-brasco for submitting it in General thread, but next time please write from which country it is)
This is H440n Portugal/Switzerland edition:
http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW4BKUG13267AM42E0811ZR/H440n10f_00.kdz
The one provided by deni-brasco is H440n Italy edition.
Changelog
Update #5 (27.06.2015 @ 17:18 CEST)
Added v10f firmware from Portugal and Switzerland (same kdz), thanks @polfrank for giving it
Updated v10f from Unknown country to Italy, same thing go to polfrank and again thanks deni-brasco for submmiting it.
Testing v10f Italy right now. Everything works as expected, root, xposed etc.
It says v10c at the settings.

Upgrade or clean install? I mean CSF Flash or Normal Flash via LG Flash Tool? I ask that because I want to do Normal flash without wiping anything (it is annoying to set up 5 different e-mail addresses for 5 different things like college, private, hangouts, youtube etc)

Normal flash. It keeps all your data with no problem. You just have to reroot and set xposed again.
LG Spirit H440N Stock rom
Hello everyone.
I have a sim free LG Spirit H440N handset. I got it free of charge from 3UK, who sell all their phones unlocked. Unfortunately, it has a 3 splashscreen on boot, and other 3 stuff built in. Is there a stock rom available, that has none of the 3 bloatware in it? If so, where is it, and how do I flash it? I would rather not root the phone if I can help it; although I will do so if it is necessary. Is there a method to return it back to the 3 version, if necessary? I have rooted phones before, and installed custom roms, etc; but not for a while. I thank you in advance for any help you may be able to offer me.

Hi,
I also have the Three customised firmware-I don't like it either. There is a way to download the firmware, check here. As for firmware without Three's crap in it we'll have to wait for a non-network UK retailer to list it, then if we can get an IMEI, be it from a store display unit, we can download and flash that firmware (when it becomes available). But I don't know if anyone other than Three will sell it, Three has had it for about 2 months even though it was exclusive to them only for 1 month.

Thanks ShinOrochix. So nothing to do but wait then. There's no need for the stuff that 3 put in the phone firmware. It doesn't have a huge memory to start with, and these extra files are just an unnecessary inconvenience.

Yeah, useless bloatware. I just got rid of some of it but am stuck with the bootscreen, rather not root the device yet. As for memory, your right, with all my stuff installed I got just under 2GB free, had about 4GB on my previous Xperia-but who's to complain, the Spirit is a great phone.
I'm in the same boat as you. I debloated as much as I could, but I can't get rid of the bootscreen. The 3 logo sits there for ages. I downloaded a couple of boot animation changer apps, but they didn't work. Perhaps the apps were set to look in the wrong location for the stock boot animation. More investigation needed into the phone's file structure, I reckon.
Hi, I'm Italian and I bought this phone today. On "ABOUT PHONE" I can read version "V10C" but I don't know if is really V10c, or v10f. I want only a stock italian firmware NO BRAND!!! I hate all that apps by TIM!!!
Which firmware do you suggest me???
Hi guys, I have found this site......can be useful???
http://lg-phone-firmware.com/index.php?id_mod=168
Hello. In this site it is being claimed that there is a v10d version of the firmware for LG H440N. (I know the picture of the phone is wrong, but it seems they got it right on which smartphone they're talking about...)
http://www.hanfei.name/kdz-download...-v10b-v10c-v10d-v10e-v10f-stock-firmware.html
In gaodi.net there has been a V10d version a while ago but it was only in some weird versions like Spain Orange, Portugal Orange, Poland Optimus (see here) so I haven't tried it. Has anyone tried it? Is it really v10d or is it like the others, where v10e=v10b and v10f=v10c ?? So maybe v10d is actually v10a??
