LG G3 (d851 T-Mobile) Downgrading/Rooting/TWRP Guide - T-Mobile LG G3

I’m writing this because I had to go to so many different threads to finally get what I needed to get this phone running LineageOS. Credit to all who posted those guides & tools, this is just a cheat sheet for those having difficulties if you are running 30e firmware or above.
I’ve hosted all the links on my own server for convenience.
1) Download LG Flash Tool
2) Download D85130d_00_0404.kdz
3) Enable USB Debugging & Power down your phone
4) Hold Volume Up while plugging in your USB cable (you should now be in download mode)
5) Open LG Flash Tool & choose the following: (Using D85130d_00_0404.kdz)
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
6) After the phone reboots, re-enable unknown sources
7) Install KingRoot (I like to Disable & Force Stop the Lookout App. before doing this step).
8) Install TWRP Manager & BusyBox (from play store) – Note – I had to use BusyBox Pro & Smart install, as the free version kept crashing, your luck might differ.
9) Install TWRP from the TWRP Manager...
All Done, from TWRP, always make a backup first thing, wipe and your good to go.
(On the d851, to boot into TWRP from a powered off phone, you hold volume down + power until the LG logo appears, then release the buttons and re-press both of them down until TWRP loads up)
One thing you should always do on the Stock ROM, before installing a Custom ROM, is turn on "Device Only" GPS and get a fix in Google Maps (as sometimes it won't ever work until you do this in Stock).
If you are installing Lineage, here are some additional Links:
LineageOS (d851)
Root Add-on for Lineage
OpenGapps (ARM, 7.1, Nano)
** If for some reason any of the links are broken above, all of the files are on my ownCloud here:

Heres my speedtest (running mullvad vpn on an r7000 router running tomato) not bad at all

Anyone please suggest stock based MM rom for d851 stable,debloated​,rooted. Thanks

I am also finding this Solution.

What Android version 4.4 or 5.0 or 6.0 is the Kd file that flash with LG flash tool?
Is the Kdz file size correct 3.4Mb only? thank you for the guide.
I bought two of the G3 D851 one come with Kitkat 4.4.2 (I got updated to 5.0) and other one come with Marshallow 6.0 rom. I haven't root or anything except got the official update on the one that come with Kitkat 4.4.2 so i updated it.
Is there a good stock rom for this device? anyone have any suggestion which rom we can flash?

I found LG Flash Tool 2014 is not working any more for flash KDZ file go back to stock or downgrade/upgrade. LGUP is working better for go back to stock flash KDZ file. I bought G3 it came with Marshallow I looked everywhere but did not find any method working except use LGUP tool to downgrade or upgrade:
Download from this Vietnamese tread, it's working I flashed KDZ to downgraded from MM to Kitkat (D85010C firmware). It should work with other firmware LP 5.0 or MM 6.0.
http://lgviet.com/forum/threads/tut-nang-cap-ha-cap-rom-stock-bang-lgup.52437/
For install the tool you just need to run the two Msi files, comport should be under port 41 under device manager I think. LG Mobile driver (LGMobileDriver_WHQL_Ver_4.2.0_001.exe ) should also install before LGUP tool.
Simple instruction include in readme text file with the LGUP zip file. For KDZ fine when first open LGUP you might not able to browse for it, close LGUP and copy/move KDZ file you want to flash to the same directory as LGUP tool (C:\Program Files (x86)\LG Electronics\LGUP\model\8974). Open LGUP again it should show KDZ file, for downgrade just choose refurbish it should work it take 2-3 minutes to flash it. Once the phone reset and start setup you can unplug the phone from the computer.

D85130g
Can somebody confirm this works coming from the latest D85130g firmware?

G3 Downgrade Information
Is the following statement True or False:
Because I am currently running LG G3 software version D85130g, I cannot flash my phone with a custom ROM from the likes of LineageOS, Resurrection, Liquid or XenonHD without downgrading first?

30G can be downgraded using this guide

I have tried all drivers available, all ports on my my, and half of the com ports. Seriously LG Flash Tool and LGUP are a joke. This 30d kdz also doesn't work on LGUP.

Re: [GUIDE] SU640 Rooting and CWM Recovery
I don't know if there's one, have you tried searching on other sites? I think there's a method where you will have to flash baseband.img in order to install roms for p93x. I didn't try, I'm happy with miui. and I'm not sure about the method.
well thanks! i will search that. thanks for help

Ate you sure that the rom you installed is for su640?. Installing ROMs for p93x is incompatible with our device. Make sure that the developer of the rom states that its compatible for su640.

Thanks for the guide but i have a problem.
I cant install CWM recovery. Tried it two times but to no avail. The tutorial states that CWm is installed adn then it doesnt boot into CWM.
The device rooted succesfully though.
Any solution?
Vol down + power button doesnt take you to recovery? Have you tried rebooter?
In case cwm is not installed try it once again. If it has the same result try the OLD METHOD.

it simply means that your mobile is not rooted properly.thats why mobile not rebooting to cwm.
kindly root the mobile properly.if it again gives error , tell me
Attach a picture of the rooting guide after that it takes five minutes until the tutorial states that it is booting into CWM which it doesnt. I tried using rebooter to boot into CWM but using that i stumble upon a dead android with a exclamation mark over its stomach after the phone shuts down and tries to reboot into CWM.
Any solution?. And i updated my phone thorough LG software for the jellybean update.
Hi Guys, I'm currently on Custom PACROM and I'd like to try this Rom. Do I need to Flash this through LG Flash software? or I can just flash this through recovery?

CM12.1 is here for the LS980, aka the Sprint LG G2.
This is a source build rom, which includes all the latest changes from cm. The nightlies are starting August 2nd.
Instructions
Official support is now limited to ZVE and ZVG basebands. CM-12.1 is based on a completely new kernel. This has enabled support for the latest basebands newer than ZV8.
While many people and devices are in various states we officially recommend flashing back to stock then fully updating your device before using cm-12.1.
If you are coming straight from cm-12.0 the rom will not boot.
Download cm-12.1, and gapps. Put them on your sdcard, reboot to recovery. Flash, and enjoy!
The latest will be available at:
http://get.cm/?device=ls980
Gapps:
Official CM ones (soon):

sweet, been waiting for this! but-- latest nightly is from 7/26, and is only version 12, not 12.1, and no google apps? seems a bit preemptive to me
Downloaded and installed nightly from 08-04. Flashed over stock rooted ZVG then a full wipe.
good:
GPS seems to be much more responsive with cm12.1.
bad:
camera app wont open, downloaded google camera and others from the play store, nothing works.
no flashlight shortcut in quick settings panel, when i try to turn on via "OK google" causes force close. this is a really useful tool for me and its bumming me out its not included here, or in stock ZVG
Shiny, may be able to abandon the official firmware (again) a bit later when things are a bit more stable.
Anyone have any reports on if the screen double tap to wake works?
Can't wait to flash this. Been having issues updating past 5/17 on CM12.
After fighting with ZVG to get root it's all working. 7-17 Gapps was giving me issues though. Downgraded to 4-21.

Double tap didn't work on older versions, but you can tap 5 times to wake in the version I'm using (I don't know why it's 5... but that has worked reliably for me)
Hi everyone, Just when i think i am starting to understand this stuff i become a newbie again. I am running cm12 on my rooted LS980 with recovery installed and no sim at the moment want to update to CM 12.1 but what i understand is I just cant flash it like other nightlys. Is that true and if then what do i do to get 12.1 flashed on my device. I have tried to flash it like any other one but i get a big fail. Thanks for the help !!!

If you tot to any version of kit kat the phone will update to lollipop. Paste this address into your browser for root tool. http://sourceforge.net/projects/avicohh/files/Android/LG_One_Click_Root_by_avicohh.exe/download. Sorry, don't know how to put link in post as of yet. Autorec file is specific to sprint. File name is something like omg so good version. Autorec will take care of everything else for you. Then just flash 12.1 and gapps normally.
What gapps version are you guys using with 12.1? Initially I flashed 7-17 but ran into issues with the Play Store being unable to download/install any apps. I flashed 4-21 and now I get occasional, seemingly random vibrations, sometimes up to 30 seconds long. Doesn't seem to interfere with operation though.

[STOCK] H815 20B Images + KDZ + Flashables (system+boot+modem+bootloader)

{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

}
These are for the H815 variant only. Files are from software version 20B (Android 6.0 Marshmallow).
Included below: TWRP-flashable stock rom, boot, modem and bootloader zips. KDZ and individual images are also included.​
*There is NO anti-rollback qfuse used in this update... you can downgrade using LGUP HERE. You can also use LGUP to flash the 20B KDZ.
Please do not mirror my files!
20B NOTES...
1. Knock code should be back.
2. Not sure what else has changed yet...
Requirements:
You must have TWRP 2.8.7+ installed to use these files. Thanks to Dees_Troy as always for that. And, of course, you must have your bootloader unlocked for TWRP to work. Currently only H815 EU and (some) SEA variants have official unlock through LG's unlock page HERE. Please do not ask if "model x" is supported... did you unlock via LG's official unlock tool? Yes? then you can use it. No? then you can't... and you should just flash the KDZ instead.
If you have a locked bootloader and want to upgrade... just use LGUP and flash the KDZ. Don't risk it with FlashFire.
Install Directions:
These directions should be used by everyone who wants a rooted 20B system. Don't want root? Then it's probably easiest to just flash the stock KDZ... or just skip the supersu zip in the directions below.
1. Download the boot, modem, bootloader and system zips listed under the download section and place them on internal or external sdcard.
2. Also download the latest SuperSu zip from HERE [Thanks to Chainfire for his auto-patching boot.img version!]
3. (re)Boot into TWRP... don't wipe anything.
4. Backup current partitions: boot, system, data, efs
5. Install boot, bootloader, modem, system and supersu zips- ADD SUPERSU LAST! (Install > select zip > press "add more zips" > select next zip > repeat)
6. After all 5 zips finish flashing you can reboot! (if TWRP asks if you want to install SU, NO!!!)

I may use this space to respond to some questions or add more notes as we go... rather than making new posts in the thread that get lost or go unnoticed.
FAQ
Q: My device shows the wrong software version in settings.. how do I fix this?
A: This is related to the "cust" (customer) partition on your phone. Using TWRP or a "Root Explorer" type app you can delete the current files in your Cust partition then you should have the proper version showing. I am not a fan of adding or flashing the cust partition... so I don't include updated cust partitions in the flashables. The cust folder/partition is in the root of your main directory.
Thanks Boss! U the man, as usual...
thanks @autoprime
I suggest you add a "NEW" on the title of the thread! because it seems the old thread! I had not noticed it at the beginning!
Thanks Auto!

Hi, anyone try Xposed with this version ?
can this modem be used on 20A based ROMS? - because my LTE reception with 20A is pretty weak, wants to slip back into HSPA mode in fringe areas where other phones have worked well.

Hmm slightly odd in that when i go to setting-software info it says the software version is "7 HD 6.1 by S3VEN-234-15". Haven't used 7 HD for probably a month now and dirty flashed this from V20a. Odd, very odd.

Please Read OP!
20B NOTES...
1. Knock code should be back.
2. Not sure what else has changed yet
I install with this method but that don`t change my software version i still have V10e-260-01, but android version is changed to 6.0.
?
Sweet! The KDZ is there
So for those of us with a locked booloader, no root etc, we can just flash / update to 20B via LGUP and retain all of our nothing fun (root and locked bootloader)?
Flashed fine H815P with LG UP.
Thanks,
VW

Sure. You have to go back to 5.1 (there is no method to root 6.0 without TWRP yet). Just download the KDZ for your specific device (You have H815 EU?) and flash it via LGUP. You'll find how to do it in this thread.
If you're back on 5.1 root it using this method, flash TWRP afterwards (2.8.7.0 - You'll find a lot of threads how to flash TWRP, I personally flashed it with flashfire - very easy).
After TWRP and root installed properly go to this thread and follow the instructions - et voila: Rooted 6.0
At least that's one way that worked very well for me Good luck. Don't hesitate to ask questions, but, in fact, there should be everything you need in the threads I gave you. Cheers
EDIT: If you're on rooted and have TWRP Recovery installed + 6.0 (I personally don't know how to achieve that without doing it my way, then you can also use this article - It's actually the same like the autoprime thread)
maybe with the efortless method? injecting root into a MM rom and flashing it?
If your bootloader is unlocked like you said: Flashing TWRP via fastboot should be no problem (don't forget to enable usb-debugging in developer options). After you booted into it, flash SuperSU 2.52 (currently latest beta) and this is all you need normally. Also you can flash the modified kernel from here: http://forum.xda-developers.com/g4/development/kernel-t3232651, or a more modified kernel (same developer) from here: http://forum.xda-developers.com/g4/orig-development/kernel-t3213145
This should root your phone asap.

go here to find kdz's for 5.1, you want v10c or v10d, then use LG UP to flash, make sure you have the USB drivers installed too, found here

LG UP
Didn't I mention 2.52 BETA for SuperSU? *scratch* 2.46 is working on LP (5.x.x) but you need 2.52 for MM (6.x.x). Chainfire did this update mainly for it. 2.60 is also out, if you want: Link - Changelog: Link.
idk if you can downgrade from MM.

Thanks, nice and good info
Nice! Looking forward to seeing it here.
Hello,
Is it ok to update via the update function on the device, even the mediapad has unlocked bootloader and twrp?
Are there any precautions?
Thanks

An OTA update always ships with a new firmware as well. I'm running, and ran, a lot of devices, using TWRP. This I'm really sure that it still is admit always has been: TWRP won't be able to flash the firmware part. Sometimes the ROM update part can be flashed using TWRP, but in general a stock recovery and stock untouched system image unneeded to update through the build in update functionality.

Thanks a lot for the helpful information.
So i'll find a way to prepare myself ?
It's actually the first time in 5 years, that I end up with a device where there's no custom rom available.

Thanks this update:good:, finally its comming..
anyone found a downloadable image of the firmware yet? It's two weeks since official release now, but i can't find the image anywhere.
I've been looking like a crazy person also...
http://consumer.huawei.com/jp/support/downloads/index.htm
Japanese site.
http://m.huawei.com/enmobile/consumer/support/downloads/index.htm
English site.
Maybe if we find a Japanese 5.1.1 firmware, flash it and manually search for update it might work . Can't find one though... :/
Nothing found so far, I have looked for the image too but nothing...hope to find it, or we get the OTA update soon.
One guy in a german forum posted, that he got the update yesterday. So we are maybe not far away.

as he wrote that he had the korean b019 installed before, this sadly gives no clue about the release in other regions. :\
So the options are being patient and hope that the rollout will continue soon. Oooor....just put the korean version on my tab (which hopefully has english language sets anyways), fetch the update and up it to my GDrive. Oh the struggle....
Ah... So Korean or Japanese...
I live in Myanmar and the internet here is so crappy terrible.. Won't be able to download the big files anytime soon.. Would love to test it. :/
But think of how happy you would make us all by being able to upload it to gdrive
i won't find the time today, but i think i might play around a bit with those foreign Firmware installations tomorrow and see how far i get. I really love this piece of hardware, but 5.1.1 is just way outdated and i strongly hope that 6.0 also boosts the overall speed a bit.
Oooooh I hope that they have added multi users and the Screen Pinning feature, which is a Lollipop feature, that they for some reason also have removed.
hmm....i am bit shy to install the downloaded asian rom since i got the Wifi only version (m2-801w) of the tab and all b019-roms i can find are for the LTE version (801l). Anyone knows a download location for 801w b019?
[edit] nevermind, found it on needrom. Just downloading...
So here we are: https://drive.google.com/open?id=0B765h62rQ81INUp0WHVvUFh5VzA
Steps i took, coming from a rooted 5.1.1 (version CUST<something>D003 i think)
- download 5.1.1 Asia release B019 from needrom (M2-801w-V100R001C233B019.zip)
- extract all img files with Huawei Extractor to a dedicated folder
- uninstall superSU
- fastboot to bootloader
- fastboot flash system, recovery and boot img from the extracted file
- reboot
- launch Update Tool
- be scared by some weird asian Update Notes
- install anyway
- success
after installation, the system language is still set to german (as it was on my tab before), so there seems to be no need to work through korean menus for setting the localization back.
You can surely skip those steps above and put the update.zip directly into your /dload folder or on the external sd card, but remember that you need a stock rom for it to work. If you tempered /system or had some custom recovery, you should fastboot flash the extracted img files directly.
