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

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.

Finally i have Android Q on my Honor 9 Lite!!!!
I have used the gsi images of treble experimentation and this results
A- If you have Stock Pie Emui 9 on you device this procedure not work. You need to use first another script for downgrade without problem to Oreo (any version, better the older version) and i ll talk of this argument in a specific thread
B- If you have Stock Oreo Emui 8 rom you are welcome and can install without bug Android 10 with this procedure
1) Download and unzip this script in a folder. Note that the script is in the new language of Windows PowerShell (.ps1) and for work you need to install a modified version of adb and fastboot that convert your system to use windows powershell instead of cmd.
2) Install the powershell package of adb and fastboot (setup exe here) and connect the phone to pc in fastboot mode
3) Launch the script clicking with the right of the mouse and select the option "execute powershell"
4) Give all permission to powershell with ALL and confirm
5) The phone at reboot will report that data are corrupted. Don't worry!!! Fix this with a format directly from erecovery and at the next boot Android Q 10 will take the boot!

Whats bug this rom?

Yes, running EMUI 8. On EMUI 9.1 is your phone A/B (=bvs, bgs, etc).
Btw, you can flash and use all Treble GSI ROMs tested in P20 lite section .
(P20 Lite = Honor 9 lite). Also you can install TWRP, recovery, Magisk etc. linked in this section .

Vibration motor fans will be pleased, it's a lot more prominent.
Very slow boot on this build
Boot logo is a bit weird, OnePlus logo bleeding from white to red and alternating
If you install it then reduce the display size, default is horrible.

not a downgrade at all..you went from to a a newly released beta and with that comes all types of issues. this is more for developers who want to start creating apps and work out bugs for their apps. Would not use this yet for your daily driver....once it becomes more stable than absolutely

Install is broken, stuck at the update data. Loops around.
Also no joy with MSM tool but it's late and i'm tired to play about too much.

DO NOT ROOT THE DEVELOPER PREVIEW!
It won't work the same as Android 11 and will end up bricking your phone, thankfully I got the MSM to work, it had said it wasn't compatible with EU build before.

-

Tried on my OP9 last night. Before reading it's not for NA. Even patched magisk after OTA. found out the hard way. Luckily T-Mobile msm came in handy lol.

for going back to A11 issues, just flash manually or run script in *fastbootd to flash both slots a/b (via from payload_dumper) with your latest variant zip.
Oneplus phones make it so easy...
flash 9 simple images
boot a/b
system a/b
system_ext a/b
odm a/b
product a/b
vbmeta a/b
vbmeta_system a/b
vendor a/b
dtbo a/b
most likely one of slots won't flash; ignore
fastboot - w
boot up
*fastbootd (fastboot reboot fastboot)
if not able to boot up in fastbootd, flash recovery img (from payload) in Bootloader.

On Android 11 OOS, clicking on any notification from Notification drawer takes around a second to open the app. For example, if you click on Gmail notification, it takes around a second to open Gmail app. Can anyone confirm if that is fixed on Android 12 OOS Beta?

Dude, it's a first developer preview, there won't be any "fixes"
Developer Preview is like a proof of concept and for app developers to test their apps on different phones on the new OS version.
When OxygenOS12 reaches the betas is when OnePlus will start working on features, fixes, etc.

So no one managed to install this preview on the OP 9 pro ?
It was a 100% miss?

How To Guide [ROOT, Recovery, ROMs...] - S21 FE

How to upload TWRP or root when the phone is branded? Neither method works. Despite the OEM unlocking, the screen for uploading the software is:
ERP LOCK: OFF
OEM LOCK: ON (U1)
KG STATUS: ACTOVE
VOID VARIANTS: 0x0
I've tried everything ... Hepl!
Usually odin throws a bug on vbmet. Attaching the vbmeta disabler file does not help.

Hi, I'm so happy to be able to root my s21 fe with your guide, I followed your twrp guide and this one. I also used the one ui optimization guide.
I only have 2 issues at the moment, whenever I install a magisk module, my system freeses and for some reaspn people cannot connect to my mobile hotspot.
Eo you have any idea as to what might be the cause?

you should notice the audience that the files you provide is specific for your phone model

Hi, in this step:

What vmbeta you flased, i got an error in ODIN about not being to able to open file.

Development Android 14 Beta Program DP 1

We don't recommend installing this on your main device, and especially if you're not familiar with development or alpha/beta testing. There are quite a few known issues right off the bat:

Developer Preview 1
WLAN malfunctions in certain scenarios
Connection fails when casting to a TV display
Red screen is seen when switching from Guest mode to Owner mode in certain scenarios
Manual connection fails after the phone is disconnected from the tablet
WeChat calls may not ring with Bluetooth headsets
Red screen flashes when creating a new calendar
Screen freezes when taking picture with the front camera in WhatsApp
Which devices support the preview?​
OnePlus 11 (all variants except carrier-branded e.g. TMO/VZW)
Where can I get the preview?​Before installing, be aware that installing a developer preview carries a risk of bricking your phone. Make sure you know what you're doing, and backup your files/media before proceeding. Also ensure your battery level is at least 30% and you have at least 5GB space left on your device.
Refer to the forum threads for more information:
OnePlus 11:
Developer Preview 1
Can I revert to the stable version of OxygenOS?​Yes, please read the forum thread of your device as linked above for detailed instructions. Rolling back will completely wipe all your data, so please take a backup before proceeding.
Below is the rollback/downgrade packages for the OnePlus 11. Make sure you choose the correct rollback package for your device and region. We are providing these links purely for your convenience, as rolling back isn't natively supported by our app. After downloading the correct rollback package, move the file from the "Downloads" directory to the topmost directory of internal storage (the same directory that the "Downloads" folder is in). You may also have to rename ".jar" to ".zip".
Then, open Settings -> About device -> Version and tap "Build number" 7 times. This will enable Android's built-in "developer mode" (you might have to enter your phone's PIN/password too). Once this is done, "Local upgrade" will once again be visible in Settings -> About device -> Software update -> top-right button. It it doesn't show up, download & install OPLocalUpdate_For_Android13.apk, and use that to install updates locally.
Rollback packages​The following packages will rollback your device to Android 13, and will wipe all your data. Note that these rollback ZIPs will take you back to A.09 even though the latest OOS13 stable version at the time of writing is A.10. These are not the packages you should download if you're looking to update to Android 14/U.
OnePlus 11 / Rollback packages :
OnePlus 11 NA Version (A.09)
OnePlus 11 IN Version (A.09)
OnePlus 11 EU Version (A.09)
OnePlus 11 GLO Version (A.09)

Rollback packages can be very helpful to convert CN Modele to IN, EU or GLO and also to be flashed to solve softbrick devices.

do you think flashing 2449glo on my 2451 would change it to a 2449glo? or is it just the reverts that work like that?

The rollback packages are very fresh, so untill someone try, it is difficult to say.
But theoretically it could work. At least with 2551 you will be able to get full OTA updates

exactly what I was thinking lololol

In the meantime... here's CPH2451 A14 Stock and Magisk Patched init_boots

@Steve0007
Could you please rename the topic to something more understandable and manageable?
E.g. "Android 14 beta 1 (DP) for OnePlus 11"
I don't understand why you called it "Google 14" - it just makes no sense.
Thanks.

Hey finally I can convert my phone back to the US firmware.

My OP 11 is stucked/rebooting in fastboot mode after flashed 14 beta EU. Booting to black screen. Can reboot to fastboot mode.
Tried to repaired via Fastboot Enhance and roll back package with no success.. I have to ignore some partinations. Any solutions?

Try switching fastboot slot. This fixed for me, although it will take you back to a13

Steve0007​Welp... I can confirm.
The downgrade for CPH2449 GLO for my CPH2451 US boots.
Tested: calls, texts, wifi, camera, bluetooth, etc... all work fine.
About to root, and then upgraded to A.10

Most probably yes if you want to go back to Color os. There is already an Android 14 DP 1 available.

Sorry for not making myself clear, I mean, downloading the apk from the forum and take it to a CN color os device and forcefully "downgrade" it to the 13 ROM - could it be even possible?
Or forcefully for to DP1 NA first and then, down?
