If you use LG Flash tools with 30b KDZ, just find the 20g kit kat KDZ, download, and install it like you install lollipop, takes about 3 to 5 min. i downgrade cause of the same problem, t-mobile my **** battery drain...

Can you re-flash the 5.0.2? My D801 that I am testing has 5.0.2 and currently on battery for 71 hours with light use and still have over 50% battery left. (check e-mails, stream some music etc.)

Yep, you can flash back lollipop, but i dont know about root or twrp or cm12, i dont use it, i think i never will, and to get rid of some of the bloatware that consumes battery, try DEBLOATER, it block from starting some of the tmo apps... good luck:good:

Well first my english is not so good (i speak spanish and french) so explain you step by step the downgrade process... but im going to leave you a youtube video where they explain how to do it easy....
im going to tell you what you need:
- 20G LG G2 TMOBILE KDZ (THIS FILE MOST BE COPIED ON THE FOLDER OF LG FLASH TOOLS 2014)
- LG FLASH TOOLS 2014
- LG MOBILE SUPPORT TOOL
- DRIVERS
FIRST STEP: TURN YOUR PHONE OFF.. WHEN OFF PRESS VOLUME UP AND PLUG THE USB CABLE, THE PHONE WILL ENTER DOWNLOAD MODE, WHEN YOU SEE THE SCREEN OF UPGRADING FIRMWARE LEAVE YOUR PHONE ON THE TABLE AND DONT TOUCH IT.....
SECOND STEP: GUESSING YOU ALREADY HAVE THE 20G LG G2 TMOBILE KDZ, OPEN THE LG FLASH TOOLS 2014 ON YOUR PC (IF YOU ARE ON WINDOWS 7 OR 8 8.1 ALWAYS RIGHT CLICK AND OPEN AS AN ADMIN)
THIRD STEP: LEAVE ALL THE PARAMETERS IN THE SCREEN LIKE THEY ARE, YOU ARE JUST GOING TO CLICK THE FOLDER WHERE SAYS "SELECT KDZ FILE" AND THEN SELECT THE 20G KDZ YOU DOWNLOAD ALONG SIDE OF OTHER KDZ, YOU JUST SELECT THE 20G KDZ (REMEMBER TO COPY THE 20G KDZ TO THE LG FLASH TOOLS 2014 FOLDER)
FOURTH STEP: OK ONCE YOU SELECTED YOUR KDZ YOU HAVE TO OPTIONS, NORMAL FLASH, IT SAVE YOUR FILES, CSE FLASH IT ERASE YOUR PHONE LIKE IS COMING OUT OF THE LG FACTORY (THATS THE ONE I CHOSE)
LAST STEP: ONCE YOU CHOOSE YOUR FLASH, A NEW WINDOWS IS COMING IN A FEW SECONDS ASKING TO SELECT THE LENGUAGE, SELECT ENGLISH, AND OK... LEAVE THE PROGRAM DO ITS THING AND THE PHONE PLUG IN (I LEAVE MY PHONE PLUG UNTIL ANDROID START THE START WIZARD JUST IN CASE)
THATS IT GOOD LUCK IN GOING TO LET YOU A VIDEO OF HOW ITS DOWN

Please Help Me In Urdu I Don't know English

[KDZ] H950PR 5.1.1 compatible with ATT H950 with Video!!!

Update 09/05/15 New User have to choose
H950PR will work if your upgrade from ATT 5.0.1 to PR 5.1.1, But if you try from ATT 5.1.1 to PR 5.1.1 will brick your device
Root your H950PR HERE
Hey guys, many of you have trouble upgrading to 5.1.1, or have a soft bricked phone or just want to have the international firmware (beacuse everybody knows att sucks!!!)
Well Great News, there is a variant H950PR (Puerto Rico) is compatible with us H950 with the same LTE Bands
This is from G4 Forum:
Currently if you have an AT&T H810 there's not offical AT&T TOT. BUT either if you need to go back to stock OR would like to run international firmware you CAN flash the H810PR (Puerto Rico) Firmware on your AT&T H810 either to go back to stock OR would like to have a FULL international experience.

Tips
***Remove the Sim Card and Micro SD
***Copy the KDZ file into LG flash tool folder... Run the programm like Administrator
***If you get "connection to server failed... try again in a moment". That's normal... Move the window (don't press ok or close the windows) you'll see it actually flashing, only wait to your phone reboot

This is great news for H950 users.
As an avid LG user I would recommend not to update with this firmware.
And here´s a little story to back this up:
I bought an LG D850PR version.
I accidentally flashed a tmo (D851) firmware to it.
It got absolutely bricked (no download, recovery, fastboot) (qualcomm 9008), to the point that even using the stock AT&T 10b or 20a tot of KK and LP will not revive the phone.
I used almost every single method to unbrick it (boarddiag, QPST, any flashtool you name it).
So if you mess up and your phone gets Qualcomm 9008 you´re done (Game Over).
Also I am overseas so my phones got no warranty at all and I have a lovely bricked D850PR.

I bricked my phone too, H950, it was my first time flashing a KDZ, and I did something wrong, I sent my phone to LG
But when my phone comes back, I will try again, or someone can try like last option before to send it to LG
I prefer have a kdz/tot for make a clean install, and it is h950pr to h950, not h955 to h950

I know... My phone was D850PR and the problem is there is no tot to extract the files from. Only KDZ format so I cant repair my phone with the original KK D850 files. Nothing happens it doesnt boot to fastboot or download. So I wouldnt suggest the flashing.

I just check and see that you have LGD850PR20A.KDZ, why you cant extract the files? I did it, I extracted from 950PR.KDZ some files like boot.img, laf.img recovery.img etc.... the reason why I cant use all the programs you said, is because the AP chipset is not supported (SP810 MSM8994) but the G3 is supported (MSM8974AC).
I know its hard to find information about it..... I hope someday we can get a tool that can fix
Well, that was my experience and I got brick

Boarddiag uses .mbn files.
How would you extract .img files from a KDZ.
Cause with LG Firmware Extractor you extract .bin files and only system.img
Boarddiag cant use KDZs because they extract in too long or too short files and with wrong extensions and weird names.
I even paid for online remote repair and the dude said its weird that with D950 normal files we couldnt repair. My phone is clean esn too.

I downloaded the SRKTools and tried to find the code to flash the partition and I found this
Code:
rename_to_bin.bat
rename_to_img.bat
So I think it use the .bin files and only rename it to .img..... same like LG Firmware Extractor, it merge all the system.bin files and rename it to .img
That was my conclusion...
It is hard to fix a QHSUSB_BULK, but you got Qualcomm 9008 AKA Super Bricked Mode XD same like me, for that we have to fix the corrupt bootloader, but I said F*** it lol Warranty!!

Haha lucky you, you have warranty. As I told you earlier I was left with a beautiful brick. Im waiting for the arrival of an Octopus Box, its got integrated Jtag. So I hope I can help others if I manage to unbrick mine. For now I'm really really pleased with Flex2 its an amazing phone.

SO i can try with this kdz?
Sorry i didnt understand. I can use this kdz to update h950 att to a stock and clean rom?
Or maybe i can get brick my phone? Thank you.

read the post above.... I bricked my phone and sent it to LG because if you do it wrong... you will get super bricked mode with no solution ATM
The reason why I failed..... I tried under Windows 10, I had an official LG tool installed (I should first unistall it) and was my first time flashing a KDZ.... I repeat if you know how to do it then Go ahead

hey, talking with @joseacuna, he said me:

yes, that is the G4 forums and like I posted "ATT G4 (H810) users can use the KDZ for Puerto Rico Edition (H810PR) because it has the same LTE bands to work"..... So we have the ATT Flex 2 (H950) users, in theory, we can use the Puerto Rico KDZ (H950PR) cause it is the same hardware and software
Read the op, I posted that link like a guide, the kdz file is in the first post

Has anyone tried?
I'm wondering if anyone has tried and succeeded in flashing this on a h950. I see people have failed but don't see where anyone has said it worked.

Need stock KDZ for h950
If there is a way to create a kdz from a phone running stock firmware i'm running stock still so if you tell me how to create one i will.

UPPERCUT: Add Any LG Device to LGUP for TOT/KDZ Flashing (G4|G5|G6|V10|V20|MORE???)

}
UPPERCUT allows LGUP to instantly work with a ton of different LG models. No more hunting around for specific model files or being stuck without your model being detected. Simply install LGUP. Double-click the UPPERCUT.exe and LGUP will open and detect your device.​
Information:
What's LGUP? LGUP is LG's internal Windows-only tool for flashing LG devices with stock firmware in KDZ, DZ and TOT formats. Previously extra installers and unique settings were needed for each model. Many less popular devices didn't have the files needed to work with their device.Well with UPPERCUT just double-click the EXE and LGUP will open and recognize your device.
Requirements:
1. Windows computer or virtual machine.
2. LG's Windows USB drivers installed and working.
3. LGUP 1.14 installed
4. LG device must show in Windows Device Manager under "Ports" as a LG Serial COM port.
5. KDZ, DZ or TOT file for your device.
How-to:
1. With all requirements above met... download and unzip UPPERCUT.
2. Double-click the UPPERCUT.exe every time you want to use LGUP. It's that simple.
Downloads:
UPPERCUT | LGUP | LG G5 Files | LG USB Drivers
When LGUP works for your model please post it in the thread! List:
your model (H850, D852, F600L etc..)
the software build you were on before flashing in LGUP (10A, 22C, 30B etc..)
the KDZ or TOT name you flashed using LGUP (H91810i_00_1202.kdz etc..)
Versions:
1.0.0.0 - Supports LG devices using a MSM 8996/8994/8992/8976/8952/8939/8937/8916/8909/8226 chipset. Street Fighter 2 SFX.
Let me know which combos do/dont work for you... UPPERCUT version, LGUP version, Current phone software version and KDZ/TOT software version and if the KDZ/TOT is custom or official.
Devices Supported:
G4, G5, G6, V10, V20, Flex 2, G Pad X, K10 and many more!
FAQ:
Q: Why isn't this working?
A: UPPERCUT requires LGUP 1.14 (not 1.11) installed in its default location prior to running.
Q: Why isn't anything happening when I press the boxing glove picture in this thread?
A: Really? ...
Q: What is this?
A: This is the simplest way to make LGUP work with your LG device.
Q: Refurbish option in LGUP doesn't work, what now?
A: Boot into stock recovery after the flash finishes and perform a factory reset. This is the same outcome as if Refurbish was selected.
Q: Why does this TOT file keep failing?
A: In most cases you're either trying to downgrade and it has been blocked by your phones download mode (not anti-rollback fuse.. that is different)... OR you are trying to use a custom-made TOT file which is not official or signed by LG. Flash an official KDZ instead. Do not ask for KDZs in this thread.. not the place.
Q: Where can I find a KDZ for my phone?
A: This is not a KDZ thread. Take the KDZ questions elsewhere.
Q: Why is my anti-virus scanner flagging this?
A: It's a false positive. Scanners like Kaspersky know better and don't flag the app but some others do. See post #59 for more info.
Q: Why is my device's model not detected in LGUP?
A: Make sure your devices chipset is supported by UPPERCUT. All models and software variants may not be supported even though chipset is listed.
If using a confirmed working device with UPPERCUT but your device is still not detected in LGUP you may have a "corrupted" misc partition...
as a last resort it has been confirmed in post #70 that wiping misc then booting into download mode allows the device to be detected with UPPERCUT + LGUP 1.14. This may not always work. And without root you cannot do this.​

everything from original 1.0.0.0 + 1.0.0.1 is added into NEW final 1.0.0.0 which is now added to OP.
if you cannot downgrade with the current 1.0.0.0... then using 1.0.0.1 wouldn't have worked either.
some users have reported downgrading directly from N to M working. I have seen H850 users in other threads say they can downgrade without unlocking the bootloader or needing TWRP to flash the old M bootloader. Can anyone else confirm? What about other G5 models? What about other non-G5 devices?
I can confirm that H830 CANNOT downgrade from N to M without unlocking the bootloader, rooting, installing TWRP and flashing the M bootloader/bootstack first. I've used UPPERCUT to flash everything.

LG v10 H901 (with Korean board F600s) Update to 6.0/7.0 without Brick

Salam Everyone!
Today i'm going to post About Lg V10 model which says it is of T-mobile (from boot animation) but when you remove battery it show Model H901 (Made in korea) So it is huge confusion between users of this phone. Let me clear this one first, your phone consist of board same as LG v10 Model F600s so if your lg Bridge shows an update of something like "F600S30D 05.27.2017" dont worry it is saying this according to board requirement (Warning: Never update your phone using LG Bridge otherwise you are going to brick your phone). LGup is best for updating LG firmware’s.
Now let’s come to the point on how to update this model to Marshmallow and Nougat. And one thing Do this step by step as described in steps below (one thing i'm not a developer i just do little internet research and with help of some friends i was able to do it without bricking my device).
This you need is for update is Kdz for Marshmallow and Nougat and LG up Software.
Installing and fixing LGup ‘unkown model’ problem:
I've seen some people complaining about lgup not picking up this model so here is a fix you can do it to make it work:
Download LG up software using all the links given below:
Now do it as I say.
- Install LG UP LAB Ver. 1.10
- Install LG UP Store Ver. 1.14
- Install LG UP Ver. 1.14
- Now most important is this file LGUP_8994_DLL_Ver_0_0_3_23
(Now here is a Check whether your LGup is installed properly or not scroll through follow the following address and check is there “Common” folder have File “LGUP_Common.dll” If not please try this process again.
Address: C:\Program Files (x86)\LG Electronics\LGUP\model\Common
And after you are done with installing LGup now time to check if this is working remove back cover of your phone (unplug your phone from USB cable, remove the battery, insert battery while pressing the Volume up button and now plug the USB cable. Your phone will turn on automatically with Download Mode on and yes LGup will recognize your phone immediately without any further delay. Showing Model as “H901”
How to check Phone model using Lg info app:
There is one little check you have to do is… go on play store and download Lg info app install it and check your phone info.
Scroll down and See “Provider Name”: (Now here we will see the exact model number of your phone)
- If it shows SK Telecom This means your phone model is LG F600S aka LG V10.
- If LGT this means your phone model is LG F600L aka LG V10.
- If KTF this means your phone model is LG F600K aka LG V10.
Now after Confirming Model Number Now download the relevant firmware but keep one thing in mind do it step by step don’t try to flash direct Nougat on Lollipop okay this will brick your phone as well.
Updating Marshmallow from Lollipop (6.0 from 5.1.1Stock):
As assumed you have downloaded your concerned firmware (you can do a little search on Google and you will find relevant kdz if you need further just p.m me)
- As I have LG F600S aka LG V10 so I will tell you what steps I used.
- First download F600S20l_00_0503.kdz
Now same take your phone in download mode and let LGup recognize it now Select it under BIN File and (Check the Upgrade option) now press start and It will start upgrading. Leave it for a while and let it complete. Now your phone will turn on without any brick  V10 will download some OTA software updates (as it happened in my case). Check your software Update it will surely say 6.0 
Updating Nougat from Marshmallow (7.0 update):
Download the latest firmware from LG firmware website that says “ 7.x Nougat” in my case it was “F600L30e_00_0517.kdz” (Model F600s)
Do the same as you did while updating to Marshmallow. It will successfully update your phone to latest version. No further complications are there in this step it is so simple.
Some Warnings:
- If you are going to use my technique to update please do it carefully do not skip anything.
- I’m not responsible for any kind of brick phones SD cards. As I said I’m not a developer I’m just like you guys was looking for update my phone and done it will little research and help.
- Do not unplug your phone while LGup is updating your phone.
- I’m not developed any software or any update so it is all online stuff nothing personal: D
- And I’m here to help other please feel free to ask anything form me  I’ll try to help as soon as possible 
You can message me on Whatsap I’ll create a group for help on whatsap as well.

@hapyfaroq as you mentioned, you have flashed Marshmallow F600S20l_00_0503.kdz !!! and for Nougat you flashed F600L30e_00_0517.kdz !!! which are totally different models. could you please recheck if you typed F600L30e_00_0517.kdz istead of F600S30D_00_0510.kdz

Everything is double checked and then posted so no mistake in the article

Mine is KTF but now running fine on F600L Nougat (and the pcb says it's F600L), not sure what's really happen here. It was H901 Tmo before got bricked.

Thanks @hapyfaroq @runningnak3d for your time & help
Failed several times and gave up with LG UP. So i took my phone to a mobile service center who is good at software flashing. i gave him nougat kdz F600S30D. He converted kdz to dz format and flashed with Octoplus box. my mobile was on 5.1.1 android and directly flashed Nougat. Booted flawlessly and no network problems as well Everything is working just awesome. attached my video of Nougat Overview

Salam Everyone!
Today i'm going to post About Lg V10 model which says it is of T-mobile (from boot animation) but when you remove battery it show Model H901 (Made in korea) So it is huge confusion between users of this phone. Let me clear this one first, your phone consist of board same as LG v10 Model F600s so if your lg Bridge shows an update of something like "F600S30D 05.27.2017" dont worry it is saying this according to board requirement (Warning: Never update your phone using LG Bridge otherwise you are going to brick your phone). LGup is best for updating LG firmware’s.
Now let’s come to the point on how to update this model to Marshmallow and Nougat. And one thing Do this step by step as described in steps below (one thing i'm not a developer i just do little internet research and with help of some friends i was able to do it without bricking my device).
This you need is for update is Kdz for Marshmallow and Nougat and LG up Software.
Installing and fixing LGup ‘unkown model’ problem:
I've seen some people complaining about lgup not picking up this model so here is a fix you can do it to make it work:
Download LG up software using all the links given below:
Now do it as I say.
- Install LG UP LAB Ver. 1.10
- Install LG UP Store Ver. 1.14
- Install LG UP Ver. 1.14
- Now most important is this file LGUP_8994_DLL_Ver_0_0_3_23
(Now here is a Check whether your LGup is installed properly or not scroll through follow the following address and check is there “Common” folder have File “LGUP_Common.dll” If not please try this process again.
Address: C:\Program Files (x86)\LG Electronics\LGUP\model\Common
And after you are done with installing LGup now time to check if this is working remove back cover of your phone (unplug your phone from USB cable, remove the battery, insert battery while pressing the Volume up button and now plug the USB cable. Your phone will turn on automatically with Download Mode on and yes LGup will recognize your phone immediately without any further delay. Showing Model as “H901”
How to check Phone model using Lg info app:
There is one little check you have to do is… go on play store and download Lg info app install it and check your phone info.
Scroll down and See “Provider Name”: (Now here we will see the exact model number of your phone)
- If it shows SK Telecom This means your phone model is LG F600S aka LG V10.
- If LGT this means your phone model is LG F600L aka LG V10.
- If KTF this means your phone model is LG F600K aka LG V10.
Now after Confirming Model Number Now download the relevant firmware but keep one thing in mind do it step by step don’t try to flash direct Nougat on Lollipop okay this will brick your phone as well.
Updating Marshmallow from Lollipop (6.0 from 5.1.1Stock):
As assumed you have downloaded your concerned firmware (you can do a little search on Google and you will find relevant kdz if you need further just p.m me)
- As I have LG F600S aka LG V10 so I will tell you what steps I used.

Hey what if I have a T-Mobile H901 with VS990 motherboard in it? By the sound of things, I would need to flash vs990's kdz. However, wouldn't Tmobile's h901 kdz work as well? I don't understand how your modem and boot screen img(tmobile) wouldn't be affected by flashing f600 kdz to tmobile phone.

bro as i explained in detail that flashing H901 kdz on phone having different board in it cause it a brick so better to flash such kdz which is compatible with the board.... Be careful double check with your board model. (this is the most important part) Keep that in mind that if you are going to flash some other kdz it will not work and will brick your phone.

i have everything ready but lgup never found the phone as a MODEL.keep saying "unknown model".
i ve checked lg bridge it founds 2 updates (im on 5.1.1) , lgbridge founds both 6 and 7 updates.
i've downloaded the kdz file according to the bridge and and phone provider(tmobile)
but i don't know if i can flash it with LG flashtool besides LGUP.
Because i can not pass "unknown model" issue.

Read the Article carefully it says never update your phone using LG Bridge it will brick your phone, and for kdz please search lg firmware on google and download the relevant kdz as per the model of your Phone's board. Don't waste your time downloading wrong kdz and lg up is hard to setup... keep on searching you will sure find a fix soon. Do a deep google search (as i did) you will figure out what is the problem behind Lg UP

Wassalam Farooq
The issue is that my LG info says its : T-Mobile H901BK
It's on 5.1.1
I have the correct KDZ for Tmobile.
Using a win 10 64 bit OS.

Bro first of all you need to confirm your phone board model using Lg info app ... you can find it on playstore for free and for lg up do all as i said above then turn off your phone remove the battery... plug in the usb cable... now install the battery while pressing volume up button it (make sure you lg up software is running) then your phone will directly go into download mode and Lg up will sure recognize your phone model but first of all confirm your phone's board model.

[Guide] LG V20 Back to Life [Download mode] [LG Flash tool] [Unknown model in LGUP]

Overview:
Did you got that annoying "Unknown Model" in LGUP and now are struck download mode. This usually happens when you try to root with dirty and do something wrong to mess up entire process.
What Actually happened in my case:
I had a friend who tried to root his H990ds with dirtysanta but due to some issues the whole process messed and his phone was struck in download mode. Phone was unable to go pass LG logo and boot. LGUP was unable to recognize the phone. We tried different ways, different drivers but all in vain. So, we were able to do this process and it worked finally.
This process was tested with H990ds. Here files for H990ds are provided. You need files respective for your model.
Possible Cases:
So I will not waste the time. Possible cases:
1: LG V20 stuck on download mode and it is now not being recognized by LGUP and you can’t do anything, because no other tool is available.
2: You installed a custom ROM and now LGUP is not recognizing it. You want to go back to stock and can’t do it.
3: Anything bad happened during flashing process, PC restarted, phone went off or whatever. And now you can’t bring it back to life.
¬ Or
Other cases you faced.
Read 4th post before proceeding,
Before asking a question, first, see FAQ in 3rd post. In that way you can save a lot of time.
Things You need:
1: LG UP
2: Uppercut
3: Drivers
4 : LG Flash tool (the one used to bring LG G2, G3 back to stock).
5: LG Firmware extract tool
(All above files can be found in 2nd post)
6: Stock ROM for your device.
I used V10g KDZ for H990ds. You need to download KDZ of your specified model.
7: Dll specified for your model (in 2nd post H990ds dll is provided)
Process:
First:
Uninstall all other tool, previous driver (including other phone’s too). Restart PC
Just to avoid problems. I tried this process many times on Windows 10 64-bit and it always worked for me. So it has no problems with new Windows OS.
Now follow procedure in exact order.
1: Install Latest LG drivers.
Put Phone in download
(Hold Vol+ and connect to PC while it was powered off).
Wait until it finishes installing drivers. Change COM Port to 41.
{
"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_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
( Refer here for changing this, If you can’t understand that.)
Now DC it from PC and keep it staying in Download mode.
2: Install LG Flash tool and copy megalock.dll to installation directory or it won’t work.
3: Install LGUP_Store_Frame_Ver_1_14_3.
4: Extract LG Firmware Extract and copy Stock KDZ to that folder.
5: Run WindowsLGFirmwareExtract.exe. Click on Open.
6: Select your KDZ. Select all content off kdz.
7: Click on extract kdz. Wait for kdz to extract. You will notice a dz and LGUPc.dll.
8: Run LG Flash Tool. Select Manual Mode.
9: Select LGUPc.dll in dll section.
10: Select .kdz in S/W section (You will have to select show all files to make .kdz visible).
11: Now Begin downloading by pressing "Yellow Right Arrow". Connect phone in download mode.
The step will fail at 4%. Now Disconnect phone. Do not turn off phone. Just disconnect it.
12: Now exit and start LG Flash Tool again. Select Manual Mode. This time Select LGUP_H990ds.dll this time for dll section
(You need different dll for different model. For example, "LGUP_VS995.dll" for VS995 variant )
13: Now select that extracted dz in S/W section this time. Click on Start Arrow. Connect phone.
14: This time the flashing will begin. It will go upto 150%. Wait for it to complete.
After flashing phone will boot into a screen with a big 2 on screen. After some time it will change into big 3.
15: When it changes into big 3. Pull the battery and start the phone.
Your phone should start after some time. It should be detected by LGUP.
For Phone Stuck at Big 2:
If your phone stuck at big 2 during process then you will have 2 choice, either restart process from start or flash this time with LGUP. Because phone is now running a fully stock firmware it should be detected by LGUP completely. You can simply flash kdz with LGUP and it will not show big 2 on screen. You need to start LGUP with uppercut.

Attachments:
1: LG FlashTool
2: LG Firmware Extract 1.2.5
3: Uppercut
4: LGUP 1.14.3
5: Driver 4.2
or Mirror for Drivers (All Version) (Use latest)
DLL Files:
LG H990DS DLL
LG VS995 DLL

FAQ​
I got confused on which Flash tool to use and with this megalock stuff?
Ans: Thanks, you asked, Just download LG Flash Tool attached in 2nd post, unzip, install tool, there will be a megalock.dll too, copy that to installation folder (by default that's "C:\LG\LGFlashTool") and overwrite, (written in install. Instructions too inside zip).
This method isn't working for me, what shall I do?
Ans: The possible reasons, for that not working, might be,
A: You didn't installed drivers properly, try uninstalling old drivers and restarting after that.
B: LG COM PORT isn't set to COM41, here is guide for that.
C: And Most important, You are not following steps in the order in which they are written, so read carefully.

I followed this guide through all the steps since my device was unknown in LGUP (patched).
Now I'm stuck with nice LG boot logo (not even the warning screen), TWRP and unlocked bootloader with working fastboot commands.
No matter whichever rom I flash through TWRP, I end up on the LG logo when I reboot, rooted or not. I have tried H910_10r, LOS 15.1, LOS 14.1 with respective gamma kernels or without and I can't get past the LG logo. Also, there is no LG Flash tool compatible DLL for H915 / H910 / H910PR. Just only H918 on the website you mentioned.
I have 3 USB Type-C cables which all work with QPST factory reset for Lenovo ZUK Z2 and I've tried both USB 2.0 as well as USB 3.0 ports on my two laptops. Both have drivers test-signing enabled and I've flashed kdz's in the past without any hassle.

Try using dll from common folder in patched lgup. Use that dll with dz. Extracted dll from kdz with kdz.

Alright I used the LGUPc.dll with the kdz and ended up with error at 4%
then I selected common dll and the extracted .dz file.

You said you were rooted before. Which means you aboot is from us996. So you need to flash us996 kdz (along us996 dz) using this method. If you want to use that kdz you have then you need to restore your abootbackup.
I recommend download us996 and flashing it. After that you're phone will be detected then lgup then you can flash stock original kdz if you want to.

I have US996_10f kdz as well and its in the same boat. Same error at 4%
I'm now fully stock but the download mode shows 633A B50 on the status screen.

Can I use this to convert ls997 into us996 for bootloader unlock and root purposes?

Only if you haven't taken the update which bumps anti-rollback up. In that case you can't unless there is us996 kdz with same ARB.

Nice Write-up! Thank God this hasn't happened to me, I have only needed to use the LGUP to unbrick my phone. I did have trouble getting Download Mode after millions of various upgrades. What I found out is that if you have a flaky cable you might never get into download mode, so make sure to try a couple of USB-C cables before you give up and start from scratch. It just might be your USB cable.

How would it work for a h910 in this state of display whitenoise static (link to first of several posts)?
What would be different for my bricked h910? and e.g. This site has only files for the 918.
