Restore v20 to 100% Stock (!!even for bricked devices!!)

This is a simple method to restore your v20 to stock, I have tried with my bricked H990DS with wrong bootloader flashed.
1. Download .kdz file for your v20 model from the following links. Currently v20 models available are:
F800K, F800L, F800S, H915, H918TN, H990, VS995, H990N and H990DS
H990DS https://lg-firmwares.com/lg-h990ds-firmwares/firmwares/
H990N https://lg-firmwares.com/lg-h990n-firmwares/firmwares/
https://lg-firmwares.com/
2. Search, download and install LGUP ( LGUP_Store_Frame_Ver_1_14_3.msi ) and a file called LGUP_common.dll
2a. Copy the LGUP_common.dll to C:\Program Files (x86)\LG Electronics\LGUP\model\common (May need to modify folder access right)
3. Search, download and install LG Driver ( LGMobileDriver_WHQL_Ver_4.1.1.exe )
4. Completely Power off the v20 ( or to remove and put the battery back )
5. Plug the USB end of sync cable to your PC
6. Press and hold "Volume Up"
7. Plug in the USB-C end of sync cable to the v20. The phone will enter download mode (or Firmware Update). Now you can release the "Volume Up".
8. Run LGUP. The program will regconise the v20.
9. At the file path, click "..." and chose the .kdz file
10.Choose "UPGRADE"
11.Click "Start" and wait until the process is complete.
Now we have a safe method of restoring bricked v20. Hope developers can start trying to root without worrying of bricking the phone.
This method is verified on my H990DS. If anybody successfully flash using this method please let us know. Thanks!

Great thread! Just want to add a quick PSA for this:
This may update your phone to the latest firmware which may patchs the current recowvery exploit. While this will unbrick your phone, you should make sure that you have the a firmware below 10i (w/o patch) to flash. If you still have access to TWRP and don't have a 10d firmware for your device, use this instead.

While this will unbrick your phone, it should be used a last resort for those still using the 10d firmware and have access to TWRP (use this instead).

Thanks for the reminder. Actually it depends on what .kdz is available. For H990DS there is actually v10b firmware for download. So after I flash using this method the dirtycow exploit is still there. Take a look at the filename of the .kdz (e.g. 990ds10b_00_OPEN_TW_DS_OP_1125.kdz is v10b released at Nov 25) Seems that versions below v10i are still ok for dirtycow.

Ahh! Nice! Hadn't considered that. I'll update my OP

Darn. Got my hopes up. No VS995 in the list. No T-Mobile and no Sprint either. I don't need it....yet...but I would love to have a restore method for my VS995. Though I've had an LG G3 rooted and flashing custom roms, kernels, and mods for 30 months and never once restored it to stock so perhaps the V20 will be the same

are you using uppercut for the model .dll in LGUP?
i have tried this method a few times over the last week, no luck. but i was pretty rough with my phone to be honest, no backup and tried all the other v20 variant roms.
right now LGUP detects my phone as a US99610D so will not flash the H990DS firmware, tried to edit the kdz in hex editor for name value but it detects the kdz as corrupt now. any experience with this?

I did not use uppercut because anti-virus reported it detect trojan when I use the program.

so you found a v20 dll file? do you mind posting a link? or how did you get past LGUP picking up v20 as unknown device? or was this not an issue for you?

The LGUP first did not detect the device and asked for driver. So I installed the driver as mentioned in OP. After that i was able to flash the phone with the kdz file.

Pleaseeeee helllllpppppp !!!!!!!

What do you mean?
If this method worked for you & a few other users, it should probably become a sticky rather than closing the thread...
Unbricking a device & restoring to 100% stock is an important feature to most, so if a few users are having issues we should probably help sort out those issues rather than abandoning the thread...

don't close it off, if it worked for you it should work for others that haven't broken the phone quite as much as me (boot, recovery, aboot and system changed).
the dll looks to be a requirement, perhaps uppercut worked for you prior to you AV killing it. i used it despite the AV alert.
so that part works fine, my phone is detected as version US99610d (files used during root attempt) which prevents me running the KDZ with "Error: KDZ file is invalid. US996 -> H990"
i tried to edit KDZ file to change version from H990 to US996 but this just corrupted the file.
i edited the model in build.prop of a rom and flashed it but it failed to make a difference to LGUP.
in a last ditch effort i restored aboot.img but phone is still detected as 996 instead of 990. but now no more twrp or unlocked bootloader.
any idea what LGUP reads the version info from or how to force it to run a KDZ from a different model?

Only issue with that is I think the device would need to be rooted.. which it's not rootable. Which would explain most likely why there's not one already uploaded for the tons of users who attempted to downgrade.

Sadly it'll be very unlikely that root will be coming anytime soon for the H810 if at all at this moment.

Secure booting error after sd card unbrick method
I bought used h811, but it has issue of restarting every time I tired to uninstall any app or tried to go to security setting. So I decided to downgrade it (I have no idea about ARB at that time), the device show h811-21y, So I download h811-10n firmware & use lgup to downgrade after it complete 100% it get bricked, and show qualcomm 9008 on the PC. I then open the device and found out it is h810 written on the motherboard.
I tried almost every qfil mbn files present on the internet but failed.
Then I tired this firmware
LGH810AT-01-V21y-310-410-JUN-20-2016-ARB03+0.rar
and use this youtube method to create raw programme & patch
watch?v=RhG02kmSelk
Then I use sd card method as this youtube method suggest
watch?v=kX2Fm1zEx5E
my device show sign of life but stuck in "secure booting error 1009"
At that point I am totally stuck since I does not get any help with this error on the internet

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

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.
Deep uninstalled all LG soft and drivers
then followed your advises step by step
but still "unknown model"
I need to make first LGup to let find the phone.
I m not sure if i have f600s motherboard.
do you have further advise ?

LG V10 T mobile getting too slow
Salam Bother,
I am new to this and I have joined because of my LG V10 as the mobile was working fine and suddenly it became very slow like if I click on any thing It will take about 2 to 3 seconds before opening and also some times mobile stopped responding and screen became black. I wanted to know if it is a software failure or any thing related to hardware? one thing more phone is turning on and there is no issue with network, wifi, camera even I can use any app on it but very slowly.

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.

LG G7 KDZ file

Hey everyone!
I captured the initial KDZ for the G7, and it's linked below. I can't seem to extract anything from it using the usual tools, however -- it just errors out.
G710TM10d_00_TMO_US_OP_0525.kdz
Also, fastboot flashing unlock_critical seems to work, kinda. No warning dialog, immediate reboot and userdata wipe without nag screen. Once done, however, getvars still says locked and still can't flash anything.

That format is too big, trouble you first unpack and pass it to Google Drive Thank you, I want the wallpaper inside

Any chance you can you point me to the directions you followed to pull the KDZ image?

Please upload it to "Google Drive". This link cannot be used in China.

LG Up is a software suite capable of quite a bit..unfortunatly not if not used correctly..this is a easy phone to customize..however..it's a bit of a handful if it's screwed up..
Start by finding a thread in the forum..try the V10. That used to have a lot of useful how to guides.

G710TM10d_00_TMO_US_OP_0525.kdz
This is for the T-Mobile version of the G7 ThinQ for the US running Oreo Production that was released on May 25th.
To help expand the list of KDZ files for this model, please explain how you accessed this file? Did you run WireShark and follow the packet flow then rebuild the file from the packets? Are you a T-Mobile tech???

I have a new in the box G7 tmobile. I don't know how to pull a kdz from it. Anyone know of a guide? Is there a dll for lgup for the G7 yet?

Still searching for a System DUMP here. Anyone?

Have you tried extracting the TMOUS dz file ? I did replace the LGUPc.dll with your version but dz extract fails.

no , it seems like the way a dz file works changes a bit , i got the dll out of the 10b kdz , and the boot.img dump etc ive used for twrp etc from autoprime, so you cant exztract the dz for now unless you update the tools yourself

You need new LGUP 1.15 or higher to successfully flash and/or advanced dump new devices like LG G7 or LG V35...
still not leaked

Probable solution to VS990 motherboard with H900 or H901 software (marshmello hole)

Hi guyzz I think I've found a solution to the following problems:
1. VS990 board with H900 or H901 software.
2. Settings app crashes, Fingerprint sensor doesn't work, uninstalling an app causes soft boot
But I need help. So anyone willing please comment below.
P.S. as usual this is an experimental solution, so please try at your own risk.
Step 1: I need someone to put their phone in [Qualcomm HS-USB QDLoader 9008], because to my understanding this is the lowest level hardware control for the emmc in qualcomm evices.
Step 2: Once in this mode we need to follow the qfil solution to recover from the hardbrick and install the VS990 software.
But as I'm new to this, I've only found one way of entering the mode. (can't add the image due to xda restrictions -_- please help me with posting the image link )
If there is a software way to do this too, please comment below.

I have the same problem.
I tried many solutions but nothing better.
What is your solution ?

Hi, sorry for the late reply. But my solution is very very risky. It involves willingly hard bricking your phone and just flashing the device with VS990 software using the Q-fil method. But I need testers to actually prove that it works in general and not just on my phone.
But as I mentioned it is very very dangerous. So, unless you have the phone just lying around; I wouldn't suggest it.

OK,
I would try. Now phone is usless.

I'm more than willing to try.
I also have to mention that the ARB is not just in the system, it's also somehow modifying the hardware. I have 2 H900 (both are VS990) boards. One of them is 5.1 rooted, the other is H90021w. I put the 5.1's emmc on the other board and not working. Then I flash the H90021w on the former 5.1's emmc, the phone is working. I won't put the H90021w emmc to the other board as it will ruin the board.
Note: I have a medusa pro box, so I can flash the 90021w anytime if it's bricking.

lg v10 h900&901

Hey, I'm really interested on how this turns out.
So from what I'm understanding, the idea is to get the LG V10 AT&T software flashed (with verizon motherboard) into usb qloader mode, and then to flash the verizon software or the original LG V10 H900 unto it?
I'd say its worth a go, but I don't have a medusa box in case it goes wrong ^^

I've try the very possible way I can think of.
I've take out the EMMC and put a H900 lollipop inside it, not working. Not even any other FW will working, whether VS990 or H901, not after we put H90021w on it. And if I put that EMMC with android 5.1 on another VS990 board, which H90021w is never run on it, it's working fine.
I really suspect the ARB of H90021w is making physical changes on the board, and then only H90021w will working and probably newer FW too. I think that's our only chance. If we can find someone with newer FW willing to help, we can try it. Please check https://forum.xda-developers.com/att-lg-v10/general/calling-help-h90021z-h90022b-firmware-t3881691

Hi and thanks for the support. But due to utter desperation I got rid of the phone about 3 months ago. Now here is all of my research.
1. Get into HS USB mode by holding down both vol up+down....
2. Get QFIL to flash and it should work... P.S. flash proper ones... also dont flash versions below the one that it got messed up with
P.S. I did have a guy try out the board pinching method to get into HS USB... and somehow he got into fastboot and then I got out of contact with him

I know.... but my solution was... as you get into EDL mode all security goes to hell (theoretically) so theoretically you should be able top flash the original ROM that was meant for that specific motherboard, and not the one that was eventually installed during refurbish process
Now technically this should get rid of the unable to uninstall apps and the fingerprint bug....

Maybe.. but the option is very limited on H900. And if we flash the H90021w firmware, there;s no way back.
Basically I really suggest anybody outside US to avoid buying an AT&T phones.

I need to add. Contrary to many believe here, motherboard with VS990 code may not only for verizon, but Tmo and AT&T as well. I've open many V10's board, not once I found H901 or H900 printed on the motherboard (many VS990 and a few F600). Even those H901 which working normally and able to run on the latest official nougat KDZ, are on VS990 boards too.
