Hi,
I tried to upgrade my LG V30+ US998 to android Pie via TWRP but after the upgrade and system reboot the device got stuck in LG logo.
The download mode isn't working (device not being detected).
LGUP shows the device as "unknown" and adb is not detecting the device either.
I can't boot into TWRP anymore and flashing via LG flash tool 2014 fails (asks for server connection!).
I installed all the tools and LG mobile drivers on another computer and had no luck!
Do I have any chance of recovering my phone?

Why can't you boot to TWRP?
Use the hardware button dance, if you must.
__
Are you using the latest Dev Patched LGUP from the Pie KDZ threads? Uninstall any prior version and read the instructions carefully.

Your phone is not bricked. No one ever bricked their phone trying to update to Pie. Being stuck on logo is not bricked.
Tons of people get stuck on logo. So what? Then they re-flash 20h or whatever.

I teied the button dance and after i confirm the third Yes prompt device reboots to LG logo again.
I used both the pie patched LGUP and dev LGUP.

Reinstall LG Mobile drivers again.
Uninstall Dev Patched LGUP completely. Delete the folder from Programs/LG Electronics to make sure.
Re-install the Pie Dev Patched LGUP. Use the SetDev.bat in right click Administrator mode.
Then REBOOT the PC. You've installed two major PC components and Windows needs to process that.
Go into Download mode MANUALLY before opening LGUP. ONLY open LGUP from the desktop shortcut, not the folder icon.

I tried every possible combination of the available apps.
Phone in download mode not recognized by the computer (tried on two computers).
If I connect the phone into the computer and open the LGUP it shows as "Unknown"
For some reason TWRP got wiped out after flashing Pie rom and I cannot boot into twrp to flash the old Ore rom.
I finally managed to fix my phone.
Below are the steps:
1- boot the phone im fastboot (connect to tbe computer via USB cable and press and hold both power and volume down until phone reboots then quickly release the power button and hold the volume down until the fastboot menu appears)
2- copy the twrp image into adb folder and rename to twrp.img
3- download and copy a working rom (in zip format) and paste into micro sd card and insert into phone
4- open the command prompt as administrator and navigate to adb folder then type the following commands in sequence
Adb devices
fastboot devices
fastboot flash recovery twrp.img
fastboot boot twrp.img
Now your phone will boot into twrp and you can install the Oreo zip rom into phone and enjoy using your LG phone again!
Thank you!
I've added this to the US998 Pie KDZ thread. That KDZ is very wonky. It's the only Pie people have problems flashing. Probably because LG has not yet released Open Market US998 and the one we are using is technically for U.S. Cellular US998.
I had no trouble flashing it myself -- on my backup V30+(former LS998) going straight from Nougat (never updated, it was my backup phone) to Pie through Dev Patched LGUP Refurbish mode. But lots of other people seem to have problems.
On my daily phone, I'm still on rooted stock Oreo with Magisk and Xposed mods.

I think part of my problem was the Pie ROM.
I have the US998 UCL version and I've read that the LG only released the Pie update for LG V30 US998 model with the Buyer suffix (1CL, UCL, UCK) and US998Z (UCL) only. But I could be wrong!

Right. LG has not yet released the Open Market USS98 KDZ yet. Theory is LG is waiting for the Sprint Pie KDZ to be accepted by Sprint. Open Market USS98 is the official North American carrier unlocked variant that needs to work with all carriers. So, Open Market US998 Pie KDZ (if ever released) will incorporate testing results from the long-delayed Sprint LS998 Pie KDZ (whenever it's finally released).

Hey guys, Been on XDA for a long time but never really had any issues until now.....
So I took the lollipop OTA and was waiting on a root method. I got the G3 rooted using the guide here http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772?nocache=1
Everything went fine and I was rooted and messing around when I went to uninstall the Xposed framework (not even sure why I wanted to...) anyway, once I hit reboot the phone rebooted but then got suck on the LG boot screen. I tried getting into stock recovery, but it showed up on the screen quickly and went back into the boot loop. I can't access download mode either....when I try it takes me straight to fastboot.
I am no adb or fastboot expert but I figured I would at least use adb comands to pull all the media files off of my internal memory (pics and vids of the kids) then use the LG flash tool to go back to stock. But when I open the command prompt adb devices doesn't show any devices listed....so no go there. Then I tried to reinstall laf.img but the fast boot command just sits there "waiting for device" and nothing ever happens.
I have literally spend all day at work trying to fix this...I've searched all over the forum and Google and can't find a method that will work for my situation. Please excuse my ignorance if I am not using these terms correctly. I really just want the pics off of my internal memory. I'll deal with unbricking later....but it seems like if I can't access recovery or download then I might not be able to do that either. Can anyone help? THANKS!
If you can please upload the screen your phone is on. Or possibly describe it a little more. If you can get adb working you can pull your whole picture directory(s). What OS are you running? Like windows/mac or linux?
---------- Post added at 08:11 PM ---------- Previous post was at 08:02 PM ----------
On your computer if your on linux I have some files that I made that may help you. They may work on mac. If your on windows I will go ahead and link a tool. The files go and reboot your phone via adb and fastboot commands.
I'm on windows 7. when I go into recovery the screen shows Recovery mode. Then at the top, Error : boot certification verify.Secure booting error. Then the screen goes black and the led cycles red-blue.
If I try to get into download mode, the phone goes right to the fastboot screen. But then I cannot verify the device is connected by either adb commands or fast boot commands. Thanks
When your on one of the screens that work try these commands:
adb devices
fastboot devices
This should tell you if it is connected. Also what recovery are you running?
Ive tried both commands and neither show any connections. The fast boot and adb devices commands both return a blank line. and any other commands return an no connection error.
I tried installing twrp after the initial rooting process but it wasn't successful... but at that point I could still boot into the os. Then I screwed around with the Xposed framework and I've been stuck ever since.
I can't think of anything else if you can't get any connections working then you can't extract your photos and you can't boot. Only thing that I can thing to do is to go to sprint a get a new phone. If you don't mind please explain how you installed it to prevent more bricks.
Did u make sure u have good working version of the lge USB drivers? If u do, when u hold power up when phone is off and plug in the USB cable, your phone will turn on w the update firmware screen. Under com ports in device manager u should see your phone. Make sure u change your device port number to 41. Then flash tool will work.
Thanks to those who tried to help! Just wanted to give an update......
Here's what happened...I rooted ZV4 when I first got the phone and never installed any other roms or custom recovery. Root was broken when I installed the ZV6 OTA (I knew that would happen going in). So then I took the ZV8 OTA in hopes that I would be able to find a working root method after it was out for a while.
I rooted stock ZV8 with the guide listed in the first post (which has been updated since I originally used it). No problems.
I tried installing TWRP with the file I got from TWRP website specific to LS990. It failed and I can't remember why at the moment. I am still confused if I needed the bump'd version or not and I still am not sure what bump'd is (I've read about it) but that's my problem....
I was playing around granting SU permissions to all my apps that lost it at the OTA update and I wanted to uninstall the Xposed framework thru the app since it does not function in ZV8. When I went to uninstall, the app did its thing and rebooted the phone....and it never booted back up again.
At that point there was no access to recovery or download mode. It went straight to fastboot and I was never able to send any commands that did anything of use. I tried 3 different PC's, installing android sdk (with adb and fastboot) and LG drivers on all of them and I never got any communications to the phone except for one time where I was able to send fastboot commands that showed on the phone screen...but it kept hanging. I let it go for hours and it never finished/did anything. I tried fastboot commands to flash laf.img and recovery.img but nothing worked. I even used a Ubuntu live usb on 2 different PC's to just get the data off and try adb and fastboot but no comms there either.
Somehow I must have corrupted some of the partitions in the internal memory and I was not able to recover it. I know just enough to get me into trouble apparently. I've been flashing phones since my original Sprint Windows 6.1 touchscreen and never bricked one until now LOL.
I took the phone to Best Buy because I have the geek squad protection...but it is worthless for software issues...they wanted $150 deductible to replace the phone with a refurb...cheaper than a new phone but still worthless in my eyes for this issue. Then I went to sprint where the tech worked on it for 2 hours before he finally gave up. Sprint replaced my phone for $75...so not too bad. But I had to get their TEP, as luck would have it...it is open enrollment month for the protection so they gave me a $75 credit on my bill.
So the moral of the story...be careful messing around with the Xposed framework.
Just to let you know, it was your aboot. ZV8, L, aboot blocks bumped. So twrp is already bumped, err false signed. Well open bumped is way LG patched aboot.
Also windows sucks, use linux. Lol at less for fastboot
I'm having this exact problem too. Root went fine, but then when I flashed the recovery I got this same problem and it boots straight to Fastboot (when I'm lucky enough for anything to happen). Someone please help!
Run this command fastboot boot <recovery name here>
It will set your devices boot.img to twrp for one reboot then it will go back to your normal boot.img.

Did you try changing the action mode setting on the flash tool from "update DL" to "board DL"? Also make sure you have latest lg drivers and be on at least windows 7. I tried on vista and it will not work because you have to manually change the com port your device is on to com41 under the port section in device manager. Lgflash tool will say 41 but u actually have to change it. Let us know what happens. Oh and be sure phone is off and hold the " up" volume key then plug your phone into your computer

Hello Im posting my solution to how I had fixed my bricked LG G3 LS990. I bricked it a few days ago and searched tons of forums and youtube videos and it was tough trying to find a solution for this variant of the LG G3.

Thank you so much for your help! I bricked my G3, unfortunately, and found your steps! I am currently only getting the security error. I tried to reflash using lg flash tools, but I get a 'Model information check failed' error when i try to. I'm definitely using a tot file for the VS895 (which is my version). If there is any guidance you may be able to provide I would be very grateful!!
thank you!

Hows it going, have you tried selectiong "Board DL" instead of "Upgrade DL" on FlashTools?
Or the best thing id try to do is use the LG Firmware Extractor and using the TOT file for your model phone select and extract the following files..you may may have to change the extensions to .img after extracted
boot
aboot
recovery
laf
dbi
modem
persist
primartgpt
rpm

If any lg drivers are showing in device manager try uninstalling them and install the official drivers for your device at the lg website or google the most recent drivers and retry my steps. Does anything phone in device manager at all when you connect your phone
Hi,
I have a lg G5 H850 stuck into "fastboot for bootloader unlock" mode and recovery or download mode are not working, I tried to recover it by unlocking the bootloader but the OEM unlock option is disabled so I cannot flash anything.(device locked error error message)
I saw a YouTube video yout ube.com/watch?v=ImJ1xXXzV6s with my exact issue but he is not responding to my messages.
Is there any option to unbrick this device?
Thanks a lot in advance to all!

Hi guys,
it's been more than two hours that I seek the solution to this same problem with next to me the LG G5 bootllop.
All other solutions give nothing:
- unlook via fastboot makes a mistake because the debugging option is not enabled
- the download mode does not remain more than 15 seconds
Guys, have you found a way out of this problem?

You can try getting the .kdz for your phone (e.g. off lg-firmwares.com), use the WindowsLGFirmwareExtract tool to extract the .dz out of the .kdz, then use the tool to extract the laf_6.bin out of the .dz. You can then flash this in fastboot mode using a command like
Code:
fastboot flash laf laf_6.bin
Make sure to use the same .kdz as your running firmware.
I had the same problem with Download Mode as you (restarted after 15 seconds). I extracted laf_6.bin from the H85030e KDZ firmware (whose boot stack was in use), and flashed its LAF (i.e. Download Mode) volume over the laf partition. After this Download Mode stopped restarting after 15 seconds, and I was able to use LGUP (and you would be able to use UPPERCUT) to flash the full KDZ.
(I proceeded to start the phone in bootloader/fastboot mode and flash TWRP recovery as well, with my unlocked bootloader.)

interesting. I am in Bootloop from two weeks. Tried to much time lineage 17.1 and then leave the phone so many hours in order to boot in lineage that at some point it won't enter system anymore.
So I passed to LGUP that works only with UPPERCUT and only with UPGRADE functions even if I installed all the drivers.
Maybe I need a "megalock.dll" file?
But the way one week trying to boot in system after flashing KDZ files with UPPERCUT and after many and many bootloop I finally enter the system with H85020a_00_OPEN_EU_OP_1030.kdz
But after one reboot it returns the problem.
I am desperate.
Have you got a phone name to buy that is unbrickable?
There are a number of generic installation guides for custom roms eg https://www.xda-developers.com/how-to-install-custom-rom-android/
However this one is specifically for the LG G6 and tested using the US997 model. It worked for me, but I welcome comments on how to improve it.
Create a folder on the PC for all the downloads and files
Download phone driver from LG website
https://www.lg.com/us/support/help-library/lg-mobile-drivers-and-software-CT10000027-20150179827560
Download ADB/Fastboot https://developer.android.com/studio/releases/platform-tools (You need to unzip once downloaded)
(I had an error "adb server version (31) doesn't match this client (41) killing". I searched my PC and found an older version which I had used for another phone and deleted the folders and reinstalled from the download)
Ensure the phone is backing up. (Google backup is working, you have all your photos music etc downloaded) the next steps will wipe the phone
Remove the PIN/Password/Fingerprints from the phone so it will boot without any security.
Unlock the bootloader
https://developer.lge.com/resource/mobile/RetrieveBootloader.dev
The phone will then reboot and do a complete wipe so you need to wait a while for Android to setup.
Telegraph has the latest news on LG G6 ROMs and Recovery. From here I got the links for SHRP recovery which seems more up to date for LG G6 than TWRP. (https://web.telegram.org/#/[email protected])
https://sourceforge.net/projects/pa-g6/files/Releases/SHRP/20.07.2020/US997/
I named the downloaded file "recovery" (You need the .img file not the ZIP)
There are lots of active ROMS for LG G6 I have Lineage installed on another phone which works really well, but Havoc seems the most popular on the G6.
Download the ROM and Gapps https://opengapps.org/ (I used Nano, remember G6 is 64bit)
You will also need to update the bootloader. This was the latest I found for the US997
https://androidfilehost.com/?fid=1899786940962575226
(I missed the bootloader the first time and Gapps will not flash, I was helped by the LG G6 community on Telegram https://web.telegram.org/#/[email protected])
Now you have downloaded all you need
Then connect the phone to the PC and ensured you have ADB debug on in developer options and boot the phone into fastboot
On the PC open a command prompt in the folder you have all the files:
adb reboot bootloader
To load the recovery to the phone :
Fastboot flash recovery recovery.img
YOU MUST NOW BOOT DIRECTLY TO RECOVERY. Do not reboot to Android as this will automatically reset recovery to the stock version.
Unplug the USB cable and reboot to recovery (hold volume down + power button).. continue holding until phone reboots...
As soon as you see the LG logo on the screen.. let go of the power button then quickly press it again (never letting go of volume down).
Keep holding until you see the Factory Reset screen. Click thru the factory reset screens using the volume buttons to move up/down and power button to select. Choose "Yes" twice (saying you want to reset the phone it should boot into your new recovery. Despite what the screen says it won't actually factory reset/wipe your data... as long as you've installed a custom recovery and have not booted into Android since then.
Most likely you will be asked the password to decrypt the data folder. I tried my phone PIN and other default passwords suggested on the internet. I eventually found that this is a known issue and you need for cancel out of this screen and go and "FORMAT DATA"
Reboot directly to recovery (select reboot recovery in Skyhawk), this time you should not be asked for the decryption password.
I recommend you backup your current setup before making changes. If you hit issues you can use the recovery to restore. My SD card slot is broken (Poor LG design) so I plugged a USB thumb drive into the USB C slot and did a full backup. (No data since I just formatted it).
Wipe the partitions before you flash
Full wipe ("The only option you ever need")
Select Advanced and wipe system partition.
FLASH (You need to put the ZIP files either on the USB drive as I did, or copy to your SD card, or you can use ADB sideloader from the PC to push the files to the phone). The USB drive seems the easiest since you can plug it into your PC to load the files then plug it into the phone to read them.
Flash in the following order
Bootloader
ROM
Gapps
After Installing wipe cache and Davik
Reboot
It will do lots of processing while setting up. Ensure it stays cool (remove case and leave it plugged in with the screen off)
Donate to the developer of your new ROM at the end when it works.
I have been running my LG G6 on Android 10 for a few weeks and thought I would share my observations, I am using Havoc 3.7 installed with Skyhawk, I did not root the phone.
Likes : Very smooth experience, phone feel like it is running much faster. Very stable, I had one surprise reboot in the time I have used it. No issues (so far) with installing or using any apps including banking. Much lower use of storage, I have 6GB free.
Same : Battery life is about the same as before.
Gaps : Cannot encrypt, VOLTE doesn't work (which may become a big issue for T-Mobile and AT&T soon), when being used the phone gets much warmer than it did before and the wifi setting randomly turns off.
Next Steps: I am going to try Lineage which has released some fixes for the WIFI issue and report back.
I'm trying to follow the instructions as per this guide for the tmo version of G6 (H87220g) and I'm running into a roadblock on the recovery flash:
[[email protected] tmp]$ mkdir skyhawk
[[email protected] tmp]$ cd skyhawk && 7z x ../SHRP_v2.3.2_us997-233920072020.zip
[[email protected] skyhawk]$ fastboot flash recovery recovery.img
Sending 'recovery' (36936 KB) OKAY [ 1.252s]
Writing 'recovery' FAILED (remote: 'unknown command')
fastboot: error: Command failed
Click to expand...
Click to collapse
I downloaded the Skyhawk zip from the PA download link, unzipped it and used the recovery.img file found inside the zip as part of the fastboot command. Is this incorrect ?
Yes, you need the recovery.img file to flash via fastboot. Have you successfully unlocked the boot loader? You cannot replace recovery without unlocking.
You also need to ensure you have the appropriate files for your phone I have a US997 but as you have H872 you would need skyhawk for the H872 in the notes above you are still using US997.
bootloader is unlocked as per:
https://forum.xda-developers.com/tmobile-g6/how-to/unlock-bootloader-tmo-t3578099
fastboot flash is failing and I'm not the only one it seems like based on comments here and reddit...
I gonna try out @runningnak3d guide and see if that works...
This guide is for the US997. The H872 has a much more complicated process to install recovery : https://forum.xda-developers.com/tmobile-g6/how-to/root-h872-to-including-11g-t3775518
Hi All,
With the recent launch of LineageOS 18.1 I decided to take the plunge and get it installed on my fully stock Videotron/Freedom H915. Since I had to smash together info from a half dozen other threads, I figured I'd gather it all together here for folks with a Canadian phone trying to make this work.
Since I knew absolutely nothing coming into this, I'm going to go a little more detailed on this write-up. If you've been flashing ROMs since the old days of Cyanogenmod you can probably skim half of this.
Disclaimer : I'm not responsible for any bricked phones or other negative outcomes. This is what worked for me, but I'm far from being an expert. If you continue past this point you agree to take your time, do your reading, be responsible for your own device/actions and not hold me or the forum accountable for anything that might go wrong. You've been warned.
IMPORTANT NOTE #1
If you've picked up an H915 on ebay and you are intending to use it on a network other than the one it's SIM locked on, make sure you do the whole SIM unlock process on the stock ROM either before you get started at all, or once you've reverted to the vulnerable stock ROM after Step 1 below.
I actually use Telus as my provider and I wasted a bunch of time trying to figure out why I couldn't get signal because only the stock ROM will prompt you for a SIM Unlock code. Lineage will just sit there dumbly and not allow you to enable data.
Once you've unlocked the SIM it will stay unlocked from that point forward, just make sure to unlock it and verify your SIM is working with LTE on the stock ROM before you get started.
IMPORTANT NOTE #2
Use LGUP's "DUMP" feature to take a backup of ALL partitions on your phone before you start. If you're reading this thinking "I just bought this phone off ebay, there's nothing on it I care about", take the backup anyway. You never know when you might need a copy of the modem partitions or other things from your phone's original build. It came in super handy for me in troubleshooting the process. So go do a backup!
Current Issues:
If signal is too weak to connect to a tower (or non-existent), the OS tends to crash with a modem error. Still trying to figure this one out.
I think I can get this working without first jumping to US996 but haven't had a chance to verify that. If I do I'll update the thread.

Different Boot Modes
For those not familiar with these phones, there are three different "modes" the phone can boot into. Here's a quick reference on how to boot into each one.
Download Mode
This mode is used for pushing KDZ files or individual partition backups using LGUP
Turn Off Phone
Hold the Up-Volume Button
Insert USB-C Cable with other end already plugged into PC
Bootloader (aka Fastboot) Mode
The H915 doesn't come with this mode by default. If you try it, you'll just get battery charging. We'll be temporarily converting the phone to a US996 in order to use the DirtySanta exploit to replace the bootloader partition with a leaked Engineering aboot.
This mode is used with the fastboot tool to load the TWRP utility into the Recovery partition.
Turn Off Phone
Hold the Down-Volume Button
Insert USB-C Cable with other end already plugged into PC
Recovery Mode
The recovery mode on a stock phone is used to perform a factory reset. We will be using the Factory Reset a couple times with the stock ROMs, then replacing the contents of the recovery partition with the TWRP tool that allows us to format partitions, load partition images, and sideload apps and LineageOS itself.
Turn Off Phone
Hold the Down-Volume Button
Press and hold Power-On (rear fingerprint sensor/button). When LG Logo appears, release power button for 1 second then press and hold again
When "Factory Data Reset" appears, release all buttons
Press Volume Down to highlight "Yes" then press power button to select the option
Repeat for the confirmation
Note about flashing KDZ files using LGUP
You can flash KDZ files onto the phone using LGUP from two places - either with the phone in "Download Mode", or with the phone booted into the OS with the USB Options set to "File Transfer" and USB Debugging turned on.
The difference between these two is when it performs the OS compatibility check.
In Download Mode it's the code of the Download Mode partition that does the check. In the OS, it's the OS that does the check before booting to Download Mode and bypassing Download Mode's check.
Why is this important? Because when converting from one phone to another (Say, an H915 to a US996 like we do below), you initially can't flash the KDZ using LGUP's "Upgrade" function. You can only use "Partition DL" to replace the contents of partitions with the contents of the KDZ. This kind of works, but ends up with a phone that will sometimes identify as a H915 (in Download Mode) but sometimes identify as a US996 (in the OS). To clean it up, once you've done the Partition DL method, you can do it again from the OS and use the Upgrade method to get a really clean install.
It works going back the other way as well when you want to return to stock.
If this doesn't make sense, don't worry. You don't need to fully understand it to follow the instructions below, I just found it to be interesting info that didn't seem to appear in other threads.
Process Overview
Revert the phone to an old/vulnerable stock Nougat ROM for Videotron/Freedom Mobile
Enable Dev Options
Dump contents of US996 KDZ partitions over top of existing partitions
Cleanup by re-flashing US996 KDZ partitions over top of existing partitions
Transfer files to the SDCard and install Terminal Emulator
Unlock the Bootloader using the DirtySanta exploit
Boot to old TWRP and install new TWRP
Boot to new TWRP, install LineageOS, Google Apps, and flash modem partition image
Reboot to LineageOS
Actual Process
1 - Revert the phone to an old/vulnerable stock Nougat ROM for Videotron/Freedom Mobile
We need to be on Nougat for this to work, so if you're on Oreo you have to downgrade to Nougat before we begin. I chose a Nougat ROM for the H915 that's vulnerable to the DirtySanta exploit because I know it works and because I'm hoping in the future to be able to skip converting the phone to a US996 if possible.
Boot phone into Download Mode
Launch LGUP with Patch
Select "Upgrade" radio button
Select bin file : H91510e_00_VTR_CA_OP_1205.kdz
Click Start
When finished phone will reboot
1.5 - Do this if Step 1 Failed... Otherwise continue to Step 2
Depending on what's loaded on your phone when you start, it might complain about doing Step 1. This should allow us to bypass the issue and allow Step 1 to work. You can use this step if you've already converted the phone to another model as long as it's not bricked.
Boot phone into download mode
Launch LGIP with Patch
Select "PartitionDL" radio button
Select bin file : H91510e_00_VTR_CA_OP_1205.kdz
Click Start
Click the "Select All" partitions checkbox and click OK. When done it will reboot.
If it hangs or loops on reboot, boot into "Recovery Mode" (which at this point will Factory Reset the OS)
The phone boots into the OS
Quickly go through setup wizard. Skip as many things as possible.
Go Settings - General - About Phone - Software Info - Make sure it identifies as H91510e
Change the USB Option mode to "File Transfer"
Then repeat Step 1, but from inside the OS instead of in Download Mode
2 - Enable Dev Options and File Transfer Mode
We need these enabled after every time we flash the OS so that our LGUP and adb commands will work. You'll get used to doing these steps a bunch.
Quickly go through setup wizard. Skip as many things as possible.
Unplug USB-C cable
Swipe down from the top and change from USB Charging mode to File Transfer mode
Settings - General - About Phone - Software Info
Tap on Build Number many times until it unlocks Developer Mode
Go back 2 menus and enter the new "Developer Options" menus
Make sure "Enable OEM Unlock" is enabled
Enable "USB Debugging" (will be greyed out if USB-C cable is still attached)
Go back to main screen
Plug USB-C cable back in.
A pop-up will appear asking to Allow USB Debugging. Check the "Always Allow" box and tap OK
3 - Dump contents of US996 KDZ partitions over top of existing partition
The Videotron/Freedom KDZ has no Bootloader/Fastboot mode. If you try to enter bootloader mode you'll just end up charging the battery. So we have to cross-flash the US996 KDZ to get a phone with a bootloader which we can then replace with the engineering version using the DirtySanta exploit.
Boot phone into download mode
Launch LGUP with Patch
Select "PartitionDL" radio button
Select bin file : US99610f_00_1205.kdz
Click Start
Click the "Select All" partitions checkbox and click OK
When the phone boots back into the OS, repeat all of Step 2.
Note: If it asks for a password on startup, follow the "Boot to Recovery" steps and since
we don't have anything loaded in the recovery partition it will wipe/erase the phone
and remove the password.
4 - Cleanup by re-flashing US996 KDZ partitions over top of existing partitions
As mentioned in the "Note about flashing KDZ files using LGUP" section above, after you use the PartitionDL method you get a kind of dirty phone image that doesn't always identify as its new model. To clean up, we repeat the process in Upgrade Mode, taking advantage of the fact that at least the OS now identifies as US996 even if Download Mode doesn't. After this, Download Mode will also identify as US996.
Starting booted into the OS with a USB-C cable attached (File Transfer mode, USB Debugging on):
Launch LGUP with Patch
Select "Upgrade" radio button
Select bin file : US99610f_00_1205.kdz
Click Start
When the phone boots back into the OS, repeat all of Step 2.
5 - Transfer files to the SDCard and install Terminal Emulator
We will need some files on the SDCard in the phone in order to install them, either inside the OS (in the case of Terminal Emulator), or later on from TWRP. The Terminal Emulator will be used for the DirtySanta exploit so we need to get that installed now.
Make sure the USB Connection is set to Data Transfer mode and copy the following files to the SDCard:
APK for Terminal Emulator
twrp-3.5.1_9-0-us996.img
h915freedommobilemodem.img
Enable installing apps from unknown sources by:
Settings - General - Fingerprints and Security - Unknown sources (turn it On)
Install Terminal Emulator:
Tools - File Manager
Choose "Allow" when prompted
Click the up-arrow next to "Internal Storage"
Choose SD Card
Scroll down and tap on jackpal.androidterm-1.0.70-71-minAPI4.apk
Install
6 - Unlock the Bootloader using the DirtySanta exploit
The US996 KDZ has a bootloader but it's locked. In order to unlock it we need to use the DirtySanta exploit to give us permissions to replace the Bootloader/Fastboot with a leaked engineering version.
Starting booted into the OS with a USB-C cable attached (File Transfer mode, USB Debugging on):
Settings - General - About Phone - Software Info
Verify that Software Version lists as US99610f
Copy the twrp-3.0.2-1-us996.img file into the folder containing the LG V20 Root Package
Open a command prompt window and change to the folder containing the LG V20 Root Package and run "Step1.bat"
It will push multiple files to the phone and apply some patches/exploits.
This proces will take 5 minutes and put you out at an "elsa:/ $" prompt
At this "elsa:/ $" prompt in your command prompt window type the following:
run-as con
chmod 0777 /storage/emulated/0/*
On the phone, launch Terminal Emulator and run the following:
id
Verify that the string which comes back contains the string "context-u:r:untrusted_app".
If not, run Step1.bat again, else continue forward
Enter the follosing command into Terminal Emulator (be very careful to type it properly):
applypatch /system/bin/atd /storage/emulated/0/dirtysanta
If that command came back with an error, close and re-open Terminal Emulator and try again
The command should begin to patch another file. This will take 5 minutes and will return you to the "elsa:/ $" prompt in Terminal Emulator when it has finished
Open another command prompt to the same folder and run "Step2.bat"
This step will download backup copies of the boot and aboot partitions from the phone then boot the phone into bootloader/fastboot mode.
You'll know it worked if the first line at the top of the phone screen appears in red
In the command prompt window, run Step3.bat
It will flash boot1.img and the TWRP Recovery image multiple times then restart the phone
The phone will hang, no matter how long it's left. Wait 5 minutes (at least until the logo re-loads once) then do the following:
Unplug the USB-C cable
Remove the battery from the phone to turn it off
Replace the battery
Boot into Fastboot mode and run the following commands in your command prompt:
fastboot flash boot bootbackup.img
Remove the USB-C cable and battery to turn off the phone. Then replace the battery and enter Recovery Mode
The phone will show a big red exclamation mark saying "Your device is corrupt". This is normal. It will go away after a few seconds then boot into recovery. This error screen is the result of the engineering "aboot" image that was flashed to give us an unlocked bootloader and will always happen on boot.
7 - Boot to old TWRP and install new TWRP
The old version of TWRP recovery will load. Don't ask me why we can't just go straight to new TWRP above, it didn't work well when I tried it.
If it asks for a password to decrypt data, click Cancel
Swipe to allow modifications
Install - Select Storage - MicroSD Card - OK
Install Image - Scroll down and tap the "twrp-3.5.1_9-0-us996.img"
Select the Recovery partition and swipe to confirm flash
Back to main menu
Reboot - Recovery
8 - Boot to new TWRP, install LineageOS, Google Apps, and flash modem partition image
The new version of TWRP will load:
Check the "Never show this screen during boot again" box
Swipe to allow modifications
Wipe - Format Data - type "yes" to continue
This is likely to fail the first time. Repeat it to properly format the data partition.
Go back to Main Menu - Wipe - Advanced Wipe - Select "Dalvik / ART Cache", "System", and "Cache"
Swipe to wipe
Back to main menu
Advanced - ADB Sideload
Plug in USB-C cable
Swipe to start sideload
In command prompt window on PC type the following:
adb sideload lineage-18.1-20210506-nightly-h910-signed.zip
When complete tap "back" and "ADB Sideload" and swipe again to apply another file:
adb sideload MindTheGapps-11.0.0-arm64-20210412_124247.zip
If you want to root the phone (completely optional, not necessary for this process), now is the time to do it. Tap "back" and "ADB Sideload" and swipe again to apply another file:
adb sideload Magisk-v23.zip
Go back to main menu - Install - Install Image - tap the h915freedommobilemodem.img file
Select the Modem partition and swipe to confirm flash
Remove USB-C cable
9. Reboot to LineageOS
Go back to main menu - Reboot - System - Swipe to reboot

thank you so much. i need it
Great job for writing a complete how-to guide!
Thank You, You saved my old V20 H915
hi have you been able to find a better modem?
btw i'm not able to decrypt under twrp, can you?
Just want to confirm, it's only guide wich works for me. But I have issues with modem:
1. When I tried to change mode of modem, "prefered network type", phone stayed in the loop of the kernel panic "modem crash"
2. It were difficult to revert changes back. Finally, safe mode (in order to get it, you need to press volume up and volume down in the same time, during LinageOS booting process) helped me - when I disabled airplan mode, I had 2-10 seconds until next kernel panic. And in ~10 attempts, I were able to finally switch modem's mode to GSM/WDCMA/LTE
3. I used this phone 3 days, and once the kernel panic (because of modem) happened again
Any ideas what to do with modem? Also, the picture "Your phone is corrupt" is not fan Any ideas how to change it?
I did my best to follow all the instructions but after step 7's reboot I just get blocks full of static. I can tell it's trying to do fresh install setup though from what's peeking through the blocks.

This is normal. Flash a kernel that's patched for dirty santa OR, cover the proximity sensor on boot and keep it covered until boot is complete.
That worked, thanks.
After multiple attempts going back and forth with step 6, I finally did it! I might switch to Lighthouse or Arros but I wouldn't have gotten this far without your guide.
Hello everyone..
I just got hands on LG V30+ carrier device from ntt docomo model number to be exact L-01K It's network unlocked and using adb debloat i have managed to get rid of almost docomo japan apps.
But i am stuck on android 9 pie. I tried to unlock bootloader official way but my device doesn't go for fastboot. I was wondering someone had this device and whether if it's possible to unlock and flash custom recovery..thank you
before you flash anything to your L-01k you need to backup the modem partitions with LG UP.

If you have no backup of the modem, you will lose network and there's no firmware for the L-01k anywhere on the net to restore... ask me how I know..

Here is elf file if you dont have. You can go to qualcomm mode by plugging in usb cable in mobile and press volume - and power button and when black screen show keep pressing volume +. you also need to install qualcomm drivers to detect mobile in windows.
Thanks a lot for the files and advice! Will try to restore the modem now..
dont restore ftm i mentioned it by mistake.
I can't figure out how to flash the files back using QFIL. I was in download mode volup then connect USB, same as you do it with LGUP). But that didn't work. QFIL says "Download Failed switch to Emergency Download Mode".
I also tried flashing the modem.bin with TWRP (backup in TWRP, then replace modem.emmc.win with modem.bin and rename that accordingly, then restore backup in TWRP. But that did not work (SIM Card not recognized and no IMEI). Then I flashed back the original modem.emmc.win backup to fix sim card and IMEI.
I think I am missing the XML file for QFIL?
first install qualcomm drivers.
plug usb cable to pc and mobile. hold volume down and power button at same time and when black screen show on mobile keep pressing (don't hold) volume up without leaving other buttons.
when qualcomm mode is detected > run qfil and select port and than > select flat build and > elf file in programmer path and > select ufs storage type in bottom right.
then go to tools > partition manager and there you can find all the partitions first backup and than restore which i said before.
these backups will not work in twrp i think.
don't mix this with download mode in which we can go with just volume up and put cable in pc. if you don't know please google it first its qualcomm mode.
if you have fastboot try this command in fastboot:
fastboot reboot edl
if that works than just follow other steps. to quit this mode press volume down and power button for few seconds. in this mode screen just stay black and nothing will display on your screen.
OK found a youtube video on how to get into EDL 9008 mode:
- Connect the smartphone via USB to the computer.
- On the switched-on smartphone, hold VOL- and POWER
- As soon as the screen turns off, keep holding the VOL- and POWER buttons and simultaneously press VOL + quickly.
- The smartphone will have a black screen, and in the device manager on the PC will be "QUSB_BULK_CID: xxxx_SN: xxxxxxxx" or "Qualcomm HS-USB QDLoader 9008 (COM x)
OK, that worked for me (windows device manager reported "Qualcomm HS-USB QDLoader 9008) , but when I wanted to use the partition manager in QFIL i get the "Download Fail Sahara QSaharaServer Fail: Process Fail "
I'll try this now:
-downgrade to Nougat H930 KDZ ( H93010v_00_OPEN_EU_OP_1120.kdz)
in fastboot: (Using the modem.bin, modemst1.bin, modemst2.bin from L-01k QFIL dump)
fastboot erase modem (enter)
fastboot erase modemst1 (enter)
fastboot erase modemst2 (enter)
fastboot oem lock (enter)
fastboot flash modem modem.bin (enter)
fastboot flash modem modemst1.bin (enter)
fastboot flash modem modemst2.bin (enter)
EDIT: it didn't work
But at least I know now how to get into Download Mode from a Bootloop:
1. Connect USB to PC
2. press Vol+, Vol-, Power until the phone restarts with black screen
3. immediately release Vol- and Power and keep pressing Vol+
.. voila.. Download mode
did you add the v30 file in proggamer path in qfil which i provided and changed the storage type to ufs?
yes, I used that firehose V30 file and I verified that storage is set to UFS.
have you fixed it?
nope, but after flashing the modem with ADB and also trying the V300k Korean ROM, I have learned how to fix a near bricked V30 by using 9008 Qualcomm unbrick mode back to life .
I think the only way to fix this is if a L-01k KDZ is released or someone manages to root his L-01k without overwriting the modem and uploads his complete TWRP backup.
Thanks guys for ur help. It seems like no bootloader unlock for my LG L-01K. So modem backup didn't work. I'm so sorry to hear that. I wish i had rooted my device. But i can't even unlock the bootloader. I want to try custom roms so badly. I guess i have to stuck with android pie. Thanks again.

do you have wifi working and your imei is not null?
wifi works, IMEI exists, says Sim card 1 is "PERM locked".
I'm on H93020d_00_OPEN_EU_OP_0326.kdz now.
The same Sim card works perfectly in my LG G8s

Debloat Japanese Apps like Docomo Contacts App from L01K V30+ ?
How did you do that using ADB ?
With or w/o Root ?
Can you or anyone explain ?
