{GUIDE} {H918} Restore laf partition/Download mode after root with lafsploit.

{GUIDE} {H918} Restore laf partition/Download mode after root with lafsploit. - LG V20 Guides, News, & Discussion

As the title states this guide will walk you through restoring your laf partition/download mode after root via the lafsploit method.
This guide is for the H918/T-Mobile variant ONLY!
Attempting to use the files provided in this thread on any other variant may result in a brick! You have been warned.
YOU MUST HAVE SOME FORM OF ROOT ACCESS FOR THIS PROCESS TO WORK!
Before we begin this guide will be relatively straight forward, and much easier than rooting the phone itself (IMO). That said when making any modifications to your device, and by following this guide you assume any & all responsibility for any damage physical or otherwise to your device(s).
Prerequisites/Downloads:
1. ADB & Fastboot drivers Download & install (If you don't already have them of course) from here: https://forum.xda-developers.com/showthread.php?t=2588979
(There are other ways to obtain them, but this is the simplest and most straight forward.)
2. I'm not entirely sure they are needed for this, but it wouldn't hurt to install the LG Mobile Drivers either found here: http://www.lg.com/us/support/software-firmware-drivers
3.I have extracted (from 10P KDZ) and tested this image myself before uploading, and now have download mode back on my v20. You can find it here: https://www.androidfilehost.com/?fid=818222786056038567 (Save to a location you can remember. If you're unsure go ahead and save it to your desktop.)
These remaining downloads are entirely optional, but I figured I would include them. Only download these if you intend to extract the laf.img yourself. (More details on that later.) (Not recommended for the average user.)
1. You'll need the kdz to extract the images from. Found here: https://lg-firmwares.com/lg-h918tn-firmwares/#more-3864 (You're looking for the H91810p kdz).
2.You'll also need to download the WindowsLGFirmwareExtractor found here: https://forum.xda-developers.com/showthread.php?t=2600575 (Be sure to leave a thanks for this awesome tool.)
Flashing the image
1. Begin by verifying USB debugging is enabled on your device. (If it is not go to Settings/About/Software Info. Click build number until you get the toast notification that you are a developer. Back out to Settings Click Developer Options, and turn on USB debugging.)
2. Plug in your device (Make sure it is in File transfer mode.)
3. Open up a command prompt (May require running as admin. I always do so I have no clue.)
Type:
Code:
adb devices
Your device should be listed if you have accepted the prompt on your device. (If you are not quick enough and accept the prompt, but it still shows nothing run adb devices again.)
4. If your device is listed navigate to where you saved the laf.img (again for the purposes of this guide I will be using the Desktop.)
Type:
Code:
cd c:/users/Type your windows username here/Desktop
You should now be in your desktop.
Type:
Code:
adb push -p laf.img /sdcard/laf.img
wait for it to complete.
Type:
Code:
adb shell
then
Code:
su
You will need to grant adb Superuser permissions on your device to continue. If you are successful you should see this "elsa:/ #"
Finally type:
Code:
dd if=/sdcard/laf.img of=/dev/block/bootdevice/by-name/laf
Wait for it to complete.
Type exit twice.
5. You can now unplug your device, power off, and plug in the usb while holding vol up to enter dl mode to verify it worked.
6. Success Congrats. You have download mode back on your device!
Extracting the laf image yourself(For the extremely paranoid)
1. Download the required files from above.
2. Extract WindowsLGFirmwareExtract v1.2.5.0 to your desktop, and open it up (preferably in it's own folder).
3.Select Open across from KDZ/TOT file, and browse to your KDZ you download previously and double click.
4.After it loads the kdz check H91810p00.dz, and click Extract KDZ.
5.Close and re open the program this time Click open across from DZ File in the folder where you placed WindowsLGFirmwareExtract you should see a file called H91810p00.dz Double click to open it.
6.Check laf_6.bin then click Extract DZ.
7.Rename the laf_6.bin to laf.img.
8.Follow the steps above to flash the newly extracted image to your device.

I've had my h918 arb1 10u rooted for a month now, never noticed in twrp till now of an all in red "The partition cannot be located by the name "LAF".
Do I really need it?. I was coming from RR rom 8.0 back to Super rom 7.0 in twrp. While installing Super rom thats where I noticed the red worded statement in the list of rom install load. I was kinda startle cuz it's laf... I was like ahhh fkkk I'm gonna get bricked but then phone boots like normal, everything is normal, I even install other roms back n fourth just to test for anything else wrong but nope everything is good. I can still enter download mode with USB cord.. it acts normal, I can boot to twrp recovery normally from trwp app in stock super rom and advance menu on aosp roms too. So.... Is laf any important anymore?? Should I go ahead and and follow this guide for laf repair?....
(Edit)
Nevermind, Sorry.
I found that laf after rooting is not needed anymore cuz twrp occupies that spot. I did find a flashable laf restore zip in the thread by "[ROOT] - lafsploit - H918 (any version up to 10u) - now n00b friendly by runningnak3d".
Problem solved.

download link broken

Wanted to thank you this worked perfectly! I was in quite the predicament where I ran the LAF exploit in FWUL but I didn't downgrade before rooting. That made it so I couldn't flash TWRP to recovery and for whatever reason I couldn't boot into TWRP from download mode again (only worked once or twice) I couldn't flash in fastboot and I was sure I was screwed. THANK YOU!!!

dl link is broken, pls reup !
thx

CYANOGEN - From Box till the new ROM - ALL steps in ONE post

Even being a Linux user for 3 years I had difficulties flashing (herer the Cyanogen) Image. I didn't find all of the steps into one post, so I aggregate them for the completely "idiot" here:
1) Have an SD-card (FAT32 or ext3) inside the phone. .ZIP or .IMG files will be put there to be installed on the phone.
On the phone TURN ON: Settings>Applications>Development>USB Debugging
2) Find your Magic Version (32A or 32B, most probably 32A). Answer Number 1.1 at wiki.xda-developers.com/index.php?pagename=HTC_Sapphire_Hacking
3) DOWNLOAD ANDROID Programs:
a) Android-SDK from developer.android.com/sdk/index.html and unzip. Later you will work inside the folder tools or put the app. adb into the PATH
b) Fastboot from android-dls.com/wiki/index.php?title=Fastboot, unzip and move the program into the folder tools or put it into the PATH
4) Gain ROOT access to your Phone's OS from android-dls.com/wiki/index.php?title=Magic_Rooting
NOTE: Follow Method 2.
5) INSTALL Amon_RA's Recovery Image (its the Best) from forum.xda-developers.com/showthread.php?t=530492
SUGGESTION: Use 'via adb' method, that is:
Having the the phone normally started, plugin the USB.
From the turn on USB and copy the recovery_XXX.img file to the SdCard.
On a PC-shell give:
sudo adb shell
#flash_image recovery /sdcard/recovery_XXX.img
#exit
6) Reboot into that recovery image and keep a NANDROID backup.
a) Close the phone.
b) Hold HOME+POWER-ON buttons together for a few seconds. Wait until the menu shows up.
c) Go to backup option and make it. The backup will be automatically saved on the SD card.
d) Reboot normally and save the nandroid Backup folder from Sdcard to your PC.
7) INSTALL (aka Flash) the ROM.
For the Cyanogen MOD download the LATEST version of 3 .ZIP files from forum.xda-developers.com/showthread.php?t=592377
a) HTC Android 1.6 base image (named DRC83_base_defanged or the like)
b) an update _XXX.ZIP file
c) a "kernel port" (name something like bc-XXX_signed.zip)
Beware all the files have the same version!
Then follow the easy and simple steps noted in forum.xda-developers.com/showthread.php?t=568032
It took me an afternoon to collect all this info that is scattered here in there in the forum.
Thank you all!

Except that you cannot flash the recovery via that method if your current rom is stock (no root).

You are correct! I edited my post. I had made myself this step but I thought root access would be covered using RA's Recovery. There are so many little steps and nowhere are explained all in one place. Thanx...

I see no reason to call these people IDIOTS. That's such a shame.

If you're going to make this guide for idiots, why don't you make it say what the guide is actually for?

The expression was not meant like that. It included me and intended to separate the newbies that can easily browse to the forum and gather this scattered info from those that cannot have such ability and wished all these steps are logged into ONE post. Again, never meant in "that" way.

Why dont you just suggest applying the recovery through flashrec instead of complicating it by separating it into 2 steps.
EDIT: Plus, the rooting method is NOT the same for all phones...

I think this is a good idea, but everyone should chime in so that we can have a method for every Magic

[GUIDE][STEPbySTEP] Root/unroot BLU Pure XL (and clones)

Totally new guide! Simple step by step toutorial
It took us a while to get root on our devices. Hopefully we did it! Now we can enjoy benefits of having rooted device (like Xposed Modules etc). We have working TWRP recovery which allows us to backup your phone, flash SuperSU binaries, mods and custom ROMs (actually we are working on it). First: read whole post, then download necessary files and read it again. This guide will allow you to root your BLU Pure XL/Allview X2 Soul Xtreme/Gionee Elife E8/Condor Allure A100 and other clones I don't know.
If you don't know what is 'root' & TWRP nor understand the whole idea of rooting your phone this post (or even most of the XDA community) is not for you! Read everything carefully.

I don't know where are you wrong...!
Maybe you say something else? Maybe give me some logcat?
I would help you if I knew the problem. As for now for me you don't have any problem. Your post is useless in this form.
You have to learn how to tell the error/problem/bug before you post anything on any forum.
If you want me to help you solving this situation send me private message or edit your post and tell the problem in the right form*, please.
Cheers,
bemolx
*Right form looks like:
What's the problem?
Did you check whole thread before posting?
If possible give me logcat/shown error
Make sure you read main post carefully
What you will need to get it working:
ADB and Fastboot drivers
SuperSU flashable zip archive
TWRP Recovery image
PC & your phone
BUT!
Code:
Your warranty is now void.
Everything you're doing with your devices is on your own!
We're not responsible for any damage on your phone!
If you don't understand what's root it's good time to STOP!
Now we're starting!
Look carefully on files you need (I've mentioned them above) and scroll down for download links. Download every file we need.
Note:
At the bottom of this post you'll find two versions of TWRP: 3.1.0-x and 2.8.6.0. Let me explain the difference:
TWRP v3.1.0-x: this version has been compiled from scratch & made by me. It is the newest available recovery version at the moment and without bugs. More info in the thread linked below.
TWRP v2.8.6.0: this version has been ported from Xiaomi Redmi Note 2 & made by @acheron1502. It's not the newest but working one. It has some little bugs. More info in the thread linked below.
I suggest you to download v3.1.0-x because it will get further support by me. But it is your choice now.
Setting up our workstation
I hope you have already downloaded everything we need.
On your Desktop create a new folder (for example "root").
Find package with ADB drivers, open it and extract to the "root" folder.
Now find TWRP image and place it also in our "root" folder. This image should look like this:
Code:
twrp-3.1.0-0-x2xtreme.img
or
Code:
BLU_PURE_XL_TWRP.img
Let's rename it like this (see below) to make our rooting process easier
Code:
twrp.img
Now we're setting up your phone
Open 'Settings' application. Scroll down to 'About phone'. Click about seven times on 'Build number'. You should see: "You are now developer".
Now find 'Developer options', then 'Enable USB Debugging' and simply enable it.
Connect your phone to the PC. On PC: find SuperSU.zip and copy it on your phone.
OMG!!! Flashing!!!
Okay... That's the most important step.
Turn off your phone. Press 'power' & 'vol +' together. This key combo should boot up your phone into stock recovery mode.
Scroll down using 'vol -' to 'Reboot bootloader' and confirm pressing 'power'. This will boot your phone into Fastboot mode.
On PC: open "root" folder. Open Command Prompt here (LShift + right mouse click -> 'open cmd here')
In the Command Prompt type:
Code:
fastboot flash recovery twrp.img
This command will flash TWRP recovery on you phone.
After flashing process is done reboot you phone into TWRP by pressing 'vol +' and 'power'. When you see bootlogo get your finger from the 'power' button. You will see TWRP logo. You can unplug USB cable now.
We're almost here!
Now you should see TWRP main page same like in the screenshots I've attached to this post.
We must flash SuperSU binaries to get rooted phone. To do this press 'Install' button.
You should see list of files/folders on your phone. Navigate to the SU.zip and choose it by clicking on it.
TWRP will ask you for permission to flash that zip package. To allow it to do so swipe to the right slider on the bottom of the screen. Now SuperSU is installing.
After installation process is done press 'Reboot system now' button. Your device will reboot into your system.
Done!!!
And there you go! Your device should be now rooted with TWRP recovery installed. Check if your phone is rooted correctly by installing ROOT Checker. To make rebooting process much easier and faster you can download Quick Reboot.
Xposed Modules
There's an option to install Xposed Modules as I mentioned at the top of this post. Not every module is working but you can try it and let us know what's working.
To get it working you need:
Xposed Installer Alpha App (allows you to download and manage modules)
Xposed SDK zip (the most important thing)
Original thread with those files is linked below.
Note:
It's important what version of SDK you are downloading. Our device has 64-bit ARM MediaTek chipset so it is arm64 and it's running lollipop 5.1 ROM which equals sdk22. By that meaning the SDK zip you should download looks pretty much the same like this:
Code:
xposed-v80-sdk22-arm64.zip
Installing
Place both files on your phone's storage and reboot to recovery. Press 'Install' and navigate to sdk.zip. Choose it, confirm installation - when it's done reboot into system. Now use any file browser and find XposedInstaller.apk and install it.
Now you can download any module you want. Further instructions in post linked below.
How to unroot
Most of you would like to flash stock OTA etc.
To do this you have to have stock recovery installed.
First open SuperSU app, then scroll down and look for 'Clear/unroot' option. Choose it and follow on-screen instructions.
Then download stock recovery image (downloads for Elife E8 and Allure A100 will be available when someone provide me a link). Place it the 'root' folder (or just in the same directory with fastboot drivers etc.). Rename downloaded file into recovery.img.
Method 1 - using Fastboot
Reboot phone into bootloader mode. Open terminal in the 'root' folder and type
Code:
fastboot flash recovery recovery.img
Now reboot into system by pressing power button for a while.
Method 2 - using TWRP
Copy downloaded recovery onto your phone's storage. Reboot phone into recovery mode. Press 'Install', then change from installing zips to installing imgs (bottom right button). Navigate to downloaded recovery file and choose it. Confirm installation. After that reboot into system.
You should be now unrooted and able to flash OTA.
Downloads:
ADB & Fastboot drivers: link
TWRP Recovery: TWRP v3.1.0-0 (recomended) or TWRP v2.8.6.0 (unofficial)
SuperSU binaries by @Chainfire: link
Stock recovery: Pure XL & X2 Xtreme (extract .zip before renaming/installing)
TWRP Materialised - Dark / Light / Play
Xposed Modules

Hey @bemolx ,
Since your thread is more of a HOW TO root, would it be OK if you move this into GENERAL and field all the rooting process questions there?
I will start a new Dev Thread for TWRP and all TWRP related development issues.
You can then use that new thread for all your download links.
EDIT:
Please use this link for TWRP in your guide.

My friends and me figured out how to get root on our phones. By the way @acheron1502 made TWRP recovery which allows us flash Super SU 2.46 (Stable). Also you can flash Xposed Modules as you want.
HOW TO INSTALL:
Connect phone to your PC
Make sure you have adb and fastboot drivers installed
Download TWRP from this post
Download Super SU
Copy SU.zip to your phone's storage
Reboot phone into fastboot/bootloader mode
Flash recovery using: fastboot flash "downloadedrecoveryfilename"
Reboot to TWRP by pressing and holding Vol+ & power buttons (still in fastboot mode!)
In TWRP flash SU.zip, then reboot
What doesn't work:
- no adb in recovery

And there you go! Your device should be now rooted with TWRP recovery installed. Check if your phone is rooted correctly by installing ROOT Checker.

Let's keep the development thread about this phone (Blu Pure XL) and other phones with the exact same base maker/model (ie. Gionee E8, Allview x2 Extreme). If you are asking about gaining root for a different phone and need some Mind-share from this group of people due to the other phone having a similar SOC, the best way is to open a new thread in the Q&A Section or the General Section, but I think you should wait until the phone is released first IMHO.

Guys,
1) THANKS for GREAT work!
2) Please provide more CLEAR / ACCURATE details on how to do this, because NOOBs (including myself) get very confused.
a) Link to adb / fastboot drives. Saying "they are in Google development section means nothing"
b) How do I "Reboot phone into fastboot/bootloader mode"??
This would help so many people root without bricking the phone.
Thank you once again!

I'm having issues with fastboot. It says it's blocked for security. Is there something required that isn't normally on android phones to get the fastboot method to actually allow me to enter fastboot? At the beginning was just going to recov ery and putting reboot into fastboot.

[HOWTO] Cube iWork 10 Flagship Dual boot (i15-T) - unlock, TWRP, root

WARNING: Performing the actions decribed here will void your warranty and possibly brick your device. This was not written for complete noobs and assumes some prior experience. I will not be held responsible if you ruin your device.
NOTE: This was all tested on a stock iWork 10 Flagship dual boot (aka iWork 10 Ultimate) purchased from the manufacturers website. Device model is "i15 T", Device serial number starts with "i15TD": if you have another variant such as i15TL i can not vouch for any of this working the same way.is tablet
UPDATE: @popcorn2404 modified the boot.img on his USB Type-C variant if this tablet (i15-TCL), confirmed everything working well and was nice enough to provide the modified boot image. See downloads at end of post.
OTA: Most likely this will break OTA. Dont know yet...
Prerequisites:
PC with working ADB/Fastboot
Device properly recognized.
I'm using ubuntu 15.10 so I just added an entry to /etc/udev/rules.d/51-android.rules to get things going properly
(EDIT: Windows 64 bit usb drivers attached to post -thanks @Jade.J.Munkey)
TIP: I would highly recommend extracting your stock recovery, boot and system images for safekeeping. These can easily be flashed back in fastboot if something goes wrong. Some may say this is overkill as you will be able to backup and recover with TWRP, but one never knows...
Unlocking bootloader
WARNING: this will erase all data, settings, etc... AND system default language will be chinese when you reboot
Go to settings, about tablet and tap 5 times on the Build number to activate developer options
Go to Developer options and enable OEM unlocking & USB debugging
Plug in your device while booted into android, then open a terminal
just to make sure adb is good type
Code:
adb devices
my output looks like this
Code:
List of devices attached
0123456789ABCDEF device
reboot tablet into fastboot mode
Code:
adb reboot fastboot
The device will now reboot to the OS selection screen. Select android and then it will boot into fastboot mode
once again just to be sure all is good type
Code:
fastboot devices
once again, my output
Code:
0123456789ABCDEF fastboot
then to unlock the bootloader
Code:
fastboot oem unlock
you then should see something like:
Code:
...
(bootloader) Unlock protection is set
(bootloader) Unlocking anyway since this is not a User build
OKAY [ 15.330s]
finished. total time: 15.330s
This is what you should see now in the bootloader if all went well:
SECURE BOOT - DISABLED
LOCK STATE - unlocked
Your bootloader in now unlocked. When you reboot it will take some time for the first boot and the system language will have defaulted back to chinese. Not too difficult to sort if you're familar with Android settings. Otherwise just google "android change system language from chinese to english".
Tip: At this point you may want to already download/copy the supersu zip to internal storage of the tablet so you're all set up for flashing it later...
Modified boot.img
Because of built in security, if you make any changes to system the device will not boot, so you need a modified boot image.
If you have the exact same kernel version as I do you can download the provided modified boot image here. Otherwise you can look HERE for instructions on how to make your own modified boot image. Personally I used SuperR's Kitchen to unpack & repack the image and did the modifications manually with gedit.
Kernel version 3.14.37-x86_64-L1-R429 made on Wed Mar 2 18:22:46 CST 2016
-if you have that one you are good to go ahead and use the image provided here.
Boot device into fastboot connected to PC. From the directory where you have the modified boot image type:
Code:
fastboot flash boot i15TDboot.img
Obviously if you made your own boot image you'll need to replace "i15TDboot.img" with the name of yours...
That's it, now on to recovery and rooting...
Flashing custom TWRP (compiled by @vampirefo)
Assuming you are still connected to the device in fastboot and the custom recovery is in the same directory:
Code:
fastboot flash recovery i15t_recovery.img
Now use volume buttons to select recovery mode and tap power button.
You should now be in TWRP. First, please be smart and make a backup!
Because this device has an unusual mount point, the supersu script will fail to properly mount system (thus failing to flash) so:
From TWRP main screen select "mount" then select system, then return to main screen
Select "install" and then the supersu zip you should already have on the tablet.
Boot system. Now there is one thing left to do:
To prevent the system from overwriting TWRP with the stock recovery on the next reboot:
With a root enabled file manager mount system r/w and navigate to /system/etc
Rename install-recovery.sh to install-recovery.sh.bak
That's it. Enjoy!

Thanks
@vampirefo - for taking the time to compile TWRP for this device, you rule man!

Thanks very much for the good work, I am successfully rooted. The only deviation from the instructions that occurred for me was that /system/etc did not appear in the TWRP file manager, fortunately the .sh did not run upon rebooting after installing the SU zip. So I just I just renamed the .sh in NextApp File Explorer with Root Add-On installed once booted in to android; I have since tested booting in to recovery and then back to android and it is working fine.
Here is the driver I found to enable the Cube iwork10 Ultimate to be seen by Windows 10 64bit whilst in fastboot:

Glad it worked out for you. Based on your experience I changed the instructions in the OP. Actually that's the exact same I did after doing this the first time but I thought it would be easier to do before first boot in TWRP. Anyhow thanks for pointing this out.
Attached windows usb driver to OP. Thanks!

Can someone please make like a video for this or something more lames terms (user friendly). Cause i have a cube iwork 10 Ultimate Dual Boot (i15-TL) and am having issues on Android side where i do not have an option to move apps to sd card in apps settings. Also in storage there is no tab showing all apps on sd card. Im guessing i would need to root my device right? Can someone please help me i just want to get this working properly... i would show screenshots but i don't know how to attach them.

Will the recovery work with i15-TL?
Thank you in advance

From what I understand from reading at http://techtablets.com/forum/forums/cube/iwork-10-ultimate/
-it *should* work as my understanding is that the TD and TL are virtually identical other than different flavors of windows installed. But I can NOT personally confirm this as I have not tested on the TL variant.
What I can say with a higher level of certainty is that the procedure for unlocking the bootloader should be exactly the same. Once the bootloader is unlocked it is easy to reflash the stock recovery via fastboot should the custom recovery not work properly. (Assuming one has previously extracted an image of the original recovery to begin with. Same for boot and system images.)
So if the custom recovery does not work, it is pretty easy to reflash the original, as well as the original boot or system images should something else get messed up.
Hope this helps. Feel free to ask anything else if anything is unclear...

Thank you for your precise answer. I already successfully rooted my Cube. I need the recovery to flash the latest xposed sdk. I' ll have a look if someone extracted the original recovery.

The stock android on this device does not offer the option to move apps to sdcard.
Tools such as link2sd require a rooted device.

As clearly stated in the OP, I do not know for sure because I have not tried on that variant, but it *should* work. If you read a few posts back, you can see that another TL owner seems to have successfully rooted his device. Hot tip: *reading* is very important here before asking questions.

No, this will not affect the windows side of things. Dual boot is unaffected.

The instructions for unlocking and rooting in the OP are very simple and straightforward. If you are inexperienced in general with rooting android or with adb/fastboot, those answers can easily be found on XDA and elsewhere by searching.
As far as moving apps to SD, since nobody seems to have done it yet (or posted that they have) the only way right now would be to root your device and try out one of the specific apps for that like link2sd. I will try to check this out ASAP but can not promise how soon because I'm focusing my efforts right now on porting another ROM to this device...

Step by step guide for lg v20 h918 unlocking, downgrading, rooting and twrp

STEP BY STEP GUIDE FOR LG V20 H918 UNLOCKING BOOTLOADER, DOWNGRADING, ROOTING AND INSTALLING CUSTOM ROMS (NOOB FRIENDLY)
DISCLAIMER: I'M NOT THE DEVELOPER OF ANY OF THE BELOW SOFTWARE'S AND YOU PROCEED WITH YOUR OWN RISK AS THIS INVOLVES BRICKING OR DAMAGING YOUR MOBILE IF THE PROCEDURE IS NOT FOLLOWED CORRECTLY. I'M JUST SHARING THE WHOLE PROCESS WHICH I HAVE FOLLOWED TO ROOT AND INSTALL TWRP IN MY LGV20 H918 UNLOCKED T MOBILE.
AND I HAVE TESTED THIS IN MY OWN DEVICE AND WAS ABLE TO ROOT AND ACHIEVE TWRP.
THIS IS ONLY FOR LGV20 H918 VERSION
ENSURE INTERNET IS UP AND RUNNING IN YOUR PC
EDIT: THE WHOLE PROCESS HAS NOW BEEN AUTOMATED IN TWO SIMPLE STEPS TO PREVENT ANY POTENTIAL DAMAGE TO YOUR DEVICE. THANKS TO THE LAFSPLOIT CREATOR BRIAN @runningnak3d.
JUST FOLLOW THE PROCEDURE BELOW AND YOU SHOULD HAVE YOUR DEVICE ROOTED IN NO TIME
1. BACKUP ALL YOUR IMPORTANT DATA BEFORE PROCEEDING.
2.MAKE SURE YOU HAVE CHARGED YOUR PHONE TO AT LEAST 90 PERCENT
CHECK YOUR PHONE SOFTWARE VERSION IN SETTINGS---ABOUT PHONE----SOFTWARE INFO
IF IT IS ANYTHING BETWEEN H91810P TO H91810U MEANS IT IS ARB1 (ANTI ROLL BACK 1) AND YOU NEED TO USE LAFSPLOIT METHOD TO ROOT AND INSTALL TWRP,
IF YOUR VERSION IS H91810O OR BELOW (ARB0), YOU CAN EITHER USE DIRTYCOW OR LAFSPLOIT METHOD FOR THE SAME.
IF YOU ARE ON ARB1, PLEASE FOLLOW THE METHOD BELOW,
PART 1: DOWNGRADING
IF YOUR VERSION IS H91810 (Q, R, S, T, U) YOU NEED TO DOWNGRADE TO A LOWER VERSION ( H91810P) TO EXECUTE LAFSPLOIT.
IF YOU ARE ALREADY ON H91810P, YOU STILL NEED TO RE FLASH THE H91810P KDZ AGAIN FOR THE LAFSPLOIT SCRIPT TO WORK CORRECTLY.
DOWNLOAD H91810P KDZ FILE FROM BELOW
https://androidfilehost.com/?w=files&flid=282709
DOWNLOAD AND INSTALL ALL THE FILES BELOW IN YOUR PC
UPPERCUT AND LGUP----
http://downloads.codefi.re/autoprime/LG/Flash_Tools/LGUP/
LG DRIVERS---
http://tool.cdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425
CONNECT YOUR MOBILE TO YOUR PC IN DOWNLOAD MODE (SWITCH OFF YOUR MOBILE AND CONNECT THE USB FROM PC WHILE HOLDING THE VOLUME UP BUTTON SIMULTANEOUSLY)
RUN UPPERCUT.EXE WHICH WOULD OPEN LG'S UPDATER TOOL AUTOMATICALLY.
INSIDE THE LG UPDATER TOOL, CLICK ON BIN AND SELECT THE H91810P KDZ FILE DOWNLOADED EARLIER.
NOW SELECT UPGRADE AND FLASH
ENSURE THE USB CABLE IS CONNECTED THROUGH THE FLASHING PROCESS AND WAIT FOR YOUR PHONE TO REBOOT AND THEN REMOVE THE USB CABLE.
CHECK THE SOFTWARE VERSION AND ENSURE IT IS H91810P
PART 2: UNLOCKING BOOTLOADER
HEAD TO SETTINGS---ABOUT PHONE----SOFTWARE INFO (ENSURE IT IS H91810P)
ENABLE DEVELOPER OPTION IN YOUR PHONE BY CLICKING ON THE BUILD NUMBER MULTIPLE TIMES
NOW HEAD TO SETTINGS---DEVELOPER OPTIONS
TURN ON OEM UNLOCKING, ENABLE USB DEBUGGING AND DISABLE 'VERIFY APPS OVER USB'
NOW CONNECT YOUR PHONE TO PC AND OPEN ADB COMMAND CENTER PROMPT IN YOUR PC
adb devices---->CHECK IF YOUR MOBILE IS CORRECTLY RECOGNIZED IN ADB
adb reboot bootloader--->THIS REBOOTS YOUR DEVICE IN FASTBOOT MODE
fastboot devices---->CHECK IF YOUR MOBILE IS CORRECTLY RECOGNIZED IN FASTBOOT
fastboot oem unlock---->THIS COMMAND WOULD UNLOCK YOUR BOOTLOADER AND RESET's YOUR DEVICE.
fastboot oem device-info OR fastboot getvar unlocked ----->THIS WOULD CONFIRM IF YOUR BOOTLOADER HAS BEEN UNLOCKED OR NOT.
fastboot reboot-----> THIS WOULD REBOOT YOUR DEVICE
IF THE BOOTLOADER HAS BEEN SUCCESSFULLY UNLOCKED, THE DEVICE WILL SHOW AN UNLOCKED BOOTLOADER WARNING MESSAGE WHILE BOOTING (THIS CAN BE IGNORED OF COURSE)
PART 3: CREATING A BOOTABLE LINUX USB USING FWUL
DOWNLOAD FWUL_v2.7_x86_64_15GB.zip FROM THE LINK BELOW AND EXTRACT THE IMAGE FILE SOMEWHERE IN YOUR PC.
https://androidfilehost.com/?w=files&flid=214529
DOWNLOAD RUFUS FROM BELOW AND INSTALL
https://rufus.akeo.ie/
INSERT A PEN DRIVE IN YOUR PC AND RUN RUFUS.
INSIDE RUFUS SELECT THE IMAGE FILE AND SELECT START (AFTER SELECTING START SELECT DD MODE IN THE DIALOGUE BOX) TO CREATE A BOOTABLE PEN DRIVE (WARNING: THIS WOULD FORMAT YOUR PEN DRIVE)
NOW YOU SHOULD BOOT YOUR PC FROM THE BOOTABLE USB STICK WHICH YOU HAVE JUST CREATED
THIS WOULD MAKE YOUR PC RUN LINUX OS
TYPE PASSWORD AS linux AND ENTER
PART 4: INSTALLING TWRP AND ROOTING USING LAFSPLOIT
BEFORE PROCEEDING ENSURE YOU BOOT YOUR PHONE AND DONE ALL THE BASIC SETTINGS
NOW HEAD TO THE DEVELOPER OPTIONS IN YOUR DEVICE AND ENSURE OEM UNLOCKING AND USB DEBUGGING ARE SWITCHED ON.
NOW CONNECT YOUR DEVICE TO THE PC (RUNNING LINUX OS FROM PENDRIVE) IN DOWNLOAD MODE (SWITCH OFF YOUR MOBILE AND CONNECT THE USB FROM PC WHILE HOLDING THE VOLUME UP BUTTON SIMULTANEOUSLY)
DOUBLE CLICK ON THE LG FOLDER INSIDE FWUL DESKTOP
INSIDE THAT, DOUBLE CLICK ON LGLAF(RUNNINGNAK3D) ICON WHICH WILL OPEN A TERMINAL
ENTER THE BELOW COMMANDS
git pull
git checkout h918-miscwrte
./step1.sh
THE ABOVE COMMAND FLASHES TWRP RECOVERY ONTO YOUR DEVICE.
WAIT AND PULL OUT YOUR DEVICE WHEN IT ASKS TO.
RECOMMENDED: NOW THAT TWRP HAS SUCCESSFULLY INSTALLED, YOU CAN MANUALLY FORMAT,FLASH LATEST TWRP RECOVERY AND USE ANY METHOD LIKE MAGISK OR SU FOR ROOTING.
INSIDE TWRP RECOVERY. FIRST FORMAT USING WIPE--ADVANCED FORMAT--TYPE yes AND FULL DO A FULL FORMAT, THEN FLASH MAGISK AND THE LATEST TWRP RECOVERY BELOW.
MAGISK ZIP DOWNLOAD:
https://github.com/topjohnwu/Magisk/releases/download/v16.0/Magisk-v16.0.zip
LATEST TWRP BY PHOENIX(H918):
https://forum.xda-developers.com/v20/development/recovery-twrp-3-2-1-0-t3720239
OR
IF YOU ARE UNSURE ABOUT FORMATTING AND FLASHING, JUST USE THE BELOW COMMAND TO DO ALL THE WORK AUTOMATICALLY
CONNECT YOUR DEVICE AGAIN IN DOWNLOAD MODE AND ENTER THE FOLLOWING COMMAND
./step2.sh
THE ABOVE COMMAND FORMATS YOUR DEVICE AND FLASHES MAGISK TO ACQUIRE ROOT.
TIP : IF YOU FACE ANY ENCRYPTION ERROR AFTER USING STEP2. SH, DO A ADVANCED FORMAT WITHIN TWRP AND FLASH MAGISK AND LATEST TWRP BY PHOENIX MANUALLY.
YOU ARE NOW ROOTED WITH TWRP RECOVERY INSTALLED.
REMEMBER TO BACK UP THE CURRENT ROM BEFORE FLASHING ANYTHING..... DO CHECK POST #2 FOR OTHER TWEAKS
IF YOU WISH TO UPDATE TO LATEST STOCK (10U) AND KEEP ROOT AND TWRP, JUST FOLLOW THIS LINK AND DO REMEMBER TO ROOT USING MAGISK AFTER FLASHING THE ROM BEFORE YOU BOOT.
https://forum.xda-developers.com/v20/development/rom-h91810q-stock-rom-twrp-flashable-zip-t3681312
I WOULD LIKE TO THANK ALL THE DEVOLEPERS WHO HAVE CREATED THE ABOVE SOFTWARES WITHOUT WHICH THIS ISNT POSSIBLE.
CREDITS:
@autoprime FOR HIS UPPERCUT TOOL
@steadfasterX FOR HIS FWUL TOOL
@Phoenix591 FOR HIS WORKS ON TWRP RECOVERY
AND FINALLY, @runningnak3d FOR HIS EXCELLENT WORK IN ROOTING OUR DEVICE :good:

WHAT NEXT?
NOW THAT YOU HAVE ROOTED YOUR MOBILE, I WOULD RECOMMEND DOING THE BELOW TWEAKS FOR FURTHER ENHANCED EXPERIENCE....
1.THERMAL THROTTLING
IF YOUR ARE STILL ON A STOCK BASED ROM , I WOULD STRONGLY RECOMMEND TO RECONFIGURE YOUR THERMAL FILE TO PREVENT ANY POSSIBLE LAG WHEN USING EXTENSIVELY...
FIRST DOWNLOAD THE FILE BELOW:
https://drive.google.com/file/d/0B0W3xXHgfOxvLUpKNWhrWDE0TDg/view
USE A ROOT EXPLORER (PREFERABLY ES EXPLORER) AND GO TO ROOT/SYSTEM/ETC.
YOU SHOULD HAVE A FILE NAMED thermal-engine-8996.conf
RENAME IT TO thermal-engine-8996.conf.bak (JUST FOR A BACKUP IF ANYTHING GOES WRONG)
ENSURE THE ABOVE DOWNLOADED FILE IS IN .conf FORMAT
IF IT ISN'T , RENAME TO thermal-engine-8996.conf
NOW SAVE THE FILE TO THE SAME DIRECTORY VIZ ROOT/SYSTEM/ETC
GIVE PERMISSION TO THIS FILE TO rw-r--r-- USING THE ROOT EXPLORER ( SELECT FILE--->PERMISSION--->READ WRITE, READ, READ)
FINALLY SAVE AND REBOOT.
THIS WOULD OVERWRITE THE THERMAL LINKED PERFORMANCE OF THE CPU TO AVOID ANY LAG WHEN USING EXTENSIVELY.
2. RCTD REMOVER
ALSO I WOULD STRONGLY RECOMMEND TO REMOVE THE LG'S RCTD CCMD AND TRITON MONITORS AS THESE WOULD RUN CONTINUOUSLY IN A ROOTED LG PHONE AND CONSUME LOT OF RESOURCES...
JUST INSTALL THE RCTD REMOVER APP FROM BELOW LINK:
https://labs.xda-developers.com/store/app/com.zacharee1.rctdremoverforlg
GRANT SU PERMISSION AND CHECK THE DESIRED FILES (I CHOSE ALL THREE FILES) AND CLICK ON PATCH, FLASH IMAGE AND REBOOT (THIS WOULD PATCH THE BOOT FILE, SO AGAIN IT IS ADVISABLE TO CREATE A BACKUP OF THE CURRENT BOOT IMAGE USING TWRP OR WITHIN THIS APP ITSELF)
3. SCREEN CALIBRATION:
https://play.google.com/store/apps/details?id=com.grarak.kerneladiutor
INSTALL KERNAL AUDITOR APP FROM PLAY STORE AND GRANT SU ACCESS
CHANGE THE BELOW VALUES WITHIN THIS APP (SCREEN SETTINGS)
Minimum RGB value = 35
Saturation Intensity = 27
Screen Hue = 1520
Screen Value = 112
Screen Contrast = 132
THIS WOULD SOMEWHAT REDUCE THE BLUE TINGE AND GHOST APPEARANCES OF THE SCREEN
CREDITS: @Holyman007 for his thermal tweak @Zacharee1 for his rctd remover app

this would end up with a stock rooted phone with twrp recovery if all the methods are correctly followed..
......final result would be.... you would end up with a rooted stock rom with a twrp recovery....
your second screen will work perfectly.....
please let me know if you need a different thread for installing custom rom, and to reduce the lag., install sound mod to get maximum sound output and customize second screen... i will create a noob friendly thread for these as well......

Thank you, I've been reading up on the main lafsploit thread for awhile but I was still not sure about the whole flashing KDZ file and stuff so when you posted this thread it was a motivator to try it out. Got a day off from work tomorrow so gonna try it then so I don't got to worry about the time.
I'm interested in the max sound output and second screen customization if you got the time and its not to much to ask. If you want to wait till either someone else comes along thats interested or till I root just so you don't waste your time I shall update hopefully sometime tomorrow. Thanks again.

Abr1 yes I am rooted with twrp.
As I said, the commands to push magisk and twrp to sd did not work. I used usb otg in twrp to push magisk, but forgot to put twrp to flash as well.
I forgot that twrp had replaced download mode, so I was going a bit nuts trying to figure out how to get twrp to recovery. Lolol
Now I'm on latest update with rtcd removed thanks to the op who hosted it on xda as a flashable zip.

Hi guys, sadly I'm at the last step and got stuck.
I did everything, and managed to get to the part where you WIPE de data using TWRP, Mount, but when I go and type

While you are in the last step, in mount, select otg USB. You can push it to SD card and manual flash.
If you booted to system without magisk and flashing twrp, power off the phone, hold volume up, put in the USB, connect to PC. This will put you in twrp since download mode is replaced by twrp.
Now you can flash both files.

Lg V20 H910 (up to 20h) (root, twrp, and more!) Noob guide!

i am making this post because i have an lg v20 running 20h. there was no root guides available, so i decided to root mine using an older guide. it succeeded, but was very hard and time consuming. Being a noob at the time, i was also extremely nervous that i could possibly brick my phone or screw something up. i didn't, and no part of this should brick yours either. ***However - if you do somehow break your device in any way, that is on you. by completing these steps, you assume full responsibility. now that we have that out of the way, lets continue. at the end of this guide, you should have a rooted device with your choice of os (7 or 8 - or even a custom rom if you choose!). you should also have twrp. this guide would not have been possible without users runningnak3d and clsA
**** Also, during this Proccess, Your Phone WILL be wiped clean!!! don't forget to back up photos, videos, etc...*****
don't download any other files than from this guide.
1. download these files (required) https://lg-firmwares.com/downloads-file/4578/H91510e_00_VTR_CA_OP_1205.kdz (for a rootable os that we can flash, - get this also (required) https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222 this program is called lg up and has been patched to work with this phone. you will also need this. https://androidfilehost.com/?fid=1322778262903990218. these are the root files and need to be all in the same folder as where lg up is installed. you will also need to have access to fastboot and need to have adb installed. that is pretty easy, give it a google search if you still need help.
if you are running 32 bit, get this https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
this is the OS. get nougat, which has like three less steps (you can't upgrade to oreo on this os once rooted) or scroll down and get the oreo file. nougat (really old version) https://drive.google.com/file/d/1S82HVNt2rAtXgBY499IBJnoCVFnpCf_X/view
Oreo - get this first file, and the ones under it. https://www.androidfilehost.com/?fid=1322778262904015326
***https://androidfilehost.com/?w=files&flid=283977*** You have to have this file if getting oreo. if you chose nougat, then don't get this.
2. Now that you have everything downloaded and installed, put your phone into download mode. (power it off, hold the volume down button and plug in a usb c cable attached to your pc. don't stop holding volume down until you see download mode.)
3. once it is in download mode, open up lg up. select your device, (it should be in standby mode, according to lg up) and click dump (this is a total backup of the phone, you are lucky you know this right now, I didn't when i rooted mine) . it will bring up a file explorer, select where you want it to save to. (I chose my desktop). once you have a folder selected., it will bring up a bunch of options for partitions. click select all and uncheck user data. ****Make SURE that you don't unplug your phone during any part of this process or any other process in this guide, it will permanently brick it. ***** ow that you have selected everything but userdata, click start.
4. once that finishes, you will have made a full backup of your phone in case something goes wrong.
then click the partition DL button and select the h915 v10e kdz file (the file that i said was the rootable os we can flash) (the first file you downloaded). make sure bin file stays checked. then click start. once that finishes, your phone should automatically reboot into an old nougat operating system. then go to settings, enable developer options, and turn on usb debugging. that is easy, if you can't figure it out, google is your friend. now you should have no cellular signal. this is not the permanent ROM.
5. go to the play store and download terminal emulator for android. (once usb debugging has been enabled
then go ahead and go to the folder where you extracted the root files/package. hold shift and right click to open a command windows there or powershell, whatever your pc says. open 2 of those windows. then, in the first one, type, adb logcat -s dirtysanta
****don't close this window.*****
then in the other window, type STEP1.BAT
*****don't close this window.***** It may take a minute, but after a while it will let you type again. once you can, type run-as con
chmod 0777 /storage/emulated/0/*
6. then, pull up the window you used the logcat command in. leave it there so you can watch it
then, on your phone, go to the terminal emulator and type applypatch /system/bin/atd /storage/emulated/0/dirtysanta
once you do that, glance at the logcat window. once it says to run step 2, go to the window where you typed step1.bat. type STEP2.BAT
at this point, your phone should go ahead and reboot and say fastboot mode up at the top. now, go to your window where you typed all the .bats and type STEP3.BAT. wait until your phone reboots and you will see a screen saying that you can;'t use your phone. this is bogus, just ignore it and wait like 10-15 seconds for it to get past that screen. then it will boot that android and you should get a green screen.
Now, quickly, pull the battery from your phone. leave it out for a little while while we prepare the next steps.
If you want oreo, scroll to where it says OREO in capital letters. if you want nougat, scroll to where it says NOUGAT.
NOUGAT
use the file that you downloaded if you selected nougat - it should be a zip. it will be called h910-10r. DO NOT, I REPEAT, DO NOT UNZIP THE FILE. place it on a pre formatted micro sd card. then, place the battery and sd card back in your phone. also, unplug the phone. then, hold down the volume down key and hold hold the power key. once you see the lg logo, release the power key and immediately hold the power key again. then, you should get a screen that asks if you want to reset your phone. use your volume keys to navigate and select yes, then again confirm it. then, after letting it reboot, it should go into twrp. once there, go to wipe\and select format data. then type yes to confirm. then, go back to the main screen and click wipe again. go ahead and click advanced and wipe your dalvik cache. once done, go to home screen and click install. select the select storage option down at the bottom and change to sd card. then find the h910 zip file and install it. then go ahead and reboot your phone, you will have a rooted android 7 rom. you will also have signal. then download supersu from the play store and open it to have root.
OREO
use the file that you downloaded if you selected oreo - it should be a zip. it will be called something along the lines of full stock oreo rooted. DO NOT, I REPEAT, DO NOT UNZIP THE FILE. place it on a pre formatted micro sd card. also, go to your root package folder and find the twrp image file and put that on your sd card. then go get the mk200 zip file and also place that on your sd card. then, place the battery and sd card back in your phone. also, unplug the phone. then, hold down the volume down key and hold hold the power key. once you see the lg logo, release the power key and immediately hold the power key again. then, you should get a screen that asks if you want to reset your phone. use your volume keys to navigate and select yes, then again confirm it. then, after letting it reboot, it should go into twrp. once there, go to wipe\and select format data. then type yes to confirm. then, go back to the main screen and click wipe again. go ahead and click advanced and wipe your dalvik cache. once done, go to home screen and click install. select the select storage option down at the bottom and change to sd card. then find the oreo full rooted zip and install it then, install the mk2000 file. after you have done this, click install image and select the twrp. the reason you need to re flash this is because that oreo file re installs the stock recovery. then install the twrp. now reboot your phone. you will have a rooted android 8 rom. you will also have signal. then download a magisk 6.0 manager apk from chrome browser to have root.
IF this worked and your enjoying root give me a thanks.

This is redundant to the existing h910 root guide, all you did was copy their work and re-post it

Yes, that is why i gave them credit. However, It is more noob friendly and takes the time to explain what they are doing to their own phones as well as give them the option for nougat or oreo, something that none of the other guides have.

Ok, so I did it sucessfully, it's was still very complicated for me as some info is vague for a beginner. But after searching and retrying, and retrying, it worked. but go to runningnak3d post to get more info, and he wanted me to use sd card to root, but that did not work for me.. Your method worked for me. Thanks

your guide is good
+1 for for linking to the missing files from the old guide
+1 for mentioning me and @runningnak3d
you could break up the long paragraphs and bullet style the steps in order so it's easy to follow
theirs a video here of the steps and how the command windows should look > https://www.youtube.com/watch?v=jnRWnSHLGSc
this is where allot get confused in the guide.
I also don't remember you mentioning doing the battery pull after STEP1 when the phone sometimes hangs then run STEP2
I would also change the link to the H915 kdz to the android file host file in case LG changes it.
Their was a guy recently that could not get LGUP working you could make note that you may need the 32 bit VS 2010 > https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads
Any how, the guide is OK and the steps are not that bad, after a few tries most anyone can learn it.

alright, thank you so much for the advice! 1. i don't want to switch to bullets because when i was trying runningnak3d's guide, it seemed overwhelming. also people can comment on the step number that they were lost at. 2. i will change the kdz to something else if the file does change. i did in fact mention the battery pull step, if you ever need to find something in a page, hit control and f and then search the page.. i will add the 32 bit file. Thanks!

What a way to rip-off runningnak3d's guide.
I mean, I can understand rewriting it... I did the same. But, just to parse it out for me to follow better.
But your statement "...there was no root guides available..." is just BS.
Below is my guide... for me to do the process.
Creation date on the text file was November 7, 2017. Just over a week after runningnak3d made the original post.
Difference is, I didn't feel the need to post someone else's work, in an attempt to try claiming credit for it, due to nothing more than a "rewrite".
What you meant to do is this: (FIFY)

Search in You Tube for "How to Root install TWRP for LG V20 H910 Edition!" from user NewTechBegins. This is very good video tutorial, step by step.

Hello, so nothing happens for me after I enter the code into terminal emulator, what am I missing?

After all these done I'm rebooted to secure start-up where I need to enter password. Tried my 4 digit VIN and didn't work. As suggested earlier in this thread I pulled battery and wipe everything and install Oreo_full_rooted.zip, mk2000, and TWRP 3.3.1-0. It boots up the same to the secure start-up.
I might have done differently in process.
1. H91510e_00_VTR_CA_OP_1205.kdz I downloaded did NOT match MD5 on its download page. Tried twice and it was the same. I went ahead and used it.
2. I ran into "adb server is out of date, killing.." message but was able to download an adbfix and somehow got through
3. STEP1.BAT and the rest of BAT were not accepted in Win10 powershell so I had to enter them by hand and it went smoothly with no error
4. I used twrp 3.3.1-0 as suggested in NewTechBegins' youtube clip
5. Phone boots into scramble messages like shattered warning sign before LG logo appeals. It will eventually enter twrp or secure start-up after some wait. Takes longer than it should, 5 minutes or so.
Wish to stay on Oreo but might try the 10R Rom if I have no other choice.
Please help.
(Secure start-up appeared the first time after step 3 where it was supposedly be a green screen and I can pull battery. It didn't. It went to secure start-up. I pulled battery anyways and rebooted into TWRP, I was asked to enter password again. After a few wrong attempts I was able to bypass it and enter TWRP to proceed with install)
edit: Eventually succeed by not installing TWRP after flashing OREO and MK2000. Rebooted into Secured Start-up again, pull battery and rebooted into FACTORY Recovery and deleted all user data from there. Rebooted and Android setup began.
Note: BE SURE TO FORMAT DATA AGAIN in TWRP after flashing OREO and MK2000 to have a clean start. Would be nice if it was mentioned in this tutorial.

Dont try to install h915 instead just try dirty santa method which will install temporary twrp recovery there install h910 20h pre rooted 8.0 rom and install mk2000 v2.2 kernel and install newer version of twrp and you are good to go
No bricking risk and nothing dont try to do corss flashing of h915 its not that accurate also there is model issue in crossflashing instead doing that do dirsty santa and install h910 20h simple

So how do you use dirty santa method for h910 20h? All the guides I've seen want you to crossflash.

I didn't do crossflashing i first installed twrp throught dirty santa which then you have to open from recovery then there is android 8.0 h910 stock rom pre rooted i used or you can use your custom rom to flash then there is an kernel mk2000 file also to flash from twrp after you installed new rom for fixing errors like static screen and like that thats it also if you flash android 8.0 stock of h910 rom you will get a password during booting process just attempt it wrongs for many trys wrotten on it until you see wipe the data prompt and you will factory reset your phone and its ready to go maybe you will be promoted to twrp so you have to factory reset through wipe option ok and you are good to go one thing do it only on h910 not other model there is 0% chance of hard bricking your phone if you did this and no signal problem

I didn't do crossflashing i first installed twrp throught dirty santa which then you have to open from recovery then there is android 8.0 h910 stock rom pre rooted i used or you can use your custom rom to flash then there is an kernel mk2000 file also to flash from twrp after you installed new rom for fixing errors like static screen and like that thats it also if you flash android 8.0 stock of h910 rom you will get a password during booting process just attempt it wrongs for many trys wrotten on it until you see wipe the data prompt and you will factory reset your phone and its ready to go maybe you will be promoted to twrp so you have to factory reset through wipe option ok and you are good to go one thing do it only on h910 not other model there is 0% chance of hard bricking your phone if you did this and no signal problem

Ok,you know where to get the latest firmware and files? Most dirtysanta tutorials bat have the downgrade added. How do I just add the twrp without the downgrade? Any dirtysanta bat and files?

no no need to downgrade anything just find any video which says TWRP installation for LG v20 h910 dirty Santa and flash it but wait I seen in all zip files of dirty Santa there will a final step in that folder called step 3 that file is a batch file just open it in notepad and you will see there is written TWRP for I think us995 just rename it all of them to that name which TWRP in that folder ok for example if the name of the TWRP in dirty Santa folder is twrph910.img
you have to rewrite the same and exact name with .img in that batch file this ting will not tell any YouTuber or in the website cuz, I find it in curiosity and founded that the TWRP name was wrong so I just renamed it in that batch file and it worked before it it wasn't working also download the exact LG v20 h910 TWRP, not any other model TWRP or you will hard brick it man it feels so bad I one time hard bricked my LG next day I bought the device now I just sold it I change the mobo to LG h910 then I did all that root things and then I sell that phone no I have sony xz3 which is way better and have snapdragon 845 octa-core which is the thing I needed in just 135$ I found that it was japan model refurbished but has all things new and original like poled panel and stuff... well if you need more help just don't reply m on XDA you will not get the answer quickly here my social media account

reply me on that I am online all the time but not online on XDA all the time ok

Installed twrp no problem. Had installation issues (error 7) and edited the file. Tried it again and came up with error 1. Saw someone else on xda say to extract the boot img and mount to the recovery partition successfully. Welp, I guess I wasn't so lucky. I can not get into twrp recovery or any recovery and my v20 (910) boots into the Lg android splash screen. My desktop can not see any adb device but it registers a device being plugged in. What's the verdict, soft or hard bricked? Everything was cleared besides twrp prior to error 7 and 1.
