I attached image to my previous post. But instructions are also in this thread. Pay attention not only to numbers 30b, but also to security patch date. As you can see it is different for different LG G7 phones.
They must be the same, otherwise you will get bootloop.
I haven't been able to get the boot file that you linked initially and I thought it was expired. It was my PC security that was blocking access though. I have since downloaded on my phone, copied to PC and rooted the phone. No bootloop.
Thank you for your reply.

I also have TIM, I have installed the 807 KDZ file. Is there any way to extract the boot image from my device or from the KDZ file? I would love to patch Magisk to it myself. After patching boot image w/ Magisk, Magisk is a little bit "broken" and shows Magisk version as N/A, all apps have root access but there's no prompt for it (a bit of a security issue, imho, and also no control over hiding and such).

Android 10

EDIT:Extracted boot.img using firmware extracting tool

    Magisk 18.0+ for the LG G7 ThinQ

    This is a collection of Magisk pre-patched/pre-rooted Boot images i made for the LG G7 ThinQ European model (G710EM). This thread will also guide you how to

    If you happened to have a G7 ThinQ (G710EM) or any other model that is running European Oreo/Pie firmware AND it's bootloader unlocked you can easily install a boot image according to your firmware version.​

    Warranty void and a disclaimer:
    Disclaimer: I'm not responsible if you break/brick your phone, be transported to place in or outside the universe, cthulhu deciding he had enough of you/us or the big bang but in reverse. Happened too many times already.

    Warning: You have to choose the correct firmware version otherwise you may not boot

    Warning: This is only for the European firmware. Other firmwares are not supported and it's not guarantee you will boot

    Step 1: Unlock your bootloader.

    Step 2: Install Magisk
    If you just unlocked your bootloader you probably still have the files you just used and also got a little bit familiar with fastboot.
    If you don't have them read Step 1 and download the tools linked there.

    First before you do anything we need to know what firmware version are you running (very important):
    • Open "Settings" on your phone
    • Navigate to "System" Tab on the left
    • Scroll down to "About phone"
    • Go to "Software info"
    • Look at "Software version"
    Now there it should say your phone model + firmware version
    Your firmware version should look like " 10j , 20b , 10q etc.. "
    Or any combination of that sort. Remember it.

    Now go to the collection of boot images here:

    There are folders with different firmware version. Go to the one you just remembered. (Ignore the ones with G710N on them)
    The layout of the folder is:

    boot_ xx .img            - Stock un-edited boot images. For when you want to go back.
    boot_ xx -magisk.img - Magisk pre-patched one. This is the one you're looking for.
    twrp_ xx .img           - TWRP Recovery boot image. Not useful for running Stock firmware. Ignore it

    Download boot_ xx -magisk.img . This is the one you need.
    Now, using the tools from before open your command prompt and type:
    fastboot flash boot_a [location of your boot image file]
    fastboot flash boot_b [location of your boot image file]

    The best way to get the location is to "drag and drop" the file inside the command prompt.

    After successful flash reboot the phone using the power button and you will have Magisk installed on your phone :victory:

    Congratulations you did it!​

    I've just uploaded it on GDrive if anybody else need the v20h (stock + patched)
    Greetings from Athens/Greece. I have an unbranded Spanish G7.
    I assume you have the USB debug enabled on your phone.
    use lg bridge and ask it to perform the update. Once the update is found, it starts downloading the kdz. This is stored at
    %USERPROFILE%\AppData\Local\LG Electronics\LG Bridge\SWUpgrade\Image
    Downloading takes sometime. Go to that directory and check the name of the file
    Once this is done, it starts copying the kdz to your phone. This is the time to copy the kdz to another directory so you can work with it.
    You can create a cmd file to do this copy, so you will not waste your time waiting for the whole file to be downloaded. This is the cmd I created.
    This checks every 5 seconds if the file has been fully downloaded. Once it has been downloaded, it copies it to your home directory and exits.

    echo starting
    timeout 5
    copy "%USERPROFILE%\AppData\Local\LG Electronics\LG Bridge\SWUpgrade\Image\*.kdz" %USERPROFILE%\ 
    if ERRORLEVEL 1 GOTO begin

    Wait for LG Bridget to finish the update and reboot the phone
    To create the images yourself, you need LG_Firmware_Extract_v1.2.6.1 tool.
    You select the kdz file, tick the dz file, then you press the "Extract KDZ" button and wait for the extraction to finish.

    Then you select the dz created at previous step.
    Scroll down the second box and tick the file named boot something. Press the "Extract DZ" button. This will get you the default boot.img.
    (I hope you can see the second print screen as well)

    Copy this boot.img to your phone
    Open magisk manager. It should complain that magisk is not installed. Click install and select the zip file you uploaded. This will create the magisk_patched.img needed for your phone. Donwload it to your PC and then business as usual:
    adb reboot bootloader
    fastboot flash boot_a magisk_patched.img
    fastboot flash boot_b magisk_patched.img
    fastboot reboot
    Good luck
    thanks stel67 for tutorial

    is working!!!!
