Where can i find the excat Version-name? (Italy/Open EU etc.)

Really I do not know. My phone was a branded one (TIM operator) so I assumed that my version was Italy TIM. Actually I read v20h-EUR-XX in software info menu... perhaps I've got the Open EU too?

@jonsat,
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.

Code:
echo starting
:begin
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:
Code:
adb reboot bootloader
fastboot flash boot_a magisk_patched.img
fastboot flash boot_b magisk_patched.img
fastboot reboot
Good luck

@stel67
Do you know if there's any TWRP recovery we could boot via fastboot with stock rom?
Would be way easier to just flash Magisk in there (and/or pull the stock boot.img from there).


But thanks for the guide :)

Thank you very much for the explanation... however, I've already done the upgrade via OTA, so now LG bridge won't download anything since I already have the latest firmware installed.
Curiously, I can't find any 20h kdz version around... where did you find yours?

From lg bridge, as written above!
You can also download it from
https://lg-firmwares.com/lg-lmg710em-firmwares
If I were you I would wait for the next OTA and then apply the post above.

EDIT: I managed to redownload the firmware, using the "recovery update" function in LG Bridge! :)

UPDATE: BINGO! All went flawlessly... extracted boot.img and patched into Magisk! Thank you very much @stel67 and greets from Italy. :)

i don't know if it's a lgup problem or magisk, ill write it here too
the ram management is terrible and i always have like 200mb free, so i said to myself, let's remove some unused root apps...
all ok but then i try to reboot and the phone goes to fastboot.
No problem i say; let's try the LGUP upgrade and i should be fine...
now the phone boots but magisk manager says "no magisk installed", so i try to flash magisk img to boot_a and _b but it doesn't work and i don't understand why.
any idea?

no errors at all, just as i did the first time to get root (fastboot flash boot_a [location of your boot image file]
fastboot flash boot_b [location of your boot image file])
the lg smartworld app even says that i have root and force close, but no root here
i've tried to reflash boot 3 or 4 times with and without magisk manager installed, don't know what to try except total reflash that i would like to avoid

ps. tried installing supersu and it says su binary occupied

Hi folks!

I have G710EM, `V10p-EUR` firmware. I upgraded from WITHIN Magisk Manager, from Magisk v18 to Magisk v20.3. Terminal window opened and did some unpacking of the boot image, patching and reapplying. I am curious: is this the right way to update magisk, will I able to boot once I restart?

Thx ill see what can i do without brick the phone again, i would like to have root again just to backup whatsapp without using gdrive to restore after ill reinstall the new rom
You can backup whatsapp without root too.
Just do a local Whatsapp Backup and copy the "Whatsapp" folder to your PC and after reinstall of the rom back to your sdcard. Then our can restore from that backup when reinstalling whatsapp.

If you need more instructions just Google it.

    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:
    https://drive.google.com/open?id=1NtbfxAbYLeQNryPg0odgLa8hBgabrH3j

    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:

    Code:
    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:
    Code:
    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!​

    @jonsat,
    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

    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.
