LG V50 ThinQ
This process is been taken from this link -https://forum.xda-developers.com/t/guide-how-to-recover-lg-g7-or-other-newer-lg-phones-from-edl-or-9008-mode.4213851/

I just made few changed and it worked for me

credit all goes to sourabh7625 and ThangPC for sharing backup files
( if you need any help contact them ) it worked for me so iam just trying to help other that's all .

Tools Needed -
Before you install these tools uninstall all the mobile related drivers

Qualcomm USB drivers. https://mega.nz/file/YAVhFIiC#nF-cChZklhcsxMHk24GhsB6rlE119erQqmXuBu21c6c
LG mobile drivers. https://mega.nz/file/4UU3RSJb#iJu32uFbPsSrhIPoVr-BS1f2RqHnqL95lePDhDnK7NY
QFIL tool. https://mega.nz/file/4AdjXCAS#tWf6XUYO3OxHjZ_XDJZopOtQpVkggW2170QIKDW0JK8
prog_ufs_firehose_sm8150_lge.elf
Lg v50 Backup files - https://drive.google.com/file/d/13AJ8SnKmpOrTQF2EQ1odJK7-4qfUTIdF/view

* Steps :
Step 1 : uninstall all the phone related drivers and restart PC.

Step 2 : to successfully install drivers and software follow below guide -
a. open commant prompt with admin rights run these commands so windows can allow to install driver properly.
- bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
- bcdedit.exe -set TESTSIGNING ON
(these will disable driver signature enforcement and put windows into test mode)
and restart
b. install Qualcomm drivers
c. install LG mobile drivers
d. install QPST
e. Install lg bridge

Step 3 : open QFIL from it's installation location and check build type to flat build and in programm file select prog_ufs_firehose_Sdm845_lge.elf file and in lower right corner select storage type to UFS.

Step 4: connect your device to PC and boot into EDL mode by
a. if it is in any ON condition : POWER button + VOLUME DOWN and prepare to press VOLUME UP repeatedly as soon as phone switches off
b. if it is in dead condition : connecting to PC automatically boot into EDL mode.
if phone is connected in EDL mode now Device manager must show a device under ports tree somehting named as Qualcom HS-USB QLOADER 9008(Com_X)
* if you have bricked your device then I assume you already know how to boot into EDL mode.

Step 5 : now in QFIL select port and select your device, select Tools from QFIL toolbar and select Partition Manger, in warning window ckick OK if you've selected right prog_ufs_firehose_sm8150_lge elf file and after success it must show a list of many partions of your phone.
flashing : it's time for flashing.

Step 8 : After selecting all the rawprograme files click on Download and it will take time to download

Step 10 : Use LG Brige tool from lg website to download the official firmware for your model

Friend i win this battle, follow this:
1. download the Korean KDZ
2. download the .exe version of KZDtool here: https://bbs.lge.fun/thread-69.htm. Btw, the link in the tutorial has been outdated, I found the correct URL using Google: https://www.lanzoux.com/ia1u5ub
2.1 you need to extract the KDZ preferably the old version with android 9.
You need to download the python extractor, it is the only one that can extract all the images from kdz
3. Download the v50unbrickbackup https://drive.google.com/file/d/13AJ8SnKmpOrTQF2EQ1odJK7-4qfUTIdF/view
4. join the folders with the images and the .bin
5. download .raw files that i make https://mega.nz/folder/dAYzySqA#IMxrMAZeBCaAuUZ_eFB6Uw ('this raw file have a join files img and bin file
(notice that there is a mix of img and bin files.
This is due to missing some files from step 2)

6. put your cell in EDL and open qfil, select all rawprogrames with ctrl+a, and download!
7. After process, your phone go to download mode.
8. In LGUP, select refurbished, and join
(in this step i tried a few times without success. The process failed midway.
But after 2 attempts, success!)
can you explain in detail step 2.1 what file i will get after extracting kdz? can i just use LG Firmware Extrat tools?, and step 4 'join the folder' which folder?, step 5 where should i put this file? . Thanks in advance.
