* 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.
