first we need to set v30 in edl mode.

This will let you reinstall bootloader img,

open the qpst that you download and install them, when you installed qpst go to C:\Program Files (x86)\Qualcomm\QPST\bin

you'll see QFIL.exe there.

open it , then on configuration click FireHouse Configuration, which will show Download Configuration

set Device type as UFS, and click restart after download, then click ok.

on set build type set it as Flat build, and on select programmer click Browser and direct to V30 Qfil folder ->prog_ufs_firehose_8998_drr.elf

now we need to set v30 in EDL mode.

then press all three button until screen turns off, when screen is off release the volume up button then click it constantly, if screen doesn't show anything but your computer make sound that is in good place.

if you did it correctly, on Device Manger you should find Qulacom ~~~ under Ports(COM&LPT)

you might need to try several time, it was hard to get the timing.

when you are successfully connected with EDL mode

Back to your computer.

Click tools -> partition Manger.

click confirm.

if you are getting bug try to press volume down and power button and try to get into EDL mode again.

you'll see some kind of partition list if you did it right.

now open P patch unzip it and open bootloader folder.

you'll find a matching img file there.

go back to QFIL and replace all of your matching img file by right click -> manage partition data -> load image

then direct to P patch.

when you did all of them, you should be able to use download mode (turn off using volume down and power button then connect to pc while pressing volume down)

your LGUP should able to find your v30

use partition DL to install KDZ.

if this didn't work try to replace abl, cmnlib, cmnlib64 in bootloader folder in v30QFIL that you download.

if that didn't work either try with this : https://drive.google.com/file/d/1YJB-d5CYfBj84N2e80sp9wXm_954zKMr/view

if everything worked correctly this should show android thing and constantly restarting or booted.

if it's constantly restating with android thing, press power button and volume down key then wait until screen goes down and show lg logo, when you see lg logo release power button then press it again.

it should direct you in to factory reset mode. click yes and yes and if everything goes right you should have functioning v30 again.
