[LG V35 Guides, News, & Discussion] cloud1250000:
IF YOUR BOOTLOADER IS NOT ALREADY UNLOCKED, THIS GUIDE IS NOT FOR YOU.

READ EVERYTHING AT LEAST ONCE BEFORE PROCEEDING!

THIS GUIDE WORKED GREAT FOR AT LEAST 3 PERSONS, THIS DOESN'T MEAN IT WILL WORK ON YOUR PHONE.

This guide exist in case the ULM Q never released :)

This guide should do the following :

relocalize to your country (I'm only providing the files for canada, usa and eu)

Root and TWRP (useful if any custom roms get released)

debloating

volte/vowifi/vilte/viwifi

Very Good battery (see screenshots down below)

mute shutter camera

4k 60fps video recording (?some people said it wasn't available on the korean Q?)

wifi tethering

and more

WHAT'S NOT WORKING FOR ME :

lg smartworld : meaning no lg app update.. which can lead to the next problem

Drag down for search : working only if you do not update the google app

What you need:

1 to 2hrs of free time

Working QFIL with minimal knowledge

Working Fastboot on your pc (See spoilers)

Also, this guide assume you had working volte/vowifi on your phone at some point...

Because, you will need the carrier folder from the /oem/op/ folder.. should look like this : open_us, vrz_us, open_ca..

Or you will need to retrieve it from your working firmware...

I'll be providing :

- Android 10 - G7 - OPEN_CA (Canadian operator folder) (What I'm using on my phone right now)

- Android 9 - V35 - OPEN_US (ULM/GFi) (Confirmed working by @cmrntnnr)

- Android 10 - G7 - OPEN_EU (untested) (thanks @vlad48)

!!!!!! Before crossflashing to the korean kdz !!!!!!

------------------------------------------------------------------------

Crossflashing can break stuff sometime.. it is advised to do a full backup of your phone using https://github.com/bkerler/edl

if you're feeling lucky and do not want to do a full backup... you should still use qfil to atleast backup the following VITAL partitions : Fsg, modem, modemst1&2, ftm

STORE THOSE FILES PRECIOUSLY

------------------------------------------------------------------------

File you need to download :

To your phone SDCARD :​

OPEN_CA or OPEN_US or OPEN_EU (untested)

(Decompress this file, delete the zip)

OPEN_CA is too big, I had to delete apks that weren't from my carrier. (Bell)

(open_ca/apps/ -> kept only bell apks)

debloated-priv-app-RENAME-ME.zip

(Decompress this file, delete the zip)

debloated-app-RENAME-ME.zip

(Decompress this file, delete the zip)

twrp-installer-v3.3.1-v35_a.zip

Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip

Magisk

(OPEN_EU only) : voenabler-v1.8.zip

​

To your pc:​

vbmeta.img

30b_boot_magisk.img

30b_abl.bin (shouldn't be needed, but provided as backup)

Korean Q 30b (I went with LGU_KR since the other one weren't available back then)

The V35 engineering abl you got from here : https://xdaforums.com/lg-v35/development/bootloader-unlock-root-instruction-t4052145

This file was renamed to

engabl.bin

in this guide​

You need to use SOLID EXPLORER, not esfile or any other since I can not guaranteed it will apply the correct permission to the files and folder.

LGUP > Flash V350N30b_00_LGU_KR_OP_1015.KDZ using partition DL, select everything except FTM

Let the phone boot for the first time and reach setup screen

LGUP > refurbish phone using the kdz (this should

fix potential nt error

when booting the phone, it did for me)

Let the phone boot for the first time and

setup the phone quickly so you can install app. (no lock or fingerprint)

Patching vbmeta to edit the operator/carrier information & patching boot for magisk/root

Reboot to system,

Install

magisk manager and

solid explorer

Start magisk manager and let it reboot your phone

magisk > modules > install from storage >

twrp-installer-v3.3.1-v35_a.zip

SOLID EXPLORER

> copy the carrier folder to the

oem/op/

partition ('OPEN_CA' in my case)

SOLID EXPLORER

> edit oem/op/cust_path_mapping.cfg and replace LGU_KR with OPEN_US ('OPEN_CA' in my case)

SOLID EXPLORER

>

Rename

the folder /oem/op/LGU_KR to LGU_KRori (this will make your phone lag/glitch/freeze real quick.. proceed with the next step ASAP)

Quickly go in magisk and use the reboot menu to get to twrp. (reboot to recovery)

Format data

Reboot to TWRP/recovery

Flash Magisk-v21.1.zip, if it doesn't flash, reboot

using the reboot menu

to TWRP/recovery again until it works. (no red text)

Flash Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip

Reboot to system

if the vowifi toggle is not working for you

For OPEN_CA/OPEN_US :

FOR OPEN_EU : (these steps are from the v40 community telegram, Quote from Lucky)

Optional.

Adding back missing lg apps (I provide QMemo and LG Weather)

Enable LGMessage over Google message and add back LGFMRadio (you'll need to uninstall any sms app you might have installed.. like google message or fb messenger(if used for sms))

Thanks to everyone patient enough to answer my questions and who did provide most of the solution for this guide:
