[LG V30 Guides, News, & Discussion] tamakooo:
PART 1 of 3

Had trouble posting this in XDA, got flagged by the system so the guide is broken into 3 parts.

Attachments are in part 3.

This guide is as detailed as possible so that you won't make the same mistakes I did and won't face the same problems.

Thanks to [MENTION=1842686]xd4d3v[/MENTION] and [MENTION=4631519]conbak49[/MENTION] for your help buddies.

[TEXT IN BLUE ARE SPECIFIC TO LG V30]

THIS IS A MUCH SAFER AND EASIER WAY TO DE-GOOGLE / DE-BLOAT ANY ANDROID ROM AND IS WRITTEN SPECIALLY FOR THE LG V30, MIGHT WORK FOR ALL PHONES

AS OF POSTING THIS, I AM ON H930DS OREO ROM BUT THIS PROCESS MIGHT BE APPLICABLE FOR ANY ANDROID ROM, ANY VERSION

YOU NEED TWRP FOR THIS TO WORK. FOR ROOTING AND TWRP PLUS MAGISK RELATED PROCESS, REFER TO OTHER GUIDES ON THE V30/SPECIFIC PHONE XDA THREAD

Preparation

CHECK THAT YOU HAVE DOWNLOADED THE FOLLOWING APPS IN A FOLDER IN YOUR PC/LAPTOP)

(side note : the folder is in your pc because sometimes the phone's internal storage is encrypted and it is best to wipe all user data. We will copy this folder to internal storage after a clean install/factory reset)

A. TITANIUM BACKUP (download v8.3.3 or above from apkmirror.com)

B. Magisk 19+zip

(NOTE: if you followed @TxanMoe and @ChazzMatt 's WTF bootloader exploit for rooting the lg v30, be aware that the magisk.zip in that post is v18, you need magisk v19 for this process, but it is okay as long as you download magisk v19 from from "https://magisk.download/" website AND put it in the folder.

[ FOR THE V30, YOU NEED THESE EXTRA FILES IN THE FOLDER:

C. Encryption Disabler(Disable_Dm-Verity_ForceEncrypt_08.18.2019.zip OR no-verity-opt-encrypt - 6.0_1_.zip(OREO) )

D. LG ROOT CHECKER Disabler(AK3_RCTD_REMOVER.zip OR lg-rctd-disabler-1.0._1.zip(OREO) )

I am on oreo so I have the ones with red OREO, the first .zips are the latest and are probably for pie and oreo both ]

DISCLAIMER:

Although we are completely removing google apps pre-bundled in the stock rom; at the end of this process, you will have a fully functioning Aurora Store . It is the same Play Store side by side without any google trackers, and is from the open source MicroG project, so relax, you will be able to download all apps(Anonymously) including paid apps(with your login) just like you downloaded apps from the play store.

BEFORE WE BEGIN

TWRP will sometimes give a error message in red saying 'unable to mount storage/system'... This often happens if you were previously working on a different storage(OTG/SD card) and TWRP fails to switch storage. If it happens :

Go to MOUNT>STORAGE>SELECT STORAGE MEDIA>INTERNAL MEMORY and try again...it will get fixed.

WARNING:

NEVER EVER START REMOVING SYSTEM APPS WITHOUT BOOTING THE ROM/SYSTEM FOR THE FIRST TIME. SYSTEM WILL CRASH AND A BOOTLOOP WILL BE JUST AROUND THE CORNER.

STEP 1: VERY VERY VERY IMPORTANT

REMOVE YOUR GOOGLE ACCOUNT AND PHONE'S SCREEN LOCK PASSWORDS FROM SETTINGS>ACCOUNTS

DOUBLE CHECK that any google account is removed from settings.

DOUBLE CHECK that ALL FINGERPRINTS/PIN/PASSWORD LOCK METHODS HAVE BEEN REMOVED OR CANCELLED

IF YOU DON'T REMOVE YOUR GOOGLE ACCOUNT, SETUP WON'T COMPLETE WITHOUT GOOGLE APPS. YOU WILL GET ENCRYPTION ERROR AND MANY OTHER PROBLEMS (I learned it the hard way)

REBOOT [IMPORTANT]

STEP 2: IF POSSIBLE HAVE A TWRP FLASHABLE ZIP OF YOUR ROM READY IN THE PC FOLDER

if you don't have a twrp flashable zip for your system, it's ok. It's just a fail-safe method.

(Note: FOR the lgV30 you can download flashable rom zip from https://xdaforums.com/showpost.php?p=76584629&postcount=193 (at the very last of that post under UPDATE H930, US998, H930DS with latest stock firmware TWRP-flashable "ROMs" )

2.1 IF YOU HAVE A USB OTG/SD CARD

COPY THE FOLDER FROM PC TO USB OTG/SD CARD

STEP 3: back up your files from internal storage

It's getting WIPED/FORMATTED. Back up.
