Hello and thank you again for your support!
Unfortunately I still didn't understand the difference between "Refurbish" and "Partition DL" !? Where are the exact differences or what are the advantages or disadvantages of "Refurbish" compared to "Partition DL"

I'm recommending you use Partition DL if you change over to a different variant. If were were going to earlier firmware on same variant or cross flashing firmware from another region (like Italian H930DS to Australian H930DS), Refurbish would be OK.

But since you are changing to a compatible -- but different variant firmware (H930G to H930) -- use Partition DL.

FYI, I just saw this posted by ɐoɔɐɾ on Telegram:

Stock H93031a twrp flashable zip
This stock pie twrp zip should be able to be flashed after using aosp 10/11 without issues and might fix problems in aosp 10/11 which needs nougat to fix
Everything is already patched so no need to flash any other zips
(Base zip made by Seadersn I just replaced some files to fix some stuff)

H93031a_Fix.zip

drive.google.com

I haven't used it and I won't, since I don't have this model, but I thought that it might possibly be useful to others.

Who made this? Would like to give credit. Since adopting two school age children end of last year, I haven't had much time to peruse the Telegram group. I know JohnFawkes retired from most dev work, but at least they were nice enough to admit it was built on his work.

It's made by telegram user named ɐoɔɐɾ on LG V30 group (https://t.me/LGEV30).

He made also:
-Stock V300L30p twrp flashable zip
-Version One of universal bootloader unlock zip for everything model besides h932
-Stock US99830b twrp flashable zip
-Stock V300S30p twrp flashable zip
-Stock V300K30p twrp flashable zip

Thanks, @Dizzyrul3z. I didn't realize that that was a username until now, since it's just a bunch of backwards letters. If I had realized, I would've given credit, but I've edited my post above to give it to him.

* Do NOT update to Pie yet if you wish to unlock bootloader in order to root.
For bootloader unlock purposes, use the H930 Oreo KDZ versions with no later than July 2018 security patch: 20d or 20r.
Look at the names for dates in the title in that thread link. AFTER you unlock bootloader, then you can update to newer firmware (like this Pie). Flashing a newer KDZ (like to Pie) will not re-lock your bootloader.
With unlocked bootloader, then on Pie KDZ you can install TWRP and root.

Is this still relevant in 2021?
My LG V30 H930 was updated to latest Android Pie (V31a-EUR-XX, Security patch 1 Nov 2019), and I managed to unlock bootloader by flashing unlock.bin which I got from LG. I did that in Feb 2021.
(The guide to unlock bootloader on Android Pie I used: https://www.getdroidtips.com/unlock-lg-v30-us998-bootloader/)

Or does it mean that my root will fail cause I unlocked bootloader on Android Pie and not on Android Oreo? Can I proceed rooting it according to the guide without downgrading to Oreo?

That directive was for the 95% of LG V30 owners who would have to use the WTF Instructions for bootloader unlock and root. When people buy a new phone they have an urge to update to newest firmware, THEN go looking how to root. That's exactly opposite of what they should do as most LG V30 will need to use exploit found on earlier firmware.

There are only two LG V30/V30+/V30S models out of like 36 which have LG-sanctioned bootloader unlock and you own one of them (EU H930).

The statement was made NOT to update to Pie yet, because you need early Oreo at least TEMPOARILY for the WTF exploit. AFTER unlocking bootloader, THEN you could update back to later firmware.

Again, with EU H930 if you have your phone's unique LG unlock bin code, you can use that no matter which firmware you are on.

AFTER unlocking your bootloader with LG official unlock bin code you would still need to install TWRP and root. See this post below for that:

INSTALL or REINSTALL TWRP on PIE stock KDZ with ALREADY-UNLOCKED BOOTLOADER

IF for some reason you can't unlock your bootloader with the code LG gave you, then you would need to follow the WTF Instructions -- which include temporarily downgrading to early Oreo. You would also use our generic unlock bin code. Don't mix and match.

WTF Bootloader Unlock, TWRP Install and Root

Hello and thanks for your great instructions and help on this Forum!
Let's assume that I don't want to root my device.
If i just want to install TWRP and then install a custom ROM which does not require any "root checker disabler" nor "Dm Verity ForceEncrypt disabler" can i skip step 7. MORE TWRP ACTIONS of the WTF instructions?

After installing TWRP (and do a WIPE->Factory reset) will i be able to boot in my stock pie without problems, so sometime in the future install my prefered custom ROM from TWRP? In general can rooted Stock Pie survive alongside TWRP?

Thanks again for your time and help!

I would recommend root. Magisk, the method for rooting, also hide root. With just unlocked bootloader, all nosy apps (banking, certain games) will assume you are rooted anyway. You don't gain anything by unlocking bootloader, installing TWRP and then not actually rooting. They will assume you are rooted but you won't have any benefits (full control of your phone). This includes unlocked bootloader on stock ROM or any custom LOS ROM.

You are correct that LOS custom ROMs do not need root checker disabler -- but you DO need to disable the stock encryption for TWRP to read your internal memory when you initially install it on stock firmware. And if you are on stock firmware for any amount of time (an hour, a day, a week), do you really want that root checker constantly running in the background? Just run the disabler for goodness sake!

So, you might as well do both, as well as root.

When you start picking and choosing which instruction steps you want to follow, somewhere you will mess up.

I understand your point. So after installing TWRP is better not to boot in my stock ROM before flashing magisk, RCT and Veritry patches. Please let me explain my plan a bit further.
The rom i want to install is AiX which is based on stock pie but also comes rooted from the start. Also after contacting the developer he told me that "RCT disabler" and "verity patches" are not needed to be flashed cause the ROM "has all needed changes at system level".
So can i flash AiX immediatly after installing TWRP (before step 7 "MORE TWRP ACTIONS" of the WTF instructions)? The reason i insist is that i don't want to take unnecessary steps to achieve my goal. If i can install AiX winthout flashing any unnecessary patches i would prefer to do so.
So to sum up, can i procced all the way to step 6. INITIAL TWRP ACTIONS (including this step), then do a WIPE->FACTORY RESET and then install AiX?
Thanks again for your time!

Ah! OK, yes that is a very customized stock based ROM. Follow that dev's instructions.

New zip from ɐoɔɐɾ on LG V30 group (https://t.me/LGEV30).

Stock VS99630d twrp flashable zips
These stock pie twrp zips should be able to be flashed after using aosp 10/11 without issues and might fix problems in aosp 10/11 which needs nougat to fix (besides the System zip)

Everything is already patched so no need to flash any other zips

How can I Flash the KDZ file with TWRP?

How can I Flash the KDZ file with TWRP?

You can't
There are however twrp flashable zips available which you can use

You mean two Zip files with the stock Pie ROM? I'm going a little crazy and I don't know if it's worth it because I see so many comments with errors ...

 

[erickmurillo]

I have installed the KDZ and now I cannot enter recovery and I am not root either GRRRRRR

 

[erickmurillo]

WHY have I lost root and cannot enter TWRP?
