You can flash the kdz (stock file) for the update you have available by using LG Flash Tool 2014 (do a Normal flash).
The instructions and tools required for flashing a KDZ file are in this thread
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
The steps are roughly:
1. Find and download the correct KDZ file for your phone by following this link (replacing IMEI at the end with your IMEI)
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI
2. Flash the KDZ using LG Flash Tool 2014
3. Once finished flashing and the phone has rebooted, re-install TWRP and flash root
Cheers.

Thanks I'll give it a try

LGUP - NEW!!! - INSTALL KDZ - MM or LP - FACTORY RESET/UPGRADE

NEW software!!!!!...... LGUP WILL FLASH YOUR KDZ files
Download LGUP from here http://www.filedropper.com/g4 or here https://www.dropbox.com/s/d2dw48uqh4hku8m/G4.rar?dl=0 or here http://oceanhost.eu/eps4h4pmwphu/LGUP.zip.htm thank you hyelton for this link :good:
Install LGUP_8994_DLL_Ver_0_0_3_23 first and then LGUP_Install_Ver_1_14_3
Make sure you have downloaded the required KDZ file MM or LP
Start LGUP prog on your computer "make sure your phone is plugged in"
ARE YOU HAVING TROUBLE WITH LGUP NOT SEEING YOUR MOBILE?
Try this....... take the back off your mobile so you can get at the battery. Connect your mobile via USB. Start LGUP, if it does not see your phone DO NOT DISCONECT, DO NOT RESTART OR TURN OFF LGUP. Take out the battery and then put it back in.......let the phone restart on its own. LGUP should now see it.
THANK YOU FOR THIS Killerdog:good: <~~~To Modify This File You Must Have Root!!
For me it's show in LGUP as unknow device.
reboot my phone, remove battery and anything else don't work.
I install LG Bridge to test, and nothing seem to work.
After make some test and search, i find some info modified by S3V3N into his rom (cust partition) that he have modify into this file:
/cust/OPEN_COM/cust_OPEN_EU.prop
Code:
ro.lge.swversion=[COLOR="Red"]some info[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]some info[/COLOR]
change to
Code:
ro.lge.swversion=[COLOR="Red"]H81510c[/COLOR]
ro.lge.swversion_short=[COLOR="Red"]V10c[/COLOR]
restart my phone and woow it show correctly in LGUP and i can refurbish my phone.
TO UPGRADE TO MM from LP - make sure BIN file is ticked and in the File Path point it towards the MM KDZ you have downloaded. MAKE SURE YOU HAVE CLICKED UPGRADE! This will update you from LP to MM with out wiping any of your info. Press Start. Make cup of tea and be patient
TO DO A FULL WIPE AND INSTALL MM - Open the LGUP on your computer. FILE PATH point it towards the MM KDZ.
IMPORTANT!!!!!!! shut down LGUP!
Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section. Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient
TO GO BACK TO LP FROM MM - Open LGUP on your computer, click on FILE PATH and point it towards your LP KDZ. Close LGUP and re-open LGUP. Make sure you select REFURBISH this will do a full wipe, tick BIN file. Press Start. Make cup of tea and be patient
If you are worried about losing your data after a full wipe, why not use the LG Bridge software to backup and restore.... it works fine!
YOU WILL LOSE ROOT!
There is no need to enter download mode! LGUP will do it for you.

INSTALL TWRP
Make sure you have ADB and Fastboot installed.
I always put TWRP.img in the ADB folder - so if I want to boot into TWRP with out installing it this is what I do:
make sure you open a command prompt in the ADB folder "VERY IMPORTANT" and type:
adb reboot bootloader <enter>
fastboot boot TWRP.img <whatever your TWRP image is called in your ADB folder><enter> dont forget the .img at the end
That will re-start your phone straight into TWRP - You can transfer files to and from your computer while in recovery.
If you want to install TWRP permanently, copy your TWRP image to your mobile "while you are in TWRP RECOVERY mode" then press install then select images then select recovery NOT BOOT then swipe to flash. This method does not install TWRP app on your phone, all you need is a reboot app from the play store that will re-boot you into recovery.

Not sure but I'll put that in the op cheers.
Do you need root so use this method to upgrade to marshmallow ?
H81520A_00.Kdz flashed (by upgrade option) succesfully. It takes 10-15 mins(longest part is "android upgrading" screen.), and i lost root access. By the way root access is not necessary for upgrade.
So since it wasn't clarified, I'll be the one to ask...
Will this work on a unit without root (which is yes according to the OP), and without a bootloader unlock, ie the Taiwan (TWN) variant of the H815.
I completely understand it's a complete wipe and root will not be retained.
I would also like to know about this..... will it work on a unit with a locked bootloader... TWN variant?
downloaded from a different mirror re flashed no problems

False information shared by @Ernesto0023.
Following this guide will get you a secure boot error when attempting to boot into recovery. Even so following this guide is impossible because root is required and OP has no root on his kdz flashed MM.
My recommended solution would be reverting back to kitkat via kdz. If unfamiliar with the method follow this guide: http://forum.xda-developers.com/showthread.php?t=2785089
After reverting use the guide from post above: http://forum.xda-developers.com/lg-g3/orig-development/recovery-twrp-touch-recovery-2-8-2-0-t2966129
to flash TWRP.
Then fell free to flash whatever you want in TWRP. If stock lollipop ROM is you what you desire, download zip from here: http://forum.xda-developers.com/lg-g3/development/stock-t2961073
if stock MM is what you wish for download zips from here:

Even so if his MM would somehow be rooted it was still kdz flashed so it contains

Replace the recovery to stock recovery and relock the bootloader. If you installed the modified firmware, reflash the stock firmware, you will be good

Do i lose all my application data doing so.
No, I am using the stock firmware, so I suppose no need to reflash it.

Here you should find the stock recoveries: http://www.andromods.com/download-files/htc-one-m8-stock-recovery-verizon-sprint-att-tmobile.html
download the right recovery.img file and follow these instruction on how to flash - http://androiding.how/how-to-install-twrp-recovery-via-fastboot/ - in this just change the twrp recovery.img to the one you downloaded and run the code in command prompt.
It is recommended to do I clean install to avoid any further reported errors. Once you relock the bootloader you will lose all the data (like hard reset).

However, I have to ask, if I am on stock firmware; only rooted through SuperSU and with TWRP recovery,

First thing .. you cannot do OTA with a rooted stock ROM, you need a non-rooted ROM.
Secondly .. there is no need to relock bootloader - read the note in my thread.
Just read again post #1 and follow all the 14 steps, you should be fine.
Anything, you can ask in my thread as I'm not following your thread.

Can I add this to the Korean section of WTF Instructions?
Is this something specific, like upgrading to Pie with unlocked bootloader? Seems to be, just double checking.
So seems like I would note it in Section 9 of WTF, which is for Upgrading firmware after bootloader unlock?

Yes. You must unlock the bootloader in the oreo operating system (there is a tutorial with the Korean version). And you can update the new operating system pie with the loader unlocked.

You need to flash to H930 to access fastboot, with which you can use to flash TWRP then root.

Yes, you can install Netflix. Just use APK Mirror to download and install, not Google Play store.
After that, be sure to hide Netflix app in Magisk Hide.

The Netflix app from apkmirror it's outdated
Did you know if it's safe to install H930 30b if i'm in V300l 30h?
Does anyone know how to fix broken download mode?
I tried to root my phone but I failed among the many steps. I just flashed US998 ROM on my V300L because I f-ed up and didn't read my instructions correctly. And I didn't unlock my bootloader so I can't install TWRP. I tried to revert back to V300L ROM with LGUP but it doesn't recognize my device. And on download mode screen it says
Unknown B78
Unknown / E / L / RO
Also, I was on Pie
And I didn't find any solution to this problem online.

I don't understand.
What new files do you need?
What download link is dead?
All my WTF links are fine... Is it something where you flash back to Korean carrier firmware or something?
Um these files i followed ur instruction to go to a specific way to unlock lg v300L but the download links are dead.
First, Download files:
- LGup V30DLL_PATCHED
- LGup needs you to install download LG Mobile drivers
- kdz H930
- kdz Us988
- Adb.unlock.twrp.root
Depending on your variant (v300k / v300s / v300L) download one of the following files:
- For v300k: Rom zip v300k_21e (twrp) Rom running on us998 platform
OR
- For v300s & v300L: Rom zip v300s_21e (twrp) Rom running on us998 platform
All files are dead. I cannot unlock my bootloader because I cant download these. Thank you for responding @ChazzMatt
