Is it possible to downgrade the official software to lollipop ?
More info would be good. Methods?
You would flash the full factory image, skipping bootloader and gpt.bin... Do not attempt to OTA upgrade though as you will be in a mixed lollipop/marshmallow environment.
The real question is why would you want Lollipop, it is inferior to Marshmallow in every practical way.
There is no way to go back to 100% Lollipop.
To check if gps issue still exsists on lollipop (hw vs software).

Did your issues start after an OTA update? Just wondering what made you to think it might have to deal with the ROM.

All you have to deal with is just ignore gpt error and flash everything in correct order....
Well if u just want to get your system status official why to start from bottom when u already have lots of xml files present already...
Did some digging but couldn't find any useful information that is current regarding the Verizon LG V20 and rooting it.
I see there is a method for rooting firmware version 12a that supposedly works for version 13a but wouldn't know about that.
Does anyone know if it's possible to root the current version of the firmware? and where can I find a tutorial?
If not is it possible to downgrade from this version of the firmware to the latest rootable version and go from there?
My firmware version is VS99515A.
I'd really like to be able to unlock some features and get rid of the bloatware that is taking up quite a few GB's of space.
If not I'm not going to sweat it much as it's still a great device that would service my needs as is but of course if there is an option to have a better experience then I'll take it.

I was figuring this was the way based on some other places on the net. However I wasn't sure if 13a was properly supported for root or not. I know that 12a is. Any insight or confirmation that 13a is in fact rootable?
I came across the thread below and followed it but didnt pull the trigger because I didnt fully understand the process and if it was going to work. So im going to read this thread and see if I can make sense of things.

Don't think you have searched that hard...
All versions of Verizon firmware are downgradeable. This include everything from 11A to 16B. Yes, I have done it, multiple times. If you are on 14, 15, or 16 simply use uppercut to downgrade to either 12A or 13A. You can find the KDZ here:
https://lg-firmwares.com/lg-vs995-firmwares/
What about downgrading from 20C? Just bought this phone because the battery is removable but I must have root or all,is lost. :/

Hey there devs and V20 users alike.
As if there wasn't already hesitation enough to root this headache of a phone, and just when I was about ready to take the dive, I received the Oreo OTA update about three weeks ago.
Since updating, I've been enjoying the phone thoroughly.
If I'm going to be honest, this is the first phone I've owned (out of MANY since the Galaxy Captivate S days) that I have been satisfied using without root. It's an absolute multimedia powerhouse. However, little things like the inability to utilize ad blockers, tweak kernels, access root storage, etc. Does bother me now and then, although infrequently.
I'm looking through the forum here, and I'm beginning to think that due to LG's unbelievably long release of oereo, and the difficulty of root, devs have long left this device in the dust.
Unless I'm missing something, is there any rooted Oreo ROM available ATM? I absolutely will not revert to 7.1 again.
Thanks in advance!

root please
please dev, find a way to root my LG V20 F800S Korean version, Oreo. :crying:
In order to get root with Oreo on any model besides the H918, a custom kernel will be needed -- and I don't mean just compiling up the sources from LG.
I am going to try and migrate from my H910 over to one of my H918s .. but that is going to take a bit. Then I will have a phone that can use the eng. bootloader, and can actually start to work on it.

Hey Brian, glad to see you still around these parts lol
Edit
I thought the key to root on oreo with eng bootloader was the 996 oreo release or has that changed?
Sent from my LG-H910 using XDA Labs
Yea, I am definitely still around -- just nothing I can do right now.
I am pretty sure I can get it working with a modified kernel, but I need to be able to see logs -- so that means I need my H910

https://forum.xda-developers.com/v20/development/h910-att-lg-v20-stock-oreo-rooted-t3846384
Recently they have found out that to get eng aboot to work with oreo firmware, it was just a simple zip making modifying 2 files.
1. stock aboot changed to common dirtysanta eng aboot
2. stock v20 variant oreo boot changed to magisk patched stock oreo v20 variant boot
We have to keep the recovery as stock recovery so letting the previous twrp get flashed over.
The key is letting the oreo firmware boot up first time with stock recovery and then data will work like normal
Then we boot it up first time and it will get to system and then do quick setup and then go into fastboot (thanks to the eng aboot intact) to push the twrp recovery back to working order again.
So it was just simply doing that instead of using patchd lg up to partition dl to ignore the 3 things : aboot, boot, recovery.
That means eng aboot is still good to be able to use on oreo for all dirtysanta v20s .
I am personally running h910 oreo root with very early build of mk2000 beta 2 oreo kernel. My phone gets full lte data like normal. The battery drain is much improved from nougat while still having the same kind of performance I was used to on rooted nougat.
Asked this on other threads but no answers yet, let me see if I get my answers here
I have a f800l lg v20 not Rooted
Android 7.0
Updated security patch 1st september 2016
Kernel 3.18.31
Build no Nrd90m
Software version F800L 10g
My question is that can I update my Android to Oreo 8.0 which is available via Software update and then gain root access? If no, what is the last update limit for me to not lose rooting possibility. Or is it possible to downgrade to a previous update state after updating it to either Oreo 8.0 or other updated security patch levels? What would you suggest? I've heard Oreo is good with little battery drainage percentage as compared to Nougat which is my primary interest. I don't want to make a move to lose my rooting ability. Are there any other means available to upgrade to oreo without using lg software update in order to achieve both Oreo and root? And if it is not possible to achieve both Oreo and root are there any custom roms or kernels available with good battery drainage percentage? What would suit me the best. Sorry in advance for asking so many questions and not knowing if these questions have already been discussed and answered.
Thank you
Your phone is still ARB 0, so you can do whatever you want.
As for rooting Oreo, now that I know that it expects stock recovery on first boot, I will be posting zips for every model that has a KDZ.
You will need to root your phone first. Since you are on September 2016 patch, use DirtySanta.

by the way, no point in making the zip for h915 oreo.
I have tried with the same new method zip that was made with the 2 modified files + stock recovery.
The h915 modem just doesn't want to work with eng aboot whatsoever just like how it was on h915 nougat rooted.
please post oreo zip file for F800L, i can't wait to have oreo rooted on my F800L

Perhaps this is something that can be circumvented in the kernel, like runningnak3d was talking about earlier, and like emdroidle did for H990.
I don't know how it works, but I could try enabling the same fix that's used for h990, for h915 oreo.
thank you runningnak3d
Ok I'll llet you know once I root my F800 L
Update: I managed to flash twrp via DirtySanta method. I can get into recovery twrp and use it but i haven't flashed SuperSu yet. I can't get comfort view working and the battery is draining relatively fast, So by flashing super su will I get Comfort view and old battery drainage rate back or do I have to do something else? Shall I flash supersu? I get a red triangle mark every time I restart my phone which takes longer than it used to in order to boot, which means I have Bootloader unlocked, can unlocking bootloader ignite problems like long booting duration, inability to use comfort view and fast battery drainage? What do you suggest I do? flash supersu? or relock the boot loader without getting Supersu? Will doing so even fix these problems becasue I planned on rooting to get better battery drainage percentage, instead I get more battery drainage, please help @[runningnak3d]
Hello!
I have a rooted LG V20 H990DS running nougat. Can I upgrade to Oreo without loosing root?
If yes, could you please tell me what is the best way to do so?
Phone: LG V20 H990DS
kernel: 3.18.90-DOTS_H990_kernel-leicxan_jahlex-v1.4
ROM: stock
Build Number: NRD90M
OS Version: Nougat (7.0)
Can anyone tell me how to roll back from Pie beta to Oreo. Is there a proven and safe method? Thanks
Nope
No there is no way to downgrade, if you try to flash it, it will brick you device

Yes I know. You can not downgrade without losing data.
Wait warning. Remember to see if the kdz file have the same arb as your device firmware rn
A slightly different question about the H870S. I have one purchased in Australia from a big retailer in 2018. I have been checking for the pie upgrade but nothing has come through yet. When I looked up the details for the phone via the IMEI, I got the following:
Model: LGABCD
Region: ABC
Which seems kinda strange because there is no region ABC. The last update I received was sometime last year which was OTA and it says 1 May 2019, kernel version 3.18.71 build number OPR1.170623.032 Software Version V20o-AME-XX.
I was thinking I could use LGUP to upgrade to pie but I don't know which version of software to load. The OTA is saying there is nothing new available and LG Bridge is also saying there is nothing new available.
Ideas?

reporting. mine is kt korea telekom model G600K. successfully downgrade pie to oreo. downgrade because overheat and battery drain issue on pie.
the steps in the link work. but in LGUP, need to select 'refurbish' option instead of 'upgrade'.
of course, using the corresponding kdz file available at https://lg-firmwares.com/
Update 2: now back to nougat from oreo
Can anyone tell me how to downgrade LG G6 G600l Korea from android Pie back to android Nougat?
I had tried LG Flash Tool and LGUP with nougat kdz file from lg-firmwares.com but nothing work.
in LG flash tool it alway told me to contact the system adminstrator.
in LGUP it said the LAF protocol version is not match.
What should I do now?
Did you check ARB by going into hidden menu *#546368#*600# (Ver. Info..)
I have G600 too and i have changed between S/L as well as downgrade from Pie to Nougat..
Edit: First check ARB, if its all 0 then there is a way with patched LGUP1.15 to even cross flash..LGUP1.14 always gives errors, never 100% results in first try..
