hi folks!
I am pretty confused now. I am looking to get the V20 H990DS, but i am more confused now after reading here. My questions:
1. Is Bootloader unlock possible?
2. Can i install TWRP?
3. Can i root?
4. There is LOS official i know, but is the problem with 2. screen now fixed / going to be fixed?
Seems so good of a device, but i am insecure about it now after reading here. My old Mi4/Cancro is one of the best supported phones out there, so i dont expect it to be the same with V20, but i need working LOS with Root and working 2. screen (or the outlook on it working in the future) to be confident in buying it.
I hope you forgive me my nood questions,
Greetings
With sadly no replys, let me add what i know now:
1. + 2. + 3. Still no easy way in sight AFAIK. EDIT: To be clear: There IS a way, Dirty Santa, but the instructions are somewhat too complicated to be confident with trying. Have had rooted Phones with custom ROMs since over 5 years and never again a stock device, but i dont dare it. The 300€ i payed are much to much to have spend it on a bricked device. Will try to find more dirty Santa noob friendly explanations and post them here. EDIT2: For those who DO dare it, here the thread: https://forum.xda-developers.com/v20/development/dirtysanta-h990-t3624296
4. Second screen still a problem, nothing new heard for quite a long time.
Anyone with knowledge to add or correct, please help! Stock ROM is not as bad as i thought, but without Root, Android is not fully usable for me.
thank you pro for this thread
very useful for me.

i dont get about your complain. you said already using phone with root for 5 years so i guess you've been here on xda for a while. if you really want a phone which support custom rom go with phone which support unlock bootloader like HTC, Oneplus, or even xiaomy. its not that hard finding them on XDA. 300euro for briked devices? well, if you read v20 section carefully you knew most people here bought this devices for the camera, audio, and other things like removable battery, etc. i never found someone who bricked their devices while rooting here, even if they do we already had flasher tools like LG up which already tested fully working by some members. and whats the problem with second screen? its working for whatever it made for. are you expecting to watch movie on those 2.1 inch display? i had lg v20 h990ds rooted with magisk and had no problem so far. bought some apps like grenify and titanium backup for debloated and my phone rocking solid for abouth 2 month. if you cant wait for LOS just bought lenovo zuk2 or oneplus 3t on the same price range.
No problem doing 1+2+3 with DirtySanta exploit/procedure. It's not as complicated or dangerous as it might seem from the instructions. I thought I had soft-bricked my phone twice after rebooting normally with the old kernel instead of straight to TWRP to update the kernel first, but it was easy to re-flash the 10d factory firmware file I had and start over again without any issues both times.
Basic summary of procedure:
1. Flash factory firmware version earlier than 31 December 2016 (only needed if installed firmware version is after 1 January 2017).
2. Do DirtySanta exploit to unlock bootloader and install TWRP and root.
3. Use kdzwriter to update phone's system/modem/cust partitions to latest firmware version without overwriting unlocked bootloader/TWRP, reinstall root (SuperSU or Magisk) from TWRP.
4. Disable automatic OTA updates so that any future firmwares won't automatically install and overwrite bootloader/recovery and remove root and set ARB 1. If that ever happens then TWRP/root will probably be gone forever.
provided you follow the instructions carefully, it's safe to root with DirtySanta.

Using the steps on #3, would it be safe to say that we can update the device to oreo and still keep root?

No, right now if you update you'll lose root as the engineering aboot isn't compatible with Oreo and you have possibly non working data, invalid sim issues etc

Too bad. Your earlier post actually got me excited. Hehe. Anyway, hopefully someones starts working on rooting the oreo firmware.
The short answer? @Stele88
Yes. To all of it.
The long answer starts with the Dirty Santa root process. Believe me, I was daunted by it as well, but as long as you follow it (or the noob version of the guide you can find by searching around the same section the original guide is in) and take your time, you'll be okay. It's what I did and I'm now where I am today.
I'll address a couple things since I have the same device as you. If you want to get your device working properly on LineageOS/ResurrectionRemix (LOS with more customisation) then it's a long process.
1. Start by following the bootloader unlock process for Dirty Santa. Depending on what firmware your device gets shipped with, you may need to downgrade to (in the case of the H990DS) the v10c firmware. Once done, then you can Dirty Santa the bootloader and get it unlocked.
2. Once that's done and you're rooted with the initial TWRP from the thread installed, you'll want to look into KDZWriter. It's a program by the same emdroidle who did the Dirty Santa process for us that allows you to update your STOCK system software to newer versions and keep root. You can use it for example with the H990DS firmware KDZ files and go from rooted 10c -> rooted 10f -> rooted 10xx -> etc. until you're on the latest available 7.0 KDZ for the H990DS. This will be the longest part of your process, but it ensures that everything is up to date before going to AOSP/Lineage/Resurrection, specifically the modem partition. I recommend using the TWN region of firmwares if you're just going to convert to a custom ROM anyway, but any region will work fine (the only real difference is that, for example, the Australia region of firmwares comes with more bloat than the TWN region).
2b. You can also use KDZWriter from an updated TWRP you can get in the thread by Phoenix591, his latest TWRP versions have KDZWriter built-in so you don't have to run it off the computer, you can do it all with the kdz files in recovery.
3. Yes, you can root using the Dirty Santa method on v10c kdz firmware. I recommend Magisk for root over SuperSU.
4. There's no official LineageOS that is as up to date as the unofficial ones, and there's no official ones with second screen enabled full stop. That being said, the unoffcial LineageOS 15.1 by x86cpu has been my rock solid daily driver for about 2 months now and I've never had any issues that stop me from using it. The same can be said for ResurrectionRemix 6.2 by Blaises. To use either of these, you will need the updated TWRP from Phoenix591.
4. Second-screen enabled builds of LineageOS and ResurrectionRemix do exist, and in this case ResurrectionRemix is (as of this post) more up-to-date than the LineageOS 15.1 second screen version. If you find yourself needing additional features that aren't in the stock kernels for those ROMs (such as KCAL configuration to help with burn in, among other things), then I maintain the second-screen version of the Gamma Kernel by Omar-Avelar. People are successfully using this with second-screen ROMs and have full functionality. You can purchase the app BoredSigns from the play-store to add additional functions to the second-screen.
As I said at the start, it is a long process, but a very worthwhile one. The jump from stock to custom-ROMs is absolutely incredible. Again, in short, yes. You can get everything you want.
Just do your searching around the forums for the processes I outlined above, ask any questions you have, pre-download your kdz firmwares from HERE and any software you need, and just take your time. It's maybe a couple hours to get setup with a rooted stock system that's up-to-date, and maybe another hour or so to go from stock to Lineage/Resurrection.
P.S: If all goes well with the Dirty Santa process, but you get screen distortion after rebooting when flashing the TWRP from Dirty Santa, just pull the battery instead of rebooting.
Good luck, good searching, and remember to not be afraid to ask questions in the relevant threads.

It's highly doubtful this will happen, but one can hope. Right now the best way to get Oreo is through a custom ROM, purely because of how security is implemented by LG in the stock Oreo ROMs.

Actually it is possible runningnak3d has already said awhile ago he has a process to root stock oreo he's just not releasing it yet so LG can't patch it before the Oreo roll out is complete

So, I have a 32gb Amazon-variant XT1625 on MPJ24.139-48 with an unlocked bootloader and root. I want to update to Nougat, but it's looking like setting up to take the Amazon update is going to be a fair amount of effort; I'm wondering if it's possible to just flash the retail version of Nougat since it's looking like I'm going to have to go to a fair sum of effort anyway.
I've also heard that Moto G4 Plus ROMs will work on the G4, but I don't know the specifics on that.
i dont see why not as long as you already unlocked the bootloader prior to Moto(Lenovo) disallowed unlocking of amazon varients of the g4. heres a link to the stock nougat firmware
https://androidfilehost.com/?fid=673368273298955218
I flashed -64 retus software on mine and it immediately had two nougat updates afterwards. Still waiting for one that fixes the aboot sector vulnerability too but never know when that may come

then you was able to flash retail version in a amazon prime phone? I have one and it dont boot if i instal a retail version.
di anybody actually get this working? I had the same issue as @iurd2007 I was able to unlock the bootloader just fine. The flash appeared to have taken successfully. But it just gets caught in a boot loop when trying to reboot the system after the flash. I followed the instructions here:
https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
okay, so i've tried various roms both official and unofficial, as well as even the stock Nougat and Oreo flashable roms found here:
https://forum.xda-developers.com/moto-g4-plus/development/rom-oreo-8-1-0-soak-test-t3873367
So far, the only ROM i've been able to get installed is omni rom 9, but it keeps crashing several apps over and over on the setup wizard. I've read somewhere that using a different version of TWRP recovery image might help. I've tried the official TWRP recovery from twrp.me, the patched arm64 version found here: https://sourceforge.net/projects/tw...3-r1-athene-arm64_rajatgupta1998.img/download , also the latest version patched for efs backup/restore here: https://forum.xda-developers.com/devdb/project/?id=29106#downloads. So far the the one that seems to work the best is the third version of TWRP. It would be nice if all these custom patches made it back into an official release, but it's probably asking a lot of a phone that is almost 4 years old at this point. and a budget friendly phone at that.
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!

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.

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.

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]

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?

I went through many existing threads only to get myself confused. I want you guys to help me get back to stock ROM so that I can get OTA updates.
1. I have working volte and IMEI till now. I didn't take back-up of persist or efs as I was lacking knowledge. Can I take back-up of those now for going back to stock. If yes then suggest how?
2. I don't remember my build number from which I unlocked my bootloader. Should I lock the bootloader again to get OTA? If not then please suggest any way to get back to stock whether Oreo or nougat (get updates to Oreo then).

From what I believe, you should definitely backup your EFS and Persist right now while it's all good.
If you don't remember your last stock build number, it is safe to use the latest build for your region.
Once you flash a fastboot ROM and everything's good to go, there's absolutely no need to relock bootloader as the script in the OTA only checks for system modifications and if it finds any on your phone, the OTA will not be applied and the update will eventually fail. To ensure that you are able to apply OTAs without any hassle, I recommend you don't do ANY system modifications like root or camera mods or similar. Stick with the core OS and you'll be good to go.
You can alternatively use TWRP flashable ROMs by @NZedPred, they're like a newbie-proof solution to getting to stock ROM from virtually any ROM without losing any functionality as they only flash the OS part of the ROM and rarely do any changes to the HW functionality of the ROM like Radios and Sensors. If all else fails, you can always flash a TWRP flashable stock and be ready to go.
Or
You could simply download the Oreo fastboot ROM with the August security patch which is available at the moment but isn't the latest one as the latest October security patch rolled out to RETIN devices just a few days ago so I doubt that the full fastboot ROM would be available this early. But then again, if you flash the Oreo August patch, you can take the OTA to October patch and be just fine.
Note:
But a bit of advice, if you're planning to go back to Nougat using a Nougat fastboot ROM, I'd highly recommend the TWRP flashable as one can mess stuff up while trying to downgrade using a fastboot ROM as Moto phones have problems downgrading. It's all about these two partitions called "gpt" and "bootloader" which when not paying attention to while flashing can cause a hard-brick.
A safer approach would be to skip these two partitions while using a fastboot ROM to downgrade but I'd be honest and would suggest you to wait to be sure this would work as I myself haven't tried this while downgrading from one Android version to another as Oreo bought with itself some Modem and a few other changes in partitions as compared to Nougat.
If I were you, I would wait for some to confirm the part in the "Note" just to be absolutely sure that it'd work.
Thanks for the response
Thanks for your response.
I'll be going with your suggestion and flash the twrp flashable oreo.

You could simply download the Oreo fastboot ROM with the August security patch which is available at the moment but isn't the latest one as the latest October security patch rolled out to RETIN devices just a few days ago so I doubt that the full fastboot ROM would be available this early. But then again, if you flash the Oreo August patch, you can take the OTA to October patch and be just fine.
Note:
But a bit of advice, if you're planning to go back to Nougat using a Nougat fastboot ROM, I'd highly recommend the TWRP flashable as one can mess stuff up while trying to downgrade using a fastboot ROM as Moto phones have problems downgrading. It's all about these two partitions called "gpt" and "bootloader" which when not paying attention to while flashing can cause a hard-brick.
A safer approach would be to skip these two partitions while using a fastboot ROM to downgrade but I'd be honest and would suggest you to wait to be sure this would work as I myself haven't tried this while downgrading from one Android version to another as Oreo bought with itself some Modem and a few other changes in partitions as compared to Nougat.
If I were you, I would wait for some to confirm the part in the "Note" just to be absolutely sure that it'd work.

I'm having Moto g5 plus Indian variant xt1686. I have installed a custom ROM Resurrection remix and I'm currently running it.I want to get back to stock rom. I went through many existing threads only to get myself confused. I want you guys to help me get back to stock ROM so that I can get OTA updates.
1. I have working volte and IMEI till now. I didn't take back-up of persist or efs as I was lacking knowledge. Can I take back-up of those now for going back to stock. If yes then suggest how?
2. I don't remember my build number from which I unlocked my bootloader. Should I lock the bootloader again to get OTA? If not then please suggest any way to get back to stock whether Oreo or nougat (get updates to Oreo then).

Hello LG fans,
There is an old thread with a similar title, but since it is inactive I started this one. For certain reasons I got this G4 phone only few days ago. The model number on the box and under-battery tag as well as in settings showed F500 (just F500 without any suffix S, L, or K). It came with Android 5.1, and everything was working well. Online search showed that F500X phones can be officially updated to Nougat 7.0, but the phone OTA update said no update was available.
As per LG website, I installed LG Bridge to get the updates. It identified the phone as F500K and found two updates. First it installed 6.0 Marshmallow and then 7.0 Nougat software version F500K30c. Also the model no changed to F500K in settings. I think this probably means it is is a refurbished phone
The Installation was successful, but it installed a Korea Telecom version with some Korean stuff. I uninstalled or disabled all the Korean bloat I could without root, but there are still a few things remaining, and some Korean language here and there.
In general, I’m quite satisfied with the phone. The only thing I wish to get rid of is the KT Wifi manager app which is all in Korean, and I don’t know what it does or which settings to select. It is a system app, and I can’t uninstall or disable it, but my wifi and data networks seem to be working fine, so no complaints. I’ve seen several people here and elsewhere complaining about network issues, boot loops and bricks, but so far I haven’t experienced any. I hope it stays this way :fingers-crossed:
I was wondering about the other variants F500S and F500L, do they also have Korean bloat and is it more or less than F500K? I have read somewhere that these three firmware variants can be interchangeably installed. Is this the case, and if so, is it advisable to install another variant? I have been reading about this phone, but this is my first time to use an LG phones, and I have no experience with their software and tools, so any help, ideas or suggestions will be highly appreciated.
Thanks

You could
downgrade to MM,
backup with SALT (CRUCIAL important),
unlock by UsU ,
extract with SALT: system ,modem and boot partitions from a f500 kdz,
root and debloat or (if you like to) install a custom ROM
Check the UsU and SALT threads (you can find both in my signature)

Thank you @steadfasterX for your reply,
It's quite an honor the Guru himself was the first to reply to my post. I have seen many of your posts and replies in the forum before, and now looked at some of the stuff in your signature. Pretty impressive work. I definitely need to spend some time learning about them particularly SALT and FWUL, as I have also started learning and using Linux lately. How come FWUL is not shown on distrowatch?
For the time being, I was thinking to stick to stock Nougat 7.0 as it's a fairly recent OS, and the phone is fine even with the remaining little Korean stuff. My main dissatisfaction really is with the mysterious kt wifi manager app which is all in Korean and has some settings which I don't know what they are. If just replacing the current Nougat 7.0 with another variant S or L is actually possible, and these variants don't have a similar app, this would be great.
I have been searching for information about these S/L/K firmware variant differences but couldn't find much. I hope other S & L phone owners could tell us about their phones. The only thing I could find so far is that each is for a different carrier in Korea, and that they can be interchangeably installed as per a Reddit post. I don't know how reliable this information is!
From a purely technical perspective for G4 F500 , is it possible to flash another F500 variant using LGUP, or is this something that shouldn't be done? I have seen many people getting in trouble for flashing wrong firmware. If this is safe to do, do I need to do any preparation work like downgrading to MM first, and should this be done as an upgrade or a refurbish? For what it's worth, my ARB value is 0.
Thanks

Hi Sfx,
1. to downgrade to MM... use uppercut, right? I'm using latest 20u for F500l is OK for UsU?
2. after backing up with SALT, can I revert back anytime after unlock and with new custom ROM?
3. after rooting, do I install twrp and load custom ROM? and can I extract 30b Nougat's modem from KDZ to use with the custom ROM?
thanks so much in advance for answering...:angel:

Because they are ignorant and/or just arrogant enough to ignore my requests. I even offered to pay advertisements as this should be (according to their website) a way to get listed instant. but nothing. Even not on the waiting list..

ok so one thing first. the most important one: Ensure you keep your ARB at 0. This is crucial important. So never ever flash anything (including QFIL restore files!!!) where you are not 10000% sure it wouldn't increase your ARB.
If you are about to flash a KDZ then check that file with SALT first (simply press extract and it will display the ARB). If you flash anything else.. well ensure that the files offered have that information listed and hope and pray its not wrong (e.g. there are QFIL files around which are labeled for a ARB 0 model but contain ARB2 files..). Never heard about a wrong labeled KDZ file but who knows.
The second important thing is (maybe its even the first): before doing anything, do a full backup with SALT (basic is fine) and (!!) move that to a secure place! (I saw so many ppl who lost their backup through several ways).
So when going on through the UsU process you will have 2 SALT backups: the one before downgrading to MM and another one after you downgraded to MM (tbh the more important one). If you can keep them both.
so about flashing other variants: yes it IS technically possible to even flash e.g. h815 ROMs to a F500 and so converting it that way! but never try that with h811 KDZs or others..
anyways yea you could flash other F500 variants without fear (just carrier bloat is different) as long as you follow the above advises.

1. I dunno the latest MM F500 version but "20u" sounds good. Can't help in the downgrade process but there are plenty of guides here in the G4 forums.
2. dunno that you mean here.. but if you wanna know if you can stay on STOCK after UsU'ing yea sure. flashing UsU does not require to go for a custom ROM. It just gives you the freedom to do so.
3. if you follow the UsU guide you will have TWRP already and that's the place where you install a custom ROM if you like. Sure extract the 30b modem and flash it in fastboot should work fine (after UsU).

Thanks sfx, I'm now on MM and ready to get SALTed I want to flash AEX v6.7 But there are two offerings H811 and H815, and my F500L in SALT say GPT compatibility is H811 /ARB0, so do I flash H811 version of AEX?? If so, is there a H811_UsU_baseband_flash-in-twrp I need to flash as well? thz

if you would flash h811 on yours you will increase your ARB so do NOT flash that.
Use a h815 based ROM even when SALT compat shows different. your partition layout is somehow weird..
for non-UsU ROMs flash the f500(!!) baseband package once

Hello, I apologize for the noobish question in advance.
I don't have an LG V20 myself, my friend has one and wants to unlock the bootloader. Normally Verizon devices are NOT bootloader unlockable but when I looked on this site (could be fake but who knows till they ask) it appears the Verizon variant of the LG V20 is in fact unlockable. As someone who is unfortunately very familiar with Verizon variants of phones, this is unusual news to me. Usually Verizon locks their stuff down with no hope of unlocking.
Anyway, just wanted to ask if that site's guide was correct for how to unlock the bootloader on the LG VS995 variant from Verizon. His Android version is 8.0.0, build number OPR1.170623.032. Software version VS99520c. Security patch October 1st, 2018. Security software version MDF v2.0 Release 4. Do I need to downgrade the firmware at all or can I just do it?
Any help would be greatly appreciated. He wants LineageOS on that thing (to get the latest security patches) and I don't blame him.
It's not that easy unfortunately.
The first thing that would need to be done is to revert the phone back to Nougat 12a or 13a. I have not done this part (both my VS995 were on some version of Nogat, I reverted the version to 12a by flashing the kdz), but guides are available to revert to Nogat from Oreo on XDA in the
https://forum.xda-developers.com/v20/
Section.
Then what is on that site would most likely work. I would suggest using this guide instead as I have rooted two VS995 with it. It is less confusing that the Dirty Santa or Dirty Elf guides IMHO, but it is later and builds on those guides.
https://forum.xda-developers.com/v20/how-to/guide-root-twrp-lg-v20-using-dirtysanta-t3722278.
Good luck, although if you plan to use the phone on Verizon, it's only a matter of time before a stock ROM with VoLTE is a requirement for using the phone. I guess he can switch back at that point (or go to one of the GSM providers).

Just to clarify this isn't just a root this is a full on bootloader unlock right? I assume it is because TWRP gets flashed, but then again there were custom recoveries in the past that were just Safestrap and weren't full on recoveries (still locked BLs). Because the end goal here is to install Lineage or something like that to the phone. I'm not interested in just rooting stock.
Also, wasn't aware about the stock ROM requirement thing for Verizon, I thought it was only VoLTE they were implementing. That's a bummer. Thanks for the heads up
