I own LG V20 AT&T variant on android 7, was thinking since couple of weeks to follow this to upgrade to Oreo as i was not satisfied with android 7. So yesterday, I followed the instructions from rooting to flashing oreo 20h rom, kernel, magisk etc...and the result is smooth and great performance on Oreo with TWRP recovery and root access without that annoying bootloader startup screen. Very well done and thanks for this easy to follow guide.

Just want to ask that....

If i intend to format/hard reset, should i do it from settings or from recovery. And....

After format/hard reset, i have to flash kernel, magisk again?

And last one is,

Is there any setting to modify the speaker volume values to increase its volume?

Thanks and regards.
[LG V20 Guides, News, & Discussion] clsA:
If you still have TWRP it's always best to Format Data / type yes / for a full wipe

anytime i format data I always reflash the kernel and magisk just to be safe.

I don't recall ever using a volume boost app, I'm sure their are plenty of them

did you try pulling the battery out ?
[LG V20 Guides, News, & Discussion] ezzony:
I'm having some issues I've explained in detail here

I just want to repeat one question here; Does anyone know or could you check *#LGMENU#*910# > Field_Test>ModemSettings...do you see the full range of menu options, maybe a dozen or so including Band Selection etc? On mine most of the options you'd expect to find are missing with only two remaining. I'm trying to find out if I've done something to bring this about as I have deleted some at&t stuff maybe one I shouldn't have.
[LG V20 Guides, News, & Discussion] ezzony:
^^ Changing ro.build.target_operator in build.prop to OPEN brought back all the missing Modem_Settings and the ones that were also missing in regular Settings>Mobile Networks. Also reverted to stock icons in status bar.

After installing the Oreo Rom Flash TWRP again or you will have to start over

After reboot recovery and flashing the Mk2000 kernel your done.

Skip all of that it isn't needed

The Rom actually includes Magisk but yes if you want to update it it's the last thing you flash in TWRP before your Done

[LG V20 Guides, News, & Discussion] RoboB:
Dear clsA, thank you so much. I was able to upgrade my H910 to Oreo after following your guide. Thank you again. :good:

These are the steps I followed and my V20 is still show that ugly pink and black (+ flickering) screen on boot (image attached).

[IMG="LG V20 flickering on boot"]https://imgur.com/a/frYnr99[/IMG]

Could you please guide me to get rid of this?

1. Followed the tutorial that you guided to follow in here

an rooted.

2. Followed this tutorial to hide bootloader warning.

3. Downloaded the file linked in here.

4. Open both downloaded Hide_warning-att.zip file and H910_20h_Oreo_full_rooted.zip from 7zip.

5. Drag raw_resources.bin from Hide_warning-att.zip and then dropped it in to the H910_20h_Oreo_full_rooted.zip (didn't do anything with META-INF folder. Because I don't know why it was there :silly:)

6. After 7zip finished its tasks rebooted V20 to TWRP.

7. Then Format Data > Installed edited H910_20h_Oreo_full_rooted.zip > Format Data > Installed H910_v1.0-mk2000 > Format Data > Installed twrp-h910-2019-05-17-3.3.1-0 > reboot

8. Then I got a boot time warning, but then booted to welcome.

What I want is to get rid from that ugly pink and black flickering screen on boot. Please help!

Thank you.

I do all and 6month is that stay in oreo h910 20h.

But during this 6month i have more crash(green screen

Crash).i do all thing that you say before for fix but

No fix.

I think kernel mk2000 for oreo h910 is not good

And have more crash.

I come back to h915 and do again dirtysanta root and

Flash h910 20h again but no fix crash.

I change all version mk2000 for oreo but no fix.

Recently anybody there is not that developed kernel

For oreo lgv20 h910.
[LG V20 Guides, News, & Discussion] clsA:
Sorry but it must be your phone

I have been using the 20h Rom and mk2000 kernel for almost a year and have never had the green screen kernel crash your having.

Note: I have 4 - H910 v20h

I listed my silver one on eBay this week

And two are in another city.

The only thing done to them was root

Flash 20h and kernel. We have replaced the batteries in all but one of them. And none of us have any kernel crash.

If you go back through this thread I think you'll see your the only person reporting this problem.
[LG V20 Guides, News, & Discussion] sheik124:
YES!

I've only seen the green kernel panic screen on two occasions.

1. A much older mk2000 build after I tweaked one too many CPU governor settings.

2. With two batteries that had really bad voltage sag.

What 2 means is that when your battery is at a lower charge level, usually below 60%, it will not be able to supply as much current as the phone requires. As a result, the voltage supplied will also dip below what the phone needs to run properly. It's basically the same thing as overclocking a desktop processor without giving it enough voltage and getting a blue screen of death.

Buy a new, GOOD battery. Don't waste your time with an "OEM" battery. They're all fake. Try and find a reputable 3rd party one. Not sure what kind of options you have.
[LG V20 Guides, News, & Discussion] dornz:
This one ?
[LG V20 Guides, News, & Discussion] supercommanderz:
Need post here my instruction to flash 20h oreo and keep work 4g/LTE:

1. Backup with patched LGUP this blocks:

misc

modemst1

modemst2

persist

persistent

modem

(this step very important step because in future you can lost 4g/LTE with other blocks)

in future you can write this blocks by command like in 3.step

2. Use command to get exploit:

git clone https://repo.or.cz/cve2019-2215-3.18.git

and commands get root:

adb push su98 /data/local/tmp

adb shell

cd /data/local/tmp

chmod 755 /data/local/tmp/su98

./su98

3. Write engeenering aboot from DirtySanta archive (to boot with not signed partition):

adb push aboot.img /storage/emulated/0/Download

dd if=/storage/emulated/0/Download/aboot.img of=/dev/block/bootdevice/by-name/aboot

Use commands to change LAF partition to recovery (because orig recovery we need in future):

first zeroing because size diferent:

dd if=/dev/zero of=/dev/block/bootdevice/by-name/laf

dd if=/dev/zero of=/dev/block/bootdevice/by-name/lafbak

dd if=/storage/emulated/0/Download/recovery-twrp-h910-2019-10-25.img of=/dev/block/bootdevice/by-name/laf

dd if=/storage/emulated/0/Download/recovery-twrp-h910-2019-10-25.img of=/dev/block/bootdevice/by-name/lafbak

Now you can enter to TWRP recovery:

1. Power off you device

2. Press UP VOL and connect usb type-c cable

3. You boot in TWRP recovery

4. In TWRP recovery:

Go to Wipe:

1. Wipe all except internal storage

2. Format data: yes

5. Go to install and install H910_20g_Oreo_full_rooted.zip

and wipe cache/delvik with swipe

6. Go to install and install H910_20h_Oreo_full_rooted.zip

and wipe cache/delvik with swipe

7. Also Install kernel mk2000 ver 2.2 from this link:

https://androidfilehost.com/?w=files&flid=297449

H910_v2.2-mk2000.zip from Aug 03, 2019

if bad kernel you can see green or black or purple screen of death

so reinstall kernels until you be free from screens of death

8. Go to wipe:

1. Wipe cache and delvik cache,

2. Format data and type yes.

(format data need to be free some potencial TWRP code/decode errors)

9. Connect to PC and repeat step 3, because laf section can be rewrited in 5.6. steps.

Aboot can be untooched in 5.6. step so no need rewrite aboot.

10. And now you can reboot:

1.Select Reboot and select Reboot to Recovery

( you boot original recovery, not TWRP.)

10. In orig recovery in dialog twice select YES, YES to clear data and fresh boot to os.

11. It's all - boot to os and restore original blocks backuped in 1.step to get 4g/LTE work (if you write some 915kdz and so on who kill you orig modem)

Also you need install MagiskManager-v6.0.1.apk to get root work with already patched Magisk in H910_20h_Oreo_full_rooted.zip

Or patch in TWRP to Magisk v20.1 and use MagiskManager 7.4

And don't forget write APN in you modem settings on device.
[LG V20 Guides, News, & Discussion] Merazomo:
H910_20h has to be clean flashed correct? No way of dirty flashing as to no start over from scratch; I'm talking about settings and stuff like that. I'm on H910_20g I believe. Does it matter at this point though? having H910_20h over H910_20g?
[LG V20 Guides, News, & Discussion] Phoenix591:
Why? Stock recovery is useless except for just wiping your data and applying otas. And applying otas won't work when rooted (otas depend on things not being modified from stock which rooting does). (If you're concerned about encryption my latest twrp can actually work while encrypted or twrp 3.1.* doesn't have the glitch when formatting data)

Also you don't need to zero it, it's smart and stops at the end of twrp.

Lastly all of the *Bak partitions, lafbak included, don't actually do anything.
[LG V20 Guides, News, & Discussion] supercommanderz:

[LG V20 Guides, News, & Discussion] partyman66:
I've been using this ROM pretty much from the first week that the stock Oreo rooted 20h came out and with MK2000. My phone runs great in general except that idle drain is poor. I have my phone customized to hell so it basically sleeps 99.9% of the time when the screen is off, yet even in airplane mode I lose about 2% battery per hour (using a fresh Perfine LIPO 4100 battery). I've tried with 2 other batteries and it does the same. I can only assume either my hardware is defective or the Kernel is doing something to piss through battery. I do have quite a few kernel wakelocks going on according to BetterBatteryStats and a ton of errors show up in my log which are presumably kernel related.

My question is does H910_20h_Oreo_full_rooted.zip work with the kernel that comes with it, or do you need to use MK2000 to have a fully working rooted Oreo with this ROM? I was thinking of trying to go back and run the stock kernel with my system to see if battery life is affected in any way.
[LG V20 Guides, News, & Discussion] clsA:
If I remember correctly the stock boot.img is in the rom. It just doesn't get flashed.

If not it's in my AFH

You will have static on boot up and have to cycle the screen off and back on to get past it

[LG V20 Guides, News, & Discussion] partyman66:
Thanks for replying.

I ended up booting into TWRP and creating a whole backup of my phone, installing the original ROM that I used to build mine from, and then without rebooting out of TWRP I installed the backup that I had just created but unchecked the BOOT partition. Reinstalled TWRP from the recovery Image just in case and then rebooted the phone and it's all good now. This successfully reverted my existing phone image to the stock\Non-MK2000 Kernel. Everything works fine except that I now have to deal with the annoyance of screen retention.

I'm looking into building my own kernel for this thing based off of stock if I can get my development environment to successfully compile the original LG Kernel code.

Question on the process for oreo for the 910 20..

I have the recovery twrp-3.2.3-0-h910.img installed.

I folllowed the steps and installed:

H910_20h_Oreo_full_rooted.zip and added zips for H910_v1.0-mk2000.zip and what i thought i needed, SR5-SuperSU-v2.78-SR5-20161130091551.zip but now realize supersu is outdated, so at this point only mk2000 is on there.

The phone appears to be up to date and on oreo. Initially the free root checker seemed to say it wasnt rooted, but on second run it show it is.

I tried to run magisk manager but it says unfortunately magisk manager has stopped. (edit possibly related to the fact i didnt add any magisk 17.2 as a zip to flash, actually unsure where this file is located? can i do this now after the fact or does it matter)?

So at this point i think i missed something, maybe not fully rooted?

Questions are: does it matter if its not rooted? Will certain oreo features not work? Or, is this some isolated issue with just the manager not wanting to run?

The OS shows 8.0.0 (so i guess not 8.1), software version h91020h

*i also tried to do volume up plus power did the factory wipe, but the twrp menu no longer appears, it just formats things back to stock 8.0 welcome

The rom overwrite TWRP with stock recovery. Did you follow the instructions to flash the mk2000 kernel and TWRP?
[LG V20 Guides, News, & Discussion] tarpaga:
As I learned here, green screen is due to modems issues.

After installation, I couldn't get network signal so I did

fastboot flash modem modem.img

with my dumped modem file from LGUP

Now I get network signal but lost fingerprint :(
[LG V20 Guides, News, & Discussion] tarpaga:
No Nougat kdz for H910.

The modem that comes with the zip in OP lets the fingerprint work but no network signal :(.

Flashing the Nougat modem I dumped with LGUP brings back network but fingerprint is lost.

Any help will be greatly appreciated ?
[LG V20 Guides, News, & Discussion] clsA:
do you have an ATT Sim ?

you can flash the stock 20G rom and get the OTA to 20H

this would update all your modem files together.

modemst1 and modemst2, fsc contain your IMEI and cannot be flashed on other devices

this is why their not flashed with the Rom

All the files in the Rom are from ATT, and dumped with LGUP after the OTA update is installed

Only changes made by me are the eng aboot and the patched_boot.img

if you look inside the rom I actually left the original files in their too (they just don't get flashed)

Also All my Roms for the V20 overwrite TWRP with stock recovery

Be sure you flash TWRP after any Rom or you'll be back to square one
[LG V20 Guides, News, & Discussion] tarpaga:
Nope, I don't live in the US...

Not having/using an AT&T SIM won't let me get the OTA as I read here.

Thanks for these valuable informations ?

I think I'll put an end to my quest here without the fingerprint.

Thanks again for all ?

[LG V20 Guides, News, & Discussion] bitbang3r:
(update: when I tried it now, it found a mirror. downloading it now.)

Does paying for membership guarantee that it'll find a mirror with "H910_20h_Oreo_full_rooted.zip"? I keep getting "Oops! No mirrors found!".

I don't care about spending $1.99, but I'll be pissed if I pay it and it still can't find any mirrors with the file. If it just queued me up behind 400 other people, or limited the download speed to 1kbps, I'd just go ahead and pay... but that particular error message doesn't exactly give me confidence that paying actually WILL solve the problem...

[LG V20 Guides, News, & Discussion] neptunej:
Had this problem and figured it out. You have a F800 device made as H910. Flashing the rom in the OP will get you fingerprint but no modem. All you can do to restore both fingerprint and modem is to fastbook modem1 and modem2 from F800 stock rom and you'd have both network and fingerprint. Tried same method on 5 devices with same issue and had success on them all

Ok , so dirtyflashed over 7.0 rooted nougat & after reboot static screen on some bits until boot and then you can sign in but if remove battery & power up again you would have to sign in to google again:

Fix: had to push recovery with adb on Kali and then rebooted to recovery & flashed kernel which fixed all static & after that just a case of rebooting to twrp & flash migisk root zip :good:

I think kernel mk2000 for h910 at&t no work good for oreo.

I have for 1yaer green and purple screen crash.

I try any thing for fix but no fix.
[LG V20 Guides, News, & Discussion] rodogg88:
good night all. I installed this rom into my h-910 maybe a year ago and it worked fine until i installed an update to magisk that threw a soft-brick (showed a lg crash screen). After reading some messages online, I went ahead and flashed the rom again and got the phone working. after installing a new version of magisk, the soft-brick came back. I one again reflashed the rom and since I didnt add anything to the phone, no loss for the second flash.

after flashing the phone and installing a stable magisk, i started to add my info back to the phone. I started noticing that some apps on my phone flicker black and white whenever i open them. not the entire app, just parts of it like the top of the app etc. it happens with a handful of apps and i notice doesnt really affect me using them.

recently, i noticed that the usb connection menu pops up and defaults to charging another device aka use your phone as a power bank. I dont know if its related. the LG theme app seems to crash when i am downloading a theme.

does anyone have any idea whats going on with my phone? if i need to get a new phone or flash the rom again? thanks

also, whats does the mk kernel do?

The rooted rom H910_20h_Oreo_full_rooted.zip includes all the files of the stock rom

all you have to do is open the zip in winrar / 7zip

rename the current aboot to aboot.rooted

and boot to boot.rooted

and rename the 2 changed files they will likely be named aboot-copy to aboot

and v20h_stock_boot.img to boot

save the zip and flash it you now have stock 20H

If you can still boot to TWRP you can flash the rom again or flash the backup

If you have lost TWRP you have to start at the beginning and re install the eng Aboot with dirty santa
