AWESOME job, everyone! Thanks so much for this-- I admit I may wait a little while for feedback before trying my own unit, but given that I jumped on the V20 early in hopes that if any version is hacked it'll be the earliest firmwares, I can't imagine it'll be too long before I'm back to enjoying my phone the way I like it!

Definitely will be sending some coffee money along, even though I wasn't in any of the bounties...

Damn I've been waiting for this soooo much but there's only thing. I don't now crap about LG phones I've been a Sammy fanboy for 7 years lol. Guess I'll have to wait till my boy can do it.

to be honest theres nothing really lg specific besides the files themselves lol.. of course you never use Odin outside of Samsung lol..

majority of it is pc bat or adb commands and then you got your typical twrp stuff but hey, best to have your buddy do it if youre not comfortable :)

Hey guys I need a little help, last step I was able to complete was running "Step3.sh, after reboot I'm unable to get into recovery mode. does anyone know the manual steps to get to recovery mode?

I also continue to get the popup "com.android.phone" has stopped.

No mobile service

I'm assuming you're on Mac/Linux. If so, in terminal verify connection with "adb devices". If you're connected fine, enter "adb reboot recovery"

Well in that case, you probably should have executed the ".bat" not the ".sh"

I'm running Windows 10, and successfully followed the guide. My device is past boot currently, and is installing apps from a Google backup.

This version of adb is portable. Wherever you extract it is where it is 'installed'. You need the required files to be in the same folder as those files. Can you send me images of what you are trying to do in PM please.

Thanks to the team for this.

For anyone encountering issues I am more then happy to help, I have 10 LG V20 all att, on a huge group plan that I just did this for all of them. Patience, read through directions 10x make sure adb anywhere is installed, know the difference between adb and bootloader commands and you are good. I don't have as much time at work to check the thread, but can answer PM's on the fly if any help is needed. Thanks again to this community.

Is anyone having issues with youtube. I'm getting play back errors
[LG V20 Guides, News, & Discussion] AthieN:
I can confirm that comfort view does not work. However, I don't use it anyway because LG has surprisingly good themeing capabilities! Have you tried using a different theme by chance? The built-in high contrast one is nice. I am using a paid theme called Remix (available on the Play Store for $2) that gives it a really nice dark look. :)
[LG V20 Guides, News, & Discussion] elliwigy:
go into app settings and uninstall updates.. then go into play store and disable auto update for youtube.. for some reaon it doesnt play on updated youtube apk so its a temp fix until we find a full fix
[LG V20 Guides, News, & Discussion] Datblkbro:
By any chance u know the version we have running by default. I removed the original youtube app from system.. R do u have a apk for it

Anyone post the version of youtube for me. I found a list of old apk just dont know which one to use

Anyone know why it's saying untrusted app in the id on the terminal
[LG V20 Guides, News, & Discussion] Matt07211:
A full one click root won't happen. Why? Becise some of the stuff needs to happen when you not booted into the OS (E.g.Bootloader, TWRP), but up untill booting into the bootloader for the first time can be done by an app.But really it doesn't cut much of the steps at all.

If you've read the thread/instructions you aoul realise that this is needed to be like that. The reaskn why its labeled untrusted is so to Selinux (I suggest you Google it if you want to learn more)

[LG V20 Guides, News, & Discussion] Chaz187:
Google search is your friend! I just did a search and it pops up!

Sent from my Ls997 using Classic Rom!
[LG V20 Guides, News, & Discussion] jimbosi:
Well, I bricked it (VS995). Got stuck between step 2 and step 3, where the handset constantly vibrates. I can get into download mode, but recovery just presents a messed up screen.

Now not sure I had the required files in the right directory (Win 10). I have an adb folder with fastboot in it. TWRP goes in there?

Are there any steps I can follow by going to download mode and performing whatever unbricking steps I can do?

I just got the handset yesterday, so I can still return it (14 days), but if I can recover it, I'd rather do that.

Any hints? Tks!
[LG V20 Guides, News, & Discussion] nighthammer:
Well, carp

So, I followed the steps and got stuck in a bootloop when rebooting from fast boot. I later found that my computer didn't copy over the TWRP file and now the phone will not boot and I can't get the PC to see the phone. Is there ANYTHING I can do to recover from this? Please God tell me there is....

question? are both adb folder and active adb folder the same folder??
[LG V20 Guides, News, & Discussion] jimbosi:
twrp

Same here--can get to TWRP now. Attempting to boot into system. Staring at Verizon screen.

"5) During reboot you will get a Red Triangle with a "!" inside, this is normal (First boot after flashing SuperSu will show the Red triangle twice.Wait for system to boot (this will take awhile). It may appear like the system has frozen but it has not. JUST WAIT!"

I wonder how long this actually is before I should try something else?

Okay I got my phone finally to boot up but now I'm getting the fuzzy screen now
[LG V20 Guides, News, & Discussion] jerrycoffman45:
fuzzy screen ls normal let the screen time out put your finger over the sensor by the front camera till the secondary screen goes off then turn the screen back on you have to do that each reboot
[LG V20 Guides, News, & Discussion] astonmartin214:
got it
[LG V20 Guides, News, & Discussion] jimbosi:
Hmm--my memory is a bit hazy, but I may have done a factory reset out of habit (I've flashed on Galaxy devices hundreds of times). Where is the bootbackup.img, because I get "error: cannot determine image for 'bootloader.img'"?

I'm sure this is recoverable somehow because I have TWRP successfully installed. On boot, it just goes back to TWRP, however.

Also, I get a "system corrupt" with red triangle/exclamation. Is that bad?
[LG V20 Guides, News, & Discussion] jerrycoffman45:
if it is on the setup wizard just turn the screen off with the power button
[LG V20 Guides, News, & Discussion] 315phatboi:
ok now im stuck at at&t logo..... what should I do now..... been on at&t logo for about ten minutes maybe more??
[LG V20 Guides, News, & Discussion] astonmartin214:
thanks I got it fully working okay where is a Pure Nexus ROM for the V20 meaning a stock ROM that's extremely debloated just with the basic apps
[LG V20 Guides, News, & Discussion] jerrycoffman45:
depends on your model i use weta
[LG V20 Guides, News, & Discussion] me2151:
Yea you did a factory reset. So you are on a twrp loop. The directions to fix are around somewhere. Just search for that. The bootbackup.img is located in the folder with all of the .bat files.
[LG V20 Guides, News, & Discussion] 315phatboi:
should i just pull the battery?..... now its going on half an hour its stuck at the at&t logo?
[LG V20 Guides, News, & Discussion] jimbosi:
Rats. The only .img files in the "Required Files" are aboot.img, boot1.img, and boot2.img. I'll poke around for "TWRP bootloop." Hope I can get things fixed. Let me know if there is something else I should do. Tks!
[LG V20 Guides, News, & Discussion] me2151:
You can look in the /sdcard/ folder and see if they are there. It should have automatically backed up though if you followed the steps
[LG V20 Guides, News, & Discussion] 315phatboi:
still stuck on just the att logo wont go pass at all in have tried to redo the all the steps but nothing still stuck.... even pulled the battery and tried to but into recovery with the buttons but still nothing just gets to the att logo and wont go into os...... can some one please tell me what I should do next??
[LG V20 Guides, News, & Discussion] jimbosi:
Is bootbackup.img a file that's dynamically created? There is nothing in /sdcard except a TWRP folder, which contains one file: .twrps. The solution to TWRP bootlooping is in this thread:

https://xdaforums.com/v20/how-to/how-to-fix-twrp-bootloop-t3513580

So the first thing is install proper TWRP. There is no version for VS995.

These directions from [MENTION=7113878]Mrsana[/MENTION]:

"Turn off your phone. Go into TWRP *manually*. That is, press the power off and volume down buttons. Once you see the LG logo, quickly release the power button and press it again. It will ask if you want to do a factory reset. Say "Yes" to both.

"Once inside TWRP (*manually*), do a factory reset. You will be rebooted and it will go back to TWRP. Once inside TWRP after the reboot, go to reboot and choose "System". You should know be out of the TWRP bootloop!

"It worked for me."

The Corrupt Triangle comes up far too quickly to do button presses. I've done Factory Resets, which go against your directions.

In the Required Files, here is a complete file list:

aboot.img

boot1.img

boot2.img

dirtycow

dirtysanta

my-run-as

Runmefirst.bat

Runmefirst.sh

Step1.bat

Step1.sh

Step2.bat

Step2.sh

Step3.bat

Step3.sh

bootbackup.img--is that a kernel?

I even went to this page http://www.tipsntricksbd.cf/2017/02/how-to-root-lg-v20-at.html, which seems to be a how-to in accordance with your own directions, and it mentions bootbackup.img in step 31. It's not clear where that file comes from.

So I guess I'm stuck. Anyone who's recovered from this, please let me know. Tks!
[LG V20 Guides, News, & Discussion] me2151:
Bootbackup.img is the original boot image. So yes the stock kernel. It IS a universal file so you can use one from someone elses phone ONLY if they are using the same version. Those are not my directions btw. They literally copy and pasted someone elses instructions.
[LG V20 Guides, News, & Discussion] jimbosi:
ROM install

.

Fair enough. I'll endeavor to find it. In the meantime, can I just flash another ROM from TWRP? I mean, I'm already boot(loop)ing into it, so I guess I could try it. If I can't get it figured out, I suppose I'll have to return the handset (within 14 day period). I'll have to think carefully before attempting again. That said, I'd rather have root. Tks again!
[LG V20 Guides, News, & Discussion] me2151:
Yes you can just flash another rom. They usually have their own kernel. Keep in mind you will still twrp loop until you follow the steps to fix it. The sprint not to stock rom thread has the steps on post #3 i think.
[LG V20 Guides, News, & Discussion] astonmartin214:
I'm on VS996
[LG V20 Guides, News, & Discussion] me2151:
No such phone :)
[LG V20 Guides, News, & Discussion] astonmartin214:
o hush u knew what I meant man I just got the phone us996
[LG V20 Guides, News, & Discussion] me2151:
Actually i didnt know lol. There is the vs995 or us996 so you combined them by accident lol. And to be completely honest the us996 is an unsupported model for this method. Yes it may work but i havent done any testing with it. What exactly are you stuck on right now?
[LG V20 Guides, News, & Discussion] jimbosi:
[MENTION=5619709]Swizzle82[/MENTION] says, "You need to boot into twrp via hardware keys then factory reset. I did this a while back. It was frickin killing me. You need to power off or pull battery. Use the hardware keys(power plus volume down until lg logo appears then release power for one second repress it until you get the white reset screen) to boot into recovery. Hit yes twice. Factory reset. Restore your backup if you have one the reboot system.."

Do those instructions sound familiar?

If I may ask, what exactly did I screw up, and what is the above procedure correcting? And are there any alternatives to this? The precision timing is exasperating. At any rate, tks for the guidance.
[LG V20 Guides, News, & Discussion] astonmartin214:
O nothing now I got it booted it & running just wanting a debloated stock ROM that's all now
[LG V20 Guides, News, & Discussion] me2151:
Those are the steps but you dont need to restore a backup. Just go to reboot after you boot using the hw keys method. You HAVE to go through the white screen. Where you went wrong was just the factory reset in twrp. It will 100% of the time cause the twrp loop. The above procedure clears out some screwed up twrp settings from the misc partition. Allows it to boot properly afterward.
[LG V20 Guides, News, & Discussion] me2151:
Oh. The us996 has a debloated stock rom somewhere. You will have to look for it though. I dont know where it is.
[LG V20 Guides, News, & Discussion] astonmartin214:
but when you run the Weta installer it has vs996 as an option to flash but it says unlocked
[LG V20 Guides, News, & Discussion] me2151:
They might have a typo if it says vs996. But the us996 is the unlocked model.
[LG V20 Guides, News, & Discussion] jimbosi:
OK. It's a tough nut to crack because the LG splash screen is up for less than .25 of a second. From there it goes to "corrupt system." I never see a white screen, just the LG screen.

There wouldn't be any way of going into TWRP's file manager and deleting the file from there, would there?

At any rate, I greatly appreciate all your help!
[LG V20 Guides, News, & Discussion] me2151:
Nonono its not doing it right if the lg screen is only there for .25 second. Are you pressing vol- or power first?

If done right it should show LG for like 2-4 full seconds before showing corrupt screen
[LG V20 Guides, News, & Discussion] jimbosi:
Holding Vol- down, then hitting power. Maybe I've done something else wrong. Wouldn't surprise me.

How about reinstalling TWRP from download mode or installing over itself in recovery?
[LG V20 Guides, News, & Discussion] me2151:
Wont fix it. Still would need to go through the white screen to work. WAIT are you HOLDING power or just hitting it?
[LG V20 Guides, News, & Discussion] jimbosi:
Holding Vol- then holding power until the screen begins to display. Is that the right way? Just did it with the power cord and I boot into recovery. I'm an idiot. Stand by.
[LG V20 Guides, News, & Discussion] me2151:
Try to continue holding power even after the screen displays. See if the lg logo stays longer
[LG V20 Guides, News, & Discussion] astonmartin214:
I mean the us996 gotta get use to putting us instead of vz
[LG V20 Guides, News, & Discussion] jimbosi:
LG logo stays a bit longer, but never becomes a white screen. Kicks right to Triangle. Any timing hints on keying Vol- during this time?
[LG V20 Guides, News, & Discussion] me2151:
Ok heres what i want you to do. Hold vol- and power and when you see lg wait half a second then let go of power only and then hold power again( should not let go of vol- at all.)
[LG V20 Guides, News, & Discussion] jimbosi:
Sweet! "Do you want to delete data?" Yes! (twice).

Still Red Triangle, then TWRP. Factory reset from there now?
[LG V20 Guides, News, & Discussion] me2151:
No
[LG V20 Guides, News, & Discussion] me2151:
You do yes twice. When in twrp JUST. Go to reboot then system. NEVERNEVERNEVER factory reset from twrp(once again lol)

And you will always get the red triangle. Your phone isnt stock. Thats why it shows that
[LG V20 Guides, News, & Discussion] jimbosi:
Now can I reboot into system? Afraid to do anything.
[LG V20 Guides, News, & Discussion] me2151:
Yes you can reboot to system now. If you still have not flashed supersu you still need to do this
[LG V20 Guides, News, & Discussion] jimbosi:
SUCCESS!

So the definitive solution to a TWRP bootloop (courtesy of [MENTION=997457]m21[/MENTION]51) is this:

Power off

Press and hold Vol-

Press and hold Power

LG logo appears

Release Power for 1/2 second, then re-hold

When white screen ("do you want to erase data"") appears, Release power

Red Triangle "system corrupt" appears

Boots into TWRP

nevernevernever(!) Factory Reset

(if ROM is loaded), Reboot System

Screen may still display "corrupt system," but will eventually boot

Profit!

Since we can't Factory Reset, how do we install new ROMs? Which partitions to delete? TKS AGAIN [MENTION=4591212]me2151[/MENTION]!
[LG V20 Guides, News, & Discussion] me2151:
You can still go to wipe->advanced then wipe cache data and dalvik and thats basically a factory reset.
[LG V20 Guides, News, & Discussion] TheIronMaiden:
I've been here since the skyrocket, but it was simple to root that, even ported ROMs, but when I try to root this, I'd write the 1st "sh" code into the terminal and it says command not found, and I'm getting pissed. Windows 10 64 bit ATT version
[LG V20 Guides, News, & Discussion] me2151:
... This is a joke right? Im not trying to be rude or anything but did you even read the guide?

Edit: i do actually see you are not a new user so im going to asume you are just having a brainfart and ill answer your problem for you. If you read the guide you will see you are following the mac/linux instructions. Windows doesnt use .sh files thats why you get an error. Use the batch files on windows(.bat)
[LG V20 Guides, News, & Discussion] TheIronMaiden:
i had a brain fart, I did all the steps, able to go to step 3, and now my phone is stuck on the att logo, is it supposed to take a long ass time to boot?
[LG V20 Guides, News, & Discussion] me2151:
Check if your phone is showing in your adb list. If it says offline then pull your battery and start the phone back up then spam adb reboot recovery until the phone restarts
[LG V20 Guides, News, & Discussion] TheIronMaiden:
backing up the phone now, I paniced at first, and then I reviewed the guide again, thanks for your patience
[LG V20 Guides, News, & Discussion] me2151:
Np. Do keep in mind you cannot backup data partition as its encrypted and the phone needs to be decrypted before you can root. It will cause issues if you try to use your data backup
[LG V20 Guides, News, & Discussion] TheIronMaiden:
its been 15 minutes, still on the att logo...do I need to flash a ROM? lol I'm impatient
[LG V20 Guides, News, & Discussion] me2151:
Have you flashed your bootbackup.img back yet? It wont fully boot with the boot1.img
[LG V20 Guides, News, & Discussion] TheIronMaiden:
it didn't finish, daughter touched a button, what should I do lol
[LG V20 Guides, News, & Discussion] me2151:
Just boot bootloader(pull battery and reinsert so its powered off) then hold vol- and plug it in. It will boot the bootloader. Once the bootloader is open flash the bootbackup image by typing fastboot flash boot bootbackup.img from a command prompt in your working directory. Then reboot
[LG V20 Guides, News, & Discussion] TheIronMaiden:
in the middle of the backup my daughter fooled around with it and it didn't back up completely theres no back up to be found
[LG V20 Guides, News, & Discussion] me2151:
Look on the computer in the folder where you had the .bat files. Should be there called bootbackup.img
[LG V20 Guides, News, & Discussion] Chaz187:
Then you will have to flash a att rom....
[LG V20 Guides, News, & Discussion] TheIronMaiden:
it said boot cant be found

---------- Post added at 09:02 PM ---------- Previous post was at 09:01 PM ----------

that's what I thought, usually the appropriate response when you accidentally erase the boot, and didn't back up...had many of those on the damn skyrocket lol
[LG V20 Guides, News, & Discussion] me2151:
Do you see the file on the computer?

Edit: as Chaz has stated you could just install an att rom. They will have their own boot.imgs. just install supersu afterward
