FYI I'm on Sprint if it makes a difference

Got it fixed...was waiting for the phone to boot up and showing a lock screen as it stated here. 2) After you're rebooted, and back at the main lockscreen, type;

When on the LG screen i entered in adb reboot recovery and got to the next step.

above link is photo about booting error

my phone is ls997 (sprint)

after step 3

my phone can't boot

just boot to twrp

after install Stock_LS997_Full.zip with twrp

my phone also can't boot

How to recover my phone
[LG V20 Guides, News, & Discussion] solson20:
did you flash SuperSU after flashing Stock_LS997?

Also, when you go to whipe the device in TWRP, when selecting wipe, there is FORMAT DATA at the bottom prior to hitting advanced wipe.

Do you get to the static looking screen? Looks like a TV with no signal

Sooo I finally fixed my crashing issues... Root explorer would crash on me and my file explorer app couldnt find my root. (Probably Su hides fault). I tried root browser and that worked. So i deleted the Amazon Kindle app completely and my phone is 10x faster that it was! I think the amazon app was corrupted after failing to uninstall it via System app remover and TB...

Edit- Fixed root explorer.. LOL
[LG V20 Guides, News, & Discussion] emtownsend:
I get all the way down to ***********

Device should display a red triangle and say corrupt, then it will boot into TWRP.

Then my phone displays a corrupted screen that I can't read at all. Lots of lines and colors and the vibration will not turn off... Everything went very smoothly until after I ran step 3. The phone would not boot past the Verizon checkmark...

<<kinda freaking out>>
[LG V20 Guides, News, & Discussion] Lumince:
The static screen?? Alls you need to do is cover the sensor beside the second screen so it resets both screens and it should look fine again? Or have you not gone through the whole process?
[LG V20 Guides, News, & Discussion] emtownsend:
I was able to get through all these steps:

- Verizon(VS995) and ATT(H910):

4.1) Flash SuperSU.zip

4.2) Go back to Main-menu > Wipe > [Format Data] > Type ?Yes?

4.3) Go back to Wipe > Advanced > Check Dalvik,

On last try, after using SuperSU 2.79, it seems to be booting quietly. I have to go home, but I will touch bases when I get there. I hope it boots! Fingers crossed. It is at the Verizon screen with the check mark but it is not buzzing like a mad-man...........
[LG V20 Guides, News, & Discussion] Lumince:
Crazy vibrating only happens when you pull the battery and put it back in, or its charging while it reboots... Doesnt happen when i keep it off of the charger. I hope all goes well for you!
[LG V20 Guides, News, & Discussion] emtownsend:
Weird. Still no go. I let it set at the Verizon with checkmark screen for a half hour again and it never went further. Do I need to flash some sort of image from TWRP at this point? Now, when I boot with volume and down keys, I get the red triangle followed by an attempt to boot ending in a screen with multiple black lines with a screen that looks like bad TV reception. All sorts of colors and totally unreadable. Now what? Is there a way to start over?
[LG V20 Guides, News, & Discussion] twistedvip:
You really should read even a handful of posts in this thread, but the static screen youre referring to is normal. Simple fix is to turn off the screen and then cover the proximity sensor to turn the second screen off. It takes a second or two sometimes to get the screen to turn off, but once you get them both to turn off it will fix itself.
[LG V20 Guides, News, & Discussion] emtownsend:
You're right, I totally need to do more reading but there are sooo many pages. I've been trying to search without much luck.

I can get int TWRP still, which is good news. Question- how do I turn off the screen once in this jumbled color screen? Power doesn't seem to respond.

From TWRP can I run a recovery of some sort?
[LG V20 Guides, News, & Discussion] twistedvip:
That's fair, one of the busiest threads ive seen in awhile.

But as for turning off the screen, typically the first boot takes about 15 minutes or so to finish as its initializing all of the apps for the first time. Idk if youre on stock or another ROM, but if its deODEXed then it takes even longer to boot. But after that first boot, it is a lot shorter. What typically happens for mine is that when its booting, it will load the boot animation (which I can barely see) and goes a little darker. Then when I'm at the lock screen I can tell because it becomes a lot brighter. Thats when I press the power button. It should still work, maybe just try to reboot once more?

One of the only kernels that fixes the static boot is the werewolf. But that has touchscreen issues which I would not recommend risking as the static boot is much more tolerable imo.

You can flash Tilde88's NSS ROM or any other ROM you desire, I enjoy more of the stock feel so I use NSS. Hopefully that is a good start and helps you out
[LG V20 Guides, News, & Discussion] Lumince:
I may have explained it terribly when i said it the first time... But hopefully he can get past it :/
[LG V20 Guides, News, & Discussion] emtownsend:
OK, you were spot on... I had to wait longer for the ROM to boot even though it was in the weird screen state. I hit power and the screen turned off, then when I hit power again, I was up and running with a custom ROM that I flashed moments before. (Ressurection Remix ROM).

Now I have no cell service but I think that is because I need to complete the remaining steps, correct? Because I still get the red triangle at boot as well. Whew! What a stress reliever. Hopefully next post will be a total success story! Thanks again!

EDIT: OK.. I'm an idiot, I admit... I flashed a T-Mo ROM[h918]. Surprised it works. Well, almost. No cellular. I am flashing US996_deODEXd_Stock_NRD90M just to get myself re-oriented.

BTW, I never did load "boot2.img"... What is that? Does that fix the triangle?

When I attempted:

My result was "error: cannot load 'boot2.img'

well i have read the whole thread and is still not clear to me. will this work on the at&t version with the dec.security update

Are there plans to make this reversible? I have absolutely no interest in doing anything to my device that can't be reversed using a manufacturer tool or somesuch (ala Odin w/Samsung).
[LG V20 Guides, News, & Discussion] poixninja:
I think all but att and sprint are reversible.. And all can be if the kdz file is released
[LG V20 Guides, News, & Discussion] xaronax:
I can't find any reference to that, and the OP still says 100% irreversible. Where'd you see that? (I'm on Verizon.)
[LG V20 Guides, News, & Discussion] poixninja:
Verizon is able to return to stock using the kdz, have had to do it myself. Its mentioned a few times here and there is another thread with the vzw is file
[LG V20 Guides, News, & Discussion] twistedvip:
It's true on being able to revert back to stock using LG UP and the .kdz file. Theres posts saying that they have been able to revert back, so if you dont believe it then search through this thread of other threads around this forum.

But ATT and Sprint do not have a .kdz released yet and thus we cannot go back, but other variants are able to. Just verify your variant has a .kdz before doing anything.

So you haven't been through twrp yet. Do the HW keys method(VOL- and power until you see LG then release power ONLY and hold both keys again until you see factory reset. Say yes twice.)

[LG V20 Guides, News, & Discussion] me2151:
From power off do the HW key combo for factory reset. VOL- and power until you see LG then Release POWER ONLY and hold both again. then select yes twice and it will boot twrp

Anyone figure how to bypass SafetyNet?

I realised with the new SafetyNet there is no way to bypass with Magisk and PHH'S SuperSU

Cause of the verified boot

We need a rom with a modified kernel that dose not verifi boot

I found a way to remove the static boot but doing so messes up the radio again. The radio will not work

More testing needs to be done for that.

But if I get a no static boot and Radio working I will post the steps.

This has been covered numerous times including being posted in the OP. Search is your friend!

You need to run a different kernel.
[LG V20 Guides, News, & Discussion] midmadn:
Mine does that on first boot after flashing a rom. I give it about 15 minutes and if it won't power off the screen I do a battery pull / restart and it has always booted this second time. Still get the static screen but after a few minutes it will power screen off then cover / darken the front of the phone and it's good to go.
[LG V20 Guides, News, & Discussion] 3r0k:
For any att users having freezing issues at any point in this process after TWRP is flashed, to at least get a bootable smoothe rom, just restore the stock backup posted in the guides section. Make sure to also follow his instructions and flash the kernel from the notsostock ROM. I haven't tested flashing other Roms but this stock rooted with that kernel is buttery smooth.

So as I am reading most of this, There is no way to get rid of the "Phone is corrupt" boot screen? it really messes with me trying to get into recovery, Is there an easier way than the button presses, maybe an app or setting?
[LG V20 Guides, News, & Discussion] twistedvip:
That screen is through the bootloader. Anytime you have your bootloader unlocked for any phone, that will happen. People have sometimes done work arounds for other devices but they are almost always device specific when it comes to bootloader stuff and the risk of hard bricking your device increases significantly with bootloader modifications.

Honestly the screen isn't a big deal in my opinion, but to each their own :)

But yeah just keep trying to do the button presses, it sometimes takes me a couple of tries.
[LG V20 Guides, News, & Discussion] Ragnell:
I really dont know how to time it, i get so damn impatient, other wise i wouldnt care about that screen, maybe if someone did a quick youtube tutorial of it, it'd help me
[LG V20 Guides, News, & Discussion] twistedvip:
You just have to press and hold down both the volume down and power button at the same time while booting up. Immediately when you see that LG screen let go of the power button for not even a second and press it down again. Sometimes the red warning comes up before you can press the power button again, if that happens just take the battery out and try again. Usually the second time around it gives you more time (from my experience).

At that point you should see a white screen asking if you want to factory reset - press yes and then yes again. This does NOT factory reset, but instead brings you to TWRP.
[LG V20 Guides, News, & Discussion] Ragnell:
