I've rooted 2 VZW V20's. My first was on 11A and it went exactly according to process. My second was 13A and while it was successful (dirty cow is NOT patched in this version), I did have hiccups on some of the steps. Ultimately, there are ways to work around snags if you run into them.

Search for posts by name as I documented my issue (which others ran into as well) and steps to fix.

Stock 13A is running smoother for me than 11A so I do recommend keeping that version and not downgrading. Can't speak to 12A though.

Nothing wrong? it never rebooted and never went back TRWP. I couldn't flash anything. Unless an hour wasn't long enough I don't see what I did wrong. (Not saying I didn't)

[LG V20 Guides, News, & Discussion] me2151:
It wasnt supposed to go back to twrp by it self. You would have manually had to boot into twrp using the HW Keys method. All the colors you were seeing is the static on boot. the fix is on the second post. only thing i see wrong is you possibly did the bootbackup.img flash AFTER doing supersu. Which Yes would have caused it not to boot.

No.

Couple of things for everyone on Sprint --

Flashing the DeODexed ROM will cause you to lose WiFi Calling and Smart Lock features unfortunately...

I'm hoping that someone figures out a way to get the actual LS997 ROM working without all the bugs because I would love to get those two things back!! But on the flip side, I would trade them for having root any day of the week, so I'm still happy! :)

Unless someone knows of a way to get either of them back on this ROM (the US996) by chance?

Install the lg driver from the lg site. Then you need to manually update the driver in device manager. Right click the phone in device manager, select update driver, select manually install driver, then pick from a list, followed by android device, then LGE Mobile ADB Interface.

And exactly who TF do you think you are? Wheres the proof you got this phone in the first place because for all we know you stole it then sold it... They spent days/weeks trying to figure out root off that phone. If it was for there benefits then why did you make him buy the phone in the first place for your own benefit?? When you could have simply just pulled files and earned credit yourself towards getting root. Also is it was for there own benefit I doubt they would have released the root method to public, created there own site and make you pay for the damn root...

Second SuperSU Flash...

Having trouble again... I was able to roll back to vs99512a KDz and move through the rooting process. I get all the way through step3 and the initial device setup. The problem I have is that I can't get back to the TWRP screen to flash SuperSU the second time (step 7 near the bottom of the procedure). The "adb reboot recovery" cmd gets me back to a static screen that I can't screen cycle away. I pull the battery and enter reboot mode with V-Down and the power release method and get to the wipe menu. I say yes to both and instead of loading TWRP, it rolls back to a Static-y Verizon reboot and I have to run the setup wizard again (yielding no root). I've done this three times now and the only thing that seems to stick is the static boot screen.

Should I run Step2 again at this point, or am I messing up somewhere? Thanks for all the help!

I had that problem as well and ended up wiping the system folder from Step 4, mistakenly read the verizon procedure instead ot the AT&T and ended up with a softbricked device. Good news was that TWRP is still working for me so i end up flashing a Custom rom as well with a built in Root. If you're able to use TWRP i suggest you just go ahead and do the same and just create a twrp backup of the stock rom 1st. After that is done you can try the custom roms on the thread depending on your model device.

To reiterate: To properly decrypt the device you need to boot into TWRP and go to WIPE->FORMAT DATA and you will be prompted to type "yes" to format and decrypt.

[LG V20 Guides, News, & Discussion] Artimis:
After you manually flash TWRP in fast boot then pull the battery and reboot to recovery using the hardware keys (like you did before where it asked you to confirm wiping data). It should boot you back into recovery.

I've noticed that if you let the boot cycle complete to where you are back on the static screen it will wipe your recovery and you'll need to do it again. Once in TWRP flashing superSU should allow recovery to stick (personally, I would advise flashing the restocked 1.2 kernel first since it is solid as a rock and will get rid of any static after boot).

My Verizon LG G3 is rapidly dying and I am going to have go purchase a new phone and I'm heavily leaning towards a Verizon LG V20. IS this still the best method to root and TWRP a Verizon LG V20 since they tend to put out patches which block root/TWRP. Sadly there are posts in other forums but I only trust XDA.
[LG V20 Guides, News, & Discussion] me2151:
This is the only method. For Verizon if your phone has the update that blocks this you can downgrade
[LG V20 Guides, News, & Discussion] ArmOfAtlas:
You guys are amazing! It was a long journey, to be sure, but absolutely worth it!

I had a patched vs995 that I rolled back to the 12a KDz using LGUP and Uppercut. After that, I got the root to work and flashed the restocked 1.2 kernel to get rid of the static boot (and promptly made a backup). Next, I used ES File Explorer and modified the hotspot apk to get that working fully. Then, with Titanium Backup Pro, I froze the two system update apps to stop the auto downloads and annoying prompts to install them. I'm giving the WETA rom a trial run now, but everything is working amazingly!

The only bug... every other reboot or so the vibrate runs continuously - even after it fully boots up. To make it stop, I have to open the settings menu and back out. Just a strange bug and it could be WETA related.

Everything seems to go smooth for me until I reboot after going into TWRP and flashing SU/erasing data. When I reboot, I get the ol' Verizon hang where it sits at the verizon logo for over 20 min.

I wait for 20 min, then reboot into the bootloader, flash the bootbackup.img to boot and reboot.

At that point I have the screen static. I have tried to just proceed, but you can't complete the process if you can't see the screen.

Here is where I am stumbling. So I go back into bootloader and

fastboot flash boot boot1.img
fastboot flash recovery twrp-3.0.2-1-us996.img
fastboot flash boot boot1.img
fastboot reboot

That seems to be the prescribed fix for screen static. At that point, do I need to go back into TWRP and re-flash SU? Every time I go into recovery and flash su/wipe it's the same thing. Looks like it's booting. Goes to the verizon logo. I wait ~20min and then have to flash boot bootbackup.img, then I have the screen static.

I am sure I am going in a circle but I am not sure what I need to do different.
[LG V20 Guides, News, & Discussion] daw41:
The static screen is normal but if you want to get rid of it the restock kernel by [MENTION=5774816]BackCheck[/MENTION] found here https://r.tapatalk.com/shareLink?ur...share_tid=3556263&share_fid=3793&share_type=t will fix the static screen just boot into twrp and flash the zip then reboot
[LG V20 Guides, News, & Discussion] basicjim:
Thanks! I know other people had static screen, but I don't understand how they can complete the process with the static screen.

Everything seems to go well until I get to Step 7.

I run adb reboot recovery and it reboots into a static screen. I don't know if it is TWRP or not. I have done it several times and, if left alone, the phone reboots. I can't turn the screen off and back on to correct the static. I can't put it into recovery via hardware buttons either.

How do you get past that?
[LG V20 Guides, News, & Discussion] daw41:
If recovery is a static screen then it's not TWRP
[LG V20 Guides, News, & Discussion] basicjim:
Crap. Okay. I got into TWRP to do the origional SU flash. So I am doing something IN TWRP that is screwing up recovery partition or something AFTER TWRP that is screwing up the recovery partition.

After you said it wasn't TWRP, I tried several times to fastboot flash recovery twrp-3.0.2-1-us996.img I dont' get any errors at all but when I adb reboot recovery, same deal. Any reason why that wouldn't take?

I am running out of ideas!

Bricked LS997

My phone was stuck on stage two for a while, then I had a power outage and my pc went off. So I booted everything back up and I could not continue step two, so by mistake I executed step three. The phone was stuck on a twrp boot loop. By reading one of the posts I realized I had the backup of the .img files, I believe it was the boot.img, a guy with a similar issue got a response saying we needed to flash that and something else to get it back to stock. So I did. Still bricked and in twrp.

Step 2 only pulls a backup or your original boot and aboot.img to your computer. It sounds like this step completed if you have those files on your PC.

To get out of the TWRP bootloop, you can try doing the following while in TWRP:

1) Go to Wipe -> Advanced Wipe and select "data", "cache", and "dalivik/art-cache"

2) Wipe

3) Reboot System

See what happens. The system should boot back up and you will need to go into your developer settings to re-enable USB debugging before continuing to execute any adb commands while booted back into system.

[LG V20 Guides, News, & Discussion] Artimis:
That message is normal for this process (it's going to say that every time you boot moving forward). You didn't wipe your system partition by accident did you?

You can always mount the /system partition in TWRP and looking around through the file explorer to see if there is data in /system to be sure. Mounting /system and rebooting may also potentially work and is worth a try.

It does sound like you flashed a bad boot partition or you wiped /system though. Since there is no KDZ or TOT for your model, your best bet may just be to flash a custom ROM/kernel from TWRP and go from there.

---------- Post added at 11:01 PM ---------- Previous post was at 10:56 PM ----------

If you flashed SuperSU before you flashed bootbackup.img then you lost systemless root. You need to boot back into TWRP and reflash SuperSU.

Hopefully, reboot recovery will boot you back into TWRP at this point. If not, you'll need to do a few more steps.
[LG V20 Guides, News, & Discussion] jukbee:
I'm using VS995.

Is there any disadvatages to use boot2.img instead of bootbackup.img in daily usage?

Flashing bootbackup.img at the end stage just gives me problems - stuck in vibrating Verizon's boot screen, static boot, currupts root, unable to boot into recovery.

boot2.img solves all that.
