Doing it as we speak. Before I install any root type apps i'm doing a full backup (just in case) I also have the backup of jcadduono and a Rom.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] crazyc78:
Yes I believe so, that is why there is an option to go back to stock recovery and boot. I haven't personally tried it, but if someone wanted to go back to a stock unrooted state I am guessing that's what would be needed to be done as there is currently not a guaranteed way to go back to complete stock until we can flash TOT and kdz files through LGUP.

Ok that's your preference, just remember most mods need you to be in permissive mode for them to work correctly.

I'm having an issue flashing TWRP. it worked once but i didn't wipe data before restarting and now it refuses to flash my img file. It says my recovery is already modified. I have that option to have it ignore that (verification flag) but it tells me i shouldn't.

I also can't boot into any recovery. Adb reboot recovery doesn't do anything. Just starts normally. These two issues are most likely related. I was told that locking and unlocking my bootloader would help.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] netgar:
To clarify, just use option 1 and 3 for regular root.

Later I would like to try custom ROM's as well. So those options are ok?

Edit:

I used option 2 and manually flashed SU from TWRP. Everything is good.

Fastboot not working. Plz help. Tried many things with no luck

[MENTION=2961139]bezeek[/MENTION]

Hi, so I have been trying your method for a few days now with no luck. Was hoping you can guide me. So I am able to get adb working on my Win 10 and it boots my phone to the bootloader screen. Now the issue is that fastboot is not recognizing the phone. I have tried downloading the ”15sec adb/fastboot" from XDA, Android suite app to update drivers. But nothing has helped. I have tried both USB ports and different cables.

What am I missing here?

Would really appreciate your help.

Thanks
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] stanleyopar2000:
and this worked for you? no bootloop? you have TWRP now??

OMG YES IT WORKED YOU ARE AMAZING!!
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Linsolv:
I have TWRP, worked fine for me. It's because they're worried that your boot.img or recovery.img is bad; I wish there were an option to only ignore that one step, but since I knew why I had failed verification (I had TWRP and then lost root by restoring dead stock recovery.img, but not boot.img) I took the risk.

It is a little bracing, and of course since you're not in your situation, I can't say it's definitely fine. But that's what I did, no boot loop, have root.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] lennathi:
Unauthorized OR unrecognized?

If unrecognized, are you using Windows? If so go to your device manager and see if the phone is listed there, if not u plug the USB from both the phone and pc, then use a different USB port on your pc.

If that doesn't work disconnect the phone again and reboot your computer then connect to a different USB port (if possible).

Power off then power on the phone.

Check ADB.

Be sure the phone shows up on device manger (check under USB devices) when you connect it, without the yellow triangle next to it.

If you get the yellow triangle right click on the device, go to properties, and uninstall the device, reboot and use a different USB port.

Check ADB. Once you have the device showing up on ADB again reflash everything and see what happens.

Unauthorized? Go though each step of the rooting process and be sure you didn't skip any step unintentionally.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Zacharee1:
I hate to play the person who asks an already-answered question, but I need to be absolutely sure about a few things.

1. How much risk of hard bricking is there?

2. If I root, can I revert to full stock if I need a warranty replacement (i.e. is there some sort of Samsung KNOX for LG)?

2a. If I can revert, how might I do that?

3. The limited root shell in the tool: does that need TWRP and all the other rooting stuff or can I just run that without unlocking my bootloader?

Again, sorry for the questions, but I'd rather be as safe as possible (to the point where I will wait a year before rooting if necessary). The root reversal is probably most important to me.

Hi guys, I had a similar issue and was stuck for a week before I finally figured it out. Someone mentioned (dont remember who) here that once you follow the directions of "unbricking" the phone till the end, now instead of using TWRP to reboot, just remove the battery instead! Yes, this was the only thing that made my phone boot into OS, instead of just TWRP again and again.

Hope this helps guys

This method is dependent on Dirty Cow right ("recowvery")? Does that mean once the December security patch comes out and LG pushes it, we'll lose this root strategy?

I want to be able to plan: can I wait till the 23rd Dec or do I need to decide to root sooner?
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] KOLIOSIS:
No one here is Psychic,but,if you want to gain root access,now or in the future,hold off on updating.

Updates typically include patches for root exploits,& getting around such is becoming increasingly difficult.

The best security is one's own diligence.

Steer clear of pop-ups & freeware sites & you'll avoid better than 99℅ of any security issues.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Zacharee1:
Well I didn't expect anyone to have first hand knowledge on the update schedule of LG, but this is my first full-use LG phone, and my impression is they are better at updates than Samsung. I was hoping maybe there'd be a general sense of LG's updates. My general sense of Samsung is that we'd never see that security patch.

How should I avoid updating? With the new seamless updates, is there a way to disable automatic checks?

I don't care about security; that isn't my rooting dilemma. I care more about the warranty and the hassle of factory resetting without access to Titanium Backup.
[LG V20 ROMs, Kernels, Recoveries, & Other Developm] KOLIOSIS:
I'm pretty sure disabling auto updating in the Settings > About Phone section should do it.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] sanjsrik:
Hi,

I'm able to use step 2, the device reboots and then starts as normal but doesn't get past that, I have no dirtycow flashing and no recovery image flashing on the device. I'm not sure what is going wrong. The device seems to work fine. I have checked that OEM unlock is unlocked using the fastboot getvar all command which tells me that (bootloader) unlocked:yes is true.

I just can't flash the dirtycow exploit and I can't flash recovery.

**UPDATE**

I manually flashed the supersu after formatting.

I did the following as what's going on is the following:

I can run step 2 however, after reboot, the device is not found so it just reboots into regular phone mode, no recovery is flashed. When I run the command:

adb devices I get either the device name and "offline" or no devices found

I have to unplug and re-plug my device from my computer and run adb kill-server and then adb devices and everything is found again

I then run step 3 and the exploit is installed

I then unplug/re-plug my device and make sure the computer can see my device

I then reboot into TWRP recovery, and formatted data and flashed supersu

I had to re-setup my phone but I have root and everything is fine now.

I suspect that some may be having issues because the device on reboot after installing the exploit isn't being recognized and so recovery is not being installed. I'm no expert but this method worked for me so, if this helps, great. If I'm wrong in my methodology, my apologies.

Any help would be most appreciated.

[LG V20 ROMs, Kernels, Recoveries, & Other Developm] Zacharee1:
The files need to be in the same directory as the terminal. You'll see the path in the prompt. I really don't want to sound mean here, but, unless I'm misunderstanding you, maybe you're better off waiting for a one-click method. Knowing what directory to be in is pretty basic. Practicing in CMD/terminal with safer things than risking a hard brick might be better to start.
