That'd would the closest thing but unfortunately it didn't work with my PC. It seems the term "recovery" doesn't exist for fastboot
[LG V20 Guides, News, & Discussion] AlkaliV2:
Edit: Seeing the same thing as you now. Can't get to recovery from fastboot. I'll let you know if I get it sorted.
[LG V20 Guides, News, & Discussion] me2151:
BTW this is not a command.
[LG V20 Guides, News, & Discussion] AlkaliV2:
Yeah, that was bad advice on my part. I looked it up after trying it myself and seeing that it threw me into the fastboot help menu.

So what I'm going to do to make up for it is determine the commands to get to fastboot and recovery and list them here.

i finished the the rooting process stuck at bootloop after doing a factory reset its bootlooping into recovery..how do i fix
[LG V20 Guides, News, & Discussion] me2151:
You don't factory reset. you didn't didn't decrypt the device. Re read the instructions. You need to hit FORMAT DATA not Swipe to factory reset.

i was reactivating my lg v20 with a sprint online chat person because when i was trying to root ealrlieri had to do a delivery so i had to switch service to my l g3 so i can make my deliveries but when i finished i rooted the v20 but it didnt have service so i switch it back but sprint wanted me to do a reset and i wasnt thinking,,,now im stuck in a bootloop can someone please help me out
[LG V20 Guides, News, & Discussion] me2151:
At this point it doesnt even matter. lol You should have mentioned you were sprint. Its WAY easier now. Install the sprint rom from the main page. just follow the directions. you weren't going to be able to keep your stock rom anyway. Follow the guide starting from step 4. sprint directions.
[LG V20 Guides, News, & Discussion] flymalikcool:
i did the instructions just now..still going back to twrp
[LG V20 Guides, News, & Discussion] cityneversleepz:
If you're on Sprint and want to run the Sprint dirty santa rom with magisk and "no static" on boot you can follow these steps. Download Schwifty kernel and extract the boot.img out of schwifty kernel. Put the boot.img and the kernel on you sd card. Also get the UnSu.zip and put it on your sd card. Download whichever version of magisk you want (ex. 16.0 stable or 16.4 beta currently) and put it on your sd card as well. Make sure you have magisk manager installed and match stable or beta setting with the version on your sd card. Then , flash the kernel, UnSu.zip, schwifty boot.img and magisk in that order. Static will be gone and you'll be rooted with magisk including passing safetynet.

Thanks in advance!
[LG V20 Guides, News, & Discussion] cityneversleepz:
People have had success downgrading zv7 and below but then have had all kinds of issues ROM related after rooting. I don't know anything about this other than seeing a few posts here and in other threads.
[LG V20 Guides, News, & Discussion] b8engl:
Yes, a lot of people complain about it!

I tested and was able to flash the 12A version from VS996.

After the process, I can't go to recovery ( do not know how ), and can not go to system ( stuck on Verizon logo ).

I'm able to flash back the 12A and start the process again ... but can't go pass over that! If I try to go to recovery by key combination, will reboot after i chose to enter, it will go to a screen that says that the system is not secure.

Any ideas on this?

Hello, I have a US Cellular V20 (US996) and had Lineage OS 15.1 on it working fine but decided to go back to stock. Stupidly instead of just flashing stock through TWRP I flashed US99610f_00_1205 via LGUP. I did not format data, and had to use the upgrade option in LGUP. Now my V20 appears to be looping infinitely, I've tried factory resetting from recovery and other kdzs. I tried to format userdata from fastboot but it errored because the bootloader is locked. Did I do something wrong? Should I wait overnight?

EDIT: Bootlooped all night, found another DLL for LGUP_common.dll (3,007kb) and it allowed me to refurbish and my phone booted right away :D

[LG V20 Guides, News, & Discussion] runningnak3d:
Yes, you can flash US996 on a VS995. Backup your EFS first -- modemst1 and st2 in case you have radio issues.

As a matter of fact, except for the H918 and LS997, any V20 can flash any other models firmware.

The H918 can't due to the RSA key and ARB. The LS997 can't IF the firmware on the LS997 is newer than ZV7 which means ARB has been incremented. Otherwise even the LS997 can be flashed to any other model.

Just to be clear, any model to H918 or H918 firmware onto any other model and it is an instant brick that can't *currently* be fixed.

[LG V20 Guides, News, & Discussion] cnjax:
I would add that if you use carrier specific features such as Volte or wifi calling you'll probably lose those features unless you find a a work around
[LG V20 Guides, News, & Discussion] runningnak3d:
I guess I should type up a post on cross flashing, what you gain, what you lose.

It is possible to have a fully functional phone on any carrier if you flash the correct partitions. Again, the H918 is the exception since modem is RSA signed and you need a RIL that will work with the modem.

hi everyone, did everything to the letter followed, currently was on H91010l ( AT&T ), did step 1 and step 2 no issues, wouldn't boot after 30 minutes so went ahead to step 3,

all is fine and step 3 was a success, booted in twrp and flashed supersu.zip and wipe data, however it is still not booting, I can still go to recovery but it wont boot to the lock-screen so short story I can access the phone from adb and boot recovery but cant boot it cause it is stuck on the AT&T logo screen, any ideas on what to do?

thank you

How long did you wait? On the old 10l firmware it can take upwards of 20 minutes for the first boot after rooting...

-- Brian
[LG V20 Guides, News, & Discussion] friend.evil:
thank you for the quick reply, its been over 40 minutes, maybe I can flash another ROM like Weta. worth a shot right?

Edit: so I flashed Weta ROM and it booted, then it auto reboots on the start screen. Kernel issue?
[LG V20 Guides, News, & Discussion] runningnak3d:
You really need to upgrade your firmware, there were all kinds of problems with 10c, 10l and 10m.

Download:

* 10r firmware

* mk2000 BTTF kernel -- Get the one for the H910

* Magisk 16.4

From TWRP (do it in this order and you don't have to reboot):

* Flash 10r

* Flash mk2000 BTTF kernel

* Flash Magisk

* Wipe everything

* Reboot

After you have a working stock 10r rooted phone, then you can worry about upgrading to 10u firmware if you want (although SuperV20 and Alpha ROMs work fine on 10r firmware).

Once you are sure everything is OK, feel free to flash the H910 version of SuperV20 or Alpha, or LOS 15.1

Give up on WETA and NATF -- or if you don't, then you will keep having problems....

Followed every single direction and when I got to Step 7 of the OP, I just got a static screen and it rebooted normally after 3-4 minutes. How do I get into TWRP again?
[LG V20 Guides, News, & Discussion] cityneversleepz:
Take out your battery and after a second or two put it back in. Hold volume down then power button until you see the LG logo screen. Without releasing volume down, release your finger from the power button for almost one second and then hold it down again. You'll see a screen. Use the volume as a navigator to enter yes responses with your power button. Yes twice and you'll be in TWRP in a few seconds.
[LG V20 Guides, News, & Discussion] anon389389109:
!!

This booted to TWRP for me after step 3; But after doing this for step 7, it just factory resets my phone. I don't know what I'm doing wrong!

EDIT: nevermind. I tried again and I'm fully rooted. The only problem is it's extremely laggy.
[LG V20 Guides, News, & Discussion] soldier9599:
I thought my phone was bricked (all is well, see update below), here's what happened:

I have the sprint version. I was in TWRP and had just finished wiping dalvik, system, data, and cache, when the battery fell out of my phone. I had not yet flashed the stock rom or supersu. Now I can't get back into TWRP.

I tried starting the phone while holding the power and volume down button and then press the power button again once the LG screen shows up. That doesn't do anything. I also tried it with volume up for the hell of it. I tried running "adb reboot recovery" on infinite loop in my shell, and it's returning "insufficient permission for this device". I am only able to enter fastboot, so I've tried reflashing boot1.img and TWRP, but that isn't making any difference.

== UPDATE ==

I finally got into TWRP. Here are the steps that I tried over and over again and for some reason it didn't work until the fifth time or so. I was flashing the recovery each time because I read some post somewhere in this thread saying that the LG software will delete TWRP, so I was just being safe. For the same reason, I was flashing it manually instead of the script step3.sh which reboots at the end.

1. Boot into fastboot.

2. fastboot flash boot boot1.img

3. fastboot flash recovery twrp-3.0.2-1-us996.img

(sometimes I repeated 2 and 3 over and over like the script)

4. Unplug the phone and remove the battery.

5. Hold power and volume down buttons.

6. Wait until the LG screen appears, then release the power button and press it again.

Every time I tried this, I just saw the LG screen forever, until finally one time it worked and I got the recovery screen mentioned above and I hit yes two times and then got into TWRP.

What's the most recent vs995 kdz i can have installed before I run dirtysanta?

Last time I did this it took me a couple tries & a somewhat old version before I found a version that worked with DirtySanta, I think, although I might have been doing it wrong. I'm still stuck on baseband "MPSS.TH.2.0.1.c3-00011-M8996FAAAANAZM-1.68646.1 1 [Aug 19 2016 03:00:00]" and I think it's causing some problems for connectivity for me? SMS & calls don't always seem to go through at a reasonable time.

Hoping someone can report back that they have had recent success with a vs995 & relatively new KDZ. What KDZ?

Edit:

"If you're on stock rom with Google's security patch of January 2017 or later then you need to flash a firmware with December 2016 or earlier security patch. " is mentioned in https://xdaforums.com/v20/how-to/guide-root-twrp-lg-v20-using-dirtysanta-t3722278. That's 12a, I recall now that being what I installed. Man I wish this baseband could be updated.

Is that after you type in the applypatch command or the I'd command, of it is the applypatch command it is because your firmware needs to be downgraded to be able to root your phone.

I have a Verizon LG V20. I had DirtySanta set up perfectly but decided I wanted to go back to stock. Huge mistake. I flashed stock kdz using Uppercut and now I can't get past the Verizon logo. :(

I've been thinkering with this all night so here's what I've tried.

- Using patched dll in order to download partitions in LGUP

- Using patched dll to "refurbish" rather than "upgrade" in order to format device

- Factory reset (This will say "erasing" for one second then restart)

- Cache wipe (Same behavior as factory reset)

- Different firmware versions

- LG Flash tool 2014 - 2018 (None worked)

Here's what I still have access to

1) Download mode

2) Factory reset

3) Cache wipe

Any help is appreciated :) thanks!
