Correct, stock recovery

Hypothetically if I had the official .kdz for the ls997 couldn't I use LGUP? And if so, how long, if ever would the .kdz for ls997 be released/available?

He at least knew before hand. The problem was I gave him false hope, I googled how to restore stock for ls997 and I found a sight claiming to have .kdz's for all variants. It wasn't till it came in the mail and went to click on said download link I found it was missing the .kdz for ls997.
[LG V20 Guides, News, & Discussion] me2151:
kdz for sprint probably will never be released unless we figure out how to make one ourselves. Sprint themselves dont even have it(we have a few devs that manage stores)
[LG V20 Guides, News, & Discussion] dms21114:
Thanks, much. I had no clue.

Kinda a odd question but, what if I tried to flash a .kdz for a different variant? I already tried the Verizon and LGUP wouldn't let me do it because it knew it wasn't for ls997, but what if I tried to alter the identity of the .kdz, so LGUP would think it's for the ls997 and let me flash it. From there I should be able to root using this method and then flash a ls997 rom?

He took it to mobile comm and they said they might be able to flash each part manually? Not sure with what? Or how, but we'll see if they even can here in a few hours.

P.S. thanks for your time and effort, it's appreciated.
[LG V20 Guides, News, & Discussion] me2151:
You cant alter the KDZ. Not sure how they would do it either.
[LG V20 Guides, News, & Discussion] dms21114:
There's no way to extract it or anything? If they get it fixed I will update this post and see what they did. Maybe way outside the box, but what about changing the Id of the phone itself?
[LG V20 Guides, News, & Discussion] me2151:
You can extract it but it does you no good. and no way to change the id.

I bought a network-locked device today, (which means I'm restricted to using the device on Sprint and Sprint MVNO Networks such as Ting, FreedomPop & RingPlus) I'm on Sprint. This v20 is currently zv3. Will this procedure still work if I follow it correctly?
[LG V20 Guides, News, & Discussion] Artimis:
I fought with this issue last night as well. I'm guessing when you try to boot into recovery, you get a static screen and after 2 minutes or so you are booted back into the system normally (although you have static on the boot animation)?

If this is the case, here is what you can do to fix it:

1) Download the Re-stocked 1.2 kernel and put it on your sdcard

2) Reboot into the bootloader (adb reboot bootloader)

3) Flash TWRP (fastboot flash recovery twrp-3.0.2-1-us996.img)

4) After flashing is successful, unplug your phone and pull your battery!

5) Put the battery back in and reboot into recovery using the hardware keys:

- Hold Vol- and Power until the LG logo appears

- Release Power for a second and then press it again

- It will ask you if you want to do a factory data reset -- Select "Yes". TWRP will intercept this and boot you into it.

If your timing is off with the hardware keys and you are booted back into the system then you will need to start from step 2 again because it will wipe TWRP.

6) Once in TWRP, flash the Restocked 1.2 kernel

7) Flash SuperSu

8) Clear cache and dalvik and reboot.

Your phone will reboot itself twice and on the second reboot, you should be booted back into the system without static and rooted.

Hope this helps.

Hey dude thanks a lot for the guide, it was going great but stupid me I screwed something up, the phone is brand new and I wanted to use it over my S7 edge because it's cracked. If you can help me I'd appreciate it dude.

Preferably needing help from the guide creator himself or someone experienced such as an average exploit developer for android systems would be nice.

My problem: LGV20 vs995 Stuck in fastboot mode

Can someone help me? My VS995 is stuck in fast boot mode and my boot loader is locked (I erased something when I had TWRP up and running) , I screwed up during the wiping part of "me's" guide and wiped system and some other things. Whenever I issue a fast boot command it says "FAILED (remote: unknown command)" because the BL doesn't allow fast boot commands. Whenever I try to flash during download mode it installs and what not but then boots back into fast boot right after. Any help would be appreciated, have been trying to fix this non stop for the past two days, Thanks all.

What I've tried:

1. Flashing a .kdz file through download mode

2. Flashing through fastboot commands

3. Using Flash Tool 2014, LGUP (auto prime version and original), LG Mobile Support Tool, LG Bridge

What happens when I try those things: When I try upgrading recovery it just shows "fetching files from Internet this will take a few minutes depending on your Internet speed" Along the lines like that, I let it run for 40 minutes and being my Internet is 100+ mbps it should have been done if it was working. For autoprimes version of LGUP it installs everyrhing then just kicks me out back into fast boot after it finishes. Using fast boot commands as already said gives me output "FAILED (remote: unknown command)" whenever I try to flash or show oem information, the "fastboot devices" command still works though, not sure if others would too then. Please help :confused: :(

ok!thx!

so thank you for replying me !But i come across a problem now!Im vs995,Verizon.And

When you say:

It has come to my attention that some users have encountered abnormally long first boot time(over 20 minutes before first time setup)

To resolve this issue balabalabala...

I type 'adb reboot bootloader'into bootloader and do as you tell but CMD says 'cannot load 'bootbackup.img'

I dont know how to do next..

sry im just not good at speaking in english ...wish you could understand what im talking about...

:)
[LG V20 Guides, News, & Discussion] dijia1124:
sry I just want to use my phone and then I restore 'boot' and 'system' by twrp but when I rebooted it,it stopped at 'LG' logo..

Then I get into TWRP and wiped the 'system' ,and restore 'boot' and 'system' again ,but it still stopped at LG logo..
[LG V20 Guides, News, & Discussion] me2151:
Make sure you are in the ADB directory you used when you did dirtysanta the first time. there should be a bootbackup.img in that folder.

Jumped on the same deal, phone came today. ZV3, battery manufacture date January 20th so these aren't really old first run batches. Anyone wanting a V20 on sprint but not wanting to risk ordering from them and it coming with ZV6, this isn't half bad at all. Dirtycowed and confirmed my daily driver apps work. Now to see how difficult Sprint is about activating it on their network.

Would rather the G6, but my existing phone is long in the tooth and I don't want to wait around for root.

External SD card necessary?

So, I've been reading and searching, and I can't find an answer to this. I'm on Sprint, so LS997, and I don't have access to an SD card right at the moment, and I won't for about a week. I'd like to get my V20 rooted and up and running ASAP. Is there a way to do this without an external SD card?

Unless I'm forgetting something, wiping the phone will also wipe the ROM on the internal memory, leaving me with nothing to flash back onto the phone. I'm thinking I could maybe push the ROM and SuperSU back over onto the phone, but I'm unsure if that will work properly.
[LG V20 Guides, News, & Discussion] moejoe88:
What's up hicks? Haven't seen you around in a while. You gonna work on a rom for the v20? Rage kicked a$$.
[LG V20 Guides, News, & Discussion] fiver5:
I don't see why an adb push in twrp after wiping wouldn't work, but I haven't personally tested it.
[LG V20 Guides, News, & Discussion] je2854:
It STILL does not have ARB enabled so it is safe to downgrade AND you should not have to wipe or lose your data in the process.

I have rollbacked a couple of times and didn't even wipe cache.
[LG V20 Guides, News, & Discussion] spc_hicks09:
How's it going moejoe! Yeah I kinda dropped off the face of the earth for a little while lol. No I'm not working on anything for the V20. I was just snooping around here to see if root is achieved for the LS997 with the most updated security patch. I'm glad you liked Rage though, I might work on something soon again but right now I have the T-Mobile Galaxy S6.

[LG V20 Guides, News, & Discussion] Honestly Annoying:
Hey guys, just wanted to throw you some news about something new before you lose all hope for your updated device.

We are currently in the process of putting together a universal flash/image pull tool for ALL LG DEVICES. Yep you read that correctly, it has been tested on the LG G5 and the LG G6, and should work on all LG devices that have LAF/Download mode. This tool will allow you to flash any image to any partition, and will also let you pull images from the device (recovery, boot, system, etc). IT DOES NOT ROOT YOUR DEVICE OR UNLOCK THE BOOTLOADER, IT IS BASICALLY AN OPEN LGUP TOOL!!!

Please please PLEASE do not ask for an ETA, if you are interested in updates you can check out this thread here. Do not clutter that thread as it is for the G6 and not the V20, when the tool is finished we will make a thread for the V20 in the appropriate forum.

Peace out :good:
[LG V20 Guides, News, & Discussion] me2151:
Oh hes working on it again? the good news is that We v20 users can actually use it to root. not just for stock. The method it self works on the v20. Fluffy and I discussed it at one point but he had to put it on the back burner.
[LG V20 Guides, News, & Discussion] Honestly Annoying:
Yeah there's actually a few people working on it now, it's flowing really smoothly so far. Yeah for you guys it's a win-win situation because not only will you have a way to return to stock for ALL V20 variants without a KDZ, but you can most likely flash the insecure aboot (i say most likely because as of now the tool only flashes to sdeX, while aboot is located at sda1) EDIT: aboot is located at sde6 for the V20 so it shouldn't be a problem flashing aboot!

Just got my warranty replacement vs995. I previously rooted my last device using this method, however this time around following step 6

fastboot flash boot bootbackup.img
fastboot reboot

trashes my twrp recovery. If I flash that img file it makes it so I can no longer boot into twrp. I tried it 3 times with the same result and finally said screw it and when I got to step 6 instead of flashing that img file again this time from twrp I did the format data/wipe and flashed a custom kernel, rom and supersu again and everything appears to be working perfectly so far, but I'm wondering if I'm going to have any issues like poor battery, app force closes, etc.

Thoughts?
[LG V20 Guides, News, & Discussion] Artimis:
That step basically flashes the stock kernel over the debug kernel. If you are flashing a custom kernel instead then you are fine. You don't have anything to worry about.

Edit: just a guess but your first phone came with 11A and this warranty replacement came with 13A, right?

PLEASE HELP. (Willing to pay)

I'm Verizon VS 995 - and made it thru flashing SR5-SuperSU-v2.78-SR5-20161130091551.zip. After wiping and advanced wiping, I attempted the workaround "fastboot flash boot bootbackup.img - and - fastboot reboot" commands and after a few minutes the screen turned into fine mesh of colors (while still vibrating of course.) after 30 minutes there seemed to be no change (still fine mesh of colors) and I pulled the battery. I was able to reboot into fastboot mode by holding the Vol- down but adb reboot recovery (or any other command) gave me a "error: device '(null)' not found"

I've pulled the battery and awaiting direction from one of you find folks to figure how to proceed.

(incidentally - the SU file said it was corrupt on the fastboot phone screen but did say it finished. I don't know what to make of that.

This sounds very promising!!! I have some videos that I want to recover / perma undelete on a 10M. I would definately pay to get those videos recovered from my LG V20 H91010M with stupid April 1 security patch. :(

On another note, I'll take the chance to ask this now. Is there a way of making a mirror image of the internal storage? I was hoping to take a snap shot in time of the internal storage that could be used for recovery, for when the 10M could be recovered. Yes, I would really like to recover those videos as I will never get to take them again. :(

Also, any 3rd party recovery services from professional companies that anyone know about? i.e. disaster recovery

Thanks in advanced.
