Hi, All. Ive followed XDA for a long time and love it. I love my verizon G-Pad but ever since the Lollipop update it has just been so slow and almost unsuable. Well ive got good news. Today i found a way to downgrade back to LG Official Kitkat 4.4.2.
Tool Used: LG Flash Tool 2014 - you can download from this thread
http://forum.xda-developers.com/showthread.php?t=2785089
I could only get this to work from LG's Download Mode (with tablet turned off, hold the Vol Up Key and plug in USB cord)
If you are running version 23A Lollipop you must downgrade to 22A first. Attempting to downgrade straight to 11A (Kitkat) will fail at 57% restore.
After downgrading to 22A, allow the device to fully boot then shutdown and return to download mode
Now push 11A firmware, everything should now go smoothly (at least it did for me)

Many Many thanks to the Devs of the LG Flash Tool for such a wonderful utility on LG Devices
tutorial?
How do I downgrade to 22a?
In the Firmware download link I've provided is the 22a and 11a firmwares. Follow the LG Flash Tool link for usage.

Hey man gotta question, my pad was on lollipop and only rooted with no real tweaks and I rebooted one day and it sticks at the Verizon logo. I can get to stock recovery where any selection goes to fastboot where any selection goes to a blank screen where I have to kill it. The couple others I've seen with this problem had success with the support tool / update recovery deal but mine says everything is up to date. I tried flashtool with a kdz and I get all the way to it supposed to send it but the tab download stays at 0% and nothing happens....I would rather have kk anyway would it be worth trying this , **** can't hurt the damn thing no worse lol tired of it sitting in my dresser where its been for months ...I really wonder wtf happened to it
EDIT...... OK I feel like a real dumbass lmao... Apparently the pc I was using had an Antivirus on it and apparently the flash tool doesn't play well with an Antivirus
OK has anyone found a twrp that will flash correctly on the vk700? The twrp floating around for gpad 10.1 only works on the v700 cuz its been bumped To work on the locked bootloader....

Well this downgrade is for vk700 not v700 which is a big difference, I found that out by trying to get twrp to work on my vk700 when it's only for v700 which if you have the v700 your better off

hey, im using D855 LG G3, i installed CloudyG3 (LG G4 ROM) and its really stable but i need back to stock now. But im worried about the kdz and TOT method. i used kdz method 2-3 times, didnt use TOT method. anyway i have a question ; Can i use the LG PC Suite for back to stock rom? becouse if i download the kdz from internet, its modified there are too many apps on rom (china apps) i dont want them i cant trust (it wont be rooted if its back to stock). i used lg pc suite too many times, or can u guys give me the original D855 v20i kdz file link (v20i-SEA-XX) im not sure about v20i-SEA-XX or XX-SEA-v20i but im sure, its v20i and SEA..

I don't think you can, but, if you download the kdz from a trusted place, you are actually back to stock without "china apps".
You can download the kdz here: http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/
but be sure to flash the good one

Hey, friends. How are you all? I have lg g3 d855 (16GB and 2 GB version) in Pakistan. Software version is v20h-Global-SI.
LG PC Suit says that I have new update but due to low internet speed it takes forever to download new version of software which is D85520L.
I installed an app "Lg Phone From" from play store. It also shows new firmware available to download for my LG G3 is "D85520L-00.KDZ". I have downloaded this file.
I want to know a few questions.
Is the file Downloaded from "Lg Phone From" correct? I don't want to brick my phone.
Will I still be able to get OTA or update with LG PC suit after flashing KDZ?
Sorry for these stupid questions. This is my first LG smartphone. Due to alot of variants I am confused. Please guide me in this regard. I will try to explore forum for more help. But your answers can save my time. Thanks
Yes it is the correct file for you and you will still get ota updates.Basically you can flash any kdz from different regions that are for d855.
E.g i was using v20u which was for U.K but my phone was from australia(optus network) and was working fine.Now i'm using a custom rom based on stock.
Aslam O Alaikum Umari bhai.
Thanks for help.. JazakAllah.
I have the 22a kdz, but the software I've downloaded to flash it onto the vk815 isn't working. Would someone please point me to valid files for downloading? I tried the apps to SD hack, and that makes my software modified. That didn't seem to work, and maybe why the 23a update still gives me unexpected SD ejection. I want a clean pure install. I'm not concerned about root.
Hi.
First, are you using the original USB cable with a USB 2.0 port that comes directly off your Windows PC's motherboard - not a USB 3.x port and not through a USB hub?
Installed the latest VK815 drivers from LG's website? Reboot the PC after while the device is disconnected from it.
Once you put the device in Download mode, check in Windows' Device Manager in the Port section to see if the device is listed "LGE...". Until it is, any attempts to flash a KDZ or TOT will be futile. It can take up to 5-10 minutes to load the driver you installed, and USB works by loading the driver separately for each different USB port you plug the same device into.
If you Google:
Code:
XDA LG Flash Tool 2014
you'll find it. If that's exactly what you're using and it's not working, could you please be more specific about how it's not working? 99% of the time (maybe only 95%) ignore any error dialog that pops up from it, move the error dialogs out of your way if necessary but don't click on any buttons in them, and within 5-10 minutes you'll find your device is flashed. This is true in general for all LG devices.
You should also be able to use the official Verizon-LG software on your tablet, if absolutely needed. When you first plug it into your Windows PC it comes up as "Installer" before it switches to MTP or another mode. Install that from Windows and the official tool will download and install the latest KDZ that's released (23A? - I have the VK810 so not sure what latest VK815 releases are). The difference between the official tool and LG Flash Tool 2014 is the official tool downloads the newest KDZ every time you choose to upgrade/update with it, and can't make use a pre-downloaded KDZ, and then deletes the KDZ when it's done flashing although if you're fast enough you can copy it elsewhere while it's flashing so you have it handy. It's the easiest way to get the latest KDZ for any LG device on Verizon these days, when it's not available any other way yet.
When you flash with LG Flash Tool 2014, use the CSE option which will wipe everything including user apps, user data and internal storage.
Lastly, if you return to stock and the problem persists and it's still under warranty, LG has excellent warranty service.
Thanks! It all seems like I was doing everything right. I'll give it another go as you've directed, to be sure. It was my understanding that perhaps when it updated to Marshmallow, the flash function was deactivated? Maybe that was just for installing images and not flashing firmware.
Yep, fails to connect. Trying to install the LG UP CY dll for vk815, getting an Error 2356. Bummer.
Crap, just lost everything I just typed.
You verified the tablet shows up in Device Manager while it's in Download mode?
You were trying both LG Flash Tool 2014 and LGUp or just LGUp? LGUp doesn't work with all devices (not the VS985 Verizon G3, and I don't think my VK810 Verizon G Pad 8.3).
On the VS985, when 35B Lollipop 5.1.1 came out, we could no longer flash older than the 35B KDZ. We could only downgrade from 100% stock on 35B and higher by using our 10B TOT along with the .DLL that's extracted from the 35B KDZ. I don't know if you can get your hands on a TOT for the VK815, they're rarer than KDZs and usually have to be leaked by someone on the inside, I think.
Also, sometimes a different Windows PC makes the difference.
Yep, turns up OK. It starts to connect in LG UP, but fails after a few seconds. The specific driver also fails to completely install.

I don't know if LGUp works with the VK815. It doesn't work with the VS985. Good you Google for and try the LG Flash Tool 2014 I had mentioned?
There's a driver packet for the vk815, but it wasn't compiled right, or something, and fails to install. I may have a shot if a clean version can be found. Flash tool 2014 is reported to not work after Marshmallow is installed. That is true.

If LG Flash Tool 2014 can't flash your older KDZ while you're on Marshmallow, then LGUp won't be able to, either, as far as I know. LGUp doesn't get around stock bootloader and laf (Download mode) limitations.
Is there a TOT for the VK815? That and using the newer .DLL that comes inside the latest stock KDZ is the only way to downgrade from Lollipop 5.1.1 and Marshmallow on the VS985.

I suspect the new dll pack is for LG UP, because Mm update 'closed out' the old flashers.
Shoot! I just realized you may be thinking I want to downgrade. Nope, only wanna clean install of Mm, as mine currently reads as 'modified'.
The other day, I was messing around and got into recovery where there is an option for debug mode! Gonna have to try that to see if anyone will see the tablet. Not sure, but it may be feasible to push the system image via ADB?
Update: debugging mode yielded no change. Guess I'll just have to wait until either Verizon or LG gets their thumb out their ass and develop a better driver file for the LG G Pad X 8.3.
im looking for the same thing, trying to get my vk815 back to stock, its currently rooted on lollipop. the only kdz files i could find are MM but flash tool wont flash them, if i could find an older lollipop kdz i think it would work.
I recently found/installed new drivers/programs, but haven't bothered with them. My tablet still has the mysterious sd ejection bug, despite the latest update.

so did you figure out how to flash a kdz file with the vk815 tablet? if so which flash tool and files were you using, if possible could you please share a link? I have both LGFlashTool2014 as well as LGUP, but the only kdz files I have are all marshmallow, and I could not find a dll file to use LGUP for the vk815.
I played stupid and sent my tablet back to LG to have them reflash official firmware. I haven't messed with it since.

hmm well, i sure hope I dont have to send it back to LG, the root method I used was posted by player911, he also posted a method to unroot, but the KDZ files are no longer on the internet.
Hi.
I purchased a second hand LG G3 quite a few months back, only to find out after trying to update that my version was the D858HK, which does not seem to have any official way to update past KitKat on the phone. After some digging around, I did find some methods, like flashing the KDz file. However, none of the KDz files I've found on the internet seem to match the model of my phone, which is D858HK10d, or v10d.
I was wondering if there is any other way to get rid of KitKat and move on to the newer versions.
It is rooted.
Thanks in advance, XDA Forums. You guy's do the Android God's work.

Did you try LG PC Suite?
Also here is the Marshmallow kdz file.(The first one)

LG PC Suite doesn't recognize the phone. And the kdz files there dont include the model of my phone, which is a D858HK10d.
Where are you getting the model #? The 10d part may refer to the ROM as 20x would be LP, and 30x would be MM.

10d is the Software Version of Android KitKat..
Your device is D858HK.
So you can proceed installing that kdz file.
