Hi,
I purchased the phone in the UK from the network carrier Vodafone. I have done a fair bit of research on the rooting and unrooting process mainly via videos and reading tutorials on XDA.
I would like to root the phone and gain super user access and install some Xposed modules but would also like to be able to unroot and flash back to a stock Vodafone firmware encase I need to claim under warranty. I have been trolling the internet to get the correct KDZ file and found this site (ttp://devtester.ro/projects/lg-firmwares/country.php?country=United+Kingdom). I believe that the correct firmware may be on here but am a little confused on what the suffix and software version means to be honest.
The reason for my confusion is that I updated the firmware to 6.0 Marshmallow through the LG bridge but when I now check my phones software version it states v20b-234-15. I assume this is right but from memory the first software version when I got the phone was something like H81510B_00.
I cant remember exactly what it was before unfortunately but the KDZ files I have found state H81510C_00 (Suffix - AVDFVK) and H81510C_00 (AVDFLR) and this does seem to make sense but I'm thinking it was B instead of C but and not 100% on that.
Do you think these KDZ files would be the correct one to flash back to encase I run in to some problems rooting?
I am also assuming that this KDZ is Android Lollipop and not Marshmallow so is it OK to use this to revert back from Marshmallow?
Thanks and any help would be much appreciated.

The 10X version are all Lollipop, 20X is marshmallow.
When flashing a KDZ on your phone, what's important is what model your phone is. H815 in your case.
If you want to restore to stock in case something goes wrong, you can find everything here: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
In there is a link to this directory: http://storagecow.eu/index.php?dir=Xda/LG+G4/ where you find pretty much all KDZ files for G4 phones.
I'm not that experienced myself, but I rooted my phone just recently and I can share my experience with you.
I have a H815. It was a V10c-TWN-XX version (Taiwan). I updated to Marshmallow with LG Bridge also and the new software version was V20b-TWN-XX.
Marshmallow rooting is not possible on my phone because I can't unlock the bootloader on it. And Marshmallow rooting is only possible with an unlocked bootloader. Unlocking the bootloader is only possible on European phones (http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryTypeCode=ANRS). I asked autoprime (renown user and developer here) if I can unlock bootloader after flashing an European KDZ on it. He said no, having European software on it is not enough, it has to be a phone manufactured for the european market. Dont know why, guess because of different hardware.
So, not being able to root MM, I had to revert back to stock (downgrade) using one of the KDZs.
I chose the most recent one in the directory I linked (which is the Poland H81510E). In the "Go Back to Stock" thread I linked the OP says to use LG Flash Tool 2014, which unfortunately doesn't work with Marshmallow. But fret not, it works with LG UP! http://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803
When I tried flashing the KDZ with Flash Tool 2014, the process failed with an error at 5%. It worked flawlessly with LG UP. Here's more information regarding downgrading, but it really isnt hard. Just download + install LG UP. Launch it. Connect your phone. Choose KDZ file. Select option "upgrade". Hit start.
NOTE: after the firmware update was done, the phone rebooted automatically and for me it stuck at at the LG Logo (bootloop). But a simple hard factory reset did it, the phone booted and my new version was 10e-something. With Lollipop 5.1 of course.
After that, I rooted my phone using this pre-rooted image: http://forum.xda-developers.com/g4/development/h815-eu-l-p-t-sea-twn-t3176195
and this guide: http://forum.xda-developers.com/g4/...-tmo-vzw-intl-variants-soon-root-lg-t3164765/
I now have a "H81510e-EUR-XX" Lollipop 5.1 with root (SuperSU 2.49).
I don't really know about Vodafone and if carrier specific firmware is necessary in this case. If not, you could use any 815 firmware.
From the site you have linked with the KDZ files..... it seems they are all the same.
If you check the table for H815 KDZs from Vodafone, there are some 10C and 10D versions. Now I compared the fileKey parameter in the URL to the 10C files and the 10D files and also the bytes of the files.
All the 10C version are identical to each other, same for 10D.
Check out this screenshot I made for you: http://i.imgur.com/Ie0w4us.png
Bytes are also identical, so it's pretty safe to say those are the same files.
Dont know why they are listed several times there. The suffix doesnt matter.
I'd grab a 10D if I were you. But I think the Poland 10E should work, too. Better confirm it with somebody else though.
If you flash your system to 10e, you can use the pre-rooted image I used. Otherwise you will have to inject root yourself: http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586. In this method you create an image of your system and inject root into the image, which you then flash back on your phone.
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.
:crying:
My issues is quite complicated. Please be patient and read on.
Less than a week ago, I bought an LG G3 D855. It wasn't brand new and definitely out of warranty.
It was on the 4.4.2 Os version but I couldn't update it because I couldn't locate the UPDATE CENTER and after some research online, I found out it was because it was rooted. I couldn't find a Supersu application anywhere on the phone anyways but Root checker confirmed that it was rooted.
I downloaded the stock kitkat firmware in a .tot format and I tried flashing using LG Flash Tool for TOT but it failed because "Device version is different"
I checked the Imei online and it stated that the device is a Sprint LS990 but the details embedded in the phone all say it is D855
I checked online and found a couple of posts about this error and one user said he was able to fix it by flashing the actual Sprint .tot with the lg flash tool. I tried that but it didn't work. It still said "Device version is different. Check BIN or dll"
I checked online and found results pointing to a generic .dll file for G3s and I downloaded it but when I used it on the Flash tool, it resulted to an error "CrossDL blah blah"
So I found a Marshmallow kdz file. LGUP won't see my device model so I was able to flash it after editting the software in my build.prop to D85510n.
***I have always changed the port to COM41 in all the steps I used
The LG UP detected my model and it flashed to 100% but got stuck on a bootloop by loading the lg screen, freezing and restarting by it self. It never gets to the homescreen.
I downloaded lollipop kdz reflashed using LGUP in a form of downgrade and it got to 100% and got stuck at the lg screen while trying to reboot.
I redownloaded the stock kitkat rom and used the Lg flash tool but it failed. It said 'PID null IMEI Null"
I used LGUP to reflashed. It came to my understanding that the LGUP can flash both kdz and tot. So it flashed to 100% but got stuck at the lg screen and I have tried all I can but it is stuck. It can go into download tho. I don't know what to do about the IMEI. I don't know if the last flash retrieved it. I don't kniw what to do.
It no longer shows as LGE AndroidNet USB Serial
Please can anyone help me?
I just need my phone to work again. I was stubborn and now I regret it. I should have just stuck to kitkat. I'm so desperate to get my phone working that I wouldn't mind Android Froyo Os if it was ever possible.
PLEASE HELP!!!
I think you have to repair the IMEI...
maybe this can help

I think that he forgot to hard reset after flashing the kdz.
i completly know what you should do:
1: force your phone into qualcomm 9008 mod.
2: use board diag unbrick instruction and it will boot on download mod. for unbrick you will need best kitkat tot for your G3 model.
3: flash best lollipop or kitkat tot to make your phone alive
and then flash it with any kdz you want(it should be for your G3 model)
my telegram ID : @Erfan_rv
pls help me
Apparently, it seems my bricked phone keeps disconnecting during flashing process. I dont think it the fault of the cable because I have used different ones and they all seem to work fine with other phones. I have tried a different computer and still the same results. it connects as qualcom 9008 but once I try to start flashing, it disconnects and interrupts the flashing process. my phone just shows a grey screen now when I power it up with the battery in. also, I was trying to upgrade from linear os to the latest linear os. I cant fine the tot out there so im using zv6 currently. could this also be the problem? thanks in advance
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.
Hello everyone! Please, I need your help!
I have a problem with my LG K410G (Telcel, Mexico) beacuse I cant flash it with LG UP! My phone isnt bricked, but I think I have a persisten malware and also I have a lot of software problems, like unable to update Google Chrome (It gets forever updating and never does it, and the app gets corrupted after that). I had done factory reset, lg bridge recovery and update with lg up but it doesnt help.
I want to CLEAN IT completly, all partitions, with original firmware but LG UP says it "Does NOT support Refurbish Process", I have tried 2 Firmwares from this webpage: lg-firmwares.com (K410g10a_10_0220.kdz and K410g10a_05_0923.kdz) and neither works with refurbish option. Just update option in LG UP. I'm using UPPERCUT.
Thank you so much for your help!!
