So I have a D855 16GB LG G3 running CloudyG3 2.5 and I've been trying to revert it back to stock android in order to update to Marshmallow through LGs PC Suite. I've tried following various guides to either flash a kdz or tot to android 6.0 directly. I've also tried to downgrade to a previous version of LGs stock android but they've all failed. When I tried to use LGUP from this link it discovered my phone and displayed what software it was running and such but the model section stated "unknown" which made it impossible to proceed.
I then tried the second option in that thread, flashing the kdz with the lg flash tool. That journey ended when the program stated that no device was plugged in, even though the phone was definitely plugged in and in download/firmware update mode.
The third option in the guide was to use a flashtool and flash a .TOT, but when I entered the device manager to change the com port of the LGEModem but that one didn't show up in device manager so that also failed.
I'm starting to see a connection here in that the problem lies in the connection between the phones and the pc somehow. I'm using the original usb cable if that matters. I have TWRP 2.8.6.0 installed if anyone knows how to install the stock marshmallow update using that. I found one guide but it said that it required TWRP 2.8.7+ and I'd rather not try to change it since I've had a ton of problems with different recoveries, namely being that the touchscreen doesn't work in most of them.

Try with above link also firt uninstall .dll and lg up fresh install again.....i faced the same problem ....but after updated the driver my problem was gone...also check you install .dll file....check the size of your file with the new one.....
I got my lg g4 yesterday and tried to root it using the little effort root and it didn't work. When it rebooted I the screen that says booting failed etc etc with the LG logo on it and it cut off. So I tried to kdz it back and I guess I chose the wrong KDZ and it just completely blacked out. Luckily they gave me another 1 (told them it wouldn't cut on after going dead) so I want to try rooting it again but I want to know which software version am I? In my settings it says vs98611A but under my battery it says vs986B. Which 1 is my kdz? And is there any other way to root this phone?

Worked for me on 13B.
Suggest you update to 13B using LGUP PC tool and 13B KDZ, then try rooting again with link posted.
How do I know that I'm not already on 13 b? This is all new to me
Settings - About phone - Software info - Software version.
Ok I see. I think what happened last time was I was on 13b and flashed a 11a kdz and that bricked my 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.
I have been trying to root my LG G3 D852 on 6.0 mm, i have found that there is nothing out for that yet. I know know that have to downgrade and I have tried but since I'm on virgin mobile so the downgrade file I tried to use bricked my phone so i had to send it back to LG to get it fixed. Is there any other way to downgrade or root without bricking my phone again?
Thanks
Same problem...

Hmmm. I had the same problem as you did with my G3. Same model and everything. Tried to downgrade it using my computer. Can't remember what tool, but it said it completed successfully. When it went to reboot, it would stay on the LG logo for 15-30 seconds, before going to the broken android screen. After a few minutes, it would reboot. Could enter into the recovery menu from the broken android screen, but when I tried to bump the files or flash a rom, there was nowhere on the phone to store it. I think it removed the partitions during the flash, hence why it couldn't store the files. It's not that I didn't have permission, but it showed in the console that there was no directory to mount. Couldn't even charge the phone in the state it was in. Guess it relied on the OS to control the charging. I'll probably try to simulate the phone, with the stock OS, and see if I can find any exploits that could allow for a "safer" rooting method. Tell me if you find anything yourself!
Hello, I made the mistake of trying to use a remote unlocking service on eBay to unlock my LS992, but the person performing the operation somehow managed to brick my phone. The device is stuck on download mode, and though he attempted to re-flash the firmware it was unsuccessful. I was on the line with him for several hours with no fix in sight. He claims that the phone was on software version ZVA, but I am unable to confirm that as the phone is bricked, however, when I connect to LGUP it reports the version as LS992V3. I'm not sure if it is correct.
So the bottom line is, I would like to try to reflash the phone for myself, but I am unable to find the .dll files for the Sprint variant anywhere to flash with LG UP. I'm also unsure of what version stock firmware I should flash, as he said that flashing the wrong firmware might hard brick. Any insight on what to do will be greatly appreciated, or at the very the correct .dll file to use when flashing.
Thank you for your time and consideration.
