sorry for this double post, admin can you please delete this, not sure i know how.

Did you get this sorted out? I'm having the same issue. the install starts then stalls after the progress bar barely moves....

I didnt face that problem, I've just installed in on my PC
Check your PC

Hi, I'm back, now I know why it stuck at 10% (in my opinion)
1. Try to use it in Win 7
2. Run compability at Win 7 mode (if you use Win 8 or above)
3. Check your internet connection

Hi guys. i have a news: dont have to use LG mobile support tools anymore. Search Google for: LG Flash Tool 2014

LG flashing Tool problem

I rooted my G3 using iRoot while having Lollipop 5.0 installed. I have just received my update from LG for Marshmallow. When I tried to do the update it told me that my phone was rooted so I can't get it. I un-rooted my phone, and tried to put everything back to the way it was, but no go. They still said my phone is rooted. The problem is that I can't do a hard factory reset. I get a message "secure booting error ...".
So after reading up on it a bit, I realized I needed to flash a stock ROM through my computer. I downloaded all that I needed, and installed LG Flashing Tool 1.8.1.1023 on my Windows 10 computer, following all the directions exactly (including replacing MegaLock.dll). The program installed, but when I wanted to run it, it told me that it couldn't find MegaLock.dll, and then asked for an ID and Password. I uninstalled it and reinstalled it many times using slightly different versions, but I had the exact same problem each time. Then I decided to try and install it on a Windows 7 machine, and it worked. So it seems that something is keeping it from working on the Windows 10 computer. Can anyone help me with this, or maybe there is another way? Maybe the dll file has to be placed somewhere else? Maybe a different MegaLock.dllis needed that is compatible with Win10? Maybe a different program? I have no idea. Any and all help would be appreciated.
Thank you.

My computer recognizes the phone, that's not the problem. It's purely the program, I can't run it. It doesn't open.

I had problems with LG Flashing Tool the first time I tried to flash stock after upgrading my system OS to Windows 10. I finally got it to work by changing the compatibility mode for application file to Windows 8. I successfully flashed back to D85510L_00.KDZ after making the change I just mentioned.

Thanks, but I tried that already. Didn't work. In the end I transferred everything to my wife's Windows 7 computer and and did the flashing there. Everything ran as smooth as can be.

Can't install Recovery or Downgrade from Stock MM 6.0

Hi,
I have a temprooted LG G3 (D855) with Official Marshmallow Stock ROM. I have tried to bump it using this thread, but the moment I have rebooted my device to recovery, I had no recovery at all and it has factory reset my device (don't worry, I had a backup). So I've decided to downgrade it to Lollipop or even to KitKat. I've tried to use LG Flashtool 2014. It had thrown an error on both versions (connection failed). I've read about it and found LGUP and even LGUP thrown an error. I've tried to do it agian from LG Flashtool (the old one) and it thrown this error: "CrossDL [] to [d855].SWversion()" and I've searched for this problem, and found a tutorial to remove this error (using Hex Workshop to delete the model) but Hex Workshop had stopped working when I've tried to save it. And I have a good computer (Intel Core i7 Skylake, 8GB RAM). Even before all that stuff, I had a temproot, which means every time I reboot the phone, the root just vanishing. And I've used KingRoot (which is a good root app) to root it.
Please help me. I want to install CM13 very soon.

Download a twrp bumped recovery img from the twrp site(https://dl.twrp.me/d855/), and Rashr or flashify app. Then use kingroot for your temporary root, then use Rashr or the flashify app to install recovery img, reboot into recovery, and then flash cm13 or whatever you want.
*I'm not sure about obtaining permanent root for MM on your SW version or your model(I have a vs985), but since you are flashing cm13 and not staying on stock you shouldn't have to worry about any of that mess.

You can repeat the whole process on a Windows 7 (32-bit) pc. I had the same problem while i was trying to restore my lg g3 to stock kitkat using flash tool (tot method) on my Windows 10 (64-bit) laptop. I am still unable to restore to stock on my laptop but this process works smooth on my brother's computer with Windows 7 (32-bit).
I am pretty sure changing to a Windows 7 32-bit pc will solve your problem.

That's exactly what I did. And it just removed the recovery. I've also tried to do it through adb and it also failed. I've noticed that there is some missing information in my build.prop file, and I've tried to fill it, but it had no effect.

Will it work in Virtual Machine? I have only 64-bit Windows 7 laptops... But I'll look for one. I'll try it.

OK, so I've tried it and it still won't work. I was using Windows 7 Ultimate 32-bit now.

I've solved the problem with a little help from CODEFIRE team: I've flashed the tot with the G3-CODEFIRE dll which worked perfectly.
I can't post link because I'm still a new member.
Anyone knows how to close a thread or add the [SOLVED] tag? I'm quiet new here...
Sorry about my bad english.

cant unroot G3 lgflash tool, pc suite.. twrp not working

Hello everyone i am in desperate need of help to fixing my g3... Out of nowhere it just stopped working and got stuck on the lg life is good screen.
I was able to access TWRP but i wasnt able do perform a factory data reset of any sort becasue it said that theres an error in mounting the internal storage, data and i believe cache. I then tried to community based unrooting process which uses a program from 2014 called the lgflash tool (youtube) and after getting about halfway through all the steps it just gives me an error saying that the software couldnt be matched or something like that. What else can i try? i am not in the market for a new phone right now and it just sucks that nothing is working. ive tried it on windows 10 and 8.
ANY HELP IS APPRECIATED!

You can try to use LG PC Suite IV available on LG's website. It will install the latest firmware on your phone

LG G3 Marshmallow to KK won't work

Hi, I just bought 2 LG G3 off of Ebay for my kids, I was going to put Resurrection Remix on them, I have it on an old Droid Turbo and have liked it.
Anyways I have followed every guide I can find and all seem to come back to use LGUP to go from Android 6.0 back to 4.4 to Root and install TWRP.
So, here is the last group of things I have tried.
Downloaded and installed in this order:
LGMobileDriver_WHQL_Ver_4.4.2.exe
LGUP_8974_DLL_Ver_0_5.MSI
LGUP_Install_Ver_1_14_3.msi
This is all installed in a Windows 7 Clean install in VirtualBox on my Windows 10 machine. I have tried a number of times of different versions of drivers and such on my Win10 box and just assume I've toasted it with all the install/uninstall.
So I have a Snapshot of my Win7 I keep reverted back to for testing different versions etc.
At this point LGUP will find my phone and show it on COM4 version D85030p and after 14 seconds it gets up to a Progress of 6% and then gives an error with the following in it
Code:
Error: [22:50:30] EXCE
Packet Error No :
0x8000010a
This is the file I am trying to write: LGD850AT-01-V10d-310-410-JUN-19-2014+0.tot
I've also tried to use LGFlashTool_1.8.6.527 with issues as well. I'm stuck, everything looks like I am doing it right from the different sources I have read.
Any help would be so appreciated.

Try downgrading to an early version of lollipop and root. There is an app that downgrades the bootloader to kk. I can share with you if you need.

Hi, thanks for the link, but that didn't work. I've tried a couple versions of Kingroot and it can't find a root strategy it says.
Do you have a link for Lollipop ? I have only found KK so far.
Any any other ideas I'm open to try, I haven't had any luck with these 2 D85030p's...

I don't know maybe these would work? https://firmware-up.com/lg-g3

So far no. I've tried 1 physical computer running windows 10, and a windows 7 vm running on the windows 10 box.
I have a couple other windows 10 boxes for my kids, I'll try one of them.

What option are you using in lgup?

Has anyone found a solution to this? I'm experiencing the same issue, using Windows10 (via Oracle VM virtualbox).

Using an actual install of Windows 10 solved this for me. Using a Windows 10 virtual machine wasn't able to emulate everything I guess.
