I have a new LG G3 D855 whith 4.4.2 firmware and im trying to update to lollipop.
i use booth LG flash tool and LGMobile Support Tool and its allways stuck at 2%...
please help my
Why have you tried manually the upgrade from computer? Your device won't to recognize updates by itself?
However... be sure you have downloaded latest LG driver (I presume you're using Windows on your PC), here you can download the proper ROM file, while to flash them you only need LG Flash Tool 2014 (only one of the two cited softwares is needed).
At this point it's very simple to proceed:
> Plug the device into computer, probably your PC need to recognize phone drivers, if it happens be patient and wait for it to finish;
> Open LG Flash Tool;
> Select the downloaded KDZ file (the rom file to be flashed).
> Now if you want to keep upgrade without losing data, press the Normal flash button, if you want to do a clean and surely working installation, press the CSE Flash one.
Tell me if you solved or the flash have a failed result.
I found LG Flash Tool 2014 is not working any more for flash KDZ file go back to stock or downgrade/upgrade. LGUP is working better for go back to stock flash KDZ file. I bought G3 it came with Marshallow I looked everywhere but did not find any method working except use LGUP tool to downgrade or upgrade:
Download from this Vietnamese tread, it's working I flashed KDZ to downgraded from MM to Kitkat (D85010C firmware). It should work with other firmware LP 5.0 or MM 6.0.

For install the tool you just need to run the two Msi files, comport should be under port 41 under device manager I think. LG Mobile driver (LGMobileDriver_WHQL_Ver_4.2.0_001.exe ) should also install before LGUP tool.
Simple instruction include in readme text file with the LGUP zip file. For KDZ fine when first open LGUP you might not able to browse for it, close LGUP and copy/move KDZ file you want to flash to the same directory as LGUP tool (C:\Program Files (x86)\LG Electronics\LGUP\model\8974). Open LGUP again it should show KDZ file, for downgrade just choose refurbish it should work it take 2-3 minutes to flash it. Once the phone reset and start setup you can unplug the phone from the computer.
Note my computer is Windows 7, someone can try on Windows 10 and confirm it's working, cheers
Correction the Kitkat firmware I flashed was: D85110C_00.kdz for Kitkat on G3 D851
I am trying to flash the TOT and DLL files from https://forum.xda-developers.com/lg-g-pad-83/general/fix-v495-using-uk495-kdz-t3420711.
With LGUp, it sees my device and sees the com port, but it says unknown model and it cannot connect to it
With LGFlashTool, I get an error that says "Failed previous load()" when I try to perform the upload to the device. (The device is in download mode and I've moved the megalock file and selected the appropriate DLL and TOT file).
I have followed the instructions in several "how to flash TOT" threads and tried different versions of LGUp and LGFlashTool with the same results.
I am currently on 5.0.2 stock rooted and using a Windows 10 computer. My goal is to get completely stock with no evidence of root to be able to use apps that will not work on rooted devices. I have been unsuccessful in all attempts to hide root.
Has anyone else seen the same problems and did you solve them? Any suggestions would be greatly appreciated.
Hi, I've been trying to fix my H818N from the past couple of days.
Here is what I did to brick it, unfortunately
1. Downloaded Nougat 7.0 TOT file (H818P v29a TOT) from this website: androidsage lg g4 android 7 0 nougat firmware
2. Started my G4 into download mode and tried to load this TOT file using LG UP, however, LG UP stopped me by displaying an error message: Invalid TOT file
3. Then I used WinHex to change H818P to H818N in the TOT file and saved it
4. Now I was able to upload this file to my G4 in Refurbished mode using LG UP, the upload completed, phone rebooted and displayed: Erasing
5. After that it is stuck in download mode (If I restart it, it displays LG logo and starts download mode automatically)
6. In Download mode, my phone displays this at the bottom of screen:
U 633A s12. 0 AS10. 5 B100 UHS
S U LG-H818N 07.0 Hrev_10 .CPU4
H81529a
Here is what I did till now without any success:
1. installed the latest LG drivers, LG UP, and LG Flash tools on my PC
2. Tried to Flash the following firmwares using LG UP/ LG Flash Tool (I also extracted the dll file from each firmware one by one and placed in the model folder for LG UP while trying)
H815 V20o Modded.kdz
H818N10l_00_0113.kdz
H818N20f_00_0818.kdz
H818N20h_00_1019.kdz
H81520p_00_0403.kdz
H81820p_00_0314.kdz
Hong Kong H818N10b.kdz
H81520p_00_0314.kdz
H815TR20g_00_0428.kdz
F500K20C_00.kdz
All the firmwares get stuck at Internal command failed 9%, 11%, 24%
3) I have scoured the internet but wasn't able to find a solution yet
4) I even tried using the fastboot mode but unfortunately the bootloader is locked and I cannot erase the recovery or image
Now I'm not sure what else can be done to bring my phone back to life. I might try to get it into Qualcomm 9008 mode and try to unbrick it by following this guide: pakfones unbrick lg g4 hard bricked
Any help on this will be much appreciated

Modified KDZ link to downgrade from nougat to Marshmallow
https://mega.nz/#!BKRnDLIZ!K46qoXNhW...XJDd9MhuNdb-WA
Also please use this dll with LGUP.

In addition edit the downloaded file, with winhex, then do the normal procedure as you do before, thats all.
Good luck
