Cant update my LG G3 - G3 Q&A, Help & Troubleshooting

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.

[Q] No dll & tot files for f240x devices??

Hi I'm a noob who just bricked my F240L (korean ver.):crying: I somehow wiped my system partition and the result is disastrous; KDZ flashing is impossible via R&D / support tool and I can't even get into the recovery mode. Only download mode is available.
I heard that it could be fixed by using NPST but I only can find the files for E980 at
http://forum.xda-developers.com/showthread.php?t=2272177, not 240x series. Moreover, KDZ files for OG Pro cannot be extracted by using LGExtractor so there is no way I can get this file by my own.
So is there any possible way for me to get those files??
-------------------------------------------------------------------------------------------------------SOLVED----------------------------------------------------------------------------------------------------------------------
How to solve it ? I'm also having the same problem
I got the same problem also, mine is F240L (Korean version)
The differences is I can manage to enter CWM, but the CWM can't mount external SDcard. As if my MicroSD doesn't exist.
I got no backup file to restore via CWM 6.0.3.3.
Using R&D Tool to flash, after 10s update process. Appear error message "Insufficient Battery Level to Proceed", that's strange because the battery is 100% full.
Using KDZ Updater, the error message appear "File Extracted Error" for 2 KDZ files I got (10T and 10V).
Hard Reset didn't solve the problem.
Now I'm stuck in DOWNLOAD MODE and CWM 6.0.3.3 (can't do anything in CWM).
Before entering CWM, there's an error message "Secure Booting Error ! Cause : Device Unlock, so Boot success !"
Please, anyone would be so kindfull to HELP.
@stupididiotism can you explain how you solve it ?
@chimmot307 have you ever tried this version to flash (translate from chinese)
so my phone was bricked (only download mode available) 1hour ago:
go in download mode->install LG support tool->in menu go to "customer support"->"recovery phone"->(your imei should be here or enter it if not)->click check
and now wait it download the whole img and flash it for you
The firmware 10T in baidu.com is broken, asking for username and password to resume. Little HELP with the username and password, fellas ?
I follow your advice go to "customer support"->"recovery phone"
After 10s update process. Appear error message "Insufficient Battery Level to Proceed", that's strange because the battery is 100% full same with 2nd battery whose 100% full also.
It seems LG Corps. tried to block anyone outside Korean to update their phone (I live in Indonesia, got this phone from real Korean people who sale this phone in Indonesia illegally, because Indonesian market is E988-16GB storage compare to F240L more spacious).

Following your 1st advice, I managed to download the KDZ from baidu.com, and run the tutorial step by step. Everything runs smoothly.
Thanks in advance @smaybe. I owe you BIG one.
:good:
For those who got stuck in DOWNLOAD mode, you can follow these steps (in attachment).
LG PC Suite won't recognise my device (in DOWNLOAD MODE), it only recognise when in LG SOFTWARE MODE (Settings => PC Connection => USB Connection Type => LG Software).
So I can't go to Device => Firmware Recovery.
Why did you delete the 1st advice, @smaybe ? Totally recommended.
hi guys
I was in the worst condition : wiped system partition and moreover, I hard reset my 'rooted' phone.
Recovery mode not supported and kdz flashing also not working.
Then I found this divine tool called 'LG mobile flash tool v1.5' and I could find the tot and dll files for F240 series from some china website (I paid for that tho)
So my point is if anyone holding F240L and having the same problem as me. Then I can send you the files. I feel like posting the file here is a violation of intellectual property of the chinese devleoper(?! what am I saying?)

It's strange I will look after work but for me it recognise even in download mode
I deleted because I thought the last solution is easier i will take it back
LG PC Suite sucks
I've updated to the latest version, it still doesn't recognise my F240L (in SOFTWARE MODE), it said "Need to change with the right cable" even when I swap with different USB cable.
Or maybe my Windows 7 Ultimate (64bit) having problem in compatibility with PC Suite that won't recognise the USB. Cause, I haven't try with different operating system (Mac, or Windows XP)
Stuck in U+ LTE Logo
Dungeon Hunter 4 messing my Optimus G Pro in this thread http://forum.xda-developers.com/showthread.php?t=2380374
So I decided, to wipe system & data partition.
Hope that KDZ Updater will bring it back normal the way smaybe told me to.
KDZ Updater show 100% Finished, but my F240L still stuck in U+ LTE Logo.
So I try new LG Mobile Support Tool, Upgrade Recovery => IMEI=> OK. Updating to 1.69 GB, 100% finished, still stuck in U+ LTE Logo.
I haven't try LG Mobile Flash Tool 1.5, maybe stupididiotism could tell me step by step ! And not to forget to send the TOT & DLL files.

LG Flashtool Error Message
I run LG Flashtool according to website http://forum.gsmhosting.com/vbb/f177/lg-flash-tool-free-no-need-b2b-user-pass-1628819/index2.html
Extract F240L10t_00.kdz from Baidu.com, got 2 file :
- LGUP_GKV.dll
- F240L10t_00.dz
So I used those 2 file in LG Flashtool ( I don't know if those the correct files to use in LG Flashtool, cause I can't seem to find DLL file for F240L, but I think for S/W file is correct ).
Used port COM41 to flash (DOWNLOAD MODE is activated on F240L). Then I unplugged the USB cable for 5s, and replugged it. Error message appears as follow.
Am I using the correct DLL file to flash ? If not, would you be so kind to upload the DLL so I can flash my F240L ?
Thanks.

LG G4 H815 stuck, download mode only, no adb

Hello hello,
I unlocked bootloader, installed TWRP 2.8.7.0 (adb -> fastboot method) and then I flashed SuperSU 2.46 zip. After reboot from TWRP my phone stuck.
I can't access TWRP or i don't know how to…
System isn't starting BUT sometimes after few minutes of seeing LG logo i see standard wallpaper and suddenly animation freezes. That's all.
When i go to recovery mode (voldown+power, release power and press power again) I can "do" factory reset. I choose 2xYES and i see green android. Then phone is restarting but i should enter to TWRP, right?
I tried to flash stock system (kdz, tot, dz) via:
- LG Flash Tool 2014
- LG Flash Tool 1.8.6.527
- LGUP
- LG Bridge
but nothing…
My phone PID and IMEI is null :/ (and "CUMSS" to :?)
I tried fix that with QPST (2 different versions) but in device manager my phone is only detected as COM port. No "Android Device". I can't read and write anything…
adb isn't working
I tried all USB 2.0 ports, different drivers, roms (even not for 815), dlls.
I fought 3 days and still have brick, not smartphone
I have only download mode working.
I can send commands to com port (Send_Command.exe) but sometimes nothing happen, sometimes i see "fail" after sent command.
Any ideas? Can I install recovery through download mode? Or maybe somebody know how to send files to phone in download mode but without adb?
I had stock rom MM V20L. What else you need to know?
Thanks for any suggestions, sorry for chaos in post and my english.
After trying different roms in different programs with 3 versions of dlls and different drivers…
I found solution: just reinstalled .NET Framework and then finally i flashed by LGUP (refurbish, v20L, kdz, dll 0.0.3.23)!
Welcome back H815

Help required to go back to full stock (remove TWRP etc.)

Hello,
I have Fulmics and TWRP installed, but I want to go back to full stock and official recovery. I have a back up of my original ROM, but no back up of the stock recovery (I don't think anyway... what partition is the stock recovery on?).
How do I replace TWRP with the stock recovery? I have looked at various threads but most of them seem to be out of date or not quite the same situation.
Any help would be greatly appreciated!
Thanks
b

m
p
Solved it myself (after multiple hours spent researching, trying different methods and temporarily soft-bricking my phone...)
As a brief summary for other people:
Download LG Flashtool 2014
Download LG G3 Drivers
Download correct KDZ file from here
Downloaded the Megalock.dll and put in Flashtool folder.
Put G3 into Download / Firmware Upgrade mode (Power off, hold volume up button and connect USB cable to PC)
Go to Device Manager in Windows, find 'Ports (COM & LPT)'; go to properties of the LG Serial Port, 'Advanced'-> and change the COM port to 41.
Run Flashtool.
Select KDZ file.
Click on 'CSE Flash'
Click 'Start'
Change language.
Click OK
Wait while hopefully it installs the ROM on to the phone and then reboots.
Sorry it's not more detailed!

firmware update do not....lg g4 h815

I will be simple, after installing this room
https://forum.xda-developers.com/g4/development/h815-nougat-stock-t3659860
, I had a problem, ie I had more access to the recovery mode, then I wanted to install marshmallow but the phone remains blocked on
firmware update do not unplug the usb connection until the process is complete...
even when I remove the battery and then I turn on the phone it remains locked
Screen:
http://zupimages.net/viewer.php?id=17/37/z8va.jpg
i think you didn't install any Nougat bootloader and modem before flashing the rom
In TWRP wipe everything, then flash Nougat Bootloader and modem (this file) from TWRP:
https://www.androidfilehost.com/?fid=745425885120759121
and only after install Freedom Rom:

Ok try with LgUP
1) First install Lg Bridge (for LG usb driver) HERE
2) Then install LG UP HERE (both LGUP_Install_Ver_1_14_3.msi and then LGUP_8994_DLL_Ver_0_0_3_23.msi)
3) After download THIS and copy these 2 .dll here C:\Program Files (x86)\LG Electronics\LGUP\model\8994
Download a .kdz LG G4 firmware like this 20d HERE
4) GO in Download mode with your G4
Plug the USB Cable into the PC(not connected to the LG G4)
Have you PC Powered On and Logged in
Power Down the LG G4
Press and Hold the Volume Up Button on the LG G4
While Holding Volume Up, Plug the USB Cable into the LG G4
Continue Holding the Volume Up Button After You See ‘Download Mode’
Let Go of the Volume Up Button When You See the ‘Firmware Update’ Screen on the G4

5) and following the indication you need from this post
TO DO A FULL WIPE AND INSTALL MM
1) Open the LGUP on your computer.
2) FILE PATH point it towards the MM KDZ (LgUP will see only .tot, so when you browse and search your .kdz pay attention to change in the menu .tot to *.* to see everyfile you have)
3) After you load the .kdz now shut down LGUP!
4) Now open LGUP again - you will notice that the MM KDZ will still be showing in the FILE PATH section.
5) Select REFURBISH and make sure BIN file is ticked. Press Start. Make cup of tea and be patient

I have tried to flash the 20d version a couple of times but no luck with that so I tried the 10b version still no luck and ending up with the same error. So I decided to give it another try with H81520p_00_0314.kdz and guess what, it flashed and booted up and installing apps now.
I have not been able to download the file, every time I have this error message that appears:
