Hi everyone,
I got F240L for about 2 months.
Got software problem last months from a post http://forum.xda-developers.com/showthread.php?t=2380374
Repair to some phone shop, he got no clue neither. Left my phone in CWM.
So, I use KDZ Updater + download KDZ file from pan.baidu.com (get it to work again).
I got curious, so I install Dungeon Hunter 4 again. Again, software problem occurs, even I uninstall the game. KDZ Updater and LG Mobile Support Tool left my phone stuck in U+ LTE logo.
Browse the web, then I read someone whose using LG Flashtool (it need DLL and TOT file) to flash the phone.
Search those two files every web, finally got it.
LG Flashtool step by step guide http://forum.gsmhosting.com/vbb/f177/lg-flash-tool-free-no-need-b2b-user-pass-1628819/index2.html
And got LGUP_GKV.DLL from extracting F240L10t_00.kdz from pan.baidu.com (see attachment), this file has the same size for F240K and F240S, so it must be compatible for F240L, F240S, F240K.
And got TOT file from http://www.gaojituan.com/thread-90-1-1.html or http://optimusforums.com/threads/f240-optimus-g-pro-firmware-downloads.7679
I hope this solution might help someone who ever got this problem.
NB : After 600 seconds flashing progress using LG Flashtool, don't put your phone in LG SOFTWARE MODE. Somehow, the phone got it reboot in DOWNLOAD MODE, and LG Flashtool will reflash your phone for the 2nd time (start from 1% progress again).

has anyone started to jtag fix the hard brick yet ??
Hard brick issue
Sorry, I'm also a noob here.
Can your phone go to DOWNLOAD MODE ?
I read on hongkong website (got it translate from google) 2 weeks ago, someone already try LGNPST, KDZ Updater, R&D Tool, LG Mobile Support Tool, still didn't work. The other guy recommend that you should have it fix by LG guy in Korea, or use JTAG device.
I even don't know what JTAG device is.
Maybe someone in this forums can explain you how.
Sorry if my word can be misleading.
I'll update the thread to delete the word "Hard Brick"
You are a wonderful and creative
It has succeeded with me
Glad could help.
In the mean time, enjoy this super AWESOME phone.

Could you please provide instructions on how to use KDZ updater? Where did you download it from or if you could PM? thanks
I'm downloading software via LG Mobile support but at the moment its going to take 30hrs!!
KDZ updater & LG Mobile Support Tool won't help.
You need to download LG Flashtool 1.5 is the latest version on the link that on #1 post. Once you download, follow the procedure how to install the LG Flashtool.
LG Flashtool needs 2 files (DLL & TOT) to flash your phone.
You can download DLL file from the attachment on #1 post. The attachment is compressed in RAR format. You can extract it using Winzip, Winrar, or 7zip.
The TOT file is on the 2 link #1 post (chinese website & optimus forums). You need to download the approriate type according to your phone (F240L, F240K, F240S) each files about 2 GB size. I suggest you use any download manager, to prevent disconnect from bad interference or time out. I can't post the TOT file here too due to slow network in my country (Indonesia) .
After you collect those DLL & TOT files, here's step by step :
1. Disconnect any internet connection
2. Set the computer time before Juli 15th, 2012 ( I set March 1st, 2012)
3. Double click LG Flashtool. Username, password, and Registration key are on the link #1 post
4. Insert DLL file in DLL column. Browse to where you put the DLL file.
5. Insert TOT file in Software column. Browse to where you put the TOT file.
6. Click OK
7. Click the GEAR icon, set only port #1 that ticked. Other ports are UNTICKED. Click OK.
8. Press & hold volume UP and DOWN, while connecting the USB cable to your computer (set to DOWNLOAD MODE). Until the phone shows "DOWNLOAD MODE" on the center of the screen.
9. Open System Properties. Set COM port for LG Handset using port 41.
10. Click Arrow Right in LG Flashtool, disconnect USB cable for 5 seconds. Reconnect USB cable.
11. The FLASH process in progress, wait for 600 seconds and shows green background say "PASS".
12. Disconnect USB cable and close the LG Flashtool application.
13. Release the battery, wait for 3 minutes.
14. Do FACTORY RESET in SETTINGS. End of FLASHING process.
Enjoy !!!
Thanks for that very clear instructions.

PLZ TELL ME HOW CAN I DOWNLOAD TOT FILE baidu is not working
You can download from http://www.gaojituan.com/thread-90-1-1.html or http://optimusforums.com/threads/f240-optimus-g-pro-firmware-downloads.7679/
Click on the latest TOT file according to its date and your phone (F240L, F240S, F240K).
I've test on F240L v10i from http://www.gaojituan.com/thread-90-1-1.html works very well on pan.baidu.com.
Which file are you try to download ? Which phone do you use ?
I tried the procedures you guys mentioned above, but my phone does not seem to be being flashed.
Everything seems alright, up until disconnect the USB cable and wait for 5 secs to reconnect, but after reconnect, nothing happen....
mine is F240S, does it matter? How do I extract DLL from TOT or KDZ files?
Thanks in advanced
Dennis
---------- Post added at 11:01 PM ---------- Previous post was at 10:23 PM ----------
I actually finally got it flashed, all the procedures are correct, just need to time that 5 secs accurately.
Also, anyone with F240S needs to stay with the version of Flashtool that OP provided, any version higher than 1.4 seems giving me error.
Thanks very much for the info.
Dennis
Please help...
Guys plzzz help... I have F240s. first i was rooted on stock and then flashed cwm along with loki patch file (easy-cwm-f240s.zip file). i wanted EDGE on my

rom from CWM but still no signals ( mobile model was still showing up e980h from panama rom) then i factory reset and flashed Cm 10.1 of f240s (i think i may have wiped system ,cache and date before it). now when i power on, LG logo appears on screen and in left top side it says:

I Have used a battery stand charger to charge for 3 hrs but after checking phone software setting for 3,4 minutes it still says the same thing about battery again n again. should i let it charge to 100% no
matter how long it takes and then try or do something elsee... plzzz helppp

*On will crackers xda link(https://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091) he mentions: "With windows 64 bit you need restart pc then click f8 choose disbable driver singturne..." Did you try that?
*In the files you extracted from the tot look and see if there is a .txt file listed; if so remove it from the folder and try loading the extracted files into the tool's folder again; I believe that file is a directory for the partitions so you may have to put it back in that extraction folder after after you get the partition files loaded into the tool.
This work for me
Hold down SHIFT key and right click on a running program icon on the taskbar, a popup menu should appear, click on Move then use the Left/Right Arrow key to move it.
Do the same for the rest of the running programs.
Let’s see if you can at least get them to move over, then we’ll see if other apps follow suit...

sorry you had problems
the error is one of the drivers lg
you should plug it into one of the main USB ports on your PC.
or rather entering device manager and re-assign drivers to ports.
Have you downloaded the lgup for lg g3 and g2?
Drivers are installed, USB debugging is enabled, LG PC Suite OK.not sure what else there is missing.
Download : lgup-g2-g3.zip
Solve it FIX
good after I found the problem LGUP
roms apparently change the model of the device as it changes cm11 to build Cyanogenmod 11 xx
AOSP - to AOSP rom 2 etc.
the solution would be to install a stock rom clean no matter if v10 v30 etc. The important thing is not having changed the model number and manufacturer.
I hope I have helped and sorry
that includes cloudy fa's roms

Hi !
How do I do all the above ?
My PC recognize the phone without problem, but LGUp won't start unless I "select a known model"... (LGUp window shows : Model = Unknown ; COM Ports = [COM5, CloudyG3] )
Problem is that my phone is softbricked after installing a new ROM, and I can only enter download mode (not even recovery). I just want to downgrade it and reflash a LG's stock ROM (or whatever ROM that would make my phone actually work !!! )
Can you help me do that ?

LGUP "UNKNOWN" and FlashTool failure with LG G3 (and possibly others)
When I downloaded and installed LGUP with the DLL installer stated to be for the LG G3, the program did not recognise the phone, reporting it as "UNKNOWN". The LG FlashTool also failed, reporting the IMEI and PID as NULL. After spending a lot of time on this, I twigged that the DLL file in the LGUP model directory was for the 8994 processor; but the G3 has an 8974, quite different and incompatible. I located the DLL installer MSI file for 9874 devices, uninstalled LGUP and the DLLs from Windows add/remove programs, ran the 9874 DLL installer and reinstalled the LGUP program, and everything worked.
The file is, amongst other places, on https://uptoandroid.com/download-lg-up-tool-for-lg-smartphone-latest/. Do not download DLL files for LG G4, LG V10, LG G3, LG Stylo, filename LGUP_Common_DLL_Ver_1_0_28_5 .msi, but instead For LG phones based on Qualcomm Snapdragon 800 MSM8974 SoC, filename LGUP_8974_DLL_Ver_0_5.msi:.

23 Aug 19: I find that I've rediscovered the wheel. Exactly what I said was posted in 2016 - if I'd found it, it would have saved me a lot of time!
Hello Guys
My friend ask me for get a Lineage OS to his H815 with Nougat. I agreed as I made few successful changes from stock to Lineage OS with Samsungs and older LGs (like L3 E400). But G4 is really more complicated, more than I expected . Firstly I wanted to unlock this phone with FWUL, so I download a VirtualBox emulated image with FWUL and after it boots I opened SALT program and it detects the phone. I made a basic backup and then I choosed Unlock G4 (UsU). After that some windows pop up. Last window was a pre-checking, when the bar gets to the end window closed and nothing more was happening. So after almost hour of waiting I just turned off the phone - I thought its all. After that while phone is booting I have those messages in the left top corner:
[820]-----------------------
[870]
[920] Secure boot error!
[970] Error code : 1009
[1020[ OFFICIAL !!
[1070]
[1120]-----------------------
Its booting, but only sometimes its normal boot, most starts are with bootloop, sometimes its start after 10 restarts, sometimes after 2nd restart, sometimes after plug in/plug out USB cable it starts boot normally (connecting cable only to phone, not to PC), sometimes only thing that helps is to take out the battery. I made full wipe to be sure that its not a software problem, but only thing I achived with that is fact that phone has a Nougat and now it have a Marshmallow. It is (was?) H815, but now model name is LGLS991 (?), it gets very long until it shows software version (V20g), IMEI is unknow, even when I type *#06# I get the null response.
I can get into recovery, can put phone into download mode. But i'm not able to do anything to get LOS or a least Nougat.
I've read many, many tutorials how to get G4 working properly after unsuccessful unlock, but nothing helps. What I've tried:
1. Flashing stock Nougat for H815 with LGUP, installed USB drivers, proper DLL, set com to 41, but when I trying to flash, after a 4% i get error: KDZ file is invalid. Downloaded few KDZ firmwares, dont belive that every single one is invalid, there is something wrong with LGUP or with settings, but I cant find what
2. Flashing with LG Flash Tool 2014: tried both normal flash and cse flash and always stoping in the same moment, with "Connection to server failed. Try again in a moment". Read many tutorials about this error, none was helpful in my case.
3. Flashing with LG Flash Tool v1.8.1.1023 and a TOT file, but after select of dll and tot file and press the yellow arrow I get an error: "Failed PreviousLoad()"
Tried all this methods on second computer but without a luck.
What else can I try to get this G4 working properly? Maybe try to install some rom from stock recovery? But which rom will be ok and dont get things worst?
If you need more info dont hesitate to ask. Would be very greatful for any advices .
you definitely didn't read enough... go to read again the UsU thread and as you've read the whole tutorial, you can also read the whole FAQ and the OP, because 90% of what you pointed out in your publication (which incidentally is in the wrong section) is explained there.
A quick advice: Don't try to flash any KDZ/TOT again.
