First off, I AM NOT copying Duckscreen's method. I've been using this method to flash firmware to my phone ever since trying to unlock it. He posted his method on "19th March 2014, 08:32 AM". I posted mine originally here: http://androidforums.com/optimus-l9-...ml#post6399062 on "January 20th, 2014, 11:51 AM" So do not call me a copy cat and don't tell me I stole his method but improved it. I got the MS769 firmware BEFORE the phone was released and before I even got my MS769.

Second, this guide is written to be noob friendly. If you do not take the time to read this post, I can't help you. I'm in college, I'm trying to find a job. I am also using correct grammar so Google Translate will do its job to the best of its ability.

Third, I do not make videos. If anyone wants to make a VIDEO (not words from this post on a .mp4 video file) go ahead, I'll probably update this post with a video if someone actually posts one, but it must follow this guide.

Fourth, there's no way to unbrick without Windows, stop asking.

Fifth, this will do a factory reset at the end whether you want it to or not.

Now, unlike everyone else I've seen posting on here, I like to keep things neat. Downloads at the beginning and instructions after. If you fail to read the instructions, not my problem.

Downloads:
Drivers: https://app.box.com/shared/32c5t7fj2w8xcwr0krjo
You need this to flash (READ THE README): LGFlashTool_L9.zip
And you need this to convert the KDZ to a BIN file: Download the attachment in the post
You will also need firmware.
MS769: http://csmgdl.lgmobile.com/dn/downlo...13/V10F_00.kdz (will add a mirror later)
P769: http://csmgdl.lgmobile.com/dn/downlo...21/V20H_00.kdz (will add a mirror later)
P760/769: http://forum.xda-developers.com/show....php?t=2107971 (Post 1 is Jellybean, Post 2 is ICS) (I don't have any direct links to P760 KDZ files.) If you want older firmware for MS769, I have V10b KDZ, but the site it is on right now is switching hosts or will be soon.

Instructions:
  1. Download everything from the Downloads section above if you have not already.
  2. Download firmware if you have not already.
  3. Extract all the zip files anywhere you can remember.
  4. If you can't figure out how to install drivers, you should have never rooted your phone.
  5. CONTINUE READING THIS POST.

How to extract the firmware from KDZ to BIN:
  1. Place the KDZ you downloaded in the EXTRACTED folder called "Place KDZ here"
  2. Open EXTRACT TO BINS.bat
  3. DO NOT OPEN THE BIN FOLDER. Doing so will throw an error and you will have to re-run the script.
  4. Once the BIN folder is renamed to the same software version as the KDZ file, you will see the single .bin file in there. Ignore the .dll and .fls files in that folder, we don't need them.

How to Flash the BIN
  1. There are 3 DLL files that came with the LGFlashTool_L9.zip file, find the model number that matches the firmware model number.
  2. After installing LGFlashTool (I hope you read the readme), open LGFlashTool, click "Select Manual mode".
  3. Where it says DLL, at the very right side of the blank white box there's a "..." button, click it and select the DLL that matches the firmware model number that you are about to flash.
  4. On the very right side of S/W, click "Add". Select the BIN file that we just extracted from the KDZ.
  5. DO NOT PRESS OK YET.
  6. Put the phone in download mode:
    Jellybean bootloader:
    Turn off the phone, remove the battery. Put the battery in, hold volume up+down and plug in the USB cable, after 1 second of the USB cable being plugged in, let go of volume down, keep your finger on volume up until you see S/W Upgrade. If you see the LG logo you failed, repeat the step again.
    ICS bootloader:
    Hold Volume up + down while plugging in the USB cable is the method I think.
  7. Now on the computer open Device Manager, go to "Ports (COM & LPT)". Expand it if it isn't already.
  8. Right click LGE Mobile USB Serial Port (COM#) and click properties.
  9. Go to the Port Settings tab, click Advanced..., change the COM Port Number to COM41. Press OK, press OK. You can close Device Manager now.
  10. Go back to LG FlashTool, press OK.
  11. Click this button now:

  12. Change it to look like this:

  13. Press OK.
  14. Click this:

  15. Now unplug your phone, wait 5 seconds, plug it back in. Let it finish. Do not unplug until phone is 100% booted.

Enjoy.

Thanks to @kuma82 this wouldn't have been possible without that script. Also thanks to @jes0411 @tog3 @Ilko and @navossoc especially for creating the original tools for extraction. I love LGExtract, it's my favorite program

Wanted to say thanks to Soflo Studio for helping me with this.

A very good option, thank you very much, sammyz.
The extractor doesn't work for me on W7 64b but works fine on a virtual machine running XP.
The main program works fine on W7 64b.

Worked fine for me on Windows 8 64 bit, try running it again and if you error, tell us so @kuma82 can fix it. @kuma82 I liked the old version where the folder wasn't renamed, it never error'd on me. This one error'd twice on me.

I think I know what's the problem. I edited that windows batch script on my phone. I'll make another script when I get a chance.

Give this one a try,
I ran the script a couple of times without any errors (on my Win 7 x64).
Don't forget to check the md5
"Extract kdz to bin.zip" md5 c063498bdbdf5492f64d51451c3fe396

Hi kuma82, first,thank you very much for your work.
I've checked the md5 and it matches, then tried twice and failed:

That's strange, it seems the windows built in extractor isn't extracting the cab. I'll have to throw 7zip program into the mix. It's actually a bit faster in extracting. Give me some time to modify the script.
