EDIT: LG update will not run because it says "Please install CSMG B2C Client Tool" "Select tool ->B2C Client setup menu"

it took me many tries and several hours, but I finally got it. be patient and keep trying. what I found out is, when replacing bin6, you have to open the C: program data/lgmobileax/phone folder. watch as the files get copied. once bin7 goes in, copy the downloaded bin6 in. Windows will pop up asking you to replace. click yes, and it should root.

[LG Optimus L9 P760, P765, P768, P769] dismantlehands:
As stated by artit in my thread I "was" having problems flashing via windows 8. I fixed the issues by running every exe in windows xp sp3 compatibility mode and in administration mode. cmahendra suggested i use that method after figuring it out on my own. Another problem I had was trying to use my usb 3.0 port, the blue labeled port on my toshiba laptop. For some reason it wouldn't read and write in S/W mode on that specific port. usb 2.0 seemed like a better solution, so i switched ports and tried again. I am now currently flashed and everything is working fine.

I hope you get rooted, i've deleted a bunch of stock apps. The phone runs really smooth, now I play the waiting game with a jb rom or cyanogen mod with working camera and wifi.

Uninstall drivers and all LG related apps. Restart computer, Start from step 1. You may be having corrupted or clashed drivers.

Your problem description is not clear but good you solved by going back. But for going back also you might have used same flash method. check again may be answer is somewhere there. Start afresh.

Make hex-edited BIN for P768E kdz separately. They are not swappable. In fact bin files posted here are extracted from respective KDZ only. You should not swap them. They are part of huge 1GB+ bin file.

Off topic, but its already released. Flash CM10.1 on P765, works well without problem. (P760 and P765 are compatible to each other)

Lelus methos works on all L9 variants inlcuding P768 but only for ICS, not for JB. Many have confirmed this rooting before. If you know what offline flashing means and can do some copy-paste actions quickly you can flash P768 too. :D

@ALL

ATTENTION: THIS ROOT METHOD WORKS ONLY ON ICS, NOT ON JELLYBEAN.

1) First unlock your P760 and P765 with the help of this post. Then...

2) Go here for JB Root on Unlocked Phone

Even P768 users can unlock the Bootloader and flash JB, but camera wont work.

JB is not yet released for P769 until this post is typed.
[LG Optimus L9 P760, P765, P768, P769] artit:
This guide works on all L9 ICS. If your phone isn't root after flash so... You do some step incorrect. It can be

1. .bin file you edit is incorrect. For early kdz it's in [5], new update in [6]. Don't know what KDZ you want to flash?

2. Make sure that your next .bin file appear before you replace .bin with your edited file (if you edit [5] next file is [6])

In other steps you just run scripts, so your mistake must be in 2 steps above.

for those having problems installing the kdz files Delete all the flash stuff and extract rootflash folder to C:\Rootflash . After you've done this go to C:\Programdata and delete the LG folder completely. Restart. Start small server from C:\Rootflash\https as administrator. Start the flashing program again. Tools>Install b2capp. After this it should go as planned" tablechair helped me with this in another post.

I QUOTED WHAT TABLECHAIR DID AND IT HELPED ME ADVANCE IN THE ROOTING PROCESS AFTER THAT FOLLOW THE NEXT STEP OF CMAHENDRAS. ONE THING FOR SURE ONCE YOU DELETE THAT FOLDER ITS GOING TO REAPEAR ONCE AGAIN WHEN YOU PRESS TOOLS>INSTALL B2CAPP WHICH IS GOING TO INSTALL SOME STUFF THAT WASNT THERE BEFORE AND BECAUSE OF THAT YOU ARE UNABLE TO ADVANCE TO INSTALL THE KDZ FILE.

ONCE YOU ARE ABLE TO ADVANCE AND FOLLOW THE STEPS OF FLASHING THE KDZ AS IN THE PICTURE OF THE TUTORIAL FROM CMAHENDRA YOU WILL SEE A NEW WINDOW WHERE THE LG UPDATE TOOL IS GOING TO "DOWNLOAD FROM THE SERVER " YOU ARE GOING TO OPEN C:\ProgramData\LGMOBILEAX\Phone ONCE YOU SEE THAT THERES SEVERAL BIN FILES OF DIFFERENT NUMBERS SHOWING UP AND YOU SEE THE BIN(6) THAT IS THE ONE THAT YOU DOWNLOADED YOU SIMPLE COPY THE DOWNLOADED BIN AND PASTE IT THERE A WINDOW WILL SHOW UP IF YOU WANT TO CONTINUE TO REPLACE THE ONE THAT IS IN THERE ONE IT IS REPLACED JUST SIT AND RELAX AND WAIT UNTIL THE PROGRAM FINISHES THE PROCESS AND LET IT REBOOT THE PHONE AND WAIT UNTIL IT REACHES 100%.

Hello!

First of all, i would like to thank you for your work. It has given my phone new life :D

Second, I am here because i need your help. Some time ago, I used the tutorials here to upgrade from ics to jb using KDZ. All good, but Sunday i decided to reset my phone because it was working a bit sluggish. I booted into recovery, made a backup of course and started to wipe cash, factory reset, the works. After i rebooted, it remained stuck on LG logo. Good, i tried to restore backup - it did the same thing. As i was in a hurry, i quickly flashed a custom ROM (aokp) from here and went on my way. The problem with those roms is that they are not yet fully functional and i really need all the features of the phone to work. So i tried to flash factory KDZ using this tutorial. Bear in mind that I have some experience in ROM flashing and related stuff as i have android phones for many years and i”ve always tested custom roms on them, repaired from bricked state and so on.

But this one has got the best of me. I run windows 8 on my laptop, so i did all the operations in parallel on a windows 7 computer just in case there would be a problem. I did all you said, step by step, verified all the drivers step by step. Anything I do, i end up at 15% upgrade when the LG Software says that cable is disconnected. I”ve read your post ten times still no success. Anything I try it takes me to the same spot. Are there any drivers that you suggest and aren”t mentioned in this thread? Any workaround for this?
