This case is very simple to solve. When you try to install a custom recovery with your bootloader locked, the phone system detects it and give you a message of an error in security, like in your case. To solve this, you'll need to reflash your rom. By doing this, the KDZ will reflash the original recovery and you will be able to access your phone/recovery again.
Step by step:
1. You need to install fastboot drivers: http://forum.xda-developers.com/showthread.php?t=2119090
Turn off the phone and remove the battery. Download THIS and exctract it to C:/. Open device manager in windows (Rigt click on Computer > Manage > Device manager) and connect your phone without the battery to pc via USB cable. Look in device manager for a new hardware connected, right click on it and click in update drivers. In the window open, select "Search for software driver in the computer" and in the window open select insert C:\fastboot\usb_drv_windows, tick the option "include subfolders" and advance. A pop up window may appear asking you if you do want to install the driver, choose YES and the drivers will install.
2. Navigate to the folder you extracted (C:/fastboot) and double click on start.bat. It will ask you for administrator privileges, just say yes.
3. Select your phone model (2 for P760, 3 for P765, 4 for P768 and 5 for P769). It will ask you to turn off your phone and remove battery. When you done with that, press enter. It will now ask you to insert USB cable with the phone without the battery and after 4 seconds re-insert the battery. Onde you done with that, it wil return a message to press any key. In this step the fastboot drivers may be installed again. Don't worry, it's normal
4. Remove the battery again, wait a few seconds and re-insert it.
5. Plug the USB cable in the phone with the battery in and let VOL UP pressed. The phone will enter in SW Update mode.
6. Follow THIS to reflash your rom. A list of avaiable official roms of different models is HERE. Remember to only flash roms made for your phone model or you may get some issues.
7. You're all done I recommend using THIS TWEAK, the phone becomes more responsive.
*** If you flashed a JellyBean rom (V20X.kdz) you can easily root with THIS and if you want CWM recovery use THIS ONE ------ REMEMBER NOT TO FLASH ANY CUSTOM ROM WITH THIS RECOVERY BECAUSE I'M CONSIDERING YOUR BOOTLOADER IS LOCKED AND FOR THIS REASON, YOU CANNOT FLASH CUSTOM ROMS WITH CWM, IT JUST DOESNT WORK!!!
Hope it help you
It works!!

Thank you so much. Yes my P769 BOOTLOADER definitely is locked and I can't even root it with all methods provided in xda, I use exactly your method to get my L9 back to life -- although I have to flash it back to original stock but at least it's BACK! Thank you so much. I saw some other people have the same issue but they can't make it work, hopefully your answer shed the light to ALL!
security error just use the lg pc suite and remove the lines or the host put recover via recovery and put your imei and it will start to download the stock Rom

I tried this method and the offline kdz method and here is the trouble I am having.
1. With this method I do everything perfect the device shows up for a couple seconds then it disappears so I cannot go any further.
2. With the offline fix I followed the OP to the letter and when I get to the part where I click on "normal web upgrade" I open it and start the upgrade as stated in the OP and nothing. I get the retry or cancel internet warning and ignore or close it and it will not even try pushing the file.
Anyway I have tried 2 different machines to no avail I am wondering if anyone has had a similar problem and fixed it?

Didn't work for me! But I tried another method and that saved me from a lot of steps.
Just install the driver and the latest LGMobile Support Tool
Start your phone in Software upgrade mode... Power + Vol up
In the LGMobile Support Tool click on Options and then Upgrade Recovery
Put your IMEI in the option that pops up
Wait for the miracle!
It worked for me ... NO MORE LG SECURITY ERROR

cant install fastboot drivers windows 10

I've been trying to flash my p768 for JB V20A VIETNAM. i used V20A TELCEL, MEXICO Before this flashing.
So I started flashing the KDZ file, followed all the necessary steps and finally when the process is at 15 percent, flashing stopped saying there is a problem with communication between cell phone and pc.
So i did the workoaround, remove the usb cable and wait for at least 10 secs and reconnect, then waited for all the drivers to install. After restarting the whole process it got stack still at 15 percent. Now I cannot get out of Software update mode even if I remove the battery and start the device again.
also i use Following method. and it dosent work. and at 15 percent, flashing stopped saying there is a problem with communication between cell phone and pc Again.
method:If you were on JB, the phone won't be recognized on "S/W Update" screen by the offline method. You must use the online method :
- Remove the lines you put in your "hosts" file ("127.0.0.1 csmg.lgmobile.com" and "127.0.0.1 csmgdl.lgmobile.com") then reboot your computer
- Connect your phone (on the "S/W Update" mode)
- Directly start "B2CAppSetup.exe" : it should detect your phone
- Click on "Customer Support" then "Recovery Phone" (see screenshot on http://forum.xda-developers.com/show....php?t=2217710)
- Wait and pray... It can be long because it downloads the last KDZ file from official LG servers.
plz help meeee

hard/factory reset your phone ; turn it off, press vol- & home & power on
remove all lg drivers and software etc, reboot pc and install lg pc suit , try recovery from there

The LG Update Tool can install latest drivers for you: did you properly install them ? If your phone can start in "S/W Update" mode, the online unbricking method should work, that's why I think you have a driver issue. Did you also try on another computer with another Windows version ? (the most "driver friendly" version would be a Windows XP at least on SP2).

you need to install fastboot drivers twice, once before you run the omap4fastboot and again after running it when you see that mirrored fastboot text
I decided early this week that i want to have a custom ROM on my phone, so i followed this guide http://forum.xda-developers.com/showthread.php?t=2277639 and i managed to get the eu kdz with root (hex edited bin) on my phone so I will be able to unlock the bootloader, so after waiting half an hour as instructed, I typed the command adb reboot oem-unlock but the phone just booted normally and i didn't see the prompt for unlocking the bootloader, so i thought that maybe it was because i didn't have the T-Mobile radio installed, so I installed the recovery installer and clicked install recovery, and it said install successful, but when i hit reboot recovery it just booted normally and did not boot into recovery, and when going back into the app when the boot was completed i noticed that it said recovery not installed.
now just to make things easier with the whole mirrored mess, i thought that installing the touch drivers for my P769 might help, so i followed these instructions
enter the following commands but before you must put the v6.bin file to your external sd card it is in the downloaded files after you have put it to the root
of your external sd card enter the following commands
"cd c:\Android"
"adb shell"
"su" when you enter this go to your phone and accept the su request
"cat /sdcard/external_sd/v6.bin > /sys/devices/virtual/input/lge_touch/firmware"
after you entered the last command you need to close that command promt and open
another one and type the following commands
"cd c:\Android"
"adb shell"
"su"
"reboot" then it will reboot and the touch will corectly work remember the mirrored problem will continue
Click to expand...
Click to collapse
but i guess that was meant only for the T-Mobile kdz and not for the EU one that i had installed because when i rebooted the phone the touch screen wasn't working at all.... so i thought just to flash back the original T-Mobile kdz and then flash the touch drivers again, but i couldn't change the usb mode to software mode since the touch screen isn't working, and when going into SW update mode by pressing vol up and connecting the usb, the update process stops at 15% saying my phone isn't connected...
so at this point i pretty much gave up in root i just want my phone to work normally again... :crying:
can someone please tell me what to do to get the touch working, or some other way to get back to the T-Mobie kdz?
THANKS:laugh:

1. Please read http://forum.xda-developers.com/show....php?t=2411265
or
2. Use LG mobile support tool to recover your phone
- Boot you phone in S/W upload mode. To do this, turn off your phone, take off battery, hold down vol- button while re-connect ubs cable wait about 5-8 sec. After S/W update screen appear insert you battery. (You may need to install LG usb driver first)
- Open LG mobile support. (if it's not installed, search for it and download from lg site, http://tool.xcdn.gdms.lge.com/client...2CAppSetup.exe)
- LG mobile support should show your phone info
- Select Customer Support > Recover
- And wait for program to download and flash your phone (1 - 2 hours)

i know the old version has the customer support option, but the new one doesnt and it automatically updates on start up.
So I recently wanted to load a custom rom on my p769.
Unfortunately, I tried to flash a rom without actually having the bootloader unlocked (thought i did?)
Now i'm forever stuck at the "LG Security Error" screen.
I can't seem to do anything else! :'(
The only other mode I can boot into is S/W update screen (holding volume up and plugging in usb cable).
I tried to get to another mode I read about (vol up + vol down then plug usb cable for "download" mode, to no avail)
Anyway, once I do get it into sw update mode, I can't seem to do anything either way, when i try to list adb devices, none are listed, when i try to use lg mobile tool, it never connects, when i try to use kdz offline update tool, it doesn't see the phone, it just keeps trying to connect, the log freaks out at "_IsConnectedPhone Call", and just keeps trying to "connect" to phone but can't
Am I totally screwed here?
What can I do? Any help appreciated!

I tried to get to another mode I read about (vol up + vol down then plug usb cable for "download" mode, to no avail)
Anyway, once I do get it into sw update mode, I can't seem to do anything either way, when i try to list adb devices, none are listed, when i try to use lg mobile tool, it never connects, when i try to use kdz offline update tool, it doesn't see the phone, it just keeps trying to connect, the log freaks out at "_IsConnectedPhone Call", and just keeps trying to "connect" to phone but can't
Am I totally screwed here?
What can I do? Any help appreciated!

You're on JB, right? KDZ offline flash tool cannot detect phone in JB. you have to flash ICS x-loader/u-boot then that tool can detect your phone. please visit http://forum.xda-developers.com/showthread.php?t=2292828
For LG mobile support tool problem, it need to download rom from LG server. Have you remove/comment 1-2 line that you add to hosts file? You said it never connect that mean it don't see your phone?

I've tried this as well, but I don't know if i'm doing it correctly
I installed the 'drivers' it needs (following the readme file) when it shows the "unknown/other" device (the part where you have to catch it in device manager).
After this, I run the start.bat, enter 5 and hit enter, i unplug my phone and hit any key, then i plug it in as it says and it does it's thing, then i wait for 4 seconds when it begins to say "waiting for device", i put my battery in and it just stays there, waiting for device
Can you help me figure this out? Am I doing something wrong?

i think i'm making some progress, thanks for helping so far!
anyway, i'm able to get fastboot on my phone (i think?), the screen on the phone shows the flipped LG logo and at the top right it says 2.0 fastboot (flipped of course)
but, what am i supposed to do here?
i see the 2 omap devices listed on my device manager
whenever i try to run the kdz offline flash tool (if i'm using the right one), it still doesn't detect the phone as connected, doesn't even try, just errors and tells me to connect to usb port and restart or exit
what am i supposed to do once i'm in fastboot recovery for my phone?
should i comment out the 2 listings i added to the hosts file? should i NOT be running shttps app? which kdz offline flash tool should i be using? (currently trying: UpTestEX_mod2_marwin.exe)

You should run start.bat and select flash ICS u-boot/x-loader for P769
When it finish, reboot you phone to S/W update mode and try to use UpTestEX_mod2_marwin.exe to flash your P769 kdz again to restore your phone.
Maybe I miss something about P769 model, please search in FAQ forum many people have this issue, and most of them have fixed it.

you guys are awesome!
finally got my phone back on rooted firmware
now to unlock the bootloader
Okay guys, I think my phone has a soft brick (no boot logos), so I'm trying to do some restoration... but I'm not having much success.
So, I found a solution in XDA (/showthread.php?t=825173&page=3) saying that I should plug my phone in without battery, SD nor chip and disable the "LG Modem" on my Device Manager. Afterwards, start KDZ Updater and configure it to CS_EMERGENCY. Then I should install a 2.1 French firmware and as soon as KDZ finishes I'd plug off my phone, plug it back in and start it in DL mode again, this time flashing a file named "OUT.kdz", which gives back the boot logos.
Problem: KDZ Updater hangs as soon as I press "Start". It simply freezes when it's in CS_EMERGENCY. I have no solution to this whatsoever, and I also have another thread with previous problems I ran into (Soft-Bricked LG GT540 Optimus).
These are the best forums I've found for any kind of phone, so I'm positive I'll get the help I need, even if I might need to wait some time. Kudos to the admins and every member for taking part of such a great community!

I've fixed all my issues! I'll paste what I said in another thread. Yay for one-full-year struggles!
Just wanted to leave my 2 cents here, I've been trying to do my best since around august 2014, no success. 2 days ago I retried this, and I DID IT! I will tell everyone what I did very shortly:
My problem that I solved: I can boot, device works like a charm. But: no boot logos, no recovery.
My solution for TL;DR: UNINSTALL ALL DRIVERS FROM DEVICE MANAGER 1ST, then reinstall. After that, flash a fastboot ROM and use it to WIPE ALL THE DATA IN YOUR PHONE! THIS was what I needed and was never explained: you had to WIPE the old data in order to get the boot screens back.
IN THIS ORDER (THANK YOU to those people from previous replies, gathering all your info was of great value):
Uninstall all of your phone drivers from your PC!!! This is what made most of my headaches go away, just use Device Manager and uninstall anything from LGE. After that, plug in your device in your USB ports (always BACK ports, not front ports, important). It should detect all drivers and download them.
IF it fails (it generally does with LGE USB Modem), you can go to Device Manager > Unknown Device (the one that wasn't recognized) > Right Click and Update > Choose 2nd option, then choose "choose from a list of local controllers" (or whatever the button says). After that, scroll down to LG Electronics, Inc. and install what didn't install.
I also found these drivers, but I did not test them: http://www.mediafire.com/download/p693hcz6kkouh19/USB_Driver_LG_GT540.zip
Huzzah!
Now you're set to begin:
FIRST thing you wanna do is a factory reset, this is something I'd forgotten with time, don't make the same mistake as I did. You can do it by turning your phone on and pressing Volume +/- & Home & Quick Search buttons all together for 5 seconds (it works, be patient and wait for it, even if you open the camera or any other stuff).
Download this Google SDK Tools (unzip and put the folder in C:\ drive) and this Fastboot drivers for GT540 (unzip and put the files inside the folder in C:\android-sdk).
Skip this next line if you know your ROM has fastboot.
Now, if you don't have a ROM with fastboot, I recommend you use either European Open+Fastboot or V20C Orange France Fastboot ROM.
Click to expand...
Click to collapse
Since you have Fastboot enabled, now all you need to do is turn off your device (all this with its battery on it, no weird things) and hold the Camera button before turning it back on. This should take you either to a black screen, or simply to no display, like me. Either one will work anyways.
Now press the Windows key > Type cmd and open it with Right Click > Run as Administrator.
In it, type all this, command by command (you can paste by right clicking):
cd C:\android-sdk
fastboot -w
fastboot erase boot
fastboot erase system
fastboot -w
fastboot reboot
Click to expand...
Click to collapse
And now it's go time! Do what everyone else says in here: Take out your phone's battery, SD and SIM cards, fire KDZ Updater up as Administrator (If your KDZ freezes, then it's either faulty or you did not install msxml, look for a good KDZ that comes with that file and delete your current one), choose CS_Emergency PhoneMode and:
1-Plug your phone while holding the volume DOWN button (don't worry! My phone didn't show "Download Mode" either, if you hear the Windows "Somethingpluggedin" Bump noise, it's ok).
2-Flash French V20A
3-Unplug your phone once KDZ says "==FINISHED==".
4-Plug it once again, holding the volume DOWN button.
5-Flash out.kdz (remember! it's CS_Emergency).

THANK YOU XDA!
This is now DEPRECATED and NOT SUPPORTED ANYMORE since there is an easier method to do it! Links won't get updated! You can still use the written info!
If you want rooted kitkat head to my friend's thread @maxx_hr (THANK YOU FOR ALL YOUR WORK!) HERE: http://forum.xda-developers.com/optimus-l3-l5-l7-l9-ii/development/kk-kk-kdz-p710-root-t2950532
Hello to you all!Warning:
Code:
[COLOR="Red"][SIZE="4"]Your warranty is now void. I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed.
Please do some research if you have any concerns about all contained in this tutorial
before you follow it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.
But since i'm a nice dude i will try to guide you anyway:)[/SIZE][/COLOR]
In this tutorial we will learn how to:
- achieve root on our L7 II (Both single and dual-sim, so P715/P710 and all the derivated phones from them) by LG running a Custom Rom or Stock KK Rom.
FOR THIS FOLLOW ALL STEPS.
- unbrick/flash to a specific firmware using Lg Flash Tool (In this tutorial there are only 2 KDZ files stock JB for P710 and P715. If you want to recover from a brick or want a different KDZ file you can find them over here: http://lg-phone-firmware.com/)
FOR THIS FOLLOW STEP 1 AND STEP 2 (install all drivers including adb and download the files that are needed at Step 2).
- flash with CWM (There are 3 methods I describe. Use the one that suits you the best. You can flash any *.zip that is suitable for your device.)
FOR THIS FOLLOW STEP 5.
Save your data you need, you will lose all data so backup with Titanium Backup or a program you like the info you need.
ALL DOWNLOADS ARE AT THE BOTTOM OF THE POST!
This tutorial will be split in steps as the following:
1. Preparing the Windows machine with the right drivers and software.
2. Reverting back to Jellybean Stock Rom.
3. Rooting on Stock Rom (Jellybean).
4. Installing Unlocked Bootloader and ClockWorkMod Recovery (CWM).
5. Flashing KitKat or a Custom Rom through CWM.
6. Flashing Root through CWM.
So let's start the job.
1. Preparing the Windows machine with the right drivers and software.
Uninstall everything related to LG from Control Panel (Drivers, PC Sync etc).
Restart your PC.
Download and unrar the archive "LG Drivers.rar".
Install both files inside and restart your computer.
Download "adb-setup-1.4.2.exe" and install it (answers should be y y y and install the drivers when prompted).
Download "Framaroot-1.9.1.apk".
Download "LG Flash Tool 2014.rar".
Download "Free LG P710.rar"
Download "P710 Stock KK.zip". -> Stock KK image with Stock KK kernel in it made from the original V20 KDZ (Open Europe).
Download SuperSU
*Download "P715 Stock KK.zip" and "LG P715 (JellyBean).kdz" if you are running a dual-sim version of the phone.
*Download all the files you need!
From now on I will consider you have this files and I will just call their names when to use them.
2. Reverting back to Jellybean Stock Rom.
Open the back cover of your phone and pull the battery out. Wait about 10 seconds. Put the battery back in.
While HOLDING (keep pressed) the VOLUME DOWN BUTTON insert the USB Cable in the phone (you need to have your USB cable inserted in an USB 2 port from the back of your PC).
When you see the yellow screen with emergency mode stop pressing the button.
Unplug the USB from the phone and then plug it in again.
Unrar "LG Flash Tool 2014.rar" and open "LGFlashTool2014.exe" with right-click Run As Admin.
*If you cannot open this program you need to install "VC_RedistInstaller.exe". You are missing some libraries of visual C++*
*IF YOU HAVE ANOTHER PHONE (another LG or P715) DO THE SAME INSTRUCTION AND REPLACE JUST THE KDZ FILE ON "Select KDZ File" TO THE ONE YOU DOWNLOADED AND IS SUITABLE FOR YOUR OWN DEVICE.
Move PhoneMode from DIAG to EMERGENCY. Select KDZ File: you have a file called "V10J_00.kdz" in the same folder as the tool. Select that. Press CSE Flash (CAUTION!!! This will reflash the phone and YOU WILL LOSE ALL YOUR DATA SO BE WARNED).
Another screen will open and press START.
Another screen will open once again press OK.
At a point you will get an error like "Offline BLA BLA". DON'T DO ANYTHING DO NOT PRESS OK.
Wait until your phone reboots and then you can close this tool.
Remove USB cable.
IMPORTANT STEP:
Pull out the battery. Wait 10 seconds put it back. While holding VOLUME DOWN + HOME BUTTON press POWER BUTTON. Wait until you see LG logo and stop pressing POWER. Keep pressing the other 2 until you see android robot doing things. Wait until the phone boots.
CONGRATZ you are on JELLYBEAN (Or the KDZ you chose).
3. Rooting on Stock Rom (Jellybean).
When you see the welcome screen just fast forward everything.
Go to system settings->security->tick Unknown sources->OK.
Go to system settings->developer options->OK->tick USB debugging->YES.
With an SD card reader or with your USB connected as Media Sync (MTP) copy the "Framaroot-1.9.1.apk" to your SD Card.
Using the phone's FILE MANAGER go to external_SD and click the Framaroot you just copied. Run it using Package Installer Just Once and Install.
When finished press OPEN. At the first choice choose Install SuperSU and then press on "Gandalf". You will get Success. Press OK and reboot.
You will see SuperSU in you apps.
YAY! IT'S DONE.
4. Installing Unlocked Bootloader and ClockWorkMod Recovery (CWM).
*SAME FILE YOU NEED FOR LG P715
Earlier you have download "Free LG P710.rar" and in the first step you installed ADB. We will use that now.
Unrar the "Free LG P710.rar" and place the 2 files ON THE ROOT (only on root) of the SD card using device mounted in MTP mode or SD card reader. Put back the card if you use the second option.
WARNING!!!
This can mess up you device so just do what i say step by step!
Plug the USB Cable in the Phone once again and use MTP connection mode.
Click Start+R type CMD and press ENTER.
Run the Following with copy paste to CMD.
Code:
adb devices
You will see your device.
*IF YOU CANNOT MAKE YOUR DEVICE BE RECOGNIZED IN "adb devices" do this:
Install this: https://play.google.com/store/apps/details?id=jackpal.androidterm&hl=ro
Open terminal and continue with the steps down below.
Code:
adb shell
You will see something ending with $.
Code:
su
Unlock the dvice if it is locked and your phone will ask for superuser permission press GRANT.
Code:
dd if=/storage/external_SD/APPSSBL.bin of=/dev/block/mmcblk0p5
This will copy the unlocked bootloader to the bootloader partition.
Code:
dd if=/storage/external_SD/recovery.img of=/dev/block/mmcblk0p17
This will copy the CWM to recovery partition.
Code:
reboot recovery
This will reboot your phone in CWM if you followed all steps correctly.
GREAT SUCCES we have an unlocked bootloader and CWM.
Close your CMD.
Unplug USB.
5. Flashing KitKat or a Custom Rom through CWM.
*IF YOU WANT TO FLASH ANOTHER ZIP FILE OR YOU ARE ON P715 JUST USE THE ARCHIVE YOU NEED AS REFERENCE, NOT "P710 Stock KK.zip". CHOOSE THE FILE THAT IS MOST SUITABLE OR YOU THINK IT'S BEST FOR YOU
I made "P710 Stock KK.zip" you downloaded. This is the stock image for KK Open Europe. Here you can either flash mine or search for a Custom Rom for your device. Either way you will follow the exact same steps but with a different archive. I will take for reference the "P710 Stock KK.zip".
Plug USB in.
You Navigate using Volume Up Button (UP) and Volume Down Button (DOWN). The Power Button is OK.
Do this:
- Go to "wipe data/factory reset" and OK. Go to YES then OK. Wait until done.
- Go to "mounts and storage" and do the following: "format /cache" and "format /system" everytime with YES as second option. Press "go back" once.
- Go to "advance" and then "wipe dalvik cache" and YES. Press "go back".
Here you have 3 options.
OPTION 1.
Use an SD card reader copy the Zip file to the root of the SD card or copying using CWM. Using CWM you navigate with Volume Up and Volume Down to "mounts and storage" press POWER BUTTON (OK). Go to "mount USB storage" and your SD card will appear in windows and you can copy. After that you press "go back" 2 times to get to the main menu.
Go to "Install zip" and then "choose zip from sdcard". Search for the zip file and press OK then go to "YES" and press OK. Wait until done.
Go to "wipe data/factory reset" and OK. Go to YES then OK. Wait until done.
Press "Reboot System Now" and "yes" if asked (if you are asked about some fix or anything after you press reboot now choose the positive thing like the answer that is not no).
OPTION 2.
Copy the file using adb push. Open a CMD window in Windows (Start+R type CMD press ENTER). Copy this:
Code:
adb push
With the space. After space go where you downloaded the zip file highlight it and drag it in the CMD. Leave a space after that and type /sdcard (without space after).
Wait until done and close CMD.
After you copied the file to your sdcard go to "install zip" -> "choose zip from sdcard" -> search for the "P710 Stock KK.zip" press OK then go to "YES" and your installation will beging. Wait until it is done. Go to "wipe data/factory reset" and OK. Go to YES then OK. Wait until done.
Press "Reboot System Now" and "yes" if asked (if you are asked about some fix or anything after you press reboot now choose the positive thing like the answer that is not no).
NOTE: In the zip i made i don't know why i couldn't sideload it but usually you do not have to copy to SD card to flash something. You can sideload it. All you have to do is:
-Go to "install zip" -> "install from sideload"
On your computer open a CMD and copy this :
Code:
adb sideload
Copy with space and after what you copied grab the zip you want to flash and drag it to CMD. Hit ENTER. Sideload will send the zip to phone and process of flashing will start. After it is done reset to factory again.
Press "Reboot System Now" and "yes" if asked (if you are asked about some fix or anything after you press reboot now choose the positive thing like the answer that is not no).
CONGRATZ YOU ARE NOW ON KITKAT. I HONESTLY THINK THAT YOU SHOULD GO FOR THIS CUSTOM ROM OVER HERE BECAUSE IT IS LIKE 10 TIMES BETTER THAN THE STOCK KK. TO INSTALL JUST DOWNLOAD THE ZIP FILE FROM THERE (V2) AND FOLLOW THE TUTORIAL WITH JUST REPLACING THE ZIP WITH THE OTHER ZIP.

6. Flashing Root through CWM.
On some ROMS root will not be there. To avoid this we will flash the SuperSU zip.
To get to recovery you have 2 ways:
- From you ROM connect USB as MTP or in a way that ADB recognizes it (device gets detected by adb devices) type adb reboot recovery.
- Close your phone. At the same time press VOLUME DOWN + HOME BUTTON + POWER BUTTON. When you see the LG logo stop pressing POWER BUTTON. Keep the others 2 until you are in CWM.
Install the SuperSU zip with one of the ways you learnt at step 5.
You are rooted now.
Hope everything worked out fine for you and you are happy. Have a really nice day.

Does P713 have NFC?
This method actually works for dual sim too,you just have to use P715 kdz's.

Yeah it does. Maybe this weekend I will mod it. It is usefull for recoverying from soft bricks also just Step 1 and 2.
it was great till i get stuck on boot loop ,,, now how to solve ?
thanks for the useful guide.
I have a problem though, I cannot go after kdz extraction.
LG Tools stops with an cryptic error like [009.400.120.120.120]PC????? and looking at the log it seems there are troubles in unpacking the kdz file.
I have tried with different roms but still the same.
Does anyone has the same problem ?

I can't really understand you. The point of this guide is to get root on kitkat so flashing with lg flashtool will not work if you want kit kat rooted. I tested that V10J on my own l7 2 (p710). Also if you flashed Jellybean did you press CSE Flash not Normal Flash?

Ok do that step again. Flash with that tool using the image i provided. After the last ok. Even when you get the offline error don't touch it until phone reboots. If you get bootloop do this.
1. Pull out battery. Wait 10 seconds. Push battery back in.
2. While holding POWER DOWN + HOME BUTTON press POWER BUTTON. Wait until you see LG logo then stop presing POWER. You will get to see android guy doing stuff. Then tell me if it's ok.

Ok do that step again. Flash with that tool using the image i provided. After the last ok. Even when you get the offline error don't touch it until phone reboots. If you get bootloop do this.
1. Pull out battery. Wait 10 seconds. Push battery back in.

Don't forget to press the thx button it's in the right . I will add this to the tutorial I didn't need it but who knows.
I managed to do the "root" step, but somehow cannot proceed with the next step.
When I check "USB debugging", the phone doesn't connect to the computer for some reason. I tried multiple computers, with no luck. The "adb devices" says just empty "List of devices attached".
If I disable the USB debugging, the phone gets connected just fine, if I enable it again, it gets stuck on "Connected as installer", and doesn't connect as MTP....
Any idea how to fix this?
Do you have drivers installed? Also when you press MTP cancel if your phone wants to install anything.

I tried everything, without luck. I ended just using terminal emulator to copy the files on phone directly (might be cool to add this to your tutorial, as someone else can also have this problem). So, now I'm on Amigas ROM - makes a HUGE difference! Thanks, looking forward for some other custom ROMs for this phone..

Strange huuummm. I don't know. Yeah i will add Terminal Emulator also in weekend. Never happened to any of my phones before... Maybe driver conflict on your PC or something like that.
