[LG Optimus L3 II, L5 II, L7 II, L9 II] neutrondev:
Hello to you all I am making this flashing tutorial since I have seen enough people asking how to flash using this tool.

This tutorial will be 100% detalied and noob friendly, with pictures. So fasten your seatbelt and let's go.

1. Disclaimer:

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:)

2. General info:

This can be used to flash a new firmware that you will download from LG firmware website. You can upgrade/downgrade your current version.

This can be used for every situation that can get you in a working Emergency mode/Download mode.

This will work/not work (I didn't test) on versions grater than Windows 7 both 32 and 64 bit. I am not going to give support to Windows 8/Windows 8.1. If it works for you it's nice. If not I will ignore the posts like "What can I do not working on Windows 8" and so on. Same thing goes for WINE (windows loader for LINUX). Use this with Windows XP or 7.

3. What we need and getting ready:

a. Firstly, we need the Drivers for our Phone. The drivers I am attaching must be universal for LG but if they do not work for you then you need to search the drivers the manufacture made for your device.

Universal Driver for LG (TRY THIS FIRST BEFORE YOU GO AND DOWNLOAD FROM LG WEBSITE): LG Drivers.

Install the driver (the one I provided first). If your phone is not detected then search on LG website.

*If the ones I provided don't work you can fine the ones for your phone here: http://www.lg.com/. Search in the right up corner the model of your device. Select it. At download section (in the right of the mini-phone picture) you will see Software Updates & drivers. Select that and download the USB Drivers for Windows.

b. Secondly, we need the KDZ image that you want to flash. I am not going to provide any; you will download the one that you want FOR YOUR DEVICE (do not use any KDZ not intended for your device) from here: http://lg-phone-firmware.com/.

Press on the phone you have and download the image you want.

c. In the third place you want to download the tool: LG Flash Tool 2014.

*You need Winrar or 7Zip or any unraring program. Unrar it.

4. The actual flashing:

A)YOUR PHONE SHOULD BE IN EMERGENCY/DOWNLOAD MODE. The keys to do this are different from device to device so search the forums for your key combination. I will provide the way to get in Emergency for the L7 II and maybe L5 II and L3 II. Think this is the same for the first gen devices but can't confirm.

*With the phone turned off (I suggest to pull out battery for 5 seconds then put it back to be sure) hold Volume Down button and plug the USB cable that you have in your PC. If this doesn't work try holding Volume Down + Volume Up and plug the USB. If this doesn't work search the forums. You might also have a hard bricked device and this method won't work then.

B)Place the KDZ file you downloaded the 3.b. in the same folder that you unrared at 3.c. and Run as Administrator. (BE SURE TO HAVE THE KDZ FILE IN THE SAME FOLDER AS THE TOOL. The file i took for example is "Stock JB ROM.kdz").

*If you can't open this program then you need to instal this: C++ Libraries.

C)This will appear. Leave all the way it is and press the little folder in the right.

D)Select the KDZ you placed at point 4.B. and press Open (DO NOT SELECT RA or RC KDZ).

E)After you pressed Open you are back to the main screen you saw at point 4.C. Good.

Press Normal Flash (the left option) if you want to flash new KDZ preserving data (no data will be deleted). I do not suggest this because you might get a bootloop and you need to hard-reset (will wipe data). Always have all data backed-up.

Press CSE Flash (recommended) if you want to flash new KDZ with full wipe of data.

After selecting what you want you will get this screen.

Press START.

D)After you pressed START you will get this. DO NOT CHANGE ANYTHING, press OK.

E)Another dialog will pop and will flash your phone. First it will check USB connection but you already have USB connected when you got in Emergency so you should be fine. I assume you checked drivers at the Driver step so I assume there will be no problems.

IMPORTANT: DO NOT EVER DISCONNECT THE DEVICE EVEN IF YOU THINK IT'S STUCK, THE WINDOW GOT BLOCKED, IT DOESN'T SHOW ANYTHING OR ANYTHING ELSE. YOU CAN DESTROY YOUR DEVICE DO NOT UNPLUG AFTER YOU PRESSED OK AT STEP 4.D. WHEN THE DEVICE REBOOTS LEAVE THE USB IN FOR 2 MORE MINUTES THEN YOU CAN UNPLUG.

F)In some cases you might get a bootloop after 4.E. is completed. All you have to do is hard reset your device. Search the forum for specific hard-reset procedure. In P710 it's like this: with powered off device hold Volume Down + Home button and press Power. When you see LG logo stop holding Power. Keep other 2 buttons until you see android guy.

That's all folks and now the credits:
