Default [UNBRICK][ROOT] FLASH Any LG Factory ROM (kdz) WITH OFFLINE FIX

[GUIDE] [UNBRICK][ROOT] FLASH Any LG Factory ROM (kdz) WITH OFFLINE FIX
Thanks to all developers and contributors: [Only Registered Users Can See Links. Click Here To Register...] , [Only Registered Users Can See Links. Click Here To Register...], [Only Registered Users Can See Links. Click Here To Register...] I thank to all the users of this thread who gave feedback and reported issues time to time, which helped "us" to make this guide better and perfect.

First thing first, this is not my original work, I have just tried to consolidate all the scattered things together for SAFE and EASY flashing and rooting of L9 variants. Written this guide as many pals were having issues with OFFLINE KDZ FLASHING and help was scattered in many pages creating more confusion.
Wow! After so much of followup with xda mods, finally we got Home (Sub-Forum) for LG L9 series.

  1. PLEASE, USE INFO AT YOUR OWN RISK & INTELLIGENCE.:cowboy:
  2. Flashing KDZ removes Root and CWM, so you will need to root again.
  3. Flashing KDZ does not wipe your data, but if you get bootloops you need to hard-reset it, so please backup data first.

LG Update Tool works on all versions of windows (xp/w7/w8-32/64bit) for flashing any version of Android (GB/ICS/JB). If it does not work on your windows, something is missing on your system and if anyone here cannot help you then, you have find your own ways. Don't expect Spoon-feeding for everything.

DEVICES FLASHED WITH THIS GUIDE AND TESTED OK: LG Optimus 2x (P990) and LG Optimus L9 (P76?)

This thread contains two "MAIN" separate parts.


-------------------------------------

[GUIDE] FLASH L9 Factory ICS/JB ROM WITH OFFLINE FIX + UNBRICK
Works perfect on Win-XP/W7/W8 32bit/64bit. UNBRICKS ALL SOFT-BRICKED L9 (P760/765/P768/P769)

TRUST ME THIS IS NOT LENGTHY PROCESS, I JUST HAVE PUT THEM IN EASY STEPS FOR COMPLETE NOOB PERSON. EXPERTS PLEASE STAY AWAY FROM COMMENTING HARSH ON ME.

THIS METHOD IS ALWAYS FASTER THAN ONLINE WITH PC SUITE, WHICH DOWNLOADS HUGE FILE ONLINE AND YOU NEED TO WAIT UNTIL IT FINISHES DOWNLOADING IN THE MIDDLE OF FLASHING.

In first part of this Guide, we are creating a Local Web-Server for LG Support Tool and will try everything which will PREVENT the tool to connect to real LG server over internet. We have to create SMALL SERVER on our own system and redirect tool to this webpage.

FIRST DOWNLOAD YOUR OWN OFFICIAL KDZ (LG ROM) FILE FROM MY [Only Registered Users Can See Links. Click Here To Register...] or from anywhere and proceed...

0) Precautions:
___A) Select "Debugging Mode" as ON (Ticked) in Phone Settings (Developer Section)
___B) Select "Install from Unknown Sources" as ON (Ticked) in Phone Settings (Security Section)
___C) Indian version of L9 does not come with "Lookout Security Antivirus" already installed. But KDZ from other countries may have it already installed, FORCE CLOSE AND UNINSTALL it from app manager. If you cannot uninstall, at least DISABLE it. This program is known to be preventing connection and rooting of device.
___D) Remove all other USB devices (external hdd, backup drives, other phones, etc) and cables connected to PC to avoid issued due to voltage loss. ([Only Registered Users Can See Links. Click Here To Register...])
___E) OFFLINE KDZ FLASHING DOES NOT LOOSE PHONE DATA, BUT YOU MUST BACKUP YOUR PHONE IN ANY CASE.

1) Find NOTEPAD program from StartMenu of Windows and Right Click on it and run it with "Run as Administrator" option. Remember use "Run as Administrator" while opening, otherwise you will not be able to save it after changes.

Now you need to open "HOSTS" file located in folder "C:\Windows\System32\drivers\etc\" with following method.

Click File Menu >>> Open File >>> Now copy-paste following in "Open File" Box.

Please note the opened file name is only "hosts" and does not have file-extension like txt or anything.

When file is opened, add following lines at bottom of "hosts" file, a file with no extension like txt/doc/xls.

Now SAVE file and Close it.


Content of Hosts file looks [Only Registered Users Can See Links. Click Here To Register...]. Close this file , because we may not need it after this point.
AND RESTART PC NOW (check if lines are still there after Restart. They should be there.)


2) INSTALLING SMALL SERVER: Download "shttps.zip" (attached below) and Extract the Zipped folder "shttps" in root of C-drive of your computer.
Now Right click on "C:\shttps\http.exe" file and "Run As Administrator" and in Windows Compatibility Mode with "WindowsXP SP3" (must for Win7/8) , a server status window will open "MINIMIZE IT BUT DONT CLOSE IT" and you will also see a SMALL SERVER icon in TASKBAR, like mentioned below.




WEBSERVER TESTING: If webserver is running correct, YOU SHOULD SEE A SWEET GIRL WITH L9 WHEN YOU CLICK THIS >>> [Only Registered Users Can See Links. Click Here To Register...]
If you don't see a GIRL, something is wrong. Start again.


COMING TO ACTUAL FLASH PROCESS.

3) Download (attached) and Extract "[Only Registered Users Can See Links. Click Here To Register...]" and save the folder on desktop or any suitable place on your hard-disk.

4) Optional if "MSXML 4.0 SP3 Parser" is already installed before: Install it by finding and installing "msxml.msi" file in flash folder.
