 METHOD ii

⦁ LG Drivers Installed.
⦁ LGMobile Update Tool installed.

Notice: Latest Version of LG Mobile Update prevents updating firmware from kdz files, if the phone is not in the firmware level LG expects. LG Is watching everything when you run firmware update with KDZ Method, logging everything, your mobile No, SN No, OLD Firmware, New Firmware etc. To bypass this first we make our PC to serve LG update tool locally (offline). More Info here. Then we follow the steps below as before.
To make things easier, run the Automatic Offline Procedure.vbs script, it adds 127.0.0.1 csmg.lgmobile.com entry (temporarily) in hosts file, sets a small HTTP Server on the PC listening to port 9002 which serves the requests of the LG flash utility, installs MSXML, runs all the utilities automatically and finally reverts back your hosts file removing the above entry. This script must be run as administrator so Start  –All Programs  Accessories   right-click on Command Prompt  select Run as administrator. Then drag-drop the script in and press enter.
If you are running the “Automatic Offline Procedure.vbs” continue from step 5.
