Latest Version of LG Mobile Update prevents uses from updating firmware from kdz files.

As LG Tools relay on lg webserver to provide application updates and firmware updates it's not possible to just use the old version as it force fully update it self.

I used network sniffer(Wireshark) to sniff all the traffic between application and LG Webserver i tracked the important urls and the data coming from LG Webserver. I created all the files with same names and with data from LG Webserver. I changes the LG Mobile Application from to Rest of the files has same data as LG.

How To:

1) Download

2) Install

3) Go to Settings

4) Go to HTTP Settings

5) Change Port to 9002

6) Extract the Content of Attached Zip file into C:\shttps\www

7) Edit C:\windows\system32\drivers\etc\host in notepad and add the following Line

8) Enjoy Flashing firmware as usual

This method has lot of advantage
-LG Is watching everything when you run firmware update with KDZ Method lg is logging everything you mobile No, SN No, OLD Firmware, New Firmware etc..

If you have any questions or need any info feel free to ask i will try my best to help.

This is pretty awesome. I had exactly that problem when I tried do downgrade to FroYo because of the Gingerbread Baseband issues.

That wonderfull moment community finds an flawless solution to bypass permanently the control of a company on OUR phones that we paid them the big price for.


For the time you used and for your generosity sharing it

Sorry for the stupid reply... I had already flashed my phone with v21v using the kdz method, am I to understand this is not possible anymore because newer versions are available? And this allows us to flash the older versions again? so in theory I could try v20b and go back to v21a or v10 or whatever I wanted...?
