7) You have all needed information about your firmware. If you have older firmware, just replace some letters in FW link.

csmg.lgmobile.com:9002/swdata/WEBSW/LGP500/ASEABK/V10c_00/V10C_00.kdzSniffing of communication of LG Update client

If above not working as you expected, you can take a look on communication between client-server.

1) Download and install membrane-monitor (http://www.membrane-soa.org/soap-monitor/)

2) Configure it as proxy (LG client gets configuration from your default browser, so just set your browser to connect through membrane-monitor)

3) Turn on filter on lg server (create rule for filtering *lgmobile.com*)

4) Start client

5) Watch messages between client and server. If your LG client works fine, you can get download link for your latest firmware.

after downloading the correct stock rom for ur phone.....use kdz updater to update phone

Using KDZ updater:

You can download kdz updater from here

http://xdaforums.com/atta...5&d=1287222698

Download KDZ updater and uncompress it

Install msxml.msi from the uncompressed directory

Note: put your phone in emergency mode, otherwise it will not detected by your pc

[IMPORTANT] Disable 'LGE Virtual Modem' in PC's Device Manager. (In your Windows operating system, go to Control Panel > System > Hardware > Device Manager > Modems > Right click on LGE Virtual Modem and click Disable.)

now run kdz_fw_update.exe

Chose TYPE as 3GQCT & Phone Mode as DIAG.

select your downloaded stock rom(*.kdz)

now lanuch update process

If all goes well, in 5-10 minutes the phone will be flashed with the new firmware.

Wait till phone reboots by itself ( which it might not) so wait for a while before manually switching it on(I waited 2-3 minutes).

Now in my case...after booting i thought again my pc stuck on lg logo so wait for a minute or two....then you will see android logo....

but again in my case....after boot my phone shows Android logo with an exclamation mark....

Now manually reboot the phone...and this time it will work fine and you will get you home screen....

This whole process worked for me. Hope it also works for you.
