How To Flash With KDZ

1. Download KDZ updater and uncompress it

http://www.4shared.com/file/UleS4dP3/

KDZ_FW_UPD_EN.html

2. Install msxml.msi from the uncompressed

directory

3. Charge your battery to almost full state (I'm

not sure, but it can be reason if phone

doesn't start)

4. Turn phone off somehow (remove battery

etc.)

5. Install drivers properly

Get rid of all usb drivers like Nokia,

microsoft visual ++ run time environments

Install the LG drivers by selecting the update

manager from the lg site

Disable LGE Virtual Modem. In your Windows

operating system, go to Control Panel >

System > Hardware > Device Manager >

Modems > Right click on LGE Virtual Modem

and click Disable.

6. Enter emergency mode and connect ur device with USB cable to PC.

7. Yellow screen with text emergency mode

should appeared

8.Btw use good quality stock usb cable.

9.run KDZ_FW_UPD.exe (Has administrator).

Select Type : 3GQCT (I have one report that

CDMA mod works too )

Select PhoneMode : DIAG (in case of fail try

EMERGENCY, and as last chance use

CS_EMERGENCY)

10. I Recommend do not switch phone off. There

was some people, which done it and after

they were not be able to turn it on again. If

flashing failed, just select some another

mode and try it again, again, try shake/

connect disconnect, again, again....

11. In KDZ file : Choose the ROM file you

downloaded in the first step

12. Press Launch software update

13. If it fails , try again and again and again till you get success !

14. Make sure that all update was done

successfully. Phone should restart itself

automatically

15. Disconnect the USB cable from the phone

16. Press the three button combo for HW reset

of device i.e volume up + home + power

button

U r done !!!

If you get success , add [SOLVED] as prefix to this thread name.
