How to flash baseband without flashing kdz?

Flash using this method: http://forum.xda-developers.com/showthread.php?t=1244490
Use other files only: http://artas182x.tk/LGFlashTool+CRACKED.zip
You need only to select fls file (in guide author select directory). You will get error, but baseband will be flashed.
You need standard usb cable for L9.
