If you are trying to root and install CWM, use the all in one from PlayfulGod's thread here (if its for V6) since its the latest CWM -

Here is my routine steps:
on PC
- install latest LG drivers
on Phone
- make sure debugging is enabled
- allow unsigned code
- set usb to internet mode as modem
on PC
- extract rooting files to a folder with no space in the path ("c:\SpectrumRoot" vs "c:\Spectrum Root")
- when I connect the phone, make sure it shows up in device manager as an ADB device
if all that checks out, run the bat file.
You might wait a few minutes before doing this just to make sure a dev doesn't step in here and say I'm an idiot for recommending these things (in a nice way of course

) but I know this works since its what I do... my 2 cents
