Hi, fellow Optimus owner,
Idk much about the unbricking process myself - I am not a developer, and I've tried to carefully follow the advice offered on the stickies here in the forums. That's kept me out of most problems. But Im pretty sure in your situation, you will need to download the Android SDK, the PC drivers for the LG Optimus V (for your OS), and then connect to your phone via USB cable and ADB (Android Debugging Bridge). Then you will have to run a set of commands to push the recovery to your phone.
A few threads on the LG OV forums can fill in the details. Good luck.
