    I think its hold home and volume down, press power to turn it on. keep holding the other 2 until recovery menu appears.

    Make sure you install Custom Recovery first. The phone doesn't come pre-installed with any kind of recovery menu. Some people end up wiping their phones not realizing they have to install it first.

    Both files should be on the root of your SD Card. Did you run the # cat /sdcard/flash_image > /system/bin/flash_image command first?

    It sounds like you are missing a chmod command that will change the permissions on the file before it's installed.
    chmod 755 /system/bin/flash_image

    Hate to do this but, could you start over and follow the steps in this tutorial?

    Here ya go.
    Android SDK | Android Developers
    Grab the zip version and extract the contents onto your C: drive.
    It should look like this when you are done.
    C:\android-sdk-windows
    Then create a shortcut to the program SDK Manager.exe onto your desktop for easier access.

    After you double click on sdkmanager.exe a window will open and give you the option to download LOTS of tools.You only need:
    Android SDK Tools &
    Android SDK Platform tools.

    If you haven't done so, you also need to download the drivers for your phone and install them before connecting your phone.
    http://www.lg.com/us/support/mc-support/drivers/LGMS690.zip
    As for using adb to install recovery.
    Make sure USB debugging is activated (On your phone go to settings>applications>development and check USB debugging)
    Now plug it in but DO NOT turn on USB Storage.
    Then open up a command prompt on you computer and type the following: cd C:\android-sdk-windows\platform-tools.
    NOW you'll be able to input the commands in the recovery thread.

    Don't put the .zip on the SD card. You extract flash_image and put that file on the SD card.

    Yup I am one of those. and if your using the emulator. MAKE SURE you see that some of the code is commas not periods. It took me forever to figure that one out lol.
