1. Download the .exe file from here (MediaFire) or here (MultiUpload)
2. Put the phone in fastboot mode by holding down the camera button all the way and powering on the phone. Make sure you hold the power button while the LG logo is shown on the screen. A blank screen will then appear after a few seconds. The phone is now in fastboot mode.
3. Connect the phone to your computer by the USB cable.
4. Run the .exe program and let it install CyanogenMod 7 on your phone :)

Read a bit further up, you need to install fastboot on your phone using these steps:

To install this ROM you need to have fastboot enabled on your phone. If you have Android 1.6/2.1 installed from LG, then fastboot is not enabled, if you have Android 2.2/CyanogenMod6 installed from my previous post then you have fastboot enabled so put your phone in fastboot mode (hold Camera on power up) when needed. I will explain how to enable fastboot on your phone (this involves re-flashing/replacing your currently installed firmware):

KDZ Updater CarphoneWarehouse Unlocked.zip - A link to a zip archive with all the files needed to flash Android version 2.1 with fastboot (Carphone Warehouse Unlocked)

KDZ Updater Europe Open.zip - A link to a zip archive with all the files needed to flash Android version 2.1 with fastboot (Europe Open)

Download either version, it doesn’t make a difference, you’re going to be replacing 2.1 with 2.3 anyway ;)

Now, how to flash these versions; I'll explain in detail how to flash the ROM's from starting with backing up.

1. Before you start, make sure you backup all your data (If you do not wish to backup your data this step is not necessary) by installing the z4root.1.3.0.apk file onto your phone, then open it and choose 'Permanent Root'. Your phone will root and reboot. Then go to the Market and install 'MyBackup Root', open it and do a backup of your apps and personal data (contacts, sms, call log etc.) Once this is done, go to Settings>SD Card and Phone Storage>Unmount SD Card, a notification in the notification bar should appear saying 'SD Card safe to remove'. Remove the battery cover and remove the SD card and store it in a safe place. Then continue to step 2.

2. Extract the .zip file you downloaded to your computer (e.g. your desktop). Open the folder and install MSXML 4.0 SP3 Parser (msxml.msi).

3. Once that has finished, install LGAndroidDriver_WHQL_ML_Ver1.0_All_Win7.exe which are the drivers so your computer will recognize your phone. Windows XP Users download this driver, extract the contents anywhere (e.g. desktop), right-click on the 'android_usb.inf' file and click 'Install'.

4. Next, open KDZ_FW_UPD.exe
(i) Change 'Type' to '3GQCT' *THIS IS A MUST, THE UPDATE WILL NOT WORK OTHERWISE AND YOU MAY BRICK YOUR PHONE*
(ii) Make sure 'PhoneMode' is set to 'DIAG'
(iii) Browse for the 'V20B_00+Fastboot.kdz' file.

5. Prepare the phone by enabling USB Debugging by going to Settings>Applications>Development>Enable USB Debugging and connect the phone to the computer via USB cable and wait for the drivers to install for the phone. Sometimes the computer still won't recognize the phone, if this is the case, try this: Windows Vista and 7 users press start and type device manager (Windows XP users right click 'My Computer' and click properties, then click the Hardware tab and click Device Manager) then locate LGE Android Platform Modem, right click it and click disable. Accept any warnings that come up. Also, make sure you've disabled Mass Storage Mode on your phone. To do this, go to Settings>Storage>Enable Mass Storage, and untick the box.

6. Click 'Launch software update' and do not use your computer until the update is complete. The update will take roughly 10-20 mins to complete.

And to your question in the op asking if its safe, the instructions are perfect, also the files are fine, but reflashing is never safe, there is always the possibility your PC could crash or somthing during the update which could brick the phone.
