1. Download KDZ Updater and LG united mobile drivers from here.

2. Extract the rar file and install LG United mobile drivers.

3. Disable all LGE modems under modems from windows device manager.

4. Charge your phone since we cant really tell how much juice is left in the battery even though the screen is on.

5. Download the stock firmware (also known as rom) from Lg
