Press and hold the following keys at the same time: Volume Down Key + Power/Lock Key on the back of the phone. Release the Power/Lock Key only when the LG logo is displayed, then immediately press and hold the Power/Lock Key again. Release all keys when the Factory hard reset screen is displayed.
Press and hold the power button for 5 to 7 seconds. This will do a factory reset on unit. The unit will turn off, then back on. Hopefully this will help. That unit does not have the small hole in front to eject disks like a computer unit does.
