ngambil dari tetangga… cara hard reset…
1. Turn off the LG KS-20 completely (do this by pressing and holding the power button and wait for the prompt).
2. Press and hold these three buttons–volume down, Call and power–till the LED (this is beside the front camera) flashes.
3. Release the buttons. That same LED should flash blue/red/green and power up.
4. The KS20 should be in a clean state.
