First of all the method of Hard Reset is very simple and easy to understand all you need is to turn off your Andriod smart phone and press and hold the Volume Up and the Volume Down keys both at the same time, and after that press and hold the Power key until a test screen that shows some available options appears. Press the Volume Down key to navigate down through the options until it highlights Factory RESET then press the Power key to select it.
Thats it all the data on your Andriod phone would be wiped off and phone would become like seal pack.
