yes that's right . we have to press the power button first and then press the +volume button 2-3 times so that if the phone don't catch the button it will catch by pressing +volume button 2-3 times while starting.If you don't have the volume button then you will get in market .Give your phone to a trusted mobile repair man he will put up a new button of volume. Thanks Stephan Prastman for giving me a advice to reset my data that you have told Thankyou Very much.....
