Within 10 seconds, need to hold down three buttons simultaneously:

1 - click on the "Inclusions"

2 - the main screen (or the menu button on the phone)

3 - volume knob (press the volume down rocker "down").

But note: all the settings of your phone will be reset to the factory, and all third-party programs will be removed permanently. To resort to hard-reset, I suggest, in extreme cases.
