Today (24 Sept) I got a prompt on my iPhone 4S for updating iOS to iOS7.x. I did the update which proceeded very well. However, after that the iPhone has stopped working.

On pressing HOME Button it shows a Black Screen with APPLE LOGO in Center and 5 dots & VodafoneIN on top leaft, a Watch Logo and 100% (Battery Charge) on right left.

Pressing HOME Button has no effect.

Earlier I had Selected SOFT HOME BUTTON which is shown on Top of Screen After pressing HOME Button when SOFT HOME Button is touched, 4 icons "Siri" "Device", "Home" & "Favourite appear and in center there is a faint glow which behaves as a Soft HOME Button.

Touching DEVICE shows 6 Logos "Volume UP", "Volume Down", "More (3 dots)", "Mute", "Rotate Screen".

Touching Favourite shows a "Pinch Logo" seven Blank Squares (drawn with dashed lines".

Touchiing HOME has no effect.

Touching "SIRI" closes all and goes back to Blank Black Scree with APPLE LOGO in Center and and 5 dots & VodafoneIN on top leaft, a Watch Logo and 100% (Battery Charge) on right left.

I tried putting Power ON and Off several times but to no effect.

I tried to call my iPhone from another mobile as well as landline. I get a Ring Back but nothing happens on my iPhone.

Please guide me about how to restore my iPhone.
