[Nokia Lumia 620] Sad smiley on start screen :-( , cant even hard reset

Hi after I bought my phone, I did not turn on Speech feature for first few months, then I wanted to give it a shot and downloaded the necessary upgrades and installed. It gives me a message that the phone need to be restarted and the phone automatically restarted but after that the phone wont start. At the start screeb after the 'NOKIA' logo and two wheels there's a sad smiley :-( and the phone remains in that state. I cant even turn it off using power button. I have to manually remove the battery every time I want to shut it down (frustrated!!) After trying soft reset for a few days, I decided to hard reset the phone. But I cant even perform hard reset. From some post I came to know - I need to press my volume down, power & camera button simultaneously, and when the phone restarts press the volume down & camera button only. Tried several times. But in vain.  I additionally tried resetting the phone with microsoft suggested way of turning off the phone (in my case removing battery and putting it back) then turn on, hold the volume down but exclamation mark does not come for my case, it keeps on restarting with NOKIA logo only, still I tried Volume Up, Volume Down, Power, Volume Down (as suggested by microsoft) but no use.

Can anyone help me with this problem, at least any hard reset method?

Here is a picture of the start screen
