Headset profile problem in micromax Q5

Hi

I'm facing a big problem that i can not change my HEADSET profile though i remove my headphone.Also i can never pic a call without Headphone or On Loudspeaker.
plz anybody suggest.....

Even i worked out this suggestion from Chetna

( Please again connect your headset device with the fone and call on your number then while your phone is ringing, in between it is ringing remove your headset and then receive the call. Your problem will be sorted out.. I have done it personally & my problem resolved, hope it'll resolved your too.... )

Kindly help me out
