My Friend has entered invalid pin number continuously and the handset got locked. Do someone have any idea how can i help him. ????????????

HI WHAT CODES DID HE PUT?? AND IN WHICH MENU?? LET ME KNOW... I think he's referring to entering wrong recharge pin number (or maybe wrong gsk pin). In case of entering wrong pin 10 times, the network does not allow any further operation from that phone. He has entered the handset lock code
