virus in the micro sd..advice format/flash

may be it could be affect by virus and OS files maybe deleted. So try it.. when the mobile is switched of press caller button(green) * button and 3 button at a time and switch on power button. do not leave till the three buttons till process is completed. (do not forgot to charge your battery before u do this, or connect to charger)
if the problem is not solved take it to any Nokia Mobile store to get repair ThanQ

Would you mine formatting ? if not, while the phone is off, press call ( the green one) + 3 + * and turn the phone on.

Yes, you have to press 4 buttons at a time. *,3,call and the power on.

Try it. it should solve your problem.

You may miss 3/4 times...cz, it is not so easy to press all at a time correctly.

Try this:
Take your SIM card out.
Make sure your phone battery is fully charged.
Press * 3 send at the same time and turn the phone on. Keep them pressed until the reset screen appears.
Give it time to reset.
Yes! I know. You need someone to press the ON button.

Baby-dribble + Phone = Dead Phone If your phone was exposed to baby-dribble, your kid might have killed your Phone. Take it to your local Service-Center and have them take a look at it. Let them decide if the phone could be repaired or might be up for early replacement. Normal warranty-conditions might not cover the damage if its "moisture-damage".
