No light on lcd - Nokia C3 Cell Phone

Hi,
If your Nokia C3 meet a permanent problem, you should reset your phone. There are two ways to perform a reset on the device, the hard set and soft reset.
1 how to perform hard reset on Nokia C3
To perform a hard reset on the C3, press *#7370# and press Dial. The phone will request the security code that is 12345 by default. Since the hard reset will erase all date in your phone, you should backup important data before performing a hard reset.
2 how to perform a soft reset on Nokia C3
If you want to soft reset your Nokia C3, you need to press *#7780# and then Dial. The default security code is 12345. When you do this, your phone will come back to original factory status, but you will not loose personal data. It is better to make a backup before performing any kind of reset.

Hope this helps.

Thanks.
