I need to restore the factory settings,it requires

HI,

The sefault security code would be 12345

You have to type in security code of your phone in order to reset the phone....
By default the security code is 12345 and if you have changed it, you must be knowing....
BUT IF YOU WERE NOT ABLE TO GET INTO THE MOBILE WITH THE 12345 OR IF YOU FORGET THE SECURITYCODE, the one and the only way is to flash the mobile phone(ie, reinstalling the firmware), this cant be done by the normal person, u have to take the phone to nearest service center and flash it, they may charge u very minimal amount......
After that you may get the factory default seurity code

CAUTION: You may loose all the content stored in the phone memory, be careful,but no other way than doing this
