Step 1 Perform a soft format of your phone by dialing *#7370# just as you would any other phone number. This will erase the contents of the phone's internal drive.
Step 2 Use a hard format only if absolutely necessary; this sequence will reset your phone back to its original factory settings.
Step 3 Turn your phone off.
Step 4 Hold down the green answer, * and 3 buttons.
Step 5 Switch the phone on without releasing the buttons.
Step 6 Release the buttons when "aFormattinga" appears on the screen
