Always remember to backup your phone before performing resets as your data may be lost.
First try these
*#7780# - Restore factory settings - resets all the settings to the default
*#7370# - Reformat your phone
If the above two don't work then try these.
Firstly take the battery out for 5 minutes and then replace and see if that makes any difference.
Then try the "3 finger deep reset" which is depress these three keys simultaneously "*" "3" "green phone" and then power on phone whilst keeping those same three keys depressed until you hear start-up tone.
This should ONLY be done if the device doesn't power up normally anymore and it wipes everything in the Phone memory that is not part of the ROM.
