Here is how to flash Nokia devices (Java and Symbian Only) using phoenix and USB cable. 

REQUIREMENTS

1.  Infinity Box  
   
2.  Nokia PC Suite  
   
3.  Firmware files for flashing 
   
4.  A GOOD USB cable
   
5.  Well charged battery
   

WARNING / NOTE

• While flashing, the process shouldn't be interrupted due to insufficient charge on the battery or due to disconnection of the USB cord as it may result to a totally damaged phone.
  
• Always try to search well for the latest firmware before download / flashing. Using a firmware below the current firmware on the phone would result in a partially bricked phone (this is because downgrading isn't allowed)
