Your phone is OFF.
Remove the battery.
Connect the phone via USB-datacable to your
pc.

flashing process. If this is the first time you are doing it, you should be
asked to install a driver. The missing driver is located in the

folder. After the driver is installed, you may have to start the flashing
process again.
