??? Why are you giving 5V to pin 4?
Usually you should follow this procedure:
1) Start flash magic
2) Reset the board or switch power off then to on again.
3) Download the HEX file.
Have you read the flash magic manual?
Yes i have and i did what u said also ...... even all possibilities
wen i give 5V to PIN 4
meaningless statement
DO NOT use pin numbers, they do nmot maen the same for different packages.

As Erik said above, please either tell us EXACTLY the package, or, better, refer to the pin's NAME rather than number.
You should perhaps read Andy Ayre's very extensive troubleshooting guide: http://forum.flashmagictool.com/index.php?topic=3273.0 , and also the 'V51Rx2 - specific remarks: http://forum.flashmagictool.com/index.php?topic=3232.0
