On short circuiting the jumper the communicator changed to boot loader mode . but still i am not able perform factory restore operation.
Can you provide more details about why you are factory resetting the device?
To help me understand the current status of the device what are the LED’s on the device doing?
Were you able to connect to the device though configuration manager?
Thankyou for your suggestions.
