Step-7: Connect the Galaxy Ace to the computer using USB cable while it is in the Download Mode. Wait for some time until Odin detects the device. When the phone is connected an Added message will appear at the bottom left of Odin message box. Also, the ID: COM box in Odin will turn yellow with the COM port number indicating successful connection
