How to establish Kies connection:

1 Disconnect the device and data cable from your computer, then reconnect again
2 If you are connecting the USB cable to a USB hub, try connecting the cable directly to your computer
3 Close Kies and reopen the application
4 Reboot your computer and your device

If you are still having trouble with the connection:


If the connection error continues, try the following:

• Remove SD Card - turn off the mobile device completely. Remove the SD card and then try connecting the mobile device to the PC using Kies again.

• Check for defective USB Cable - The problem could be due to faulty USB Cable or USB port of the PC. Try to connect the USB Cable to a different USB port. If it does not work, connect other devices to see if the PC can detect it using the same USB cable.

• Run Troubleshoot connection error on Kies to fix the problem. The entire process includes reinstalling the driver and fix any errors found. For Kies 3, go to Tool > Reinstall device driver > click Reinstall. Once the process is completed, reconnect your Samsung mobile device.


Mac® : If you are using a Mac®, click Tools > Install driver to install the necessary drivers or your Samsung device.
