Last Update date : 2014.09.30

Restore Android™ OS from Kies 3


Kies 3 can help you restore the Samsung Android operating system (OS), sometimes referred to as your device's firmware, to your device. If your device fails during an update and cannot be recovered using emergency firmware recovery, or if you have installed a custom version of the Android OS on your device, you can reload the latest version of the Android OS to your device.

NOTE: This feature is not available for all devices. When you select the option, Kies 3 will verify the availability for your device. If your device is not supported, contact Samsung Product Support for further assistance.

IMPORTANT: You may need your device model name, S/N number, or IMEI number in order to proceed. This information can be found on the label underneath your device battery.

WARNING: This process permanently deletes all personal information from the device. The information will not be recoverable if you proceed with this process.
