Following the release of the SHW-M440S firmware update for Samsung’s Galaxy S3 in South Korea users will now be able to update their Galaxy 3 to the latest firmware in order to get the most out of their phone. While users will generally be able to update their device through the on-board KIES service once the update hits your network area you can also update it manually through our instructions below in order to have more direct control over your device. This can be particularly helpful if you have already unlocked your phone and are using customized software on it that may interfere with standard KIES operations.
Disclaimer: As with any update to software and operating systems running this service can potentially have a harmful effect on your phone, causing partial or total loss of data and usability. Because of this anyone looking to do a manual update of their phone should be aware of the risks involved and take precautions against them before proceeding at your own risk. Please also note that this guide is for installing the firmware on your rooted phone only. To check and see if your phone has been rooted download the free root checker from the Google Play store now.

Backup and Other Precautions:
Before proceeding to update your phone always be sure to backup all data prior to your upgrade in order to ensure that no information is lost along the way. This can include :-
- Backing up your SMS and call records to make sure that you have accurate files at all times
- Backing up your contacts, phone settings and media
- Backing up any third-party software applications you may have installed (especially those such as WhatsApp, WeChat or other messaging software)
- Backing up all network connectivity and other data to ensure no network loss (including GPRS, 3G/4G settings, WiFi settings and other network protocols).
Most backups of important data such as contacts and media can be achieved through using standard phone synch software with your computer. For a more complete backup, however, we highly recommend using a third-party backup program such as ClockWorkMod in order to generate a complete backup image of your device in order to allow for a complete restoration should any issues occur. Additionally, before initiating any update be sure that your device is fully charged in order to prevent any unnecessary data losses from occurring.

Step 7: Ensure that “Auto Reboot”, “F. Reset Time” and “Re-Partition” (if .pit was selected in Step 6) are checked.
Step 8: Hit “Start” in ODIN and wait for your update to complete. This make take a few moment for your phone to finish updating. Do Not disconnect your phone from your PC during the update process or you may run the risk of corrupting all data on your phone and causing extensive damage to your file systems. If a disconnect occurs at any time be sure to attempt resuming the above steps to repair any installations that may have been added to your phone.
Should you have any troubles with the update process be sure to return your phone to its previous settings using your backed up information. If you did not backup any information or did not backup the data fully you may wish to complete a full factory reset of your device to ensure its usability.
As with any update, always be sure to test out all previously used apps to ensure compatibility with your new firmware before attempting to regularly use them. This may require updating some applications to their latest versions in order to make sure they can properly interact with your firmware and be able to function properly without any complications arising.
