Galaxy S2 users will be happy to learn that an official firmware known as the Gingerbread 2.3.6, is already available. This will be the perfect time to finally update your Galaxy S2 GT I9100 to make the most out of your device. Before doing so however, make sure that you have already made a back-up on the data on your phone since there is an existing possibility of data corruption or loss in the process of updating to the new firmware. If you were able ti make a back-up, you can replace all the date in any case any damage occurs.

You can back up images, videos and other types of files by copying them to an external SD card. Notes on the other hand, can be saved in your mail so that you can restore them manually after the update. You even have the choice of making a back up of all call logs, SMS messages, and contacts on your device by syncing them with Gmail application.

Before starting with your phone’s update, make sure that it is completely charged so that it will not die out in the middle of the update process. All firewalls should also be closed, as well as antivirus suites, since they will interrupt the firmware update process. Another important setting that you need to take note of would be your device’s APN settings, which you can manually jot down on a piece of paper so that you can reconfigure your phone after the update process.
