Of course, this particular update will remain an optional one, but I do not see any reason not to give it a go. Right now, the only installation method available would be to go through Samsung’s Kies software, so forget about refreshing your handset for an Over The Air (OTA) download. The manual download is known as T989UVMC6 where it will bump up your Android version to 4.1.2, although you would do well to ensure that your Galaxy S2 is fully charged and connected to a local Wi-Fi network instead of relying on your data plan, since the entire update tips the scales at approximately 756MB. A truly great way to start off your Monday, no?
