Samsung will start to push out the Android 4.0.3 ICS update to Galaxy S2  in Korea and some other regions, it seems to focus on devices in Hungary, Poland and Sweden before starting to roll out in the United Kingdom during the week commencing on March 19^th. So it tells that Galaxy S2 user will taste ICS update soon, but actually individual networks also need to approve the software updates and put it through vigorous in-house testing to ensure it plays nicely with their own branded software, so official update has pushed but it can still quite some time before users can use it.

If you don’t have ability to wait, here’s guide install, but keep in mind that tinkering with OS can be difficult , you can face some unexpected issues in extreme cases cause your smartphone to become nothing more than a beautifully crafted door stop therefore follow carefully.

Requirements

However if you’re interested please note that below guide may not work on all Galaxy S2 variants, Samsung mentioned just Galaxy S2 but not mentioned of US variants. Galaxy S2 LTE devices are not supported. To install this update latest Samsung Kies must be installed on your PC, it contains all of the required USB drivers. Please turn the USB debugging on, just go to ‘Settings >> Applications >> Development‘ and check the relevant box.

DISCLAIMER: The below method is bit risky and we will not be held responsible if you lose data or your device gets damaged in the following of this guide so please proceed at your own risk.

Guide

Step #1: Download Odin here.

Step #2: Possibly the most important element in this whole process is the Android 4.0.3 firmwarefile, which you will obviously need to download from this link, Size 300MB.

Step #3: Extract the downloaded file into a folder.

Step #4: Now that we have the necessary files needed for the process, it’s time to throw them together to perform magic. Open up the ‘Odin‘ application and click the big button which is labeled ‘PDA‘ (located under the heading ‘Files [Download]). Navigate to the extracted folder containing the downloaded Ice Cream Sandwich files and locate the file which is appended with the ‘.md5′ extension. Odin will relish this and eagerly prepare the file for the installation goodness that is to follow,

Step #5: Now gently prepare the Galaxy S II device for what is about to happen. After making sure the handset is totally turned off, turn it on by pressing the ‘power‘, ‘volume down‘ and ‘home‘ buttons together. A rather scary warning sign will appear on the screen, giving you the opportunity to back out now if you so desire (don’t worry, we won’t judge you if you get cold feet). If you decide to proceed, press the ‘volume up‘ button to dismiss the warning and activate the device’s download mode.

Step #6: Now you need to connect the Galaxy S II to the computer using the USB cable, skipping back to the Odin application that is running and wait for it to detect the connected device. If nothing happens, make sure you installed the required Kies application.

Step #7: Underneath the ‘Control Panel‘ heading in Odin lies a big button which says ‘Start‘. If you still have the courage, and everything has gone to plan so far then press it and give your Galaxy S II the treatment is so sorely deserves. There you have it. A relatively painless and simple, but unofficial method to install Ice Cream Sandwich on the Galaxy S II handset.
