How to Update the Samsung Galaxy S II with the Official Indian 4.0.3 ICS Firmware

If you happen to own a Samsung Galaxy S II and you also happen to live in India this might just be your lucky day. It is still unknown when Samsung will decide to push the Android 4.0 ICS update to the Indian Galaxy S II, but thanks to a leak you can now flash the file that should come via KIES as a brand new custom ROM. Unfortunately there is still no way of applying the update automatically, so for now you will have to use the manual install procedure. This how to is a detailed explanation of how this manual procedure works so if you are anxious about flashing your Galaxy S II with the Indian version of the ICS software, read the lines below carefully.

Unlike many other custom updates, the XXLPQ one can be applied to a rooted device and because it requires a computer it can also be used as a nice tool to revert back to the unrooted stock version if you have to send your Samsung Galaxy S II to warranty for example. This means that your device can be either rooted or stock before the update, because at the end it will be running with the stock version of ICS Samsung is going to push out officially in the next couple of weeks. In any case you should take note of our disclaimer: As with any software that is not our own creation, we must warn you that you cannot hold us responsible for any damage that might occur to your device by following the procedures in this guide. However, we will try to help you sort out any glitches or problems that might arise by following the steps in this guide to the extent our knowledge limits us.

We will begin this tutorial with a relatively simple goal, that of backing up your personal data. While this update may not erase it it is always better to keep a backup of the important stuff just in case. All you have to do is to use the apps below and make sure that you remember what you have done, because after a successful update you will have to restore that data.

  • Text messages – We will back them up with this application : SMS Backup & Restore
  • Phone Contacts –  You can simply synchronize them to your Gmail account or export them to the micro SD card as a .vcf file
  • Call Log – We will use the following application to backup your call log : Call Log Backup and Restore
  • Pictures, Music, Videos, and other files – Simply copy them to your microSD card.
  • Internet & MMS Settings – Write down all the settings from this path “Applications > Settings > Wireless and Network > Mobile Networks > Access Point Names”

There are also a couple of other hardware related requirements that must be met before attempting the update process. These ones will serve as a a benchmark to make sure your phone is in its best shape before it undergoes this procedure:

  • You need to charge your device to full or to a minimum of 70% to ensure that it will not power off during the updating process.
  • Enable the USB debugging in your Samsung Galaxy S II. This can be done from the following: Settings > Applications > Development > USB debugging. The USB Debugging option should be ticked.
  • Turn off all your anti virus and other security related software because it might interfere with the program we are using to update your Galaxy S II.

This last part is the hard one because it covers the updating process in simple easy to understand steps. Even if you know your way around this update please read the steps below and make sure you don’t skip any of them. You must also follows the lines below in order to ensure that everything gets installed properly:

  • The first step we need to take is to download this Official Indian ICS 4.0.3 Package to your computer and then to extract it to somewhere easily accessible like the desktop. Also open the Odin program in the extracted folder.
  • The second step is a bit complicated as it involves powering off your Samsung Galaxy S II and then rebooting it into Download mode. The Download mode of the Samsung Galaxy S II can be entered by pressing the Volume Down key, the Home key and the Power On key simultaneously after the device has been shut down. You will be able to recognize the Download mode by the big triangle with a working Droid inside.
  • The third step is fairly simple and as such you only need to connect your Samsung Galaxy S II in Download mode to your PC which is already running the Odin program we opened earlier with the original USB cable. It may take a couple of seconds for the program to recognize your device so you can check when it is ready by looking at the color of the ID: COM window. If it is yellow you are ready to proceed. If the ID: COM windows does not run yellow you should check if you have installed the USB drivers for the Galaxy S II and if you have enabled the Samsung KIES option on your device from the “Settings > Wireless & Network > USB Settings” path.

  • The fourth step is the last one and it is easiest as all you have to do is press the Start button in Odin and wait 5 to 10 minutes for the updating process to finish.

Odin will tell you when the flashing procedure has been finished and if it has been successful, but the only way of seeing it is to restart your phone normally if it does not restart automatically. If the update process fails at some point do not panic as all you have to do is pull out and reinsert the battery and then try again. If it completes without a hitch you have successfully updates your Samsung Galaxy S II to the official version of the Android 4.0 ICS software for India a couple of weeks before the official update.
