Manually Install The Official Android 4.0 Ice Cream Sandwich Update On Samsung Galaxy S II
By on March 13th, 2012

Earlier today, Samsung announced that Galaxy S II owners in South Korea, Poland and some other regions of the world will get to taste the official Ice Cream Sandwich update on their handset.

Since then, the official firmware (XXLPQ) has been pulled from Samsung’s server by the folks over at Samsung-Updates.com for Galaxy S II owners in other regions of the world to flash and enjoy.

Below is a step-by-step guide on how to install the official LPQ Ice Cream Sandwich firmware on the Galaxy S II -:

Since this is an official firmware, users will not lose their warranty if they flash this firmware on their phone. Their phone will however be wiped clean of all data, so please make a backup of your data before proceeding futher!

Step 1: Download the official XXLPQ firmware from here (Mirror 1 2, 3 and a torrent link) and download ODIN from here. Extract the LPQ firmware zip file inside a new folder on your desktop.

Step 2: Switch off your Galaxy S2 and re-insert its battery. Now boot your Galaxy S2 in Download mode by pressing the Volume Down + Home + Power button simultaneously. Your phone will then show you a warning. Simply skip the warning by pressing the Volume Up button.

Step 3: Start ODIN, and then connect your Galaxy S II to your PC. ODIN will then detect your phone, and display a random COM:ID number inside a glowing rectangle box. Click on the ‘PDA’ button, and select the ‘I9100XXLPQ_I9100OXALPQ_I9100XXLPQ_HOME.tar.md5’ file. It is the only file inside the zip file that you downloaded in Step 1 above.

Step 4: Do not touch any other option. Simply press the Start button and wait for ODIN to flash the firmware.

The firmware is pretty big (600MB extracted), and so ODIN will take some time to flash it. The first boot after the flash will also take considerable time. It took nearly 10minutes for my Galaxy S II to start after I flashed the firmware.

Update: Added some mirrors for the firmware download link. For root access, download and flash Siyah Kernel LPQ and flash via ODIN.

Update 2: If your phone is stuck at the S boot logo for more than 15 mins, re-insert the battery and re-do the steps mentioned above.

    Hey, thx for the guide. I had to manually update since I for some months experimented with flashing.My ICS is now up and running. I have however a problem. The telephone wants to setuo for automatically software update in the future. I have to agree to some given terms, but I cannot. It comes back saying that the registration failed…In the top bar there is constantly a icon for software update. Is there anyeay to turn this of?

    • http://www.facebook.com/profile.php?id=1168593667 Rajesh Pandey

      You need to have root access to remove that ‘Software Update’ bar from the notification bar. I have updated the guide with link to a Rooted kernel.

    Do I need to wipe data and do factory reset before or after flashing as many users reported FCs and bootloops? and is it just 1 file that need to be flashed? currently I’m on DDKL1 and using it with t mobile in usa?/.

    • http://www.facebook.com/profile.php?id=1168593667 Rajesh Pandey

      No. Not needed.

      Rajesh Pandey yes it is and i am running an original 2.3.5 and want to update to xxlpq… ive’ been lookin for a solution to this error since 2 hours and i think it has something to do with the formatting of either the phone memory or the ms card … Since i am a newbie i do not know if i am on the right way

    • http://www.facebook.com/profile.php?id=100000099517223 Petar Obicham Bianka Todorov

      Rajesh Pandey how wud we be able to restore our data back as kies is not supporting ics here in india ?

    • http://www.facebook.com/profile.php?id=1168593667 Rajesh Pandey

      Rahul Sharma If you are upgrading from a Gingerbread based firmware, your handset will not be wiped clean of any data.

    Hello Rajesh, I did what you mentioned above and the ICS installed. However after this it wont detect my memory, most of the apps crash , the camera wont open and give me a message to turn off USB storage before using the camera. It also gives an error saying android.process.media.Can you help me out here.

    • http://www.facebook.com/profile.php?id=797958451 Syed Ashfaq

      Chk for team hacksung ics build 16 on xdadeveloper forums. Thr r various other custom ics roms on this forum but this one is d most stable

    • http://www.facebook.com/profile.php?id=505259407 Abrar Khan

      @[797958451:2048:Syed Ashfaq] i kind of fixed it . i found out that the SD card was messing up and during media scanning it would make the process stop. The whole process would also stop the USB storage reading. I removed the card, inserted it in my BB, formatted it and put it back…..at first the phone didnt hang, the media scanning was successful and it read the SD card. Now its back to normal.

    do we risk “bricking” the phone when we install updates this way?

  • http://www.facebook.com/profile.php?id=1590313459 Martin Walubita Mubita

    I did everything successfully and phone is working fine but Kies says my device cannot be updated through Kies why?

    • http://www.facebook.com/profile.php?id=1168593667 Rajesh Pandey

      You are already on Ice Cream Sandwich now. What will KIES update your phone to now?

    hey Rajesh
    i am trying to extract the files but it keeps coming up with fatal error file corrupted, downloaded the file twice, got any ideas as to why this is happening?

    • http://www.facebook.com/profile.php?id=1168593667 Rajesh Pandey

      Maybe the file is not getting downloaded properly. Download again!

  • http://www.facebook.com/profile.php?id=100001830192377 Timmy Guy

    Hi I did use this and it works perfectly. But still I havn’t noticed the main changes. ie. grouping of apps, the slider menu, the icon change, wallpaper and clock change? why is it so?

  • http://www.facebook.com/profile.php?id=100001830192377 Timmy Guy

    Hi thanks..This is working but I have few queries. In youtube videos I see a samsung galaxy s2 with different icecream, Like clock getting changed, grouping of apps, slider menu etc but this has none of these. Why is it so?

    • http://www.facebook.com/profile.php?id=1168593667 Rajesh Pandey

      That must be a custom ROM or CM9. This is Samsung’s version of Ice Cream Sandwich, and that’s how it will look. You can try out Nova launcher or Apex launcher from the Play Market for that grouping of apps, slider menus etc.

    does this pprocedure means “i will b rooting my phone”?

    • http://www.facebook.com/profile.php?id=1168593667 Rajesh Pandey

      No. You don’t need root access to flash the firmware. Also, your warranty will remain intact as well!

  • http://www.facebook.com/profile.php?id=703519812 Gautham Vasudevan

    Hi. Thanks for this update. It does work. But my problem is I cannot get all the features of the icecream sandwich OS that I see in nexus phone. For eg, the icons and background still remain like the prev android version is S2, I cannot see the slider bar and the new grouping features of app in the oS I have downloaded. WHy is that so?

  • http://www.facebook.com/profile.php?id=784760067 Kameel Khaldy

    Thank you Rajesh,
    It took less than 10 minuets to have the ICS intalled in my sii.

    For which samsung galaxy s2 ICS software is not applicable? For i9100 or for i1900G!

    Hi, my Samsung galaxy s2 is stuck in firmware 2.3.4 and cannot update through KIES or via wifi on the phone itself. Its pretty annoying and I really want to get Ice cream sandwich, or at least some sort of update being shown. I was just wondering what you think I should do? Do you think doing the above will work?

  • http://www.facebook.com/profile.php?id=100003165337790 Anthony Alder

    mi phone is stuck in the S logo, I did everithing you told me.

  • http://www.facebook.com/profile.php?id=696763260 Vishal P.Dhuru

    is it working for I9100G too?
