    Want to install the latest Android 4.0.3 leak on your Galaxy S2? Well we are going to show you how today. In this new build Samsung made several improvements, mostly speed and over all touch screen improvements.

    Disclaimer: Android Authority is not responsible for any damage to your device while flashing this unofficial leak.

    Pre-Installation tips:

    1. Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc.
    2. If you have Samsung’s PC software Kies installed, un-install it first because it may interrupt the flashing process.
    3. Drivers! — it’s important you’ve the proper drivers installed. Download links below: 32 bit (x86) Windows |   64-bit (x64) Windows

    Install XXKPA Firmware on Galaxy S2 to get Android 4.0 ICS

    1. Download XXKPA firmware. Filename: I9100XXKPA_I9100OXAKPA_OXA.rar. Size: 353 MB →Download Link. [password: samfirmware.com]
    2. Extract the downloaded file ‘I9100XXKPA_I9100OXAKPA.rar’ of XXKPA firmware to get these 7 files (the file-names may end with .tar instead of md5 as the file extension is hidden, so don’t worry):
      1. GT-I9100-MULTI-CSC-OXAKPA.tar.md5
      2. I9100_CODE_I9100XXKPA_CL51925_REV02_user_low_ship.tar.md5
      3. I9100_EFS_I9100XXKP9_CL45181_REV02_user_low_ship.tar.md5 [not to be used]
      4. I9100_KERNEL_I9100XXKP9_CL45181_REV02_eng_mid_ship.tar.md5 [not to be used]
      5. MODEM_I9100XXKPA_REV_02_CL1094591.tar.md5
      6. Odin3 v1.83.exe [For windows only. Double click to run this file when asked in step 5 below. Admin privileges will be required!]
      7. u1_02_20110310_emmc_EXT4.pit
    3. Disconnect your phone if it’s connected to PC.  Switch Off your phone. Wait for vibration to confirm complete switch off.
    4. Now, put the Galaxy S2 in Download Mode — press and hold these keys together: Volume Down + Home + Power. You’ll get an options screen. Press Volume Up now to go to download mode (which is also called Odin mode). This is required to install the XXKPA (or any other firmware) using Odin PC Software.
    5. Open Odin (from step 2.6) — double-click the Odin3 v1.83.exe.
    6. Connect your phone to PC now. You should get the message “Added! !” under the Odin’s message box in the bottom left. If you don’t get this message, then probably there is a problem with drivers. Make sure you’ve proper drivers installed. See point 3 above under ‘pre-installation tips’.
    7. Select these files in Odin at respective tabs:
      1. Click the PDA Tab, and select I9100_CODE_I9100XXKPA_CL51925_REV02_user_low_ship.tar.md5 (from step 2.2)
      2. Click the Phone Tab, and select MODEM_I9100XXKPA_REV_02_CL1094591.tar.md5(from step 2.5)
      3. Click the CSC Tab, and select GT-I9100-MULTI-CSC-OXAKPA.tar.md5 (from step 2.1)
      4. Click the PIT tab, and select u1_02_20110310_emmc_EXT4.pit (from step 2.7)
    8. Important! On Odin, make sure Re-Partition, Auto Reboot and F. Reset Time check boxes are selected. Do not touch any other check box or tab or anything, except as was required in step 8 above.
    9. Double check everything said in step 7 and 8 above. [And, do not use the files in step 2.3 and 2.4 anywhere in Odin]. This is my Odin’s screen while I flashed the XXKPA on my Galaxy S2 — your Odin’s window should look real similar to this:

    10. Now, hit the START button to start flashing of XXKPA Android 4.0 firmware on your Galaxy S2. When the XXKPA Android 4.0 firmware has been installed by Odin on your phone, your phone will automatically reboot — and when you see the Samsung logo, you can safely unplug the cable. Plus, you’ll get a PASS (with green background) message in the left-most box at the very top of the Odin. In case it says FAILS (with red background) or nothing seems to be happening, check the Important Note below after step 11 to know what to do.
    11. When it has restarted, your Galaxy S2 will be running Ice Cream Sandwich (ICS) with version being Android 4.0.3, build being XXKPA and Samsung’s custom UI TouchWiz 4 atop it. Check out your Galaxy S2’s android version here: Settings » About Phone.

    IMPORTANT NOTE: If Odin doesn’t seem to be progressing/doing anything for more than a minute, or fails to complete the process, do the following:

    Disconnect the phone from the PC, close ODIN, remove battery, re-insert it, turnphone on in Download mode again, and do the procedure again from Step 5.

    • Leamsiylre

      this Ice Cream Sandwich 4.0.3 is a Beta Version of Android ICS for S2… it is really un stable and has many bugs like always hanging, un wanted virabrations and suddenly turning on of natification tones… some apps like viber is not working… battery life is even worse…

      remember this is only a LEAK and not Official Release.. this means it was leak just to get the public’s comments and feedback so developers can look where to improve the Firmware…

      better to update on Android 2.3.6 Lightning ROM XXKJ1 if im not mistaken or the one im using rigth now is XXKL1… really fast and stable plus extended battery life of up to 2 days…

      • doodz
