New Android 4.0.3 Ice Cream Sandwich Based Firmware For Samsung Galaxy S2 Leaks (+Installation Steps)
By on December 31st, 2011
In the last month, two Android 4.0 Ice Cream Sandwich firmware for the Samsung Galaxy S2 had leaked on the Internet. However, both the firmwares were clearly in alpha stage, and were not usable on a day to day basis.
Now, the folks over at SamMobile have released two new Android 4.0 Ice Cream Sandwich firmware for the Galaxy S2. Like the previous leaked firmwares, these firmware also have Samsung’s TouchWIZ UI running on top of Ice Cream Sandwich. While one of the firmware (KP4) is based on Android 4.0.1, the second one (KP8) is based on Android 4.0.3.
While both the firmwares are still not stable enough for daily use, it is still enough to give users a taste of how the official Ice Cream Sandwich update from Samsung will look like.
Readers can install the leaked Ice Cream Sandwich firmware on their Galaxy S2 by following the instructions mentioned below -:
You will not lose your warranty, if you have not rooted S2. Before proceeding with the steps below, please make sure that you have backed up all your important data on the phone like call logs, messages and apps, since your phone will be wiped clean of all data once the firmware is installed. Rooted users can use Titanium Backup to backup all their apps, and non-rooted users can follow this guide to partially backup their apps. Your data on the internal (16GB memory) or on the external SD card is safe, so no need to back them up. 
Step 1) Download the leaked Android 4.0.1 Ice Cream Sandwich KP4 firmware file from here, or the Android 4.0.3 based firmware from here. The password of the zip file is ‘’ without quotes.


Step 2) Download ODIN from here. Make sure you have KIES pre-installed since it will automatically install all the required drivers.
Step 3) Now extract all the files from the zip file you downloaded in Step 1 inside a new folder on your desktop.

Step 4) Start ODIN, and click on the PDA file. Now navigate to the new folder on your desktop inside which you had extracted all the files from the zip file which you downloaded in Step 1. Select the file with ‘Code’ in its name (I9100_CODE…tar). Similarly, press the Modem button in ODIN and select the file with ‘Modem’ in its name (MODEM_I9100KK).
Lastly, press the CSC button and select the tar file with CSC in its name (GT-I9100-MULTI-CSC).
Step 5) Switch off your Galaxy S2 (I9100) and re-insert the battery. Now, press the Volume Down + Home + Power button simultaneously to boot into Download mode. A warning will come up about your warranty being void. Simply press the Volume up button to skip it.

Step 6) Your Galaxy S2 will then display a yellow exclamation mark. Connect your phone to your PC, and ODIN will then detect it. When detected, ODIN will display a random COM No. in a glowing box in the ID:COM section.

Step 7) Now simply press the ‘Start’ button and wait for ODIN to flash the leaked Ice Cream Sandwich firmware on your phone!

That’s it! You have successfully managed to install the leaked KP4/KP8 Ice Cream Sandwich firmware on your Galaxy S2!
