DISCLAIMER: Redmond Pie will not be held responsible if you lose data or your device gets damaged in the following of this guide. Proceed at your own risk.

Before you begin, please note that you will have to be on a rooted Galaxy S II International Version. As far as we know, this doesn’t work on variants such as the Epic 4G Touch.

Step 1: Download the following files:

  • ODIN 1.83 [HotFile]
  • Android 4.0.3 ICS I9100XXLPB [SamMobile]

Extract the contents of the ICS ROM and place them on the desktop for easy access later on.

Step 2: Shut down Samsung KIES in case you have it open. If you don’t shut it down, it will interfere with ODIN.

Step 3: Launch ODIN.

Step 4: Shut down your Galaxy S II. Press and hold Volume Up + Home + Power buttons to enter Download Mode.

Step 5: Connect your GS II with your PC using a USB cable. ODIN will detect it.

Step 6: From ODIN, click on PDA and select I9100_CODE_I9100XXLPB_CL99600_REV02_user_low_ship.tar

Step 7: Similar, click on CSC and choose GT-I9100-MULTI-CSC-OXXLP5_RST.tar. Click on MODEM and choose MODEM_I9100XXLPB_REV_02_CL1101286.tar

Step 8: Click START to begin the flashing process. ODIN will now flash the ROM to your device.


If you followed the steps correctly, your Samsung Galaxy S II will boot into an official, leaked beta build of Android 4.0.3 Ice Cream Sandwich. For queries, check out the comments section over on SamMobile’s post.
