After a long wait and after going through many leaked Android 4.0 ROMs form Samsung we have finally received the official Android 4.0 ICS for Galaxy S2.

XXLPQ is officially released for the Nordic regions with other regions getting the update in coming days. People living in Nordic region can upgrade their device to the latest OS through Kies. But for people who aren’t from that region they can also enjoy the update after they have gone through this guide.

Before we start with the process of flashing to this final build let me point out that there are certain features missing from this final release that were present in the beta leaked ROM’s. Now don’t get worried because the features are mostly related to the 3D animation regarding the swiping the home screen and also the widget drawers.

I am sure they aren’t something that will be missed when you are done updating. So without any further distraction let’s get started.

Things You Need Before Flashing

  • Odin v1.83
  • XXLPQ Firmware
  • USB Cable
  • CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5

  1. Download the firmware XXLPQ firmware and it should be around 382.43MB
  2. Make a NAND droid backup of your current installation from the recovery mode.

  10. Now click the PDA button and browse to the folder where you have extracted the firmware and select it.
  11. After selecting the file click on Start to begin the flashing procedure
  12. Wait for 10min for the flashing to complete and your phone will reboot and android 4.0 ICS will load and follow the procedures to set up your device.
