How to Flash/Install I9100XWLP2 Upgrade Samsung Galaxy S2 to Official Android ICS 4.0.3 Ice Cream Sandwich

This is a step by step procedure  how to manually upgrade your Samsung Galaxy S2 to Android 4.0.3 Ice Cream Sandwich with the firmware build I9100XWLP2.  The  official firmware update released in Russia for Galaxy S2 users,  another ICS 4 firmware build number after the firstly released I9100XXLPQ in Europe and Asia.

This method is only for those who encountered issues and can't upgrade on Kies. To have smooth firmware flashing in Odin, do a factory reset first on your device, just ensure that you already have a back-up copy of all your important files stored from the device. This procedure is considered risky and should not be taken slightly. But this is very useful when Kies ignored you from upgrading your Galaxy S2 to Android 4.0.3 Ice Cream Sandwich. Advance users used this method instead of Kies, for they always modified their Galaxy S2 to any available custom ROMs developed by 3rd party android developers. The following instructions below will show you a simple step by step guide on how to do it.

Disclaimer: Use this method and procedures at your own risk! We shall not held responsible if something happens to your device by following this guide.

Do the following preparation before flashing.
- Ensure that the battery is fully charge. A power failure will cause a fatal error in your device.
- Make a back-up copy of all the important files stored from the phone. Your saved contacts, SMS, APNs (internet settings), Apps, bookmarks and etc. will be deleted after flashing. Although the firmware file we are using on this guide is a non-wipe version, meaning – your important files will remain and will not be cleared, but it is very important to have a back-up copy just in-case something went wrong while flashing.
- You need to have the Samung Kies installed in your PC or download the Samsung driver, just to ensure that the USB driver for Galaxy S2 is also installed. But disable it when you are about to upgrade using Odin, for it will interrupt the flashing process.
- You have a PC or laptop that runs in Windows OS, Odin will only work on Windows operating system. Ensure that it has a good USB serial port 100% working.
- Use a good USB cable wire that is built for Galaxy S2.

- Grab Odin downloader tool.
- Download the original I9100XWLP2 stock firmware. Make sure to select the right firmware according to your country or region. European countries can use the Poland stock ROM with CSC file I9100OXALPQ for it supports all European languages. As for this guide, we used the Poland firmware. The default language is Polski but you can change it into your local language after flashing or installing.
