Galaxy S2 I9100 Gets Official Android 4.0.4 XWLPY ICS ROM [How to Install and Root]

The latest Android 4.0.4 Ice Cream Sandwich (ICS) official firmware is now available for Galaxy S2 I9100 users on the H3G network over Samsung KIES in the UK. However, those users who missed the official OTA (Over-The-Air) update from Samsung can now download and install it manually using this guide.

As the ROM is an official release based on the H3G carrier-built-custom-software, it will include bits of H3G third-party apps and will not feature the pure stock Android experience. However, the interested users in UK may proceed with the ROM installation.
