Folks, just a few days ago, another Android 4.0.3 Ice Cream Sandwich firmware leaked for the Galaxy S2, named XXLP2. And for some reason, we weren’t able to post a step by step guide to install XXLP2 on Galaxy S2 that time. So here it is, now.

As for what has changed in XXLP2 from earlier builds, like XXKP8/XXKPA:

• Interface: Nothing compared to XXKPA.
• Battery: Battery feels better.
• Faster: Phones feels faster.
• Touch: Touch response is better.
• Overall: Firmware more stable but still with some bugs.
• Facelock: Working.
• Task: Task manager is back.

Read on to find out how to flash this firmware on your Galaxy S2.

Warning!

Compatibility

This rom and the guide below is compatible only and only with Galaxy S2, model number i9100. It’s not compatible with any other device. Check your device’s model number in Settings » About phone.

Pre-Installation tips:

1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
2. If you have Samsung’s PC software Kies installed, un-install it first because it may interrupt the flashing process.

7. Connect your phone to PC now. You should get the message “Added! !” under the Odin’s message box in the bottom left. If you don’t get this message, then probably there is a problem with drivers. Make sure you’ve proper drivers installed. See point 3 above under ‘pre-installation tips’.
