Most ICS-based custom ROMs for Samsung Galaxy S2 are buggy and unreliable. Devs are pointing fingers at Samsung who until now hasn’t released stable builds for Android 4.0. If you can’t compensate function for that handsome Ice Cream Sandwich look, your best bet is CheckROM RevoHD by LeoMar75. The latest as of today is CheckROM RevoHD v6 which is based on XWLA4, an original Gingerbread 2.3.6 Samsung firmware. When the official ICS update for Galaxy S2 is released, this custom ROM will probably be updated but its customization features will surely stick around.
Supported Devices
Samsung Galaxy S II i9100 (International version)
Features
The best feature of CheckROM RevoHD is its KitchenPro app. While you can download it at Google Play Store (see download link at bottom of post), it’s limited to CheckROM RevoHD users. The custom ROM’s latest version has it pre-installed. You can then update it at Google Play from there. KitchenPro features include:
• Download/install boot animations
• Download/install modems
• Download/install themes
• Download/install widgets
With KitchenPro, you can fully customize your phone and imitate the look of Ice Cream Sandwich without having to install any of those buggy, ICS ROMs. And if you get tired of it? Just download whichever theme you feel like having.
Other features of CheckROM RevoHD include:
• No wipe
• CF root kernel (CF-Root-SGS2_XW_OXA_LA4-v5.0-CWM5). This kernel roots your phone and adds Clockworkmod Recovery and CWM 5.
• VOIP for Wi-Fi
• XWKL1 modem for better battery life
• Most Samsung apps and widgets are removed
• Battery mod
• Swipe to remove notifications
• New control panel under Settings > Display Settings
