Gotten bored of the same old Android UI on your AT&T Galaxy S2 Skyrocket and would like to try out something different? If the answer is yes, the MIUI ROM is exactly what you need to try. MIUI features a unique interface and look that’s very different from default Android, with other features such as inbuilt theme changer (with hundreds of fan-made themes available), privacy protection features, custom-built apps such as a home launcher, music, contacts, messages etc, and lots more.

MIUI is also based on Android 4.1 Jelly Bean, so you also get the smooth and fluid interface of Jelly Bean, and other features such as expandable and actionable notifications, a new Google Search experience with voice recognition and Google Now information cards, smart and intelligent keyboard, etc, making it the best version of Android to date.

Keep in mind that this is not an official Samsung ROM. It’s a custom ROM that is under development and may have a few bugs and issues, and some things may not work properly and some stock Samsung ROM features will not be available.

Read on to find out how you can install the MIUI ROM on the AT&T Galaxy S2 Skyrocket.

How to Install MIUI Jelly Bean ROM on AT&T Skyrocket

  1. This procedure will wipe all your apps, data and settings. Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    NOTE: Don’t forget to at least note down your network’s APN settings, which are required to make mobile data work. Go into Settings » More » Mobile Networks, click on the APN that is in use, then note down the setting for each field. While APN settings should be automatically restored from network, you can enter them manually if needed to make mobile data work. You can also find your APN details → here.
  2. [Important!] Install the ClockworkMod (CWM) Touch recovery on the phone by following the guide → here. 
  3. Download the latest version of the ROM from the source page.
  4. Download the DarkSide SuperWipe file, which is needed for wiping the phone internal partitions (does not delete personal files on the SD cards) before installing the ROM.
    Download Link  |  Filename: DARKSIDE.SUPER.WIPE_EXT4.zip
  5. Copy the 2 zip files downloaded in steps 3 and 4 to the internal storage (not to the microSD) on the phone (do not extract the files).
