Sony Ericsson releases an alpha Android 4.0.1 Ice Cream Sandwich ROM for Xperia Arc S, Xperia Neo V and Xperia Ray available for download on their Developer World website.

This ROM version is strictly targeting advanced developers (this software is not intended for ordinary everyday usage), as it only has a limited set of features working (you can not make any phone calls, the modem, Wi-Fi, Bluetooth, FM-radio and ANT+ is turned off, and GMS apps are not included either).

For your enjoyment Sony Ericsson shared a demo video clip of the alpha Android Ice Cream Sandwich official 4.0.1 ROM running on Xperia Arc S (LT18i). Check for the video at the bottom of the post.

Here are the intructions from where to download the ROM and how to install it on your Sony Ericsson Xperia smartphone:


Note:
Please note that it only works with Xperia™ arc S, Xperia™ neo V and Xperia™ ray.

  1. Make sure your phone is running the latest software release, which is build number 4.0.2.A.0.42. If not, upgrade your phone through PC Companion. If you can’t upgrade to this build number, it is not possible to try the Ice Cream Sandwich alpha ROM for Xperia™ phones.
  2. Go to unlockbootloader.sonyericsson.com  and unlock the boot loader of your phone. To do this, you must read through and agree to all the legal and warranty conditions that apply.
  3. Download the Ice Cream Sandwich alpha ROM for Xperia™ arc S  (132MB), the Ice Cream Sandwich alpha ROM for Xperia™ neo V (131MB) or the Ice Cream Sandwich alpha ROM for Xperia™ ray  (132MB) depending on your phone model.
  4. Extract the downloaded zip file to your Android Fastboot directory. For example: ..\android-sdk\fastboot\Xperia_arcS_ICS_alpha.
  5. Open a command prompt and go to your Fastboot directory: ..\android-sdk\fastboot\
  6. Flash the three alpha ROM files one at a time using Fastboot. Use these three commands (replace the folder name if you are using Xperia™ neo V or Xperia™ ray):
    • fastboot flash boot ..\Fastboot\Xperia_arcS_ICS_alpha\boot.img
    • fastboot flash userdata ..\Fastboot\Xperia_arcS_ICS_alpha\userdata.img
    • fastboot flash system ..\Fastboot\Xperia_arcS_ICS_alpha\system.img
  7. Once done, please reboot your phone.
