Follow the instructions below to download and install the ROM. Please note that it only works with Xperia™ arc S, Xperia™ neo V and Xperia™ ray.
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 ROM for Xperia™ phones.
Go to 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. Download the Ice Cream Sandwich or Extract the downloaded zip file to your Android Fastboot directory. For example:
Open a command prompt and go to your Fastboot directory:
Flash the threeROM 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 ..FastbootAndroidsRoms-Android40_SonyXperiaboot.img
fastboot flash userdata ..FastbootAndroidsRoms-Android40_SonyXperiauserdata.img
fastboot flash system ..FastbootAndroidsRoms-Android40_SonyXperiasystem.img
Once done, please reboot your phone. Important information
Since this is far from the final software upgrade roll out, there are a few things to pay close attention to before you download and install the ROM:
You should be an advanced developer with extensive knowledge in how to install, and switch between different ROMs. If you are a consumer without these developer skills, then we strongly recommend you not do try this as you may damage your phone.
You must be using Xperia™ arc S, Xperia™ neo V or Xperia™ ray, running the latest Sony Ericsson software release (which is 4.0.2.A.0.42). Please note that you can't use the original Xperia™ arc or Xperia™ neo, as they have different partition layouts.
You must unlock your phone using Sony Ericsson's Unlock boot loader service, and agree to all the legal and warranty conditions that apply. Please note that you may void the warranty of your phone and/or any warranty from your operator if you unlock the boot loader of your phone. Sony Ericsson can then no longer guarantee the full functionality of your phone, and will not be responsible for any unusable functions or loss of personal data associated to the ROM being flashed to the phone.
