How to Download and install
Follow the instructions below to download and install the beta 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 you can’t upgrade to this build number, it is not possible to try the Ice Cream Sandwich beta ROM for Xperia™ phones.
- Go to unlockbootloader.sonymobile.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.
- Download the Ice Cream Sandwich beta ROM for Xperia™ arc S, the Ice Cream Sandwich beta ROM for Xperia™ neo V or the Ice Cream Sandwich beta ROM for Xperia™ ray depending on your phone model.
- Extract the downloaded zip file to your Android Fastboot directory. For example: ..\android-sdk\fastboot\Xperia_arcS_ICS_beta.
- Open a command prompt and go to your Fastboot directory: ..\android-sdk\fastboot\
- Flash the three beta 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_beta\boot.img
• fastboot flash userdata ..\Fastboot\Xperia_arcS_ICS_beta\userdata.img
• fastboot flash system ..\Fastboot\Xperia_arcS_ICS_beta\system.img
- Once done, please reboot your phone.
