Sony Xperia S was launched at the beginning of this year at CES 2012 and it came with Android 2.3 Gingerbread, but Supervenom, an XDA Senior Member managed to create a port of the popular AOKP ROM for Sony Xperia S that allows users to flash and install Android 4.0.4 ICS AOKP custom ROM firmware.

This new ROM can only be installed on rooted Xperia S devices. Do not attempt to install SuperVenom's AOKP based ROM on any other smartphones as it won't work. You should know that this build is currently in its alpha state and this means that it still packs some errors that should be fixed in future releases. Remember that this guide should be applied only by advanced Android users.

Before we can start installing the new ROM on your Xperia S you will need to read some guidelines and learn how to properly prepare your device for the firmware update. Here's what you need to know:

  • It is recommended for you to create backups of all the important files currently stored on your Sony Xperia S phone.
