Root Sony Xperia S on Official Ice Cream Sandwich Firmware

A few hours back we published a tutorial which lets you update your Sony Xperia S to the latest official Ice Cream Sandwich firmware. In the previous post, we also mentioned about the features of the official ICS firmware. I’m sure you would have liked them but there are some system apps which Sony introduces in the official firmwares which they release which may be called as “bloatware”. This is because you may not wish to use them and they also occupy a lot of internal memory on your phone. Such apps run in the background and also consume RAM memory degrading the performance of the device.

To get rid of bloatware, you need to remove system apps introduced by Sony and hence you need to root your phone as removing system apps is not possible without rooting.

There are many other advantages of rooting which can be known by reading a post of mine on BlogoTech.

In this tutorial, we will tell you how to root the Stock Ice Cream Sandwich firmware running on your Sony Xperia S LT26i.

Backup Data & Prerequisites

The few points listed below will help you backup your data on Sony Xperia S. It is very unlikely that you will lose data while rooting but it is always a good idea to backup before you proceed with any hacking activity on your device.

  • Back up all apps using ASTRO File Manager. You can get the APK files using ASTRO and later restore it.
  • Back up all contacts to SD card.
  • Backup SMS on Android.
  • Backup call log on Android.
  • Make sure you have the recommended drivers installed.
  • Have minimum 60% charge on your phone else you might get stuck while the update process is running on your device.

Procedure to Root Sony Xperia S on Official ICS 61.A.0.452 Firmware

  1. You need to have Android SDK and Platform tools installed on your Computer.
  2. Download Nazomi Recovery Image and Super User to your computer.
  3. Place the recovery image in the “Tools” or “Platform Tools’ folder depending on where you have ADB.exe file.
  4. Download the Kernel and place it in your device’s SD card. Also, place the Superuser zip into the SD card.
  5. Open Command Prompt in the Platform Tools folder. This can be done by navigating to the folder and pressing “Left Shift + Right Mouse Click” on Windows and selecting the option “Open Command Prompt here”.
  6. Connect your phone to the computer via USB Cable and type the following command in Command Prompt:
    adb devices
  7. This should return a list of devices attached with a serial number. If you get an error like “ADB command not found”, then you have not installed Android SDK properly and if it shows “no devices attached” it is an issue with the device drivers on your computer.
  8. After you see the device serial number, type the following command in Command Prompt:
    fastboot flash boot recovery-nozomi.img
  9. Now you can boot your device into recovery mode by typing:
    adb reboot recovery
  10. Flash the Suepruser and Kernel from the SD card in recovery mode.
  11. Open the FTF file with 7Zip or similar compress-program and extract kernel.sin and flash it using the command:
    fastboot flash boot kernel.sin

This will root your Sony Xperia S on official ICS firmware. If you face any issues, head over to the original thread.
