If you recently updated your Xperia firmware to Android 4.0 Ice Cream Sandwich and was wondering about root access then we’ve got some great news for you. A root toolkit has been released that will work for those on both locked and unlocked bootloaders. The toolkit will install Busybox (1.18.4) and SuperUser files.
The process itself is simple and involves downloading a file, extracting it using WinRAR and then clicking on ‘RUNME.bat’. It should work on all 2011 Xperia handsets running the official ICS update. See below for the full instructions.
Instructions to Root the Android 4.0 ICS Xperia update
Preparation
– You must be running 4.1.A.0.562 firmware on your Xperia.
– All necessary drivers need to be installed on your PC (including ADB drivers). If you have any problems you will find the necessary drivers once you have installed Flashtool in the following location: ‘C:\Flashtool\drivers’. See our previous post on this for the download link.
1) Download the Rooting Toolkit
Download the ‘Rooting Toolkit for Xperia 2011 ICS’ from this xda-developers post. Extract the contents to a folder on your PC.
2) Switch on USB debugging on your handset
Switch on the debugging option on your Xperia. Go to Menu –> Settings –> Developer options –>Tick ‘USB debugging’
Also tick ‘Unknown sources’ under Menu –> Settings –> Security
3) Connect phone to PC
Switch your phone on and connect it to your PC/laptop via USB.
4) Run the Toolkit
Now double click the ‘runme.bat’ file from the extracted files from step 1.
The messages will tell you that the phone needs rebooting and will do this several times – do not panic!
5) Your Xperia handset running ICS is now rooted
After a while, you will see an “All Done” message. Congratulations your phone is now rooted.
