Step 1. Download the above any one of them Android ICS firmware package FTF zipped file into your PC. Extract the zip file by using by either using 7zip or winrar software. After extracting, you will get the LT26i_6.1.A.0.452.ftf and file size will be like 345 MB.

2. After that, you need to download the FlashTool into your PC from here, which is necessary to flash the firmware on your Xperia S device.

3. Install the Flashtool software in PC. Then go to C Drive and open the flashtool folder. There you can see drivers folder. Double click the flashtool-drivers.exe and select the Xperia S in the device list. Click install the compatible usb drivers for your Xperia S.

4. Now Copy the downloaded LT26i_6.1.A.0.452.ftf file into C:/flashtool/firmware. Before copying the ftf file, delete all existing files in the firmware folder. Make sure that only our current ftf package will be in the firmware folder.

  23. In order to solve WiFi tethering you must install third party application called FoxFi (WiFi Tether w/o Root) download it from Google Play Store. It will instantly activate the WiFi tethering option and share the internet with others.
