With the new android version update the tablet is going to look all the more attractive and interactive. The android 4.2.2 has many enhancing features like a very good user interface with soft touch buttons. The new update is also bringing the notification panel with quick settings.


    • If you wish to install the Android 4.2.2 in your tablet manually you could do that by following the below guidelines.
    • Before starting with such process it is always recommended that you have to charge your phone fully. Make sure the battery is 100% or at the least 60% charged. Backup your data as such process may lead to data lose or use CWM or TWRP if you have it.
    • Make sure Sony USB drivers are installed on your computer. If you have PC Companion installed on your system, USB drivers will be there already.
    • If you dont have the PC Companion, you can download the same from here.
    • Enable USB debugging mode on the tablet. You would find this in the applications settings of the tablet. (Check under development).
    • If you have rooted the tablet or running any Custom ROM, note that this firmware installation will remove the same.
    • Connect the tablet with pc via USB. The Sony companion would detect the tablet once the device is connected.
    • Choose the firmware upgrade option in the companion and further check in T&C and start upgrade.
    • The download starts and installation will begin in some time.
    • Once done the device would run upgrade and reboot.


    After rebooting you can check the android and baseband version in about tablet options in settings of the tablet. Check if your tablet has been updated with the android 4.2.2 JB. It should be done by now.

    There is also an alternate way of updating Sony Xperia Smartphones and Tablet PC. It is infact a better and dedicated way of updating the Firmware for your Sony smartphones and Tablet. Simply download Sony Update Service, also known as SUS. Installation takes about 2 minutes. Once installed, connect the phone via USB Cable, select your Model from the list in SUS, and click OK.

    SUS will detect your phone and offer you two options, whether you just want to update the software OR you want to repair and update the software. If you have any problems with the device then select the second option or Simply select the first one and move ahead. Click Start and move away from PC. SUS will download, install the firmware and reboot the device on its own. You dont need to do anything. After reboot, configure the settings and check About Device option at the bottom of Settings. It should be running on the latest available software for your device model.
