    Many users sometimes face the question of flashing their Sony Xperia smartphone or tablet and experience difficulties because they do not know how this process is done. I want to say right away that it is best to use standard programs, which you can find on our website in the section. With their help, you can automatically and without any problems update the kernel and firmware version to the most current and current one at the moment.

    However, there are times when the installation still has to be done manually. In this guide, we outlined all the steps point by point to make it easier for you to understand how to flash a Sony Xperia. This manual is suitable for 2013 models and you will need the Flashtool program, which can be downloaded from the link below. Before you begin any action, remember that the author of the article is not responsible for the final result and everything you do is at your own peril and risk. Also make sure that the smartphone is charged at least 50%, that the Flashtool package and firmware drivers are already installed on your computer, and for greater confidence, anti-virus programs and firewalls are disabled on your PC.

    1. So, let's get started. First, download the official firmware, the package of which will be in .ftf format. Download firmware only from trusted sources and only for the version of your phone.

    2. If the firmware is downloaded as a simple archive, then unzip it and find a file there with the extension .ftf.

    3. This file must be placed in the /flashtool/firmwares folder.

    4. Launch FlashTool.exe.

    5. Turn off the smartphone and wait about 30-60 seconds.

    6. In the program, press the button that shows lightning. Next, select “Flashmode” and double-click on the desired firmware or simply drag it into the window from the utility.


    7. The program will independently prepare the firmware for installation on your smartphone, about which you will be notified by the appearance of a window asking you to connect the device.

    8. Press the Volume down key (aka Volume -) and connect the USB cable (which should already be connected to the PC) to your smartphone. There is a possibility that the first time you connect in “Flashmode” mode, a window will appear asking you to install a driver to operate the device in this very mode.
