Many users sometimes face the issue of flashing their smartphone or Sony tablet Xperia and have difficulty because they do not know how this process is done. I want to say right away that it is best to use the standard programs that you can find on our website in the section. With their help, you can automatically and without any problems update the kernel and firmware versions to the most up-to-date and current at the moment.
However, there are times when the installation still has to be done manually. V this manual we have outlined all the steps point by point, in order 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 proceeding with 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 at least 50% charged, that Flashtool and firmware drivers are already installed on your computer, and antivirus programs and firewalls are disabled on your PC to be sure.
1. And so, let's get started. To get started, download official firmware, the package of which will be in .ftf format. Download firmware only from trusted sources and only for your phone version.
2. If the firmware is loaded with a simple archive, then unzip it and find a file with the .ftf extension there.
3. This file must be placed in the / flashtool / firmwares folder.
4. Run FlashTool.exe.
5. Turn off the smartphone and wait about 30-60 seconds.
6. In the program, press the button on which lightning is depicted. Next, select “Flashmode” and double-click on required firmware or simply drag it into the window from the utility.
7. The program will independently prepare the firmware for its installation on a smartphone, about which you will be notified by the appearance of a window asking you to connect the device.
8. Hold down the volume key down (aka Volume -) and connect USB cable(which should already be connected to the PC) to your smartphone. It is possible that the first time you connect in the “Flashmode” mode, a window will appear asking you to install the driver for the device to work in this very mode.
