For some of the Xperia™ devices, we provide Android™ Open Source Project (AOSP) device configurations on GitHub. This means that the software will be open for you as a developer to use and contribute to. This is a way for us to support the open Android community, and it is also a tool for us to facilitate and verify contributions to AOSP.
Xperia Flash Tool
If you are having issues opening your flash tool, make sure to download the latest version supported by your computer's operating system.
Here you can learn more about Xperia Flash Tool, a desktop application for flashing Sony software on your unlocked Xperia™ device.
This is useful, for example, if you have flashed a custom ROM on your device and want to revert to Sony software. This flash tool only works with Xperia™ devices that have an unlocked bootloader.
Please note that your phone will remain unlocked, and your warranty may still be void.
Only a limited number of phone models and software versions are supported.
