Here you can learn more about the flash tool for Xperia™ devices, which is a desktop application that you can use to flash Sony software on your unlocked Xperia™ device. This is useful if you’ve for example flashed a custom ROM on your device, and want to go change to a standard Sony software. This flash tool can only be used by Xperia™ devices having an unlocked boot loader. Please note that your phone still stays unlocked, and that the warranty may still be voided.
Also note that only a limited number of phone models and software versions are supported by this tool, as we are currently running it as a beta version.
Follow the instructions on the Install page below to download and install the flash tool. Flash instructions and a list of supported phones (including flash key mappings) are also found in the pages below.
