You will now start to unlock the boot loader of your phone. By doing this you may void the warranty of your phone. Sony can then no longer guarantee the full functionality of your phone, and will not be responsible any malfunctions in your phone, or material damages or personal injuries caused by your phone.
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.
