Flash tool for Sony Xperia™ devices

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 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.

[How to download and install the flash tool]


The flash tool for Xperia™ is actually called Emma when you install it in this Beta version, and it runs on all Windows computers. This tool is confirmed working for most markets globally*, with a few exceptions** due to distribution restrictions.

To install the flash tool, follow the steps below:
