Based on a community request, we created a simple instructional video showing how to download and install the flash tool (EMMA). Watch the video here to learn more about Sony’s Open Device program.
The instructional video is a new and updated guide on how to download and install the flash tool needed to flash supported Xperia devices. The flash tool is commonly known as EMMA, and is a desktop application. Please note that the flash tool can only be used with devices that have an unlocked boot loader (you can find a list of the devices here). The flash tool enables you to flash your unlocked phone with standard Sony software. Note: When you flash software onto your device, your user data and content will be erased. Make sure to properly back up all information.
