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:

1. Download the Flash tool for Xperia devices.
2. Unzip the file you downloaded and place it somewhere on your computer.
3. In the unzipped folder, run Emma.exe. During the installation, make sure you remember the installation path:
   1. Default path in Windows 64 bit is: “C:Program Files (x86)Sony MobileEmma”
   2. Default path in Windows 32 bit is: “C:Program FilesSony MobileEmma”
4. Copy the Customization.ini file. You find it in the Flash_tool_for_Xperia_X.zip.
5. Paste the Customization.ini file into the installation folder. The installation folder is the folder named Emma in the installation path examples on point 3.1 and 3.2 above.
6. Click Start > All programs > Sony Mobile > Emma (if you used the default installation path from step 3 above) to start the flash tool
