This is a small tutorial on how to get any customization firmware directly from Sony. It should work on any Xperia, I already tested it in a Xperia P and a Xperia neo.
Requirements:
1. Locked bootloader.
2. Root (Get root with locked bootloader http://xdaforums.com/showthread.php?t=1886460)
3. Root explorer like ES File Explorer
Process:
1. Identify the customization on your phone, depending of the phone the customization number is in back below the battery, other phones like the Xperia P use the service menu.

2. Find the customization number for the firmware you want to install.
