Entering Fastboot mode
Power off the device. Hold  as you plug the USB cable into the device.

Bootloader unlocking
The process of unlocking the bootloader officially is available here and it is strictly adviced to use it in the first place. It has all the instructions for one to unlock it.

 * The above methods are "s1tool" and will not get around "Bootloader unlock allowed: No". There doesn't seem to be a way to get around "Bootloader unlock allowed: No" except for a software+hardware box combination called SETool2 that can be used to modify any Sony Ericsson device. This is what likely what has referred to as a "paid unlock" - rendeko

What works

 * Building and installing to external SD card
 * Display
 * Touchscreen
 * USB networking
 * Xwayland

What does not work

 * Plasma Mobile
 * Hardware accelerated graphics
 * Audio
 * Bluetooth
 * GPS
 * Camera

Note that Wi-Fi and osk-sdl are untested and may require further work.

Additional info

 * Page size may need to be adjusted in the future, as it is non-standard and presents a non-fatal error.

Links

 * The kernel currently being used
 * Xperia Flashtool that should probably work once it is unlocked. With source code!
 * there's possibly also a 3.10 branch in the wild
