1.Download and install Flashtool on your PC.
2.Download the firmware you need (from the list below) and move it into the directory C:/Flashtool/firmwares
3.Open Flashtool, click on the lightning symbol ("flash device"), select "Flashmode" and click on "OK"
4.Just select the name of what you downloaded and click on "Flash"
5.Wait for a window to pop up (it may take a few minutes, be patient)
6.Now everything is ready: turn off your phone
7.Push the volume-down button, keep pushing and connect to your PC
8.Once the flashing process has started, release the volume rocker as soon as possible
9.NEVER disconnect the USB cable until it's finished!!!
10.Turn on and enjoy!

IMPORTANT:
if you are using Windows 8 you will need to enable few things to allow driver installation
If you are a Windows 8.1 user, you must see this video

Default Phone will not switch on ...

Tried unlocking the boootloader following instructions from the Sony website,
after "sucessfully" unlocking the bootloader in flashboot mode the phone got stuck in a boot loop.
Eventually stopped the phone boot looping by pressing all the buttons at the same time, have now found out it is the two volume buttons and the power button, then the phone did not switch on at all, tried connecting and holding volume button etc, to USB but all that comes up in device manager is "unknown device" and the flash tool does not recognise it in any mode, found out that holding the power button down for five minutes reboots the phone. Then flashed with above firmware and ended up in another bootloop, holding the up volume and power button makes the phone vibrate once then three times, let go after one and then you can get into flashmode, this time I flashed the latest firmware from http://forum.xda-developers.com/show....php?t=2762296 and it worked.
