It seems a lot of users are unaware of the "Emma" software by Sony. It provides us with the opportunity to flash stock firmwares of any customization on Xperias with unlocked bootloader. Many of you must be knowing that PC Companion and SUS cannot be used to install official updates on devices with unlocked bootloader. Well Emma is here for help.
Please read all the instructions before proceeding.
Presently it's in Beta stage and supports a limited number of Xperia phones Check the List of supported phones
Note: If you did not place the the Customization.ini file in the correct EMMA folder ( steps 3,4,5) then you won't be able to use it as it would ask you for username and password. So kindly follow the steps correctly.
How to Flash using Emma

Remember : The first time you start your device after you have flashed it, the boot-up might take a little longer than normal.

This thread was locked and don't know how come it's open again.
Both of you make sure you're following the steps correctly.
Have you pasted the customization file in the correct place ? without that you can't even run emma.
Phone should be connected in flashmode. Without that , Emma won't recognize a thing.
Please post further in this thread

I just downloaded the package and can confirm that it has the Customization.ini file in it.
Kindly redownload this http://developer.sonymobile.com/downloads/tool/flash-tool-for-xperia-devices/
After that extract the zip file using any software you have and then you will have the customization.ini file as well as emma setup.
