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://forum.xda-developers.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.

1.1 Dial *#*#7378423#*#*
1.2 Select service info and then Software info. Your customization number will be display for example 1264-3189/R3E.

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

2.1 You can find the different customization numbers in this post:

3. Create a backup of your build.prop file

3.1 Using your root explorer go to file path /system/
3.2 Select the file build.prop and create a copy of it and save it in another location.

4. Edit your build.prop file

4.1 Edit your build.prop file and replace all the places where your current customization is display with the desired customization number:

##### Final patch of properties #####
ro.build.product=LT22i
ro.build.description=LT22i-user 4.0.4 6.1.B.0.544 371_zw test-keys

ro.product.brand=SEMC
ro.product.name=LT22i_1262-0972
ro.product.device=LT22i
ro.build.tags=release-keys
ro.build.fingerprint=SEMC/LT22i_1262-0972/LT22i:4.0.4/6.1.B.0.544/371_zw:user/release-keys

######################## Customized property values #########################

ro.semc.version.cust=1262-0972
ro.semc.version.cust_revision=R6G

4.2 Be sure that you replace all the instances where your customization is with the one from the firmware you want.
4.3 Save the file and close it.

5. Reboot your phone.

6. Verify the new customization number.

6.1 Dial *#*#7378423#*#* and verify that the phone displays the proper customization number for the firmware you want.

7. Use Sony Update Service to restore your phone.

8. Once the Software is restored you will be running the customized firmware from the selected region.
