1) download this ftf https://docs.google.com/file/d/0B986eZvi0Z2KZWxQLXhIMmJnWW8/edit ( thanks to @CorePrideX8 )
2) download the flashtool from here http://www.flashtool.net/download.php or https://unrestrict.li/flashtool
3) install the flashtool and navigate to the folder where flashtool was installed
3)open "drivers" folder and install the first 2(flashmode and fastboot)
4)transfer the downloaded ftf to the folder "firmwares"
5)open flashtool and press the thunder button..then choose flashmode
6)you will see the firmware on the left, choose it and press the flash button..wait until a message pop up saying to connect your phone
7)turn the phone off and while pressing the volume down button connect the usb(the illumination bar will light green)

I think your phone will reboot without flashing the firmware because your pc will install the drivers..in order to install it repeat the step 7 :p
Hope it helps..

Im also looking to downgrade my phone from 4.3 to 4.1, I have the FTF and i'm ready to do it, but i was wondering what people recommend for backing up messages and call logs without root? (locked bootloader - can be unlocked but want bravia engine!)

Before updating to 4.3, i took a backup of my apps, call logs, messages...everything in the Sony PC Companion - Backup and Restore program, but once I had updated to 4.3, the backup would not restore properly and apps wouldn't reinstall, is this because of the change in android version? I came from Generic UK .254 for my C5303 and i used the C5303 Central European 1 .266 to upgrade. Im hoping that once i flash the original .254 ftf, the backup will restore properly right?

I just dont want to lose any text messages or call logs, helps me keep track of myself :p

yes, it's the different android version..you will be able to restore with 4.1..next time use titanium backup to backup apps and its data,sms,wifi,call log,bookmarks.

true all my games like real boxing and real steel exit because not enough ram 4.3 update is piece of crap i hope sony will fix all bugs.it's not only the mobile bravia engine 2 but also the walkman and light effects. just download the generic uk firmware found in google drive and flash it using flashtool.

and If Sony published a newer update either 4.4 or anything else, will we be able to install it simply through PC Companion like 4.3 ? or we will have to do other things like those ^flashtool, tft and others ? :D
Thanks :)

if you don't unlock your bootloader you will still be able to install a newer android version via ota or pc companion

    Yes. It's a pain in the buttocks because the apps will suddenly freeze or it won't let me read my texts or answers calls. I'm only concerned about the future upgrade to KitKat or the warranty.
