I got a Sony Xperia Z1. It's currently running 4.4.4 but I want to downgrade to 4.3. I don't know how to do this and that's why am asking here. I've tried googling for a solution but have yet to find anything of the sort.
Modelnumber: D5503
Version: 14.4.A.0.108
Androidversion:4.4.4

Haha....just kidding..
Well, download 4.3 and flash it through flashtool.
I remember we were losing IMEI if we downgrade from 4.4.2 to 4.2 so check for that...
I think there's method (ftf) to avoid that..
Search for NUT instructions...

There are millions of tutorials here...
You have to downgrade to 534 firmware, root it and flash NUT ROM and stripped ftf (or any other stock based ROM)
Latest firmwares can't be rooted directly, that's wht you have to be on "current rooted" firmware

Any FTF ending in 534 for your phone model will be ok
Hello guys. Anyone knows how to downgrade my Xperia Z? I've upgrade it to Kitkat 4.4.2. But it seems that 4.1.2 is better for Xperia Z. Kitkat 4.4.2 is quite lag. Specially on HD Games. Please help me guys. Thanks!

Just flash the 4.1.2 firmware? No other things to do before flashing?

OP's issue is solved.
Downgrade your Phone to Jélly Bean
To do that, simply check, if you are able to do that, first.
You can do that by typing the Telephone Number „*#*#7378423#*#*"
Then tap on „Service Information" and go to the Configuration.
After that you've got to go to unlockbootloader[dot]sonymobile[Dot]com to get your Unblock-ID, also-called Unlock-Key.
Accept the terms and Confirm, if you're REALLY SURE!

Bootloader unlock is not required to flash stock rom.
Xperia Z shipped with Jellybean so he has to download jellybean FTF and flash it using flash tool.
As I have posted above the issue is already solved.
The procedure you have mentioned is required for flashing CUSTOM roms
