Hi guys!
My Xperia Z Ultra is on the 4.4.2 firmware, but I want to go back to the 4.3.. Can I go back without unlocking the bootloader? Does it work just flash the 4.3 firmware or do I have to unlock the BL?

Thanks.

You can flash 4.3 using flashtool. You don't need an unlocked bootloader. However, you may have to check "wipe data" for this to work.
