I had the same problem. couldnt install via wifi or data connection.
as some other friends in this forum said, I tried to update my device using PC Companion program and it worked!
there was just one problem. at the start of update download, windows firewall prevent PC Companion to reach the internet. you should unblock it.
now, I have android 4.4.4
I will post my experience with kit kat 4.4.4
Iran, Xperia ZR

Hi! I have a MAJOR problem. Colud not install latest upgrade on my ZR using the phone, so today I tried using PC Companion...
The download of the files went on fine and instlalation on the phone began - now I get a message on the phone on a black screen that the installation failed - try again - AND I CANNOT RESTART MY PHONE!! Further the PC will not register that the phone i connected - so NO CONTACT with th ephone at all!!!!! PLEASE HELP!
Is it possible to boot the phone somehow manually ??

Try performing a system repair - This will factory reset your phone
Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the onscreen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process
If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP

Hi Thommo, thabk for the quick reply - just tried with holding volume + power button - but still got the screen with "Software update failed... Try again"

The volume up plus power is to fully switch your phone off before peforming a system repair - Did you follow the rest of the guide - Also is your bootloader unlocked or are you rooted?
