I don't know. But do you have USB debugging on?
Google doesn't say something for your problem? Which tutorial/method you use?
You need root to backup your TA, so yes and no
Strictly seen you don't need it to unlock, but i strongly suggest you do backup your TA do you can restore your drm keys should you ever have the need to

Dude use the SEARCH button.
Watch this:

You don't need to unlock the bootloader to get root. If you wanna keep it locked and get root:

If you do decide to unlock the bootloader. BACKUP YOUR TA:

Yes, before that you have to Backup your TA. Remember, unlocking bootlader will void your warranty.

Root first, backup ta, then unlock the boot.

Okay - is there an all in one guide I can follow from someone? How do I backup the Ta partition and do I have to unlock the bootloader using Android Sdk or is there a different way?

Hey,
I've got a Sony Xperia z1 which I will be selling now and I need to get it to factory settings. Im currently running CM11 and am rooted, unlocked bootloader and have a custom recovery. Are there any guides that will get me back to stock firmware and is it possible to get it back so that no one knows it was ever rooted ?? When I unlocked the bootloader I backed up my TA partition.
Thnx

you can flash the latest official firmware via flashtool(root,recovery gone) than you relock your bootloader and use the TA partition.
good luck

Sorry to bother again but Im a bit of a noob :/ In which order do I proceed then ?? Does flashing the FTF via flashtoolget rid of the custom recovery and root the device ? Then I have to relock the bootloader via flashtool too and then restore the TA partition ???
Flash the FTF, root using newroot, restore your TA, flash the FTF again.
Done

Ohhh and this will regain my warranty correct ??
Well, warranty fraud is not condoned on XDA. I have told you how to relock your bootloader and return your phone to a stock state.
If unlocking your bootloader voided your warranty then its voided no matter what you do after that,

Erhmmm sorry I might be a bit lost ( English isnt my first language...) but I think I get what u are saying... So pls one last question - Is a locked bootloader and stock state any different then when I first got the phone ?
You got your phone with a locked bootloader and stock means it is the firmware that comes from Sony, so yes...
