Xperia Z Bootloader unlock issues help

Howsit Guys
Need a lil help here. Im currently on firmware- 10.4.1.B.0.101 with [Root & XZDR] http://forum.xda-developers.com/showthread.php?t=2643898 <-- via this method.. all Works sweetly.. Problem is that i want to unlock my bootloader. Ive checked in the service menu, unlocked bootloader is allowed.
I am currently trying to unlock bootloader with latest version of Flashtools(unofficial way).whilst phone is on, i connect cable, startup flashtools, it detects device. Then i click on lightningbolt icon, to unlock bootloader. menu comes up asking to remove cable, power off phone n goto flashmode.
When i get to the part where it asks to select my device, i click on xperia z. And i get a FAIL message saying i cannot officially unlock bootloader?? Do i need to be on stock .244 firmware or stock kernal to unlock ? Or am i going through it the wrong way. main reason i want unlock bootloader to install cyanagen mod11 nightly.
Thnx

Done
Sorry for the silly post.. managed to unlock my bootloader..

The easier way would be manually downloading 4.4.2 ftf and flash it using flashtool
download ftf from here
download flashtool from here
Make a backup before flashing ftf though as it will wipe the internal memory

[Q] Xperia Z1 root problem. Please help

Hello dear members,
my xperia Z1 is running on 4.4.4 build 14.4.A.0.108, I was looking for a method to root it.
I understood that I have to unlock the bootloader before rooting. The problem is that the phone says bootloader unlock says NO when i enter the "*#*#7378423#*#*" menu...
Is there a solution to root the phone without unlocking the bootloader or a method to unlock the bootloader even if not allowed?
Thank youuuuuuu all

You do NOT have to unlock the bootloader to root
You do HAVE to look in the development section for the root tools though
Just google "root xperia Z1 4.4.4"

Thanksss !

[Q] RE-UNLOCKING Bootloader

Hey friends, I have a Sony Xperia Z device. First, i unlocked it's bootloader, then i re-locked it using the TA-partition backup. But now I want to RE-UNLOCK the bootloader to install the new Android 5.0 and I don't know how to do it. Do i need to do it in the normal way?

hello I also have an xperia with the bootloader blocked that can not be unlocked.
What you have to do is to downgrade with flashtool looking for the software of your model, after you have already done the downgrade you can root with kingoroot for desktop and you can install the recovery I recommend the dual here they say how to do it.
if you are looking for a rom here there are some for bootloader blocked greetings.
