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..

[Q] Z1 cyanogen 12 (lollipop) on Xperia Z1 bootloader allowed: No ?

Hi XDA!
I just did a straight 7 hours research on how to install cyanogen rom on Xperia Z1, then i saw that we can't on smartphone that is not allowed in the bootloader.
But i saw that we can install with some roms ready for bootloader not allowed. but i didn't find any of the latest version.
And i don't know why we can't toogle it ON... Some websites give their services to toggle it ON. but how they do that ... And no solutions for open public to counter that...
Is there a solution that i miss to pass the bootloader ON ?
Is there a cyanogen mod for xperia Z1 on lollipop for BL ON ?
Is there other solutions ?
Oh and i finally manage to ROOT my Xperia Z1 !
Thanks a lot !
Bootloader
is your bootloader is unlock now ?
Nexus line phones have always had the option to unlock the phone's bootloader. But for all other non-Nexus phone such as our Z1, there are phones with the option:
Code:
[Bootloader Unlock Allowed: Yes], and
[Bootloader Unlock Allowed: No]
There are those firmwares that you can install through a custom recovery such as TWRP on a phone with [Bootloader Unlock Allowed: No] - if I am not mistaken, those firmwares are those that use stock kernels. And those that require a phone with [Bootloader Unlock Allowed: Yes] are almost all of the time require a custom kernel.

Unlock Bootloader

Hello! So i bought my Sony Xperia SP and when i check the service menu Simlock: NO, Bootloader Unlock Allowed:NO.
I read here http://forum.xda-developers.com/xperia-u/general/tutorial-unlock-completely-xperia-t2534127 that when your phone is
simlock: Yes and bootloader: No you cant unlock the bootloader. Is there a solution to unlock my bootloader when its NO to both ?

You cannot unlock the Bootloader if it says "Unlock Bootloader Allowed: No" in your service menu.
And trying any other methods to unlock it will probably brick your device. There are a lot of LB ROMs out there try out. Try them if you want.
Of course i want to change the rom, but for example cm12 has a lot of bugs and the other roms are for UBL. .

There's no recovery available for Jelly Bean (4.3)
Boot into android and dial this and call it: *#*#7378423#*#*
If it says Unlock allowed You can unlock your BL
But If it says Unlock not allowed Your BL is force-locked, and it can't be unlocked

It says "Bootloader unlock allowed: Yes" So I can, but the problem is that I already tried to unlock the bootloader with the official method and flashtool and the first time that I put the code and everything, I get the error "....FAILED in 0.587 s " something like that but if I try twice the second time it seems to worth it, because I get "OKAY in 0.487.. s " for an exemple. But If I really unlock the bootloader why my phone can boot the kernel of Caio? cause I can't, and that is broken my brain xc I want to get the most advantage to this phone and I have to unlock the bootloader for that xD I already give up. I dont know what to do xD I want to try the cyanogenmod rom :c and sorry for my bad english

Bootloader unlock allowed : No

A few days ago i bought myself a secondhand Sony Xperia X Performance....
And at the back it writes AU SOV33 which means japan version of it,but the rom is global version...I tried to unlock my bootloader but i can't...I realised that it shows "Bootloader unlock allowed : No" on the Service menu,is there any way to fix it and make it into "yes"
