So like many people I'd like to customise my phone with a different imageto the stock. I've done this before with HTC phones, and earlier this year updated to the Xperia Z2, with the intention of flashing it when a stable build came out from Cyanogen.

FInally gotten round to doing this and after a confusing twenty mintues trying to get it into fastboot I learn that on its service page its rooting status, bootloader unlock is not allowed.

I've read that this isn't the case for all Z2s, which must be true else there'd be no builds for it.

What I'd like to know is two things.

1) Why is it not allowed on my particular phone?

2) Is there anything I can do about it?

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Often when the status says No, it's because the phone is locked to an operator. Thereby, the phone have a specific customization which does not allow this. If the status says no, it is not possible to unlock the bootloader.

If I remember correctly, it has something to do with DRM keys which will affect some applications and void the warranty of course.

But why is not possible to unlock. We and all the community want a technical why. Not a simple "not possible" remember that in any way we pay for our phones!!

As I said before, it's often because the operator says no to unlocking the bootloader (a decision made by them). If you want more info why, I suggest that you contact your operator for further information.

So. After finishing contract with the operator and the phone is free. Stills locked ?... There is a code or any way ?? It has to be a way..

It's nothing that will be done automatically and depending on which region your located at, it may be possible. But it's something that you need to ask your operator and/or local support team to see if they are able to give you further assistance in this matter:
