How do I go about unlocking my boot-loader? I tried using flash tool, but it says my Xperia Z is not supported for unlocking?!

I did a clean install on my device..rooted...installed cwm..and now I need to unlock boot-loader, but I have no idea how to go about doing this successfully...and help or leads would be great! Thanks!

If Bootloader unlock allowed says Yes, then you can continue with the next step. If it says No, or if the status is missing, your device cannot be unlocked.
Now what?!

The answer is in the post you quoted. If it says "No", then you can't unlock your bootloader. There's no way around it.

EDIT: I see some post when researching stating that other users where in my situation and then it changed to yes somehow..

If you want to spend time trying to bypass it, then that's up to you. It 100% cannot be done. Nobody has broken the bootloader security on a Sony device since around 2011.
