Hey guys. I'm trying to unlock my booaloader of my Xperia Z C6603.
When I go to the service menu and check it says "Bootloader unlock allowed: No".
The point is, that I haven't bought my phone from a carrier, it's unlocked from factory and I don't know why I can't unlocked it

If it says "No", then it's permanently locked.
Did you purchase it brand new, directly from a store or used from a third party?

Then it's possible that the seller flashed generic software on a carrier supplied phone that they network unlocked before selling it to you.

You should contact Sony support and they should be able to confirm this if you supply your IMEI number.

I contacted Sony and my phone was branded to Three UK, so I can't unlock the bootloader

Sorry to hear that.

Did the seller advertise it as an unbranded phone? Perhaps you can contact eBay to see if something can be done, even if it's some time after purchase. It's worth a try.

You cannot unlock a BL locked phone using flashtool.
If you want a different rom there are plenty of stock based custom roms just use the search function

It 100% won't work. You may soft brick the device, but most probably it will just fail with no adverse effect.
