Unlock Bootloader: No (any way around this?) - Xperia Z3 Compact General

There are lots of posts out there like this that provide instructions on how to unlock the bootloader, and many other posts that say you can't if Service Settings reports "Unlock Bootloader: No". My problem is that my phone reports 'No' and I very much want to flash a custom rom. Can I do this by downgrading the firmware or some other process? Apparently, Sony won't do this remotely... Help!?

UPDATE:
Here is my transcript from Sony support:
My phone reports Unlock Bootloader: No in System Settings.
Andres M

If it says No, or if the status is missing, your device cannot be unlocked.
In this case I recommend you to contact to a third party technician in order to unlocked.

Is this true? Can 3rd party services unlock bootloaders? If so, how do they do it?

Sorry for a tangent question.
The guide linked by OP is for ALE-L23 model, but would it work for ALE-L21? If that is unlikely, are there any guides for ALE-L21?
Finally, other than the model number, what else is important to match-up when trying to install custom roms?

what link?
very important -> model number (ale-l21 must be ale-l21 and not ale-l02 because they have another chipset)
important but fixable -> location (c432 must be c432 and not c034 (making things up))
also important but fixable -> dual sim and single sim
something to take into consideration -> android version
so if you have the next version ale-l21c432b564 don't flash ale-l02c69b049 over it

My phone is ALE-L23C605B140, so all sorts of different from what I see in those guides. Is it possible for me to downgrade/upgrade to a version that's compatible first, or do I just need to wait for a guide that works specifically for my phone?
My phone is also dual sim, and running Android 5.0.1 if that helps.
