1) Firmware is the Android system itself, so bootloader will be unlocked.
2) I don't know Sony Xperia U, but in HTC devices there is a text label "Locked" or "Unlocked" in newer bootloaders.
3) You have to unlock the bootloader only once. Flashing roms doesn't affect the bootloader itself.

[Q] Not booting after re-unlocking bootloader

Hello.
I was in a custom rom and it was 4.04 ICM (I don't remember which one) and I already had an unlocked bootloader (which I couldn't remember) and I tried to re-unlock it
Now on my phone the Sony Ericsson logo re-appeared and it won't boot (it was Sony with my custom rom)
I used this method for unlocking bootloader

I have this CWM

Now what should I do?
Should I flash stock firmware?
Should I flash another custom?

You relocked bootloader, right?
Or did you unlock it again?!
Anyways, if you did a relock, you must flash a stock ftf and/or a ROM for a locked bootloader.
Because, your custom kernel based ROM won't run on a locked bootloader.

Bootloader unlocked for custom recovery?

Could someone clarify this for me:
Is it true that in order to install a custom recovery the XTZ needs to have its bootloader unlocked?
I installed custom recovery on my XZ phone alright without having to unlock the bootloader....
