I don't think it's important to check that option in developer options. It still could be unlocked.
Or simply download the stock firmware for XT1077 and flash it.

Bootloader unlock allowed: No to YES?

Anybody know how to change Bootloader unlock allowed: No to Yes? "My Xperia" security has never been activated, also i flashed another and another ftf file but it's still "No".
Can somebody help me? I would really appreciate it!
Edit: I already backed up DRM keys, is there any chance to unlock bootloader than?

Did you tried a clean flash?
Unlocking bootloader would wipe your phone userdata anyway.

You need fastboot v28 and write it by hand.
Don't copy it from the Sony website.
And please unlock it with PIE .126, so you won't need a camera fix.

Unlock bootloader
Incidentally, I have this problem.
I have a SO-04H.
I tried different ways but to no avail.
I would ask the froum elders to find a solution or trick for this.
