The question comes to my mind,because of the following reasons :
1) Bravia Engine not working (flashed xreality zip by @xperiaz2 but still no success)
2) Gracenote not working

But the catch is,that the "issues" I'm facing are in the replacement device(refurbished) that SONY gave me recently for the dead pixel issue :-/

I went in the service menu and it shows bootloader unlock allowed: yes :P

I even backed up TA partition of this device but it's of much lesser size than of my original device

The only thing that I could think of right now that I might have done wrong here is that, as I got my replacement, I restored the entire TWRP backup (system,data,,,) which I had taken in my original device,without noticing the BRAVIA ENGINE in album

So I wanted to know that whether my bootloader was ever unlocked by someone earlier, and that I've lost my drm keys??
Should I return this device to them?

Please guys,help me on this one!

You can check the status of your DRM keys in the service menu.
Enter *#*#7378423#*#* in the dialler then look in Service tests - Security. All the keys should say [Key OK][Active].

Bootloader unlock allowed = yes, means bootloader is still locked and unlockable.

It could have been unlocked before and relocked and it would still say that though. That's why I posted the method to check whether the DRM keys are intact or not.

I don't know, possibly something to do with restoring a backup from another device. If DRM keys are intact, BE2 should work. Try flashing a stock rom with Flashtool and see if it works then.
