You cannot use the TA Backup of another phone to re-lock your bootloader (To restore "Bravia Engine 2" or "Download Music Info" functionality. Each phone has a different set of DRM Keys embedded in the TA partition. Using the TA Backup of another Xperia SP will hard brick your Xperia SP.
Just my 2 cents.
