will bravia engine work with this?

i was on 6.2.b.1.96 xs 4.1.2 rooted
then i took TA Backup.
now today i unlocked bootloader for the first tym (DRM keys preserverd in TA backup.)

now if i restore my TA backup while the bootloader unlocked, then will it restore drm keys and will bravia engine work?
m nt trying it because m afraid of bricking the phone.( just recovered from a soft brick yesterday). has anyone tried?

yes surely mate ...go ahead with restore....it will restore ur DRM keys and bravia engine will work as it was at the time of backup...

when u restore ur TA BACKUP it will restore ur DRM keys and bravia engine & ur BOOTLOADERS will get locked again....u have to unlock it again for custom kernel flashing...
so just flash stock firmware first on which u had taken TA backup and then restore it.... if you're using a custom kernel, you'll brick the phone.......so u must be on stock firmware first before restoration process...hope this helps...

Just to add since you just recovered from a soft brick.

If you restored your TA while using a custom kernel, you will hardbrick your phone which I believe is unrecoverable...
