Backup Your TA Partition Before You Unlock Your Bootloader



please read this

This wont work if you Unlocked your bootloader already because
you have already changed you TA partition. also don't flash
someone elses TA it will hard brick your phone




what i found out

I backed up my TA partition before unlocking my bootloader
after unlocking my bootloader with flash tools and lost my drm keys and ba2
so i thought to myself what would happen if i flashed my locked TA image
i then reflashed it with adb and rebooted my sony z was
locked and drm and ba2 was working again it was like i never unlocked it sweet


heres a video as proof

if it was that simple I think that dev would have already did it, plus Sony secure its stuff harder than that.

You can check in service menu under service tests if DRM Keys are intact.
