Yes it can! its no problem because drm keys are stored deep and secure at your BIOS.
It will automatically lock the unlocked bootloader also.
Hit thanks if this helped you!

Hi, is it any tutorial about locking bootloader an restoring TA.img?As I know to restore TA i beed to do smthing like
dd if=/sdcard/TA.img of=/dev/block/mmcblk0p1
How to lock bootloader?
Did you use the backup tool by DevShaft? If yes you can restore TA with that tool again.
If not I don't know... Maybe you can search in the Z forum, there you will find many instructions that also work on ZL. Good luck!

How did you restore TA without bricking your device?

Some backup utility or dd worked for me. I don't remember much of the details though.
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...
recommend to do this on stock firmware on which u had taken the TA backup....Hope this helps...

but dont it look weird, unlocked bootloader and drm keys working together? i didnt read anything like that on internet. can u quote any such link?
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...

Can you please explain the reason behind it?
Hi, I believe that I have returned my phone back to stock.
But I'm frankly not sure if the phone is still rooted, and if the boot loader has been relocked.
I did use the TA Backup program to restore my DRM keys.
Then I simply used Flashtool to flash the latest ROM .108 onto my Z1C.
Will my phone be accepted for warranty repair?

If you did this you are ok for warranty.No need to worry...
Thanks! I appreciate the reassurance.
so the TA isn't related to stock rom version? or in other words, it isn't important if you backed up the TA while running 757 rom, it's okay to restore TA and flash 108 for exanole?

just to be sure,.. restore TA on the version you made it from..
my 2 cents
HI guys, i am interested into installing CM11 on my Xperia S , and i have backed up my TA and stored them on my PC.This procedure though, requires unlocked bootloader. In case i want to revert my phone back to locked( stock ) status, what do i have to do? I mean, how will i flash this TA backup? in a locked or an unlocked status? and via fastboot with Flashtool?

You save your TA via? Flashtool or some script? Use the same program as you use to backup. If ftool - probably flash it via ft.

Before i flash the restore file i have to be on stock Sony Fireware? And what must my bootlader status be like? Locked or unlocked?
Best idea its be on stock.
but why u ask about bootl? Now You have unlocked ;p So You must have unlocked? For restoring = re-lock it?

why do u want to relock? do u have DRM KEYS/TA.IMG backed up somewhere in your pc ? to restore?
anways
with flashtool you can relock it and then unlock it again!
keep the original unlock key with you (just in case) or you can always ask sony for the keys

if the bootloader has been unlocked it can never be fully restored. you can never lock the bootloader the way sony did.
All you can do is to wipe and flash untouched stockrom and sell it
for flashing use flashtool / fastboot modes. you can do google for tutorial. its easy.
What about drm?

if you never took backup of your DRM then they are lost too! if you have taken backup then restore them manual. but whenever the buyer flash the device the keys will be lost too.
I have backed them up with TA backup

then relock your bootloader and sell it off. if the new owner don't change anything then the keys will stay intact.
however, if you could guide the new owner about it and email them the keys also , it will be fair deal
because you cannot use these keys on any other device.
Should I lock the bootloader first or restore TA first?
Anyone?
Answer: restoring TA automatically locks Bootloader.
But it needs root, so first restoring TA then flashing stock ROM with Flashtool.
