As the title says, theres a tool that to backup TA partition to save DRM keys before unlocking bootloaders and can restore it back after relock
it's in the xperia z forum but as i know the similar, it might work on our devices. only just someone could test it. i've already backup my ta file using this method but still don't know if it will work after i restore it and may cause hard brick.

give much thanks to rickwyatt for creating this tool :good:
Anyone please inform me the effects of unlocking bootloader. I heard that the camera doesn't functions properly after unlocking bootloader. Can anyone inform me more details about its effects.
youcan do a backup of your TA partition so in this way you will be able to do a complete restore.After unlocking the bootloader the DRM keys will loss.This affects the camera low light performance and the x-reality will stop working.it's a way to get those features work with unlocked bootloader.there it's a tutorial in sony cross development .

I heard that if I restore TA partition then it will relock bootloader. Is it true? Moreover restoring the TA partition can't give the same picture quality as it was before unlocking bootloader. thanks in advance @Anonymuszymus

Restoring the TA partition will restore you to stock ,that's including the bootloader relocking of course .if you do this way the camera will have the same performance as before you unlocked your phone.
But remember if you are not doing the TA partiton backup you will lose drm keys forever!
May I ask..

If I already unlocked my bootloader and my camera lose its proper fucntionality ( auto focus ).. Relocking the bootloader will makes the camera working again ? I dont worry about the DRM or x reality.. just the camera..

Hey all,
I just bought a used Z3+ and was wondering if someone could look at the following screenshot and tell me if my DRM keys are 100% intact and my bootloader has never been unlocked. I'm having a hard time figuring it out because after the first three, all other screenshots I've found have more [Key Ok] [Active] things than mine does. but, they are also for other phones. I'm used to phones without DRM, so I want to make sure I've got everything as intended. Can anyone compare to their Z3+ who may have never unlocked it and see what they think?
Thanks for any help you can provide!
i am 100% sure your DRM key is working
Right now z3+ don't has ROOT without unlock Boot loader
That mean it can't backup TA partition and can't restore DRM key
So this phone NEVER unlock Boot loader.

Got unlocked bootloader without possible root (5.0.2 28.0.A.8.266 firmware E6533 (z3+ Dual)). Used flashtool before unlock and saved S1 Dump in Advanced menu. Is it possible to get DRM keys from S1 Dump and restore bootloader lock?
Or my DRM keys now lost... ?
I want to unlock boot loader but i readed somewhere that after unlocking,phone will lose drm keys and its not possible to restore them
What is drm keys and is it posible to restore phone in factory state(untouched)
Thank you
Yes it possible to restore to factory conditions.
drm are the keys which are used by some sony apps like x reality,video,music ect.
but before unlocking root your phone via kingroot or other then backup ta via backup ta.
Hii. Is there any way to backup the Drm keys which can be successfully restored after unlocking bootloader or rooting the phone? Can anyone point me to that post?
