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.

I have TA backup and locked bootloader.
If I unlock and thereby delete the TA partition, can I then restore the TA partition and still have working DRM functions while keeping the unlocked bootloader ?
No, if you restore TA partition, the bootlloader gets locked again!
Sadly like ulysse34 said

There is no way of keeping an unlocked bootloader with DRM keys active
I unlocked the bootloader, is there any way to restore drm Keys?

You can Re-Lock your device first (just to be safe)
If you used FlashTool to unlock, simply click the unlock bootloader option and make sure the IMEI and unlock code are the same and click Re-Lock
If you did it the Sony way, you should be able to use flash tool
To get back your DRM keys simply go into the TA-Backup program http://forum.xda-developers.com/showthread.php?t=2292598 (script thing) and click on 'Restore'
If you did not make a backup of your TA keys... I am sorry... but you have no way of getting them back

Good News, you can have an unlocked bootloader with DRM functions http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
This thread should help you out, you can have an unlocked bootloader with recovery / root and keep the low light etc functions
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... ?

Is there a way to restore the DRM Keys if my bootloader is locked? I have my TA_backup I did after I unlocked the bootloader and now I reflashed the stock ROM but I forgot to restore my Backup
you lost drm forever, yes, forever.
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?
