So i read that restoring the DRM keys using Backup-TA will relock the bootloader if it was unlocked.
And unlocking the bootloaded deletes them again.
So just for confirmation: Is it not possible to have restored DRM keys and an unlocked bootloader?
Following that: Can i unlock the bootloader, flash a custom Rom, restore the DRM keys and have a custom rom + the camera algorithms? (and a locked bootloader)

No but most AOSP ROMs have now the camera as is in stock so there shouldn't be a difference,but as for stock ROM there is a DRM fix you can flash just search it up on XDA.

Hi!
We know that backing up TA with locked bootloader saves DRM keys. I`m not too bothered about this as I have TA backup.
However...
If I create another copy of the TA partition once I have unlocked the bootloader (I know the DRM keys will be gone) but would it enable me to switch between locked and unlocked bootloader states just by restoring the appropriate backup?
So...
TA Backup #1 - Locked bootloader with DRM intact
TA Backup #2 - Unlocked bootloader with DRM gone
Could I just use Backup-TA to switch between both backups and unlock / relock bootloader as I wish? Or does it have to be unlocked via command line every time?
Many thanks for your input.

Good man. Thanks.
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
Hello!
I currently backed up my TA Partition and DRM Keys using Backup_TA.bat, I now have an Unlocked Bootloader and also am running on a custom kernel ( FW .232 Lollipop ), my question is if I use the restore function on the Backup_TA.bat will that re-lock my bootloader?
Thanks alot!

Yes it will relock BUT
You need to be on an official firmware and rooted. And you must have the stock kernel. Then only you can restore. If your restore TA, it relocks bootloader. And custom kernels don't work on locked bootloader so you will end up in a bootloop if you are not using the stock kernel

Btw, do you another way of relocking the bootloader besides using Flashtool?
i try using restore in backup_TA but my bootloader its still unlocked
im on stock rom and kernel + root, in flashtool i dont have option to relock :/
Restoring TA is supposed to relock bootloader automatically aa far as I know :/
Hi to everyone i need tutorial for how to relock bootloader and restore DRM key (i have previously backuped it). Actually my z3c run 6.0.1 stock ROM. thx
after 3.5 years, i'm currently looking for the same thing
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.
