sorry for my bad english
you cannot restore any drm keys that did not come from the device initially as you will brick the phone, sounds like you bought the phone 2nd hand and the person unlocked the bootloader, unless you have a copy of the drm keys that were backed up before the bootloader was unlocked then you have lost the drm keys

Hi all
I have a rooted Z3. On the paper DRM keys should be untouched but I am not impressed with the camera's quality.
I flashed pre rooted rom and subsequent rom updates but wonder if something didn't go wrong along the way.
So, simple question : how can I test the effective presence of DRM keys / make sure the functions that come with it are present on my Z3?
Thx

Your DRM keys will be totally intact unless you unlocked the bootloader.
Are you sure? I thought that flashing a full 'home made' pre rooted rom could over right TA partition resulting in useless drm keys... Isn't there some part of the rom that has to be exclude to prevent just that ?

Do you see any difference in camera before and after installing preroot rom?
Having an awesome camera doesn't means awesome photo. There is many other things that makes a photo great.
Composition, subject, correct use of modes or manual settings, white balance...
I for one is not impressed with the stock Sony camera. But granted its much easier and better than other phone cameras available. I'm impressed with its low light capability, speed of autofocus, and all those amazing preprogrammed modes.
I'm no fan of manual control. If I need manual control, I'll need raw as well and for that I bought a dslr..
This Sony camera serves what I need. Quick, Good, camera to catch things at the right time.

Which version Z3 you have and which pre-rooted rom did you flash? The only version that has a locked bootloader is the T-Mobile Variant. And like all the other members stated, you can only lose DRM keys if you unlocked the bootloader. If your bootloader is locked then DRM will be retained even if you rooted and flash a pre-rooted rom.
I have a D6603 with current stock rom pre rooted. BL is locked.
Regards to camera (and not my photos) i am disappointed. I find the white balance dull/approximate, low light noisy and the overall sharpness quite bad. Hence I wondered if it was due to some messing about with drm keys...

To truly check open the phone dialer and type *#*#7378423#*#* then navigate to "Service Test" then "Security". If the first three lines says MARLIN [Key OK][Active], CKB [Key OK][Active], WIDEVINE [Key OK][Active] then your drm keys are intact, if it says unknown then the drm keys are gone.
All OK active under security test, so I guess I am fine.
Thanks
I have Z3 T-Mobile carrier (D6616) from my friend but "Bootloader unlock allowed: Yes" but key "unknown error"
Code:
MARLIN [unknown error][Active]
CKB [unknown error][Active]
WIDEVINE [unknown error][Active]
However, I can manage to download music info from SONY. What happened with my device DRM Keys?

This means that you are able to unlock the bootloader but that it is currently locked.
Unless the bootloader has been unlocked the DRM keys are intact
Your DRM keys are intact.

Many THX. I feel it uncommon because D6616 bootloader is told that cannot be unlockable and the keys has "unknown error".

Hello everyone,
I'm here cause I'm going from a z3 Bl unlocked, custorm ROM and other to an z5 bl unlocked cause gived by a sony employee who repair phone.
But he give me it with an unlocked bootloader, then I don't have the DRM.
I don't want to make some bad things like with my z3 who have some freeze, reboot or other things.
The z5 is in 6.0, is it possible to get back the DRM to get back fingerprints and all other stuff like photo treatment,.... ?
Also, there is a operator rom with just some apps installed that I desinstalled, is it going wrong with next maj or not?
Thanks for your answers
Edit: I think that this unallow me to cast with a chrome cast?
IF the previous owner backuped the TA partition/DRM keys before unlocking the bootloader, it's possible he still have these backups in his possession OR possible he restored the TA partition after installation a custom ROM, TWRP, rooting, etc.
If you can, open the dialer and type *#*#7378423#*#*, then go to "Services tests" -> "Security"
You should see two [Active] occurences, OTP_LOCK_STATUS: LOCKED / FIDO_KEYS: Provisioned
That means the DRM keys are active and that's what you want. If it's the case, I would strongly suggest you to temporarely downgrade the phone to an older Lollipop firmware and backup them in a safe place (thre's many guides on this forum)
Personally, I wouldn't buy a second-hand Z5 that doesn't have its DRM keys intact anymore, or at least a proper backup of these keys.
I thinks it's good I have this :
Marlin key ok active
Widevine key ok active
Ckb key ok active
Huk:...
Prodid_aid:0004
Otp lock config 0155
Otp lock status locked
Auth enable 07
Device id:...
Fido keys provisioned
Factory reset reason : not found
Then I have just to find a tuto who downgrade and backup drm?
Edit: I just pay a new screen cause he was broken and old owner give it to me ^^

Seems that all DRM keys are intact, you may follow these instructions to backup your TA partition :
http://forum.xda-developers.com/cros...-tool-t3349597
Try to flash stock firmware and perform wipe on it so you could test all are working normally.
Thanks redjge,
But after put a Sim card into the phone everythings seem okay
Ok sorry for idiotic question, but what are DRM and why do i need them? i backed them up on start before rooting, now i have tested few roms and stuff. But do i need to restore DRM for better photos or something? Or os not possible to restore DRM on costum rom. Its my first sony in years
I don't know that much on DRM and Development, I'm just a passionate guy, so what am gonna say is perhaps wrong so dont blame me
DRM (Digital Right Management) are keys used to "protect" the phone.
Those keys are sets by the firm (In this case SONY)
To enable some functions on the phone.
When you buy a new phone, DRM are already set up and everything works fine, but some phone functions require those keys to work (on the Z5 x-realty photos, bravia engine display needs them to work) .
If you unlock your bootloader, you delete by the same time those key located on the TA partition and so, X reality and Bravia cease to work,
I know that on the Samsung devices the fingerprint sensor is completely disabled if you lost DRM I don't know if it's the same on the Z5.
Once deleted you can't recover them, they're lost for ever, even if you relock your bootloader !
Actually I don't know if you can recover the keys if you have backed up your TA partition, but according to what I've read you can't, BUT you can emulate them.
DRM aren't only for phone, you can find some in video games protections, computer, or that kind of stuff
So is missing bravia noticable on phone?
Actually I can't answer, I'm waiting for a locked bootloader root in order to keep the originals DRM.
Guess you should ask someone who has unlocked his bootloader and lost DRM to see if there are some noticeable changes?
I don't see a big difference regarding X-Reality, but where there's a big difference is in the photos taken without the DRM keys.
If you want to root your phone and keep the DRM keys, read this: http://twigstechtips.blogspot.ch/2016/04/sony-z5-compact-root-without-losing-ta.html?m=1
I'm currently trying to get the TA partition restored on a stock non-rooted ROM
Ivory flaw is only available on lollipop?
I'm f*cked then I'm running Marshmallow and I don't want to flash a new Rom wiping everything :crying:
Thanks but I'll try later if there no root for Locked BL on Marshmallow

keep me posted, i have TA partition backuped, it would be nice if i could restore DRM keys and use stock rom
So do HTC devices also have DRM keys in the TA (trim area) partition that must be backed up before unlocking the bootloader ?
Similar to Sony devices? Thanks for the answer.

DRM keys in Sony Xperia smartphones are located in the TA (trim area) partition of the phone.
When unlocking the bootloader, the TA partition gets erased and you lose your phone's unique DRM keys forever unless you backed it up first.
Without the DRM keys you lose a lot of special functionality such as special camera features like BionZ, built-in noise-cancelling, X-Reality engine, Bravia engine, Track ID, Miracast etc...

Are you 100% sure about that? On HTCDev bootloader unlock website it says:
Some content on your device may also be invalidated and cannot be accessed any more because of invalid DRM security keys. This includes content that you may have purchased through a 3rd party vendor and through HTC. Furthermore, although you will still be able to receive updates to your device via FOTA (“firmware over the air”), we do not guarantee that updating your device via FOTA will not render your device unusable. Please understand that you will not be able to return your device to the original state and going forward your device may not be held covered under the warranty for all claims resulting from the unlocking of the bootloader. HTC bears no responsibility if your device is no longer usable afterwards.

HTC devices might have the DRM keys and that partition, but when unlocking you won't lose anything, so you're good to go with unlocking BL and do custom stuff
