OK, I have done alot of reading and have a question for someone with more knowledge than me. Where are the DRM keys at that get deleted when you unlock? I noticed when looking at system files there is a DRM apk. Is this something to do with it? Is it possible to copy/backup this before unlocking?

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

just wann know about which to down load and the manual more specific>>>> confuseddddd
Any one can help me?
I haven't checked XDA in awhile because I gave up hope of ever having a good root solution for the Z5. But I have been looking around lately and have seen roms such as [ROM][E6653] Slim Stock 32.0.A.6.200 and the [LP][UB][ROOT][DRM][KERNEL][RECOVERY](TWRP3.0) Z5 ADV STOCK KERNEL (2016/03/04) (v1g) kernel. So as of now, I'm a little lost here. Of the 15+ Android phones I've had, this has been the most complicated.
I understand that root is possible by unlooking the bootloader and that as of now, there is no root solution for a locked bootloader. Are you now able to unlock the bootloader and root with phone without losing any features?
You still lose DRM. There is a possibility to trick the phone into thinking the DRM keys aren't wiped restoring the DRM features after unlocking the bootloader but the DRM is still missing.

So you'll lose DRM keys but you can still retain all the features? I hope the same will be true for the Marshmallow update.
That's right. We don't have a kernel to run modified system images on MM just yet so can't confirm nor deny it working.
Just as mentioned above. I dont mind waiting but just wanna ask is there anybody able to get it already? I've done some google, some pages offer a very 'detailed' instructions like just install TWRP using fastboot method then flash the SuperSU binary then bingo!! Some others state unlocking BL is required. Since to me xda is the only reliable source so I guess I will be looking for answers here.
Cheers
since the Z3+ and newer devices, root with lock bootloader is impossible at least for now.
btw, unlock bootloader is so easy for root, why not? Warranty?

Well... DRM keys thing is what i concern. AFAIK im gonna have to give up some features if i lose it so...
Btw it'd be appreciated if u could share some posts about re-locking bootloader and backing up/restoring DRM keys, especially for this new Xperia XZ.

I've been waiting for over 3mths for some progress on backing up the ta keys on all the x range(I have the xa) I don't see it ever happening to be honest and I've made the mistake of loosing ta keys before I won't be doing it again.

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
Hello,
Since i am new to rooting on a Sony device , i tried it downgrade to lollipop in order to backup the keys all is fine.
I am now back to stock, since i cannot understand some things.
I want only a stock root rom, but i want to keep the drm in place or simulate it in some way i dont wanna lose some funcionality of the phone is that possible?
Since i read things about drm fix etc.
Can someone explain what is possible with Sony and rooting with emulate or replace drm after root.
btw sorry for my bad english.
Just flash patched stock kernel with drm fix and you are good to go. btw check for it in Xperia Z5 Premium forum, not here.
