Hi there!
I've unblocked my BL (z5 premium dual) but I forgot to backup DRM keys. Are they still intact ? Are the lost? In that case....would it be possible to recover them? thanks!
Then your DRM key is lost forever, the only thing to get it back (for free) that's you have to make something to kill your device's mainboard, then send it to service and you would get DRM back with the new mainboard.
Thanks.

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

i saw that problem, and try to resstore the functions only, i found the topic http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672 but confuse how to do with my device ( 6616) with the risk of brick(((((
just wann know about which to down load and the manual more specific>>>> confuseddddd
Any one can help me?
Are my DRM keys intact?Look at the attachment at the bottom
No, they aren't.
No. Fido keys are missing
Ur drm keys are lost when you unlocked the bootloader, i don't think u did TA backup before unlocking cause it wasn't possible that time.
I have not received the 32.2.A.0.305 update for my Z5 yet, so I went to XperiFirm to check which region my device's firmware is from. It turns out the firmware is CDA 1298-2996 (South Africa).
I live in Australia and wish to flash the Customized AU firmware with CDA 1298-7277. I want to do this so that my device will be updated and will be using the Australian firmware.
My bootloader is locked; is flashing possible without unlocking the bootloader?
Will flashing a different firmware potentially cause damage (my device is not network locked, and single sim E6653).
Will this affect my warranty / DRM keys?
Thank you in advance, I appreciate any help :angel:
You are safe to flash almost any E6653 Firmware onto your E6653
Obviously dont flash test firmwares or ones that May lock your sim

Thank you And the DRM keys should not be affected? I have read that unlocking the bootloader only affects the keys.

you can flash and what ever with your device, DRM keys are safe!
when u ulock bootloader, the device WIPE user Data and sony partitions (TA (trimArea) partitions) and DRM keys and FIDO keys will be lost!
this $h!t is with sony only!!
i rooted my fone and having modified kernel having DRM stimulation installed. its working fine now.
- at any given day, to a thirsty user who wants to CONTROL his Xperia to the most. i would say, ignore drm keys and make a deal with devil to have root access
- however since Xperia Z5 (unlike latest xperia Xseries) came out on LP kernel. so u can FLASH LP kernel and root it with app like kingroot and extract your DRM keys to windows pc and back it up. now u can flash the LASTED Android back on you Xperiaz5 and unlock your boot loader to have root access.

Thanks for the advice, I will look into it in the future when CyanogenMod improves and I need to unlock the bootloader to install it. My main incentive for this would be to greatly improve the camera, which we all know takes very washed-out photos.
I have just gone through the firmware flashing process. Thankfully there are many guides available and it all worked just fine, so I am using the current, correct firmware now
The worst part was just the waiting and suspense (feels like a lot could go wrong).
Thanks again Envious_Data and YasuHamed!

i had flashed Cm13 on XperiaZ and inbuilt camera app of CM13 was worse than xperia! and if you think you z5 camera isn't working properly then God Help you when you won't have DRM keys in place! because the DRM keys actually enables feature of camera which wont be activated if DRM keys are lost
nothing will go wrong! be confident! sony devices are Hardcore stallions! once you nail them! they will be your pet!
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
