Hi everyone,
My warranty just expired on my z3c so I am thinking about trying aosp on my phone. I've read that you can restore your DRM key after unlocking BL, which will restore functions such as x-reality, etc. But I haven't seen anyone mention restoring camera quality. My question is, will restoring DRM key restore ALL lost functions due to BL unlock, including the camera quality? thanks
PS. if anyone has any input on stock vs AOSP performance, that would be appreciated too.
You wont lose any function if you do the backup and restore. I sugest you to try first the slim 4.5 rom (no need to unlock BL).

Hi all,
id like to put a question; since i have a Sony device for my first time, i didnt knew about camera quality decreasing and Sony services halting with bootloader unlocking. Im very up to taking photos, and camera quality is very important for me, X-Reality too. So, since i lost my DRM keys, when i flash official ftf file, then ill lock my bootloader, and then update my FW from KK to Lollipop by official way via Software Update - will it recover my DRM keys?

Sorry but once you lost the DRM keys (without backing them up) they are gone. Have you tried this "fix", it emulates a couple of functions that you lost, http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
---------- EDIT -------------
Actually I saw that you posted in that thread already yesterday saying that the patch worked - good for you!

is it possible to backup drm keys after i lost them? i managed to backup TA-backup-20150*****.zip several days ago (but im not sure if before/after unlocking bootloader.
EDIT: well i did saw some incerasing camera quality, but x-reality didint worked. im trying to solve my issue, but it will take a long trip. how Cyanogenmod camera holding up?
If you take a backup of nothing - you still have nothing when you restore it.
If you unlocked before backing up - that's it - nothing you do on your own is going to get the keys back. Only Sony can restore keys, and likely the only way they will do that is by replacing the mother board and charging you the parts and labor for it.
If that's not an option for you - then the DRM restore is currently the only other path to follow.
hi guys, recently I unlocked my BL to try some custom roms then came back to stock, relocked BL, and restore my backup TA (did the backup before unlocking so I got back my drm keys I think).
I think the drm keys were restored properly, because for example in album I see images with improved colours when x-reality or super-vivid options are enabled, while in other apps images look a little worse.
strange thing is that by default in settings > display the image enhancements are disabled, so at the beginning, also in album, images didn't look improved.
after enabling x-reality or super vivid options, images look better. problem is that after each reboot, the image enhancement is again set to disabled! and I have to always enable x-reality or super-vivid manually!
do you know why? I don't remember this happening before unlocking the BL, so don't think it is because of my debloated FW. is this really related to unlocking the BL? or something went wrong when relocking BL/restoring keys?
how can I check if I really have all the drm keys enabled again?
and when I take pictures with the camera, will the image enhancement alghoritms be always enabled? or after each reboot first I should do something to enable them?
thanks in advance guys hope you can help me in clarifying this!
EDIT: seems I fixed the problem clean installing again my debloated fw! :good:
problem is back again... don't know exactly what is the problem.... for sure it is not the debloat, so maybe some apps I installed? so strange!
nobody else has this problem? you never see "disabled" in display > image enhancements settings? :silly:
Hi. Can anybody help me? I unlocked my Z3C and i forgot to make a TA backup. I found some DRM fix, but not working. I tested on stock KK, stock LP, and now i have stock MM. V3 fix not working. I tested all DRM fix and didn't worked.

You have to do a factory reset first and after that flash DRM fix. DRM fix won't work until you wipe /data partition.

That's the correct procedure. Do the wipes and then flash DRM fix, it has to work. How did you check if it works? Noise reduction works only on 8mp even with your TA keys (same is with DRM fix) so that's the resolution on which you need to check.

I checked on 8mp and 20mp. very much noise
Once UNLOCKING your bootloader you LOOSE your DRM keys FOREVER, most DRM fixes only get your sound DRM functions
Once you have lost your DRM keys, your camera will stay noisy etc, currently there is no Camera DRM fix

No it won't stay noisy forever. DRM fix works as it should. I have my TA keys backed up and bootloader unlocked. I have tested camera with TA keys restored and with UBL with DRM fix applied, everything is same. One thing that people don't know is that noise reduction works on 8mp ONLY, even with original TA keys. That's just the way it's implemented. However I do not have explanation why it won't work for OP, I have successfully applied DRM fix more than 10 times probably, on all android versions available (KK, LP, MM, even on concept).
I would like to know is there any way to get back X-reallity and BionZ after bootloader unlock. I know the solution wich save DRM keys before the unlock but when I did it I didn't know about it and about I will lost this features. So I found Bravia restore solution for X-Reallity. But after I installed and did everthing what was in the install section, I dont see any differences. And the BionZ. I have stock .236 rom and Im using Adaptive display mod and for my cam I installed the Z5 premium libs. So about the pictures, I dont feel it same as it was before unlock.
I need your help guys is there any way how I can chack this feature working or not and other way for X-Reallity getting back?
Sorry for my bad english.
If you don't have a TA backup from your phone, you have lost the proprietary Sony algorithms that make pictures appear better on your screen. It is not the camera apps or libs, but rather these algorithms that matter. And they are not recoverable, even if you relock your bootloader...
So i will never get these things back?
Not on this phone...
Not true, you can have these stuffs with fake drm keys: http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
I'll try it
Hi,
So I've tried every tutorial that has been published out there in regards to restoring the DRM functions on my Xperia Z3+ (Single Sim version) but to no avail.
I tried the method posted by najoor https://forum.xda-developers.com/xperia-z4/general/guide-safe-bootloader-unlock-restore-t3386915 followed every step (Managed to back up my DRM keys, unlocked bootloader successfully). I then flashed a stock Marshmallow rom that was posted on the thread by wolfaas12345 https://forum.xda-developers.com/xperia-z4/general/nougat-firmware-z3-e6553-6533-t3545481 (I flashed the 32.1.A.1.185 one that's posted there).
Then I followed the instructions to emulate the DRM keys as posted in the najoor thread (2- How to emulate DRM keys and/or root and/or add recovery after unlocking the bootloader.). It looks like everything seems to be working (I'm able to go to Recovery etc). But then when I go check to see my DRM functions, they aren't restored. (Camera is still emitting lots of noise, x-reality isn't added back). I double check it by going into Service Mode by dialing *#*#7378423#*#* then into Service Tests -> Security and still see the errors there.
I gave up using this method eventually, then found out another thread posted by jimRnor https://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672 that has a drmrestore zip file for xperia z3+. I flash it using TWRP recovery and it looked like it was flashed successfully, yet when I go check whether the DRM functions are restored, they aren't.
I'm at a loss here now. I don't know where am I going wrong or what step am I doing wrong. I would greatly appreciate any help here if someone can guide me to the correct steps to restoring my DRM functions on my phone.
Thanks!
