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).

Hi guys,
I got a used Xperia Z1 that came rooted but with stock rom. That said, I have no way to know if the owner previously installed other stuff on it.
I mainly want to make sure that BIONZ (the camera engine) still works fine and enhances my images. I currently have .257 installed and the camera works fine. AFAIK the bootloader is locked - I manage to back up TA so that means it was there to be backed up.
Still, I'm not sure whether or not this BIONZ thing is working. I wanna be sure I'm getting the max quality out of my camera. Any idea how I can test it, toggle it?
If the bootloader unlock the camera simply won't work, ao if it do work you are fine.

I will ask also here, because I will get my Z1 soon. If I unlock DRM keys are deleted, so Camera stops, I can put back the keys correct? But does the camera still doesn´t work under CM for excample?`(Even after Sony fixes the DRM problem, if ever..)

hopefully sony will fix camera for unlocked bootloaders otherwise we are all stuck with sony stock rom for eternity...
or at least they whould realese some app that allows our camera to work even with unlocked bootloader..
Ok, than my guess was right, we are stucked with Sony rom, sad...
Edit: Forever, DRM reading software is not possible under CM (it would violate there license) only way would be an export import of the APPS and software needed? Anyone looked into that?
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:
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
Quite some time since we had good root fith camera partition backup. Xz premium, xz1, ... didnt have one. I think this one should. So please if anyone has time, it would be superb!
Unlock bootloader, flash twrp, magisk and that's it for root.
You can forget about drm backup and drm fix depends if sToRm// feel like it I guess.
Unless there's someone else out there that will get the XZ2 and can make a drm fix.
