[Q] some questions about drm keys etc - Xperia Z3 Compact Q&A, Help & Troubleshooting

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:

[Q] Bought used Z1. How to verify BIONZ works?

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?

[Q] X-reality/image enhancement stuff disappear in options

Recently updated to stock lollipop (when i have unlocked bootloader)
Maybe once i forgot to flash the drm feature restore file, then the X-reality in display options disappear x_x
(I though even u unlocked the BL it will stay as an option just not functional??)
Anyway as the stock lollipop is problematic I try rockZ1L (great rom thanks to venkat)
I think this rom is supposed to show bravia3/X-reality/supervivid options right?? still isnt shown in display options
I tried to relock with TA then, still no luck :'(
Thx for help

Off. update/DRM keys

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.

[Q] Unlocked BL, relocked BL - haven't lost DRM?

Hello everyone!
Some time ago I became bored of slow stock firmware and decided to install CM11, following my good experience with Sony LWW. I unlocked BL via fastboot on ubuntu (making no backups. I will learn someday...), then installed CM11 using CM's instructions for Xperia SP. I've got a working phone, it worked for two months, but was not as fast as I thought, and in addition to that it gave me frequent all-system ANRs with a reboot, when I browsed large pages in firefox. So i decided to go back to stock.
I downloaded a stock firmware called "C5303_12.1.A.1.205_РСТ" and flashed my phone using Flashboot. Rebooted and got a working phone. Then I relocked a bootloader, rebooted again, and again got a working phone. What's more interesting, all features which need DRM still work, i.e. Bravia, Walkman information downloading, TrackID (used to break after flashing back in time).
So I have some questions. Does that mean that I've got a fully stock phone with all features and DRM's somehow? Can I check that? Do I need to worry about DRM anyway?

But how is it still working then? I just finished downloading info on my music collection, and bravia seems to work... I don't understand what I did wrong to get it working perfectly.

some users even showed us the x-reality engine with UBL...so it could be working normally in some way ...so i don't know how is that could be possible ...but maybe you are lucky ....try to backup your DRM keys see if the exists (that is impossible but try it,, you won't lose anything ) :silly:
can not find camera app in menue
Hi,
I have flashed build 06/26 (dirty). Sometimes I can not find the camera - app in menue.
Under settings -> app -> activ app I can find the camera app (is installed) but I can not start them. In menue I doesn't find the app.
Has somebody the same problem?
Sorry for this "survival" englisch and I hope everybody know what I mean

Yup, does not allow me to make a backup. "Backup" and "Restore" options are grayed out in Flashtool, and only "S1 dump" is available. I assume DRM keys are gone. But as long as the features are working, I won't care. I will surely make a backup of everything before doing something to a phone next time. Thanks for an answer.
wenfosi, you may have either:
1) changed the way menu is presented. Swipe from left side of the screen in menu, and select "show apps by alphabet"; or
2) accidentally disabled the Camera app. Locate it in Settings - Apps, click on it, and look if there is a button called "Enable". It should be at the top, near the "Force stop" button. If it is there, then click on it. It will change to "Disable".
Maybe more experienced users will provide more advices. Try these at first.

Have you tried another camera app from the Play Store? This information helps to find the error.
By the way, your English is OK. Is it possible that you are German?

Z1 X-Reallity, BionZ on unlocked bootloader

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
