Thanks a lot for the feedback! I will update the OP accordingly. As for the BIONZ Engine, basically just check to see if 12800 ISO and other different SCN modes are working.
[Xperia Z3 Compact General] istux:
Yes, just tested and they're all working fine :good:

About audio quality and powerness, I guess there's a difference between z3 and z3 compact, as the first one is known to have a better audio than the second one.

Maybe the difference is only software related and the unlocking just breaks the magic??? If this were true, then an unlocked z3 would sound like a z3 compact...

Anybody tried this supposed fix?

[Xperia Z3 Compact General] istux:
Very very interesting, I will give it a try for sure, but only when I see some positive feedbacks, as playing with DRM keys can be very dangerous (for example you can get a hard brick if you try to restore DRM keys which are not yours).

How this mod is supposed to work? Does it just reactivate all the features or does it put DRM keys inside your phone? :confused:

Let's see... ;)
[Xperia Z3 Compact General] gabsi55:
I HOPE this works :)
[Xperia Z3 Compact General] stemilano:
Ok, but I can become root without bootloader unlock? I'm not interested in third parties rom at the moment....and this should not hit all reported missing features
[Xperia Z3 Compact General] istux:
You can't at the moment. This is the point :(
[Xperia Z3 Compact General] perlmane:
I would prefer to get the quality back than to have root.
[Xperia Z3 Compact General] istux:
So, do you want to test THIS before me? ;)

You just need a deodexed stock rom, I've seen one within the development section...
[Xperia Z3 Compact General] perlmane:
Nope. I got in this trouble because I was among the first to unlock before the issues were posted.
[Xperia Z3 Compact General] cflow:
Is there any way to get rid of the camera shutter sound without root? I'm in Japan (legally required) so there's absolutely no way to turn it off via settings. For my Galaxy S3, I went into the directory and deleted the sound files, but I'm assuming this requires root.
[Xperia Z3 Compact General] tocirah1:
Try flashing a ROM from a different region. It should have the option in the camera.
[Xperia Z3 Compact General] charliebigpot:
Has anyone tried this?

http://xdaforums.com/showthread.php?t=2292598
[Xperia Z3 Compact General] tocirah1:
Yes. The tool does not work without root.
[Xperia Z3 Compact General] charliebigpot:
Ok, so I guess this is still the most likely option at the moment:
[Xperia Z3 Compact General] Iruwen:
It doesn't restore the DRM keys because that's impossible. Judging by its contents, my guess would be that it somehow modifies the DRM system so it always reports that DRM is functional. Only seems to work for some functions, but if you only want the camera algorithms back, that could be the way to go. I'm quite sure that this won't make things like Miracast work again and naming it "DRM Restore" is very misleading since that's obviously not what it does.
[Xperia Z3 Compact General] gabsi55:
Did you apply the .zip and then did the factory reset?

I think this is the way you have to go... Would be interesting
[Xperia Z3 Compact General] istux:
Yes I did.

Anyway now I'm deodexing by myself as I don't know if the patch I found in developement section worked properly. Then I will try again the mod and the factory reset ;)
[Xperia Z3 Compact General] gabsi55:
Too bad. :(

Would have been nice if it was only this mistake ;)
[Xperia Z3 Compact General] istux:
No way.

Tried with a new deodexing and a new installation of the mod + factory reset.

It does not work.

I give up and retry if the mod will be updated...
[Xperia Z3 Compact General] Sean09:
Are you sure it is not just failing to work due to root? It won't work on rooted devices unless you hide root or remove root. EDIT - referring to PS4 Remote Play.
[Xperia Z3 Compact General] GoldPunch:
It worked on my Z2! Thanks a lot

Camera algorithm problem is solved.

Miracast is still not working.

Noice-cancelling problem is solved.

these work on my BL-unlocked Z3 compact!
[Xperia Z3 Compact General] istux:
Thanks!

I'm pretty sure that with z3

compact

the WHOLE audio stuff keeps on working properly also after unlocking. :good:

In fact, I didn't hear any change even with sound quality and powerness. Do you confirm?
[Xperia Z3 Compact General] ilbefun:
a little better when low-quality music with HSEE:)
[Xperia Z3 Compact General] graffixnyc:
The only reason why I haven't unlocked is for the camera degrade and the noise cancellation.. If it's been confirmed that that method fixes those two things then I'll be unlocking. All the other crap I don't care about
[Xperia Z3 Compact General] rob rich:
me too
[Xperia Z3 Compact General] istux:
2 people tried that mod on z3 compact (me and another guy) and it doesn't work.

It seems to work properly on normal z1 , z2 and zr with only some specific firmwares.

The main problem is the lack of communication with the author of the mod, as the OP on XDA is not the same person.

If someone can speak chinese, here is the original thread: http://bbs.gfan.com/android-7715822-1-1.html

About the camera, I can't see degrade in general, but only in very low-light conditions (in this case if you use flash, the pictures are perfect anyway).

Yesterday I made a lot of pictures (manual, 8mp, no hdr) like THIS ONE (you can watch the bike and also read what is written on the paper) or THIS ONE ...and I never had issues in any light condition (even if there were many lights, it wasn't easy at all to avoid underexposures and overexposures). :good:

I also tried Google camera with hdr ON and 20,7 mb like THIS ONE and everything OK :victory:
[Xperia Z3 Compact General] Pyres:
without any reference shot, those pictures are not very significative per se....
[Xperia Z3 Compact General] vittogol:
How do I know if it was unlocked?

I have just bought a used Z3 Compact. I noticed bad camera results so I read about this DRM loss gate.

So I'm doubting that my device was bootloader unlocked and then relocked from the person who sold it to me.

Please explain me how can I check if it was locked and then relocked and I have lost the DRM.

Testing configurazion it says bootloader allowed: yes

I don't see on off differences between Super-Vivid, X-Reality but Movies unlimited loads and see movies preview.

So I don't know what to think.
[Xperia Z3 Compact General] Dsteppa:
Well just try to root your phone and you'll know.

When you unlock your bootloader your phone will also be wiped, so I guess that's the best way to know if it worked or not:P
[Xperia Z3 Compact General] charliebigpot:
No need to trying to root right away ;)

If the previous owner unlocked and than relocked the boot loader the DMR keys will be gone for good, you can check here:

Go to the dialer and dial: *#*#7378423#*#* then go to "Service Tests" - "Security". If all keys are ok your boot loader was not unlocked by the previous owner.

Good luck!
[Xperia Z3 Compact General] vittogol:
I don't want to make things worse. Brick or some other bad things I read some parts of the procedure.

If there is some other way more easy please let me know. thanks
[Xperia Z3 Compact General] charliebigpot:
Read what i just posted ;) This is only a check and nothing happens to the phone:

Go to the dialer and dial: *#*#7378423#*#* then go to "Service Tests" - "Security". If all keys are ok your boot loader was not unlocked by the previous owner.
[Xperia Z3 Compact General] vittogol:
Thank you so much! This was an easy test to do. I got [Key OK][Active] for all the key items.

So the verdict is that my Z3 compact take bad pictures (even worse compared with my old Galaxy S2) in high contrast situations (I tryed all Manual superior ecc. configurations).

It keep overexposing pictures, washing out colors most noticable on sky with cloud shoots.

Comparing it with my Iphone 6 it's a very very disappointing camera device. It get overclassed in all situations.

Last: the 2 options Super-Vivid and X-Reality don't do anything too, at least for me and my wife sight.

Still have a litte doubt. Sure the test you suggest me prove that it has not lost the DRM?
[Xperia Z3 Compact General] boojay:
Yeah, it's unfortunate, but it had already been established that "Inferior" Auto mode on this phone is pretty awful.

If you switch to Manual mode though, photos are MUCH better. I have mine set to multi-metering and touch focus in manual settings, while keeping the ISO as low as possible, depending on the situation, and pictures look great.
[Xperia Z3 Compact General] vittogol:
Yes you can make things it better in the manual mode. I tryed all settings but I can't reach the results I get from an S2 in auto mode. Believe me. Only resolution is better if you zoom.

This is very disappointing. Also the display colors and brightness is worse than S2. I have balanced the white in the setting but if I put both devices on the table and compare them watching with a 45 degrees view the Z3 compact turn evidently to bluish and less brightness.

So we have bought this device to change from an S2 that is 4 year older but we get:

- worse camera pictures (over exposing, slow auto focus, bluish washed out colors)

- worse display brightness and color balacing (same size display in most situation because of the onscreen buttons) and depth of colors gamma.

- no root without loosing DRM and issues

- I hope battery life is better because it seems in the morning after some pic taken and surfing to go quick down to 84% to last the same as S2 with its bigger changed battery.

I'm considering to sell the Z3 compact and get back to the S2 at this point because it's price is not worthwhile.
[Xperia Z3 Compact General] wooki:
I think I'm soon going to bite the apple and going to root next weekend.. I don't want to wait any longer even when loosing the keys will make the overall phone worse.. I don't think android 5 will change anything to good if I wait or?

[MENTION=6223730]vittogol[/MENTION]

Have a look at the Xiaomi mi2 (not the mi2s) it has a very good camera, has decent hardware and its cheap. It's display isn't bad but even worse than the z3 ones.

It has a very good batterylife (and there's and extented battery) and together with cm11 you get good performance :D

[Xperia Z3 Compact General] King p1n:
Highly doubt the s2 produces better photos.
[Xperia Z3 Compact General] BlueScreenJunky:
I had to restart my Galaxy S2 after reading your comments just to make sure... Well on mine (and in my opinion) both the screen and camera are better on the Z3 compact.

The screen is a little sharper due to the higher resolution, can be A LOT brighter, and doesn't have that blue tint the S2 has. It does get darker when looked at from an angle but the S2 gets even more blueish.

The camera (used "Superior Auto" on the Z3c and Auto on the S2) also produced slightly sharper pictures, and brighter pictures in low light situations.

It's not a huge improvement though : the SGS2 was an awesome phone (and a $600+ one) just 3 years ago, and it's still a pretty solid phone today, so if you don't need the new features of the Z3c (4G LTE, bluetooth 4, aptX, wifi AC, NFC...) or the performance boost, then you may indeed be better off keeping the SGS2 a while longer and see what's coming next.
[Xperia Z3 Compact General] vittogol:
Today I made some shoots comparison between my secondary phone a LG G2 mini and the Z3C.

Absolute winner was the G2 Mini.

Better contrast. Sharpness and color fidelity.

Shooting at Skys white clouds take some color while on G2 are perfect brilliant.

I tried manual superior auto and every possible configuration (ISO auto on off exposure resolution ecc...)

I discovered that the only trick to choose fast the exposure you have only this way:

Move and pan the screen until you find the wanted exposure (you can't do that with touch like on other phones) then press the 2 way down camera button and hold it at the first step down. Then move again the phone to choose what you want to shoot and press all way down.

This way I can get iphone g2 and s2 same exposure effect but not as good as them.

The button can make you take pic a little blurry even if you try staying perfect steady.

Anyway on low and high dynamic range pictures there's something wrong on the software compression. When you zoom and compare the pics details you can see more artifacts, noise, loss of white and redness and less sharpness.

Sorry for my English.

Allegedly, someone has made progress in restoring DRM lost features to the Z3 Compact, albeit the D5833 model, at least the Image Enhancement Bravia Engine anyway:

Good luck man! /fingers crossed
[Xperia Z3 Compact General] boojay:
Here are the steps he used to restore DRM lost functions to the Z3 D6653 (and possibly Z3C D5833?):

If the latest firmware doesn't work, he did previously report that he was able to successfully do so with an older firmware on the D5833.

If anyone with an unlocked bootloader Z3C D5803 wants to give it a shot, please do so and report back.
[Xperia Z3 Compact General] marumari:
Why does it require the crazy lock/unlock dance? Does reflashing a stock firmware restore the DRM keys, when on a locked bootloader? Can you not just flash it to an existing .77 system that's running AndroPlusKernel v12?
[Xperia Z3 Compact General] boojay:
No clue dude, just the messenger. This guy is the only one to have reported any kind of success with the Z3 series so far, so I thought I'd spread the news and hopefully others can repeat the same kind of success following his exact steps.
[Xperia Z3 Compact General] boojay:
Update: A couple more Z3 Compact users have confirmed it's working. One even said it was for the D5803!

This is great news for those who lost DRM keys and want those features back. It's the next best thing to getting LB root.
[Xperia Z3 Compact General] dew.man:
Confirmed

Encouraged by the reports of restored functionality, I went ahead and unlocked my bootloader, followed the instructions, and can confirm that the process does work on 5803 running .77

I took several low light pictures, and they came out without any noise just as they did prior to unlocking.

Awesome!!!

[Xperia Z3 Compact General] aardappel12:
How is the audio quality? It was confirmed that the audio quality of the speakers degraded after losing the DRM keys, how is the audio quality after restoring the functionality?
[Xperia Z3 Compact General] gibihr:
I haven't noticed audio quality loss after losing drm nor after restoring it.. Equalizer still working, as well as clearaudio
[Xperia Z3 Compact General] FSRBIKER:
I'd wait a while longer to have people figure out what is or is not still lost after unlocking the bootloader.

Just so you know you DO NOT GET BACK THE DRM KEYS, this method simply tricks the system to thinking the keys are still present. The DRM keys are gone forever once you unlock, the only way would be to back them up before unlocking the bootloader but that's not possible without a root exploit.
[Xperia Z3 Compact General] XQC:
Additionally to that, as I mentioned in the bounty thread, the hole / bug that DRM hack is using might be closed in future updates (Lollipop). This should also be taken into consideration before losing the original DRM keys forever.
[Xperia Z3 Compact General] boojay:
Has that actually been confirmed, i.e. that PS4 remote play doesn't work? And in particular, by any of the recent Z3C users who've successfully restored DRM functions?

I'd be surprised since I recall seeing threads where Remote Play had been ported to other non-Xperia Z devices.

Disagree, I tried PS4 remote play last night for the first time (on my Z3C, bootloader not unlocked yet) and it was pretty awesome.

I'm not a gamer, but I imagine I was playing a pretty graphic intensive game--Last of Us Remastered--and the detail/quality was quite impressive, not to mention 99% of the time there was no lag and the connection never dropped. The controls were just as responsive as if I were playing on my TV. I played in bed about 40 feet away from the PS4 and router.

Hi, that is very exciting to hear, could you outline the procedure you took to unlock, and then mod your phone to restore the low-light functions? What ROM are you using and can this all work while keeping the Sony ROM in place?

I'm a salesperson. My customer buy this device then they go back to ask me that :" Why was my device lost the DRM key ?" I really do not know how to explain for them.

[Xperia Z3 Compact General] frank spectre:
Camera performance with other camera apps?

To me "noise reduction algorithm" etc. sounds like a task of the camera app. My guess thus is that a DRM loss would only affect the original sony camera app? Or am I wrong?

The thing is that I am very happy with Open Camera on my locked z3 compact, even under low-light. If this would not change I would definitely unlock and get a custom ROM.

Cheers, Frank
[Xperia Z3 Compact General] TheLostOne:
I have just bought a z3c. It was stated as new but in the service menu it says "bootloader unlocked: yes". So obviously it has been used before and the DRM keys are lost.

The quality of the camera is important to me. How can I check the affect on the camera without having previous pictures?

Android version is 5.1.1.
[Xperia Z3 Compact General] someone755:
Place the phone on a straight surface, open the camera app, turn off flash, and set it to auto mode. Take a picture (preferably in a darker room, it should come out as just a black image).

Now, open the image details (open Album, open the picture you'd just taken, and press Details). If the image is indeed only darkness, and the DRM keys are intact, you'll see that the ISO value is 12800. If they have been tampered with, or the image you've taken isn't completely dark, that number will be smaller.

It's a quick and easy method. Not bulletproof (the DRM keys may be gone but the seller may have flashed the DRM workaround zip prior shipping), but close enough.
[Xperia Z3 Compact General] muken:
I have created 2 images so far both in same mode in Superior Auto:

Z1C with DRM keys: https://drive.google.com/file/d/0BxOKUpz6QOnRaXFHcjJ0Yk5FZms/

Z3C without DRM keys: https://drive.google.com/file/d/0BxOKUpz6QOnRdF85YmZ1dTRRcDg

You decide :)

Edit: I also tried manual 20MP photos, but with about the same result...

Edit2: It's like the crispiness of the images are lacking in Z3C without DRM
[Xperia Z3 Compact General] tocirah1:
Looks like there's a bunch of Chroma noise and blur in the Z3C shot which is missing in the Z1C shot. The Z1C also looks sharper.

Did you move your hand a bit more on the Z3C shot? The reason I'm not a fan of using Superior Auto is that you can't necessarily be sure what shooting mode the software decided to use and whether or not features like Image Stabilization were applied.
[Xperia Z3 Compact General] muken:
I took several shoots to be sure since I noticed that my self. Every shoot comes out more "blurry" on the Z3C without DRM then on the Z1C with DRM.

Seems like some sort of processing is missing.

Edit: As I understand Sony takes multiple shoots and then compose a single image from them in order to increase dynamic range and supress noise in low light. It seems like that function is missing without DRM.
[Xperia Z3 Compact General] tocirah1:
Yeah sorry to hear that then :(
[Xperia Z3 Compact General] muken:
Yep. Not very happy about Sony right now, since I even called their support to see if they could say what were going to be affected by DRM. Their answer: "We don't know, but purchasing music will probably be affected..."
[Xperia Z3 Compact General] tocirah1:
Taking another look, it looks like the Z3C's photo is overexposed compared to the Z1C's. I'm not sure why that would be considering the have the same settings...
[Xperia Z3 Compact General] muken:
It's probably due to the lack of Sony's proprietary processing to reduce noise and increase dynamic range by combining multiple images.
[Xperia Z3 Compact General] LastQuark:
DRM is Digital Rights Management. Sony invested in a company called InterTrust in the 90's that provide digital protection to copyright owners primarily music and movies. The DRM keys are digital signature that identifies you as the owner when you buy online music that are DRM protected. If DRM keys are gone, you cannot play DRM protected music or videos. It doesn't have anything to do with the quality of the camera output.
[Xperia Z3 Compact General] SenK9:
If this is true, this would be quite a revelation. Affecting picture quality negatively for rooting? Unheard of ..
