Bravia Engine 2 seems stop working after bootloader UNLOCK

After bootloader unlock, two screenshots of one of the pre-load pictures in Xperia Z C6602, and i think they are identical:
BE2 ON:

BE2 OFF:

update:
after reading nexx67's post, i decide to give Youtube a try and guess what!
The Bravia Engine 2 is still WORKING! at least for Youtube video.
BE2 ON:

BE2 OFF:

And i don't know why BE2 stop working with still pictures but still working with videos. I sent an email to SONY Xperia support 4 days ago about Bravia Engine 2 and they never reply.:crying:

This has been confirmed already for all Xperia devices.
Unlocking your bootloader results in a loss of DRM keys - FOREVER.
Without DRM keys, you won't be able to use things like GraceNote Music ID, and... Bravia Engine.

I have unlocked and rooted my device and i can use bravia engine gracenote etc I cannot declare why.

The option remains because it's built in to the Rom. But does it actually work because of the DRM. It's like a button without a function after unlocking the boatloader.

yes but the gracenote plugin gives me the correct names and album pictures and music id identify the music from my radio. All this features does not function if the drm keys would miss.

They are identical yet say nothing at all. Bravia Engine works at runtime, a screenshot does not reflect the changes it does. You'd have to enable BE, display a picture, take a photograph of the display with a camera, go back, disable BE, display the same image take a second picture to compare. As BE-effects are quite drastic, this VERY UNSCIENTIFIC approach should still reveal if BE is working or not.
Another approach would be to visit a store where they have a working unit on display, load up the same pic on both devices, make sure BE is enabled on both devices, if your unlocked device differs noticeably from the demo unit, you know what's what.

Music ID != TrackID. TrackID works since quite some time as it's freely available on the market and also works on other manufacturers devices.
Gracenote supposedly works on unlocked devices since JB the Xperia T revealed (I believe). Users with unlocked devices couldn't use this walkman feature, after the update from ICS to JB - still unlocked - they could.
Thus I take it, BE is not working on your phone anymore as it is with every other, more or less recent and unlocked Xperia. You just can't tell due to the lack of comparison. Hence I'd say do that camera thing or do the store demo thing, whatever is more convenient to you if you want to know.

I'm new to all this rooting stuff - does it mean I will not be able to get Sony features even if I do a full factory reset?

AW: Bravia Engine 2 seems stop working after bootloader UNLOCK
I suggest you do some reading in the wiki, ask google about certain topics etc. as this is a very basic question you should be able to answer yourself before starting to tinker with the device.
The only feature you'll probably lose (until confirmed otherwise) by unlocking is the Bravia Engine. All other features continue to work as advertised.
Note: unlocking does not equal rooting. Unlocking just means you're free to run ROMs, more specifically kernels which do not come from Sony. Eg. third party Android releases if you wish.
Rooting means obtaining write access to the /system partition. Rooting an Android device is about the same as Jailbreaking an iPhone. Rooting can - once an exploit is found - be done without unlocking your bootloader. This has not happened yet for the Z, so you have two options for the time being. A) live without root until an exploit is found or B) unlock and run a third party kernel which force-removes (technically soso lala but you get the idea) the write protection of the /system partition.
A factory reset on the other hand does nothing else than clear all user generated data on the device, eg. it wipes your stuff. It has nothing at all to do with root, it does not do low-level operations like tinkering with the bootloader lock status etc.
Unlocked = unlocked and also for the time being, stays unlocked. There will eventually be a flashable FTF file by one of the cool devs working on the device which will relock the bootloader. It will not restore Bravia Engine (given it's disabled upon unlock) though. If it gets disabled, you'll lose it for good.
Hope this helps.

Nothing to do with "Sony Features". What u lose is DRM keys for the device, which means no BE2. Even after Factory the keys should remain gone.
My plan is too root and if I get an unlocked bootloader I will unlock it later on when people create ROMS with working BE2, IF that is possible.

If yes How ?
I am coming from HTC world (DHD HD2 then Evo3d) and i do Not know a lot of Sony stuff yet but i am Reding a lot to improve my knowledge.

Not yet, you have to wait for an exploit to be found. Should take maybe a couple weeks, not too long though, usually.

LOL, love the way you just thought it was going to be easy!
HOX has been out since april last year, and still noone has achieved S-OFF!
The fact that Xperia Z does have a locked bootloader makes me not want to buy this device... Probably!

1. There is no such thing as S-ON/OFF on Sony devices.
2a. We're talking root with locked bootloader. Couple weeks, hands down.
2b. We're not talking unlocking unlockable bootloaders, this may never happen.
3. Xperia T, same device, same-ish platform, root and CWM as well as TWRP recovery with locked bootloader is done for quite some time.

Hi guys,
I just received my xperia z and I unlocked the bootloader. Only after that I read this thread and I was a bit disappointed by loosing BE !
But I made some tests and the music ID (not trackID) still works (download completed OK) and the bravia engine seems to be OK (there is a difference with ON/OFF), do you think this is possible ???

Well if that is the case with this one I truly apologize. When I bought the HOX I really thought to my self it's not going to be a problem
because someone is going to find an exploit in no time and acquire S-OFF.... But it really did not happen, and still hasn't, so sorry if
I am a little sceptical!

Be sceptical, that's all right and even good. Helps you keep your device intact. But we here "only" want root on locked bootloaders and not complicated stuff like S-OFF which means tinkering with the bootloader and partitions and I believe even directly hacking around on the EMMC to get it done. Respectively not, as time showed. But something as "simple" as root is only a question of days/weeks, definitely not more. Or it's even done already if you'll take the plunge and unlock your bootloader.

The problem is that on a device like HOX it is simply not possible to acquire root without unlocking the bootloader (either official HTC DEV or S-OFF).
It is of course possible if you find a way to circumvent the write protection on the system partitions, but this has not been found yet. So if Sony has
decided if the write protection does not have to be all that secure it might be as easy as on the other Xperia devices. I just would like to see that
for my self before I throw my money at it.

Not true, you can see the difference on screenshots.
And about gracenote and download music info:
It also makes use of the DRM keys, but it also has a second thing related to it. There is a DHCP control which is probably disabled or makes an exception now for the music download funtion.
Or maybe Sony didn't link it to DRM keys anymore

Well I hope so. The device is (not even widely) available since 4 days or so. And if it's all tightened up, my oh my, I'll just unlock it to get root. Not being rooted is almost unbearable...

[Q] is it possible to get bravia engine 2 back?

hey guys, im new to this forum,,
anyways,
i know that unlocking bootloader will take away xperia z's bravia engine,
but if i relock the bootloader again, will i be able to get it back?
opinions pls :<
P.S. : does losing bravia engine is a really big deal to you?

For now there is no way to get BE2 back after unlocking.
Maybe in the future, no one can tell.
Kind regards, Stefan.

thanks for teh answer thaevil0ne, btw, do you think losing bravia engine is a really big deal?

For me, not at all.
I unlocked the bootloader even before checking out the BE, as I want custom kernels.
As far as I understand it will only work when you view pictures or movies with the Sony Album app.
If you browse the web or play games the engine will not be active at all.
Kind regards, Stefan.

Hey folks,
we often heard now that BE2 can't be brought back after unlocking bootloader.
My question is simple...WHY?? Maybe some dev can answer this question. I don't understand where's the link between unlocking and the BE2 engine. And why does this only affect pictures? That makes no sense...
In addition to that, there are a lot of ROMs for other sony devices which bring BE2 to them. Why shouldn't it be possible to bring it back then?
I understand that thing with loosing DRM support because of security issues...but an graphics engine....?

When you unlock the bootloader you lose things called DRM keys, these can never be restored after unlocking. These keys are used to make specific functions or features work. After you unlock as these keys are no longer there so some functions won't work. Sadly bravia engine is one of these things that stops working.

Has anyone tried this method: http://xperianeoldev.blogspot.be/2013/05/tutorial-install-bravia-engine-2-on.html ?
I asked the author of this tutorial if it would be possible to make similar deal with XZ and it is what he answered:
"Yes , use the tutorial given in the website it is working on all xperia smartphones"
Still hope to get BE2 back!

For all people here you will brick your phones. Unlocking your bootloader you do not loose bravia engine it was told 100x times read forum

bravia will be loss in album but video still work.

That's still half not working

Bootloader unlocked but I still have the option to turn BE2 on or off. I can't decide is there any difference when it's on then off...

It surly does not work with the pictures.
Bth I had a few smartphones as far: iPhone (jailbreaked), HTC HD, S Galaxy Nexus, Galaxt Tab 7, and have never had problems like this that I irreversibly lost such important features after unlockimg the bootloader. Of course it is only me to blame as I should have done more research before but bearing in mind my earlier experience and the fact the instructions were taken fron offical Sony site I just felt too self confident.
Anyway I think next time I will not choose Sony smartphone as I am bit dissapointed with the situation esp. when you see BE ported on devices from HTC, Samsung or others.

Do you still have the option for BE2? I also thought we lost the ability to get track info and movie info from Gracenote, that's still working fine for me. I don't do DRM so it's no loss to me.
I've not used other devices much, I vaguely remember with Samsung you're sideloading the firmware as opposed to Sony where you're unlocking to freely change the firmware... Correct me if I'm wrong.

Yes I do. The button BE2 is still visible in my settings but there is no difference if I turn it on or off. For getting track info it is similar - I can start this option, wait until is finished. Then start it again and exactly the same number tracks is updated. You can repeat the process all over but in fact nothing is changed.
I don't know what you exactly mean "sideloading" but when I had Galaxy Nexus I could freely change the firmware, could have f.eg. JB with Touch Wizz from S3. Of course had no BE2 at all but the screen was more vivid so the pictures looked better (my opinion) than on XZ without BE.
Anyway there are mods which allow to install BE2 on devices from HTC, Samsung, Motorolla or other unlocked Sony models and that makes me even more disappointed.

I still have the ability to use the Gracenote services, I updated all my music and it replaced the cover art, I also did the same with my movie & tv show collection.
On Samsung i believe the system is less secured when it comes to installing other firmwares hence the ease with which it's done. Firmwares can be installed without unlocking unlike Sony. (this is not my direct experience with Samsung only what I've heard)
As for BE2 it can installed on other devices and according to a post i read last night it's theoretically can be done, but not yet tried.

[Q] Unlocking any downsides?

Hi there, i've got an Z1 ordered wich should be delivered tomorrow or the day after.
I've read a few threads in advance and even checked out some roms wich will suit me
I've got a question though;
It's not that beginner stuff, i have a sxs and i know what to do to unlock the bootloader and flash cfws.
I've read some posts about having camera issues in CM11 and that is has something to do with unlocking the bootloader (link)
i'm honest:i haven't read the whole thread so sorry if that issue should be resolved now.
now the point of this thread:
is there anything that can f**k up my device when unlocking it while completely following sony's guide?
or should is there another foolproof method?
next thing:
i've read alot about that touchscreen bug. if i have this bug, do have it right from the start or can it also happen later?
i don't want to unlock my device and then after some time falling victim to this bug.
last question:
if anything happens, worst case scenario:
i've unlocked my device and something happens to it. can i relock my bootloader without sony knowing that it was unlocked?
thanks in advance

Before Unlock Bootlader you have to root your phone and Backup TA and DRM keys, then you can Unlock or reLock your Bootlader.
Should be covered via warranty if the Booloader is locked, so if you Relock your Bootlader should be too.

I haven't read about any bricks just from unlocking.
Most bricks happen when going from 4.2.2 to 4.3

do you really have to backup TA and DRM keys? i didnt do that when unlocking the bootloader (it took me 2h to unlock it and install a custom ROM, didnt have time to flash 3 ROMs just to get root and be able to backup TA/DRM)
afaik DRM keys are only needed for bravia engine which many people think is useless and even worsens image quality due to heavy sharpening..

X-Reality, Bionz and Bravia engine all sound like marketing gimmicks - especially x-reality/bravia engine which does nothing for image quality, use of TFT displays is Sonys biggest problem and no software enhancement can solve that (HTC still makes the best displays on the market)
and Bionz didnt help Sony make best smartphone camera on the market
the way i look at it, its just like having AOSP/Google device..

So you have your reasons and it's just you on 50 people without warranty. You also can't relock the bootlader but I think is not a problem for you.

i don't know of camera quality yet, since i still got those factory screen protectors on my z1 (those ugly ones wich you have to peel off). i'd like to keep it that way until i get my third party screen protector. i'm a bit clumsy and i don't like the thought of having scratches on sonys stock protectors. i will get my screen protector + case tomorrow
i'm halfway through unlocking the phone. it came with 257 (4.2) t-mobile branded, so i had to downgrade to 534 to get root. ive had to read alot before downgrading, i wasn't really sure if drm keys stay if i just downgrade via flashtool. took me a while too get those firmwares too .
the biggest problems i had were with my adb drivers. I had a SXS before, where all was pretty smooth. But i had dozens of problems to get those adb drivers for my z1 to work. Normally i don't have any problems with such things as drivers but those really got my nuts :/
Windows installed drivers of their own, wouldn't let me overwrite nor delete them. Either the drivers were to old or wouldn't fit device (wich was a lie). Good thing i have a ssd, because i've punched my desk more than a few times
now i'm on 290, with root and recovery. i have a backup of TA partition, and next thing i'll do is unlocking the bootloader.
second:
at the moment i lack of a rubber mat, so i can't really test my screen. up until now i haven't noticed any problem with the responsiveness of the screen. i'll report back if im through with that.

Nice, sorry i think the thread hijacking was my fault
Anyway z1 camera is as good as xperia s camera, sucks is lower light levels but besides that its amazing,

Unlocking bootloader disadvantage?

I have searched and asked this many times. But no one seems to have a answer for me. So let's see if someone on the Q & A thread will...
I have a Z1 that can be boot loader unlocked. However I don't know whether its worth it.
The biggest thing to put me off was loss of x reality but there is a solution now.
The biggest thing that is putting me off is camera performance. I heard it removes Sony software for the camera called BIONZ. I want to know if anyone can tell the difference in camera quality with their unlocked boot loader as opposed to a locked boot loader.
So any answers appreciated!

Well there is a thread somewhere around here called another Sony secret and they are talking about the difference between pictures with an unlocked bl and pictures with a locked bl...the op said that there is a lot more noise in the pictures with an unlocked bl...look for that thread and you will find more info

Well I have mentioned this earlier.
This has had no negative effect on mine. I saw a camera improvement overall in .290, but other than that I have not been very satisfied with 4.3.
.257 had way less issues (talking about firmware as a whole here). Fingers crossed for kitkat:fingers-crossed:
So what I'm saying is, weird that I can percieve better results going from locked .257 - to unlocked .290.
I've read around that mentioned thread, and to me there was heavy speculation going on in there.

That thread was rated 1 star last time I checked so was not sure if it was true, plus, they were on bout low light mostly. I want to know about good light
I think I might just go ahead and do it Just hope I don't regret it as I take pictures a lot.

I'm sure in good light you won't notice the difference so just go for it... Don't forget to backup all the important stuff like TA etc...

@technostein
Unlock bootloader and try, if you don't like it just restore your TA and you are back again...
Just be sure you are on 4.3 because of camera...
I was always unlocking bootloader but I bought Z1 (in purpose) with bootloader status - NO.
I'm completely satisfied with Sony ROMs ( back from 4.1.2) and can't find any reason to use custom kernel...
Just don't need that...
OC? Really don't need more cpu or gpu speed.
All other features are already in stock kernel...
Maybe, only, if Sony decide not to add KNOCKON feature- I would miss custom kernel - but who cares for just one thing...

Reason why I am tempted it because I run ihackers ROM 3.0 and I liked the changelogs of ihackers kernel. such as noise reduction in camera and loads of tweaks and build prop tweaks.

Be aware that by unlocking formally sony's guarantee will be lost, as that is stated in their terms. I don't know if relocking will fix the guarantee issue of there is a need later on.

I saw somewhere on XDA a thread about differences quality pictures between Locked and Unlocked Bootloader and the pictures on Unlocked Bootloader had much more less quality and more noise than the one with the Locked Bootloader. I can't guarantee the accuracy of that information but if it is true then Unlocking Bootlader is very bad for the quality pictures. I am sure it can be fixed because of software related but how and when I don't know. I still keep my Bootloader Locked even if I am tempt to unlock it to install CM11.

Consequences of opening / unlock the bootloader

Dear all,
since last week I own a Xperia X Performance (upgrade from Xperia Z3 compact). Unfortunately at least at the moment it seems there is no chance to root the device without open / unlock the bootloader. Fortunately the developer area has certain instructions to accomplish this, but...
As a consequence you loose the infamous DRM keys.
My question: is there by chance any proven / solid information what you actually loose if the DRM keys are gone?
- Which Sony Apps no longer work?
- Is it true that the camera app will take worse pictures? Or just an urban legend?
- Besides OTAs no longer work and you will have to use a flashtool or companion, anything else?
Any other consequences besides the lost keys?
It would be highly appreciated that someone could state some facts, not rumors...
Thank you.
Best regards
Michael

If you read the kernel thread you will find all answers.
The only thing is that OTA updates will not be an option.

Thx.
But all I can find here and on Sony's sites is that there might be some restrictions due to missing DRM keys - but no clear statement and facts.
Nevertheless, after release of Nougat I guess I will unlock the bootloader (if then it is still possible and kernels / root is still available)...

Mights that are mentioned on the developer sonymobile site:
Certain pre-loaded content on your device may also be inaccessible due to the removal of DRM security keys. For high-end devices running recent software versions, for instance Xperia Z3, the removal of DRM security keys may affect advanced camera functionality. For example, noise reduction algorithms might be removed, and performance when taking photos in low-light conditions might be affected. The secure user data partition may also become inaccessible, and you will not be able to get any more official software upgrades if you unlock the boot loader.

There has been made a workaround for all of these things. The only thing you won't get is OTA and warranty.
