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.

Sorry for my noob question but is it possible to root without unlocking bootloader ?
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.
Thanks for helping me while starting with this great device.

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!

Oh boy:

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] 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

If you have the problem then you have it already, you just don't know how to reproduce it. Unlocking Bootloader have nothing to do with it.

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..

warranty i didnt have from the start, so no loss there
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.
BTW, I have to admit you are right, X-Reality, Bravia seems not help and Bionz didn't made Sony best smartphone Camera. Z1 still making middle range pictures.

when unlocking your boottloader it breaks the camera right?
the 4.3 update suposedly fixed that, or is that a device or version spesific thing?
because im saving up money to buy a SXZ1 Direct from sony and i am hoping to.unlock my bootloader without having to worry about the broken camera issue

In daylight all pictures seems good, I don't like the quality of 20mpx and 8mpx in iAuto. Too much noise, many complain about that, just a bit of low light and Bam, expensive camera gone on the moon. I don't like the pictures, my personal opignion. The phone is good to me and if it's fake they really do a hell of job in China, still Made in China the Genuine anyway so no big difference!

Yes, the .290 update fix that and all working fine. Remember to Backup TA before Unlock Bootlader. You still missing X-Reality, Bionz processing and Bravia engine after unlock bootlader but the phone will working well and many ppl do not see any difference.

woah, my thread got hijacked...
i'd like to give feedback now:
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,

To me it is bad as there is a slight difference in quality then it not work properly, if not at all. We need concrete facts of what Unlock Bootloader damage on our phones and what, how the features still working. That what I didn't figure out yet.

I already unlock for a while to try doomlord kernel, x-reality i can't figure out there is different but camera is bad when unlock bootloader condition especially in low light,there is lot of noise , after relock i test in the same place and light and i can completely sure that bionz work on locked bootloader

Ive actually explained this before so i wont do that again. But here comes a theory why ppl belive the features aint working.
The cam stopped to work completley pre 4.3 right ? Ye back then the Bionz was affected hence the camera didnt work with unlocked bootloader. The camera itself cant work if the Bionz chip aint there. Google for image processing chips for cameras in general and find out what it is.
Although, Sony fixed theese issues with KitKat and here it comes, brace yourself. If you google this you will get ALOT of answers about it. Everyone suffered from bad quality photos since KitKat was introduced(even the normal users that never fiddles with their phones). So, NO it aint the unlocking of the bootloader that does it. Sony fixed all thoose problems ppl were having with unlocked bootloaders. It is the new software that does it. Media reviewers actually wrote about this aswell saying that Sonys cam wasnt any good no more. Google is your friend.
A bonus theory here: The "conspiracy theory" : Wouldnt it be smart to make some features look abit worse on the Z1 when the release of the Z2 is just around the corner ? If a customer wants a really good camera phone and just cares about that. And when he is comparing the Z1 with the Z2 and found that Z1 is just as good camera wise but half the price he would buy that one i would guess. Buuuut if you make sure the camera isnt working as good on the Z1 but super good on the Z2 while releasing the Z2. Then that consumer might buy the Z2 instead. It could very well be marketing stunts so the normal user would go "ehhh this Z1 aint working properly, ahh well ill just buy a new one like the Z2".
And ofc, when the Z2 has been out for a while the software will be fixed on the Z1 making the ones that didnt jump the train for Z2 happy again so that thoose might continue to buy Sony Xperia´s.
All big companies wanna make money. They have smart ways of doing so aswell.
I will buy a OnePlus One when that is released here, and if that is so good as it seems to be and that the company will continue to produce "flagship killers" to the half price and a more humane price. I will continue to support them instead. But usually everyone making money will get greedy. :laugh:

Green photos with unlocked bootloader

Has anyone unlocked their bootloader and when you take a photo with pretty much any camera app outside of snapchat. The photos are just solid green?
Sadly didn't understand this whole DRM key thing til after the fact.
Also has anyone been able to relock their bootloader, keeps failing for me. I'd really like to use android pay.
thanks

Have you thought of going down the AOSP road?
Might fix the camera.

Yea that's what I originally did, but certain things don't work. Like the front facing camera and fingerprint reader, and it's just not very stable.

I'm afraid u just thrown 600 bucks my friend... Nobody dares to unlock bootloader because the drm keys yet, everybody knows that... I don't think u will ever be able to restore your drm keys, since u didn't back them up... But I'll be happy to be wrong

The original DRM keys will not be recoverable, ever, but there's still hope to restore DRM reliant features via hacks like this or this. EDIT: Never mind the second link
Since @Meow_ has already unlocked the bootloader, maybe you can experiment with things a bit, see what works, maybe even do your own development if you're up to it. Good luck!

Almost all of the other Sony phones I've seen eventually get root and roms with built-in DRM functionality. Just wait a while.

Bootloader unlock & rooting

So clearly this is still very early days given the phone is barely released yet but this is my first Sony Xperia device and just wanna check if the following will be possible when I receive it...
1) use this website to unlock the bootloader https://developer.sony.com/develop/open-devices/get-started/unlock-bootloader/
2) extract the boot img
3) patch the boot img with magisk and flash
Thanks in advance

Ah just found this site too
https://www.ytechb.com/how-to-root-sony-xperia-1-ii-and-unlock-bootloader/
Will be great to root and get xposed + gravitybox!

Be carefull, unlocking bootloader gave in the past lesser features for the camera.

Thanks for the heads up, that's interesting and a little concerning! Hmm I guess we'll see how it goes...

Hmm seems perhaps losing such functionality could be avoided...
The link is not posting for some reason but Google "How to Backup and Restore Sony Xperia Z+ DRM Keys and Keep DRM Functionality after Root", perhaps this method could work

I've emailed Sony via the developers website whether unlocking the bootloader will result in losing camera features. Will post back here if/when they reply.
It'd be great to know, as if I get my device next Thurs I would love to get it rooted for substratum theming, ad blocking, edxposed etc

Here is Sony's response. Seems its gonna take a brave person to try this out! I think I'll likely just enjoy the device stock for a short while to get a feel for it and then see if unlocking is gonna be an option, as I wouldn't want to lose features but also I don't want a rootless android....
Perhaps the backup TA partition option (and the DRM keys) is the answer, but I don't know enough....

Not worth it in my opinion but to each his/her own.

Agreed, certainly at this point...
One of the best things about the phone will be these features, but I must admit if I can't root it I'll be a little disappointed.
Let's see how things go ?

If its the same as the Xperia 1 then you'll have nothing to worry about when it comes to the camera

This is great! Has there been any detrimental effect at all? I mean obviously unlocking can pose some risks but indeed so long as nothing breaks or I won't lose any of the great capabilities I'm buying this phone for, then I'll likely just root soon after receiving it ?

Here is a thought, why not first try the phone in stock ?
I mean i was all for unlocking in the past, hell i even created custom roms.
But that was the time that we could actually add new features to the phone.

Oh definitely, that'll be what I'll do initially. I'll spend a day or 2 (patience permitting) just completely out of the box fresh and untouched, the way its intended to get that feel for the device. It'll be my first Sony so I wanna see how it runs. Curious also if the advertised motion blur reduction runs well, in comparison to the 90hz I'm used to. I wanna see how the battery life holds up to my usage and I definitely wanna get used to the pro mode camera etc.
Then, I'll enjoy rooting (which by then perhaps others are posting their experiences too) for all the benefits that brings. Plus then there's custom rom support in the works too.
Oh I just love that new device feeling!

Only detrimental effect to the camera for the Xperia 1 was letting Sony write the software for it.
You'd lose the DRM keys so you'll lose the video enhancement, sound enhancement, widevine keys for watching stuff in HD and above in certain apps like Netflix.
Unlocking isn't really worth it in my opinion when software is pretty much stock Android with the DRM stuff.

Hmm so when you say sound enhancement for example, do you mean Dolby?

If I remember right it was the DSEE for upscaling audio to HD that was lost.
If you get the phone to focus on media then keep i'd keep it locked to be on the safe side. Let others unlock it first then see what they say.

I think I will just to be safe...
There'll be some won't care about the Sony features as such and may proceed to unlock right away.
I'll enjoy the phone as-is for a few days and enjoy it as its meant to be enjoyed and in the meantime will see how others get on.
Cheers :good:

Can you tell me what email address you used to contact them as I have a couple of questions that they could answer very quickly? Thanks...

If you learn anything useful be sure to share!

Apologies if this is a total newbie question, but do I have to unlock the bootloader to flash official firmware too? I'm getting the phone from O2 in the UK and wanted to flash EE or generic EU firmware to unlock WiFi calling.
