So it was confirmed by a Sony employee that unlocking the bootloader on the Z3C results in the loss of advanced camera algorithms which affect low light photography. This had me wondering whether this is the same on Z2?

It seems the algorithms are protected by the DRM keys and once these are lost the functionality becomes limited.

I unlocked my Z2 just before the root exploit and lost my keys. I didn't notice a drop in camera quality, but did anyone else?

Does this put you off buying a Sony device in the future?

Personally I use a DSLR and my phone is just for quick snaps so it's not a big deal, but for some it will be.

Discuss.

Link to confirmation here.
[Xperia Z2 General] nrgleon:
I after purchase of phone reflected to open bootloader, but nevertheless decided to wait there will be root on the closed boot so far, and I made to myself a backup, strange but for some reason when by missing drm keys, xreality dosn't work, and modify supervivid, and the way so far to restore work or to make working supervivid and xreality on the unblocked bootloader isn't present :(
[Xperia Z2 General] Envious_Data:
I dont think this is generaly true unless we have solid evidance becsuse sony only made the quality dim after BLU on Z1 because it protected sonys methods of image proccessing

They made it untouchable in Z2 so why would they revert to lesser tech again

Also that link doesnt fully conferm much, this may potentialy be a hicup from sony

Edit- now that i think about it.. Since it is new camera tech they may have had to do this due to not being able to lock their content like they did with Z2
[Xperia Z2 General] chesterr:
It is true I experienced myself after I backed up my TA, First thing I did was unlocked the bootloader and checked the camera quality and yes I saw that camera quality was decreased and I earlier mentioned it before and no one believed me lol, Even though if you think that it doesn't with future updates such as 4.4.4 android L you might see the changes of the camera due to permanent lost of DRM. So we gotta find a root method for Z3. :D
[Xperia Z2 General] Envious_Data:
Fair enough

Lets hope sony fix this like they did with Z1

I plan to continue buying xperias untill im dead :D
[Xperia Z2 General] chesterr:
Haha so true man but since Sony mentioned that they are having their bionz thingy tangled with DRM keys, I don't think they'll ever fix. Only thing is that we'll need have locked bootloader always. Even if I'm upgrading to Z3 I'll be patiently waiting for LB root before I unlock it ;):laugh: I hope xscha comes to action. He was the one who actually came up with the method. Great guy he is. :o
[Xperia Z2 General] Envious_Data:
Well drm keys have been an xperia problem for a while and funny enough they souly exist to protect other OEMs from stealing from sony

Not realy there to stop users being users

Lets hope they find a new way to protect their new content
[Xperia Z2 General] rodritank:
How about relocking the bootloader? Will it restore the image quality?
[Xperia Z2 General] effective:
No.It loses BIONZ and X-reality.
[Xperia Z2 General] Batfink33:
Restoring a backed up TA partition does though, does it not?(on the z2).
[Xperia Z2 General] effective:
Can't give you an answer here.Have an ZR and yes it brings the DRM keys back.But for the z2 im not familiar.
[Xperia Z2 General] rodritank:
I am very, very disappointed about Sony's move. It makes no sense if you come to think of it.

Since I bought it Monday and my country has a strict return policy (good for consumers), I *might* be able to get a new one without explaining what happened.

However, if I can't get a new one, what's the next step? Download a camera mod perhaps?

EDIT: X-Reality WORKS. I am just not sure about BIONZ. And perhaps future Playstation stuff.

Can anyone with a locked bootloader take a picture of a dark room with a candle? That's easy for everyone to reproduce... and we can compare shots.

[Xperia Z2 General] rodritank:

[Xperia Z2 General] effective:
Don't worry ^^ There is nothing wrong with your camera.
[Xperia Z2 General] vidge1111:
This also happened to my z3 after BL unlock.. lots of noise on pictures specially in low light shots.
[Xperia Z2 General] rodritank:
If you come to think about it, it's not thaaat bad. It noises just like an iPhone would do (which, for me, isn't a big deal).

It seems the only thing the DRM does is to apply a filter/denoiser/blur to the pics.

Is this related to BIONZ? If BIONZ is a hardware feature, it's most unlikely that an unlocked bootloader would do anything (unless it's like the Xbox 360 and e-fuses).

X-Reality is pretty lame to be honest. It justs "HDRs" all of your images. Nothing too serious. And it only does that to images and movies, not the UI.

Now I am just concerned about future Playstation features like of that stream thing - remote play for PS4.

[MENTION=3428319]effective[/MENTION]: did you do anything to your pics? They seem to miss the EXIF data. I wonder if a Locked Bootloader would produce a different JPEG header?
[Xperia Z2 General] effective:
[MENTION=6063359]rodritank[/MENTION]: No - I didn't.Can you light me up what EXIF data is ? And yes i am with locked bootloader,but for me i felt a drop of the quality of my pics when upgraded to .314 firmware.Don't know if its from this or some hardware problem,but since i updated the phone It can't reproduse good quality landscapes.The focus is lost on the edges and the sharpness is lost there also (in manual with multifocus also). Im waiting for 4.4.4 to see if theres any differences.Because there are focal length fixes too.
[Xperia Z2 General] rodritank:
EXIF is some data within the image file that tells with which camera you took the photo, data, place, etc. :) perhaps your EXIF data has been wiped by the site you uploaded the images. Can you reupload them to imgur?

That's an interesting report, though. If quality has really decreased after some update, it *should not* be impossible to revert the DRM post-processing (denoising) back to normal on unlocked bootloaders. Since it's software after all...
[Xperia Z2 General] Anonymuszymus:
So there is hope to revert the losed DRM keys?how is this possible?
[Xperia Z2 General] vidge1111:
No
[Xperia Z2 General] TheFerhatKing:
I really don't know if I should unlock the bootloader or not :/ I just want all features like x reality and the camera quality and I really don't know if I lose now someting or not because some people say we lose nothing and other people say we lose this and this etc. I don't know what is now the right, losing features or not??
[Xperia Z2 General] Envious_Data:
Backup your TA partition before unlocking your bootloader

And i doubt sony wont fix this, they did with Z1 a while back, at the time sony had figured out how to protect their content
[Xperia Z2 General] jaffa1980:
Would it affect you if you backed up then restored the keys after unlocking the boot loader?
[Xperia Z2 General] vidge1111:
for z3, once bootloader is unlocked, you will notice camera quality downgraded, Bravia engine (xreality, vivid) no longer working and some other features (Miracast, Mirroring etc). PS4 remote said to be working. For some older Z's, camera didnt work after unlocking the bootloader. I would advise against unlocking the bootloader for now.

---------- Post added at 05:47 PM ---------- Previous post was at 05:44 PM ----------

Backing up the TA partition will require your phone to be rooted. Go for a root exploit, backup your TA then unlock bootloader to install custom firmware and roms.

You may re flash your TA and use stock kernel, firmware and AOSP rom. This way, drm will be intact and you can use Sony features.
[Xperia Z2 General] chesterr:
Or you can use DevShafts tool to back up TA and then unlock the bootloader.

while you're on unlocked boot loader it's better if you back up TA there too cause if you want to unlock BL whenever you want you can simply restore Unlocked bootloader TA and try new CM builds or custom kernels then. whenever you feel like going back to stock restore Locked bootloader TA and re-lock it, and you're all good.
[Xperia Z2 General] jkyoho:
Will restore TA partition overwrite recovery? I backup TA before unlock BL and now having XZDualRecovery w/ stock 314 firmware RooTeD
[Xperia Z2 General] TheFerhatKing:
I know I can do this but why I should unlock the bootloader if I want the features all the time and not only then when I send my phone to repair (bootloader locked again with TA Backup)?? I want the features with unlocked bootloader.
[Xperia Z2 General] BULL3TPR00F:
no TA partition is its own separate partition.
[Xperia Z2 General] vidge1111:
Will Devshafts backup tool work for an unrooted z3?
[Xperia Z2 General] jkyoho:
So, after I restore TA partition, I would have DRM keys BACK! with XLDUAL recovery and root? ??. :cool:

NOTHING missed after relock BL?

sorry for noob question, lack of exp on xperia phones
[Xperia Z2 General] chesterr:
Unfortunately nope brother, that's what holds me back buying Z3 cause no root on locked bootloader and it'll take some time to gain it. Since Sony has fixed ASEC vulnerability and it ships with 4.4.4, it's gonna take a longer time. But you can try this method and tell us if it does anything. http://xdaforums.com/showthread.php?t=2781109

This was the first method that great xsacha found out to backup TA.img. Then RyokoN and cubeundcube made that RIC disable and achieved root, I hope it'll be the same with Z3, I recon you stay bit longer without unlocking bootloader.
[Xperia Z2 General] rodritank:
Just to reiterate: for now, the only "feature" that is not even 100% confirmed to be lost on the Z2 is low light denoise.

And that's it. Everything else (X-Reality, update using Sony PC Companion if you relock the bootloader, Video Unlimited) should work.

DRM keys are indeed lost, but it's features should be recoverable if a skilled dev works to reproduce them (since we already have an unlocked bootloader).
[Xperia Z2 General] kamalmawa:
It's official for Z3. Sony says "For high-end devices running recent software versions, for instance Xperia Z3, the removal of DRM security keys may affect advanced camera functionality." http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/

[Sony Xperia Miro, Tipo (Dual), J, E] NSDCars5:
Actually, it's a triple recovery. CWM + TWRP + Philz. CWM and Philz are from CM11, and neither of them can mount internal storage yet. Hoping to fix that soon, though...
[Sony Xperia Miro, Tipo (Dual), J, E] KkdGab:
So there is going to be a boot loader that has the option of booting into one of them?:D

Sent from my HUAWEI Y210-0100
[Sony Xperia Miro, Tipo (Dual), J, E] NSDCars5:
When you have CM10 and Hades kernel, the phone shows a blue light for TWRP, green for CWM, right? Same way, now you get pink for Philz too. :D

Wait... you're the one who doesn't have an E, right? The E doesn't have a recovery partition - the recovery has to be built into the kernel ramdisk. There was a kernel with two recoveries - I simply extended that and added three recoveries to the kernel ramdisk, and options to boot into all.
[Sony Xperia Miro, Tipo (Dual), J, E] NSDCars5:
Actually, cut the triple recovery, at least on stock. CM11, maybe, but stock won't work - vold managed partitions in KitKat recoveries don't show up with stock.
[Sony Xperia Miro, Tipo (Dual), J, E] TiVON:
If you want to build a properly working CM10 there is a lot of work to do.

jjm34's device repos are messed up and incomplete. No offence to him, or any of his skills but it's even a wonder the ROM boots.

It would be best to start from scratch, but that's a pain.

I do not own the device anymore, but for my current phone(the almighty bacon :D)there already is a ton of development so I think you guys would appreciate my help more than they do.

Anyway, I'll have another look at the source again this Saturday to see what I can do.

-Peace

---------- Post added at 10:20 PM ---------- Previous post was at 10:18 PM ----------

If you really want to, I might know a way to do it, but Xperia devices have always been annoying things to build kernels for.

Anyway, it would require a lot of "hacking" and chopping up code to work, but it might be possible.

Again, why would you want it?

---------- Post added at 10:28 PM ---------- Previous post was at 10:20 PM ----------

Oh, and your CM11 source is also messy. You merge commits like it's nothing and don't organise them. Make a list of errors and eliminate them one by one.

Don't do all sorts of stuff at the same time, it causes confusion for others who want to check your source.

I shouldn't be such a know-it-all, but I always am, sorry. :p

Please don't take this the wrong way.

Just A Suggestion !

What About Resting Now and wait for Android L to be released { maybe 16/10 } and make an unofficial build of CM12 {when released} ....

For Now , I think that You Should make the team that will work on this ROM and develop it .

You are true that CM9 And ICS is kinda outdated now and many apps and features will not work on it .. So it is not a good idea

CM10 is approximtly Stable So it doesn't need development { except for the camera which will take long time if you try to fix it }

So i think that working on Android L and trying to make it the first { and last } ROM that has no bug would be the best Case

I know that it is hard but i think that will be the best Thing that could be Done :)

i hate that bcoz once i lossed my baseband while travelling no network :eek:no phone call that was very bad experience
[Sony Xperia Miro, Tipo (Dual), J, E] Louai13:
Oh , i have just remembered

This happened to me 1 or 2 times only in last few months

AnyWay , What do you think that is better ?!

{ Trying to fix CM10 , Making CM9 , Or Try to make CM12 when Cyanogen release it }
[Sony Xperia Miro, Tipo (Dual), J, E] NSDCars5:
Not necessarily. For example, porting Gingerbread to, say, the Xperia Z3 would be really hard.

CM9 doesn't have support of any kind for the E. CM10 at least has an FXP device tree to start with. It'll actually be easier to port CM10.

Plus, unless you're gaming, the difference between stock JB and stock ICS is barely noticeable (both on 1 Ghz). CM10 vs CM9 should be the same - only gamers would have any use for it. And I'm pretty sure nobody buys the Xperia E for its gaming prowess. :P

I have a SGH-T989 that I want to get the Carbon KitKat 4.4.4 on, but I need to install CWM 6.0.4.3 on it first.

- I tried booting the phone into recovery mode and selecting update from external memory, but I get a E: Verifying Signature Fail.

- I look up how to get around this, and find the Odin flash program and a compatible rom file could be the key.

- I boot my phone into download mode, plug it in to my computer, have Odin firmware update the CWM 6.0.4.3 on to the phone, then reboot the phone.

- When I try to boot the phone into recovery mode, my phone gets stuck on the Samsung splash and won't progress until I restart the phone and let it load up normally.

- The only way I have found to get back to my recovery menu is to use Kies and have it install the stock firmware on to the phone.
