Hi guys I'm considering to purchase the Z1 beocz I lose my precious Xperia S a week ago :crying: (very very sad, really love it)
As I'm those type who will definitely root the device and probably unlock it some time later, I really care about the camera problem.
I read the the DoomLord thread which told us to backup the "TA" thing before unlocking the bootloader, so we can restore it and have the camera working again.
May I ask what the "TA" actually is?? how can I backup that thing??
So after I retore it, is the bootloader still unlocked??
If i screw up the TA thing, can I relock the bootloader and save the camera by the official repair function in Sony Update Service??
Sorry I'm noobish but plz explain these things to me thank you!!
BTW, are there something i should consider before i buy the phone?? Is it the right time to buy it??
thank you
Its a partition on the device called trim area.
There is a thread about backing it up and its very easy to do.
If you do not have a TA backup then relocking the bootloader will NOT fix the camera.
Also, do not restore someone elses TA it will hard brick your phone

How if I repair the phone with update service after relocking the BL?
And after I restore the TA, is the bootloader still unlocked??
I'm wondering if there's possible to keep both bootloader unlocked and the 20mp camera working...

Restoring TA relocks the bootloader
There is no way to have an unlocked bootloader and working stock camera
I'm getting a little confused!
After rooting + custom recovery + custom ROM, can I restore my TA to get the camera back? Obviously would like to keep root and the custom ROM.

Depends on whether the custom ROM requires an unlocked bootloader. Some custom ROMs don't need your bootloader to be unlocked. So that means you can still have root + custom recovery (which don't need unlocked bootloader) + custom ROM, and your bootloader is still unlocked and your camera is still working.
But if the custom ROM requires an unlocked bootloader, then restoring the TA will result in the bootloader being relocked, which means your ROM no longer working.
Someone correct me if I'm wrong.

Basically you can only use roms based on official firmware for now (and have a working camera) afaik. All the roms in the original development area (based on AOSP, custom kernels) required unlocked bootloader and as a result have a non-working camera.

it is possible to lock it without a backup, is your camera not working anymore ?
You can try flashtool, BLU option tries to relock it if it's unlocked, theres a good chance you will brick your device!
Have fun

Are you sure this is good and/or informative advice? I thought a locked bootloader not finding valid keys in the TA will refuse to ever function usefully again - no boot, no fastboot, no flashmode, nothing, totally bricked, and no way to convert it back to unlocked and get your phone back.
I would like to know if I am wrong about any of that. And... it seems that I was:
** Correction - it is Ok to relock the bootloader without having the pre-unlock data in the TA partition
** Flashing in data from any other TA partition (some other phone) seems certain to brick the phone though.

I've never read about those damages but I read things like the known camera bug.
I unlocked my Z1 on .290 - the Sony release which fixed the problem (4.3). I flashed a Recovery and rooted it with it and my device is working like it was with a "untouched" ROM.
That's all I know.
We could wait for a dev to answer deeper questions.

Yes this absolutely fine and is what I did with my Z1, ie do not unlock until after the 290 update is applied - you will see that advice on the Sony unlock website. However if you want a TA backup you need to do that before unlocking as the unlock process will wipe the keys, and you also need root in order to make that copy. (let me know if I am wrong about that)
My process was to root on earlier firmware, copy the TA, update to .290, then unlock. After unlocking full root on .290 is easy with a custom kernel and everything is good: unlocked, rooted *and* working camera.
But you *will* need a copy of the pre-unlock TA partition to regain any of the functions that use the DRM keys if you decide to relock the bootloader later.
It is impossible to get the DRM keys back, and there is no gain from relocking without them, all you're doing is locking down the bootloader without enabling BIONZ, etc, but you can certainly run a stock system if you want.

Hello, yesterday I downgraded to rooteable 4.2.2 rom in order to backup TA partition. Once I had backup, I updated to 4.3 (290) and unlocked bootloader, then flashed recovery. With recovery was easy to flash superSu. Now I have "stock" rom with root and unlocked bootloader, but I realized that x-reality wasn't warking anymore (because of the DRM keys loss).
I tried to recover TA partition, but I caused a soft-brick, wich I only could solve flashing a 290 ftf through flashtool, but I lost root. My question is: It is possible to have root and DRM keys (TA partition restored)??
Thank you very much.

So, apart from losing x-reality and some Sony apps functionalities (which I dont care). Do you lose something else? I heard about losing bionz processor, but camera still works, then I dont know how far this is true.
The incompatibility problem of root and restored TA partition, is because flashing recovery (which modifies kernel) or supersu.apk it self?
Thank you VERY much!
You loose bionz, but not x-reality. I unlocked my bootloader and I have x-relity enabled.
Some ROMs won't have working camera, for example: android 4.4 KitKat ported from xperia z ultra GPe, and some other ROMs.

I can see that the x-reality option is still on menu, and you can enable/disable it, but it doesn't work. Before, I could see in the first second of picture showing how x-reality improves the image (its an effect that can be seen with the naked eye), this is not happening now. By the way, its for sure that bionz stop working? How could I take pictures without it?
Thank you

Not sure about bionz, but I guessed it as I had the x-relity option enabled. I can't tell if it works or not as I don't have camera (I'm using ported 4.4)
It would be nice of someone confirmed it.
Correct me if i am wrong.
Bionz is a service which improves the pictures after a shot, isn't it ?
Bionz and X-Reality are things u can't detect that easy like "oh that effect is from X-Reality" or something else.
I thought the main reason for not working cameras on other roms was that the dev's didn't apply those 4.3 changes :S

Bionz it's a image processor that includes xperia Z1, it process the pictures taken instead the cpu. I dont know if it's easy to detect if it's working or not. But in the case of x-reallity it's very simple, when you open a picture in Sony gallery app, you can see how the picture "improves" quality in the first second. It is no so evident in all pictures, but can be detected by a naked eye, as I do.
My only doubt is about bionz processor, I already know that I loss x-reality. But I want to be SURE if bionz processing is also lost. I want to have full root (with unlocked bootloader), and have bionz enabled. I dont care x-reality or Sony apps.
Thank you very much

Not true. If you have a TA backup, install .290, unlock bootloader, install a recovery, root, reflash stock boot partition, restore TA partition, you will end up with a booting, rooted, .290 installation.

Thank you VERY much!!! Could someone tell me how to reflash boot partition only?? The TA partition which I must restore, could be restored in 290 if backups comes from 534?
Anyone please inform me the effects of unlocking bootloader. I heard that the camera doesn't functions properly after unlocking bootloader. Can anyone inform me more details about its effects.
youcan do a backup of your TA partition so in this way you will be able to do a complete restore.After unlocking the bootloader the DRM keys will loss.This affects the camera low light performance and the x-reality will stop working.it's a way to get those features work with unlocked bootloader.there it's a tutorial in sony cross development .

I heard that if I restore TA partition then it will relock bootloader. Is it true? Moreover restoring the TA partition can't give the same picture quality as it was before unlocking bootloader. thanks in advance @Anonymuszymus

Restoring the TA partition will restore you to stock ,that's including the bootloader relocking of course .if you do this way the camera will have the same performance as before you unlocked your phone.
But remember if you are not doing the TA partiton backup you will lose drm keys forever!
May I ask..

Hello buddies ,,
i have a very Bad Camera quality after Unlocking BL
and i didnt backup the ta partition
any help ?
You can relock with Flastool. It does not restore DRM keys.
Well. Next time read it more

go to the cross device development, there is a mod on how to restore the good quality without the DRM keys.
it works for me, just follow the steps as they are.
(when u need to install a kernel with recovery on laters steps, install doom kernel via fastboot using flashtool)
hope i helped.

he lost his DRM keys, SO even with a locked bootloader the camera will still be the same as with an open bootloader.
he didn't backup his DRM, so he can't restore them after locking up the bootloader, your solution doesn't help.

I guess Drm key is lost

Bla Bla....
Unfortunately, as of right now, there's no way to relock the bootloader, and your DRM keys are lost forever.
You can try the custom kernel in the ROMs.. section, which includes a DRM fix, which maybe can restore some of the functionality of the camera.

Ooo really =( so please could you suggest me
Which one should I try?
A lot sure has changed since my previous phone (Z5 compact). Back then, simply flashing stock firmware automatically relocks the bootloader.
I'm surprised that's no longer the case.
Guess we'll continue to see little to no development of this phone until major breakthroughs.

There is no way to re-lock your bootloader once you have deleted the TA partiton. There are so many warnings on your way to unlocking that tell you this repeatedly.
You can use sToRm//'s Sony Xperia XZ Premium TWRP + KERNEL + ROOT + DRM fix/restore
app to enable your DRM again, then you can take pictures and everything is as before.
