If we are talking about 4.3 version, then none.
But - maybe if someone could confirm that X-Reality will stay after unlocking and using stock/stock based ROM.

Thanks for your response. I've already unlocked bootloader (Have a TA backup just in case), but I don't see any difference in the pictures. I have no idea if I still have X-Reality.
The BIONZ thing is lost after unlocking BL? Is there a way to check it?

BIONZ thing?
I'm sure if you are on stock ROM - you still have X-Reality engine on.

I never saw any difference keeping x reality on and off, so it dosnt matter to me.
Hey, if you unlock and dont see any thing strange, be happy. Dont go search for missing things
Many users saying about issues when unlock BL even on 4.3. When we will unlock BL and do not missing anything?
I think we have to wait new year when custom roms will find the way.

Things like X-Reality aren't easily replicated, otherwise they won't need to wipe the related keys. However, at certain times, I found the over-sharpening of X-Reality bothersome, and I switched it off.
Anyway, I don't see any issues with keeping my bootloader unlocked. I really don't miss anything, and I doubt most people would notice something's missing till they're told about it.

Yep, I think is not a big deal X-Reality Engine so it's true when we Unlock Bootloader on 4.3 we lose BIONZ Processing and X-Reality Engine?
If yes, what consequences we can have on device?

Honestly, my best advice is to backup TA and unlock, see for yourself, if you're not bothered by anything then you haven't lost anything you'd miss.

I will unlock now, but I already updated to 4.3 and I can't root my phone with locked BL to backup TA. I don't care about warranty, I brought the phone with intention to come on XDA an flash, so I was aware about losing warranty.
Even if I backup TA I will lose BIONZ and X-Reality anyway so backup TA to me don't make sense.
I am just worry do not lost something what I will need further time and I referring about the functionality of the device.

Downgrade to 534 and backup TA, then upgrade again. Just backup TA in any way possible.
Restoring TA relocks the bootloader and restores X-Reality and the likes.

Really? Somply using the TA. Backup program to restore relock the bootloader? No need to use flashtool or adb first?
Btw in older phones BE 2 stopped working for pictures but kept working for videos on unlocked bootloaders

I don't know of any programs, I simply use dd to backup and restore, but I'm guessing any program that does that is simply a script that uses dd.
I never saw the advantages of X-Reality in photos, only saw it in videos, and I can't see it anymore.
Restoring the TA doesn't need flashtool, adb is just to make terminal access easier and transfer the backup, technically you could just use a terminal emulator on the Play Store and upload the backup to Google Drive without using a PC. You just need to be rooted.

Restoring TA that mean restoring the phone to factory state, that mean I can't do that if I am on Custom Rom with Custom Kernel.
Factory state I will need just for warranty or I have to choose what I want, Custom Rom with Custom Kernels without X-Reality and BIONZ or Custom Rom with Stock Kernel with X-Reality and BIONZ?
What you people will do?

What is this you go on about BIONZ?
What, your camera now takes raw photos or what?
How does your camera work if your image processor supposedly doesn't?
If you manage to flash your way to a custom kernel and rom, how hard is it to go back to stock and then shove your DRM keys back in there?

BIONZ processing and X-Reality maybe do not influence much the functionality. I am just careful do not lose some pieces which I will need in the future but the only thing what people are saying is that I need the DRM for restore to stock.
Like I said, why I should go back to stock? Just for warranty, who cares! In this DRM keys is something what I have to keep?

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!

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?
Hi,
i want to unlock my bootloader, so i made a backup with Devshafts TA Backup v9.10. The backup is a 112kb big zip file and 2mb big, when i uncompress it, i made a dry run to test it, everything seems ok.
To unlock my bootloader i must send my IMEI nr. to Sony.
My Question is, do they notice that i unlocked my XSP, even after relocking it with the TA Backup, by my IMEI nr that they have?
That would mean my warranty is voided even if i relock it?
Or am i wrong at some point?
Thank you for your help!
Well you lost your warranty if you Unlock your bootloader but I've never heard or read somewere that Sony (or the repair places) are using some kind of Database to check which IMEI has been used to get an Unlock Code.
If you relock the bootloader and restore the TA partition there is no evidence of any unlock.

No Backup of the TA partition?
Well thats not smart. Why is no one reading the tutorials?
First lines of the tutorial from Doomlord:
this is the official way to unlock bootloader
if you want to keep ur DRM keys, first root device and then check this out
Warning!
This procedure will wipe the /data partition of your phone, so you will loose all ur stored data, settings. INTERNAL SDCARD will BE WIPED!!!
For Xperia™ devices released 2013 or later (for example Xperia™ Z and Xperia™ ZL), the SD card of your device will be formatted and you will lose all content (for example photos, music, videos) when you unlock the boot loader.
DRM keys WILL be lost forever

older Xperia devices sometimes got issues after unlock of bootloader (BRICK after FOTA update) - you have been warned

If i make a TA Backup, will i be good to go with rooting and all that stuff without having to worry about anything?
With a backup, will i always be able to downgrade/upgrade to any custom firmware/original firmware, and or use kernels and stuff.
Unlock/Lock Bootloader.
Can i always go back to stock phone with drm keys and lock bootloader making it 100% factory stock?
And can i have a rooted device with unlocked bootloader + the drm functions working?

The answer of all of your concerns is yes and yes you can always go to 100% factory state with your ta backed up ......
Assuming you will not mess up in flashing roms............
Are you sure? Cause what ive heard is, that you may backup your TA, but the DRM-Keys will remain forever lost.
For further information, this Thread questions the consequences of loosing DRM-Keys

Does not making a backup of TA = Backup DRM Keys.
And how can you screw up flashing roms?
Yes.
"And can i have a rooted device with unlocked bootloader + the drm functions working?"
Not sure about that, what I know if you Unlock Bootlader the DRM Keys are lost and they do not working. Anyway if you have Backup TA you can go back to Stock with functionally DRM Keys.
Downgrade to 4.2.2, root via vroot and use ta backup and you good to go. Did the same.

Wrong. If you backed up your TA partition before you FIRST unlocked your bootloader, then your DRM keys are fine within the TA backup.
Test this if you like by downgrading to 4.2.2 WITHOUT restoring TA. Your camera will not focus etc etc
Now restore TA and as if by magic, everything is fine again (though your bootloader will be relocked)
I have TA backup and locked bootloader.
If I unlock and thereby delete the TA partition, can I then restore the TA partition and still have working DRM functions while keeping the unlocked bootloader ?
No, if you restore TA partition, the bootlloader gets locked again!

You can Re-Lock your device first (just to be safe)
If you used FlashTool to unlock, simply click the unlock bootloader option and make sure the IMEI and unlock code are the same and click Re-Lock
If you did it the Sony way, you should be able to use flash tool
To get back your DRM keys simply go into the TA-Backup program http://forum.xda-developers.com/showthread.php?t=2292598 (script thing) and click on 'Restore'
If you did not make a backup of your TA keys... I am sorry... but you have no way of getting them back

Good News, you can have an unlocked bootloader with DRM functions http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672
