I have a Z2 bootloader unlocked.
I relocked by Flashtools and I don't know if x-reality backed and working. Honestly I don't know if x-reality is working now. I can't see any change between Off and X-reality of super-vivid.
just relocking can revert x-reality and other disabled stuff to factory default ?
No, you'll need to reflash a stock ftf with TA partition.

No, he needs to restore the TA backup made before unlocking the BL... reflash stock ftf wont bring his DRM keys back.

If you don't have the DRM keys, just follow the DRM function restoration instructions. Here's a link:

Exactly... That is why I gave a link to this thread. It restores DRM functions like x-reality, camera noise processing, noise cancelling without the need of the DRM keys.

I'm not sure is DRM keys deleting after the unlock bootloader. How can I know it? Because my Xperia U TrackID, Download music info was working fine after unlock bootloader. Before the unlock bootloader, I backup my TA partition via flashtool 0.9.10.1. Its like 136KB size file. Then again I backup TA partition by using flashtool 0.9.11 after the unlock bootloader. Its the same size (136KB) as before backup.
So I want to know is there way to find DRM keys deleted or not?
Sorry for Grammar mistakes & bad English.
Thank you!

How about the bravia engine? does that still work? is there a colour change when you view images on stock album app?
Wait a minute..
Yes there is a way to see if they are present. You have to go to the phones services menu by dialing ether this *#*#7378423#*#* or this *#*#197328640#*#* then Service tests -> Security then there should be something like this if they are present:
Code:
MARLIN [[COLOR="Green"]Key OK[/COLOR]][Active]
WMLA[[COLOR="Green"]Key OK[/COLOR]][Not active]
Well, at least on my xGO thats the way to see it. Thanks to taboo5200 for letting me know that.

1) Give it a try. Should work on all xperia devices.
2) Yes you can. Since xperia go got official jb update and you don't have to unlock your bootloader to install jb, there is no problem. You can backup keys with both ics and jb
3) If you unlock your bootloader you will void your warranty in any case. Backup ta partition will not make you loose bravia engine when after unlocking your bootloader you want to relock it. Won't save your warranty this mod

Thanks for your reply you have cleared all my doubts but another question if i restore the ta partition and relock bootloader i have my warranty back correct?
It doesn't matter afaik restoring ta partition to get back your warranty (maybe I am wrong though). What really does matter is relocking the bootloader.

You can be right(I'm the noob XD) but i have read if you not backup the ta partition your warranty is void. So relocking the bootloader is insuficient, you have to relock bootloader and restore the ta partition .
The tool creator said:"Backup TA can backup and restore the TA partition of the device. When you create a backup before unlocking for the first time, then you will be able to restore to full factory state (including a locked bootloader). This means all DRM keys intact, Bravia Engine working in Album and last but not least your warranty when needed":good:

I already read this thread mate, that's because I told you that I could be wrong.
Ok then, there is no reason for not trusting the tool creator. Just root and use this tool. Save and put keys in a safe folder and enjoy

This will only allow restore certain features (X-Reality, Noise cancelling etc) - It won't allow apps that require the DRM keys to be present to actually be used, so far this seems to be the Playstation/Remote Play apps.

The mod linked above doesn't relock the bootloader, it just restores some features.
If you want to relock your bootloader, you'll need to flash the original kernel. More info here: http://forum.xda-developers.com/showthread.php?p=52567280#post52567280
Search also returns quite a few threads with more info.

Nope, even after relocking the bootloader, the features you listed still require the original and unique DRM keys to function - the only real way to restore their functionality properly is either by the mod above or restoring the TA partition that held the DRM key info.

no you wont lose your DRM keys if you dont unlock bootloader, and in case you want to unlock it later you can always backup your TA partition for restoring it when you need. please see http://forum.xda-developers.com/showthread.php?t=2292598
but you definitely need root to backup your TA.
E2303, 8GB. Phone image was downgraded temporarily to root with xperiarootkit & backup TA. Latest stock image (with carrier branding due to connectivity issues without it) was (re-)installed afterwards, bootloader unlocked, TWRP installed & phone re-rooted. TA was then restored. SIM card is perma-locked to carrier. ( )
Phone is rooted, TWRP works, bootloader status is still unlocked (???), TA partition exists, but DRM features like ClearAudio+ etc. are missing from the settings. Anyone have any idea what's going/how this can be fixed? Does Backup TA not restore correctly (or worse, backup incorrectly!!! This would be VERY bad!) on the M4 Aqua?
I unlocked without backing up drm Keys and i have normally working phone with Clear Audio+...
What next features dont working u?
Normally you have to re-lock your bootloader for those DRM-related features to work again. At least that's how it was on my Xperia SP.
Can anyone tell me all DRM features on this device please?

if you did a TA backup when the Bootloader was locked and if you use the TA Backup tool to restore it, it will lock the bootloader again.
thats how it worked for me on my Xperia z and now Xperia M4 (E2363)
How did you backup and how did you restore? The restore perhaps didn't work because the TA partition has to be set to writable (via blockdev command).
This is just a guess. I didn't unlock yet but did a backup of TA (manually, not using some batch files because I don't trust them and I run Linux and Win batch files won't work).

My apologies for being a month late with this.
Flashtool provided the option to re-lock your bootloader. So, once you've restored your TA backup you can then use flashtool to re-lock.
Hope this was useful. :fingers-crossed:
Cheers,
Re-locking using flash tool only locks the bootloader but does not restore the DRM certificates.
after re-locking with flashtool you can use PCC to repair the phone and get OTA updates, but the DRM certificates are not restored, they are lost for good.
unless you have used TA Backup (http://forum.xda-developers.com/showthread.php?t=2292598) to backup the TA partition when the bootloader was locked and the certificates were all ok and valid, you need root with locked BL for this to work.
Restoring the TA partition with TA Backup tool, locks and restores the drm certs again root is required for TA restore.
i know because mine worked.
