I have read DRM function restoreration for UB thread and have some question . My z2 is unlock bootloader and lose Drm function like x-reality and Bionz if i follow these step
1. Relock bootloader using flashtool
2. Flash FW 17.1.A.2.69 ftf with TA partition with full wipe
3. Reboot
Is drm function will be restore? Because i didn't care about unlockbootloader and sony warranty I just want X-Reality,Vivid,and Bionz came back. and if this work can i flash 4.4.4 after.
e.g. Sorry for my bad english

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.

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

Hi guys, i have an idea. Will the idea of unlocking the bootloader and then do the root (with recovery enabled kernel that is) and then relocking (restoring the TA partition first) the bootloader work? I am a little bit confused with the fact about the DRM kind of things, since i don't want to lose it so if we could restore it back later then why this technique was never discussed? Please give me any information :angel:

Oh yeah i forgot.. this trick will not work if you haven't done TA backup wouldn't it? :-/ I have done that before so i guess this idea won't work for anybody without TA backup i guess no?

flashing the TA partition and locking the bootloader, and then flashing a stock FTF base/firmware will make your device exactly how you bought it.. It will allow x-reality to work in both movies/album, as well as track ID working.
- This technique has been discussed in previous threads.
== Do a search and you will see there is a FTF flashing guide. flashtool guide both in the android development section.
A guide on just about everything in the general section... have a look...
However even an unlocked bootloader will allow the x-reality engine to work with videos. But will stop netflicks from working. So there are probably a few apps out there that need a locked bootloader to work properly.
To have a locked bootloader you need a stock kernel. It will need to be signed, so even a boot.img or kernel.sin would be fine. Just needs to be stock.
- You could Root, backup TA partition, unlock bootloader, and then lock bootloader again. But that still uses a rooting tool.
forgive me if I'm wrong (and someone correct me) but we cant do a TA back up without root.
When I was looking into the ZU the only way to root was to unlock the bootloader then flash a new boot.img (?), this avoided vroot et al, and the issues that we seem to have atm but did mean that the first to root lost their DRM keys (TA partition) with the rooting

You can downgrade to lower firmware anytime without root, than use vroot if you don't mind some risk, than backup TA
Unless i unlock bootloader i dont need to backup TA for reflash to original ?? just needing flashtool & firmwire?
Exactly, unless you unlock your bootloader, drm keys and ta partition are not touched so you dont need to worry about them

Aah great Was thinking might reflash to stock, somthign wrong on battery maybe... :S or system reset might solve ( an app might disturb ) Will try more before Thanks m8 !
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.

Not possible to backup TA after unlocking bootloader.
U need to unlock your device bootloader first. Then find custom twrp for your device and flash that. Finally flash my kernel to fix picture issue.
