[Q] DRM function restore

[armmiehidetoz]

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

does you have backup your ta file before you unlock your bootloader?

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.

Yep, I'm leaving that info there for other users that want to restore their DRM keys.

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.
