You cannot use the TA Backup of another phone to re-lock your bootloader (To restore "Bravia Engine 2" or "Download Music Info" functionality. Each phone has a different set of DRM Keys embedded in the TA partition. Using the TA Backup of another Xperia SP will hard brick your Xperia SP.
Just my 2 cents.
/\ As mentioned above; No none of us can share them. You can read a bit more about TA in this thread: http://forum.xda-developers.com/showthread.php?t=2292598

As the title says, theres a tool that to backup TA partition to save DRM keys before unlocking bootloaders and can restore it back after relock
it's in the xperia z forum but as i know the similar, it might work on our devices. only just someone could test it. i've already backup my ta file using this method but still don't know if it will work after i restore it and may cause hard brick.

All opinions are welcome.

i am also in a similar situation like you. backup your TA partition first before you unlock, to re-enable the DRM features if u wish to relock the phone. now i dunno if the sync with my gmail account alone would restore all my app data,contacts etc. so for that i also make their backup using android backup utility or pc companion from time to time.(u must know once u unlock the BL u will have the internal memory wiped )

AFAIK, TA partition is where all ur DRM keys are stored. U can backup and restore the TA partition using Backup TA utility. (search on google/xda)
Warning: don't restore another Sp's TA partition as it will hard brick your phone.

Use the search function. And if you unlock the bootloader always keep a copy of your TA partition.

as i was surfing on net i found this http://developer.sonymobile.com/2014/07/14/sonys-unlock-boot-loader-service-now-improved/ so my question is can we unlock boot loader directly without taking TA backup now ? i m non rooted device so any one please can confirm me ?
and small doubt again i was rooted device before 2 month that time i take TA backup on 4.3 kitkat after that i updated to 4.4 kitkat pure stock not even rooted now so can i use old TA backup now if i want to restore my drm keys or my 1st question is enough to solve my problem ?

DRM keys are unique for your your device no matter on which firmware you backup it.
You just need to backup it one time and that's it...

I would recommend that you take a TA partition backup if you want to unlock the bootloader, that way it is very easy to relock and restore the DRM keys.
You have always been able to unlock without taking the TA backup, but if you have done it once, then its fine, you never need to do it again
This is a copy of my TA partition for Sony Xperia ZR C5502.
Posted if anyone needed.
[WARNING] This needs modding, directly flashing would result in bricking your device.

what ta partition does
TA partition is the drm keys which activate bravia engine, clear audio, etc.
If you bootloader unlock your device these keys are lost, hence I posted it for those who unlock bootloader before backing up their TA partition.

From what I know, using someone else's TA partition would hard brick your phone. Maybe we can modify it in some way, but using it as it is might be dangerous. So it would be good if you post a warning regarding this in OP.
