I have an Xperia SP currently running 4.1.2 rooted, bootloader locked.
My aim is to upgrade to 4.3.3 and root, for which i will have to unlock the bootloader. To do so I need a TA partition, for which again, root is required.
So, my question is that is it okay if I take a TA Backup now [in 4.1.2] and then upgrade OTA and unlock bootloader, root and then restore the 4.1.2 TA backup onto 4.3.3 in order to restore DRM keys and Relock the bootloader?
Has anyone done this?
is it safe?
Would installing 5.0.2 stock remove the DRM keys if I flash it using Xperia flash tool and Xperifirm?
No. DRM keys geht removed if you unlock your bootloader.
Thank you! Cause no where would show me that and I didn't want to lose camera performance. Does it matter if I flash D6603 firmware on D6653?
Hi, I have a Sony Xperia Z3 D6643 (sigle-chip with TV)
I unlock bootloader with not a backup a TA partition =/ (I had make a ****)
If I restore a Stock Rom with TA partition, is it restored?
Sorry my English. I from Brazil.

No
Unless you made a backup before unlocking the bootloader you have lost your DRM keys forever.
Relocking the bootloader and Re-flashing a new ROM (even from other countries) wiping all (data, dalvik, etc) worked for me, tried this on my Xperia SP and Xperia Z2. Because the new TA partition is included on most firmwares...
Try to flash a 4.4.2 ROM (or any locked bootloader rootable), to be able to backup your new TA partition...
OR
Try this method :

Incorrect.
The DRM keys are NOT included in any FTF. If they are lost they are gone for good.
There are some methods about that partially restore some of the functions that require on DRM keys, but they are not 100% the same as having the keys
There is no point backing up the TA once you have unlocked.

I am running CyanogenMod now and need to go back to factory software (locked bootloader with the TA restored). I have got an old firmware (4,4,2 Android), but it includes the TA. I already made a TA backup myself, but what to do: flash the stock ROM with the TA and than restore my backup or should I not flash the firmwares' TA but only restore my TA?

Restore the TA and flash a stock FTF with flashtool before you reboot.
Hi
I am running Xperia Z5 (E6653) unlocked bootloader, Stock MM (32.1.A.1.185), modified stock kernel (only added SuperSU, TWRP, DRM Fix).
Is there any way I can go back to stock Lolipop (stock MM will also work).
Edit: What steps do I need to restore TA partition and relock the bootloader?

you can use flashtool to download a firmware (XF icon) and from there you can flash a stock kernel and presumably you could use the tools you used to backup your TA to restore your TA which would lock your bootloader
Hi,
My dad recentely upgrade his XZ, but it didn't work and the phone is in bootloop. So I try ti use Xperia Companion to repair it but pass 10% there is a error message and it can't go further...
So my question is can i make a factory reset using a Stock firmware with Flashtool without loosing the TA partition ? (the phone is full stock so the bootloader is lock and my dad want to keep is waranty) (I try some researches but i didnt found any answers about flashing a stock rom with flashtool, all i found is how to flash a custom rom)
Thx,
Valentin
Flashing a FTF will do nothing to the TA partition. You are safe to proceed
