I bought a Xperia X recently, and I hope to get it unlock and rooted. But it seems that unlock will erase the TA partition and lost some features permanently. So I want to know if there's a way to get temproot(such as iovyroot on z5, so I can make the partition backup).
By the way, does the backup function in the settings menu backup the application data, but not only the APKs in /data/app?

There's currently no way to back up ta keys on any of the x range as ivy root unfortunately only works on a lollipop kernel before December15 I think it is which no x range has releasing on mm, I'd love to be able to back up my xa ta keys so I can root via unlocked bootloader as doubtful there'll ever be a locked Bootloader root solution in the future alot don't seem to care about loosing ta keys due to the drm fix but I would like a way to go back to stock if the camera sucks or I need my warranty. Not sure about the Sony back up app think it's just data it backs up.

Hello guys, I want to buy this tablet, but I heard about that if you unlock the bootloader and you will lose your DRM key, so some greart function can't work. I learn that there is a tool can backup and restore the TA partition for Z3C. Is there a tool can do the same for Z4 tablet? Or is there a method can restore lost functionality on unlocked Z4 tablet? Thank you very much.
No there is no way atm to backup ta partitions on z3+/z4/Tz4 and all z5 series until a kernel exploit is found and working on this units.

Hi, thanks a lot, hoping the kernel exploit is found soon.
Just to add to this post, I am thinking of buying this tablet because I have had a good experience with pollux windy but not being able to backup and restore the ta partitions is certainly a big strike against me purchasing this tablet.
Can you please tell me if it is at all possible to root the device and install Xposed without unlocking the boot loader then?

Nope, basically what keeps me away from this tablet as well...
As I am new to the android environment, I didn't back up the DRM keys before unlock the bootloader. Is there any solution to get it back for SGP511 xperia z2 tablet wifi with marshmallows 6.0.1 and 23.5.A.0.575? Thank you so much for the guide.
NO there is no way to restore drm keys but you can get the lost drm features back http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672 but it works with my z2 idk about the z2 tablet search the thread.

Hi Hariskh,
Except Marlin, Ckb, widevine, HDCP2 unknown error shows after checking from system info. There was no error on myxperia, camera, TrackID, X-reality for mobile. Is there any others item that I missed?
So should I relock Bootloader or restore DRM keys?

Restoring drm keys using the above method will not lock your bootloader it will only restore the lost features that are lost while unlocking bootloader. Secondly why lock the bootloader there is no effect on the phone

Great. So, I will aim to restore back the DRM keys. I sent email to Sony developer teams and they replied me to post the question here. At first, I thought Emma flash tool could solve DRM issue. But, I could not even run it on my MSI windows 8.1. Why? Anyway I managed to install Emma which is not from Sony official website. Finally, I*received the error failed to set up the service for execution context.(any idea?)
All above problem started after I trying to install Cyanogen mod 12.1. Although I followed instruction from CM website, end up I got Bootloop. Then I decided to back to normal. Eventually, I only managed to install back latest marshmallows firmware by using flashtool and Xperiafirm.exe.

Mine (C5) was rooted with Kingroot and mrw.
I'd like to find out how can I backup/restore TA partition so I can use it later (probably on XA Ultra).

There is no way of backing up ta keys on any of the x range as they all come with mm out of the box. Ivyroot only works on lollipop kernels dated before Dec15 and backup ta needs root first before backing up and only upto 5.1. There's currently two options on all the x range either stay stock and keep your ta keys(which I'm currently doing not making the mistake of loosing ta keys again) or unlock the bootloader and permanently loose the ta keys to get root. Don't see it changing anytime soon either

Hi,
I'm planing to buy new phone (currently an owner of a broken Z3 compact).
My question (I can't find any sticky thread on this topic thus asking) for this phone is:
- is it possible to root and keep DRM?
- does unlocking bootloader lose DRM keys?
- does the DRM affect camera quality (for z3 compact it did)?
I also saw some thread of DRM fix (https://forum.xda-developers.com/xperia-x/development/kernel-drm-fix-nougat-t3530849). Does this mean that after aplying such a fix the DRM is back?
The thing is that I like to have custom ROM (removed all the unnecessary things thus lighter version of original firmware) while keeping all the qualities of Sony phones.; like everyone
Thanks in advance!

you could root and keep DRM, but you have to backup DRM first (before unlocking bootloader) while on marshmallow through Dirtycow exploit: https://forum.xda-developers.com/crossdevice-dev/sony/universal-dirtycow-based-ta-backup-t3514236
as you said, unlocking bootloader does wipe the TA partition (where DRM keys are stored) and worsen camera quality (irc, at the point you cannot use stock camera).
this way, before unlocking you'll have a TA partition dump you can restore anytime.
then you unlock BL, flash a custom kernel + super user with a custom recovery (likely twrp), restore TA partition and you should be done.
as for DRM Fix, i believe it's about ignoring some errors which are showed when using stock roms and an unlocked device (i.e. you cannot use stock camera and some other features).

So basically after the installation of any custom romantic I just restore TA partition (I need to do a backup prior to doing anything else).
Does this als work with custom kernel?

restoring TA partition should work no matter what the kernel is.
in fact, you could just unlock BL and restore TA partition, but it would be pointless then (i mean unlocking BL and not rooting).
a "custom" kernel is required in order to get root access

Great. Thank you.
I get he phone in 2days so until then I have to find everything.
I restored TA partition after rooting but now the phone will not boot. It displays an error about failing verification and will not boot properly. How to get around this?

YES, just backup your TA and flash kernel with DRM Fix
that's the only way

TA partition is 'something' that indeed needed by our Xperia devices which take a role keeping DRM keys, bionz image processing and others.... In short we are luckily and blessed by many devs that create method to backup TA because once we unlock bootlader it will gone forever and you can't take it back with any way including relocking bootloader
just read more from here or use SEARCH instead GOOGLE :highfive: and if you already understand what it is and/or how really important it is then I recommend this tool to backup your TA
if you don't back up the ta, you lose the sony exclusive camera functions
long story short you need flash reflash android 5.1.1 backup TA with scrpit , open Bootloader,>reinstall lastest ROM, flash boot.img >push superuser 2.7 (you can do it all with flash tool or adb terminal you need all sony drivers
i didnt do it yet with my z5c, just what i remmber from my older sony phone (i've still got warranty)
Hello
Thanks for the explanations about TA backup and one way destruction :-/ If i lost my TA partition and my DRM because I unlocked bootloader and rooted too fast in the past, the only way to get a new TA partition is to send the device back to Sony care I suppose ? (meaning phone reset + fee I suppose...)
So far the main loss with DRM is the camera feature. Can we get similar lost feature using 3rd party camera applications ?
uh... you might be able to fake a TA backup, by DRM fixing 5.1.1... check the picture guide, it's about 3 steps in
I will try it
