Hi,
I recently got an Xperia P and was looking around to unlock it to flash custom ROMs,
soon, i realized that unlocking the phone will lose the DRM keys, so things like Track ID and bravia engine etc. will stop working and won't work even after re-locking the bootloader!
But, no worries,
You can choose anyone you want, some people even claim that they simply unlocked their devices and everything (BE, Track ID) is still working fine!
All you need to make sure is that don't flash any other device's TA!
It will BRICK you phone!
Steps
Using Backup-TA Tool:

Thanx to @DevShaft
In the meanwhile, if your phone is unlocked, you can still get the track id and bravia engine working!
There's a thread for that too, over here: http://forum.xda-developers.com/showthread.php?t=2301489
All you need to do is download the ZIP file from there and flash it via CWM!

soon, i realized that unlocking the phone will lose the DRM keys, so things like Track ID and bravia engine etc. will stop working and won't work even after re-locking the bootloader!
But, no worries, a new version of flashtool has been released that allows to back up the TA Partition so that u can keep ur DRM keys safe and unlock the bootloader,
now, whenever you feel like relocking it, just flash the TA partition back and the DRM keys will return, Track ID, bravia engine, everything will be working! :laugh:
flashtool 0.9.11.0
Added TA partition backup/restore. Using this feature, you can backup TA before unlock.
Restore TA will relock the devicee and get DRM back as well as BE2 :cyclops:
(full complete relock).
However, You cannot count on this feature if ever your device is
already unlocked. Missuse of this feature can brick the device!
In the meanwhile, when your phone is unlocked, you can still get the track id and bravia engine working!

NEVER use TA partition from other device than yours!!! It will hard brick your device!

You'll lose and get BE Back!
Yes, if you unlock the bootloader, u'll lose DRM keys and so track ID and BE won't work,
but download the zip file fix from the link i've mentioned and those things will be back!
you'll need to relock bootloader first.
Don't use any other device's TA Partition!
@dimon2242: as Kumczak said, you can't use another device's TA Partition!
Result will be a bricked device!
If you have already unlocked the bootloader, what you can do is download the zip file from here and flash it via CWM,
u'll get track ID and BE working.

Only one tip for some people who might have a similiar problem as me:
If "Advanced" menu is inactive: File -> Switch Pro.
Cheers
EDIT: @arun6106: what is the restore procedure? sorry for those questions, i need to know everything before i start unlocking BL
Great news It will propably work with Xperia Sola too, isn't it?
Do I need root, for this?

So,i just came across another, even simpler method to backup & restore TA, added in the main post, check it out guys! :silly:
I just unlocked my device(Xperia U) a couple of month ago, is it possible to relock the bootloader and drm from this link http://forum.xda-developers.com/showthread.php?t=2301489 and then backup the TA partition like your instruction?
Thank you, sorry for my bad english.

I have a feeling that my bravia engine is not working. How can i make sure that it works?
I have tried taking screenshot of a picture with turnig engine off and on and comparing pictures on pc. (Maybe picture was already good enough that Bravia didn't effect that, but i have tried a couple of them).
I had once unlocked bootloader but relocked it back. Device is Xperia P.
Any help is appreciated.

When you unlock bootloader, you lose BE, Download music Info like facilities AFAIK if you do not backup a "(somename).ta" file prior to unlocking BL..
Without taking a backup, you will not get back those facilities even after relocking.
Though there should be some possible ways in the respective thread as for my Xperia U too there's a thread to get back these features working after relocking.

You can get bravia engine etc... back after relocking...but you will have to go back to stock kernel and rom...if you want to you can follow the guide: http://forum.xda-developers.com/showthread.php?t=2301489
if you have relocked already then use this method:
1-Unlock bootloader
2-Flash stock 6.2.A.1.100 via flashtool...reboot device and let the rom settle
3-Copy the BE File (file downloaded in link above) to ur sd card
4-Root your device and install cwm
5-Now flash a custom kernel with cwm and reboot
6-Go to cwm again and flash tha BE File. do not use reboot option. Choose Power Off option in CWM(it's recommended u flash sliding and phantom)
7-Flash the stock kernel via flashtool and turn on the device
8-Turn off and flash relock ftf via flashtool
9-Power it up and enjoy again for the BE
But whenever you flash new rom...you lose BE again and need to follow same procedure....So backup is good option...Now you cannot use BE with custom rom...
Thank you so much, before relocking bootloader i flashed the 6.2.A.1.100 firmware and next i relocked bootloader, why do i need to flash a custom kernel to have bravia engine?
OK, i deleted data of Walkman apps, i went to CWM Recovery and i flashed the BE file, wiped cache and dalvik cache, bravia engine seems to work

Glad that worked for you...
In my case i had already relocked bootloader and was using custom rom...i had to follow above mentioned procedure to make BE working...custom kernel maybe for latest cwm that gives power off feature ............
Me too, i had already relocked bootloader and using stock rom, but i tried to flash that file without unlocking bootloader and it worked
Hey, I just followed the following steps and have working Bravia engine (Me thinks ) with root on a .136 C6833.
Backup TA.
unlock bootloader
1) full flash .136 ftf using flashtool. let the phone boot up and do all the initial setup.
2) Flash jackie's kernel.
3) flash update_SU 1.93.zip
4) using flashtool, flash kernel only (.136)
5) restore TA and relock bootloader
voila rooted .136 with a locked BL and working Bravia Engine
Credits to jackie099 for his kernel and DevShaft for BackupTA utility.
I didnt do any research so no credits to me :angel:
i just tried something on my phone and it worked so am posting it!!
Mods if am offending someone or violating any rules, pls notify and delete the thread!
If one hasn't already ready backed up their TA then root is required for the 1st step.

If you spread any instructions, then I ask to give references to other sources.
For example jackie's kernel. Where I shall look for it?
using flashtool, flash kernel only (.136)
NO !
If you gonna flash just a kernel your Update center will pop up notification about new system .136 system update.
So to remove that you have a choice.
-You need to remove Update center.apk.
or
You need to flash like this (everything besides "system" and "wipe app data")
This is XDA, if you cant search...
NO !
If you gonna flash just a kernel your Update center will pop up notification about new system .136 system update.
Click to expand...
Click to collapse
Where he says to flash just the kernel you already have a full .136 so i doubt updatecentre will care.
To OP congrats on finding this out (although it is semi common knowledge that it will work like that)
Just one thing, if you unlock the BL again it will cause another data format, but you can make a backup of the TA in its unlocked bootloader state and use that to unlock and thus not format data. Just make sure you have them well named.
Quick question..
To get root: I ota to 136, unlock bl, flash Jackie ric kill kernel/recovery, flash su. I wouldn't mind trying this but how is "partial root" problem avoided when using the stock non ric kill kernel that is required to relock bl?

@muntaha_v3 or @blueether ~ same question as buzman; don't you need non standard kernel to keep full root (system rw).

True, but many people only need read access to /system. May be that is the case here?
And you could always flash a unlocked backup and hot-boot a modded kernel for the odd occasion that you need full root?
Or, as I thought just after posting, a "system r/w access" start up script prior to stock kernel flash and you could also keep full root after stock kernel flash.

Sorry guys, was busy with some official Training programs so didnt have time to come online.
1) Yes you have only read access to system.
2) Restoring TA doesn't cause full wipe.
3) this i tried for some of those friends of mine who own Xperia Z1 and Z but dont exploit their full potential because they are scared they'll lose warranty. Convinced one of them, the others are still in line though. Shame on them
Not meaning to get pedantic, maybe the thread should be renamed to "unlock bl, su, relock bl" as root implies rw access to root lol (unless rw script for system is run during boot)

You will have to have an unlocked bootloader, and to save your DRM keys you will first want to do do a TA backup and that requires root. To flash the rom you only need the recovery/kernel that is packaged in the zip. you can flash that with flashtool or fastboot

The DRM keys are stored in the TA partition, this can be backed up with http://forum.xda-developers.com/showthread.php?t=2292598
The TA partition should be intact if you haven't unlocked the bootloader
Back up TA Partition:
The TA partition is the "Trim Area". There are lots of things stored in here like root certs, revoked certs, DRM keys, current firmware version,... the list goes on. What we are concerned about here is with the DRM keys. Some service centres will not service a Sony device if these are missing. Unlocking the BL will erase these.
Once you lose these keys, you can't get them back, so backup the TA and upload it to your Dropbox etc
You will need Backup TA for Sony Xperia by @DevShaft Please read the thread.
Instructions:
Download the latest version of Backup TA.
Extract the ZIP file to a folder location of your choosing.
Navigate to the folder location of Backup TA.
Make sure no other script or application which is using ADB is running.
Make sure the device is booted in normal mode (the way you normally use it).
Run Backup-TA.bat
Read the last paragraph of the license before continuing.
Read the information and follow the instructions given by the tool.

Hi baodownnow,
Perhaps you can assist me with the same problem.
I have the same 6806 model, bricked mine attempting the same flash of Lollipop from Scrubber and am trying to unbrick mine now. I have tried the C6806 FTF's using the "XperiFirm" software you mentioned and it fails in the "FlashTool" too. I have downloaded the C6833 versions of FTF from "XperiFirm" and they fail as well. Which country/carrier version of C6833 did you use to get this to work? There's several to choose from but I used the international UK version even though I'm in the USA, California area.

I used the C6806 -> US -> 108 RC4
Make sure to not extract it.
Once you're donw, downoa the latest flashtool. .9.18.4
Click on Tools ->Bundle->Fileset Decrypt
from there you should create the FTF..
after that just flash normal.

Unless there is a copy of the TA partition backup somewhere on your device you will not be able to restore it to completely stock as it is device specific. The TA partition effects some Sony proprietary functions.
Actually after typing this I remembered the 4.4.2 GPe port was available for locked Bootloaders so your TA may be intact as unlocking is what causes loss of TA.
I do not know where to find the TA backup or if there is any in the phone.

Maybe try the search function from a file explorer. If you type this *#*#7378423#*#* into the phone dialer then select service info then configuration you can check your bootloader status. Copy and paste will also work. The status will be "not allowed" if it is locked and is not unlockable "allowed" if it is locked and able to be unlocked and "unlocked" if it has been unlocked.Regardless you can return to stock but without the TA but xreality, bravia and some other things will not work. There is also a thread in the cross device section for a work around to restore those functions without TA.
did what u say and found out that the bootloader is unlock. What do i need to do now? i dont mind living without all the sony apps just wanna get update from sony. Thanks

Deleted pic as I didn't realize it Had imei number on that screen. You will need to choose an ftf from the repository and flash it with flashtool.

You are welcome. I have only used flashtool to flash kernels, but I know there is a way flash without wiping data by leaving boxes unticked.

Well ota should.install fine if it shows as available on your phone. If not you could.try finding the lollipop ftf, or see if Sony's PC Companion program will work.
Thanks alot! =)
I'm on .28 existenz Y but no matter which rom/stock i use, photo quality is terribly weak. For example, the front camera, It has a lot of noise, whatever or is sunny or is dark. The rear camera makes good pictures until you look at the details. What is wrong? You know how to correct it?
Someone also has the impression that xperia Z2 doing ugly pictures?

Here is a simple DRM restore solution:
1.flash .69 ftf
2.relock and unlock the bootloader after that
3.turn on the phone and force it off(volup+power)
4.flash .28 ftf without TA
5.flash Androplus kernel(to get recovery) and in TWRP flash the DRM restore zip
6.it should work

Those instructions worked for me and for everyone else. It has to work with your device, there is no reason it shouldn't. It also worked on my Z1.
I forgot to mention that you need to relock and unlock the bootloader after you flash .69. I updated my previous post with proper instructions.
BTW I have the device from 5 days and did it, so is can't be a problem for you.

I think not.
You must be forgetting something. Are you using .69 or other kk ftf? It must be .69 to work. Also, the relocking has to happen while on .69(in my case it didn't even boot like the original instruction said, but it worked). The .69 firmware ABSOLUTELY needs to have TA in it! Maybe that is the mistake? I can't think of other reasons.

ok, I'll do it as soon as let you know. what i want to do? i want back this DRM keys, but i want to flash existenz too, should it work?
I'm interested in this too, currently I'm on existenz with androplus kernel, but I want to get DRM back because the camera quality is really bad.
can I flash .69, then lock and unlock the bootloader, then flash the existenz rom, after the androplus kernel and after the DRM fix?
the problem that I'm facing, or at least I think it is, the existenz rom is a zip, and I need to flash a ftf, right?

3. flash .69 again
4. unlock bootloader
5. flash .28 without TA partition (check under exclude)
6. flash androplus kernel
7. drm fix
8. existenz
when still doesnt work, whatever im gonna kill myself
whoa, take it easy, the phone doesn't worth it
if it works, can you post a link to the right files to flash and how to do so, I just got my phone the other day and I don't wanna mix something up with it already.
*haven't flashed any ftf files yet, still have to figure it out how to do it.

when i check drm keys with this service menus, that says [unknown error] and [active] what does it mean?
You can restore your DRM partition using your TA.img. Just download Backup-TA from here http://forum.xda-developers.com/showthread.php?t=2292598
connect your phone with USB debugging on then open .bat file of script then select "Convert TA.IMG". At this point there must be some folder to tell your where you put your img in. After there's a backup restore by press 2.
so a simple restore is enough and no need to go through the .69 flash/DRM fix zip ? are you sure ?
My TA backup was done on 4.4.x rom, would it work normally on LP roms ?

Try this FTF
Perform these steps
1. lock bootloader using Flashtools
2. flash 17.1.A.2.69 TW with full wipe
3. reboot, check camera and x-reality - OK
4. unlock bootloader
5. reboot, check camera and x-reality - still OK
6. root, install recovery
7.Install your rom
8.Install DRM restoration zip for LOLLIPOP
9.Reboot and restore your data. (Including your SD Card)
