hi,
my name is Alessandro
i have created a backup of mine TA partition, now i want to restore it through FLASHING with flashtool.
i dont want to use the TA tool because it relocks my bootloader.
is there a possible way to restore my DRM keys without relocking the bootloader...
i can select only one unit per click....

Apart from making a TA backup is there anything else anything I should do before unlocking the bootloader. So once I have unlocked the bootloader I can get my DRM keys back simply restoring using BACKUP-TA?.
Thanks
Yes you can restore to a factory state. I'd suggest to make a full backup with a recovery of your choice as well, so you have your data etc if anything goes wrong.

Yes you can get your DRM keys by restoring the TA but it seems pointless to me just to root, backup TA, unlock bootloader, then restore TA partition
You should be aware that restoring the TA partition ALSO RELOCKS the bootloader. So if you root by unlocking the bootloader and install a custom kernel then you will loose root and get a bootloop (If you installed a custom kernel)
You can root without unlocking the boot. This keeps your TA partition and DRM keys intact
If you unlock the bootloader you can flash a custom kernel. If you then restore TA partition you will get a bootloop
Im already rooted, I just wan to install custom roms e.g. CyanogenMod 12. So you think it's just pointless to root because if I try to restore TA partition after unlocking then I can get a bootloop with a custom kernel.

No it is not pointless.
You can unlock the boot loader and install CM, but you cannot restore the TA partition and boot with a CM ROM.
If you want your DRM keys back you will have to flash a stock ROM back.
If you want my opinion I'd wait till lollipop comes out then make a decision just my thought
I have a Z5 E6633. I've read that I should back up my TA partition before I unlock the boot-loader. The Backup-Ta programme says that it needs root. To get root I need to unlock the boot-loader. If I've unlocked the boot-loader it's too late to backup the TA partition isn't it? Or am I missing something here?
Can somebody clarify this?
Thank you.

the current tool used to backup your TA uses Tempoary Root to backup the TA partition, this means you need to downgrade to a very old firmware for this work, after backing up your TA you can then upgrade back to marshmallow.
Thank you for your reply. What tools are there to backup the TA partition?
Look at this post:

I'd suggest this one
http://forum.xda-developers.com/showthread.php?t=3354307
The tool i mentioned was called ivoryroot
Sent from my E6653 using XDA-Developers mobile app
Thanks for the replies. Unfortunately I think I've messed-up. When I got my Z5 E6633 I unlocked the boot-loader with Flashtool without backing-up the TA partition. I've tried to relock the boot-loader without success. I've tried the options you've posted here to go back to stock lollipop and use ivoroot to back-up the TA and restore. It hasn't worked. Is there any way to get the locked boot-loader back?
Thank you.

There is no point for you to downgrade now as you have unlocked the boot-loader before TA backup!
Your device keys are lost forever...
you can now try this method to at least get some of DRM related features like x-reality back!

Thanks Daniel_GB. As you can see I unlocked the boot-loader without backing-up the TA partition before I got your warning in my other thread. Thanks for your patience. Live and learn
So I just got my E6653 and updated it to 32.0.A.6.152 for iovyroot compatibility, but I have a couple of questions before I proceed that I'm hoping someone can answer...
I have the following battleplan:
- Backup TA with iovyroot.
- Unlock Bootloader.
- Flash Marshmallow.
- Root.
- Restore DRM features.
1. So from what I understand, once I unlocked my bootloader I can flash any (compatible) OS to my phone?
2. Once I have flashed and rooted a Marshmallow build, if I relock the bootloader and restore the TA partition, will the root be gone? Or will I be stuck in bootloop due to DM-verity?
3. Can I just use this: http://forum.xda-developers.com/xperia-z5/development/root-automatic-repack-stock-kernel-dm-t3301605 with my DRM key instead of restoring the TA partition for full DRM-features and retain the rooted system?
Thanks.
Be sure to backup your Ta multiple times and to copy it in various devices (hdd, USB, cloud...).
Using the Sony ric off method allows you to restore your Ta if they are placed in the same folder as the tool.
This tool should also flash supersu if in the same folder. Your kernel is modified (and couldn't be booted without patching it), and allows keeping root.
I did the steps you mentioned. I now have root with Ta
Folks, I unlock the bootloader xperia d6633, now I can no longer update the device the following screen
Settings> About Phone> Software Update
I wanted to know how do I relock the bootloader, and able to upgrade to version 23.5.A.0.575
I'm a beginner, possibility ,possibility of video?
thanks
:confuso:
Edit: you can relock the bootloader without TA, there's an option in flash tool. DRM keys are still gone though
It is made clear that once you unlock the bootloader warranty is lost and many Sony software features such as those affecting camera quality are lost.
You will need to update manually with flashtool which will work fine with unlocked bootloader and is not very difficult.
http://www.flashtool.net/index.php
All this means is you need to get the firmware as an FTF file for your phone probably from here on XDA (make sure its for D6633) and then use this tool to update the phone. Google is your friend for a guide.
Edit: I probably need to tell you DO NOT try to flash a TA partition from anyone else or in flashtool (when there are tick boxes for "exclude" make sure you exclude .ta files) or you will hard brick the phone (dead as dead can be).
Ideally if you're going to unlock the bootloader you should root kitkat firmware and then take a TA partition backup to be able to restore DRM at a later time if you feel the need to.

If that means nothing to you then you didn't and you cannot re-lock the boot loader.

Even if he has no TA backup he can still relock the bootloader.

Really? I missed that bit I thought there was no way without TA
Okay I learnt something new
Don't just say it though explain how so he can do it!
(And so I can learn instead of passing wrong information again like an idiot )
Edit: found a tutorial. They explain relocking just after how to unlock
https://blog.unlockbase.com/sony-xperia-z3-unlocking-relocking-tutorial/
Unfortunately though this does not restore DRM keys (I wish though) so as said some software on stock rom won't work, but there is a flash able zip to enable most of it though
Hey guys, too much info here, I cant find what I need. How do I simply backup and root [6.0.1][D6653] Z3 - 23.5.A.1.291 ?
Thank you in advance !
If you have a TA Partition Backup you can easily unlock your bootloader, install TWRP recovery through Fastboot, install a stock rooted ROM and then Restore your previous TA Partition Backup (your bootloader will be locked again).
If you do NOT have a TA Partition Backup there are two ways: You can lose your algorithms for the camera enhancement etc etc.. OR you can downgrade to KitKat, do the Root Exploit and then upgrade to the latest FW without losing anything.
The choice's yours

Thanks, but there is no easier way to root my phone? I must unlock my bootloader? Why I need TA Partition backup? Sorry for the additional questions, but it was few good years that I didnt root my phones.
Hi,
You do not need a TA backup but it's really convenient to have. I don't know technically how it works but Sony implemented his camera, music and photo algorithms in the TA partition. If you unlock without a proper backup, you will lose these algorithms and there will be noise in the photo app. You will also lose x-reality feature and clearSound (honestly I don't remember the name).
Also, you can't restore, for example, my TA partition because each TA partition is bound to its device.
So, tell me if you care about these algorithms and we'll choose a way to proceed
Ok after your explanation, I guess I care about the algorithms. So we need to start with TA backup?

Hi,
I'm not so expert on this but I'm pretty sure that the only way you can backup TA is having a rooted Phone.
If you do not want to lose those features you need to root without unlocking the bootloader. That's because, I could be wrong, but the TA partition is part of the bootloader. So if you unlock it naturally TA will be re-written and you will lose these features..
So you need to root WITHOUT UNLOCKING THE BOOTLOADER. To do this, you need to downgrade to KitKat with the Sony Flash tools (Sony lets you flash their ROMs without troubles) and then, on 4.4, you should use the Root Exploit (it should be this but i'm not sure because I rooted two years ago, http://forum.xda-developers.com/crossdevice-dev/sony/giefroot-rooting-tool-cve-2014-4322-t3011598 ).
After that you will install TWRP Recovery, backup your TA partition using the tool on this site*, and flash the latest Sony Rom Pre-rooted.
*since you already rooted you do not need to backup the partition, but for safety purpose you should do it and put it on online storage website (Dropbox, Google Drive, etc..) and obviously on your Computer.
That's all, I advice you that you could wait someone's else explanation because I'm really no expert on this.
