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

The tool i mentioned was called ivoryroot

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

Hii .. just a quick question_do i need to restore my TA backup to completely unroot my phone for the new update ?
Sent from my C2104 using Tapatalk
In most cases, you'll need a locked bootloader (restoring TA backup to do so). When updating you'll lose root.

thanks for replying .. okey i'll lock my bootloader again_
here is what i will do .. i'll install the ftf again and then restore the TA backup , this will do for the sony companion app to recognize my phone .. won't it ?
If you are updating your phone via flashtool, You wont need a locked bootloader.
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
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.
Root here (other methods available, but I like this way):

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

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
Hi all!
I have my Xperia M2 with the latest firmware: 18.6.A.0.182.
I want to root it, and install a custom recovery, and i know how to do all of this through this forum. But I need to unloock my bootloader.
What's the problem?
If you go here: (i can not post links, the developer sony / unlockbootloader) and warns you:
Important note! In order to unlock your Xperia™ M2 you need to be on software version 18.3.C.0.37. Also beware that booting this device the first time after unlocking the boot loader may take a long time.

I don't know why this...
Searching in google, the people recomends to use flashtool to unlock the bootloader.
What will happen if i intend to unlock it and something goes wrong? I don't know how to solve a soft-brick withouth an unlocked bootloader.
Thanks for your help.
Hey, first do it the official sony way flashtools doesn't work for many including me when i unlocked my bootloader. http://developer.sonymobile.com/unlockbootloader/unlock-yourboot-loader/
Second if anything goes wrong, just reflash your firmware (jellybean, kitkat, lollipop whatever) through flashtools and it will be back to stock.
Unlocking your bootloader there is not much which can go wrong.
Btw, you will lose your DRM keys. 2 of them i think for buying stuff through ps store.
Also if you run into problems post here we'll help.
Now I have root with KingRoot. If I make a backup of TA partition i can restore DRM keys when I like it, no?
And the magic question for me is: How I flash original firmwares if the bootloader is locked? I only need locate the right FTF and with flashtool is enought?
Thank you!

Yes you can restore your DRM keys backup if you want in the future.
And if you want to flash a FTF on locked bootloader you can use Flashtool by Androxyde or Xperia Companion.
Ok, thank you all, I'll try to backup DRM keys and unlook the bootloader and I'll post the results!

Hi there,
I know this post is related to another user but I wish to relock my bootloader for another reason and was wondering if you could help me please?
I have TA backups, and what I am trying to do is to restore the DRM keys via the RootKernel tool; however, everytime I flash it via FlashTool, I can never figure out if it worked or not?
Could you tell me if there's a way to check if the DRM keys have been restored on an UNLOCKED bootloader please?
Also, can you tell me how to relock the bootloader, as well as restoring the original TA so everything works fine again please??
Thank you for your help
==========================================================================
Edit: I've found out how to relock the bootloader and restore TA, but I still don't quite know how to check if the keys are installed when on UB?
got the same problem as OP. anyone know how to get camera work with lock BL and stock FW.???

The same problem here, I've re-locked the phone and installed the stock Nougat ROM using Sony's PC companion, so no TA backup and after that every time I open the camera, it says ''Error: the camera may be in use by another application. please close the other application and try again.'' It's also the same for developmental Marshmallow ROM that I've installed by EMMA and even with the boot-loader unlocked the camera quality is really poor and doesn't save the picture it takes. So have I messed up the DRM security keys as part of boot-loader ? How can I fix this ??
I found this in Sony's developer site:
''Once you have unlocked the boot loader, you will not be able to revert the device back to a locked or original state or restore the DRM security keys.''

May I borrow your TA back up and DRM keys for my F8331 ?
Dont use someone else's TA Partition. It ain't going to work.
Why don't you simple re-open your BL and flash a Stock ROM ? What is the benefit of re-locking if you lost your TA Partition ?
Picture quality is the same as stock unlocked if you flash androplus kernel

WARNING!
using another one's ta partition in your phone will hard brick it. Each xperia has it's unique ta as an identification for the chip. Do not ever think about that.
