Hello,
I have a few questions regarding rooting, bootloader unlocking and DRM keys that I've not been able to find an answer for in this subforum.
1) I know that unlocking the bootloader will wipe the DRM keys and everything from my phone. Does rooting the Xperia T using any of the available methods also delete the DRM keys?
2) Is there any way to back up the DRM keys before I unlock the bootloader and restore them afterward?
Thank you in advance for any answers.

I had already rooted my z1 when on 4.2.2... But now the 4.3 updates removed the root... Unlocking bootloader ia only option as far as I know.. So I want to ask is..
A) if I unlock bootloader will I loose xreality engine? If yes how do I save that from not happening..
B) is there a "stable" way to install CWM recovery amd not unlock bootloader..? Is there is.. Will mybstock features be affected such as loss of xreality n DRM keys?
C) is there a way to unlock bootloader without looaing DRM keys? If so again will I loose the z1 features?
Please help..

A) if you unlock bootloader you WILL loose xreality. To get it back restore backed up TA partition. You can't have unlocked bootloader and xreality at the same time. Here is a video on how to get full root on 4.3: http://youtu.be/1aq9YTlfCgc
B) Yes you can install the recovery on any rooted Xperia Z1. You don't need an unlocked bootloader to be rooted.
Here are some more explanations if you are confused http://youtu.be/l78p_2ShPS0
C) You will always loose DRM keys when unlocking but you can back them up before unlocking to restore them later
Out there are 2 ways only how to root your Z1, both are for Locked Bootlader. 1 best way is here step by step, page 2, Post #16 http://forum.xda-developers.com/show...2588331&page=2 or NUT method here http://forum.xda-developers.com/show....php?t=2572988
..and what @shem2409 said it's all right.
So I've got myself a Sony Xperia Z1 and I'm a little unsure about how you root it.
From my understanding you need root to backup the DRM keys. but to get root apparently I need to unlock the bootloader to be able to put a certain version of the ROM on (which wipes the DRM keys).
Then I can root the phone.
Then I can backup the DRM keys
I'm seeing a loop here and I'm not sure what the first step would be. if anyone could point me in the right direction it would be heavily appreciated.

You do not need to backup the TA area (Which contains the DRM keys) if you just want to root. you only need to do that if you unlock the bootloader.
First, read this about unlocking the bootloader
http://unlockbootloader.sonymobile.com/
If you can and you want to unlock the bootloader then do so, making sure you have backed up your TA
If you cant (And in any case you must do this in order to backup your TA) you must
1) Downgrade to 4.2
2) Root using Bin4rys method, google it
3) Install dual recovery for 4.2, Its in the development thread
4) Flash a prerooted 4.4 Rom, in the development section.
If you still want to unlock the bootloader, backup the TA
Hey all,
I just bought a used Z3+ and was wondering if someone could look at the following screenshot and tell me if my DRM keys are 100% intact and my bootloader has never been unlocked. I'm having a hard time figuring it out because after the first three, all other screenshots I've found have more [Key Ok] [Active] things than mine does. but, they are also for other phones. I'm used to phones without DRM, so I want to make sure I've got everything as intended. Can anyone compare to their Z3+ who may have never unlocked it and see what they think?
Thanks for any help you can provide!
i am 100% sure your DRM key is working
Right now z3+ don't has ROOT without unlock Boot loader
That mean it can't backup TA partition and can't restore DRM key
So this phone NEVER unlock Boot loader.

Got unlocked bootloader without possible root (5.0.2 28.0.A.8.266 firmware E6533 (z3+ Dual)). Used flashtool before unlock and saved S1 Dump in Advanced menu. Is it possible to get DRM keys from S1 Dump and restore bootloader lock?
Or my DRM keys now lost... ?
Hi Guys
Quick question: Does making the only root (with Kingroot) on my Xperia Z will effect deleting DRM Keys of camera?
I am not going to unlock bootloader and install custom roms.
Thx in advance
Ps. no answer on the forum for me
no,
but unlocking bootloader does
So i read that restoring the DRM keys using Backup-TA will relock the bootloader if it was unlocked.
And unlocking the bootloaded deletes them again.
So just for confirmation: Is it not possible to have restored DRM keys and an unlocked bootloader?
Following that: Can i unlock the bootloader, flash a custom Rom, restore the DRM keys and have a custom rom + the camera algorithms? (and a locked bootloader)

No but most AOSP ROMs have now the camera as is in stock so there shouldn't be a difference,but as for stock ROM there is a DRM fix you can flash just search it up on XDA.
