hello,
i want to make a TA backup of my Device, so that i have my DRM Keys, but after reading i saw that i need Root , so now the Problem begins:
if i root i need to unlock the bootloader, if i unlock the DRM Keys are gone, as far i read this right.
so can you please help me getting them out of my ZU? I want to root to use Folder Mount and Titanium Backup.
Thank you very much .

Just follow this post..
Downgrade..
Root your device..
Then make the TA backup...
And then you unlock the Bootloader...
In this order..
that easy? thanks, was a bit scared that downgrading will make me loose the Keys
thank you very much and sorry for wasting your time. I will do it later that day.

Hi guys, i have an idea. Will the idea of unlocking the bootloader and then do the root (with recovery enabled kernel that is) and then relocking (restoring the TA partition first) the bootloader work? I am a little bit confused with the fact about the DRM kind of things, since i don't want to lose it so if we could restore it back later then why this technique was never discussed? Please give me any information :angel:

Oh yeah i forgot.. this trick will not work if you haven't done TA backup wouldn't it? :-/ I have done that before so i guess this idea won't work for anybody without TA backup i guess no?

flashing the TA partition and locking the bootloader, and then flashing a stock FTF base/firmware will make your device exactly how you bought it.. It will allow x-reality to work in both movies/album, as well as track ID working.
- This technique has been discussed in previous threads.
== Do a search and you will see there is a FTF flashing guide. flashtool guide both in the android development section.
A guide on just about everything in the general section... have a look...
However even an unlocked bootloader will allow the x-reality engine to work with videos. But will stop netflicks from working. So there are probably a few apps out there that need a locked bootloader to work properly.
To have a locked bootloader you need a stock kernel. It will need to be signed, so even a boot.img or kernel.sin would be fine. Just needs to be stock.
- You could Root, backup TA partition, unlock bootloader, and then lock bootloader again. But that still uses a rooting tool.
forgive me if I'm wrong (and someone correct me) but we cant do a TA back up without root.
When I was looking into the ZU the only way to root was to unlock the bootloader then flash a new boot.img (?), this avoided vroot et al, and the issues that we seem to have atm but did mean that the first to root lost their DRM keys (TA partition) with the rooting

You can downgrade to lower firmware anytime without root, than use vroot if you don't mind some risk, than backup TA
Hi all,
I'm getting my new Xperia Z2 (SO-03F) from DoCoMo. It's great but I cannot bear it without root.
After I Googled a ton and read many posts on xda, I finally knew these things:
1. root requires unlock (currently)
2. unlock will lose DRM keys (unless backing up them)
3. backup DRM keys needs root
So I'm falling in an infinite loop. How to root my device WITHOUT lossing DRM Keys? Maybe an root exploit should be found for us to backup TA before unlocking?
I think we should make a HOWTO guide of all the procedures, for the newbies (like me
Thx all.

For the moment, no way to root without lossing DRM Keys. Maybe an root exploit will be found to backup TA before unlocking, but we don't know it for sure and when...

Thank you for reply.
BTW, my phone shows "Bootloader Unlock Allowed: No", can I still unlock it using FlashTool?

no you wont lose your DRM keys if you dont unlock bootloader, and in case you want to unlock it later you can always backup your TA partition for restoring it when you need. please see http://forum.xda-developers.com/showthread.php?t=2292598
but you definitely need root to backup your TA.
Can anyone tell us if reflashing the stock rom over a custom rom will reinstate the LOCKED BOOTLOADER and the DRM KEYS!
Your help is always appreciated, Thanks in advance.
Will not reinstall them. After unlocking of bootloader DRM keys are gone forever. The only way to keep DRM keys is before unlocking of bootloader to make backup of TA partition.

Every thread i have been on, require us to root the device first!
So does that mean we cant backup TA Partition for DRM KEYS? As for root bootloader should be unlocked for this device.
With Lollipop phone can be rooted without unlocking of boot loader. Then you can make backup of TA partition. After backup phone can be upgraded to Marshmallow, then bootloader can be unlocked and phone rooted. In fact my phone also is rooted, I don't need DRM keys and don't make backup of TA partition. Why you need backup of DRM keys?

Thanks for such a fast response.
The reason is because i really want to root my device. But people over net sometimes complain for issues at camera(quality reduction and non functionality) after unlocking bootloader. I dont even know if these are really related. I just wanted to be ready if anything happens.
Please tell having a TA BACKUP for DRM, is that necessary or not. And TA BACKUP from my lollipop will work at my marshmallow as well ryt!
My phone is rooted and don't find any quality problem with camera or something else .
Hey guys, I apologise but I am kinda lost.
I want to unlock my bootloader but i wana backup drm keys first. To backup drm keys i need root and for root i need new recovery. So it just means I dont have a way to back up my drm keys.
Please tell me if there is anyways to back up drm keys or something I might be missing. I have been looking around for hours but i cant find a solution so I made this thread.
Some help and info would be much appreciated.
