Hello. My question is how to make a backup TA without root Because I want to unlock the bootloader and wants to make a backup of the keys DRM
Sry for my bad english
I know one way, its wait for pre rooted firmware . I mean you flash it as normal firmware, but it will rooted and you do backup.

As far as I'm aware, the only way as of current to root the M4 Aqua is through unlocking the bootloader. Thus losing the DRM keys (even if a pre-rooted firmware is flashed).
You would have to wait for a root method to become available for locked bootloader, to be able to back up DRM keys and flash a pre-rooted firmware through recovery (unless Sony has bundled in a working recovery now, which I don't think they have).
Try this to root your phone with Locked BL.

I have a E2363, i flashed 26.1.B.1.85 firmware and was able to root and take a back up of the TA partition.

Before you do anything backup the "TA" partition or you will lose the Sony DRM keys. For more info Google "Sony DRM backup TA".
Then follow the instructions here
I have a Z Ultra GPe running 4.4.4 stock everything never wanted to root until the latest 4.4.4 OTA due to the low speaker volume, I can barely hear the phone ring anymore, I see there is a volume fix but that requires root and that's what I want to do; root.
As far as I understand and please correct me if I'm wrong, there are two ways to root :
1. Unlock bootloader, install dual recovery, change kernel, root.
2. Use towelroot apk to root the phone without modifying bootloader, recovery or kernel
I have seen that many people are facing camera problems when using method 1 due to unlocking the bootloader in addition to not receiving OTA updates after using method 1 (can't wait for Android L OTA)
If I root using method 2 will I avoid facing any camera problems and still receive OTA updates?
If there is another method I don't know about to fix the low volume issue or root my GPe please let me know, most important thing is that my camera is not affected and I continue to receive OTA updates.

Method 2 is the best way now that we have a root exploit. It wont modify the kernel/boot loader etc so should allow OTAs. As this is not unlocking the BL it shouldn't effect the camera (it is only 4.4.4 that this happened on), and you can back up the TA if you do ever want to unlock the BL. I would do a backup of the TA anyway as it will give you an easy root method should there not be one available on 5.0
in short: should work
Can you please elaborate, I don't know what TA is and why or how to back it up?!

TA - Trim Area, It is where the DRM keys and other things are kept. It looks like this is what is breaking the camera in 4.4.4 with an unlocked BL. If you back up the TA you can restore it and thus relock the bootloader. There is a tool called TA backup linked in one of the stickies in the general section.
If in the future you cant get root to do a TA backup it would be handy to already have one. Then you can unlock the BL, flash supersu, restore TA and have a rooted phone with locked BL (and intact DRM keys)
Thanks, will back up TA and root using towelroot

Sorry this may seem like a stupid question but I want to understand how this works;
If I root my device using the Towelroot exploit and my bootloader is locked and recovery and kernel are stock, will my TA or DRM keys be affected!?
I surely will backup my TA like you advised but I just wanna make sure I understand how it works as I am coming from a Samsung and HTC background so this is all new to me.
and one last question please (sorry for asking so many questions)
Do I root first then backup, or do I backup then root?

You have it right, your TA (hence DRM keys) won't be affected by the root process.
Root then back up the TA partition. You need root to pull the disk image off the phone, that's why GPe users that unlocked/rooted before towelroot are in the position with a buggered camera that seems to be looking for DRM keys.
Thnx again!
This is a bit off topic but will we get an android L update at all now that the z ultra gpe has been pulled from the play store
People are saying that it has reached End of Life!!!!!!!!!!!!!!!!!!!!!!!

Z Ultra Gpe released on Dec 13 2013. According to Google Gpe devices "traditionally" are updated for "about" 18 months. There is speculation that Gpe program may be winding down in favor of the "Silver" program. I would expect to see it updated to L but there are no guarantees.
google would be hurting their brand if they pulled updates after only 8 months. Would you buy another google branded phone if they did that, be it GPe or Silver? This is why I cant see them not supporting well in to L
Agree with blueether, Google will probably update the ZU GPE to Android L, but that may be the end of the updates we get

Yes, flashing new (unrooted) firmware will always overwrite root, but you can follow these root instructions to root .314.
yes you will but can get it back

yes you will loose root but you should be able to root it again
personally i do have Xperia Z2 everything factory installed (rooted) 17.1.2.A.0.314
i updated it with sony PC Companion and rooted it again with EasyRootTool v12.1 after 1st unsuccessful attempt with Chinese dev's root tool.(when i say unsuccessful that doesn't mean the tool is unsuccessful i probably wasn't using it the way i should)
latest easyroottool is here (new version of the one i have used to root updated Z2)
http://forum.xda-developers.com/showthread.php?t=2784900
chinese dev's tool is here in case you need it (or find latest version if there is any probably wont need it)
http://forum.xda-developers.com/showthread.php?t=2559009
before you wanna go ahead i would say research a bit more if you feel like it. personally i wasn't very careful cause i got DRM Keys backup thanx to devs but i got it done with EasyRootTool V12.1 in 2nd attempt.
goodluck
You'll only need to back up TA (where DRM keys are located) if you unlock your bootloader. Also, you only need to unlock your bootloader if you are flashing a custom kernel or Rom that requires a custom kernel. If you are only wanting root, there is no need to back up your TA partition. So just use the Easyroot tool to root after updating to .314 via PC companion if you are using that method m8:good:

Hey Guys,
So I just bought a Z2 with Android 4.4.4, and after a lot of reading I understood that there is no "one click" rooting option for it and that I have to downgrade first and then flash a rooted ROM.
The thing is I checked all the the current threads and they are somewhat very hard to follow through and a little bit made to advanced users
Topics like: http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155
So sometimes midway they skip a step or dont explain how did they reach there (specially after step 9 in the above tutorial)
I know I am asking too much, but will someone walk me through how to root my locked boot loader phone ?
FW: 23.0.1.a0.167
Thank you very much
There are 2 ways to root
Safe way which is this way which includes downgrading and having to reset your device twice
Or the easy way which is unlocking your bootloader (losing your TA and DRM Dependant features) flashing a custom kernel + recovery
You cant root at all without losing data
Hi mate
I suggest you to try this method first
http://forum.xda-developers.com/crossdevice-dev/sony/giefroot-rooting-tool-cve-2014-4322-t3011598
It doesn't work for me and if it doesn't work for you too we can talk to the author to support our devices

Hey Mate , Thank you for your reply
I have tried it but it didnt work, it says my "phone isnt vunerable", I have sent to author waiting his reply.
If you have any other pointers for me that would be great !

I have also the same error now we are sure that our devices are not supported yet I think he needs some informations about the kernel.
I sent him message and I got a reply but he thought that I have 4.4.2.
He told me that he is busy.
I sent another message and I'm waiting his reply.

Then How to do it even with losing data, but not losing the original FTF ?

Its not too complicated, but im sure its 100% safe. The step only required downgrade and then install the pre-rooted rom. If you know how to flash with flashtool, then this is not a big problem. Before you begin, please make sure you understand each step that you gonna do. This is how actually i do.
1. Download all files required(ftf, rooting tools, prf creator, recovery, etc)
2. Make the pre-rooted rom first.(i just skip that step 11)
3. Flash the stock .314
4. Root & recovery it.
5. Insert that pre-rooted ftf that i made early, in my case i also use a stock rom .167
6. Reboot and finish.
I've rooted Xperia Z before and I'm sure it was much easier. I'd like to root my Z2 but it's much more complicated. I mean I know how to use flash tools, but I'm a bit lost when it comes to drm keys. Is it possible to root and unroot if needed so Sony won't know if anything goes wrong ? Does your method involve drm backup?

Yes rooting doesn't Unlock your bootloader so no loss of DRM keys. Its theoretically impossible to hard brick a locked boot loader Z2.
hi guys im new to rooting and xda

hwlp me out fellas............
Downgrade your firmware to lollipop and root it without unlocking bootloader (because it is possible on lollipop). Then do a backup and after you backed it up flash marshmallow firmware back and unlock it and root again.
