Hi everyone, wonder if you can point me in the right direction.
I'm currently on a custom rom with an unlocked bootloader and I wish to go back to stock including locking the bootloader, from what I've found out so far this is what I need to do: -
Flash original ftf
root
flash TA
reflash ftf to lose root
Now back to stock with "Bootloader Unlock Allowed: Yes"
Trouble is I can't find how to go about restoring the TA partition from my TA image so if anyone can explain what software I need and the steps I have to take I'd greatly appreciate it, thanks.
You can use the same tool that is used to backup the TA partition (read the FAQ in the 1st post):

I didn't know that you see as I used the Doomlord root exploit before the other methods were available, thanks again.
Edit: Thanks again, I'm now back to stock with the service page reporting "Bootloader Unlock Allowed: Yes"

Sorry for high-jacking this thread, it however loosely fits my problem.
When I got the Z2 I was, in all honesty quite quick with rooting and swapping the stock Sony ROM with Cyanogen. So quick in fact that I didn't bother for two seconds to actually perform a backup of the system beforehand.
So my question is this - is it possible (given the fact that DRM and such will be lost for all eternity) to revert to stock rom without the backup?
If so... How really? (couldn't find anyhone so stupid on here to do the same rookie misstake as I did so no answers was found while scouring through the forums...)
Thanks in advance, and yet again, sorry for high-jacking the thread.

you can revert to stock using flashtool and a ftf of your choice, also you can use flashtool to relock your bootloader
your drm keys wont come back
flashtool.net <flashtool im talking about

Thank you for a quick reply - forgot to add a question, what happens to the phone WITHOUT the DRM keys? What will I not be able to do - that i presently can with cyanogen or non-f***ed-up-stock-ROM?
Thanks!

nothing is affected by your drm keys weather they exist or not in 4.4.2/4.4.4 xperias they are simply used to check if you have modified your device ie. bootloader unlock (relocking doesnt restore your drm keys)

Ah, thank you!
Well as I already figured that I messed up any warranty, that's no issue for me, so really thank you. I was hoping that I could restore to original stock rom to be able to properly use the camera and noise-canceling headphones. Seems like it then. :good:

Hey guys im back after smashing my beloved xperia z (which i had mastered the ins and outs of) and reluctantly replacing it with a HTC ONE m7 which was the most terrible phone i have ever used in my life.... i have plonked a good bit of cash on a z2 and I AM LOVING IT
I had updated to the latest version of KK but i am hearing mixed reports that a root is not available for this version.
If anyone could point me in the right direction that would be fabulous.
Thank you in advance

Hello
I see you are totally green on this.
Well, im kinda green too, but I have had a lot of help from @xda and now I can manage to do some stuff with my telephone.
The first thing you have to do is BACKUP!!! This is always important.
Well, then lets get to it.
The XPERIA Z2 has a locked bootloader. This means that it cannot flash any roms, custom or other without being unlocked. When you unlock the bootloader, you delete all files on the phone, (don’t ask me how, it just does) and also deletes a partition called TA. The TA-partition contains DRM-keys, to explain that, @Envious_Data might help.
Anyway, when you have root, you can backup the TA, BEFORE you flash any custom ROM, or the ROM with ROOT. That way you will always be able to go back to scratch. Without ROOT on 4.4.4 you need to downgrade to 4.4.3, ROOT and backup the TA-partition before you even start thinking about unlocking bootloader.
(search the XDA, Google (use XDA in the end for XDA results) XDA-TV and you will find tons and tons of stuff. Once you understand some, it will come fast to you.)
I have gathered some threads here for you to read, and I hope this will work for you too.
Start off by reading this
When done, notify me.
All the best

Have had some problems with SuperSU too, but try backup ta.
If not work, try restore phone with PCC.
Then downgrade and try again.

Backup of TA was just a mention. Also its smart to have it, cuz you might forget it.

Despite all the negative feedback you've gotten by asking your question, YES there is a way. I found it and then created a new thread with the step-by-step.
Unfortunately, it does require unlocking bootloader and a few other tradeoffs such as losing X-reality and your warranty.

3 Install recovery for locked bootloader
4 Flash rooted 4.4.4 zip in recovery
5 latest firmware and root remains
I am new to Sony devices (been a Samsung guy for years). I have had my Z2 less than a fortnight but already I'm itching to root it etc, problem is it seems a lot more complicated than Samsung devices. I was always switching between roms on my S4/note 2. I am on the latest firmware and would like to root it to be able to use xposed but I'm scared of messing it up and as the phone is under warranty don't want to end up with a paper weight.
Has anyone done a detailed tutorial for newbies like myself?
Thanks in advance

It's not really that hard and there are also of resources online that can guide you.
1 Downgrade to 4.4.2 is required as noone had found a vulnerability with 4.4.4.
2 Root phone
For step 1 and 2, Have a look at this http://www.xda-developers.com/android/how-to-root-the-sony-xperia-z2-xda-developer-tv/
3 install recovery for lock bootloader
Have a look here http://forum.xda-developers.com/showthread.php?t=2785598
4 install a 4.4.4 zip through recovery. I recommend this one as its basically stock http://forum.xda-developers.com/xperia-z2/development/stock-4-4-4-23-0-1-0-167-bug-free-t2929402

It depends on how you want to root, you can root and permanently void your warrentg or you can root and keep your bootloader locked
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

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.
