No.

Rooting Xperia Z then restoring back to COMPLETE original state

Hi all,
I have a stock Xperia Z at the moment. Its a work phone.
I want to root it but because its a work phone I have to know I can go back to complete original state if I want to.
Now I have read the threads about backin up your TA partition but I am not sure if by doing this and also by having a stock image I can go back to 100% original?
I read this thread: http://forum.xda-developers.com/showthread.php?t=2234627
Few questions:
- If I root the phone - does it do anything permanent or can I then just loose root easily and go back to exactly how it is now?
- What exactly is the difference between rooting your phone and unlocking your boot loader?
- If I backup the TA partition using the steps in the thread provided above, can I then just do anything else I want to the phone and then restore back to original or are there other steps? and if so, what are they.
Any and all up to date information from someone who knows what they are talking about hugely welcomed.
More nervous than usual just because its a work phone (rooted and used to Custom ROM my HTC Sensation all the time but didn't care as it was my own phone).
Thanks

No one?

1 - Rooting only changes things on the software side. So it allows you to get complete access to the system files and execute low level actions. So it doesn't do anything on the hardware side. That said, is your phone customized by your employer? Does it have anything specifically done to it? In that case two things might happen. The software is so customized that if you root it and flash a custom ROM on top of that, you WILL lose all the original apps and settings. So there might not be anyway of getting back to the original state. Secondly, your employer might have locked the bootloader permanently. This, I shall take up for answering your next question.
2 - As I mentioned, rooting is only a software level hack that gives unrestricted access. However, let's say you need to flash a custom KERNEL or flash CyanogenMod/AOKP/AOSP (based ROMS), then it's absolutely necessary to unlock your bootloader. This basically is telling the bootloader (which loads your kernel) to allow any unsigned kernels .i.e. non-stock kernels, to be flashed on to your phone. Now mind you, this will cause the DRM keys in your phone to be erased which means you will lose Bravia Engine enhancements for your Pictures. It does remain for the videos though. Lastly, you can relock your bootloader. But you can never get back the DRM keys and hence the Bravia Engine.
So you can either root by unlocking your bootloader or by using root exploits while keeping your bootloader locked.
3 - Since your bootloader is locked right now, I suggest you use DooMlord's rooting toolkit

Also, backing up the TA partition is only necessary if you want to unlock your bootloader. This aims at backing up your DRM keys so that you can flash them back when you want to relock your bootloader. However this method is still dicey and I wouldn't recommend it considering it is a very risky method and can easily hard brick your device.
Upshot: Locked bootloader - Use Rooting toolkit. Will retain DRM keys.
Unlocked bootloader - For custom Kernels and CM Roms. Will lose DRM keys.

If you backup your TA partition, you can restore it later. This doesn't include anything other than the TA partition.
Rooting the phone just means that you have root access just like on any other linux distribution. You can fully unroot at anytime without any problems. Flashing an unrooted ROM or flashing the original ftf will remove root.
Rooting implies getting root access. You have higher privileges & apps that run as root have higher privileges. Unlocking the bootloader gives you access to protected partitions. The only real question is, do you want to use a custom kernel? - If you do, then unlock. Some ROMs, such as CM, run on custom kernels, so if you plan on using such ROMs, you need to unlock.
No, backing up TA is not enough, Follow this thread to get yourself a full ftf for your current customization that can be flashed with the official flashtool for Unlocked bootloaders or the unofficial flashtool that works with locked bootloaders. Further, you also need to relock your bootloader to fully return back to the original state.
If you aren't comfortable with doing all this, don't.
The next time you want to ask a quick question, please post in the Help Thread.
These questions are nothing new, already been answered multiple times, just adding to the clutter in the Q&A forum.

[Q] [C6603 - Telenor, SE] Bootloader unlock allowed: No

Hi,
I have a C6603 bought from Telenor in Sweden.
When I enter Service info -> Configuration, it says:
---8<---
Rooting status:
Bootloader unlock allowed: No
--->8---
I have flashed a unbranded stock rom on it and rooted it, but is there anything more I can do to unlock the bootloader?
It would be so nice to run CM on it...

No. There is no way, either officially or unofficially, to unlock your bootloader.

I guess there is not much work ongoing trying to solve this problem, right?

That is my understanding as well. Since Sony has officially provided the option to unlock the bootloader, there is not enough incentive to try to break it unofficially. Hard luck for you though as your bootloader cannot be unlocked.

Maybe someone have already begun to look at lib_get_rooting_status.so and SecGetRootingStatus() trying to figure out what is read and where it is located? Maybe that's the first step towards a solution that can change "Bootloader unlock allowed"...

I don't know much on the subject and may be totally wrong, but I gather (from reading posts by people that do know) that the rooting status (bootloader unlock status) is determined by something stored in the TA partition. The lib you mention probably just queries the correct part of the TA and displays the result.
Any attempt to edit the contents of the TA partition will end in a hard brick of the device, so this approach has probably been put to one side by anyone working on this (if anyone is actually working on it).

That might be the case. Do you remember where you got that information? I have, so far, only read that the TA partition is where DRM-keys are stored. I have also read that one should not restore a TA partition originating from another phone, or you will brick the device.

This thread - http://forum.xda-developers.com/showthread.php?t=2287016 from page 4 onwards has some good info, especially posts by Tungstwenty.
There's also another thread linked by me on page 4 of that thread with lots of applicable information.
Edit : http://forum.xda-developers.com/showthread.php?t=2234627
Just FYI before you may try it, editing any signed parts of the TA will result in a brick, not just flashing somebody else's TA. As I understand it from reading bits and pieces here and there, it's part of the chain of trust (each part is verified by the next as part of the boot process), so there's no safe way to edit it and may never be.

[Q] Unlock bootloader wipe TA partition ?

Hello.
Im abit new to the forum but here goes.
Ive read tons of posts everywhere and there aint any exact answers anywhere to find.
In the past ive never known about the TA and DRM so happy as i am i just unlocked the bootloader on all the phones and still happy. The latest phone is the Xperia Z1. It has been abit buggy to say the least but im hoping software updates will cure this.
Anyway, i rooted my phone and unlocked the bootloader on the .681 firmware and now i am on .757 firmware. Using Doomlords kernel. I thought id check if i could backup my TA partition after unlocking the bootloader. And from what ive read its suppose to be wiped when you unlock the bootloader.
Well it was no problem backing up the TA partion. All files were there and it came out with no errors. So the question, how is this possible ?
/Jonas740

No, it's been wiped, if you restore that TA you will not relock your phone and you will not get the drm keys back, it's possible because unlocking "wipe "your original ta partition and replaced it, so you have backed up a post unlocking partition, not a pre unlocking partition
Also, please post questions in the correct form

Aha, just wanted to sort things since ppl were saying that it was completely wiped when unlocking bootloader. And when I checked it wasn't.
Although, after numerous tests with the phone I can't understand what use the DRM keys is. Everything works just like it should without them.
Another question though. If I relock my phone with flashtool. What is the way to unlock it after? The official way won't work again I guess?

No it doesn't, you will need to ensure you use flashtool to re unlock. However, you will also need to make sure you have the correct folder tree
I think maybe the newest version of flashtool does this, but there are a couple of posts in DooMLoRDs thread tutorial thread in the development section about it.
The main difference I notice with an unlocked bootloader is the inability to use PCComapnion to update, but that's not a big issue for as I can create the FTF and create a flashable .zip from it....

Ye updating with Sony software won't work nor the over the air update. But that's about it as I've seen.
But I remember on my Sony Xperia V that when I relocked it, then I could use Sony update again and I did so wiping everything before I sent that one to the repair shop. They repaired it and I got it back. All under warranty
The latest update .757 is really buggy, hope they fix it. Phone restarts sometimes when using the camera.

[Q] TA and DRM keys ? Am I ready to Root ?

Quick questions and no they haven't been answered directly the way I am asking them :
1) If I wish to later do warranty repair and I currently have a locked boot-loader is backing up the TA going to give me a 1:1 undetectable root and later unroot if I choose. (i mean all my gracenote, bravia, and other DRM's be returnable to stock condition)? (if so which method is the BEST.. ? seen a couple now)
2) My stock firmware doesn't seem to be on the FTF list is this possible I have a : c6906 C6906 14.3.A.0.757 Generic CA R10 ??? This one is on the list I don't think so ? Perhaps I am reading the string from the wrong spot.. ! In which case anyone know what to do to make a backup ?
3)Everyone hates this question but I have to ask does anyone here know of a way to unlock a locked bootloader :YES flagged device; I feel like a dink asking but after sifting through hundreds of posts there seems to be contradiction as in some people eventually figure it out and/or have unlocked z1's which I have read elsewhere that every single z1 comes from factory with bootloader locked yes?
Answer one of these questions for me make my day and you will have my many thanks to come

1) Why Unlock Bootloader for Root if you can get Root on Locked Bootloader? First get Root on Locked Bootloader then Backup TA and do whatever you want. Best way is with the application to Backup TA, with that one you can Unlock and Relock, as you already had read 100 post then you know which method you have use to backup TA, right? (no? then search again) BTW, Yes, after Relock bootloader with the Backup of your TA your phone will be stock like new.
2) Perhaps you should understand that it do not matter, download any Generic CA or International CA for your specific model C6906. Done.
3)What that even supposed to mean? Type *#*#7378423#*#* and go to Configuration, if there is Bootloader Unlock Allowed: Yes, then you can unlock it, if there is NO, then is no way to Unlock it. To unlock it there is only ONE WAY, google it.

1) I think you may be confusing root and unlocking the bootloader. TA partition backups are for re-locking the bootloader, not removing root. In fact you must be rooted in order to make or restore a TA backup. Generally only an unlocked bootloader voids warranty, not root. Though if you're worried about it, you can always flash a stock FTF and you will be back to stock without root.
For TA backup there's a Windows app that will do it, just Google it. Works great
2) Your firmware is there. Google "c6906 14.3.a.0.757" and it's the first link
3) As @eclyptos said, if your service menu says unlock is allowed, then you can. If it says unlock is not allowed then you can't and I'd say there's a 99% chance you will never be able to.

almost fully clear on this but still curious how my device is R10 which I don't see on the 6906 list.. I see r4 and so on.
I have read on a website that unlike z1s and other z devices every single z1 comes from factory locked. If so then how come some people have proclaimed the unlock success? Maybe that was just misinformation?
Thanks again will properly thank everyone later at home currently using the app

Yes, it's your misinformation. All of them have Bootloader Locked from day 1, Z1S is Locked Permanently and Unlockable, Z1 is Locked but can be Unlocked from the Official Sony Web Page, just google it.

[Q] total noob here.

Hello,
I've recently (yesterday) moved from Sonyland to HTCtopia, and I have no clue about what should I do first. I spent more than a hour just to find some guides. Am I correct that all the procedures, (not counting s-off) are exactly the same as on Sony? I mean, fastboot, Kernel, rom, gapps, good to go?
And secondly - is unlocking the bootloader from HTC Dev the same as s-offimg using programs? Or are there any differences?
I'm sorry if that question was asked before. I tried to find a similar topic around here

unlocking the bootloader just allows you to flash custom recovery and roms, S-off is a whole other thing
