Until a few days ago, I didn't want to do anything involving rooting with my Xperia Z just in case I messed anything up but since Towelroot came out, I went ahead and used it to root my phone without any problems but now I have some questions.
Now that I have root access on my phone, if Sony releases an OTA firmware update, does this close the root access?
My next goal with my phone is to try and cut out as much bloat as possible from my Xperia Z but I'm worried I might get rid of too much things that I might render it bricked. Is there some things I should leave well alone?
Also thinking about trying custom roms but I'm overwhelmed by all the guides so are the guides even from years ago still valid in 2014?

Updating firmware will remove root
If you remove system apps you wont get OTA
Custom roms require unlocked bootloader which will void your warranty and you wont get OTA
Look up in the forums for latest guides
OTA shouldn't remove root. Root gets removed if you flash with flashtool, sus or pcc

If you remove something wrong, just flash a ROM again. But like always said: Don't remove something, if you don't know what it is.

How to unlock bootloader for custom ROMs: http://forum.xda-developers.com/xperia-z/development/tutorial-xperia-z-zl-bootloader-t2153261
Don't forget to make a TA-Backup!: http://forum.xda-developers.com/showthread.php?t=2292598
Quote by devshaft from the TA-Backup thread:
Backup TA can backup and restore the TA partition of the device. When you create a backup before unlocking for the first time, then you will be able to restore to full factory state (including a locked bootloader). This means all DRM keys intact, Bravia Engine working in Album and last but not least your warranty when needed

Like androidtweaker1 said, unlocking the bootloader will void your warranty. The TA-Backup includes some unique data from your device(!), which will be removed for ever if you unlock your bootloader. That's why you should make a TA-Backupfirst, to keep this data.
There are 2 ways how SONY take a look at it if you unlocked the bootloader:
- They take a look in the servicemenue
- Or they take a look at if the DRM-keys(which are included in the TA-Backup) are in your device
If you relock the bootloader only, they will see in the servicemenue that it is locked. But if they take a look at the DRM keys and they aren't available, it's clear for them that you unlocked your bootloader.
If you want to send your device to a repair center, just relock the bootloader and restore the TA-Backup. There are also some threads about it, so don't be afraid to search for it. And one more thing: Never, and really never restore the TA-Backup from an other device, it will hardbrick your phone!

Hello,
I just got my new Xperia Z having used my ancient Iphone 1G for the last 4 years and I have no experience with Android and anything related to it what so ever. I've spent the last 2 days tirelessly working my way through various forums, guides, wikis to get an idea what I'm dealing with here and where to start, but there's an important decision that I could really use your thoughts and tips on.
After reading up on it, I decided I want to root my phone and this seems to be somehow connected to unlocking the bootloader and this is where I'm worried. I read the guide on how to unlock the bootloader and the warning about losing DRM Keys and the consequences of this scared me away from it. Now I'm left wondering, and this is my actual question here:
What is the difference between unlocking the bootloader and rooting my phone and simply rooting without unlocking the bootloader?
And in case the things I want to do are only available with an unlocked bootloader: how damaging is it to lose DRM keys and therefore the bravia engine and gracenote? What made you decided for or against unlocking the bootloader?
Thanks!
Hi,
maybe I can help you.
Bootloader is like the BIOS of a PC. It checks everything at start up.
Locked Bootloader only allows to run the Stock FW and in this case the DRM-Keys are working (everything is checked and safe)
Unlock the Bootloader means you were able to install an modified / other FW and then you loose the DRM-Keys (the manufacturer hasn´t checked the FW and it is in the eyes of an manufacturer "not safe". You will also loose your warranty.
If you unlock the bootloader Root is always possible as I know.
In this case the system is not from the manufacturer and unofficial modification could be done to the system. Normally all modified Systems have Root access. So you were able to do things that the manufacturer has normally not allowed. Modify system files or something like that. Also it could be possible to copy for example a downloaded and payed movie to another device. This is why you were not able to download a movie on the Play Store if you have root. On a locked bootloader the FW (system) does not give you the possibility to copy the movie to an other device and everything is "safe" (from the view of companies). No illegal copies are possible. (DRM-Keys)
Since some days Root is also possible on a locked bootloader.
The bootloader is checking the status (locked) .. then checking the FW (stock) ... DRM-Keys still valid.
But due to the root access you were also able to modify system files and apps can recognize that you have root access. So you can still use the bravia engine for example (DRM-Keys are ok). But the Google Play Store will still recognize that you have root and will not let you download movies.
This is my experience with Root ... If something is not correct, please correct me

Hi and thanks a lot for your reply, helped me understand the difference of both better!
If I only root but do not unlock my bootloader will I be able to do anything other than using custom firmware (ROMs)? Will I be able to install Apps that require root or install custom modification like the ones offered on this forum that need to be "flashed in recovery" if I only root not unlock my bootloader?
Also, still looking for some pros and cons (my second question in the original post).
Appreciate all your help!
root will give you access to recovery (in time - still in development) and you can install apps that require root access
custom mods - yes you can install them via recovery and some can be installed with root access and without recovery
if u unlock bootloader you will lose bravia engine not sure bout gracenote as i dont use it
you can check this thread http://forum.xda-developers.com/showthread.php?t=2154310 too see what have people wrote bout
rooting with unlocked bootloader
The main thing pointing me towards unlocking bootloader (I'm already rooted on locked bootloader) is being able to install kernels and major roms.
For example, you could flash Doomlords kernel and over clock the processor a bit, but you could also reduce power and save battery
The major roms I speak of are the ones that are kinda cross device: CyanogenMod and Paranoid Android to name 2. CM is based on pure android, no Sony changes so we can't flash that on locked bootloaders as it requires changing kernel. PA is same.
As for the downsides. I'm not too bothered about DRM keys. I use Spotify for music so don't think I need gracenote. Never watched a movie on my phone. BE2 isn't my cup of tea... Over saturates everything.
I'm going to look into DRM keys more tomorrow, but if someone can correct anything I've written then please do
Not being able to restore via Sony tools... Isn't that bad as you're going to be using flash tool a lot so you'll be used to that. Just keep a generic stick firmware .ftf around in case something goes horrendously wrong (usually recovery backup is enough I think).

Nice thread, I had this question too
It's my first android and I guess I should unlock the bootloader and then root, this way I won't have to wipe my data later when I decide to try cyanogenmod or something else?
Also what happens if sony release 4.2? Will I lose my bootloader unlock and root?

I would say root without unlock for now.
When you want to try cyanogenmod or others. Just backup everything using titanium backup and then u can restore after unlocking.
Rooting with a locked bootloader means sony are not aware your bootloader is unlocked

Thanks for all your replies, helped me out a ton!
I think Im gonna root without unlocking bootloader for now to get my feet wet and get a grasp of it's capabilities and limits. Can always restore the phone if I screw up and can always unlock bootloader later if I need it.

If you unlock Bootloader, you shouldn't update from Sony. Since you've (hypothetically) already unlocked, you already have 4.2 avaliable from FXP and if you really want the Sony Update maybe you could flash it via flash tool. Bootloader unlock will never be lost (until someone can create an explicit relock file, but customs roms won't relock it). Root maybe lost if you flash a rom without it but you should be able to get it back easy.
With locked bootloader, we have to wait for Sony to bring 4.2 as we can't access the kernel, but we retain the ability to use the official updates. If we're rooted and we update, we are no longer rooted and we may be unable to use the same exploit.

Hi there, ive came all the way here from the Defy turf and im really confused about flashing my new xperia z. ive tried my best reading the tutorials but it seems to be alot harder to flash the xperia z with proper backup, i mean i used to flash my Defy pretty much everyday without worrying much.
So my question is very basic.. btw I have root my xperia z through the "[Exploit by: goroh_kun & huhka_com]" method, and the bootloader is unlocked.
1. Is it possible to backup my unlocked stock Xperia Z with DRM & BE2? i know there are both twrp and cwm, but ive heard that once I "flash" my phone I will loose everything even with the SD card... (i mean when u talk about flash, there are tons of file types u can flash such as img, rar, zip etc and also tons of ways to flash, so which way to flash is the best without loosing eveything?)
And if yes, is there a step by step guide about how to use the flashtool? (i know there are million posts about what a flashtool is, but what i need is a step by step on how to install/flash cwm or twrp on an unlocked stock xperia z with DRM & BE2.) I mean I would like to be able restore if I dont like the custom roms.
2. does upgrading from the Sony update wipe out all data? i mean for the future 4.2 update can I just update without loosing from what I have at the moment (an unlocked and root stock xperia z)?
sorry to ask all these basic questions, but ive been searching alot with no clear answers...
thanks!:good:

uh bro. as soon as your bootloader is unlocked, DRM keys are GONE FOREVER. Unlocking your bootloader wipes everything too. by everything i mean your photos, music etc as well.
secondly, some updates might wipe data, and some don't

You're not confusing unlocked and unlockable are you?
The only way to unlock the bootloader that I'm aware of involves getting an unlock code emailed to you from Sony via their official unlocking website.
While the bootloader is unlocked you will not be able to update to a new official Sony ROM either OTA or via their provided PC/Mac software tools.
Locking & unlocking the bootloader is explained clearly here:
http://forum.xda-developers.com/showthread.php?t=2153261
The bootloader will be locked on all new, unopened XZs
regardless of place of purchase, a phone purchased from Sony will (should) be carrier unlocked however.

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

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
Here's the link:

Click to collapse
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.

- ROOTING and Unlock BL very difference.
Root >> i can only reach your device till system app or modified many thing in system exclude kernel. and i cant install MOD ROM that need kernel from that ROM.
Unlock BL -- U will loss DRM key your device but u can install may MOD rom or new kernell with good features. and u always can root your device with easy
About TA idk to much and only do backup here, not want to restore it coz can get Hard Bricked my device.
only that i know.... and im sorry for my poor English.

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.

Unlocking bootlader
Sorry for being a complete noon when it comes to rooting and bootloader and backups... and what not.
What exactly is at stake here? Just got my Z1 Compact today and learning from my previous devices, N7 and LG G2 (and mistakes) i kind of wanted to unlock the bootloader as soon as possible. Now i am reading all this about TA backup and loosing DRM , and feel both lost and concerned.
Should I bother with the unlock or rather wait until developers has gotten a bit further on this? Planning to use this device as a second phone for rough weather's and hopefully won't fill it up with to much DRM protected stuff (guessing that DRM is mainly for stuff bought through Sony?) so maybe I will be fine doing it later.
Any advice or suggestions are very welcome.
Cheers.

If you Unlock Bootlader you will lost your Warranty and DRM keys and like on Z1 you should lost X-Reality, Bionz Processing and Bravia engine. Losing this features will not compromise the working of your phone but DRM key definetly will compromise the warranty and if you lose them you will cannot Relock Bootloader anymore. Unlock Bootloader is needed if you want flash custom kernels like DooMlord kernel with recovery. So is recommended to Root first your phone and then Backup your TA and DRM keys so in the case you will want go back to Stock or go via Warranty you have just to Flash Stock FTF and then Relock Bootloader. But like I already said, there is no root for locked bootloader at the moment, and this is what OP was asking but he was just challenge me with Root for Unlocked Bootladers.
If sony is completely fine with us unlocking hte bootloader, as shown here: http://unlockbootloader.sonymobile.com/unlocking-boot-loader
Why did they make it so difficult to root the device?

If you can unlock the bootloader it is a very easy 2 second job to root.
But id have to downgrade my firmware. And my data would be erased. Seems so needless

That's only to back up TA upgrading with root from 4.2.2 is to 4.3 or 4.4 is not supported.
Upgrade to stock then unlock
Also I think losing all data is a sacrifice worth it besidesvyou can back up data Sony provides you with the tools or just copy SD card to desktop and restore when done.
OOORRRRRRRR.....
You can get pre-rooted firmware here http://forum.xda-developers.com/showthread.php?t=2711982
Backup TA and unlock(if you want but I'm getting the sense that you just want root)
The last option is the preferred one no downgrade pain nonsense.
And finally to answer your Question: Sony is gonna Sony they say they don't mind you unlocking boot loader but the remove the good stuff like BIONZ. Now just imagine with root in which they never claimed to not mind about.
yup owns Z1 and stuff.

As for unlocking bootloader there's no hope. But you can still get root by flashing pre-rooted firmware in the link I provided in previous post. Just follow the locked bootloader instructions.
yup owns Z1 and stuff. Also if I've helped you don't forget to hit THANKS - actions speak louder that words.
I did not thought that the first question of the OP was to root the phone ....
