Simple question to unroot phone - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi,
I make root with a method of these forum. I backup the TA partition. I need unroot the phone.
I see in the service menu that I have the option "Bootloader unlock allowed - Yes" and it works track id.
So if I would like to unroot and have the bootloader lock I understand that I only have to flash a firmware stock or maybe unroot with supersu?
Could you sure me these?
Thanks!

Thanks works

You can unlock it. But you might want to backup your TA partition first before you unlock it. If you backup your TA partition before you unlock then your DRM are not lost forever.
Try to flash dooms custom kernel, if it fails then it's lock and if it's successful then unlock

Rooting is it really worth it?

Hi I am new to super smart phones like the z1, I'm the type of person to want to hack things and make them beret but I'm also the type of person everything goes wrong for. I want to know if it really worth rooting my phone what I would gane and if it worth the risk,? Thanks

Some of the Benefits of Rooting:
1. Easily backup your apps + data to your Ext sd card (no PC required)
2. Remove bloatware (pre-installed carrier apps that you cant remove without root)
3. Full customization of your xperia z1. Examples: change your navigation bar layout, add 3 dot menu bar, customize your status bar, assign different actions to your hardware buttons, increase/decrease height of your navigation bar etc
4.Flash custom ROMs and kernels (if your bootloader unlocked)
5.Overclokking.
6.Improve Battery life with Frequencies and Governors.
7.Full access to your System phone.
8.Modified build.prop to make uncompatible, compatible apps.
9...and more...

So if I root my phone will all the stuff I have on there already stays there or does it wipe it. What happens when new updates come out? My warrenty stops to doesn't it? I would have to flash a stock rom if i have any problems? so the phones functions all work the same Ie connecting a ps3 controler? Just worry I'm going to screw it up or loose things to gain things

Unlocking bootloader might do that, but not root.
So rooting my phone will give me more control and customisation. Still keeping installed apps and game progress? Un locking bootloader will change everything and loose everything?

You don't loose anything when you root the phone.
When you unlock the bootloader than yes you will loose a few features such as Bionz and also the Xperia Throw.
Here is a video that should clarify a few things for you:

First question is what version of firmware you are on. To get a fully functional root on 4.3 firmware (with write to system ability) you need to unlock the bootloader first.
You can have a partial root on 4.3 that will still allow use of Titanium Backup or Xposed Framework. To get root you need to use Flashtool to downgrade to old 534 firmware. Than root with vroot (check out my channel for video). Than install dual recovery. Once you have root and recovery flash a prerooted rom. I would highly advise using monxdified rom.

When you go to Settings>About Phone under Build Number you will get the firmware that you are on. To root the phone you need to downgrade to .534 firmware. This place is to ask questions, but there is a search function for a reason. When you ask the same question for 100th time you just flood the forum. Your question on why you should root has been answered. If you want to find out how to do it read on the respective threads.

I did a backup of TA partition, then I updated to 4.3 (290) and unlocked bootloader in order to flash TWRP and flash SuperSu. All was nice, except for x-reality didn`t work (which i dont care so much) but I didn't know if BIONZ camera image processor stop working too.
This is my only concern. I want to know if its possible to have unlocked bootloader and root without loosing BIONZ processor. I tried restoring TA partition while unlocked/rooted, but it became in a soft-brick which I only could solve flashing a ftf.
Thank you very much!

When you unlock the bootloader you loose the DRM keys.Technologies such as X-reality Engine or Bionz will not work with bootloader unlocked.
When you restore your TA do it on the same firmware that you did the backup on. There have been issues reported when trying to restore backup from 4.2.2. on 4.3

But it's possible to have a working camera without bionz working? (such it happens in 4.3 after unlocking bootloader).
I can only do TA backup in 4.2.2 (534 or 257) because are the only rooteable versions. And I only can unlock bootloader in 4.3 because it's the only version which doesn't lose camera functionality. How it's supposed to be root and restore TA in 4.3?
Thank you.

The camera works on 4.3 when bootloader is unlocked. You are going to loose bionz and x-reality. You cannot relock the bootloader on 4.3 if you want to have a functioning root. It's either one or the other. When you restore TA you will relock the bootloader.

[Q] How to Root/UB/Backup TA with 4.3

Hi guys,
I'm kinda desperate right now. I am using 4.3 with 12.1.A.0.266 firmware.
My aim is to install CWM. For this I need an unlocked Bootloader and Root.
But all tutorials I could find are kinda contradicting themselves.
To root I need UB.
To unlock Bootloader in need to Backup TA partition.
And to backup TA partition I need root.
The tools from doomlord all require the old firmware, but silly me has already updated.
Is there any way to unlock Bootloader without root for backuping TA partition OR root with locked bootloader?
Any help is appreciated
Im afraid there isnt any root method for locked bootloader, so You must flash 4.1 using flashtool, root 4.1, backup TA, flash 4.3, unlock BL, root 4.3 and relock BL by restoring TA. The whole process just sounds hard and its complicated but follow those steps and itll be fine
Cheers

When updating to 4.3 I lose root, dont I? So there must be a way to unlock BL with no root? I think then i would lose my Drm keys, thats why i backuped them on 4.1, didn't I? And i surely can use the backup of TA i made in 4.1 for version 4.3?
Thank you for your help already!
Same, Bro

i am afraid you cant get ur DRM keys back as you didn't took a TA backup before unlocking bootloader.. :

[Q] UB already, can I still do TA backup?

I bought used Xperia Z1, and today went to service menu and noticed the bootloader is already unlocked.
This is I understand should be procedure:
TA backup > Unlock bootloader > Root > Downgrade
question is can I still do TA backup now? knowing it already came with unlocked bootloader ?
P.S.
ver - 4.3 .136
root - no, (no SuperUser seen)
DRM keys -> present
You can check DRM status

Type *#*#7378423#*#* on your phone and go to Service Test > Security, if you have [Unknown Error] instead of [Key OK] they are lost, to restore them the only way is to use Backup of your TA. If you have all [Key OK] they are OK!

simple answer is no
You have wiped your ta partition when unlocking
however, there is no need to unlock the bootloader to root, just follow the link in my signature
also, you need root to backup the TA
And I bet your bootloader is not already unlocked, they do not come like that
dial
*#*#7378423#*#*
goto service info and configuration. Post what the last line says
I bet it says
bootloader unlock allowed: yes
That means you are able to unlock it, but it is not unlocked yet
If it was unlocked it would say
Bootloader unlocked: yes

Thanks for replying I am new to Sony phones, coming from Galaxy world !!!
here is what I get in service menu for DRM keys and Unlock bootloader (attached pics)
so this is what I understand: it is unlocked bootloader,
I can root it
I can install custom roms etc.
but incase anything goes wrong, I cannot go back and install stock rom, or downgrade from 4.3 (currently) to 4.2.2 ? and claim warranty ...

yes, just flash XZDR kernel from here http://nut.xperia-files.com/
http://prntscr.com/3nnvhr
Just extract boot img, flash using fastboot, then enter recovery and flash the whole .zip to get wifi modules etc
Then flash SuperSU.zip from chainfire
http://download.chainfire.eu/420/SuperSU/UPDATE-SuperSU-v1.99.zip
then enter philz recovery, goto philz options and tick "fix root on reboot"
reboot to system and fix root.
All done.
Yes you can flash stock FTF files and yes you can downgrade, but there is no point.
You can downgrade but do take not that sometimes you lose your IMEI when skipping major downgrades for example when you're on android 4.4 and you flash a android 4.2 ftf you'll lose your IMEI. Workaround is you have to flash android 4.3 1st before android 4.2

One click unroot?

I am facing a dilemma here.
I want to root my phone (probably using towelroot)
But sometime in the future I want to return it to the exactly unrooted state.
The problem is, for that,
I must unlock bootloader
Install CWM and backup my phone in case things go wrong
Maybe install a rom.
BUT.
If I root my phone, how will I go back to exactly the old stock state, because I am creating a backup 'After' rooting?
So If I restore using CWM, the bootloader remains unlocked and still rooted?
If i want to relock bootloader, I need root.
If I want to unroot I need an unlocked bootloader.
Im so confused. Please help.
That brings me to my qn. Any one click restore to stock?
Newbie, have mercy
Why will you unroot? (Or if you don't know exactly what it means: read, read, read and ask)
You can always go back if you flash KDZ file (unroot en relock bootloader -> see thread)

I thank you for the links.
But can you clarify 1 doubt?
How To backup your phone before rooting? (Because CWM requires an unlocked bootloader. An a to unlock bootloader, I must be rooted. Isnt it a paradox?)
Or must I root before backup?

If you read the links you'll get the answer at your questions.
In any case you don't need to backup before rooting.
Just read and understand all links plus this one "Frequently Asked Questions"
forum.xda-developers.com/lg-l90/help/lg-optimus-l90-faq-t2836981
There is no danger in rooting, only the (wrong) use of root can be dangerous.
