[Q] [HELP] Question about C6502 4.4.2 Root

I just updated my sony xperia zl C6502 with the 4.4.2 stock update. My phone was rooted but not anymore after the update. Is there anyway to root it without downgrading.

if you have backed up your ta partition before, then proceed with the following steps
unlock bootloader
flash any xperia zl kernel which has custom recovery like CWM in it. for example, this one ==> http://forum.xda-developers.com/showthread.php?t=2191264 (though it's meant for older firmware, the recovery works but the phone wont boot to system)
enter into recovery and flash the supersu zip
then switch off the phone in custom recovery itself. (because the phone wont boot to system)
then flash back stock kernel and you have root :good:

u can get root access now but u have to unlock your bootloader. and you can't relock it unless you have the TA partition backup.
to get it, you have to flash back old firmware to gain root. backup TA partition so that you can relock bootloader. and in the future you dont' have to downgrade again to root

Is there a tutorial on how to downgrade? Once I downgrade I can use nuts method?

yeah. just flash an older rootable firmware(10.3.A.0.423) using flashtool. root it using doomlord's rooting kit. take a backup of TA partition using devshaft's backup-ta kit. this back up of TA is just to relock your bootloader whenever you unlock it because unlocking BL voids warranty. but the backup of TA partition must be taken in locked BL condition. flash nut's dual recovery. now follow the steps in the link posted above and upgrade to 4.4.2. this method doesn't need your BL to be unlocked.
there is another easy method which requires unlocking BL. but you can relock it as if you never unlocked. i prefer this method. the link is posted below.

[Q] Update Android from 4.1.2

Hello my friends.
I'm the owner of the Xperia S with awful interface. I know that Sony not going to release the next update of firmware, so I have a question for you. I'd like to have Android 4.4.2 or although 4.3.
I know that i have to Unlock Bootloader that I have to flash my device but unfortunately i have this option locked (attachment). My question is: is there any way to update my Android without bricking my phone?
I will be grateful for any help

No. You're stuck with Sony's 4.1.2, or maybe CM9, of you want.

There is a old Cyanogenmod ROM for locked bootloader:
http://forum.xda-developers.com/showthread.php?t=2593806
Read carefully, I didn't test it and of course there is always a chance to brick your Phone!

Thank you so much for this link. But i don't understand how I can flash it to my phone. Can someone explain this for me in step by step guide?
I used to flash phone once long time ago my SE k800i and it was a way easier than this, just connect phone and overwrite 2files. This process is more complicated and I could use some help.

Sorry i have unlocked bootloader, so I can just take a look for you...
I thought you could just flash it via Recovery (like in this video http://www.youtube.com/watch?v=UvD6ZCENlJA with the option apply update from external storage or so...)
If that is not working you can try this:

Just search for DooMLoRD

Thank you for helping me.
I decided to use first option - install it via Recovery. But there is a problem - Xperia S doesn't have pre-installed recovery. So If I want to do this I need to install custom recovery. But I need root my phone to do this. I could use Doomlord method but it is only for 6.2.B.1.96 firmware, unfortunately I have 6.2.B.0.200.
I know the steps that I have to do:
1. Root my phone.
2. Install custom recovery
3. Flash ROM via Recovery.
But I can't root my phone because of firmware. What now?
@edit:
I found this link http://forum.xda-developers.com/showthread.php?t=2327473
It was tested on Xperia S (LT26i) {FW: 6.2.B.0.200} [v16 onwards] and it "WILL WORK on both LOCKED & UNLOCKED BOOTLOADER".
Is it right solution for my problem?

Towel root. Rooting won't erase anything from your phone

Towel works great but not if you've already upgraded to 4.4.4.

Is your bootloaded locked, or unlocked? For LOCKED bootloader, I used the following procedure multiple times with no problems (I don't see why it wouldn't work for unlocked bootloader, but I haven't tried it):
1. Flash .230 kernel using FlashTool (basically, you are temporarily downgrading your kernel).
2. Root your phone using newroot.
3. Flash either .283 or .292 kernel (whichever 4.4.4 build you are on) using FlashTool.
4. (optional) Flash a custom recovery (I use XZDualRecovery by [NUT]
You will need kernels to flash in steps #1 and #3 - either search for FTF files to download, or create FTFs yourself using XperiFirm checker/downloaded and FlashTool. The procedure for creating FTF is described in XperiFirm thread.
There may be other ways; I am only telling you what I tried myself, and know 100% that it works...

The way I understand it, the method I described should also work for unlocked BL.
Of course, you don't need to flash a new ROM -- just a kernel. That's exactly what I said... First, downgrade your existing kernel for rooting, and then, after the rooting is done, flash the proper kernel back.

I wanna root my phone , with locked bl. May I know which website to follow??

@akandi
1) First go unlock your Bootloader Here ( Official Sony Website )
2) Download the Latest SuperSU Zip File
3) Download any Custom Kernel ( For Lollipop Of Course ) found in the Android Development Section, or you can use the boot.img kernel found in any CM 12 Rom
4) Flash the kernel on your Z1 Compact via Flashtool and enter recovery and flash the Latest SuperSU Zip File.
5) DO NOT REBOOT! Power Down and open Flashtool
6) Select the .270 FW and Uncheck All Except Kernel and FOTA ( Uncheck Final Verification ) here we reflash the stock kernel since using the CM kernel on Stock ROM would cause a bootloop
7) Flash and reboot
or
Install Kingroot on your Computer, root your phone and once your phone receives root access install NUT's Dual Recovery, after which uninstall the Kingroot Superuser app and use SuperSU instead since its less buggy and more stable.
With the first method, once your bootloader is unlocked it is very easy to root your device even when Sony updates it. Personally I used the first method to root my phone

Does the second method unlock my bootloader?

[Q] Rooting

Hello.
At the moment I am using stock lollipop .270.
How do I root it in order to backup the TA partition ?

Probably you have to flash KK v108 with Flashtool, root that and flash an already rooted+recovery 270 that are in the general section of the forum.
Or check around general forum if you can root without going back (been out of the loop with rooting procedures). Something like this thread http://forum.xda-developers.com/showthread.php?t=3140241

So if I use Flashtool I guess I have to onlock bootloader. Wouldn't that destroy the TA partition ? I want to backup it before I begin modifing anything.

I rooted just a few days ago while on the 270 uk firmware. Unlock bootloader first then i auto rooted with chinese Kingroot app http://androidxda.com/download-kingroot-application . After this i follwed ( http://www.w0lfdroid.com/2015/05/How-to-Remove-Replace-KingUser-KingRoot-with-SuperSU.html ) this guide to remove kingroot and install super su. After this i used ( http://nut.xperia-files.com/ ) Th locked dual recovery from here which installed the recovery to the phone. Next step is here https://www.androidfilehost.com/?fid=23991606952609257 . Once you flash this prerooted firmware you are fully rooted. good luck i hope this isnt too confusing.
Note iff you do not unlock bootloader the kingroot app will not be able to root the phone. bootloader unlock is the first step.

For flashing a ftf via flashtool, You don't need to unlock bootloader. You could also try the link from My signature to root, it worked fine for Me on locked bootloader.
