I tested this on my own Xperia S (LT26i), if you have an Xperia SL and Xperia ion this will probably work. I don't know about Xperia acro S because @DevShaft Backup-TA tool isn't confirmed if it's working on Xperia acro S (only Xperia S, SL and ion users confirmed it's working).
UPDATE 1!
@DooMLoRD is working on a Pre-Rooted ROM for LB/UB, also he's working on a CWM for LB, it's an easier way to root but requires a clean install.

Did you let the phone reboot on the steps I said was optional (maybe not optional afterall).
I did all steps and worked twice and worked.

Only if you flash someone's else TA or if you restore the TA of some device that isn't confirmed as supported.
@DevShaft 's Tool have a lot of security features to prevent the TA corruption or a fail restore.
If you want a deep discussion about it, use this topic: Backup TA for Windows

It's true that DevShaft's tool is very thorough, but fact remains that messing with the TA partition in any way is very risky.

i second that!
I WOULD HIGHLY RECOMMEND TO NOT MESS AROUND WITH TA

You are misleading people. Change Topic.. It's not Root for locked BL, but it's method to root with relocking BL. It's not same.

No. You will hard brick your device if you try.

[Read] Before Unlocking your Bootloader

It has been confirmed that unlocking the bootloader will infect and damage TA partition of Xperia M and you will lose your DRM keys forever and loose warranty too..
So it is necessary to backup your TA partition before unlocking the bootloader. After that we can always restore the TA partition and get the warranty back.
For this purpose DevShaft has created a tool that will help you backup the TA partition.So give him a thanks for his awesome work.
For more info you can check out his thread his thread
http://forum.xda-developers.com/showthread.php?t=2292598
How to??
1.Download Backup TA tool (https://github.com/DevShaft/Backup-TA/tags) thank to DevShaft after you download!!
2.Extract it and connect your device to pc normally
3.Double click and run Backup-TA.bat
4.Follow on screen procedure.
5.Do what you want backup or restore from it.
When you want to restore your TA partition make sure you are on stock kernel and rom to avoid further problems.
Good Luck
Note:Never restore TA partition from another similar or even a same model device cause it will hard brick yours.:good: Every device has its own TA partition!!!

There was another thread like this. Anyway we need to get a mod to pin either one.

[Q] Xperia SL from stock to beast :)

Hi,
I'm new and quite a newbie with android so, please bare with me
I will try to write a comprehensive guide on this during the process.
My device is XperiaSL LT26ii / Android 4.1.2 / Kernel 6.2.B.1.96 (stock, or default kernel) Rooted with bootloader locked. Busybox installed.
So the only thing I'v done after buying is rooting it.
- How to fully-backup / recovery if anything goes wrong
Before doing any operation with it I wanted to backup everything (applications, ROM, System, documents) , and I hear that there is CWM or Xrecovery for that (mentioned in some guides), nandroid, but I found different applications on Playstore and don't know which one is the right one for my device.
I understand that backing up and restoring each of these system parts requries order and probably different applications,
Can we specify here which app should I use and how it's done?
- ROM and Kernel without unlocking possibly
http://forum.xda-developers.com/showthread.php?t=2593806 it looks like possible but considering that now there is cm-11 out and not yet for "nozomi" http://download.cyanogenmod.org/?device=nozomi , I would like to try any stable, fast , light ROM out there which works for my device. Preferibly with possibility to remove any google app .
If not, how can I unlock the bootloader and do the rest?
I saw also http://forum.xda-developers.com/showthread.php?t=1617219 which looks a nice kernel.
So , what's the most adaptive ROM / kernel for my phone and how to install / flash them?
- Getting back the applications
Once it's done, how to restore back applications and data? / with what tool, without loosing anything.

Download flashtool (xda fileserver)
You can use that to unlock your bootloader
Also backbuton = volume up = BOOTLOADET MODE
Menu button = volume down =flashmode
May come in useful for unlocking your Bootloader
Also emma flashtool isnt the same as this flashtool
Also google if your not sure
If you want to know anything else then ask
Sony Xperia S was my first android
Had a nokia brick before (3310)/N95)

Thanks.
Before unlocking the bootloader , I'd like to backup everything with CWM or Xrecovery or nandroid ,
I tried installing CWM but it said my phone was not supported, so I gues I'm on the wrong place, so could you point to the right CWM?
Also, CWM I think recovers only the ROM and the kernel but no system applications, any app to do that and save everything to my PC?

As you suggested DRW Backup tool I will probably go ahead and unlock the bootloader, the only thing is now that I'm stuck at the backup point,
Before flashing the ROM or any kernel they say "backup", and it's used CWM or other tools, and when you go to install CWM they say backup first before installing...
Am I missing something here?
It's like a loop but no solution on how to backup what it's currently installing before putting any CWM or flashing a kernel...
How did you get out of this?

hey mate first of all backup ur TA partition....then unlock ur bootloaders.....then u can flash any custom kernel with CWM recovery......from recovery u can flash any custom rom or mod .zip file.....
UNLOCKING ur bootloaders voids ur warranty so always make a TA backup before unlocking.....u can search various thread for root,unlocking bootloaders,flashing custom kernel,custom roms within the thread.....
Hope this helps.....

Yep, thanks that's all clear, what I wanted to know is how to backup everything before installing any custome kernel/ROM or Recovery tool (CWM, Xrecovery, etc)..

Got it,

Basically we need SUS, we update and get the files, than we decrypt and get a perfect image of the system + we backup with PC Companion + We backup the TA partitions with TA-backup and we are ready to go

Restoring TA partition question

Hi everyone,
I have my TA partition backed up.
I've read somewhere here that if I restore TA partition it would also relock the bootloader.
Is that true?
I want to restore my TA partition, relock the bootloader, then flash a ftf (Customized USA 14.5.A.0.242 / R2D ) from XperiFirm. I would also be following this guide
http://www.xperiablog.net/2015/03/1...xperia-lollipop-using-xperifirm-and-flashtool
Click to expand...
Click to collapse
Should I restore my TA, then relock bootloader, then flash ftf?
Or I can just restore TA (that would also relock the bootloader as a i was asking above), then flash ftf?
Also, I'm on XZDualRecovery, would I lose it (which I would actually want to do) when I restore my TA? or if I flash a ftf?
Basically what I'm looking on here is to restore my phone like it was just bough from a store but with the latest stock ftf.
Thanks

- relocking the bootloader does not restore your TA
- but restoring the TA partition relocks the bootloader
- by flashing a ftf you will loose your custom recovery
to restore a phone like you bought it just do the following steps:
1. restore the TA partition
2. flash a .ftf official from Sony with flashtool
3.reboot
and you are done
