[Q] Confusion on TA Partition backup with the latest stock firmware

Hello!
I have searched various places about rooting my SP. I am about to root my SP, it was newly bought (2 months old) so it would be better if the TA Partition is backed up. After inspecting several articles and stuffs, I was advised to back up my TA Partition before attempting to root my phone.
As of 12.1.A.0.266 update, rooting requires unlocking the bootloader. Which doesn't follow the rule to back up the TA Partition. As one may know, a phone must be rooted in order to back up the TA partition but at the same time, such bootloader must not be unlocked
I've searched everywhere I can, however I can't find any solution. Forgive me if there are any articles or thread created regarding the same topic.
Any immediate help would be extremely appreciated.
The phone is running latest stock firmware and had no customisations so far.

Use a pre-rooted rom (PureXSP, eXistenZ)...Not sure if it will work!Don't try unless a person with higher android knowledge skills answers!

How about you just FTF flash an older firmware?

flashing ftf won't require unlocked bootloader isn't it? I do thought of downgrading then root and then backup such TA partition.

No it wont.
For the Sony features like Bravia Engine etc you need the TA partition. Flashtool will (or should) work without the TA partition. It will only tell you that your bootloader is unlocked

I was in the exactly the same position as you few days ago when I decided to customize my Xperia SP
Here is what I have done...
I was on the latest .266 OTA updated FW and then ... ...
I downloaded and flashed with Flashtool "Xperia SP (C5303)_12.0.A.2.254_Generic_DE.with_loader.sin.ftf"
Then flash XperiaSP_C530X_12.0.A.1.257_KernelOnly.ftf
Now you can use DooMLoRD_Easy-Rooting-Toolkit_v18_perf-event-exploit.zip
and then flash back XperiaSP_C530X_12.0.A.2.254_KernelOnly.ftf for your current FW
Now that you have rooted your phone you can use Backup-TA-9.10 tool to backup your TA partition and save your precious DRM keys
And when you have your TA partition backup safely archived somewhere
you can go to Sony site to request code for unlocking bootloader.
When your bootloader is unlocked use FASTBOOT to flash any kernel that have custom recovery
(like Nayak03 or DoomLord's V05 or DoomLord's advanced STD .266)
and then when you have custom recovery you can install pretty much everything you find around here.
If you need more details or want me to put links to threads and files I've looked and download just say... :cyclops:

It is not about Flashing, it is warranty.. My phone is 2 months old and there are 8 more months for valid warranty.

Wohoo thanks! Yes, I do thought of the same way, however, I am looking forward to use the stock sony .266 FW after rooting the older 254. Any tutorial you can give here or any links I can get on how to actually "install" the .266 firmware?
Yes I do would like some links on downloading those stuff except Flashtool, I did have it already. If you don't mind posting them..
By the way, since I see that .266 FWs have different versions for each region on this world respectively, may I know how to get one that is international or south-east asia specific?

some links that might help you.. (links for downloading stuff in there...)

1 downgrade FW to 12.0.A.2.254 (or 245) DOWNLOAD HERE
2 change to rootable kernel 12.0.A.1.257 DOWNLOAD HERE
3 use DoomLords perf_exploit rooting script DOWNLOAD HERE
4 flash back kernel only 12.0.A.2.254 DOWNLOAD HERE
5 start your phone and start TABackup HERE
6 go to Sony site for an unlock code as explained HERE
for which you use Fastboot HERE
7 again with fastboot flash kernel with custom recovery like THIS one DoomKernel AdvStd .266
8 reboot to recovery while presing VOL+ key when lightshow starts and install CustomROM of your choice which you downloaded previously and put it on your microSD card.
OR if you want stock rooted FW
in step 7 first flash official .266 FW then fastboot DoomLords .266 AdvStd kernel
boot to recovery and from it root your system

Thank you @mrhnet and @freedom74 !
You guys really solved my questions in a quick manner of time!
I just registered xda just to ask this question and I received a really good help.
I will read both posts and see what I can come up with my SP. I can't wait to root it! Again thank you, guys!
I hope nothing bad happens, this is my only phone and it costs so much
:victory: thanks again!

lol I am sorry I am back. I am having difficulties on finding appropriate firmware.
Hey I saw a post saying that it ripped firmwares from the SUS. Do you know how to do this, so that I can have the version right for my country?

[Q] Root Android 4.4.2

Hi.
I bought a New Sony Xperia Z1 that came with Android 4.4.2 KitKat installed.I have been trying to find a way to root the phone in order to install SDFix to remove the External SD card limitation (if there is any other way to remove the limitation please let me know). My problem is that I have followed instructions as to how to do the downgrade to root and still have no good results (Newbie here) or only see posts for devices that were previously rooted or had JB installed . Can someone guide me in the right direction please?

Both questions are answered in my original post
dual recovery is in the cross development thread.
You do not need root to install it, it will install CMW, Philz and TWRP recovery...

[Q] Point me in the right direction...??

Hi there guys!
I want to root my Z1 c6906, unlock the bootloader and flash custom roms, but im kind of confused right now because i have read a lot of different guides and im not pretty sure which one to follow now. I also learned on one thread that i should do a TA and DRM Keys backup because they can be lost forever if i don't do a backup. Also the IMEI. So im not pretty sure how to do that. Also saw a thread about bricking the device, and kind of got scared. Btw, i have plenty of experience working on Android devices, unlocking, rooting, flashing roms, etc. I have used Android since the G1, but im kind of confused right now about how to proceed on this device because this is my first Sony and my last phone was a Nexus 4, which was virtually unbrickable. Can anyone help me out here?

Quite simple process actually, just flash .534 ftf with flashtool and root with bin4ry or use nuts dual recovery installer. To backup your ta before unlocking bootloader, simply use the Backup TA tool

Sorry for bringing back this thread. Now i got time to start trying to unlock the phone and flash custom roms, was extremely busy before with work.
New problem: After i downgraded to FTF .534, rooted and made the TA Backup, i check if the phone was "allowed" to be unlocked and surprise, it says it can't be unlocked. Tried unlocking with Flashtool and it said the same thing. Can the phone be unlocked or is there a way to flash roms without unlocking?
Right now im feeling really depressed with this phone. If i can't unlock it, i most likely will sell it and get something that can be unlocked.
One of the reasons i want to unlock is because on 4.4, Google prohibited the phone to write on the Ext.SD and i want a way to overcome that prohibition and use it like i was able to on 4.3.

If it says it cannot be unlocked then it cannot be unlocked
However, you can still sort out the issue of writing to the ext SDcard by rooting and following the instructions in this thread
http://forum.xda-developers.com/showthread.php?t=2687966
In order to do that, you only need root, not to be unlocked

Ok. That sucks. Thanks for the link.
Another question: How i root.757? I was able to root .534, but not sure how i need to proceed now. Do i need to download generic .757 and apply any root method? Or the root will still be there if i flash it over my current rooted .534?

1) Flash a stock 534 FTF (Ignore if you are already on 534)
2) Install dual recovery (Find files and instructions in the XZ dual recovery thread in the cross device development section)
3) Flash a prerooted 757 rom (Find files and instructions in the development section)
Done, 3 easy steps

So i can flash any rom now with that recovery? Even if my bootloader is still unlocked? Or only stock based roms?

If your bootloader is unlocked you can flash any rom from the development sections or the original development section
But if your bootloader is unlocked you do not need to do any of this to root.
Just flash DooMKerneL or [NUT]s XZDR kernel
If your bootloader is locked, you have to downgrade and root that way. Then you can flash any stock based rom, look in the development section for them

There is no such thing as a stock recovery on sony phones
You will just need to flash a FTF file, but you do not lose warrenty by rooting

Hey gregbradley,
So, I used to be a Samsung user, but now I moved to Sony. I got a Z1, which is currently running KK 14.3.A.0.757 fw; in order to root my device, I understand that I would first need to downgrade it to 14.1.G.1.534, install XZDR dual recovery and then get a pre-rooted KK fw - is that correct?
Thanks in advance for the help!
