No need to go back to 4.1.2. You can fully root 4.3 with this. It's 100% working for me.
Make sure you use CVE-2014-3153.

But I need to backup my TA and I think it can only be done in rooted phone locked bootloader. So, is there any Way?

You can root jb 4.3 using towelroot. You can find more info about it somewhere here in the Xperia m forum.

Here's the guide to rooting without unlocking the bootloader in 4.3:

Ok thanks how do I reflash the att stock image if I wanted that
Sent from my R800at using XDA App
once you have the bootloader unlocked and clockwork recovery installed you can make a complete backup of your phone in the recovery mode.
Thats what i did before i flashed a new rom. The stock att rom is not available here so you need to make a backup as far as i know
And ok I dnot want to unlock so I was going to go the route of flashing the other region firmware. But if I dint have the stock att firmware to go back to I dint want to do that. Guess I will have to wait to see if someone can figure out root without unlock. Thanks for the help though I understand now.

I had att but flashed to r800a 2.3.2 using wontanserver.com (its free just got to register) then used gingerbreak and updated OTA to 2.3.3 with bootloader locked. R800a is like att but no att bloatware.
Sent from my rooted R800a 2.3.3 BL locked
Right but if you ever wanted to go back to r800at stock firmware is there a way?
Sent from my R800at using XDA App
I was wondering this myself, since I too have an AT&T play, running the 800a firmware on GB. I've been having some issues with it though. Is it possible to go back to AT&T stock?
No unless you unlock bootloader and find someone who made a back up of the att rom.
What problems are you having?

To root you don't always need to unlock the bootloader.
If on gb.42 or ics then you can root using the easy root options. If on .65 then you will need to downgrade to .42 then root then ota to latest version.
Unlocking with setools is good and safe and still able to use pcc or seus.

And no you don't have to flash the ftf right after unlocking bootloader, you can do it anytime... Unlocking bootloader and flashing ftf are two different things

Hello Kaml,
Im not sure if rooting "by unlcking bootloader" is the only option you are considering but you dont need to unlock bootloader to root 4.3.
I rooted my Xperia on 4.3 following this thread: http://forum.xda-developers.com/showthread.php?p=51730927
If you want to unlock bootloader anyway, please, make a backup of the TA partition first: http://forum.xda-developers.com/showthread.php?t=2292598

Rooting with locked bl is too complex i didnt get it clearly and didn't used these tools before :/
Can someone please explain it to me clearly what to do
Sent from my C1904 using XDA Premium 4 mobile app
Hi Kaml.
Yeah, it's a bit confusing when you first go to it. If you dont like the adrenaline/fear/expectation mix, better is to ask someone else to do it for you
You say that's too complicated to root with a locked bootloader. That’s not always true, it’s relative. The post I linked to you is very clear and it’s not complicated at all, but you will need to start from a 4.2.2 rooted ROM, maybe that’s the complicated part for you.
Anyway, I suggest you to confirm if you can unlock your bootloader. Did you checked it already? It may save you time by knowing it beforehand.
To check, go to the dialer and type: *#*#7378423#*#* then go for Service info > Configuration > Rooting Status. If Bootloader unlock allowed says Yes, then you are able to unlock it. This is from thread http://forum.xda-developers.com/showthread.php?t=2484622
Read that thread, especially when it says “before unlocking please take backup TA partition from here”. By backing up the TA partition you can restore it later if need and then you have some chance of not losing Sony warranty if you ever need it.
Im not aware of other methods for rooting 4.3 besides the link I posted on my first reply, take a look and you will find other methods (probably).
Anyway, if you are interested in backing up the TA partition, it’s only possible if you have a rooted phone already and that’s kinda of a chicken/egg problem so that’s another motive of seeking for rooting methods without touching the bootloader at first. One way to solve it is to half root your phone, enable USB debugging and Unknown Sources from development menu, then run the script to backup the TA partition.

I'm not sure about over the air updates. However you can update your phone through PC Companion if it is rooted but the bootloader is NOT unlocked, and you can also flash an ftf onto the phone using flashtool if your phone is rooted even if the bootloader is unlocked.
There is also several methods of rooting 4.3, one of the easiest being towelroot as it is a one click root app for use on your mobile and it has the remount reboot fix enabled so you don't have to worry about that.

In the dialer type *#*#7378423#*#* (*#*#SERVICE#*#*) and click on Service Info and the Configuration. Under rooting status you will see a string of text. If it says Bootloader unlock allowed (either yes or no, it doesn't matter) your device has a locked bootloader. If it says Bootloader unlock: Yes then you have an unlocked bootloader.

Not at all, there are many root methods available for 4.3 now. The most effective is towelroot, if you download the most recent version from the website (do this from your phone as it is an apk) you don't even have to run the remount/reboot fixer as it is embedded into the app.
I have rooted my phone XMD its now 4.2 how can I update it to 4.3??
