There is probably a backup of TA.img on mobile.. It'll be in the sdcard. That's the home folder.

ok guys here is my problem
am trying to unlock bootloader for my xperia m.so safety purpose(re locking bootloader in future) i will take ta partition backup. according to my knowledge ta partition will change on different FW.
so am going to download 15.1.c.2.8 FW ,and flash that and take ta partition backup,so in future if i want to re lock bootloader i will flash first FW which i have downloaded and ill restore the TA partition.
is that fine? or do i need to take additional steps ,,,,, ????

In the quote of my previous post there is a highlighted part.
Just take the backup before you unlock the bootloader.
Backup TA partition before unlocking bootloader otherwise they will be lost forever

Look here if u want to unlock your bootloader - http://forum.xda-developers.com/showthread.php?t=2650510
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.

To get something u have to loose something.. There is no other way available.. You can take backup and restore.. If u dont want to backup restore then u have to stick with unrooted phone

Thanks already restored now my ta. One thing that surprised me though is that restoring supposedly relocks the bootloader which it did but the root maintained i thought relocking bl will also remove root and you have to unroot again with methods for locked BL
