Sure you can :)
9.2.A.1.210 is better because it's the last.

If you flash with Flashtool you can't root, because there's not a direct method yet.
The only way to keep root, is flashing a pre-rooted 9.2.A.1.210 via recovery.

FTF files for Flashtool are in General section, instead ZIP files for recovery are in Development section.
Good luck ;)

1) Install recovery

Download here: http://www.androidfilehost.com/?fid=23269279319202175
Take your phone, go to settings, developer options, turn on and select USB debugging.
Connect the phone to PC now.
Unpack CWM4XperiaT_v8i_JB.zip
Run install.bat/install.sh
Follow the instructions, remember that your device is V, keep an eye on the display of the phone and give root permission when asked.
After the end of the process, enter into recovery like this: turn off the phone and turn on.
Immediately, try one of this combination:
Press repeatedly (not holding) power button until the phone vibrates
OR
Tap repeatedly the screen

2) Once you're in recovery, make a BACKUP.

So if something will go wrong or simply if you want to go back to 4.1.2 because you don't like 4.3, you will be able to return to the present situation just resuming this backup.

3) Install .210

Remember that you will lose all your data and apps. Instead what is inside internal memory and SD card is SAFE (backup included)
Download and install Flashtool
Download THIS and move it into the directory C:/Flashtool/firmwares
Download .210 zip file HERE and copy it into the internal memory of your phone.
Turn off and go into recovery.
Make a wipe data/factory reset.
Then install zip from sd card, choose zip from sd card, select .210 zip file.
When it's done, select POWER OFF (be careful, DO NOT select reboot).
Open Flashtool, click on the lightning symbol ("flash device"), select "Flashmode" and click on "OK"
Now select LT25_9.2.A.1.210_1268-6904_FIX4.3 and click on "Flash"
Wait for a window to pop up
Now take your phone, push the volume-down button, keep pushing and connect to your PC
Once the flashing process has started, release the volume rocker as soon as possible
NEVER disconnect the USB cable until it's finished!!!
Turn on and enjoy! :good:

Remember to hit THANKS to steveboss HERE for creating .210 already rooted ;)

1) If you want to keep root you must download LT25i.210_nor_deodex_root_philz_v1.zip that I linked above, since it's already rooted.

2) When you flash zip via recovery you don't touch the old kernel. You flash only the new system. After that, you need to flash the new kernel, so you need Flashtool with LT25_9.2.A.1.210_1268-6904_FIX4.3

3) When you switch from an Android version to another, a full wipe is always recommended. A partial wiping could give strange behaviours.
Therefore it's better a fresh installation of the app and then (when possible) a resume of the backup offered by the app: for example I'm quite sure that Whatsapp has a backup option within its settings. Use THAT option if possible with any app. Right?

Wipe cache is already included into factory reset.
Wipe dalvik cache is not mandatory in this case... do it if you want ;)
Anyway all wipes will be repeated by Flashtool, so don't worry about that.

In Flashtool you have to change NOTHING, since yours is a brand new installation. Just flash. :)

LOL... I'm not so noob. :D
Yes my method is for locked bootloader.
Unlocked bootloaders have to flash another kind of kernel.
The kernel you're installing is the original one.
And no, you can't unlock an Xperia V through Flashtool. It's impossible at the moment.
The only way to unlock is getting a code through Sony site!!!
This rule is valid for all 2012 devices onwards.
You're too anxious :D

anyway thanks so much , you explain everything for me like a real master and i`m going to update my firmware now :eek:

i get error : device not found , on run install.bat , but the root message come on phone and my phone reset ! why this happend ? i need driver ?

Unlocking is mandatory for new Xperia that can't be rooted directly, because they are too new and they've been released with 4.3 or 4.4
We don't have this problem because we have 4.1.2 that is easy rootable, so we can install recovery and do everything we want ;)

I did this million times with locked bootloader.

During the process does your phone ask for root permission? Do you tap on yes?

Click to collapse

in first time yes , the root permission Comes and i tap on Grant

then the phone reset and the error device not found apear in install.bat cmd

i though maybe the driver not installed so i download and install Driver again , even i try http://adbdriver.com/upload/AdbDriverInstaller.exe and this tool show that my Driver is ok !!

    Well, according to Xperia Update Checker by Macmol, your device is Movistar Colombia and here is the problem, because it's still with 9.1.A.1.140 firmware.
