Guys Now the Upgrade time:
first of all :

• Charge your phone at least up to 70% so that flashing process won’t get interrupted.

• Temporarily disable any Anti-virus solution installed on your computer.

It is highly recommended to backup all your data from internal memory (includes contacts, messages (SMS/MMS), call logs, Internet APNs etc.). Your phone data will get lost after installation of this firmware (excluding External storage).   
Procedure:

• Install Flashtool that you’ve just downloaded in your computer. For the sake of convenience, install it in root directory of C: drive.

• Navigate to ‘C: –> Flashtool –> Firmwares’ and delete all the data from this folder (if present).

• Now move that .ftf  file in the above mentioned directory.

• Open Xperia Flashtool. Select Flash option (Black Bolt icon) from the top left corner of the tool (Refer to image given below).

• It will ask you to select either Flashmode or Fastboot mode. Select Flashmode & proceed further by hitting OK button.

• On next screen, Firmware selection window will appear. On left side, select ‘LT26i (version 6.2.B.0.200)’.(NOTE: select firmware what u want)

• In right side of the tool, tick following 4 options (Caution! Don’t tick any other option than 4 mentioned below).

• Press OK. Wait for Flashtool to prepare firmware installation.

• Now, it will ask you to connect your phone. Before you connect your phone to computer, enter into Flashmode on it. To do so, switch off the phone completely. By holding Volume down key, connect it to PC. If done correctly, you should see a ‘green/blue light’ on the power.

• After establishing proper connection with the computer, flashing process will start automatically. Firmware installation process may get stuck around 93%, which is normal. It stays there for 20-30 seconds and not more than that.

• Once you get “Flashing finished” message in Flashtool, remove your phone from PC & wait for it to reboot (It may take more time than usual for booting the device. This is for the first time only. So don’t get panic & be patient).

Congradulations guys !!!! your mobile was upgraded!!!!!
