Understanding & Using the Flashtool:

1. After you’ve downloaded and installed the Flashtool, you’ll get a folder named ”Flashtool” in your C: drive, or the drive which you selected while installation.

The devices folder contains the supported devices, firmwares is the folder where you will place the .ftf file to be flashed in your phone, while the drivers folders has the Flashtool-drivers for all Xperia devices, you may install drivers through Flashtool in case you face any difficulty at the time of flashing.
4. Access the Flashtool-drivers and install Fastboot & Flashmode drivers as well first.
   
5. After the drivers have been installed, you’re good to go with Flashtool now. The first thing you need to do is, you need to download your desired file, that you are going to flash. It may be a firmware, a kernel or a root file, but it should be in .ftf format. Download the file and place it in ‘‘Firmwares” folder that is is in Flashtool folder.

This is for flashmode, in case you want to connect your device in fastbootmode, you need to connect it while keeping the Volume Up key pressed and you should see the Blue LED now. For older Xperia devices, the back key will work for Flashmode while the menu key will work for fastboot mode.
    
    
11. After you’ve connected your device successfully, the Flashing will start, wait and sit back while the flashing gets completed. You should see the logs now, as soon as it is done the”flashing done” will appear at the bottom.
