The best way to do this is to install Sony PC Companion and S1Boot USB drivers .Make sure you connect your Xperia to the PC before starting the process to download the necessary USB and ADB drivers.

The best way to do this is to power off your Sony Xperia and then connect to your PC whilst holding the volume down button.

2-Install Sony tool

B-Install Sonytool drivers from the following location: ‘C:\Flashtool\drivers’Tick the “Flashmode Drivers” and “Fastboot Drivers” and driver for your device to install.

*If you want to retain your apps, data and media (photos, videos, music, locks), then ensure that the “USERDATA” option within the “Wipe” pane is unticked. 

However, we recommend that when upgrading a major new Android version, a clean install is the way to go. In this case, tick all options under the “Wipe” pane. This will wipe all of your data though including your photos and videos, so please ensure you have these backed up elsewhere. note: If you want to reset screen lock, then ensure that “USERDATA” option within the “Wipe” pane is ticked.

-Flashtool will then indicate that it is “preparing files for flashing”.

*You may have to wait for the pop-up below to appear. 

-Once it does, you should now connect your Sony Xperia device. Make sure the device is powered off and then hold the ‘volume down’ button Connect USB cable. Once the pop-up disappears and flashing starts, you can let go of the ‘volume down’ button.

-Flashtool will then start the flashing process.

-Once you see “Flashing finished” as indicated below, your Sony Xperia has been successfully flashed.

-Remove USB cable, press power button untill you sense a vibration, just wait few minutes for phone to fully powers on.
