In order to install any ROMs other than stock, you have to root your phone and then need to flash custom recoveries like CWM (clockwork mode) or TWRP on your phone.

- Here we finished installing Flashtool now Open It.
- Click on the lightning bolt in the top left of Flashtool as highlighted below.
Select, ‘Flashmode’ and click OK
You should already be in the source folder where the FTF firmware files are located. If not, navigate to: “C:\Users\[Your PC Name]\.flashTool\firmwares” If you still not able to find the path check this too, “C:\Flashtool\firmwares\” now you should get it.
Select the firmware build version that you want to flash from the “Firmware” pane. Ensure the device variant is the same as the model number of your Sony Xperia device.
‘A clean install is the way to go‘
So 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 somewhere else.
Leave all others unchanged
Click on “Flash“. Flashtool will then indicate that it is “preparing files for flashing”.
Sometimes, you may have to wait around 60 seconds for the pop-up below to appear. Once it does, make sure that the device is powered off and then hold the ‘volume down’ button and connect the usb cable. Once the pop-up disappears and flashing has started, you can let go of the ‘volume down’ button.
Flashtool will then start flashing your Xperia device.
Once you see “Flashing finished” as indicated below, your Sony Xperia has been successfully flashed.
