1. Download “Flashtool full install” and “Flashtool updates”.

Flashtool is an application that can be used to flash xperia devices. It serve many purpose, but in this example, i will only show you how to flash original rom. The version that i used in this guide is “Full install Flashtool package” and “update version v0.8.6.0”.


2. Install Flashtool full install first, followed by Flashtool updates.


3. Download the ROM that you need. The filetype for the ROM image should be “.ftf”.

Take note that some xperia devices such as xperia mini pro, it’s not the back button that you need to hold. It’s the “volume down button”. Do not worry because if you hold down wrong button, the on screen instructions won’t disappear. So just unplug your xperia devices and plug it back in while holding the correct button.


10. The on screen instructions will disappear once you have done it correctly. Now wait for the progress bar to start progressing. Yes, you may release the button that you hold just now. Please wait until the progress end. It will look something like the image below.
