How to extract FTF and system.sin file of any Sony Xperia phones
In this tutorial, i'll show you how
to extract FTF firmware and system.sin file using 7-ZIP and Flashtool. This
method will work for any Sony Xperia phones that uses FTF. These programs can
be downloaded from the internet
7-Zip: http://www.7-zip.org/
Flashtool: http://www.flashtool.net/index.php
Note: Flashtool require Java JDK
Let's get started,
I have a FTF firmware file of Xperia
Z3 Compact. I would like to see what's inside the firmware so I'm going to open
the FTF with 7-Zip.
Right click -> 7-Zip -> Open archive
You will see the files inside FTF
file. These .sin are images to extract .sin to partitions, example: System.sin
copies to /system.
System.sin is the Android OS image,
so extract that file
Wait, you can't open .sin file with
7-Zip. You'll need to Extract data first
In Flashtool: Click Tools -> Sin Editor. Select the system.sin file and click Extract data. It
will some times to extract system.ext4
file
Open system.ext4 with 7-Zip
That's all.
You can extract everything,
customize the firmware/ROM and make it into a flashable.zip
I'll recommended to use PRFcreator
to create stock firmware with your custom ZIP.
