What is a SIN file?

A SIN file is a firmware file used to distribute updates to Sony Xperia smartphones and tablets. It contains data, such as a partition image or kernel image, used to update the Xperia device. SIN files are typically stored in .FTF files, which are flashed on to a device.

More Information

Most users will not encounter SIN files since they are distributed in FTF files. However, some users may extract them from FTF files in order to modify and create custom firmware files for Xperia devices. Users can unpack SIN files (version 3, 4, and 5) with the UnSin tool.

Common SIN Filenames

kernel.sin - Contains a compressed kernel image and is stored in an FTF file.
