How to get the Sony Boot.Img file from Sony Boot.Sin

This guide will explain how to extract the Sony boot.sin file to get the boot.img file. To fully unlock your device’s capabilities, you’ll need access to the system partition and admin rights, which you can achieve by rooting your device using Magisk.

There are two ways you can root your Sony device:

1. Using TWRP Recovery to flash the Magisk app.
2. Without using TWRP Recovery. This method requires you to get the stock boot.img file, patch it with Magisk, and then flash it with Fastboot commands. While this second method takes a bit more time, many people prefer it because not all Sony devices support TWRP Recovery. It also simplifies some of the complicated steps in using a custom recovery.

Unlike some other phone brands that provide firmware files in ZIP format (like OnePlus with payload.bin or Realme and Oppo with OZIP), Sony uses SIN format for its firmware files, including the boot, system, vendor, and other partitions.

If you’re unsure how to extract files in SIN format, this guide will walk you through the steps to get the boot.img from the boot.sin file.

Rename boot.img File:

• • Locate the extracted boot.img file: It should be located in the “output” folder you created earlier.

  • Right-click on the file: Choose the “Rename” option.

  • Append “.img” to the filename: For example, if the file was originally named “boot.sin”, change it to “boot.img”.
