Payload.bin is a file that you can often find in newer versions of the OTA or firmware updates. These files contain the stock boot and system images. Moreover, with the help of this file, you can take it as a base to create a custom ROM or even helps in unbricking of the device. In this post, we will guide you on how to extract payload.in from OTA or firmware using a script. This is the only method to get the payload.bin file as you cannot simply extract the contents by unzipping it.
Google now, packs in all the necessary and important files under the payload.bin file. Previously, you could directly extract the contents of the files but, thanks to the introduction of the Payload.bin, this isn’t the case anymore. You need to perform some additional tasks and run a script in order to extract the contents of the payload.bin file. Thanks to developer Gregory Monitor for creating the Payload Dumper Tool, you can now easily extract the contents of the Payload.bin file.

The A/B (Seamless) System Updates by Google is the new update process that offers the updates to be installed seamlessly without rebooting the phone into the recovery mode. It also reduces post-OTA failures that could make the device unusable if not properly installed or have some issues with the OTA update file.
Now, advanced users or developers can easily extract the ‘Payload.bin’ file that includes the individual partition images to flash on their specific devices whatsoever.
Whereas using the Payload Dumper Tool will obviously help users to easily extract the Payload.bin file and its contents to get the specific stock boot image or boot partition files. This will help them to install Magisk and Root access on their devices or even flash the firmware file via the Fastboot Method quite easily.
