payload dumper

Script tested on Yandex Amber OTA's (full and incremental) under Linux(but may works on Windows too)

System requirement

  • Python3, pip
  • google protobuf for python
    pip install protobuf

Guide

  • Make you sure you have Python 3.6 installed.
  • Download payloaddumper.py and updatemetadata_pb2.py
  • Extract your OTA zip and place payload.bin in the same folder as these files.
  • Open PowerShell, Command Prompt, or Terminal depending on your OS.
  • Enter the following command: python -m pip install protobuf

Full OTA

  • When that’s finished, enter this command: python payload_dumper.py payload.bin
  • This will start to extract the images within the payload.bin file to the output folder you are in.

Incremental OTA

  • Copy original images (from full OTA or dumped from devices) to old folder (with part name + .img, ex: boot.img, system.img)
  • run python payload_dumper.py --diff payload.bin
  • file extracted to the output folder you are in.
