payload dumper of online

中文

This is a modified version of payload dumper that supports the following features in addition to the original features:

1. Extract partitions directly from a zip archive containing payload.bin without unzipping it.
2. Extract partitions directly from a URL (such as an OTA update URL) containing payload.bin from the network without downloading the entire file.

With this script, you only need a small amount of time and storage space to extract the partitions you want from the OTA update package or address, especially the smaller partitions such as boot, init_boot, vbmeta, etc.

Future Outlook: Maybe it can support extracting some files in system partitions?

usage

pip install git+https://github.com/5ec1cff/payload-dumper
payload_dumper --partitions <partitions you need> <file path or url>
