librephone Project

This is a project to research proprietary files in Android to work towards a long-term goal of free replacements. While there are many proprietary libraries and other files in Android, this project is focused on binary blobs. Initially the research is focused on identifying the best device for software development. And also documenting how the blobs get used by the kernel as a guide to what it would take to clean-room legally reverse engineer them.

If there is sufficient interest and funding, a detailed specification can be written and used to have somebody code a free implementation that works the same way.

Utility Programs

This project contains several utilities for analyzing proprietary files and binary blobs in Android. They are oriented towards any developers wishing to duplicate the research on their own. If you want to use these, chances are you might have to edit a few paths.

These utilities require you have download the Lineage install package for the devices you are interested in researching. There is also a top level script images_util.sh that can automate the processing of multiple devices.
