One thing that bothers me about my Android phone is the opaque, closed-source baseband firmware ("radio" as it's often called here). Since the baseband is interposed between the OS and most hardware functions, its firmware presents a major unknown in the total security of the device.
It's unlikely that the source code for any of this baseband firmware is going to be released, and the open source OsmocomBB baseband is a long way off from supporting Android or the dominant Qualcomm chips. But I would settle for decompiling an existing baseband firmware image, so that I can start to understand some things about it's behavior, and perhaps compile modified versions.
Does anyone know where to begin with this? Many thanks.
