I only have a 9600, and what I'm doing is simply unpack one layer of the installer after another with the tools available under Linux. The installer can be unpacked using 7z, resulting in a FirmwareUpdater.exe, a few DLLs and maestro_firmware.zip, which can of course be unzipped. The jffs filesystem images from there can be unpacked using jefferson ([Link: github.com]), or mounted directly in Linux using loopback devices.
