I'm wondering if someone could clear something up for me. There's the me_cleaner project that the above guide relies on in order to generate the new BIOS image. However, I thought me_cleaner could be run directly without dumping, modifying, and reflashing an image using the Pi. What's the difference in efficacy between the above guide and just using me_cleaner directly?
