A journey on how to fix broken proprietary hardware by gaining code execution on it

How I hacked Sasmung eMMC chips: from an indication that they have a firmware - up until code execution ability on the chip itself, relevant to a countless number of devices. It all started when Samsung Galaxy S3 devices started dying due to a bug in their eMMC firmware. I will cover how I figured out there's a firmware inside the chip, how I obtained it, and my journey to gaining code execution on the chip itself — up until the point in which I could grab a bricked Galaxy S3, and fix it by software-only means.
