Georg Lukas, 2025-05-05 18:40 This is a follow-up to the Samsung NX mini (M7MU) firmware reverse-engineering series. This part is about the proprietary LZSS compression used for the code sections in the firmware of Samsung NX mini, NX3000/NX3300 and Galaxy K Zoom. The post is documenting the step-by-step discovery process, in order to show how an unknown compression algorithm can be analyzed. The discovery process was supported by Igor Skochinsky and Tedd Sterr, and by writing the ideas out on e...
