The physical MMC is placed into a compatible internal card reader. A tool like S7ImgRD.exe reads the exact sector map to output a binary file.

When the reading process completes, you will be prompted to save the data. Provide a filename and save the .s7img file to your computer.

Once a raw binary image of the MMC was extracted, the unlock tool scanned specific hexadecimal offsets where the system block encryption keys were stored. The physical MMC is placed into a compatible

: Because the PLC was locked, engineers couldn't "ask" the CPU for the password. Instead, they would remove the MMC and use a Siemens Field PG or a specialized USB prommer to read the card’s raw data. Hex Extraction : Using software like , they would create a bit-for-bit image of the card. Password Retrieval
