Technical Write-Up: Unlocking and Converting Siemens S7 MMC Images

C. WinHex / X-Ways Forensics

Function: Used for the raw extraction of data.
Workflow: Engineers use WinHex to read the physical sectors of the MMC. They can manually search for block headers (ASCII strings or Hex patterns specific to S7 blocks) to extract individual blocks manually if the file system is corrupted.

Issue 4: Snapdragon variant – Step-by-step doesn’t work

Reality: Snapdragon S7 requires RP-SWAP (Replacement Partition Swap) or using a Certified Bootloader exploit (CVE-2019-8954). You cannot directly unlock the MMC image on Snapdragon without an authorized Samsung service box. Consider using Chimera Tool or requesting a device-specific unlock service.

4. Tools of the Trade

While Siemens strictly prohibits unauthorized access, third-party tools have existed for years to aid in recovery. Note: Usage of these tools must comply with legal and IP regulations. unlock and converter mmc image s7

Key terms

MMC image: a bit‑for‑bit copy of an MMC/SD card used by the PLC.
Unlocking: removing vendor protections or encryption that prevent accessing file system or files.
Conversion: changing image container/format (e.g., raw .img, .bin, .dd, or mounting as loopback; converting to ext2/3/4 or FAT) to make contents usable on a host.
Firmware/Project files: STEP 7 projects, blocks, HMI files, user data.

1.1 What is an MMC Image?

An MMC image is a sector-by-sector forensic clone of the internal storage chip. Unlike a simple backup (e.g., userdata.img from ADB), a full MMC image includes: Technical Write-Up: Unlocking and Converting Siemens S7 MMC

Bootloaders (sbl1, aboot, rpm, tz)
Boot partitions (boot.img, recovery.img)
System partition (system.img)
Userdata partition (including lockscreen credentials)
EFS partition (IMEI and radio calibration data)
Persistent partitions (persist, misc)

Phase 6: Flashing the Converted Image

Boot S7 into Download Mode (Volume Down + Home + Power).
Open Odin v3.13.1.
Load your converted unlocked_converted.tar.md5 into the AP slot.
Do NOT check “Re-Partition” if you kept the partition table same.
Flash. The device should reboot without any lock.

Phase 2: Analyzing the Raw MMC Image

Open your mmcblk0.raw in WinHex. Navigate to sector 0: Function: Used for the raw extraction of data
