Fast and requires no technical knowledge of bitwise operations.
cat cid
Identifies the company that produced the chip (e.g., Samsung, Micron, SK Hynix). Product Name (PNM): A 6-character ASCII string representing the chip's model. Product Revision (PRV): Hardware and firmware revision versions. Serial Number (PSN): A unique 32-bit number for that specific chip. Manufacturing Date (MDT): Month and year of production. Comparison of Decoding Methods 1. Linux Command Line (Native Support)
Before you can use a decoder, you must extract the hex string from the eMMC chip. JEDEC STANDARD - NXP Community emmc cid decoder
You must already have the hex string extracted; these tools cannot "pull" data from hardware. 3. Forensic & Hardware Adapters (Professional Grade)
Think of the CID as the "Digital Birth Certificate" or a "VIN number" for the storage chip. Unlike the firmware or the user data stored on the chip, the CID is programmed by the manufacturer during the production process and is intended to be read-only. It provides a standardized way for the host device (the smartphone, tablet, or IoT device) to identify the specific hardware connected to it. sudo mmc cid read /dev/mmcblk0 # Output hex:
Since Android runs on Linux, the method is identical, but you need root access because /sys is restricted.
