Firmware extraction from eMMC

Method 1: eMMC tapping

  • Identify a pinout for an embedded Multi Media Card (eMMC) flash chip (embedded SD card)
  • Dump the contents of the chip without removing it from the PCB
  • Similar to in situ reading (dumping firmware from running device)

Method 2: eMMC unsoldering

  • Identify a pinout for an embedded Multi Media Card (eMMC) flash chip (embedded SD card)
  • Unsolder (remove) eMMC from the PCB
  • Plug-in eMMC to an adapter
  • Dump the contents of the chip after

NOTE: These two methods are also applicable to SPI Flash
