Chip-Off Firmware Extraction on a Linux Embedded Device

In this video, we demonstrate a chip-off firmware extraction on a Linux embedded device, using the proper amount of flux. We use the XGecu T56 universal programmer to read the firmware off the TSOP48 M29W640GT flash chip made by ST. After reading the firmware, we show how to reattach the flash chip to allow the device to be functional again.
