Uppercase EC.BIN image of 32.0 MB with no laptop model, board number or firmware version stated, which makes it uninformative on its own. Real embedded controller firmware is usually far smaller, so this is more likely a complete SPI flash dump that contains BIOS and possibly EC regions together. Identify the platform by searching the image for strings, keep a backup of the original chip contents, and confirm the board number on the PCB before programming it with an SPI programmer.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
