Toshiba firmware image from a board identified as CID C50, with the name also mentioning EC.bin, suggesting an embedded controller dump; the file is a 2.00 MB BIN. EC firmware controls power-on, charging, keyboard and fan behaviour, so a corrupted EC chip can cause no-power faults. Read and back up the existing chip with an SPI programmer before writing, and make sure the chip capacity matches this 2 MB image. Verify the board model matches the C50 identification before flashing.

How to open a .bin file
A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
