Generic software image named update.img, 14.3 MB, with no brand, model or version in the name. Files with this name are often firmware update packages for TVs, Android-based boxes, car head units or similar devices. They are loaded from USB or with a vendor flashing tool rather than a chip programmer. Since the target device cannot be identified from the name, check its origin and any accompanying notes before use. Flashing the wrong package can brick the unit, so keep a backup of the current firmware if possible.
