Firmware version 1.15 for the Acer Aspire 7745G, configuration 464G50Mnks, distributed as a 631 KB ZIP. The configuration suffix ties it to one factory variant of the 17-inch model, so compare it with the label on the unit. A technician can use this to recover a board after a corrupted update, through the Acer flasher or an SPI programmer such as a CH341A. Unpack it, note whether it is a raw chip image, read and store the existing data, and verify that the file size suits the chip.
