Firmware archive for the Lenovo Flex 14 on Quanta board DAOST6MB6E0, the variant with an Intel Core i3 and NVIDIA GeForce GT720 graphics, 3.37 MB in 7z format. Quanta boards carry DA-prefixed numbers on the PCB, and this name writes the zero as a letter O. Because the name specifies the CPU and GPU, check that the board on the bench has the same configuration. Write the image to the SPI chip with a programmer only after reading and saving the original contents.
