Firmware for the Lenovo Flex 2 on mainboard LF14M, Wistron board number 13281-1, in a 3.27 MB RAR. Five-digit codes with a dash suffix, such as 13281-1, are typical of Wistron-made Lenovo boards, with LF14M as the project name. Use the dump to recover a machine that stays dead or shows no picture after a bad BIOS update by writing the SPI flash with an external programmer. Save the existing chip contents first and confirm the image matches the flash size.
