Firmware dump in BIN form for Lenovo JS470 and JS570 machines on LCFC board NM-E051 revision 1.0, carrying BIOS version HTCN32WW according to the name. The ZIP archive is 5.17 MB. LCFC is the Lenovo-owned ODM using the NM- numbering. A technician writes this kind of image to the SPI flash with a hardware programmer when the laptop is stuck, bricked after an update or shows no display. Always back up the original chip, and make sure the board revision and flash capacity correspond before writing.
