Firmware set for the Acer Swift 3 SF314-57G, built on the NB8511_PCB_MB_V4 mainboard, with both the system BIOS and the EC (embedded controller) firmware in a 5.46 MB RAR archive. Having the EC image alongside the BIOS helps when a board fails to power on, charge or respond to the power button after a corrupted flash. Write each image to its own chip or region with an SPI programmer, after backing up what is already there. Check that the board marking reads NB8511 V4 before relying on it.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
