Firmware archive described as unlocked for the HP x360 1040 G8 convertible, at 13.3 MB compressed. It is intended to restore access on units locked by a supervisor password. No motherboard number appears in the name, so match the board visually and by markings before flashing. Programming is done directly on the SPI chip with a hardware programmer. Back up the original dump, since serial number and other identity data may need to be restored afterwards, and work only on equipment with legitimate ownership.
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 @biosfilebins. Enginerys does not host this file.
