Duplicate upload of the HP 840 G3 touch-version archive for Inventec motherboard 6050A2892401-MB-A01, sized at 7.26 MB. Identical name and size suggest the same contents as the other copy, which comparing checksums confirms. Inspect what is inside before use, as the name does not say whether it is a firmware dump or a diagram. Make sure your PCB carries the same 6050A number and revision, and read the existing flash before writing any image.
