Firmware for the HP 15-r028tx, the Intel Core i3 version with a discrete GPU, built on Compal platform ZSO50 with motherboard LA-A992P; no revision is given. The TX suffix in HP codes usually marks models with dedicated graphics, consistent with the name. Use this image only on a board fitted with the graphics chip, since integrated-only variants may differ. Program it into the SPI flash with a programmer after backing up the original contents, and confirm the board number on the PCB and the image size before writing.
