ZIP with Realtek RTS5452E Type-C controller firmware for an EM_AB819 board, v2.0, marked for the Pro Fortis M. At 163 KB the archive may hold more than a single image, so inspect its contents before flashing. The RTS5452E handles USB-C power delivery, and reflashing its SPI chip with a programmer is a common fix when charging through Type-C stops. Check that the board label matches v2.0, back up the existing flash, and confirm the image size suits the chip.
