That's with a different screen driver though, and looking at the LCD controller datasheets they use a completely different command set. Flashing that one will probably cause a nonfunctioning display.
Find another firmware with a driver for FGD177FLW (FGD0801 controller), and use the driver from that one instead of the ST7732 driver in the one I linked.
