Hi Chris, the IC for the TFT is ILI9488 and we corrected the description on the Tindie page a week ago. sorry for the confus

sudo modprobe fbtft_device debug=3 rotate=90 name=flexfb speed=64000000 gpios=reset:25,dc:24,led:22

Every PiScreen is tested before we package up. We test the display and touch.

Can you disable SPI. In config.txt, place a # in font of
dtparam=spi=on

Add back the piscreen2 overlay;
dtoverlay=piscreen2r

If it still doesn't work, please show me the output ofsudo vcdbg log msg
