So I have an Elecrow 3.5 TFT, that would display with the PiAware 4.0 Waveshare 3…5" LCD touchscreen only the touchscreen portion didn’t function, so I got it in my head that I just needed to run the Elecrow TFT script and that would be it.
No joy and now no display either, figure I need to restore to the Waveshare overlays and dbt file.
@DaveBMD Haven’t tested with other LCD displays. But you could try adding the elecrow35a-overlay.dtb file to /boot/overlays/ and setting dtoverlay=elecrow35a-overlay in /boot/config.txt
