I have a "LiLyGo T5-4.7 S3 display v2.3" and after uploading an example from ArduinoIDE my display stopped responding.

Any demo I load, according to the serial monitor it works and prints debug, but the display still shows the original image it came with. Yet right out of the box it was working - the voltage values were updating.

I try to flash firmware "T5-4.7-plus_no_touch_firmware.bin" and again, no change. The display is dead - it shows the original screen of the first app it came with.

Any idea what to do?
