New M5 PaperS3 Screen completely black, flashing FactoryTest shows successful in M5 Burner. LED blinks when power button is cycled and the device is found by M5 Burner. Pressing or long-holding the power button cycles the LED green, then flashing orange, but nothing changes the display from completely black. Have tried flashing other firmware as well, none permit the screen to refresh. Note that the screen is a solid black, not grey. No lines at all appear, all the pixels are activated at their darkest.
