      Hi

      I'm trying to get my Core S3 into programming mode to reflash the demo but can't. Pressing the reboot button down for a while makes it go green but then it goes back to normal mode. I've tried everything to get it into the programming mode without success. Is there anything else I can try?

      Steve

        Hi Bipman,

        Make sure you follow the steps below:

        1. Connect the device to your PC via USB
        2. Turn on the device (via the BOOT button on the top left) and wait for it to boot.
        3. Now press the RESET button on the bottom right until the green light comes on and then release the button.

        The screen should stay black now (backlight will be on though), this means you're in programming mode.

        Also very important: download the latest M5Burner tool from the M5Stack website: https://docs.m5stack.com/en/uiflow/m5burner/intro
        Else it won't work either.

          @marnix201 Thanks. Just tried it and all as described except it doesn't find any ports. There is no beep from the computer either to say I've attached a device. I've tried several different USB ports on the PC too without success.

            Do other devices work / get recognized by your PC with the exact same cable ?
            Try to use another USB Cable, some Cables only have power in them and no Data wires.

            Try different ones (USB C to USB C, USB C to USB A )
            Maybe try to connect it to another PC or Laptop ?

            Also: try to check your Device manager to see if anything changes while plugging / unplugging the device, maybe it's a driver problem (altho normally you won't need any drivers for the S3 Devices)
