After installing the correct drivers and checking the usb multiple times. Following the instructions for DFU mode i still get the error . I tried using “dfu-util -l” as suggest in another forum and it says cannot open DFUdevice. Any suggestions on how to proceed i need to update the firmware on the device.

I was unable to detect any devices in DFU mode... > Your device will blink yellow when in DFU mode. > If your device is not blinking yellow, please: 1) Press and hold both the RESET/RST and MODE/SETUP buttons simultaneously. 2) Release only the RESET/RST button while continuing to hold the MODE/SETUP button. 3) Release the MODE/SETUP button once the device begins to blink yellow.
