Arduino Nano 33 IoT Not Showing COM Port and Bootloader Flashing

I recently purchased an original Arduino Nano 33 IoT, but when I try to connect it to my laptop, it doesn’t detect the COM port. I’ve tried pressing the reset button, but that didn’t resolve the issue. Could you please help me identify the problem and let me know how I can flash a new bootloader? Alternatively, could you advise if the Arduino might be faulty?

Hello Alam,
To troubleshoot the issue, you can consider the following steps,
1. First, disconnect the Arduino.
2. Check the
Show hidden devices
3. Reconnect the Arduino and
Scan for hardware changes
4. You can refer to;
https://forum.arduino.cc/t/arduino-nano ... ed/1223411 and
https://forum.arduino.cc/t/bootloader-com-issue/981135
5. Double-press the reset button on the Arduino quickly. This should put the board into bootloader mode, and a new COM port should appear in the Arduino IDE.
If these steps don’t resolve the issue, you might need to flash a new bootloader.
To burn the bootloader in the Arduino Nano 33 IoT, you can refer to;
