* Update the Arduino bootloader already on the board. This can resolve issues with Nano ESP32 being misidentified as other ESP32 boards.
* Restore the ability to upload regular Arduino sketches to a Nano ESP32 that has been flashed with the MicroPython firmware.

## Option 1: Using bootloader mode {#bootloader-mode}

The quickest way to reset your Arduino Nano ESP32 is by activating the bootloader mode and uploading any sketch.

Follow these steps:

1. Press the RST button two times, waiting 0.3 to 1 second between each press.

> [!IMPORTANT]
> The timing between presses is different compared to bootloader mode on most other Arduino boards. If bootloader mode won’t activate, try adjusting your timing.

2. Check the on-board LED near the RST button:
* **If the LED pulses slowly in green[^colors]:** The board is in bootloader mode. Go to the next step.
* **If the LED is off:** Repeat step 1 or try [Option 2: Use the Esptool programmer option in Arduino IDE](#esp32-download-mode).
3. Select Arduino Nano ESP32 in Arduino IDE or the Cloud Editor.
4. Upload any sketch to restore the standard Arduino bootloader.

## Option 2: Use the Esptool programmer option in Arduino IDE {#esp32-download-mode}

> [!TIP]
> Before you begin, it is recommended to have the latest version of the **Arduino ESP32 Boards** or **esp32** boards package installed using the Board Manager.

If you see this error, it means that the sketch is still being uploading with the regular upload process.
