-## Before you begin
+Learn how to burn (flash) the bootloader on GIGA R1 WiFi.
 
-* Add the **Arduino Mbed OS Giga Boards** to Arduino IDE using the [Boards Manager](https://support.arduino.cc/hc/en-us/articles/360016119519-Add-boards-to-Arduino-IDE).
-* [Download and install the STM32CubeProgrammer from STMicroelectronics](https://www.st.com/en/development-tools/stm32cubeprog.html#st-get-software).
- * You will be required to provide and validate an email address to get a download link.
- * On macOS, you may need to run the executable directly: Right-click the `.app` container and select **Show package contents**, then navigate into `Contents/MacOs`. Double-click the file `SetupSTM32CubeProgrammer-X_Y_Z_macos` executable.

+## Prepare your GIGA R1 WiFi for bootloader flashing
+
+To burn the bootloader on GIGA R1 WiFi, it needs to be connected in DFU mode:
+
+1. Connect your GIGA R1 WiFi to your computer using a USB cable.
+
+1. Find the two push buttons labeled **BOOT0** and **RST** on the board:
+
+1. Press and hold **BOOT0** button.
+

+
+1. Keep the **BOOT0** button pressed down, and press the **RST** button once.
+
+ ![The RST button on Giga R1 WiFi.](img/GIGA-R1-button-RST.png)
+
+1. Release both buttons. GIGA R1 WiFi will briefly disconnect and reconnect to your computer.

+
+## Flash the bootloader with dfu-util (recommended)
+
+If you've installed the **Arduino Mbed OS Giga Boards** package on your computer using the [Boards Manager in Arduino IDE](https://support.arduino.cc/hc/en-us/articles/360016119519-Add-boards-to-Arduino-IDE) or Arduino CLI, you can use the included **dfu-util** tool to flash the bootloader on your GIGA R1 WiFi board.
+
+### Windows
+
+1. [Prepare your GIGA R1 WiFI for bootloader flashing](#prepare).
+
+1. Open **Command Prompt** by right-clicking in the bottom-left corner of the screen and selecting Command Prompt, or by searching for "cmd" in the taskbar.
+
+1. Copy this command:
+
+ `"%LOCALAPPDATA%\Arduino15\packages\arduino\tools\dfu-util\0.11.0-arduino5\dfu-util" --device ,0x0483:0xdf11 -D "%LOCALAPPDATA%\Arduino15\packages\arduino\hardware\mbed_giga\4.0.6\bootloaders\GIGA\bootloader.bin" -a0 --dfuse-address=0x8000000`
+
+1. If neccessary, modify the package version number (4.0.6) to whichever is installed.
+
+1. Right-click inside the Command Prompt window to paste the command, then press <kbd>Enter</kbd> to begin flashing the bootloader.
+
+> **Note:** To use Powershell instead of Command Prompt, copy this command instead:
+>
+> `&"$Env:LOCALAPPDATA\Arduino15\packages\arduino\tools\dfu-util\0.11.0-arduino5\dfu-util" --device ,0x0483:0xdf11 -D "$Env:LOCALAPPDATA\Arduino15\packages\arduino\hardware\mbed_giga\4.0.6\bootloaders\GIGA\bootloader.bin" -a0 --dfuse-address=0x8000000`

+## Troubleshooting
+
+### `dfu-util: No DFU capable USB device available`
+
+If you see this error, make sure you've followed the steps in [Prepare your GIGA R1 WiFI for bootloader flashing](#prepare).
+
+### `Cannot open DFU device 0483:df11 found on devnum 2 (LIBUSB_ERROR_NOT_SUPPORTED)`
+
+If you see this error on Windows, you may be missing the correct driver.
+
+Follow these steps:
+
+1. Open Device Manager and locate the **DFU in FS Mode** device under **Other devices**.
+ * If you can't find it, try selecting **View > Show hidden devices**.
+ * If a different device appears, such as STM device in DFU Mode (under Universal Serial Bus controller), right-click and select **Uninstall device**.
 
-11. Disconnect the board from the USB-C cable and connect it again.
+ ![Device Manager.](img/device-manger-dfu-in-fs-mode.png)
+1. Right-click on the DFU in FS Mode device and select **Update driver… / Update driver software...** from the context menu.
+1. In the wizard, select **Browse my computer for driver software**.
+1. Select **Let me pick from a list of device drivers on my computer**.
+1. From the list of device classes, select **Universal Serial Bus devices**. If you don’t see it, untick **Show compatible hardware**.
+1. Select **WinUsb Device > WinUsb Device**.
+1. Click **Next**.
+1. Confirm that you want to install the driver.
 
-[^1]: If you've installed the **Arduino Mbed OS Giga Boards** package, you can also find it inside your [Arduino15 folder](https://support.arduino.cc/hc/en-us/articles/360018448279-Open-the-Arduino15-folder). The path is `Arduino15/packages/arduino/hardware/mbed_giga/3.9.12/bootloaders/GIGA/bootloader.elf`.
+After installing the driver, try flashing the bootloader with dfu-util again.
