What you need first

Read this before you download. The flasher needs a couple of things present on your PC, and the board has to be put into download mode at the right moment or the upload will never find it.

Windows 10 or 11 The flasher is a Windows program. No admin rights are needed to install it.
The Realtek AmebaD tools The flasher needs the Realtek AmebaD uploader to talk to the board. The download on this page installs those for you automatically, so there is normally nothing else to fetch. If you already have them from the Arduino IDE board manager, yours are left untouched. If you would rather install them yourself, Realtek's AmebaD Arduino support is on GitHub, and the tools themselves are in the Arduino_package folder.
A USB data cable, not a charge-only cable This catches people out constantly. A cable that only charges will power the board but will not appear as a serial port. If no port shows up in the list, try a different cable before anything else.
Your board's boot and reset buttons You need to reach both, and you need to be able to hold boot while tapping reset. Put your fingers in place before you press flash, because the window is short.

Your board is an RTL8720DN. If you want the chip documentation or the board package details before you start, Realtek's AmebaD page has it. Anything you install from there is left alone by our installer.

How to flash

Run the exe The flasher opens straight away, and installs the Realtek AmebaD tools it needs. Nothing else to set up first.
Connect the board over USB Plug the B&W16 in. Windows should present it as a serial port.
Put the board in download mode Hold the boot / download button, tap reset, then let go of boot. The uploader only looks for the board for five seconds, so do this the moment you press flash. If it says the board was not in download mode, it timed out - just try again.
Pick the port and hit Flash Select the serial port from the list and start the upload. Do not unplug the board until it reports success.
Reset the board Power-cycle or press reset to boot the freshly flashed firmware.
