Flash 5Ghost firmware on the PINGEQUA BW16 (RTL8720DN)
Install the 5Ghost dual-band (2.4 / 5 GHz) WiFi research firmware on your PINGEQUA BW16 (RTL8720DN) board directly from this page. You need Chrome or Edge on a desktop computer and a USB-C data cable.
Firmware is hosted and the flasher is ready; on-hardware flash validation is still in progress.
How do I flash the BW16?
Connect the board over USB, click Connect, then Flash. The flasher first tries to enter download mode automatically (DTR/RTS). If that fails, hold the BOOT button, tap RESET, release BOOT, and click Connect again.
Which browsers can flash the BW16?
| Browser | Supported |
|---|---|
| Chrome / Edge (desktop) | ✅ Yes |
| Chrome (Android) | ✅ Yes |
| Safari (macOS / iOS) | ❌ No |
| Firefox | ❌ No |
Browser flashing relies on the Web Serial API, available only in Chromium-based browsers.
Troubleshooting
| Symptom | Fix |
|---|---|
| Stuck at "entering bootloader" | Hold BOOT, tap RESET, release BOOT, then click Connect again. |
| No port in the picker | Use a USB-C data cable; install the CH340 serial driver if your OS needs it. |
| Flashing is slow | The BW16 flashes at 115200 baud, so a full image takes a few minutes. |
