Part 6: Frequently Asked Questions (W-King D9 Firmware)

Q: Does the W-King D9 support OTA (Over-the-Air) updates? A: No. There is no companion app (like the W-King App, which exists only for newer models like the D10 and X10). You must use microSD.

Q: Will updating the firmware erase my EQ presets? A: The D9 has no user-savable EQ. It resets to the stock "Rock" curve. You will need to re-adjust your source device EQ (Spotify, phone settings).

Q: I bought my D9 in 2024. Do I need an update? A: Probably not. Units manufactured after mid-2023 ship with firmware 3.1 or 3.2. Check by holding Volume + and Play/Pause. Part 6: Frequently Asked Questions (W-King D9 Firmware)

Q: A website is selling a "Custom Firmware" for the D9 that boosts bass by 50%. Is it safe? A: Absolutely not. These are scams or malicious files. The D9’s DSP (Digital Signal Processor) has hardware limits. Forcing more bass will blow the passive radiators. Stick to official firmware.

Q: Can I downgrade to an older firmware version? A: Usually yes, by following the same process with an older .bin file. However, if the newer firmware updated the Bluetooth chip's bootloader, downgrading may fail. Keep your original file safe.
