GuliKit KingKong 3 Pro — Firmware update

Quick answer

Button combo

Controller FW: APG+A(on power-on)·BT module: SET(gear)+A(on power-on)

Steps

  1. 1Power the controller OFF, then connect it to a PC with a USB-C cable.
  2. 2For controller/CPU firmware: hold the APG button (double-square icon) + A to power on; a "GuliKit" USB drive mounts. Copy the unzipped .bin to its root; it flashes and powers off.
  3. 3For the Bluetooth module: hold the SET button (gear icon) + A to power on to enter Bluetooth Module Upgrade Mode, run the GuliKit update app and click "Update Firmware".
  4. 4Alternatively open the GuliKit Setup Tool (setup.gulikit.com) in a Chromium browser, set the pad to PC mode, and follow the prompts (requires firmware V5.7+).
  5. 5Do not disconnect until "Upgrade success!" appears; recalibrate sticks afterward if needed.

LED states

  • slow blink—Upgrade mode active / flashing in progress
  • solid—Upgrade success; controller will power off
  • blink—Update interrupted — reconnect USB-C and retry

The KingKong 3 Pro has two separate firmwares with different entry combos. The controller/CPU firmware updates by powering on with APG + A held, which mounts a "GuliKit" USB-C drive you drag the .bin onto. The Bluetooth module updates by powering on with SET (gear) + A held to enter Bluetooth Module Upgrade Mode, then using GuliKit's update app. The browser-based GuliKit Setup Tool at setup.gulikit.com can also configure and update the pad over USB-C and needs firmware V5.7 or newer plus PC mode. Always finish before disconnecting.

FAQ

Which combo for which firmware?
APG + A on power-on = controller/CPU firmware (drag .bin to the GuliKit drive). SET (gear) + A on power-on = Bluetooth module (via the update app).
Do I need to install software?
The Setup Tool is browser-based (no install) over USB-C; the standalone BT update app is a separate download for module firmware.
