Quick answer

Button combo

(power off)(power off)write CFW image to microSD/TF

Steps

  1. 1Confirm the chip: the GKD Mini Plus is Rockchip RK3566, so use RK3566 firmware. ArkOS is RK3326-only and does NOT support it.
  2. 2Choose ROCKNIX, Batocera, or Knulli; download their RK3566 (or device-specific) image.
  3. 3On a separate microSD/TF, write the image with balenaEtcher.
  4. 4If using a generic RK3566 build, follow that project's notes for the Mini Plus (display/controls may need a device profile).
  5. 5Insert the card, power on, and finish setup (Wi-Fi, theme, ROMs).

Pick CFW by chip. The Mini Plus is RK3566, so ROCKNIX, Batocera, and Knulli are the relevant options, typically via the generic RK3566 image. ArkOS targets RK3326 and is NOT compatible; muOS is Allwinner-only and does not apply. Exact support can vary by build, so verify the Mini Plus is listed/working before flashing, and keep your stock card.
