GKD Mini — Custom firmware

Quick answer

Button combo

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

Steps

  1. 1Confirm the chip: the GKD Mini is MIPS/Ingenic, so RK3326 firmware (ArkOS, ROCKNIX, Batocera, Knulli) does NOT apply.
  2. 2The realistic route is an OpenDingux-class build or MinUI made for the Mini's hardware, if a compatible release exists.
  3. 3Download a build specifically for the GKD Mini and prepare a dedicated firmware microSD/TF card.
  4. 4Write/extract the image to the firmware card with balenaEtcher per the project's instructions.
  5. 5Keep ROMs on the separate ROM card, reinsert both, and power on.

Choose firmware by chip. The GKD Mini is not Rockchip, so ArkOS/ROCKNIX/Batocera/Knulli are NOT for it, and muOS (Allwinner-only) does not apply either. Options are limited to OpenDingux-class firmware and possibly MinUI where a Mini-specific build exists. If you cannot find a build named for the GKD Mini, stay on the stock OS.

FAQ

Can I run ArkOS or ROCKNIX?
No. The Mini is MIPS/Ingenic, not Rockchip RK3326, so those do not boot on it. Use an OpenDingux-class or MinUI build made for the Mini.
Is custom firmware even available?
Options are limited and hardware-specific. Only flash a release explicitly built for the GKD Mini; otherwise keep the stock OS.
