The GKD Mini is a MIPS/Ingenic device that boots an OpenDingux-class Linux OS from a dedicated firmware card, with ROMs on a second card. Updating means re-imaging the firmware card on a PC; there is no over-the-air update. Always work on a backup copy of the firmware card.

FAQ

Which card do I flash?
Flash the firmware/OS card, not the ROM card. The Mini keeps the OS and ROMs on separate microSD/TF cards.
Is there OTA?
No. The Mini updates only by re-imaging the firmware card on a PC.
