The GKD Mini Plus runs its Linux OS from the microSD/TF card, so updating means writing a newer stock image on a PC; there is no over-the-air patching. The stock build is commonly an IUX/ROCKNIX-style or plumOS image. Always update onto a backup or spare card.

FAQ

Is there OTA over Wi-Fi?
No. Even though the Mini Plus has Wi-Fi, firmware is updated by re-imaging the microSD/TF card on a PC.
Will updating erase my games?
Re-imaging overwrites the card. Back up ROMs and BIOS first, then copy them back to the ROMS partition.
