Steps

  1. 1Like other GKD Linux handhelds, the GKD Pro boots its OS from a microSD/TF card, so updating means writing a newer stock image on a PC.
  2. 2Download the latest GKD Pro stock OS image from the official source and extract it to a single .img.
  3. 3Write the .img to the microSD/TF card with balenaEtcher (Rufus also works).
  4. 4Optional: expand the FAT32 ROMS partition to fill the card, then copy ROMs and BIOS back.
  5. 5Insert the card, power on with POWER, and confirm the new build.

The GKD Pro is a recent GKD Linux handheld that runs its OS from the microSD/TF card, so GKD ships updates as full card images rather than over-the-air patches. Always update onto a backup or spare card so you can return to a working setup.

FAQ

Is there OTA?
No. Updates are applied 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 afterward.
