GRKU.

Recovery

GRKU changes the camera only until the camera turns off. It does not write the firmware.

The camera stops during startup

  1. Try to turn the camera off.
  2. If the camera does not respond, remove the battery.
  3. Remove the SD card.
  4. Insert a charged battery. Turn the camera on without the card.

Do not push or pull the lens barrel. Do not remove the power during an official firmware update.

The camera still does not start

  1. Without the card, hold the playback button to start the camera in playback mode.
  2. If the menu opens, reset the camera settings. The reset deletes your personal settings.
  3. Turn the camera on again without the card.

If the camera still does not start, stop using GRKU and contact camera service.
