Firmware update will not run, or the camera misbehaves after updating

What causes it

• The update file must sit in the card root, on a card formatted in the camera.
• A partly charged battery can stop the update starting.
• Some features are gated behind firmware — the GF-2 flash needs a firmware update before a GR III or GR IIIx will use it.

What to try, in order

Moderate risk — one of these steps can make things worse if rushed.

1. Format the card in the camera, then copy the firmware file to the top level of the card.
2. Charge the battery fully first; do not attempt an update on a low battery.
3. Check the current version in the camera menu before and after, to confirm it actually applied.
4. If the camera will not power on after an interrupted update, that is a service job, not a retry.
