1. Download BODYDATA.DAT from Sony's page (button below). You can also download it with Sony's Creators' App.
2. Format a memory card in the camera (this erases it), then save BODYDATA.DAT in the root of the card. Don't rename it, and keep only one BODYDATA.DAT on the card.
3. Use a fully charged NP-FZ100 battery: the update needs at least 51%.
4. Put the card in the camera. On the camera: MENU › Setup › Setup Option › Version › Body, choose Software Update, then Execute.
5. It takes about 6 minutes. Don't remove the battery or the card. The camera restarts by itself when it is done.

If the camera is hot, the update may not start: wait for it to cool down.

Put the card in slot 1: only slot 1 reads the update.
