Lumix G85 and GH4 Firmware Updates Instructions

Panasonic recently released Lumix G85 and GH4 firmware updates two firmware updates. The GH4 update address a problem I experienced on a regular basis where the the camera would shut down when using the battery grip with 1/3 battery remaining. The G85 update fixes an issue with the in-camera Image Stabilization not working exactly as some would want when panning quickly in video mode.

Several months ago I wrote a very detailed post on how I’ve been updating firmware for my Lumix cameras and lenses. It’s been quite popular. I was going to take it down and replace it with this new updated information but I’ve decided to just add this to the top of the original post so comments can be retained. The new information below is based on support from Robert Kozlarek of Panasonic US. The US Panasonic website seems to have simplified instructions for updating your firmware. So here is the current information.

Let’s Use GH4 as the Example

1. Go to www.panasonic.com. Click on “Support” at the top of the page.
2. In “Get Help” enter GH4, and select the GH4 when it connects you to the product page.
3. On that page, scroll down until you see “Firmware and Drivers” on theleft side of page.  It looks like the image below.


4. You will be taken to the latest version which also provides a link to a page with “Download and Install” instructions. Make sure you check the box “Agree to Terms”.

The download will start and it is put in whatever folder you have choosen on the PC. On the Mac it automatically goes in the Downlaod folder unless you’ve changed the default location.

1) Preparation before attempting the update

A. Make sure the camera’s battery is completely charged. If the battery is not completely charged
the firmware update will not begin. Format the SD memory card in the camera, and then take a
couple of pictures.
B. Turn off the camera.

2) Copying the firmware to your memory card

A. Download the latest firmware update for your model by clicking on the “Download Ver. X.X ” link to a location on your computer (we recommend the desktop).
B. If your computer has a media reader, insert your formatted SD Card from your camera.
C. For PC users, locate your SD Card by clicking on, or opening the “My Computer” or
“Computer” on your desktop or your Start menu. For Mac users, you can use “Finder” if the card does not mount to your desktop.
D. Open the zipped firmware file that you downloaded to the desktop.
E. Drag to copy and paste the .bin file from the opened firmware folder to the SD Card showing in the “My Computer” window for PC users and “Finder” or “Drive” for Mac users. This will copy the file to the card.
F. If you chose to leave the SD Card in your camera rather than inserting it into the computer (step B), connect the camera to the PC with the USB cable. Turn the camera on and set it to “Playback” mode. Then select “PC” on the LCD screen. Drag the .bin file from the opened firmware folder to the device that either says Panasonic or mass storage to complete the transfer.
G. SDXC cards 32GB or larger require special card readers. Depending on your PC and the age of its operating system, you may not be able to directly write to such large cards. If your PC asks
you to format the card, DO NOT—this is one indication that your system is not compatible with
the newer, larger memory cards. In this case a 16GB or smaller card should be used.

3) Updating the camera’s firmware

A. Turn the camera off, insert the SD Card if you copied the firmware to the card while inserted into the computer.
B. Turn the camera power on and press the “Playback” button. The Camera’s LCD screen should
now be showing a screen asking if you desire to update the firmware. Highlight “Yes” and
press the “Menu/Set” button.
C. When the camera has completed the firmware update it will turn itself off and then back on.
D. This completes the update process.

4) Confirming the update

A. Turn the camera power back on.
B. Set to “Playback” mode.
C. Choose the “Setup” menu.
D. Select Version Disp.

      Glad that helps Julie. All credit goes to Robert Kozlarek from Panasonic who directed me to the US Panasonic update web site which has much easier instructions than the one I originally linked to.

    Thanks and done. There’s also a recent update to the 14-140 lens.
