Keep in mind, the screenshot above is just a portion of the instructions since I can’t fit all of them in a screenshot sample.
DO NOT just follow these screenshots—they don’t have all of the info you need.
Ok, now t’s time to get this file on to you SD card.
If you want horror stories about Olympus camera firmware updates which are caused by a direct download from a web page directly to camera, take a look at this thread on DPReview.The SD card is the way to go even though this whole process is painful.Several months ago I wrote a very detailed post on how I’ve been updating firmware for my Lumix cameras and lenses. 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. Drag the file from the opened folder to the device that either says Panasonic or mass storage to complete the transfer. “SDXC cards, 32GB or larger, require special card readers. The current update process is not easy, and I’ve explained this to the Panasonic folks more than once.The new information below is based on support from Robert Kozlarek of Panasonic US. Make sure the camera’s battery is completely charged. Download the latest firmware update for your model by clicking on the “Download Ver. X ” link to a location on your computer (we recommend the “Desktop”). If your computer has a media reader, please insert your formatted SD Card from your camera. Open the zipped firmware file that you downloaded to the desktop. For “PC” users, locate your SD Card by clicking on, or opening the “My Computer” or “Computer” on your desktop or your “Start” menu. If you choose to leave the SD Card in your camera, connect the camera to the PC with the USB cable. Depending on your PC, and the age of its operating system, you may not be able to directly write to such large cards. I’m hoping by bringing this to our readers, and by getting more input we can hopefully convince them they desperately need to update the ease of use on their firmware website. Secondly, you need to get to the Main Support Page to start all camera and lens firmware updates.If the file sizes are different, you don’t have a complete download and this could be a problem.
Screenshot below of my computers finder showing the files are the same as the file above.But for Mac it has always been when the file is opened.When you download a Windows file it always comes through as a file.It’s listed as the GH4_V25and has a Download Button for both Mac and Windows.Click on either Mac or Windows, depending on the computer you’re using and the download will begin.The US Panasonic web site seems to have a much simpler way and instructions for updating firmware. If the battery is not completely charged the firmware update will not begin. For “Mac” users, can use “Finder” if the drive does not mount to your desktop. “Drag” to Copy and Paste” the file from the opened folder to the drive with the SD Card showing in your “My Computer” window for “PC” users and “Finder” or “Drive” in Macs. 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. The following are step by step instructions on how the update process works with screenshots of what you will see during the process. I’m going to use the newest firmware update for the GH4 as the example for this exercise. This takes you to the next page which is completely confusing since it has virtually every other camera and lens but the GH4.
