Lumix Diaries How to Update Firmware on Panasonic Lumix Cameras & Lenses

Posted Mar. 31st, 2016 by Daniel J. Cox

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 web site seems to have a much simpler way and instructions for updating firmware. So here is the current information.

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, 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, please insert your formatted SD Card from your camera.
C. Open the zipped firmware file that you downloaded to the desktop.
D. 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, can use “Finder” if the drive does not mount to your desktop.
E. “Drag” to Copy and Paste” the .bin 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. This will
copy the file to the card.
F. If you choose to leave the SD Card in your camera, 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 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 smaller card, 16GB or smaller 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’s power back on.
B. Set to “Playback” Mode.
C. Choose the “Setup” menu.
D. Select Version Disp.

Update Firmware on Panasonic Lumix Cameras & Lenses

This Blog post was inspired by a recent email I received that I’m sharing below. Had this been the only email I’ve ever received on the pain Lumix users feel when firmware updates are released, I wouldn’t even be writing this post. But the email below is pretty typical of many folks I’ve heard from.

Hello, Dan

This past week I traded my Canon for a GH4, and I’m slowly becoming familiar with the m43 format. The body I received has Firmware 1.1; I know Panasonic has and continues to update this, but I am completely lost as to how to do this, and where to find that information in a clear and concise example (I need illustrations!). Their Web site wasn’t much help. Can you point me in the proper direction?

I should tell you, your work and explanations of the Panasonic cameras helped nudge me away from full frame (after 45 years); it was time for something new (video) while continuing to enjoy stills. I can already see the GH4 will meet my expectations, as it has yours. Thanks for sharing that part of your life.

Best, Bill

I want to remind all readers that Panasonic should be commended for offering updates to features they could easily save for future models but are offering as free updates. That’s a huge, huge bonus. But the pain in getting those new features installed needs to be cut to a minimum, or ideally eliminated completely.

Like Bill, who wrote the email I shared above, I also have spent many frustrating hours trying to understand how the Lumix update system works. The current update process is not easy, and I’ve explained this to the Panasonic folks more than once. 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.

The following are step by step instructions on how the update process works with screenshots of what you will see during the process. So let’s get started. First do the following.




Secondly, you need to get to the Main Support Page to start all camera and lens firmware updates. I’m going to use the newest firmware update for the GH4 as the example for this exercise. If you scroll down from the top you will see a heading tab What’s New. Screenshot below showing the page.


Screen Shot 2016-03-30 at 7.17.35 PM

Click on this link. This takes you to the next page which is completely confusing since it has virtually every other camera and lens but the GH4. To get to the GH4, you have to first scroll all the way down to the bottom of this web page. There you will see the title License Agreement. Below that is the option to select either Accepted or Not Accepted. Choose Accepted. You now are taken to a page that actually does list and has the firmware updates for the GH4. Screenshot below.

Screen Shot 2016-03-30 at 2.55.07 PM

Next, click on the Download Link for the GH4 in the far right column which takes you to the next page. The top of that page shown in screenshot below.

Screen Shot 2016-03-30 at 2.59.49 PM

As I mention above, this is just a screenshot of the TOP of the page you need. This page is confusing since it shows not only the newest GH4 update but it also shows a list of all prior updates. Even though the update you are after is described at the top of this page, you actually have to scroll all the way down to the bottom of this same page to see the Download option you’re after. It’s listed as the GH4_V25.bin and 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. On the Mac, the Download is saved to your Downloads folder or wherever you have asked your Internet browser to save them. Mine is the Downloads folder. I believe you can do the same on Windows, but that’s something you will have to figure out yourself since I haven’t used Windows since switching to Mac in 2004.

Once you have downloaded this file you have to GO BACK to the page you chose the GH4 from. Screenshot below and link here.

Screen Shot 2016-03-30 at 2.55.07 PM

Scroll about half way down this same page to begin seeing directions for both Windows and Mac. These directions talk about downloading the file to the proper place and making sure it downloads correctly.

Screen Shot 2016-03-30 at 3.22.33 PM

The above screenshot shows the beginning of the instructions for the Windows update process. 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. You need to go to the web pages I’ve provided links to for all the details.

Here’s a screenshot of the start of the Mac update process. It tells you to Download but we’re already past this part.

Screen Shot 2016-03-30 at 3.26.02 PM

So the above explains how you get the file to your computer and in a place you know where to find it, preferably the Downloads folder. Next we have to get this file onto an SD card to load to your camera. Putting this on an SD card is actually a superior procedure to a direct download to the camera from the Internet, which is the way Olympus does it. 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.

To prepare the SD card for this file, I always Format the SD card in the camera prior to loading the new update to the card. So Format your card first. Next, make certain the .bin file on your computer, the one that showed up after unzipping the compressed/zip file, is the same size as it shows on the Downlaod page.Screen Shot 2016-03-30 at 4.10.41 PM

Lumix stresses comparing the size of the files since it’s important to make sure the file was properly downloaded. 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.

Screen Shot 2016-03-30 at 4.07.36 PM

Ok, now t’s time to get this file on to you SD card. To start with, place the SD card into your SD card reader attached to your computer. If yo didn’t do the first thing I mentioned at the very top of this post, now is a good time to do it. This was the first step however so you should have this done. If not, DO IT NOW!


Next, navigate to the folder you put the file in, most likely the downloads folder and copy that file on to the SD card. Keep in mind, the file we are talking about could be either a .bin or a .lin or a .ebn file. I’m not sure why there are three different file designators, my guess is it depends on if you’re on a Mac, Windows machine, or possibly a Linux machine. But for Mac it has always been .bin when the .zip file is opened. When you download a Windows file it always comes through as a .exe file. Not sure if that file extension remains when you open the file, I can’t check since Mac won’t open .exe files, but look for .exe if you are on Windows. Once again Panasonic makes this very confusing by listing these two other files I’ve never heard of. Maybe there’s a good reason, but for me it’s always been confusing. Once either the .bin or .exe file is opened, you can copy and paste it on the SD card or just drag the file over to the SD card. Your file should now be on the card and ready to upload to your camera.Make sure this file is not placed in any of the FOLDERS on the card. Just drag the file to the open area on the card and drop it there.

Once the above is finished you will be at the end of this same page and you will see info on the next step that I’ve captured in the screenshot below. This could be much less confusing with better graphics such as photos of the specific cameras in each particular group. Same for the lenses, and almost nobody has any idea what the “Interface Unit” is. The box you want if updating a camera is “Procedure for camera body update (for camera body update with G series cameras).

Screen Shot 2016-03-30 at 3.33.36 PM


Click on that baby blue box which takes you to the next web page with very good, detailed instructions on how to actually load the file to your camera. Screenshot below. Notice the Charge the battery fully instruction. Make sure yo do this or you are dead in the water. You need a fully charged battery before anything else.

Screen Shot 2016-03-30 at 3.46.20 PM Once again, make sure you actually go to this page. The screenshot above is only part of the directions. Follow the instructions which are the least confusing of any in this entire process. Take a deep breath and read them slowly, read them carefully. Take one step at a time and all will work as it should. Unless of course you’re like a buddy of mine’s wife who he calls the Human Computer Virus. If so, then all bets are off. Just a joke to lighten the conversation 🙂

This post took a long time to write and only because this whole process is so confusing. Please add your voice about your upgrade experience to the comments below. I would love to get a large collection of people adding their opinion either god or bad. Who knows, maybe I’m stupid, and this is all as simple as flipping a switch, but for me it’s always been close to a nightmare. Maybe we can get Panasonic to make upgrades as easy to do as using their fabulous cameras.

    Dear Dan, thank you for your reply. Sorry to learn that you don’t follow Lumix issues anymore.
    I am in London, UK, it is less flexible here. I bought my camera from a reputable shop on line. I contacted the shop, they said they don’t do firmware upgrades. They offered to give me money back, but I want to keep my G9. Panasonic said to try Chrome, I did, but it did not work. A small repair shop, that does not deal with Panasonic, kindly upgraded my G9 to 2.7 using their Windows computer. But I also have GX9 and several Panasonic lenses, they all need upgrade. Panasonic support said that it was Apple’s fault. But Apple Genius expert said that Panasonic did not upgrade their software for the new Apple chip M1. He said, Panasonic software works with Windows and Intel, but not with M1. It is so frustrating.

      Inessa, I can imagine the frustration. Have you tried checking with the Limix Photographers group on Facebook? If it were me, I would join the group and start asking questions about others having issues with the M1 processor that you’re seeing. Here’s a link to that group.

      The other thing I would do is contact a local Windows repair shop. The smaller the shop, the better. I’m sure they could download and install the firmware update on your Lumix cameras for a fee.

  2. InessaOn Aug. 23rd, 2023 (1 month ago)

    Dear Dan, I hope you can still read comments to your article written so long ago. I would be so grateful if you could help. I tried to install most recent firmware (2.7) on my Panasonic G9 camera (I just bought it, with a 2.5 version). I use MacBook Pro M1 2020, with most recent Ventura. I downloaded the .bin file w/ the update in Safari, saved it on the SD card, but the camera could not read the SD card. It said “No valid picture to play”. Panasonic Customer services said they’ve known the issue with Safari for some time, that Safari seems to break or modify the .bin file downloaded from the Panasonic website, and the camera cannot read this modified file. They said to try to download Google Chrome, but this did not work either. Eventually I went to a small camera place that had a Windows computer, they downloaded the Panasonic update and updated my camera in no time. They used my SD card, they said it had nothing to do with the card. The camera could read the card and started the update immediately. Now I can’t update my Lumix lens. The same story, the camera says “No valid picture to play”. When I put the same SD card back into my MacBook, no .bin file shows on it anymore. I am not sure if it stays on the card after I eject Lumix.
    I’ve allowed pop-ups for Panasonic’s website in my privacy settings, as per old instructions. Can there be anything else in my MacBook’s privacy settings that I need to change? Or is it a problem with Ventura? Or with the M1 chip? Is there anything I can do to make the updates work on my MacBook? So many thanks.

      Wow, what a pain Inessa. Unfortunately, I’m not sure how to help at this point. I moved on from Lumix many years ago. I sometimes had issues with downloading their Firmware updates, but I always eventually figured them out. I find it hard to belive that Safari is at fault. I suppose it’s possible but it doesn’t make sense. However, just in case have you tried the lens update with Chrome? If that doesn’t work I would try Firefox. Finally, if you can’t make it work, why not approach your camera store, the one that did your camera, and offer to pay them to do the lens update. I’m sure they would do that for you. I know my local camera store updates firmware on cameras and lens for no charge if you bought the equipment from them. I would think $50.00 to get them to step in for you would work. Good luck and hope you can get this resolved.

    Hello: Hoping this site is still live:
    I was looking for a way to actually re-install software, not update. My camera was periodically doing strange things that lead me to suspect corrupted software. Tried the update path, but since the version in the camera is the same as the update, the updated software was not loaded. And Panasonic just sends the usual scripted service message. I’m positive that this is possible, but Panasonic may not tell anyone to ‘protect’ its rights, etc. Software designers always have ‘back doors’ and other ways of access.
    Does anyone know how to force the camera to reload its software.

      Dainis, Wow you are talking about doing something way above my pay grade. I have no idea how you would do what you suggest. Maybe somebody in the community will have an idea and respond.

  4. SkipOn Jul. 22nd, 2022

    Thanks so much for this really great step-by-step.

    Using this and this>>>
    The task was not nearly so daunting. I was easily able to update 2 Lumix DMC-L1 from version 1.0 to 2.1. One is a used model with ~9500 shutter releases and the other is a brand new DMC-L1K with the sweet/fast Leica lens.

    I wasted an hour or two trying to find the “Version Dspl”, not knowing that was added with V2.0. LOL.

    Regards, Skip

    Hi Daniel,
    Thank you for the detailed article and clear instructions.
    Hoping you can help my situ.
    I’m having 2 issues: My Gh5 won’t connect to my computer with the usb cable (I just get a lighting bolt with arrows pointing up and down) AND the firmware .zip folder I downloaded from the Panasonic site won’t open on my computer. I get an error message telling me that it is unable to expand GH5_V27.bin as it is in an unsupported format.
    So many dead ends! I am just trying to use my GH5 as a webcam.
    Thank you so much for any help.

      Daniel J. CoxOn Jun. 11th, 2021

      Ingrid, if you are seeing the .bin file it sounds like you’ve already unpacked it from the Zip file. You need to copy this .bin file to and SD card. First step is to Format SD card in camera. Then copy the .bin file over to the SD card from the computer to SD card. Next you need fully charged battery in camera. Shut camera off before inserting SD card into camera. Once SD card is inserted you can turn camera on. Next push the Play button. The same one you use to review a photo. By doing this the camera should see the .bin file on the card and give you a message to start the updating process. Select YES and it should work. I just did this exact procedure with the newest G9 firmware update and it worked perfectly. Let me know how it goes.

    I have never used your advice or needed it, but I just wanted to say how much I appreciate the help and support you make available to photographers.

    Good Job!

  8. Elizabeth HayesOn Jan. 7th, 2020

    I just updated the firmware on my two GH4 cameras. I went to a shoot yesterday, and everything worked great. Now, my iMac is refusing to transfer the .mov files to my hard drive, saying some of the data cannot be read or written.

    Any advice?

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Jan. 13th, 2020

      Elizabeth, I’m confident the firmware update has nothing to do with hour computer not reading these files. I could be wrong but I’ve never seen it in twenty years of shooting digital. Sorry, I can’t be more help. One thing you might check is the Movie settings in the menu. It’s possible the firmware set your camera to a default setting of AVCHD. That might be the culprit.

  9. MaikeOn Nov. 13th, 2019

    I have 2 Lumix GX8 camera’s, one with dutch language available in the menu and one that doesn’t. Both have the same firmware version number though, the latest. I tried to update the one without the dutch language, but because it has the latest firmware, it won’t update. Is it possible to get the dutch language available in the menu of my other gx8 camera?

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Nov. 14th, 2019

      Unfortunately, Maike, it’s not possible to change languages in the camera. Below is the exact response I got from my contact at Panasonic.
      1). Languages can’t be added
      2). His explanation tells me that the models differ, one likely an EU version and the other unknown.
      3). Languages are not part of the firmware. Languages reside in a separate memory chip on the main PCB, which cannot be updated or modified by the customer

      Sorry for the disappointing news.

  10. MohamadOn Oct. 23rd, 2019

    Unfortunately, I live far away from the United States, in Cameroon precisely (Central Africa).
    What I am sure is that theses firmwares are the firmwares I downloaded ( I followed the procedures and updated separately the body, then the FS014042 (which failed) and finally the FS45150 (which succeeded).
    Lets say that I accidentally put FS45150 firmware in the DS card to updated the FS014042; does it mean that my lens is dead?
    Thanks again for your help

      Daniel J. CoxOn Nov. 2nd, 2019

      Mohamad, unfortunately, I can’t decipher all that’s taken place with updating your lens and or whether it’s fixable or not. Do you have a dealer in your area?

  11. MohamadOn Oct. 22nd, 2019

    Hi Daniel.
    I am sure that the lens I downloaded the update was the exact lens I have. However, I remember an incident I forgot to mention in my last message. In fact, when I launched the update, the FS45150 lens I put next to my gh2 had rolled and hit it and it is right after that incident that the message ”Please Check that the lens is attached correctly” has appeared.
    Do you think that the failure of the update may have been caused by this incident?
    Thanks for your last reply

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Oct. 23rd, 2019

      Are you in the United States? If so I can send info on how to have this checked out. Not sure what else I can tell you without having it in my hands myself and knowing exactly which firmware you downloaded.

  12. mohamadOn Oct. 12th, 2019

    Hi Daniel,
    I came across your website while searching solutions to a problem I have been experiencing since yesterday. I own a gh2 and tried yesterday to make some updates, body firmware V 1.1 to V 1.2, lens FS014042 V1.0 to FS014042 V1.1 and lens FS45150 V1.1 to FS45150 V1.2. I successfully updated the camera body but when I tried to update the FS0140142, the screen show ”Please Check that the lens is attached correctly” (I thing) before the end of the process. I tried to Check the lens, turn the camera on and off etc. but nothing happened. I decided to remove the FS0140142 lens to update FS45150 V1.1 lens to FS45150 V1.2 lens and did it successfully. Then, I put back again the FS014042 and tried again but the same message appears. When I decided to check the lens version, it shows V1.2 instead of V1.1, the latest lens version. From there, I started wondering if I made I mistake by putting the wrong firmware and updated the FS014042 firmware with FS45150 firmware. Is there any solution you could suggest? I is possible to revert to the my old lens version?

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Oct. 12th, 2019

      Have you made absolutely sure that the lens you downloaded the update for is the exact lens you have? There is sometimes more than one lens that looks very similar. Check to make sure the lens numbers are EXACT. This is the biggest issue I see when an update doesn’t work. Please check and make sure then get back to me.

  13. NateOn Sep. 27th, 2019

    Hey Daniel, I was following this guide and when I got the step to set the camera in display mode and start the update it got half way done, the camera turned off, and now will not turn back on and I am at a loss… I followed the instructions step by step and cannot imagine what went wrong, and also have no idea what to do next? Is sending it off for repairs the only recourse, or is the camera just dead??

    Any response or assistance would be greatly appreciated.

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Sep. 27th, 2019

      Nate, I’ve never had a camera just quit on me during a firmware update. Did you have a full battery? That’s the only thing I can think of although it shouldn’t let you start the update if the battery isn’t full. Have you tried a new battery? Let me know and if all fails I’ll put you in contact with support to get your camera back up and running.

  14. MelanieOn Sep. 12th, 2019

    Thank you so much for this. I am updating GH-4’s with V 2.4 firmware. I was very uncertain about whether I should install the firmware in order (v 2.5 ; 2.6 etc) but your answer to someone earlier stated not to go backwards – to only install the newest version. I mean some computer updates are inclusive others not so much & it can really mess up a computer if not right

    So thank you so SO much. I love the camera, but even when it was under warranty – I had one question (a yes or no question at that!) that was not answered in the book – Panasonic would not even speak to me much less answer questions until I once again emailed every copy of every receipt even though I had registered all three cameras & lenses… That was ok, I truly do understand needing money for answers. But it would be nice if they had some basics like that on the site. You are the best & I thank you so much!! mel

    I’ve run into problems with my Panasonic Lumix DMC-FZ1000 – every time I press the playback button, the camera displays the last picture and entirely freezes – even the power off button doesn’t work. It also freezes if I access the settings for playback.

    Anyway, I decided to try updating the firmware, but unfortunately when I press playback to update it, it freezes.

    Do you know of any way to install a firmware update that doesn’t involve pressing playback?

      Unfortunately, they don’t create more than one way to update Firmware. It sounds to me like you need to have this camera looked at. I’m happy to send you the name of a Lumix contact person if you want to go that route. Just let me know via this discussion.

    I have just bought a DMC-TZ40 – the software version is 1.2 and I want to upgrade it to Version 1.3. However, when I follow all instructions and put the SD card in the camera and press playback it simply says ‘no photos to show’. I have bought another card and downloaded the software again.

    Will my configurations settings revert back to factory settings when the firmware is updated

  22. Garry KieferOn Jan. 28th, 2018

    When you update firmware on the GH4 do the configurations settings that I made revert back to factory settings?

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Jan. 28th, 2018

      Yes, unfortunately they do Garry. In the newer cameras, both gH5 and G9, they now have an option to save all our Custom settings to an SD card that we can reimport. That doesn’t help the GH4 but it does show they are moving in the right direction.

    Tell a nasty story. When you update lens Panasonic 12-35mm firmware 1.1 to 1.3 everything is frozen. Now at the start of the GH4 camera lens is not working but the camera displays the firmware to the latest 1.3. How can I reflash again the firmware? The answer is not found (

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Nov. 25th, 2017

      Not sure what to tell you Nick. It sounds like the camera and lens need to be looked at by Panasonic. Are you in the States. If so let me know and I will send you info for who and where to send your gear to.

    • NickOn Nov. 25th, 2017

      I’m from Russia. If I could get the firmware with a higher version such as m 1.3.1 or 1.4 then I’ll be able to update the firmware.

  25. John McHOn Oct. 23rd, 2017

    Appreciate the instructions in the blog, Dan. Just updated my new-to-me 45-175mm lens to ver 1.3 for my G85. Worked like a charm! I was somewhat hesitant to begin the update because the extracted .lin file (458,816 bytes) never matched the size stated on the Panasonic site (177,778 bytes). But after downloading numerous times and getting the same sized extracted file, I was pretty confident that the entire file had been downloaded and extracted properly. Thanks again for the post

    Thanks so much for providing this information. I followed your guide and successfully updated my G8 camera body firmware without a hitch. BUT updating my Panasonic Leica DG Summilux 25mm f/1.4 has been a different story. The lens shipped with frimware version 1.0. I’ve been trying unsuccessfully to update to the latest version, 2.1.

    I’ve followed all of your steps (and also the harder to follow Panasonic directions for the update process, once the card with the firmware file is in the camera)—to no avail. I’ve tried using different SD cards. I’ve been sure to snap a few photos after reformatting the card. I’ve made sure to use a freshly charged battery. I’ve turned the camera off, popped the card out, pushed it back in, turned camera back on and pressed play—upwards of 10 times. And still playback does not start the upgrade process; it just displays the photos I’ve shot, as it normally would.

    Thanks in advance for any insight or further advice you can provide.

      Daniel J. CoxOn Oct. 2nd, 2017

      Ben, this is a mystery to me. I have no idea why so many people have such difficulty getting firmware updates to install. I’ve had the same problems you describe but eventually had it work, following the proper steps, which you seem to be doing. The only thing I can suggest is to send your camera in, with the same SD card you’ve tried the install procedure with, and let Panasonic give it a shot. Hopefully, they’ll run into the same issues as you and can then document what is going on. You’re not the first to complain of firmware upgrade problems. I’ve tried to explain this to my colleagues at Lumix but they say they haven’t seen these problems. I appreciate you writing in. I’m documenting all of this so we can try and figure it out. If you want to go the route of sending your camera in I can send you a direct contact. Let me know. Sorry for this painful process.

  27. Robert GonzalesOn Sep. 25th, 2017

    I scanned the comments to see a discussion of updating firmware for Panasonic lens used on a Olympus body and didn’t see any. I am using the Panasonic Leica DG Vario-Elmer 100-400 lens on my Olympus OM-D E-1 Mark II. I tried to follow your steps (including having a couple of photos on the sd card etc) for updating the firmware for the lens and it will not start. The Panasonic website is totally worthless. I tried to direct connect the camera with lens attached to my pc to try the update from the Panasonic support site, but no go. It will not even start. However, updating Olympus lens with this direct connect method is very easy. Any suggestions. Thanks.

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Sep. 26th, 2017

      Robert, sorry to hear of your problems with getting your firmware updated. I’ve also had some issue as you’ve described with getting the camera to see the firmware file on the card. I recently did two 100-400mm Leica zooms. Both I followed the directions I have on my Blog that you refer to. The first one took the firmware and updated the first try. The second lens I had to take the SD card out of the camera several times and on probably the third time when I pushed the Play button the camera finally found the file and imported it. Please try the procedures outlined on my Blog again, and keep trying the Play button, maybe as many as ten times to see if it finally connects. Believe me, this is not the way it should work and I’m trying to convince Panasonic it needs to be simplified. Hang in there, we’ll figure this out.

  28. DejanOn Aug. 8th, 2017

    Hi Daniel,

    I just would like to inform you and yours readers what happened with my updating. As I explained in my previous posts I couldn’t find the way to update my GH4 firmware. I’ve actually despair to do it and I was waiting for your help. In meanwhile I was using my camera with SD card with new firmware on it and I did few new videos and new 59 photos on the SD card and after one week of use, I’ve turned my camera on again (same as many time in last week) and all of the sudden camera shows me an “update menu window”, I was very surprised, of course I’ve confirmed updating process and GH4 did the firmware update without any issue. So, finally I have the newest 2.6 body firmware on my GH4 camera. I hope it can help someone with the same update problems.

    Thanks anyway!

    All the best,

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Aug. 10th, 2017

      Dejan, Sorry for the late reply. I have heard of people having trouble updating if there is not at least one photo on the card. Sounds strange and I have no idea why this sometimes is necessary but I mentioned in my Firmware Update blog that it can be helpful to download the Firmware update and then shoot a photo on the same card as the update is on. I have no idea why this works and quite frankly I feel this is strange, to say the least. I’m planning to talk with Panasonic to figure out why this is sometimes necessary. However, it may explain why the Update window popped up for you after a week of shooting. Glad you are up and running. Once again please accept my apologies for not being able to help you sooner.

  29. DejanOn Jul. 24th, 2017

    Hi Daniel,

    do you haven any idea why I can’t update my GH4? I always got result: “No valid picture for play”. I believe I did exactly what I supposed to do for installing update.

    I have body firmware 2.2, the newest is 2.6.
    I have fully charged original battery.
    I had successfully downloaded the file “GH4_V26.bin” on my Mac computer (37,1MB) and copy it on first directory of freshly formatted SD card.
    After I put the card in GH4 and turn it on, I press the button “play” and immediately get written “No valid picture for play”. I have tried it for several times and always got same results. It’s seems to not recognize the file.

    I also wanted to try first to update with older version of firmware 2.5, but I can’t find it anymore. On official Panasonic websites I can find only ver. 2.6.

    I would very appreciate if you can help me.

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Jul. 25th, 2017

      Dejan, I don’t recommend trying to install an older version of firmware so it’s actually good it’s no longer available. I checked with one of my colleagues at Panasonic and the following is what he suggests.

      Very simple – he is not following one of the first steps we mention.
      1). His camera is likely updated – have him check the version in the MENU screen.
      2). The instructions state to have 1-2 photos on the SD cards – he does not.
      3).After a successful update, the camera reboots and enters the PLAY mode. Since he has no photos on the cards, it’s telling him that there aren’t any photos to display.
      4).The message says nothing about not being able to update the camera, nor does it say it failed.
      5).The truth is, the photos are NOT required, but we got so many calls about this misunderstood message that I added it as a step many years ago.

    • DejanOn Jul. 29th, 2017

      Daniel thank you and your friend for reply,

      probably I was not clear enough, I will fulfill my experience with update.
      1. My camera is definitely not updated, that is exactly what I’m trying to do – upgrade it from Ver.2.2 to Ver.2.6.
      In my GH4 camera: Menu > Version Disp. > Body Firmware > Ver.2.2

      2. I did tried to do update also with one, two and more pictures on my SD card. But it didn’t work.
      After I formatted my SD card I did pic(s) with the camera and then I had continued with determined procedure: turned camera off, put SD card out of camera, put it inside SD card reader, via MacPro copy new firmware on first directory of SD card, put my SD card with new firmware “GH4_V26.bin” on it in the camera again and turned camera on and pushed play button. But only result was that camera showed me the pic(s) I did before, without any update process. So my update wasn’t successful! My camera still has Body Firmware Ver.2.2.

      3. Doesn’t matter how I tried to do the update It wasn’t successful. It looks like my camera can’t recognize “GH4_V26.bin” file with new firmware on the SD card.

      I believe I do exactly what I supposed to do for successful update according to determined procedure from Panasonic company. If it can help to solve this problem I can also do the pic of every step I do in the update process.
      By the way I have also the GH3 camera and two Panasonic lenses and few days ago I did successfully updated both lenses, I’m almost sure I did it via GH3, because it has already last firmware (Ver.1.2) and lenses instructions says first update camera and then lenses.

      I would be very happy if you or your friend from Panasonic can help me to solve the update problem. Thanks.

  30. MikeOn Jul. 6th, 2017

    Dan –

    I would have never thought I would need to reach out to anyone to update firmware (not to sound too arrogant about it), but here I am, pleading for some assistance. Following Panasonic’s directions has got me nowhere, as has following every tip and bit of advice on this page. I want to do a lens firmware upgrade, and have everything in order, yet the camera (with lens attached) doesn’t recognize the bin file on the card (properly formatted in camera, with the bin at root level). It goes straight to photo playback.

    I realize that Japan really calls the shots on instructions and manuals, so I wouldn’t expect Panasonic USA to be able to furnish any other directions to those printed online.

    Any further suggestions in this saga? Many thanks, Mike

    • MikeOn Jul. 6th, 2017

      My bad, after reading this footnote I finally realized it why it wouldn’t update:

      “The firmware for M.ZUIKO DIGITAL ED 14-42mm F3.5-5.6 L differs from the one for M.ZUIKO DIGITAL ED 14-42mm F3.5-5.6.
      The latest version for M.ZUIKO DIGITAL ED 14-42mm F3.5-5.6 L is version 1.0. Firmware update is not required.”

    Thanks so much for sharing this! I followed the directions on the Panasonic website multiple times and kept getting a “NO VALID PICTURE TO DISPLAY” message even though the firmware was two versions behind…Your additional guidance about taking a few pictures on the formatted SD card before transferring the .bin file saved me what was sure to be hours of frustration. My GX7 is now happily updated to the lasted firmware version. Thanks again!

  34. James SegwellOn Dec. 3rd, 2016

    Am hoping you are the person that can solve a wee problem for me. I have the GH3 with the last v1.2 firmware but I want to re-install the firmware as I have some minor problems such as one of the function buttons don’t work and as I bought the camera in France it goes back to French language once it’s been reset. Problem is as the camera is recognizing the same firmware number it refuses to re-install it again. I even tried a minor ‘hack’ by re-naming the firmware number inside the .bin file but no luck. Is there a way to trick the camera into re-installing the firmware. Much appreciated.

    • Portrait of Daniel J. Cox

      Daniel J. CoxOn Dec. 7th, 2016

      James, I hate to give you bad news but I have no idea how to solve your problem. The reason is I’m a firm believer in purchasing all my gear in the country I live in. Why is that important? It’s because all camera manufacturers are basically franchises and part of the money we spend on the cameras in our home country is used to support the Lumix service center in that country. Again, I apologize I can’t be more help.

    Hi Daniel, Daniel here, I have a Japanese GX7 Mark II, or GX85 for the rest of the world, and I’m also trying to update the firmware from Sep 28, 2016. I’ve tried both .bin files given, for the GX80 and GX85 but I get the same message “no valid picture to display.” Camera firmware displays as V 1.0 and the update is V 1.1.
    I’ve formatted the SD card in the camera then copied the files over. I’ve tried having the lens on or off, same issue (lens is H-X015).
    Any ideas will be most appreciated.

      Here are the steps you need to take.

      · Format an SD card
      · Take at least ONE photo. He indicated he got the message “No Valid Picture to Display” – that’s why – no image on card.
      · COPY and PASTE (NOT drag and drop) the bin file to the ROOT of the SD card. The ZIP or EXE file can’t be used. The bin file is extracted from the downloaded file.
      · Use a FULLY CHARGED battery
      · Insert the card, place camera in “P” mode and turn camera on.
      · If the firmware update does not start on its own, make sure camera is in PLAYBACK mode.
      · It is possible, though unlikely that he corrupted the file, so if all else fails, download a fresh copy.

    • AgustínOn Dec. 29th, 2016

      Thank you Daniel.
      I don’t think there is something wrong with the camera. Maybe it’s just the combination of this “different names” issue and the X015 lens, which makes impossible for the camera to found the .bin file.
      If it’s necessary, you can give my email to your contact in the US, It’s not a problem.

      thanks again

    • AgustinOn Dec. 29th, 2016

      I could find the japanese web, which refers to the camera as GX7 MK2, and when I download the .bin file from there the name ALSO changed.
      From the global site the file name is GX85_V11.bin or GX80_V11 and from the japanese is GX7MK2V11.bin
      It seems that my camera was expecting that name. Thanks for your time. Hope this helps others too.

      The firmware you want to download should work just fine with your camera. The GX85 and GX80 are identical. Not totally sure about your questions regarding PAL. IF your camera does not have PAL option now, the firmware will not give you that option,

    I did the firmware update just this morning and it went well. The only thing I want to add is that on a Mac (with El Capitan OS ) when you copy the downloaded firmware file to the SD card, the file goes into the DCIM folder on the SD card. The instructions here are not to put it in a folder but we were unable to move it from that folder. It didn’t seem to make any difference. So success!

    Hello, Dan,

    I finally updated the GH4 firmware this evening; following your instructions, it worked fine. No errors anywhere.

    Another big THANK YOU for providing the map…

    In this interim I’ve also traded two Canon lenses for the Olympus 40-150 2.8, and bought the 1.4x; I might be able to live with only this zoom from now on, it’s that enjoyable. The close-focusing is a welcome advantage; shooting stationary leaf “portraits,” as I like to do, is easy, and the results as “sharp” as anything I’ve put on my monitor. Yes, the files are smaller, but…Wow.

    Thank you Dan, as always, for walking us through the update maze. I had no problems updating the camera bodies but have hit a brick wall trying to update to ver. 1.3 of the 12-35mm and 35-100mm Lumix lenses. The download time, when I click on the download page, is a mili-second and the resulting file extracted from the zip is a ES101513.lin. After copying it to my card and putting it into the camera with a fully charged battery I get the “No valid picture to display” message. I’ve tried at least four times on two different computers with the same negative results. I even had a friend, in Florida, download the file on her computer and mail me the zip file and had the same results. What’s up Doc?

      Robert Kozlarek responds:

      There is no problem at all ..
      He did the update (verify by checking the menu), but he failed to have at least one photo on the SD card. After rebooting, the camera goes into play, and he has no images on the card, SO … “No valid picture to display”.

      Check the camera enu with the lens attached and he will see the updated version.

    Dan, thanks so much for these instructions. Panasonic’s upgrade documentation is the worst I’ve ever seen. But thanks to this guide I got through it painlessly!

      Thank you so much for the kind words David. Happy to help. I’ve spoken to the one person who is in charge of this department at Panasonic US and so far he doesn’t feel it’s an issue so I appreciate hearing from those who have been helped by more clear information. Hopefully, comments like yours will help them realize they need to do better.

    Thanks Dan for this, which helped ease my GX8 firmware update. I found that extracting the .bin file to the top directory on a newly formatted SD card with a fully charged GX8 battery inserted did the trick.

    The instructions from Panasonic could indeed be clearer.

    In software development, “Easy is hard,” as Steve Jobs used to say. It takes a lot of time and effort and support structures to make computer interfaces simple for users.

    Camera companies are among THE WORST on the planet when it comes to simple updates such as this one. We should all demand better.

    The good news is that the camera that came out two years ago is a better camera now than it was then!

      Great input Bill. Thanks for adding your voice.

    In my attempt to update the lens and camera firmware, I was consistently told to add two images to the newly formatted card before proceeding to download the new firmware. Thanks Dan for your excellent instructions, albeit two weeks too late to save me from the difficulties I had getting thru the Pana “process” I use a mac and there is an important difference for moving the downloaded file to the card. If I remember correctly, Copy does not work but dragging file does…Dan you may want to check that out.

      Jim, I’ve added the .bin file to the SD card with both methods. First I “drug” the .bin too the card and started the update process, canceled it, then reformatted the card and then “copied” the .bin folder to the card. Both times the upload began to proceed. So if one way worked for you and one did not, there is something else going on. But who knows what, that’s what makes this process so frustrating. One minute it works and the next is doesn’t.

    Dan, thank you for answering my email in this way; I’ll block off a couple of hours and brew some strong coffee, then get to it!

    And thanks for caring about your fellow photographers,

    Dan, I did an update before reading your very thorough instructions, and it was a nightmare!
    Panasonic needs to fix this, just an awful experience. Thanks for taking the time to lay all this out so clearly!

    P.S. I get my 100-400 tomorrow, very anxious!

    Just spent almost an hour with Panasonic Tech support. Still not resolved. They referred my case to the next level. They will call me back. Charged me $9.95 for tech help for their problem.
    I will keep you posted.

  54. Kent JakuszOn Mar. 31st, 2016

    It was AH4_V25. I went to the site and downloaded the file again. This time it is GH4_V25 however, after placing the file on my SD card……..and hitting the play button I get “No Valid Picture To Play”. The instructions say “If newer version or same version of firmware has already been installed, the initial setup screen(Fig. 3) will not be displayed. And the camera body will display that “NO VALID PICTURE TO PLAY”. Please turn off your camera and use the camera as is.”
    My current version is 2.1. Might be that I need to upload the previous versions in oder? I have found tech support number and will call when they open. 800 211 7262
    Thanks for the help.

  55. Kent JakuszOn Mar. 30th, 2016

    Dan thank you for all of your efforts.

    But, I got the .bin file 37.1 MB and the .bin file 4.2 MB downloaded onto my MAC. The files were in a folder titled “AH4_V25. I am unable to open the files or copy them to my SD card????

    Any ideas?

      Kent, “AH4_V25” is this correct or is the A supposed to be a G in your comment above?

    • Kent JakuszOn Mar. 31st, 2016

      It was A should have been G. I got the A file from the portion of the website with the YAGH attachment. The tech also said that I should have been taking two pictures after formatting the card. Still don’t see that in the steps.
      Seems to me that they keep adding to the website and not updating or removing outdated postings. Nearly an impossible task.
      Patience. I gotta practice patience.

      All the Best

      Kent, I’ve never been told you need to add photos to the card for a firmware update. Just another example of this being very confusing. I appreciate your understanding for patience but your experience is driving the point home this procedure needs fixing.
