    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.

      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!

    2. gilles saint martinOn Feb. 10th, 2017 (3 months ago)

      thanks for solving my update problems
      I had, when in p mode, to click on the play button, as if I wanted to view my photos, and only then, on my gx8, did the firmware update menu appear !
      But t did work!

    3. James SegwellOn Dec. 3rd, 2016 (5 months ago)

      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.

        Daniel J. CoxOn Dec. 7th, 2016 (5 months ago)

        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.

    4. Alan PearceOn Nov. 14th, 2016 (6 months ago)

      I am trying to update my 14-140 lens without success. I am using a MAC. Every time I download the file it is smaller than shown. File size should be 174262 actually 458816 but it does say its the ES101912.lin file. Can you help?

      • Portrait of Daniel J. Cox

        Daniel J. CoxOn Nov. 15th, 2016 (5 months ago)

        Alan, have you tried loading the file that did download. I think you’re overthinking this. All I know is it worked fine for e and it was the same size download you say is a problem. Have you tried updating the .lin file that did download yet? Let me know how it goes.

    5. Daniel LazarOn Nov. 9th, 2016 (6 months ago)

      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.

      Thank you,

        Daniel, let me check with my contacts at Panasonic. Will update this in a day or two.

        Daniel J. CoxOn Nov. 15th, 2016 (5 months ago)


        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.

        Hi, nice to meet you.
        I found this blog because I´m having the same problem. I bought a GX7 MK2 in Tokyo with a X015 Lens and I can´t do the update.
        I tried everything exactly as you said. Also tried modifying the file name to GX7MK2_11 and it didn´t work.
        Did you find a solution?

        Thanks a lot for your time!

      • agustinOn Dec. 28th, 2016 (4 months ago)

        No. I´m in Argentina. I bought it 4 months ago in Japan.

      • Portrait of Daniel J. Cox

        Daniel J. CoxOn Dec. 29th, 2016 (4 months ago)

        Well I’m not sure what the next step is. If in the US I could have suggested a contact for you. Let me check with Panasonic here in the US to see if they have someone you can contact in Argentina.

      • AgustínOn Dec. 29th, 2016 (4 months ago)

        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 (4 months ago)

        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.

        Daniel J. CoxOn Dec. 30th, 2016 (4 months ago)

        Agustin, That for letting me know you got it figured out. That’s great news.

      • DanielOn Jan. 12th, 2017 (4 months ago)

        Hi Daniel, thanks for your help. As Agustin mentioned it must come from the Japanese website, which is here: http://av.jpn.support.panasonic.com/support/dsc/download/fts/index2.html
        The file is named GX7M2V11.bin.
        I uploaded this to my SD card and the camera did the update when it was set to playback mode.

      Thank you for your very helpful instructions! I face the same troubleshooting. After following the steps as described above, I managed to update the Camera Firmware (Lumix GX80 V.1 to V1.1) but not the lens ( Lumix 12-35mm V1.1 to 1.3). I keep on following every step, but no indication comes up when I press the play button.

    7. Michael ShapiroOn Sep. 29th, 2016 (7 months ago)

      Hi Dan! Not sure if you’re still actively checking this. About to update the firmware in my GX-8, which still has version 1.0 running. Do I need to update in chronological order, or does the latest update include all of the previous updates? Not sure if this works like an OS update, where everything is included in the latest iteration…

      • Portrait of Daniel J. Cox

        Daniel J. CoxOn Oct. 2nd, 2016 (7 months ago)

        Michael, To be honest, I’m not sure. I would be very surprised if it was necessary to do all updates to get the latest update. I’ll check in to this and post the answer here. Should be by tomorrow at the latest. Good question.

      • Portrait of Daniel J. Cox

        Daniel J. CoxOn Oct. 3rd, 2016 (7 months ago)

        Michael, I received word from my Panasonic contacts that NO it’s not necessary to add prior updates to get to the latest update. In other words, you are safe to use the most current update to get whatever you missed in the past. The latest update contains all updates you will need.

    8. Val StrawOn Sep. 2nd, 2016 (8 months ago)

      Just spent an hour and a half updating firmware on my Panasonic GX8 – wish I’d read this first and so does my husband who finally figured it out. Why is it so complicated and badly described – come on Panasonic, give us some clear, simple instructions please!

        Daniel J. CoxOn Sep. 2nd, 2016 (8 months ago)

        Could not agree more Val. I’m hoping these comments help them understand the difficulty of their update process. Thanks for adding your voice.

    9. DanielOn Aug. 30th, 2016 (8 months ago)

      I’ve run into quite the problem while updating my GH4. While the firmware update was happening, via SD card, the camera turned off. I immediately tried turning it back on. The green light went on, but the camera is making a clicking noise and the LED screen keeps going in and out. I cannot access ANYTHING through the menu. I’ve looked all over the internet for some answers but cannon find any. Hopefully you can help me out and point me in the right direction of getting my GH4 working again.

      Thanks again Dan. I read about the new GX8 update and tried to complete it without training wheels. Didn’t work. So, back to your blog, found the post and voilà, a done deal. I think I should bookmark it this time for the next time I forget how to do it.

    11. Dave ThomasOn Jun. 30th, 2016 (10 months ago)

      Hi…I sincerely appreciate all of your efforts, but I’m still stuck. I have watched dozens of videos, read ever thread and can’t get a human at Panny…I am stuck at 1.0 for both body and lens! I have used the oldest, slowest card I have, I have taken 1, 2, 3 and even 4 pictures after formatting the card, I have charged the battery for days, then put it right on and tried this.. I have the .bin, the .ebn (no .exe ever showed up) and still nothing…I just so distraught! Help me please!

      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!

      • Portrait of Daniel J. Cox

        Daniel J. CoxOn Jun. 20th, 2016 (10 months ago)

        Yvonne, thanks for the updated info. It’s possible that things have changed slightly since I wrote the original post. Will take a look for a further update.

    13. Bill StormontOn Apr. 21st, 2016

      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.

    14. Trent AndersonOn Apr. 20th, 2016

      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?

      All the best,

        Trent, hold tight I’m going to forward your message on to a contact at Panasonic.

      • Trent AndersonOn Apr. 20th, 2016

        Hold the presses! I was taking a shower, a most enlightening time for me, and I wondered if not having the actual lens on the camera would make a difference. Almost dripping, I put the 12-35 on the camera and the corresponding firmware and…”We have ignition.” Problem solved.

        Daniel J. CoxOn Apr. 20th, 2016

        Glad to have helped Trent:) Good news is your shower was short so that helps you guys in California since you can use all the water you can get. And better yet your lens has the most current firmware update. Thanks for reaching out. I did send Panasonic a note and Robert Kozlarek sent the response below. Maybe this will help others that run in to a similar issue.

        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.

        Happy to help Barry. Glad your up and running with the new firmware.

      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!

    22. Kent JakuszOn Mar. 31st, 2016

      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.

    23. 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.

    24. 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.
