Sometimes you want to see someone update a camera's firmware before you try it yourself.

Sometimes you want to see someone update a camera’s firmware before you try it yourself since it can be nerve racking. So I created this video of me actually doing it for the first time.

But you should read all the directions first before attempting this, if you don’t you can turn your $1,700 camera in to a brick.

Make sure your battery is fully charged or the camera will not allow you to do any of this.

Format your SD card before you start and then take 2 pictures before you put the bin file on the card.

Don’t worry too much, I have done a lot of firmware updates and I have never turned a device into a brick!

  • Just to say that I’ve never find any audio buzz in my GH4 bought 20 days ago in Europe/Madrid. Anyway I’ve updated to 1.1 version. Works the with the same awesome performance as before. I don’t work for Panasonic too.

  • I had a problem updating on my macbook pro, eventually got it to work by copying the bin file onto my desktop then copying it onto sdhc card then deleting all the other files (i.e. move to trash) leaving just the bin file on the card (128gb transcend). Put it into gh4 switched on then pressed play button and hey presto it worked!
    Thought this might be useful info for someone.
    Thanks for all your videos Dave.

  • Hi, can I launch the update with a legacy lens on the camera? I read somewhere that a lens have to be attached to do the update. I only have got legacy lenses (and for the camera is like having no lens attached) so I’m asking if I can do the update without risking to turn my camera in to a brick.. Thanks for your help.

  • Hi Dave, Thanks for the great helpful videos. Regarding the GH4 return for mic input audio fix, did you have to pay for the shipping? I know you mentioned they fix it for free but I wasn’t clear on the shipping cost. Thanks again.
