Garmin 955 - How to delete donwloaded but not yet installed update 21.20

Hello to everyone!

I have a garmin 955 and although I have disabled the auto update function, it was still able to download the firmware when I connected it to my PC via USB. Now the update is downloaded in my watch but not yet installed and ti says that "it will be auto installed when I will not be wearing the watch or when the watch will be inactive". 

As I do not wish to install it, is there a way to delete the update file somehow from my watch to prevent it from being installed? I'm pretty much happy with my current version 19.18...

Thank you all!

  • - Close Garmin Express. (Make sure it's fully closed - i.e. the tray icon shouldn't be present)

    - Plug your watch into your PC (if the watch prompts you to go into MTP mode, answer yes)

    - Your watch should show up as a pseudo-drive in File Explorer ("Forerunner 955"). Navigate to the \GARMIN\RemoteSW\ folder

    - Copy all the files in RemoteSW\ to your PC's system drive (if you want)

    - Delete all files in RemoteSW\

    Alternatively, you could try to be strategic and only delete any files with an extension of GCD that are a few megabytes in size (which have the date that you expect to see). It probably wouldn't hurt to delete everything, but copying all the files to your PC first would allow you to undo the deletion if you want/need to, for any reason.

    (For anyone who needs to do this on Mac, you need 3rd party software like OpenMTP to explore your device's files and folders)
