When the firmware is corrupted on your remote, it can sometimes be difficult (or impossible) to establish communication and successfully re-apply the firmware using the standard Harmony Software user interface. If, after multiple attempts, you are not able to complete a firmware download, you may want to try downloading and launching a 'local' firmware file. These 'kernel' files either contain a complete firmware image or permit more direct communication by bypassing the initial Connectivity Check. In order to use these you will need to have the original Harmony Software (not the newer MyHarmony) already installed. Simply download the appropriate file (based on your model). Once downloaded, double-click to launch the file, USB-connect your Harmony remote and, with luck, the firmware will be successfully downloaded and restored. Please note - there is always risk when updating/re-applying firmware and we recommend that you do this only if all other troubleshooting options have failed. Note also that, on some models, you will need to re-apply your Activity/Device profile as the firmware update will wipe out these settings. You must have access to your Harmony Account in order to restore your Activity/Device settings back on your remote! Please contact us if you have questions about applying the firmware!
Having trouble installing the Harmony Software? Try using the original web-based version of the Harmony Desktop Software. Again, this is not MyHarmony, which is the new software that is used for all of the hub-based models, and other, newer controllers.
