To update the firmware/see the update notification you may need to update the app first (either in the App Store or Google Play store. Once you’ve done this, the update will be available in your Unleashed profile in the app. There will be a red notification badge next to the Unleashed in the bottom left corner of the main menu. Keep tapping on the fields with this red icon until you get to the screen that lets you install the firmware update.
Make sure the Unleashed is plugged into the camera, the camera is turned on and the app is connected. Tap “Install Update” and let the magic happen. Updating will take about two minutes and once it’s done, a big checkmark will appear.
For all Canon users: Please keep your camera “awake” by half-pressing the shutter button of the camera every ten seconds. This is necessary so the Unleashed gets power.
