How do I update the firmware of my Grit X/Grit X Pro?
To keep your watch up to date and get the best performance, always make sure to update the firmware whenever a new version is available. The firmware updates are performed to improve the functionality of your watch through new features and improvements.
Updating the firmware with a mobile device or tablet
You can update the firmware with your mobile device or tablet if you're using Polar Flow mobile app to sync your training and activity data. The app will let you know if there's an update available and will guide you through it. We recommend that you plug in the watch to a power source before starting the update to ensure flawless update operation. The wireless firmware update may take up to 20 minutes, depending on your connection.
Updating the firmware with a computer
Whenever a new firmware version is available, FlowSync will notify you when you connect the watch to your computer. The firmware updates are downloaded via FlowSync.
To update the firmware:
- Plug your watch to your computer. Make sure the charging cable is firmly in place.
- FlowSync starts syncing your data.
- After syncing, you are asked to update the firmware.
- Choose Yes. New firmware is installed (this may take some time), and your watch restarts. Please wait until the firmware update has been finalized before you detach the watch from your computer.
You won't lose any data due to the firmware update. Before the update begins, the data from your watch is synced to the Flow web service.
