Hi,
After synced my FR235 via cable, my heart rate monitor stopped working. I looked at the WHR firmware and it was 0.00. I tried to install via Garmin Express, it didn't work. Tried to install via WebUpdater, still, it didn't work although it said the installation was successful. I tried that again and again, still, it was 0.00. I also tried this website http://gawisp.com/perry to update the sensor hub manually, but still not working.
Thank you very very much for your support.
