A new development, same firmware (the latest one).
I searched the internet to find whether it is possible to downgrade the current firmware to the previous firmware version. In theory, it is possible. In practice, my watch started the downgrade process and then reported an undefined error and reverted to the latest firmware again. I did this procedure 3 times, unsuccessfully.
Each time after the unsuccessful downgrade, I did the hard reset of the watch. Plenty of time was spent on these activities.
Finally, after the last attempt to downgrade the firmware and a hard reset of the watch, I connected / paired the watch with the Suunto app in my mobile phone, and went to sleep. Yesterday morning, the watch warned me if I had wanted to switch on sleep tracking. I switched it on. Last night I went to sleep hoping that sleep tracking would work.
And it did.
I see this problem as one similar to firmware upgrades in mobile phones. Sometimes the new firmware doesnât âsitâ well and had to be reinstalled. Iâve been doing this on my phones for years. Now I did the same on the Race S watch.
Iâll see whether the problem is finally resolved.
