I have had no problems with my 910 XT for three years. However, I went for a run yesterday, after which I saved the workout and then took off the watch inside the door and like often happens, the watch started to sync with my computer upstairs. Unfortunately, mid-sync, it froze on me. I couldn't do anything with it in this state, including turning it off, and so I let the power drain then recharged it. Once charged, I restarted it and it began to transfer data. However, it is always unsuccessful in doing so and continuously reties to sync. I have deleted all files on the watch except for the last run so it is not because their are old files on the watch. I use Chrome typically but I also tried using Firefox to upload with no success.
Apparently, I have loaded on my watch the latest software update so that doesn't seem to be the issue. I have changed USB ports as well to check that but that is not the issue.
Any thoughts?
Thank you,
Kim.
