hr + bug

Hi,

since a week my HR+ watch is causing problems. It started with a battery discharge in 1 day when I did not use it for an activity.
Then impossible to detect it in bluetooth. And now I can not even scroll anymore.
I did the update with the computer but I wanted to do a factory restore. And you have to access the parameters for that. I can not access it anymore (no scroll)

thank you for any help.
