Hello, can somebody help me ?
I tried to upgrade my watch to the latest firmawre but that did not goes right.
The first try it goes up to 23%, I retry, it halts at 10%.
After a few try I reach 70% and then it stay at 0% after erasing. And finally the black screen.
I tried the UP, ENTER, POWER but nothing
After a night charging, still nothing.
The virtual com did not appear under Windows, and the screen of the watch is black.
Did I must press the 3 buttons simultanously or one after the other?
This must be done when the USB cable is connected or not ?
How long must I press the buttons ?
