How to start?
Reset the watch by plugging and unplugging the USB cable four or more times. See it yourself on short 30 sec video:
What to expect when battery is visible (normal watch mode)
At succesful reset, the screen will then go completely dark in a characteristic way and won't respond to tapping. This means the watch has been completely shut down. Please wait 10-15 seconds for complete power down.
Plug Swimmo into the USB port to wake it up again. You should see "Swimmo" logo.
What to expect when green light flashes (unfinished update)
The screen will still not react after reset. That's normal. The only effect of resetting the watch in unfinished update state is making sure that watch advertises properly via Bluetooth. This needs to be done in pair with instructions on this page.
At succesful reset, you should see Swimmo on the list. After that you can restore your watch firmware by reconnecting via Swimmo app.
