How did you remove the metal cover from the moterboard (last picture)

slowrun - 답글

Where can I find a replacement Motherboard ? None of my buttons are responding and I can’t even do a Factory reset.

All that works is switching off and back on.

I have exact same issue. I sent my watch to official repair service to Split (Croatia) and they said they aren’t able to fix it. I can see only main screen of the watch, buttons don’t respond at all. Would like to know how to fix the issue.
