I have an Ionic with a damaged screen and the replacement worked until last week firmware update… it is dead since then… How could I replace the screen from the dead one to the broken screen but working ?
Remove the strap from the wrist heat the watch slowly to approx. 80 degrees Celsius gently(!) place a opening tool between the glass and the frame of the watch and lift the glass carefully and slowly disconnect the connectors replace the glass put everything together WARNING: Be very carefull, since the rubber seal between the glass and frame is easily damaged and you need it to seal the watch. I haven’t found any spare part for this yet and I did not managed to preserve it.
