Fenix 6X Sapphire stuck at blue triangle


few days ago, I was updating my Fenix 6X using Garmin Express on my PC. I was using original cable and i wasnt touching the watch. The update failed so I disconnected the watch and since then, it is stuck at blue triangle. I tried soft and hard reset (holding start, back and light) but the watch does not even beep. When I connect it to the PC, it does not show up in Garmin Express but i cas still see it at a mass storage. Is there any way to resolve this issue?
