16.60 firmware bricked my Fenix 6S Pro

Few days ago in the morning my watch stopped working. Just green triangle without any continuation.

Tried soft reset - it only turned on and off it, without help.

Tried hard reset - there are no signals on which particular buttons should be released.

All manipulations were performed during watch connected to PC, tried again in several hours (to be sure that battery is charged) - result is the same. Watch memory card is not visible at PC, just "Garmin USB GPS".

Then I opened current forum and observed numerous similar issues which were caused by deadly firmware update during that night.

I've installed Garmin Express. It connects to the watch, but when I'm logging into to update or maybe renew somehow that 16.60 firmware, but I do receive message "There was a problem connecting to the Garmin servers."

Tried WebUpdater as well, it detects the watch but it fails with message "The update file is corrupted."

I assume I do not have a warranty since I've bought not in official store in my country. I'm very disappointed taking into account that I was happy Garmin user (it was my first device) and was using it everyday for my sport activities.

Please help to resolve this firmware update issue.
