@MaEtUgR do you understand this?

Is a warning that always shows on Cygwin because pyserial cannot set certain baudrates that are used for checking FTDI corner cases and so it assumes you're flashing through USB. Nothing to worry about there.

The real problem you're facing is that you try to flash, it sees the connected pixhawk and sends it a reboot to bootloader command: Attempting reboot on /dev/ttyS2 with baudrate=57600...

But then apparently the bootloader does not get recognized afterwards.

@oasinic Could you check if there are other COM port devices showing up in your device manager?
Because the bootloader will get a different COM port when it's connecting to your machine and if there's any other device the upload script could grab and get stuck on it would explain the problem. In that case you might want to test if it solves the problem temporarily disabling the other COM port devices to see if it helps.
