или по точно това :

With the FC disconnected.

short the boot pins check " no reboot sequence" "full chip erase" "manual bauld rate". Checking the no boot sequence will bring up "flash on connect" check this.

Select required firmware "load firmware on line" and when ready connect FC usb and the firmware should start to flash the FC when finished disconnect and remove the boot pin short.

This is what I had to do to recover my FC after trying to update the firmware to the last 1.11.0 , firmware loaded but fail on verify. Hope you have a back up of your configuration as this will erase it .
