Hello.

Thank you for your inquiry. We have a few questions about this situation:

  • When firmware was being flashed, was device LED blinking fast constantly?
  • Which firmware was used before upgrade?
  • How device didn't turned on again (didn't connect with computer, didn't turn on,...)?

Have a great day!

Hello,

thanks for your reply

  • Yes the device leds were bilinking but I'm not 100% sure it was fast or not I was watching the updater to show the done with the green background which it did.
  • I'm not sure but I think it was FM5500.01.03.13.Rev.0.e.
  • Device isn't turning on and leds are not bilinking but when I connect to the PC I can see the COM4 but can't connect to it through the latest version of the configurator.

Thank you for your answers.

To solve this problem please contact your sales manager or a company who you bought a FM device from because we can't solve it in forum.

Regards.
