Addition to my previous answer:

  1. It doesn’t list the flashing of the power and the other leds being off
  2. It doesn’t state that it will reboot and that the user will have to wait until the full reboot is done which is 65 seconds on my AR750S-ext.

I waited and nothing happened, still dead, redo it again and again… I didn’t wait for the full 65 seconds because I didn’t know.

Thanks
