Failed flashing t186ref.

Thank you in advance,

I found this solution :
You should follow these steps exactly and in this order. Use an USB hub if possible.

  1. Unplug the USB flashing cable from the USB hub and from the Jetson
  2. Power off the Jetson
  3. Run this command on the host

sudo -s
echo -1 > /sys/module/usbcore/parameters/autosuspend


* Replug the USB cable into the USB hub and the Jetson
* Power on the Jetson and put it into recovery mode
* Flash
but it didn't work also , what can i do ?

Suggest to have a host PC with native Ubuntu.
