MG7720 Failed firmware update and now just a black screen with a blinking power button.

I used my MG7720 and it said it had a firmware update ready.  So I did as it said, went into settings and told it to update its firmware.  When I looked again it said it had failed it's update and to press the on button to try again.  I did that and now all I have is black screen and a blinking power button.

I too have the same problem. I initiated a firmware update as prompted but it failed. The update failed and I clicked the retry option after which the screen went blank with backlight and the power light keeps blinking.

I had the same issue, I unplugged the printer, waited about 30 seconds and then plugged it back in, it then downloaded the update and successfully applied it.
