so I did watch the video and unplugged the printer when the load gets stuck around 80%. when I plug the printer back in it turns back on automatically (I didn't need to press the power on button) and the firmware loading process continues on my computer screen. this is where it then jumps from 80 to 99%, but then stops and gives me that error message. This is what I don't understand, am I supposed to continue on with the activation process or is there in fact an error with the firmware install process I need to fix?
