Also, after the update, you are suppose to turn the 990 on in a special manner.

DO NOT turn it on by using the power button on the front of the 990 or by the remote. I think you are suppose to turn it on by pressing the "enter" and "menu" button at the same time.

read the instructions, print them, and read them again. And read them as you are doing the process. Take your time, and read carefully.
