I still have not tried a back-up on my 9000i or tested the Ali Editor yet,so I can't comment on whether the process will work.(I have read that some owners have been unable to copy the files BACK to the receiver.IDK )But to be on the safe side,make sure you have the receiver updated before you do all the blind scanning and Sat positions.That way you are ok at least until you need a FUTURE update.
Turn the internet on the receiver and do the internet update.It was foolproof here.
I did the latest update over the Ethernet connection, which I like much better than having to go through the serial cable route. I did find the option in the menu to save my channel data to the USB Flashdrive, I will do that shortly; I just hope it works.
