Thanks.
Let me tell you what I exactly did,
1. I downloaded the new boot file.
2. downloading the Oct.23rd bin file.
then, the receiver is on, and all I got is Bell channels but no any dish channel.
You mentioned in your previous reply, After downloading the boot file I should do factory default, I tried this but I got warning says all data will be deleted, Just for double check, do I have to do that after downloading the boot file, then I download the bin file and finally do channel scanning to retrieve all bell and dish channels.
Thanks
