Sounds like you did a master reset and bricked it. I did the 4 Step to no brick at my website and show 4767 channels currently. How many satellite tiles do you have? I have 67, after a MR you end up with 21 and loose all other digital channels (above 24) except X4.
I guess I win some and loose some. This 920 was out of the loop so long that the x4/w5 sat was missing, so even if I did the no brick, I don't think if I did the no brick , I would of been able to get the w5 channels.
I'm also not keeping it, have it for sale on a site. I have a 922 coming from clist. Hopefully w5 is in it.
