I've had H20s in the past do exactly as you're describing. Fail on 110/119 for no reason, yet they still worked fine. I've also had them succeed on setup for all 3 sats, then not show certain package channels and have to fight with the unit during setup until it just decided to show the channels.
First thing I would try is to force a software update. Reset the unit and at the blue screen hit 0, 2, 4, 6, 8 on your remote. After the update retry setup.
Once you are getting success on those, try out channel 494. It should say Test 5, Sat C (110) Even TXp 18v. If you have that message, call activations back and try again.
It may not work the first time they send the the re-auth, it may not work the second or third. But just have them send it over and over and try resetting the box here and there. Eventually it WILL work. Sometimes threatening the H20 with a crowbar helps.
Good luck.
