I can't ever get them to take a software update when they are initially turned on. This results in activating and then trying to force the software update, which normally works. I've had about two that refused to be forced and then started while I was activating clients. This resulted in the C41's returning to the enter pin screen once the HR44 updated. The C41's always find the flash update while I am trying to program the remotes. I did an upgrade where the customer had one HR22 that was a swap, her only receiver. A service tech had been there a few months before and replaced the pole, dish, lnb and all the connectors. Simple. The HR44 wouldn't update. Once activated the default was show all channels. A channel up got me a 771 on the sd locals. She said that was fine, I disagreed. The signal strengths were all perfect, except for the zero's straight down the middle on the 101. Once the software finally updated after about four RBR's and 02468's everything was straight. Everything seems really stable once all the software updates are done. No service calls for gray screens. WooHoo!
