Model 3700-CBSV build

[Patrat]

I have a model 3700 echostar with a build config of CBSV that I'm trying to set up with an AVR-x for a freind. I did the sector erase of SA5 and streamed it for 2 hrs. The software version remains at 853pcbsv-n. I have been trying to find a TSOP for this reciever but I can't find one with my build. Is it critical to use the same buid? Can the builds be modded to work? I am currently getting the preview channels but nothing else. I have a 3900 system that is working well with the avr, but I'm not having much luck with this one. I had the reciever turned off while I was streaming it and had the box checked to update without permission.

Ya know as I was writing the above post it just occured to me that I had selected 3900 model when I programmed the AVR. I changed it to 2700 and reprogrammed and its working fine. I also checked the sortware version it's supposed to be 853.p I was thinking p239. Sometimes I get tunnel vision and can't see the obvious, but hopefully I learned.
