conrado,
have sure you are working with the correct blaster.
each blaster will have your own devices.. (I think square connect could be include a option to import the devices, macros and codes from another sqblaster to help a set up equal devices in different rooms).
Yep, got the SQ-1b6b, and the 17d9(the one that its not working)
the SQ-1b6b
has: Samsumg tv, logitech, cable tv, DVD, etc...
when you select Samsung Device for an example, there is an option: wich blaster!
this way you can import from one SQ Blaster to another!
But the SQ-17d9, doesnt learn the IR codes from the remotes when i set up a new TV (LG)
not eaven send a blaster signal, from the OLD Samsung tv,
but when i load the Samsung Tv back to the SQ-1b6b
works fine!
