I recently installed a system with 3 T2-C+, one XP-3 and two RP-1. One of the T2-C+ was DOA, would not connect to the laptop. After a week, another one started displaying a black screen with a message that the file was not found and to download the file again. It would happen when the battery drops to low. Rebooting would fix it until it happens again. Latest firmware. Today the third one did the same thing. Is there some kind of an issues with recent T2-C+ shipments? I tried calling RTI but it is the same story again "must be a bad file, we are not at fault".
