I just got a new HDVR2 from a surplus store and installed a 500g Maxtor HD with version 6.2a on it from instantcake. I'm trying to get the 6.4a version to download through the phone but I don't know if that will work. Can someone tell me if I can get it that way or do I need to get the newer version of Instantcake to do it, or is it possible that Directv can send it through the satelite line?

Thanks, beanhead90
