I just changed the battery on two Flash 2.0 systems. Now neither one of them has any feature codes anymore. I just get NONE REGISTERED when I do an XFTEST, and of course the systems won't come up. I had never seen this before, don't know what to do. I have searched TEK-TIPS, but I don't find any previous posts. Also, if I have a Flash vm lite and want to upgrade it to a regular 2.0 Flash, do I need keycode for that?
