I had problems with cheap eBay cable. Mine would not stay connected. I think maybe I got a dud? Anyway there's that and battery has to have good voltage. I now use a genuine rosstech cable and hook a battery charger up to keep constant supply. Its not the only way, but it works for me every time. This is my experience, others most certainly have different methods... but battery charger good cable equals win...

Ha ha I wish I had known, I've been at it for hours. Thanks for letting me know.
