Hubsan Official Forum

I read lots of posts concerning "won't connect after update"
I believe,and I may be wrong,that some folks simply ARE NOT waiting for Zino to "install drivers"before they are trying to update.
BE SURE to pay attention to your laptop. Let it say "drivers installed successfully"before attempting to do anything with your quad.
Simply plug Zino into a USB port,you will hear the "sound"telling you it has successfully linked.
Wait.....wait....wait....it could take up to 5 minutes,before the drivers are fully installed. THEN proceed

nothing to do with this, by the way the drone had connected ONE single time after 3rd or 4th upgrade, but just for 3 minutes.
if driver are not presents, drone will not connect, anyway in hubsan video they clearly states "connect the usb and wait for the tool upgrade to show connected"'...
