UE4 deployment on mobile samsung galaxy s7 error

Hi,
i wanted test UE4 project deployment on samsung galaxy s7. So i did all in the documentation page. I setup the mobile phone, i downloaded the android works, and i followed also the quck start guide with a blank project. But i get and error like this:link text

When i use android packing from UE4 it compleate it successful but when i start the .bat file it also gives me and error.
So the problem is the transfere to the mobile phone ? I set up all mobile settings like the guide. The only thing i dont know is that the device goes offline some times.

Need real help. Because this error occures also in vr setup. Its the same.

I solved it anyhow. On my pc i got different USB prots. 1 in front and more on the backside of the pc. Now i used one of this other USB ports and changed on UE4 Android create apk file. Probably one of the ports was 2.0 and the other 3.0. Also i changed phone to be all time on and not switch to stand by screen. It works now at least.
