Thanks again for your help.
I have used Airdroid business, thats good i could detect the non rooted box.
But, I cant access it.
Normally, there are two steps.
1: activate the USB debuging by accessing to the development mode on the boxe.
2: connect the box on my computer by using a usb cable, a window should appears on my computer, to allow USB debuging, but no window appears.
Then I cant access to my box…but just showing it in the airdroid business…
Im trying to find a solution.
If you have any solution
Thank you Oxbo.
