Somebody help me please!!

The error message returned by Unity isn’t very descriptive, but I had the same issue today and it was caused because the device wasn’t registered for development. You can find information about how to register your device for development in the following link:

I have the same issue, again. Last time the problem was that I had too many (2) dev apps installed on the device. After removing one, it worked. This time it’s not the problem:(

I just recently got this, turns out my IpOverUsbSvc service had stopped, enabling this in the task manager made it work again :slight_smile:
