I just did a factory data restore so that I could use my phone for testing.
But now I am trying to use the adb tool to put a new .apk on the device using my usb, and it says device not connected.
The phone is displaying this message: MTP: server status: connecting to computer...
But it is never able to fully connect.
I tried to go to Wireless & Networks, and enable Internet pass-through, but that option is also "Turning on..." for the last 5 minutes.
Any idea why I am not able to connect?
