Just yesterday my adb was working fine and I was developing my app in peace... Today I updated my xperia z3 to lollipop (auto update from sony)... And the adb stopped detecting the device (on mac os yosemite).

What I checked so far: 1) I have the latest version of android sdk installed 2) I tried adb kill-server and adb start-server 3) I double checked developer mode is enabled on device 4) I double checked that USB connection is in Mass Storage Mode

Nothing works! Please help.

Go to Settings -> Xperia Connectivity -> Usb Connectivity -> Usb connection mode -> Check MTP mode.

Click Revoke USB debugging authorization in Developer option.

And try sudo adb devices.

  • Doesn't work :( Although Sony Bridge for Mac does detect the device and said it's connected... Tried with sudo and without sudo, MTP mode... Still nothing. Thanks for advice anyway! Maybe I need to wait for someone who had exactly the same problem... – akuz Apr 16 '15 at 11:41

    Click Revoke USB debugging authorization in Developer option and try it again. – Sukumar Nagarajan Apr 16 '15 at 11:46

    Needed to use adb kill-server before running sudo adb devices as well but worked once I did – Woodi_333 Apr 24 '15 at 14:42

    Ran into same issue here. I didn't need to revoke anything, just (re-)enable "USB debugging" in the device's developer options; it seemed to have been disabled by the upgrade. – timday Jun 15 '17 at 14:45

I had the same Problem on my LG G2 mini. I solved the problem through installing the LG software LG PC Suite on my computer.

How I did it: Open the connectivity settings in the drop-down menu of your device, when your device is connected to your computer. Open the settings in this window (top-right corner). In my case I was able to install the named software on my computer, when choosing the install item.

You need to install the device drivers or re install the drivers. Or I think you should upgrade drivers through internet.

  • Thanks! I have the latest drivers. It was the "debugging authorisations", please the the other answer. Thanks for your help anyway! – akuz Apr 16 '15 at 11:50
