ADB error: cannot connect to daemon

Question

I need help to get ADB working on my PC (win7 64bit) with the Samsung Galaxy S2.

I have installed the drivers coming along Kies, I think under sub folder \"25_escape

Answer 1

Make sure that Kies is installed, but not running.

On your phone make sure you have USB Debugging mode enabled.

If still not successful, disable any Antivirus software.

Answer 2

I face this problem on daily basis, so to resolve this I kill adb.exe by executing following command :

taskkill /f /im adb.exe

Note : You should have administrative rights to execute the above command.

Answer 3

I was using Genymotion 2.9.0. I updated to 3.0.0 Now it is working. So please check Genymotion version.
