A way to copy data from android? I have a samsung s4 on android 6.0.1 and the phone has a cracked and unresponsive screen. I tried to plug the phone to my computer so see if I could copy pictures from my internal drive but it wouldn't work. I tried  adb pull since I have root access and developer option was always enabled but I get error: insufficient permissions for device: verify udev rules.
adb devices  shows 9a22b563  no permissions (verify udev rules); see [http://developer.android.com/tools/device.html] I think this is happening because of my locked screen. It is stopping adb from working properly. Is there a way to get my data back by disabling the lock screen?
I have root and custom recovery access but unable to reboot to recovery due to adb not giving access.
You can manually boot to recovery without adb. Therefore turn your phone off and then press the power button, home button and volume up (at least as far as I remember) simultaneously for several seconds. This should boot the phone to recovery and you can try to use adb although I don't know if you now have the needed permissions.
