i tried rooting my 820 just now. i followed all instructions. but when im about to safely remove my tablet or tried to eject my device "EJECT SAMSUNG", i get an error saying
"windows cant stop your android composite adb interface' device because a program is stil using ti. close any programs that might be using the device, and then try again later."
i dont know what using my adb coz i close cmd already using exit command. i tried unplugging the usb cable and checked my tablet via root checker, and the result was NOT ROOTED. i tried the whole process 3x but i cant seem to make it work. do you know any problem that might cause this?
thanks a lot!!
you need to use the command adb kill-server then you will be able to eject safely.
