I would like to add a little more explanation to @user837048's answer. on my OSX Yosemite and Galaxy S3 which is rooted and using firmware CyanogenMod 11 and KitKat I have done the below proceedings to Enable and Disable root prompt.

Please make ensure below

On your system
- Make sure you have installed Android SDK and you have set paths to binary files. type which adb on your shell. It must give you somewhat result. $ which adb /Applications/Android Studio.app/sdk/platform-tools/adb
On your Mobile
- Settings > Developer Options> Android Debugging = ON
- Settings > Developer Options> Root Access = Apps and ADB

If you don't see Developer Options in your settings, Goto Settings > About Phone. Scroll down to Build number and tap there 7 times. I know its crazy. But believe me it works :D

Connect your phone via USB Cable. type on your computer's terminal

$ adb shell

you will see a prompt similiar, If any prompt has been shown on your mobile, to trust the connection, tap 'Always Trust' and 'OK'

shell@m0:/ $

now type

shell@m0:/ $ id
uid=2000(shell) gid=2000(shell) groups=1004(input),1007(log),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats) context=u:r:shell:s0

See you are not root

Now exit from shell, which will fall back to computer's prompt

shell@m0:/ $ exit

Now activate root

$adb shell
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
root@m0:/ #

Wow.. you are root

root@m0:/ # id
uid=0(root) gid=0(root) context=u:r:shell:s0

I tried many solutions to go back to normal non root prompt. But didn't worked except @user837048's solution.

root@m0:/ # stop adbd && setprop service.adb.root 0 && start adbd &
[1] 32137
root@m0:/ #
$

This might exit you from Adb prompt to normal prompt. Now connect again.

$ adb shell
shell@m0:/ $

Well.. You are Non root

For quick steps just check summary  If interested to know details  go on to read below   adb is a daemon  Doing ps adb we can see its process   shell grouper     ps adb USER     PID   PPID  VSIZE  RSS     WCHAN    PC        NAME shell     133   1     4636   212   ffffffff 00000000 S  sbin adbd   I just checked what additional property variables it is using when adb is running as root and user   adb user mode    shell grouper     getprop   grep adb                                           init svc adbd    running   persist sys usb config    mtp adb   ro adb secure    1   sys usb config    mtp adb   sys usb state    mtp adb    adb root mode    shell grouper     getprop   grep adb                                           init svc adbd    running   persist sys usb config    mtp adb   ro adb secure    1   service adb root    1   sys usb config    mtp adb   sys usb state    mtp adb    We can see that service adb root is a new prop variable that came up when we did adb root   So  to change back adb to user from root  I went ahead and made this 0  setprop service adb root 0   But this did not change anything   Then I went ahead and killed the process  with an intention to restart the process   The pid of adbd process in my device is 133  kill -9 133   I exited from shell automatically after I had killed the process   I did adb shell again it was in user mode   SUMMARY    So  we have 3 very simple steps    Enter adb shell as a root  setprop service adb root 0 kill -9  pid of adbd    After these steps just re-enter the shell with adb shell and you are back on your device as a user

adb kill-server and adb start-server only control the adb daemon on the PC side  You need to restart adbd daemon on the device itself after reverting the service adb root property change done by adb root      adb shell id uid 2000 shell  gid 2000 shell      adb root restarting adbd as root     adb shell id uid 0 root  gid 0 root      adb shell  setprop service adb root 0  setprop ctl restart adbd      adb shell id uid 2000 shell  gid 2000 shell

If you used adb root  you would have got the following message   C   gt adb root   daemon not running  starting it now on port 5037     daemon started successfully   restarting adbd as root   To get out of the root mode  you can use   C   gt adb unroot restarting adbd as non root

This is a very common issue   One solution is to kill adb server and restart it through command prompt  Sometimes this may not help out   Just go to Window Task Manager to kill adb process and restart Eclipse   Will work perfect
