adb shell su works but adb root does not


I rooted my unlocked Galaxy S3 (SGH-T999)

Now, I'm trying to run adb root from Windows Command Prompt, however, I'm getting adbd cannot run as root in production builds error. So, the very first thing I checked was whether my phone was really rooted?

So I tried the following:

Open Command prompt

$adb devices // lists my device
$adb shell //goes to shell
$su // opens a 'SuperSu' prompt on my phone and I 'Grant' permission
# // Before following the rooting instructions, I was getting 'no su command found' in the previous step. So, I believe my phone is ROOTED. **Correct me if I'm wrong.**

However, when I do adb root, I get adbd cannot run as root in production builds error. So, I thought, I might have to do some additional stuff beyond what I did above. I tried all the solutions in the following SO questions:

None of the above worked for me. All they do is give the ROOT access INSIDE of SHELL. I want adb root to work so that I can execute various adb commands WITHOUT going into shell.

In some developer-friendly ROMs you could just enable Root Access in Settings > Developer option > Root access. After that adb root becomes available. Unfortunately it does not work for most stock ROMs on the market.


I ran into this issue when trying to root the emulator, I found out it was because I was running the Nexus 5x emulator which had Google Play on it. Created a different emulator that didn't have google play and adb root will root the device for you. Hope this helps someone.


I use for enter su mode in abd shell

adb shell "su"


I have a rooted Samsung Galaxy Trend Plus (GT-S7580).

Running 'adb root' gives me the same 'adbd cannot run as root in production builds' error.

For devices that have Developer Options -> Root access, choose "ADB only" to provide adb root access to the device (as suggested by NgaNguyenDuy).

Then try to run the command as per the solution at Launch a script as root through ADB. In my case, I just wanted to run the 'netcfg rndis0 dhcp' command, and I did it this way:

adb shell "su -c netcfg rndis0 dhcp"

Please check whether you are making any mistakes while running it this way.

If it still does not work, check whether you rooted the device correctly. If still no luck, try installing a custom ROM such as Cyanogen Mod in order for 'adb root' to work.


You need to replace the adbd binary in the boot.img/sbin/ folder to one that is su capable. You will also have to make some default.prop edits too.

Samsung seems to make this more difficult than other vendors. I have some adbd binaries you can try but it will require the knowledge of de-compiling and re-compiling the boot.img with the new binary. Also, if you have a locked bootloader... this is not gonna happen.

Also Chainfire has an app that will grant adbd root permission in the play store:

Lastly, if you are trying to write a windows script with SU permissions you can do this buy using the following command style... However, you will at least need to grant (on the phone) SU permissions the frist time its ran...

adb shell "su -c ls" <-list working directory with su rights. adb shell "su -c echo anytext > /data/test.file"

These are just some examples. If you state specifically what you are trying to accomplish I may be able to give more specific advice
