I recently won this developer tablet and I can't seem to get on-device root access. It came with su binaries installed. (very old ones but I updated it) It also has an unsecured kernel because ADB always runs as root. However I installed superuser and it can't get root access and when other apps attempt root access something seems to be denying access before the superuser prompt is even able to come up. Just curious if anyone has any ideas??

This may seem like a stupid suggestion but I suppose you could try uninstalling the superuser app and use Chainfire's Super SU app to see if that might make any difference.
Tried that too lol. I was even able to go into old su app and toggle permission for super su to allowed and it still said fail when it tried to update binary. Thanks for the suggestion though. It seems to me the problem is that the chown and chmod commands are not sticking on the su binary. They appear to work but the actual ownership and permissions of the file don't change. Even when I do adb remount first.
I figured it out. For some reason I had to put the su binary in /system/bin instead of xbin. Which is strange because all my other device it went in xbin. Also the reason the chmod and chown commands were not working properly is because I forgot to do adb remount. (duh!) In case anyone is wondering this thing is a beast. I just wish I could figure out a way to get my Gameloft games to work. I (mainly modern combat 3 and nova3)

One way to get your games to work would be try side loading the Modern Combat 3 and Nova 3 APK's onto the device and installing them manually that way. Another way if that doesn't work is you could try modifying your build.prop and changing your product id to match the galaxy nexus that way the play store will think your on a galaxy nexus and it should say that the games are compatible then.

I know this is an older post but I'm at the same point where I can't figure out how to allow superuser access. I'm using the 8064 for research and I need the root access but can't seem to figure out how to update the SU. Any tips?

Do you have the Superuser.apk app installed along with the SU binary in the correct place /system/bin as mentioned by JBO1018? If you already had working root access before on the device and just need to update the SU binary you can open the Superuser app, then go under the info tab and tap on the SU binary version number this should then check for updates and then ask you if you want to install any found updates.

I have both the Superuser.apk and SU binary in the right place. Each time I open up an app that needs root access a toast message pops saying that the app has been denied Superuser permissions. I tried restarting both apps but its not working.

Try going into the Superuser app and under settings and then security the default behavior is set to prompt not deny.

Hi XDA Community,
Your forums have helped me in the past and I spent some time scouring the posts before posting this one as I couldn't find anything that was specific to my issue. Since this is my first post, I thought that I would save a ping pong of responses, by being fairly expansive on what the problem is and what I have tried; thus hoping to pinpoint my issue a little quicker.
Device Details:
---------------------
Model Number: GT-I9100
Android Version: 4.0.3
Kernel Version: [email protected] #3
Build Number: IML74K.XWLP3
ROM Firmware: Samsung-Updates.com-GT-I9100_O2U_1_20120326173406_jiut50pyip.zip (via Samsung Kies)
Rooting Method / Kernel: Odin3v185 / CF-Root-SGS2_XX_XEO_LPQ-v5.3-CWM5
Summary
--------------
Since the beginning of July 2012, I successfully upgraded from Gingerbread v2.3.6 to ICS v4.0.3 using Samsung Kies then initiated root privileges by using the CF-Root Kernel via Odin (versions shown above) - All has been working fine 100%.....
However, it appears that I seem to have lost my SU permissions and may have disabled my root access, even though my device was rooted and I would appreciate any assistance from anyone who might have time to shed some light on the situation.
Behaviour of Apps I have tried that require root
-------------------------------------------------------------------
SuperSU
SuperSU Pro v0.96 lists in the 'Apps' tab (denoted by a green # symbol) that I have granted all relevant Apps that require SU privileges. This includes AdFree, BusyBox Pro, Root Checker Basic, Root Explorer, SetCPU, Terminal Emulator, Titanium Backup, Triangle Away.
Terminal Emulator
Terminal Emulator displays the following and when I enter the su command at the prompt, I just see a carriage return with a grey block. In other words, I do not see the # symbol denoting I have su privileges.
a/local/bin:$PATH
[email protected]:/ $su
Root Explorer
Root Explorer no longer displays a directory listing and simply displays a pop up from SuperSU after tapping on Root Explorer, "Root Explorer has been granted superuser permission for an interactive shell." then the following message from Root Explorer itself:
"Root Explorer has not yet managed to obtain root access. Because of issues with Superuser, this often happens the first time the app is run but is usually fine from then on."
Root Checker Basic
Apart from the App stating "Please wait for Root Check to be complete. Systems appears to be running very slow" after tapping on the [Verify Root Access] button. It never seems to provide an output after a few minutes waiting. My conclusion is that it cannot get su permissions.
BusyBox Pro
SuperSU displays the message that Titanium Backup has been given root access, however I get the following message:
"Asking for root rights..."
Then after a few minutes I receive this most enlightening output:
"Sorry, I could not acquire root privileges. This application will *not* work! Please verify that your ROM is rooted and includes BusyBox and try again.
This attempt was made using the "/system/xbin/su" command."
I read somewhere that Titanium Backup uses it's own BusyBox installation and not the system wide BusyBox package so I went in to the Titanium Backup preferences and selected 'Troubleshooting settings' then chose 'Force system BusyBox' to see if my issue was a BusyBox specific problem. Again, it failed so not sure if it is BusyBox or my SU permissions that have somehow got corrupted or been disabled.
Additional Information
-------------------------------
Using 'ES File Explorer', I can confirm that the following file's exist at the appropriate location paths:
/system/xbin/su
/system/xbin/busybox
Conclusion so far
-------------------------
It appears that on the face of it that I have lost my root permissions, so I removed apps from SuperSU, then uninstalled the App (e.g. Root Explorer, Terminal Emulator et al.); then performed the rooting procedure again via ODIN and the CF-Root kernel. The process itself worked flawlessly and so after it rebooted, I installed the Apps in question from the Google Play Store again and they prompted to be granted SuperSU privileges. Unfortunately, the same issues arose where it appears that it cannot communicate with either the su command or BusyBox to do what it requires.
Does anyone have any ideas as the phone is fine apart from this and although performing a Titanium Backup backup around two weeks ago, I would sooner not have to wipe everything if I can help it. I wonder if it is an update that somehow confused things...Either way, I cannot use Titanium Backup to backup/restore due to it requiring SU/root permissions, of which I do not seemingly have anymore.
Any ideas please as I am scratching my head and have gone blurry eyed at spending hours viewing various forums and posts?
follow this steps:
1. Unroot your phone with the unroot method here
2. To be sure, unroot again with the method here
3. ROOT your phone again using Any of the Rooting methods in the links provided in step 1 or 2.
Good luck
ICS 4.0.3 Lost su permissions even though device was rooted - Resolved
:good: Issue Resolved :good:
Many thanks for contributing to my issue. I had come across the post before in your links and although the directions were not completely related, there was a section pertaining to a zip file that I must have missed.
Conclusion
----------------
As can be read in the post, I was unsure if my issue related to losing root, a possible corrupt su file itself or BusyBox. As you will see on the link below, Busy Box actually creates hundreds of symbolic links (symlinks) and due to my perhaps overzelous approach to wanting a quick fix; I must have inadvertently created too many links with different versions of Busy Box and therefore when an App that was correctly added and granted SU permissions within SuperSU, when it then communicated with Busy Box / su to authenticate; I can only imagine it got confused and was lost with all the dead symlinks. The net result was that although SuperSU stated that it had granted permissions to the Apps requiring root, it never got to communicate with the su file contained within /system/xbin. I hope that makes sense, well at least I am pretty sure that is what happened.
Solution
------------
Firstly, I cleared all entries contained within SuperSU and therefore removing all Apps from being granted with root access (they didn't have it anyway at the moment).
I saved the zip file contained at the following link on to my external SD card and choosing to 'install zip from sd card' within the CWM Recovery (Volume Up + Power + Home button); effectively this uninstalls Busy Box completely from your device, including hundreds of symlink files - including many which in my instance was causing issues with Apps that required root to function correctly.
Busy Box Uninstaller v1.0 here
I restarted my device and downloaded Busy Box from Google Play Store and when I opened Root Explorer and the other aforementioned Apps shown in this post, they prompted to be granted root permissions (SuperSU) and voila....it worked ! :good:
I hope this may help other droid users experiencing similar symptoms.
i am trying to root some cheap tablet. its based on arm9 wm8800 dual core ,running android 4.4. in developers options there is option to set super user permission (always ask,etc) but it doesnt do anything,when i ran root checker it shows its not rooted,and when i installed superuser from play store it says something about SU binary also apps that require root wont work etc.. so i tried several other options.. after running z4root there's no more su binary problem. root checker shows its not properly rooted,it shows that su binary is there in system/xbin/su but there's red text with some permissions .like i need to fix them,but dont know what to do.. i have rooted many devices,but this is hard.. any help??
I'm pretty sure this is the latest version of SuperSU, but every time I reboot my phone I get a message that reads: "The SU binary needs to be updated!", and when I click on the prompt to update it, it always fails and asks me to reboot.
Has anyone else run into this issue, or know how to resolve it? Thanks.
SuperSU APK and the SU binary are two different things :
SU is a binary executable, it's used by Android and other *nix based systems to allow a process to change the user it is run by and therefore what the process has the rights to do (as it inherit the user permissions). In the rooting case, processes invoke SU to switch to the root user therefore acquiring root permissions.
SuperSU is an Android application (.apk is an Android application package), it works as a sort of "gatekeeper" to the SU binary. Applications which attempt to invoke SU will be forced to route through SuperSU, which will then prompt the user with the options of approving or denying the access to SU (and optionally having SuperSU remember their decision and automatically apply it for subsequent calls by that app).
So what happens to you is, every time you boot, SuperSU v2.78 (which is the latest version of the SuperSU APK) checks the SU binary version and tells you that there is a newer version of it and that you should update it.
Then for SuperSU failing to update the SU binary I can't help as for me it always worked till now. But maybe there is a way to manually do it (by finding the binary in a flashable zip that you can flash in recovery)?

Thank you for explaining the difference for me. I went ahead and downloaded the .zip from here: http://forum.xda-developers.com/apps/supersu/stable-2016-09-01supersu-v2-78-release-t3452703/page8
And then used the installation instruction found here: http://androiding.how/how-to-flash-supersu-using-twrp-recovery-and-root-any-android-device/
And I don't seem to be getting the prompt that SuperSU needs to be updated anymore.
Huh. Never mind. Seemed to work for about 12 hours, but now it's asking me to update again, and I can't. Looks like I need step-by-step instructions on how to clear this message, cause whatever I'm doing isn't doing the trick.
Did you disable Sony RIC and dm-verity when you modified the kernel? I'm not sure if it has anything to do with or whether it will solve your problem, but one time I patched my kernel leaving one of the options enabled and ran into all sorts of problems with apps that required root, so after that horrible experience I decided to just disable everything. During that horrid experience, I think I also had SuperSU (or was it busybox?) complain about not being able to update binaries.
Hi,
I need to root a Zebra TC56 to install some other apps that require rooted Android. There is very little information in the way of rooting the Zebra TC56. I 'm pretty set on using Chainfire's superSU, but I cannot find any information on whether it will work on this hardware. Does anyone know if the superSU works on this device with Android 6? If not, is there another Root Tool that will work.
Any advice appreciated.
THANK YOU!

1. Install BusyBox applet-suite what contains the SU-binary
2. Install latest SuperSU APK

BusyBox installed fine.
SuperSU will not install all the way. When I select to root, it says root not detected and then, "How to Root", which launches my browser to a site that no longer exists.
Now what?
Thank You!
edit: Still stuck at this point. I read about TWRP, KingoRoot and some other random apps. I cannot brick this touch computer; it is $1600; that would be a very expensive brick. :crying:
So, I have no idea if I am right, but maybe I need to open the terminal emulator and "su" install the SuperSU apk. But I have no idea and I don't want to experiment. Hopefully, someone can help me.
@vidarr_kerr
Don't confuse things:
SU is the super user who unrestrictedly can perform any operation on Android OS. As soon as SU got installed Android is rooted! Again: BusyBox you successfully installed contains the su applet.
SuperSU is merely a root-manager app: it maintains a database where is stored what app can act as super user. SuperSU app doesn't grant super user rights.
BTW:
TWRP has nothing to do with rooting device's Android, as this is also true with Magisk.
The device is still not rooted after the "BusyBox Installer (No Root)", from your link, was installed.
I installed BusyBox, I followed the directions to then copy a command, then open a terminal, paste the command in and hit enter, then nothing happened. SuperSU was not installed with it.
So, as you told me, I then installed the latest SuperSU APK from your link. It says it installed, but when I run it, it says root not detected and then has a link named, "How to Root", which launches my browser to a site that no longer exists.
I followed what you said. Where did I go wrong?
Thank You!
You didn't get it. Sorry to say this.

Didn't get what?
I installed the BusyBox you gave me the link to.
I semi-installed the SuperSU you gave me the link to.
SuperSU did not fully install, because the Android is NOT rooted..
BusyBox had no SuperSU as part of it --the file you said to use even says "BusyBox Installer (No Root)".
(That should have tipped me off right away you had no clue, but I thought maybe you knew something.
So, you gave me the links for both of those files and it doesn't work.
I don't think you have any idea what you are doing; and shouldn't be explaining things you do not understand.
The "no root" BusyBox, does not include SuperSU.
If it did, why did you give me the link for the separate SuperSU file?
All the "no root" BB did was install a terminal emulator (with no su abilities).
The SuperSU didn't install, because the Android is NOT rooted.
If the Android WAS rooted, SuperSU would run and allow me to grant su privilges to the apps that require it to work.
You basically just wasted my time.
I would have just said "thank you" and moved on, but you are rude.
You don't know what you are talking about either.
Hopefully, this will help others, to not do what you say to do.

You're right: BusyBox (No Root) doesn't come with SU-binary. Wasn't aware of this. I misinterpreted APK's title. Pitty.
ERRARE HUMANUM EST ( To err is human ).
Installing BusyBox containing SU-binary requires your device's bootloader got unlocked before, because Android's /system partition gets modified. Hence manage to unlock device's bootloader as 1st thing of all things. Good luck.
DL BusyBox latest: https://github.com/meefik/busybox/releases/download/1.31.1/busybox-1.31.1-46.apk
My last 2 cents here: SuperSU and SU binary are totally different things.
