SU Binary In /system/xbin, But SuperSU Is Not Working - AT&T Galaxy Note 3 Q&A, Help & Troubleshooting

Besides the SU Binary In /system/xbin, what else do I need for SuperSU to function?
It keeps saying the SU binary is not installed

I was rooted on MI9 using the DLV method. I updated to NC2, and the SU binary installed by SuperSU persisted in the /system/xbin/ directory, but the SuperSU app says it is not installed. I wanted to know what, if anything, I can do with the SU binary in place to get the SuperSU app up and running again.

i am not sure there is anything you can do till we get a root exploit for nc2

yeah, i too have still have su in system/xbin on NC2, but root isn't working. it's weird, but as stated above, we probably need a new exploit or something

Are the permissions correct on the su binary? Might as well check that before we start despairing.

Yeah, I'm not allowed to set the permissions in Root Explorer without root, but it does show a preview and the permissions do match all the other files in xbin

Same here, permissions match all the other binaries in xbin.

I wonder what this means. I figure we dont need a new kind of su binary, but there must be something in the new software that blocks it from working?
I hope it isn't in the kernel. I had a Sony device last, and we needed an ever so slightly modified kernel in order to get full root on 4.3. But I doubt if we will ever be able to flash kernels.

I'm guessing there is some setting or permission that needs to be changed.

Why the root message isn't showed like Hero&Others ?

All others rooted phones have a message showed when an application asks root, why don't we have this on Tattoo ?
On Tattoo root permissions are always enabled
Ok, it's nice but we can't see which application ask root :/
Like Terminal Emulator, when you launch it, the shell is always in normal user "$", not in root :/

This is true, but I dont know how, after isntalling 5faif ROM, terminal emulator shows me the #, id command shows me that I'm root.
I'm on stock ROM, this is the problem i think!
Anybody has SetCPU ?
The problem with this is that every application can obtain root without our knowledge.
It is a serious security flaw.
Not really. Android is pretty secure. Even if you get a brick from a Andirus (Virus + Android), it's a piece of cake to undo the damage.

Because that rom you've flashed contains custom boot.img by mainfram3 that gives to you root at startup and loads tattoo-hack.ko (partition r/w always mounted)

Actually i wasn't having viruses in mind. More like keyloggers and such. SU prompt wasn't invented for no reason...
I think the OP was asking about SuperUser.apk.
It's a modified su plus a service that asks for user intervention when a program calls /system/bin/su. It's nifty and it should be used by everyone.
Android apps are prevented from looking into other apps data. If su is readily available, a app can escalated it's privileges and steal your personal info, by reading data from other apps.

Exactly my point.
MoDaCo Custom ROM 1 includes Superuser apk for root access.
P
Anyone know how to fix Superuser Permissions manually?
I have Tattoo with rooted boot.img (mainfram3)
I pushed su into /system/bin/
Made chmod 4577 /system/bin/su
Pushed superuser.apk from Modaco Rom to /system/app/
Restart sure...
SuperUser Permissions can be executed (list is clear)
But any app doesn't send request to Superuser Permissions.
What i could forget?
Finally, I solved it partially.
Sure, i have rooted boot.img
I extracted from Modaco Custom ROM for Tattoo:
su
Superuser.apk
copied su to: /system/bin/su
copied Superuser.apk to: /system/app
run in terminal: chmod 4577 /system/bin/su
restarted and everything works fine now... Superuser Permissions shows all root-requests, Titanium Backup works, other root-things works too
But i notice, that su-binary from Modaco ROM is about 34-36 kb, but
su-binary from guide of getting root is about 80-85 kb.
1-2 months ago we faced with difference in size of su. We choosed bigger su in case, what it can run "flash_image", smaller su can't run.
But maybe it fixed already? I did not test it yet.
Thanks @5[Strogino]
I was trying to use Titanium today to back up my apps but it didn't work.

What exactly wrote TB?
Did you download busybox via TB?
I don't remember exactly.
It did ask me to download busybox and I did that, but still it didn't work.

i used cmw method. i think it was a busybox installer for root
Binary updater fails to update binary – This usually happens because for Superuser can’t write to the system partition where the binary is installed. This can happen for a couple reasons. First, and most common, is that your device has S-ON which prevents the system partition from being written to at runtime. Even if a remount succeeds, and the system thinks that the partition is mounted as rw, you can’t write to it. There are different solutions for different devices, but the easiest usually involves simply updating Superuser through ROM Manager.The app consists of two parts, Superuser.apk and the su binary.The su binary is what other apps call when they need superuser rights. The binary checks the database maintained by Superuser.apk to determine if you have already granted rights to the requesting app.Superuser comes pre-installed on any rooted ROM. In fact, without it, you don’t have a rooted device at all. You cannot uninstall it, it lives on the system partition with other apps that came pre-installed on your device!http://downloads.androidsu.com/superuser/Superuser-3.0.7-efghi-signed.zip
Sounds like I have the same issue, here's my post on chainfires kernel thread:
http://forum.xda-developers.com/showthread.php?t=1331784&page=186
I don't like using CWM out of fear of the brick bug which probably only happens when wipe is used but have stayed away from the first few warnings we had.

Need quick help with terminal

So when I open up terminal emulator there is a '$' sign and I input the command "su". It says that super user granted permission. After that the '$' disappears and I can't do any other commands. If I enter one it will just skip to the next line with no effect. Can anyone help? Thanks.

I really want to try it out but for some odd reason none of my apps that require root works now. It must be something wrong with my Super user
Uninstall superuser apk and reinstall from market? Or try clearing the data of it

Try updating the su binary. Or try installing super su switching to super su's binary AND THEN uninstall super user. Or the opposite if your already using super su. You must NOT just uninstall the su app though. You must install the other, update the binary (instructions can be found in super su's thread in android apps and games (IIRC) the app itself, or Google it.
And THEN uninstall the other one.
Worth a shot.

I tried to update the Superusers binary but it gets stuck on trying to get root access. I installed Super su and it tried to install the binary but it doesn't seem to be able to finish updating. Any other alternatives?

Can't write on /system after root

I'm rooted with SuperSU 2.79 systemless on OOS 4.1.0 and I can't get permission to write on /system.
I tried using ES FIle Explorer and the option keeps changing to RO. I also tried via recovery. Root permissions are granted and It's properly root.
Any clues?

I had the same issue. I don't remember what I did. Try uninstalling super su from the app and then install it again.

Still nothing. For some reason permissions won't change.
You have systemless root?
If yes I think you can only modify data Partition. Maybe you need a magisk module?
Remove superSU and just go with Magisk. It works much better than SuperSU ever will. It's easily removable and won't adjust partition permissions, including system. Make sure you mount system in twrp before flashing any root access zip file as well. It helps prevent problems like this.
Fix To Grant ES File Explorer SuperSU Access Using Terminal Emulator
Start Terminal Emulator. Type su.
ENTER EXACTLY LIKE THIS: echo "BINDSYSTEMXBIN=true" >> /data/.supersu
Spaces.......................................................................................... ^....^.........
Make a backup first incase ****e goes south... This has worked for me on a couple of devices.
Standard disclaimer... Yada...
