I installed the leaked ICS update, but I have apparently lost root. I tried using Voodoo, but it just says that it has been denied Superuser permissions and that there is no root backup available.
So I tried just plain rooting it using the Motofail method again, to no avail. It says that it is successful in completing the exploit.
However, no matter what app that requires root that I open, it says that the app has been denied Superuser permissions without even prompting me. Root checker says I am not rooted.
I went into the Superuser app, and I went to update the SU Binary. It says that Superuser has been granted Superuser permissions. But then it fails out at the end and says "This updater cannot update the su binary on phones that have some kind of write protection like S-ON. You can continue to use Superuser with your outdated binary, or update su with ROM manager."
I shouldn't even need to update the binary though, since it says I have the latest one installed.
What can/should I do? It's getting kind of annoying not having root on my phone.
Something along the same line happened to me too bro,I also made a thread about it but to no avail:-/ if you find something out,let me know and I'll do the same.

Try this on ics terminal
Code:
./system/su-backup
mount -o remount,rw /dev/block/system /system
rm /system/bin/su
ln -s /system/su-backup /system/bin/su

So if you dont have root access, will the terminal move the unzipped su file? How can you apply this to your sysytem? Voodoo doesnt give you options to search for the file either. Of course, nothing has superuser permissions without root either. I guess Im too much of a n00b.
Same here
Na dude its not noobish,im tryna figure out everything myself,I've been flashing since the hd2,so i know a couple things but this is just mind boggeling lol
I'm at a loss. I've downloaded your su-backup file, but I don't know how to move it to the /system folder, as it is write protected, and I don't have root to bypass that. And whenever I tried typing things in using the terminal, it just denied everything.

You can't move this file to system folder because you have a non-rooted device. Be patient, we are working hard on that....

SU is in the app list, as in the App Drawer? You mean SuperUser if that's what you're talking about. SuperUser is the GUI interface to the actual su binary.
The su binary (which should be located in /system/bin on the phone) is the actual file that grants root access rights. Can you confirm that that file has actually been installed and what its permissions are?
Will the SuperUser app let you download/update su? Also, you should be able to install it from CWM under the extras menu if I recall correctly.
My phone's not handy to confirm above, I'm doing by memory, which isn't so great these days, but hopefully this will give you some ideas of what's wrong.

i cant atm i dont have his phone. SU (superuser) is in the list, and it told me it was up-to-date when i tried updating it.
CWM? thats new to me atm
root checker sees busybox, but reports not rooted.
My Razr Maxx installed the OTA ICS update today. There were no error messages. Everything seemed to run fine. And on top of that I thought that my root was preserved.
Well, I have an old version (3.0.3.2) of SuperUser intalled that I cannnot uninstall. I cannot mount /system/ as read-write using ADB. I can't mount /system/ as rw using Terminal Emulator on the phone. I tried the one-click script EternityProject EasyRootICS to install root and it seemed to work (no errors reported), but when I edited the batch file to get rid of all of the CLS (clear screen) commands, I was able to see that when it tried to write the new superuser app to /system/bin/ it's failing (with no error reporting).
So what do I do now?
The bottom line is that I need root, but I don't know how I can get root without getting rid of my old SuperUser installation first.
I have the exact same problem..... I can't get rid of Superuser, but I can't get access too use any root applications. SU denies all of them...
Go to this link here and where it says "Note: If you don't get root by other method root attempt with su and Superuser.apk already installed." download from that link.
http://www.mod2xtreme.com/showthread.php?13332-TOOL-ROOT-Razr-EternityProject-EasyRootICS-Win-Linux
It helped with Superuser not working properly.....
I should have replied to the SuperSU thread but since I have less than 10 posts...
I was doing a fresh flash/install. The first thing to do of course is to root the phone.
Installed SuperSU 0.94, open it up, says that I need to update the binary, clicked OK, Installation Failed, tried that several times via 3G/Wifi.
Tested under Better Terminal, typed su: not found.
Then I installed Superuser 3.1.3, run SuperSU again and the binary update worked.
Tested under Better Terminal, typed su: # it worked.
Uninstalled Superuser and tested under Better Terminal
SU gone again.
The binary update failure happened before when version<0.7.3.
So why is this? Why do I need to install Superuser to get SuperSU to work?
It depends on what su binary is installed when you root your phone or what app the author of the ROM prefers. You can download the supersu zip package and install it after you install a ROM but even then you'll have to update binary via launching the app itself.

Because every app that uses Superuser permissions needs a a management app to get access to su.

Oh, by Supuruser I'm talking about Superuser - the old app, not the superuser permission.

Yep, you're right, I was just stupid not paying attention to the bat root script. I removed the old Superuser.apk from the scirpt but not the binary.
When I replaced the su with SuperSU binary, no errors anymore. Thanks.
I'm new here but have been messing around with android for awhile. I spent all afternoon searching for an answer but haven't been able to find anything. I had rooted my prime but not unlocked it while it was on ics, I used ota rootkeeper to keep root when I upgraded to jb but i think when asus sent out another update i forgot to save root. I still have su in /system/bin and superuser installed but it won't prompt me to give any programs root access. I typed in su in a terminal emulator and it said permission denied. so my question is, how do I get root back without unlocking?
Does this thread help ? http://forum.xda-developers.com/showthread.php?t=1911261&highlight=partial+root
I was able to get root back back doing something similar. Somehow the permissions got messed up for su. I went into adb and got root permission through CD/ system then ./usr/we-need-root/su-backup; su. Then I pushed new su, busybox, and superuser.apk files and fixed the permissions and changed the owner of su using chown and chmod.

I rooted my strange tablet using Kingo and apparently it was succesful:
http://i1312.photobucket.com/albums/t539/talos910/Screenshot_2015-09-11-17-08-20_zpsurdgzj8p.png
But I have been trying for days to erase a file in /system and I have not been able to do it, I think I have read every relevant thread about this problem but no luck, I tried using ES and changed /system to r/w in the root options but when trying to delete the file all I get is operation failed, the same happens with all the other root explorers and tools. I even tried the solution on this thread: http://forum.xda-developers.com/ascend-p7/help/edit-replace-write-files-set-immutable-t2884172
but still can't delete it.
Also the app root toolkit for android gives me this weird error too:

Do you have an app like root explorer that specifically asks for root permissions? It doesn't matter if you have root if the explorer can't use it
Sent from my Nexus 5 using Tapatalk
Yes all the file manager apps I used always ask for root permission, that is the problem they have root permission but still can't delete the file, which is weird because I can use apps that definitely need root like scr screen recorder and greenify just fine.
Try installing root explorer and then attempt to delete the file, then it should instantly open a window asking for root. The of course grant the permission. That should always work, but if it doesn't just restart the tablet, if it still doesn't work it must mean you are deleting a file that is in use by the system. Otherwise i have no idea whats wrong

Rooted my device using kingo root, I didn't intall other recovery.
Bad idea to try and remove system files without a custom recovery and a nandroid backup made and stored in a safe spot. What are you trying to remove?
I am trying to delete /system/sbin/su because I read in another thread this was the solution to fixing the issue of the app supersu not updating binaries when rooting your device using Kingo.

That is the binary. If you remove it, you wouldn't be rooted. Can you link the thread you are looking at? There's an app made specifically for replacing that su binary with SuperSU and it's binary called Super-SUme, though I believe it is a paid app.
I know it is the binary but according to this guy:
http://forum.xda-developers.com/apps/supersu/support-update-failures-t2907365/page23
(post 223)
""It appears kango wrote to /system/sbin/su whereas supersu wrote /system/xbin/su and subsequently supersu would keep wanting to update 'su' then fail.
The long and the short of it is once I manually removed /system/sbin/su supersu stopped telling me 'su' was outdated. I don't know android but I do know linux.
$PATH on my tablet has /system/sbin/ prior to /system/xbin/ so it would appear supersu is issuing 'su -V' as opposed to '/system/xbin/su -V' when it checks the version. The kingo 'su' was older than the supersu 'su'.
Dunno what the solution is 'cos the older 'su' is going to get called first & I figure there's nothing but trouble to be gained from changing $PATH globally. Nevertheless it might be enough to check $PATH for unwanted 'su' and flag them, possibly offer to remove them? In my case I renamed it "/system/sbin/su.ORIGINAL" so that it's still runnable in an emergency"""
If you rename it, it won't be able to run, and won't require removal.
That's the thing I can't rename the file either for some reason. Using es and other root explorers doesn’t work.

Seems like the SU binary that Kingroot included is pretty finicky and only works for some things. I've rooted 100s of devices and have never had issues like that. Have seen complaints about other various oddities with Kingroot too. It's nice that it's easy and works on a variety of devices, but if you have only limited control then that kind of defeats part of the purpose of rooting it...
Tried using SuperSUme but the app says I am not rooted with Kingo? wtf? Do you guys know of any other reason why i can't erase the system file sbin/su?

With Root Explorer, does it let you set the system to R/W? There's a little button at the top of the app that will say R/O or R/W for Read Only or Read Write. If you don't have R/W to the system, then you are unable to make changes to it.
I just renamed file su and then it became able to be deleted.

Connect your android tablet device to your windows computer. Then enable usb debugging on your android tablet. Then open the windows program called cmd. Then do these commands.
Code:
adb root
Code:
adb remount
Code:
adb shell rm /system/sbin/su
