Can't use superuser permissions?

I rooted my phone and installed Cyanogen Mod and as part of the process of installing it I made sure I had it rooted and had superuser permissions. Now, though for some reason whenever my phone tries to ask me for the permissions it says that the app superuser permissions has errored out and needed to be force closed. What could be causing this? I used unrEVOked to root my phone and it's worked fine in the past. Any ideas?

Go into Settings > Applications > Manage Applications > Superuser, then hit clear data. That may fix the problem.
If not go into Rom Manager > Fix Permissions, let that go through, reboot, and see if that worked.
If neither of those work I would try uninstalling and reinstalling the SU app.

Thanks a bunch. I went ahead and did them both so I couldn't tell you which one fixed it but thanks!

[Q] Superuser upgrade

I got a superuser update and while updating one day it updated succesfully.. now all of a sudden ts prompting update again and its not updating.. its throwing a update failed error message.
Anything that needs root access like titanium says cant get root acces..
whats going on?

The kernel you are using may not have the proper signature to update to the 3.0 binary. You can try the superuser update fixer from the market, and then update the binary, or just uninstall the new superuser from the market to revert back. I find the update fixer works temporarily for me untill I reboot, then it tells me to update binary again. I just reverted back for now.

I had a similar issue, where I would get something like "Obtaining root access: Failed" whenever I tried to update the binary file. I would also get a random FC of Superuser.
I uninstalled Superuser to get to the original one when I rooted my phone, and updated again via Market. It updated the binary file fine now. Hope that helps!
Note, I do also have Superuser Elite, but I didn't modify that at all.

Had this happen a while back. Just clear the su cache and re-try, that should fix the error

Lol works fine on the stock kernel.
(I keep telling people that stock has its benefits) lol

Check the market, they've been updating the Superuser app, like crazy the last few days. I've now had about 3-4 updates (at least one per day).

Uninstall the update then unistall the super user app. Reinstall the super user app, reinstall the update, and then try again. This worked for me.
I had automatic updates enabled, I think it screws it up. So uncheck it and manually update it whenever it needs to be.

Here's a quoted answer from http://forum.xda-developers.com/showpost.php?p=18212299&postcount=2646

The developer of su stated on his website that the binary cannot be updated if it is installed in /sbin, because that directory is actually a part of boot.img, which remains read only even if the system partition is mounted with read-write access. This is exactly how it is installed in SRF 1.2 (and probably all earlier versions, as well as several other Epic roms).
Rom developers will need to change the su install directory in order for the su app to be able to update the binary.

But if you're using a stock setup, perhaps one of the other answers here would be more helpful.

Superuser binary update - "Making sure new su works..." fail!

I use the stock 4.0.3 rom, rooted by flashing the su binary to system.
Now I updated to the latest superuser market app, and it sees that there's a new version of su binary.
But when I try to update to this new su binary, everything else goes fine, but when it reaches the last step "Making sure new su works...", it says "Fail!".
What's going on?

Problem
I HAVE THIS PROBLEM Too i contacted chainfire but he doesnt answer me back.

Same issue here as well. It still grants all my apps superuser privileges though. I wonder if it matters?

Should I make a flashable zip with the latest su? That would work.

Same, lost root after cm10 flash, su fail.

yes I'm having the same issue after flashing new ROM...but Tit Backup won't gain Root! ^^

Same issue.. The newest SU update is a fail. It's a total shock because it's always been solid in the past. We wouldn't be doing half the things we do on our phone without it

I also noted this when trying to update the binary on my GTab 7510. Only things I can suggest are choosing a ROM that has the latest Superuser + binary included, re-rooting with a newer root package, or uninstalling the update (although you constantly get the update notification which is annoying).

Same thing used to happen to me whenever I would try switching from SuperSU to Super User. Seems like SU anything from the market doesn't play nice with our phones.

i just reflash a root zip or superuser zip and that usually fixes it for me. no idea why its happening though.

How to change SuperSU to Superuser?

Im currently running JMT which uses SuperSU. I would like to use Superuser. Ive tried just flashing Superuser, but how to remove SuperSU?
I posted this in the ROM's thread, but never got an answer so hoping someone here will know

Delete the Superuser.apk in the ROM (it's really SuperSU) and pull the "real" Superuser.apk from somewhere else.

I did so (system-->app), installed superuser, rebooted, cleared dalvik and fixed permissions...still getting the supersu shell message with apps, and still showing up on installed programs...what did I miss?

I'm curious, but would it just be a matter of updating the binaries with Superuser?

Well, I downloaded a fresh copy from the market, and when I open it it doesn't update. Just shows no apps are assigned to it..

Um, even easier...
Download SuperUser recovery flash zip and while still inside Android on device go to file manager open /system/apps and delete the SuperSU.apk
Now restart to recovery clear the cache and dalvick cache
choose install from SDCard
Find where you downloaded SuperUser.zip and flash
Restart
SuperSU is WAY better at handling Super User requests [for instance, it has a wait state on the pop-up where it does not go quite as fast so some apps that take a min to request super user and another min to display the pop you aren't already at 1 - 2 seconds] and for instance for quite some time Super User was known to seg fault [basically an error happens and it doesn't work to grant access right when that happens] whereas SuperSU was created later to kinda address that and some other issues in SuperUser [not saying SuperUser is bad it is updated and does it's job, it's just SuperSU does it better].
Just if any guide says use SuperUser just replace SuperUser with SuperSU when doing something and in app drawer just look under SuperSU for it's app and not SuperUser.

Thanks for the help and input guys

Can I do this with replacing Superuser with SuperSU (I'm running Avatar ROM & I miss using SuperSU)?

[Q] superuser and 4.3

I am constantly having issues with the built in superuser app in most 4.3 roms (in settings) and /system and "sdcard" storage... is there any way to update the built in su binary?
Right now I'm stuck installing supersu instead to get things to work right. I'd prefer to use the built in superuser though to avoid conflicts
On a side note, why do most roms include the most incompatible superuser app for 4.3 anyway? (I've found supersu works best, followed by superuser from the market with only a few issues, and the built in one does not work well at all with 4.3)

I dont know if you can change anything about superuser.. But you could have a look at developer settings. There are some settings regarding root access..
They use superuser because its open source. Supersu isnt (as far as I know)
