On my newly compiled Android 2.2.2 build, whenever i type "su" in the terminal it says:
link_image[2033]: failed to link su
CANNOT LINK EXECUTABLE
I tried everything possible, I have busybox working, but not su. I have the su binary in the /bin folder and correctly symlinked to the /xbin folder and the permissions correctly applied in the update-script but it still will not execute. Any solutions?
Anyone.. (bumped because of massive amount of threads created each day in this section..)
Having recently bought an ePad V2, it was my first introduction to Android. Therefore having rooted, upgraded firmware, etc I've hit the same issue in trying to get Root Explorer working.
I've found a potential fix at h**p://zenpad.doubtechdotcom/?p=50 but haven't had chance to give it a go yet. You'll have to fill in the gaps of the URL as this is my first post and won't let me give external links.
Ignore my last post as I sorted my problem (originally being unable to mount R/W in RootExplorer). Here's what I did:
1. Uninstalled RootExplorer and Superuser.
2. Unrooted using Universal AndRoot.
3. Rooted NOT installing SuperUser.
4. Installed Busybox Installer from Market (noob fail as I never installed it before!).
5. Installed Busybox.
6. Installed latest version of RootExplorer.
Now I can mount R/W in RootExplorer and therefore I'm guessing my SU problem has gone away.
Ok, so this is the problem:
I have a TF101, rooted since 3.2. I have been able to do OTA updates without problems so far, keeping my root with OTA Rootkeeper.
Last week, I tried figuring out how to automatically mount cifs-shares through Tasker. Whatever I tried, the share would not mount through Tasker. It mounted without problems through command line in Terminal Emulator.
Eventually, i narrowed it down to a root acces problem in Tasker, or the Locale Execute plugin, or the secure settings plugin. I noticed that neither of those had ever asked for SU-acces and there were no logs of it in the Superuser app. When downloading other root-needing apps (e.g. rootchecker), I had the same problem: whenever a new app would normally ask for root acces, instead of the usual Superuser-prompt, the app stalled for a few seconds and then gave an error message or just plain nothing. There was no log of this in the superuser app.
When setting the superuser app to 'always grant root', the situation stayed the same: new apps didn't get root, older apps still had root without problems.
While searching for similar occurences on the internet, I saw a suggestion somewhere to clear the cache and data for the superuser app, so I did.
Now superuser still doesn't prompt and NONE of my apps have root. Apparently even the superuser app itself has no root acces anymore, since it fails to get root acces when updating the su-binary.
My guess was that completely removing su and the superuser app and subsequently re-rooting the whole thing would fix this.
I tried unrooting/rerooting through various methods (Brk, Vipermod, this one, and the new Wolf's thingy), but to no avail.
Brk tells me eveything worked fine, but changes nothing, except it gave me an even older version of the su-binary.
Vipermod hangs on "daemon started succesfully" but apparently does nothing even after 10 minutes.
The Asus Backup Utility method changed absolutely nothing
The Wolf's method looked promising, but installing the "Superuser-3.0.7-efghi-signed.zip" failed. (maybe because I did this from CWM recovery instead of his recoveryblob recovery? Dunno.)
So far I can't seem to remove root, as OTA Rootkeeper assures me the superuser app is installed and the device is rooted, even if the root acces is not granted to it (or any other app).
Any ideas?
Update: tried installing SuperSU from CWM recovery to replace Superuser app, but it gave the same 'installation aborted' message. Is this because CWM has no root acces also?
update2: I have root acces through adb shell apparently. I looked here and here for a way to replace the superuser app. I managed to remount /system, delete Superuser.apk and push the Superuser.apk and su from "Superuser-3.0.7-efghi-signed.zip" onto the device.
No apparent change, not even in the su binary version number reported by Superuser app.
I downloaded the standalone su-binary from here too, and replaced /system/bin/su with that one, too, but after reboot the Superuser app still indicated su binary version 2.3.2-efgh.
I don't know exactly when this problem started, but it could have been caused by the recent update from 9.2.1.17 to 9.2.1.21? Is it possible to revert to the previous version? If so, how? Would I lose data/apps?
Type the following in terminal:
ls -l /system/*/su
My guess is that you have two binaries and one or both of them is not superuser with permission rwsr.xr.x
Ensuring CWM working properly, you just try do backup using CWM then, if it worked then it's has nothing to do with being root access problem. And flashing wolf's root zip via CWM is all it takes to regain root after the 9.2.1.21 update.
Mine was similar root access messed after flashing the 9.2.1.21 update. Tried rectified this by copying su from system/bin to system/xbin but still nothing, but my CWM work though and use it to flash wolf's root zip to correct the su missing in the system. Now it work great..

@gee one
ls -l /system/*/su gives me this:
-rw-rw-rw- root root 22364 2008-02-29 02:33 su
-rwsr-sr-x root shell 26324 2008-02-29 03:33 su
So you're on to sth. Top one is located in /system/bin, lower one is in /system/xbin.
Now what do I do with this? Copy one over the other? chmod? chown?
@farsight73
As said in the OP, I tried flashing wolf's root zip in CWM, but got an error and it aborted. I did the following:
put zip on removable sd
reboot to CWM
choose update from zip
select the right zip
confirm
I also tried this with /system mounted, but same result.
I don't have acces to pc now, I will try more tonight.a
[SOLVED]
Thanks for the replies, you got me in the right direction in that I was replacing the wrong su in the wrong way.
Since Brk Toolkit managed to get me an older su, I thought it could as well give me the right one second time.
I replaced the su and superuser.apk in the /adb folder of the Brk rootkit with the one from wolf's root zip, and then used Brk Toolkit to install su and superuser.
Upon reboot, the problem was solved.
Thanks a bunch!
For future reference, I think you could just elevate to the superuser by typing in terminal "/system/xbin/su" Then you could fix system/bin/su with "chmod 06775/system/bin/su"
Then " exit" should drop you to a normal shell, and "su" will promote you in the usual way.
The issue here is that xbin and bin are both in your path, and bin is probably first, so the non-super version is "found" first. "echo $PATH" will reveal your path variable.

HEY MY FRIED I HAVE EXACTLY THE SAME PROBLEM
chmod 06775 /system/bin/su results"unable to chmod /system/bin/su: readonly filesystem "
echo $PATH RESULTS /system/bin/su: /system/Xbin/su
COULD U HELP ME WITH ZIS MY FRIEND

From adb or the terminal, type in "/system/xbin/su" to elevate to the superuser. Then mount system to read-write and delete the /system/bin/su version. Remount system as read only.
This will work if you have two versions of su and one of them is not really super.

So I've rooted my HTC eplorer, installed link2sd etc... now im getting "su binary outdated" and when i try to upgrade it it gives me something like this
Code:
Downloading manifest... okay!
Parsing manifest... okay!
Latest version = 3.1.1
Checking installed version = 2.3.2-efgh
Fixing database... okay!
Unpacking sutools... okay!
Checking current install path... /system/bin/su
Downloading new binary... okay!
Gaining root access... okay!
Remounting /system as rw... okay!
Copying su to /system... fail!
I've googled and tried "SU Update fixer" which gave me signatures OK (I also tried force fixing) and tried BusyBox Installer which when i opened the app and tried installing it gave
"Installing busybox v1.20.2 failed. we have detected that your system cannot function with this version of busybox. Please try installing a different ROM or fixing your system. Error:
reloc_library[1312: 2141 cannot locate 'android_reboot'... CANNOT LINK EXECUTABLE"
Now i have no idea what to do next... any help?
Thanks in advance
p.s. im havent tried any ROM yet

Which Rom u r using?
There z no need to install su/ busybox bcz it already include in custom Roms..
If u want to update Su of ny custom Rom just open google play- my apps n there u ll find update opn..
REMEMBER TO HIT :thumbup:
Where does supersu search for the su binary. I am stuck with the cannot find su manually reroot message. This was after updating a working rooted system to the latest supersu after it asked me to. The only su on the system is in /system/xbin/su there is no su in /system/bin and /system/sbin does not exist.
Can I manually reroot by using adb to create a link from xbin/su to bin/su?
I cannot find any info on "manually rerouting" that says anything but reinstall the latest zip. Which is what I did.
Help!

Hi All.
Sorry about the noob question, I am not a developer at all, and the only reason I rooted my Galaxy Note N7000 was so that I can update the ROM to the newest version of KitKat once the ROM is stable.
The problem is that last week I flashed the PhilZ-cwm6-XXLT4-OXA-4.93.6-signed file to the phone and it rooted successfully (Superclean asked for root access, I allowed it, and it appeared in the log of Superuser)
The problem happened last night when there was an OTA update for superuser, it said Su Binary needs updating, and I hit yes. I then lost root access as per Titanium backup.
I did a search and someone suggested removing and reloading the original superuser APK but that did nothing.
It seems the binary update pooched the root. Anyone successful in getting it back, or knowing how to?
Anyone can help on this?
It appears from the comments in Google Play that many people that were prompted to update the binary from superuser were left without root.
I lost root access on apps once.
All I did was:
1. re-install "superuser" from Google Play.
2. when opening "superuser" app, it asked to update the SU Binary.. and I allowed it to do so through recovery (TWRP/CWM). (I use CWM).
3. the phone will restart into recovery mode automatically, updating the SU Binary, then phone will restart again back into the OS.
This is all it took for myself to gain SU access again.
This should work if the ROM you're using truly does allow SU access.
OTHERWISE.
You could get the latest Super User.zip for your phone, and run it yourself through TWRP/CWM.
Hope this helps, or at least leads you to an answer.
new su binary is the culprit
Hello,
I too lost root after the su update - Superuser would not prompt any more, and all requests are denied after a timeout. Tried deleting Superuser data, deinstalling and reinstalling Superuser, same with some of the apps, but no avail. Then I noticed that sometimes after reboot /system/xbin/su worked when in android debug bridge shell, so I could get root. Then I replaced the su binary with a copy (in my case of OTA rootkeeper), and all started to work again.
Steps to replace:
1. become root in ADB shell using existing su binary
2. remounting system rw
3. bring replacement su to a ext-fs-partition of your device (needed for setuid)
4. make sure file permissions are set to 06755 (-rwsr-sr-x)
5. exit root
6. become root with newly copied su binary
7. replace defect su with new su
8. remount system ro
Hope koush will stop delivering this defect su soon ... I did mail him already ...
