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. I have been searching all over the place, and there were solutions, but my phone will not listen to me.
Instructions
1)Download and extract the file below
2)Use a terminal emulator or ADB shell and type.. (or you can use Root Explorer or SGSTools to mount system RW)
Code:
mount -o rw,remount /dev/block/stl9 /system
3)Use a file manager like Root Explorer and copy the recovery file to /system/bin and replace the one there
4)Now, reboot and you should have a modded 3e recovery with no signature verification

On the 2nd part, it will not allow me to mount -o rw,remount /dev/block/stl9 /system.
The terminal emulator is not receiving the "superuser permission", since it's not even asking for the superuser permission.
I did not deny the app nor ignore. I tried reinstalling the terminal emulator, same thing happens.
Also I downloaded ROM Manager. It downloaded me the flashclockworkmod recovery, but it will not reboot into that. Instead it shows the regular recovery mode, and when I try to install the update.zip manually, the error shows again despite the fact that I did all the parts except the 2nd step, because my terminal emulator kept getting denied access when I entered that in.
Please help me. I don't know what hard life my phone is going through.
Asked and answered many times. You could have posted in an existing thread. If your phone is not rooted you will not be able to do this.
My phone is rooted. It has superuser app, along with other apps that require superuser permissions.
How would I have done step 3 without my phone being rooted? if by using root explorer?
I just stated that Terminal Emulator is not receiving the "superuser permission".
I don't know how to manually give Terminal Emulator the "Superuser permission" since, it is not asking me for it, as previously in Eclair.
Are you entering
Su
Sent from my SGH-I897 using XDA Premium App
? I am sorry, I did not understand what you said.
on my Su, I have
Allow
AdFree
ROM Manager
SGS Tools
because they asked for su permission.
But on the terminal emu, it does not even ask for a su permission.
to do unrooted you use adb to push
or root it then use root explorer to drop new 3e fix
try uninstalling terminal em and reinstall. you might have pressed back when it asked the first time, that will screw you
When you mean drop new 3e fix, does that mean to delete file and replace with the updatedone on xda?
I did that previously and rebootseveral times before, but same error came up
Thread closed, already answered.
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..
Sent from my awesome rooted Defy: 2.3.6
@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.

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 ...
Hey everyone,
I'll be showing you the easiest way to replace Kinguser/KingoSuperUser or any other superuser app with SuperSU.
Procedure:
1. Download & Install ES File Explorer
2. In ES File Explorer menu ☰ , scroll down and enable the Root Explorer option
3. Now click on Homepage > Device > System > app
4. Once you're in the system/app folder, look for Kinguser.apk or KingoSuperUser.apk or any other Superuser apk that you have.
5. Delete that Superuser.apk, and go to Playstore and install that same Superuser app. Once installed, uninstall it from Playstore.
6. Now download and install SuperSU and update binaries via normal mode.
7. After 2 to 5 minutes, your binary will be updated, SuperSU will be installed correctly and now reboot your phone.
Note: Do not worry, deleting the SuperUser .apk will not unroot your phone. And this is also a fix for binary update issue.

I don't understand that step. I rooted with KingRoot but this App isn't on playstore.
So I deleted the .apk, installed new from my downloaded apk and uninstalled with Titanium Backup.
The SuperSU still complains that it cannot replace the su-binary.
Any idea?
My phone is a Honor 4X Che2-L11 with an ARM Cortex-A53 Processor.

I followed the manual steps that Supersu says when installing the app (redirects to a web). It says there are 2 options, the other is installing Supersu-Me, but I haven't tried that (there seems to be issues for Lollipop). Also, in my device there was only one Kingo Superuser app and a Kingo Link app (I have seen webs where Kingo installs up to 3 things).
You need root (Kingo), su binary file, busybox, terminal emulator, ES explorer, supersu app.
Step 1: Install ES explorer with root.
Step 2: Rename Su to .SU
Step 3: Copy .SU to system/xbin
Step 4: Authorize .Su. For that, open terminal and type:
system/bin/su
mount -o rw,remount -t rootfs rootfs /system
chmod 777 /system/xbin/.su
Step 5: delete the other SU files, such as ksu, etc.
# check attributes
busybox lsattr /system/xbin/su
# remove a and i
busybox chattr -a /system/xbin/su
busybox chattr -i /system/xbin/su
# remove su
rm /system/xbin/su
Step 6: Rename.SU to SU
Step 7: Go back to the desktop to delete the other authorization apps, uninstall KingoRoot,
open SuperSU, it should ask to update binaries, choose yes, choose NORMAL, and reboot.
Hope it helps!
where is file ,
pzl upload the su file here,
and ur procedure is not understanding
properly ,
plz give procedure how to do this ,
or upload video,
@tosho1 its because huawei protect system partition on locked bootloader devices.
reflash stock rom, root with kingroot, flash twrp with rashr, unroot inside of kingroot and flash supersu with twrp
(you will be able to unroot because system is still mounted after rooting but after reboot you wont be able to touch it, thats why you have to use kingroot only to flash twrp and then remove it when you are still able to)
(method tested and working on my own che2-l11)
Thanks for your reply MarcoPLs.
Meanwhile I managed to get root working flawlessly. Don't ask me, how It's too long ago.

What worked for me was finding older version of kingroot app and rooting with that then using super SU me.apk

Replace Kingroot With SuperSU
Hello everyone.
I have been wanting to get to grips with linux for a while now and decided linux decided to try completelinuxinstaller as i was having some problems with linux deploy.
i set up everything as the app asked. Downloaded .img files, extract, rename file and launch.. but in the android terminal i get a error which said:
chroot: can't execute '/root/init.sh': Permission denied
After days of searching and trying minor fixes i got no where until i found a list of instructions on how to fix this error.
(This error is becoming common on Samsung devices running android version 4.4.2, and can be expected to happen with some other devices, or newer versions of android. Although I haven't yet found the exact cause of the error, an effective workaround has been found:
The error seems to be coming from something in the busybox executable installed by the Complete Linux Installer app; many have reported that using other versions of busybox removed this problem, and the following version (free download on Google Play) has been confirmed to work: BusyBox
After using that app to install an updated busybox binary, simply copy the new binary over the existing busybox binary at /data/data/com.zpwebsites.linuxonandroid/files/busybox
Finally, in a rooted terminal window, type chmod 0755 /data/data/com.zpwebsites.linuxonandroid/files/busybox (see the more detailed instructions in the How do I install the most up-to-date version of bootscript.sh on my device? section of this FAQ)
Now you should be able to start linux using your Complete Linux Installer app on your device.)
But the problem is no matter what explorer i use i am not able to find the busybox config file. Where they said it would be doesnt exist. Even if i go to android/data its not there. Just the .com for all other apps. do you know where the busybox might be ?. On the busybox installer it says it is in /system/xbin but again i cant find it on my device.
And if i may chew your ear off for one more moment. How can i change the .config file ?
Thank you for your time
