When updating the su binary, the su in /system/xbin is corrupted, so I can't gain root access. Any ideas how to get it back?
EDIT: Apparently this is a known issue:
http://androidsu.com/2011/10/i-updated-to-3-0-1-binary-and-lost-root-help/
DO NOT UPDATE THE SU BINARY TO 3.0.1!
Here's how to fix it temporarily:
1. Download this file: http://goo-inside.me/superuser/su-3.0-bin-efgh-signed.zip
2. Copy it to the root of your SD card.
3. Reboot to recovery.
4. Install that zip file.
EDIT #2: The latest binary 3.0.3 works fine. It should be safe again to update your version of su.
I'm currently running on yakju 4.1.1 and I think I've accidently messed up my root privileges. I think I somehow messed up my su by clicking the root button in Nexus Root Toolkit 1.5.
Cause:
I've always used Voodoo OTA Rootkeeper to keep my root. I update the SuperUser app via the market and found out that my su binary was out of date. I've tried various ways to update the su binary but gaining root access always resulted in a failure within the SuperUser app so finally I decided to try out the root toolkit. By clicking the root button in the app I think I've only made my situation worse....
Now I'm seeing that my su backup in the Rootkeeper app is messed up and I can't seem to delete it. The RootKeeper app seems to think that I'm still rooted and I can't successfully do the "temp-unroot" as well. Other apps such as Titanium Backup can't detect my root status now....
Can anyone offer any suggestions without re-flashing my image?

As of Nexus Root Toolkit 1.5.2, I do not see yakju 4.1.1 in the list of supported devices.

I've figured out the solution to my problem: just re-push su & Superuser.apk to /system/su and /system/apps/Superuser.apk respectively.
Basically I referenced this thread: http://forum.xda-developers.com/showthread.php?t=1531865
Since I already have su and Superuser.apk in my /system (although I think I tainted both files), all I needed to do was grab clean versions of su and Superuser.apk and adb push em through and type "adb shell su" to make the # appear. I was even able to update su binary within Superuser, awesome :good:
Note: Once you do step 6, your prompt should change from $ to #. If not, it did not work.
7) Mount the system partition as rw: mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
8) Copy su to /system: cat /data/local/tmp/su > /system/bin/su
9) Change permissions on su: chmod 06755 /system/bin/su
10) Copy Superuser.apk: cat /data/local/tmp/Superuser.apk > /system/app/Superuser.apk
11) Change permissions on Superuser.apk: chmod 0644 /system/app/Superuser.apk
12) Mount the system partition as r/o: mount -o remount,ro -t ext4 /dev/block/mmcblk0p1 /system
13) Rescind root: exit
14) Exit the ADB shell: exit

Hope this helps with people who are having troubles with Superuser/su not gaining root access.
If you have an unlocked bootloader and the SU binary is still on the phone, this should fix the issue:
http://forum.xda-developers.com/showthread.php?t=1765754
As for the superuser APK, it does NOT need to be moved to the system folder, it just needs to be downloaded from the marketplace and will function if the su binary is present with proper permissions.

I guess it makes sense, the only real issue was my su permissions.
I did this with a locked bootloader btw.

So once I was done rooting my phone and turned it on for the 1st time I instantly was greeted with superuser has stopped and security violations. So I tried random fixes from google and it keepa teling me there is no binary code. I can't figure out how to fix this, can anyone help me?

I can't find it anymore. It was on this forum and it said it was for att S3 phones. Is there an area where all the ways to root are?
This is what root checker pro gave me as the results.

Try Chainfire's CF autoroot with SuperSU, including google play SSU update to App? It sounds like you failed to reboot into recovery first before doing a normal boot. After flashing via odin, the root is temporary and will be wiped during a normal boot, unless you first reboot into recovery. So, you have to uncheck the reboot after flash option in odin. After successful flash, pull usb cable and boot into recovery using three button method.
Did you use CF autoroot? Try it again.

I did reboot into recovery. I remeber the files I downloaded were named clockword mod and another was called superboot with cwm. Don't k ow if that helps.
I'm having a big issue though, I had tried fixing it by flashing dif ways, now whe I try tk flash it. When it loads up in download mode, my phone turns off or of ot doesn't do that, after I flash my phone and it reboots, it shows a red screen.
EDIT:
I just tried that root method you suggested and I still have the same issues. I don't know what to do!
EDIT 2:
I fixed it by using this site http://www.w0lfdroid.com/2013/12/Fix-Root-Problem-on-Android-4.3-for-Galaxy-S3-S4-Note2-Note3.html. Specifically, these instructions:
Download and install the latest APK for SuperSU like MrW0lf suggested.
I was having the same exact problem (unfortunately, SuperSU has stopped), so I downloaded the latest UPDATE-SuperSU file and extract it to have supersu APK, put it on my SD card in my phone and installed it from there.
It was strange because the version that was already on my phone was the same 1.89 version that I downloaded, but regardless, when I clicked on the APK, it saw it as an update, it asked to disabled knox, and worked like a charm.
- See more at: http://www.w0lfdroid.com/2013/12/Fi...y-S3-S4-Note2-Note3.html#sthash.0nlj3XHO.dpuf
PS: this is the root method I had 1st followed, http://forum.xda-developers.com/showthread.php?t=1726960
I used hide my root to hide mu root and when I hid my su binary and tride to restore it will not restore at all. Is there any way I can restore it without factory reset. I still have root as xbmc launcher works perfect.I am on latest build and used custom rom via clockworkmod.
Any body that can help me with this please

I am using supersu pro by chainfire and need to install binary for it and wondered if any one can upload a zip of it please.
Here you go....
I also lost su binary using Hide my root app, can you please check if I am going to perform the correct steps to recover it:
download su apk from the post above
reboot in recovery mode: adb reboot recovery
push SuperSU_v2.01.apk to /system/app: adb push SuperSU_v2.01.apk /system/app
reboot
Thanks a lot,

After dabbling around in some murky waters trying to achieve root, and going trough some 2010 stuff I did, I did discover a method I devised back then works to some extent, strangely.
Using fastboot (boot) to a TWRP recovery image (TWRP_v2.8.6.0_honami-f2fs_from_cm12.1_150423.img), mounting /system, and pushing a version of busybox, bash and using the supersu su binary already in the TWRP recovery image.
boot-new.img.bz2.zip (rename to boot-new.img.bz2 before extracting -.Just TWRP_v2.8.6.0_honami, with a different kernel and dt image included to boot from fastboot)
bash and busybox i compiled from git and debian sources yesterday/today
Basically this; (use only for reference.)
Code:
# Magically push all files in place here.
# Optionally, move /system/bin/sh out of the way and link /system/bin/sh to bash
./"$ADB" shell "chmod 755 /system/bin/bash && chown 0.0 /system/bin/bash"
./"$ADB" shell "chmod 4755 /system/bin/busybox && chown 0.0 /system/bin/busybox"
# TWRP
#./"$ADB" shell "cp /supersu/su /system/bin/_su"
./"$ADB" shell "cp /supersu/su /system/bin/su"
./"$ADB" shell "cp /supersu/supolicy /supersu/su /system/xbin"
./"$ADB" shell "cp /supersu/libsupol.so /system/lib/"
./"$ADB" shell "chmod 0644 /system/lib/libsupol.so && chown 0.0 /system/lib/libsupol.so"
./"$ADB" shell "cp -r /supersu /system/app/SuperSU"
./"$ADB" shell "chmod 0755 /system/app/SuperSU && chown 0.0 /system/app/SuperSU && chmod 0644 /system/app/SuperSU/SuperSU.apk"
#
#./"$ADB" shell "chmod 4755 /system/bin/_su && chown 0.0 /system/bin/_su"
#./"$ADB" shell "echo "busybox su -c "_su"" > /system/bin/su" # or busybox su -c "_su -c /system/bin/sh-org"
./"$ADB" shell "chmod 4755 /system/bin/su /system/xbin/su* && chown 0.0 /system/bin/su system/xbin/su*"
# Quite dangerous - Suggest moving passwd when in normal use
./"$ADB" shell "echo "root::0:0:0:/root:/system/bin/sh" > /system/etc/passwd"
./"$ADB" shell "chmod 0644 /system/etc/passwd"
Next step, to remount /system with write permissions from a normal boot, I think, would be to modify boot.img/default.prop and set "ro.secure=0"
Thought I had done this prior, I run with touch disabled as I cracked my screen (impressively massive drop of at least 30 cm! - onto object.. ) ... I could not remount system when I first tried.
Notes:
If i adb in early i can use supersu/su to gain root, when system is loaded busybox su -c ""supersu/"su" works. - NO AUTH
Hm, updated SuperSU via google play and suddenly it realized it was rooted . = ) Still keeping the supersu/su intact in /system/*bin
Thankfully I've been unsuccessful in grabbing root from /data/local/tmp this way as of now. Seems the permissions are reset. Though getting root without any auth is a serious matter no matter how you flip the coin. At least it's not as easy as pushing an archive to /data/local/tmp and running busybox su -c su. Also with a modified busybox you could easily skip the part where I write a /etc/passwd with no password.. Incredibly handy if you need root without Android running, say with setprop ctl.stop zygote, media and bootanim. But incredibly dangerous!
Fastboot to attached TWRP and install [STABLE][2016.02.02] SuperSU v2.65 - http://forum.xda-developers.com/showthread.php?t=1538053 - drop the zip to somewhere on the device and use the install function, i installed supersu via google play first. Attached is the kernel image i'm using. On a side-note, the script above failed .
Apart from this, the attached gnu-tools i will have to update... Got a neon flags optimized for out cpu and all, but that's for a different day.
Cheers, have a good one mates
Noob question: what is the difference between using this method for root and kingroot method? Which is better to use?
I've not checked Kingroot. But my thought is not to rely on nasty kernel exploits and have an as clean as possible root. Kingroot was not working when i first started this post. Also i dont leave system read write mountable. To do system modification i fastboot the TWRP image

Kingroot give you root but not supported and their binary are weired but when you replace it with supersu you can't mount system read/write cause of ric but thanks to Chainfire and his tools I find way to root with kingroot and replace it by supersu and disable ric
Noticed my boot img was rebooting sometimes, went off and updated my compiler toolchain and had a look at the kernel and recent developments.
Had a look at X-Honami v6 and ported some parts of that effort to the latter Sony kernel used in 14.6.a.1.216.
* Messed around with memutils and implemented ARM_PLD_64BYTE and USE_LDRDSTRD_OVER_LDMSTM atop memutils from the Xperia-dev unified kernel. - this needs some testing but appears to be stable at least with the options turned on.
* Slight overclock of GPU to 533 mhz, and underclock to 27 mhz on idle.
* Has kexec hardboot
I cannot busybox su -c su with this kernel. Which is only useful for developers anyway. You'd be wise in running some benchmarks before and after the flash.
Kernel needs to be flashed via fastboot.
