[Q] Why no su access after it's rooted?

I rooted my Nexus 7 a few days ago and was able to replace bootanimation. But now I want to replace my new version of bootanimation using Root Explorer, I found I have no super user access (the terminal prompt does not change from $ to # when I type su at the adb shell). The /system is mounted as r/o. I also have the busybox and supersu zip files on the sdcard. Can anyone please tell me what happen here and help me back to su mode? Thanks in advance!!

I can't see any reason why you'd become unrooted unless you either replace the system partition (via an update or rom change or fastboot flash or whatever) or delete the binary yourself. If you didn't do either of those it could be either a problem with supersu, a problem with the binary, or a problem with your kernel. Try putting the root binary (su) back on the phone and trying again, and if that fails try using SuperUser instead of Supersu. If neither work you may need to do a factory reset and try again.

did you upgrade to 4.1.2? You must have lost root during the process. Just re-root it. I used the toolkit.

oh, yes!!!! I just upgraded a couple of days ago from JRO03D to JZO54K. THANK YOU!!
I tried re-rooting again (w/o flashing custom recovery) after I upgrade Nexus Root Toolkit to v1.5.4 t support 4.1.2, But get stuck at the message "waiting for your device to finish booting back up." Nexus 7 is at the TWRP mode and can't get out of it. So I reboot to bootloader mode and eventually the toolkit tells me to run SuperSU and Busybox. Still doesn't work since I still don't have super user access. What shall I do next? I know there are still few more steps after the TWRP.

please help me in rooting

here , use towelroot to root ur phone : https://towelroot.com/
and if u're on kk use autorec for recovery : http://forum.xda-developers.com/showthread.php?t=2715496
both apks install on ur phone and first use towelroot then install superuser from gplay > open the app and install it's binaries then reboot .
now open autorec and give it superuser access then install recovery .
now you are rooted with recovery(twrp) installed .
if u encounter any issues don't forget to pm me or reply

Replacing KingUser with SuperSU

Hi all, I just want to share this. Regarding to Kinguser cant be replace by SuperSU, I just solve this issue. But, I want to make it clear,
I FOUND THIS METHOD ACCIDENTALLY(by experimenting).
I just got Samsung Galaxy Grand Duos I9082, with home button not functioning. So I cant root it by custom recovery, which made me use Iroot(known as Vroot), 1 click rooting app. It will root using Kinguser binary. Which will give problem to replace it with SuperSU. Then install busybox.
So I reroot my phone using KingO root which will install SuperSU v2.02. I guest this is the point where SuperSU bin get hook in device(I tried installing various ver of SuperSU without success,"Installing Failed". And KingUser give perm to SuperSU using KingO root method.
So I go into SuperSU, install as system, reboot, install custom recovery, install SuperSU.zip thru recovery, reboot, uninstall KingUser(it will warn this will unroot your device back to normal, i just ignore and proceed), and this will erase SuperSU app too, but I guest it leave the binary installed. And again I reinstall SuperSu in normal way, with success.
And again, I'm not telling the best solution, just want to share what I've done. Hope this will help someone.
Good Day

I try to replace King User with the Terminal Emulator Method, and King User gone, but it unroot mi device
I have a Samsung i8200L.
After, I re-root my device (now with Kingo Root, thanks for mention it in your thread), and everything is ok, with SuperSU

Easiest method that worked for me!
Use es file explorer
change permision to /system/bin to rw, tick all
run updated supersu, it will ask to update su binary, use the normal option
Kinguser will ask permission from SuperSu, DENY!
Then you can successfully remove kinguser

I'm assuming you used SSU 2.49? As Chainfire said, he made this mostly for lollipop comparability, also for Kinguser replacements issues.
And thanks for sharing the workaround you've figured.:thumbup:

Hope this will work
Worked on Galaxy S3 NEO ( GT-I9300I ) Android 4.4.4
The Steps that worked for me are as follows:
Start from HERE
1. Same steps untill SuperSu installed
2. When SuperSu launched itself (or you can launch it manually ) , it
will ask to update SU Binary, Click Normal.
3. Wait until SuperSu says other user management app detected (in my
case) and will ask you to remove it. Click cancel ( very important ).
4. When you Click Cancel, it will say Binary updated Successfully. And
will ask you to Reboot or OK. Click OK ( very important ) and not to
Reboot.
5. Now SuperSu will open normally but KingUser app will still be present
( in my case).
6. Now go to Settings in SuperSu App and Go to Clean Up options and
there you will find an option to remove other User Managemnt apps, just
click the option and Boom SuperSu will remove it completely from your
System.
Hope this will work for someone else also.
2nd Method:
Just simply install SuperSu from Play Store and follow the above steps
from Number 2 onwards. (Confirm if it works for you)

AAhh i see. Now i know where you are standing at. you are using magisk. But do you have magisksu ? or keep having supersu as main root but magisk installed? . What i mean to say is, when you go into the magisk app, in the 2nd box of the main screen, does it shows supersu as root method? or magisksu? if it is magisksu then you dont need supersu, now, if it does says supersu, then you do have to fix the issue of supersu to unroot by using supersu function and then go directly into recovery mode and flash magisksu once again.

It says majisksu

then you dont need su (unless you want it). It is because you already have magisksu (which is pretty much doing the same as su). one overrides the other and then one gets thrown out. Usually to install magisk manually, one does as follows:
1) install magisk app from playstore
2) give supersu access (granted to magisk su)
3) use unroot function in supersu
4) flash magisk zip in recovery mode.
Now, there are other methods to achieve magisksu but the point is that maisksu has changed the binary (which is what SuperSU is telling you that you dont have).But that doesnt mean you are not rooted. you are already rooted with magisk and can achieve pretty much anything that you could achieve with supersu. (it will ask you for prompts asking you whether you want to give su access to "x" or "y" app. etc... Now, if you want SuperSU, you could try to flash the magisk uninstaller. Then do the process of rooting that has been specified for your phone. That should return the SU binary to normality . (this assuming you try to unroot and then flash SU back but didnt work)

hey guys bought my ls997 used. has root because i get the flash screen (untrusted)and twrp is installed and working. how do i find out which to flash ? any advantages to use supersu over magisk ?
i installed magisk manager and it states no root found.

Majisk u have to turn root access on majisk works alot better

Did the help @jinkerz9430 gave work for you?

[GUIDE] Change KingoRoot to SuperSU

Follow this ROM Installation Guide.
Root it with KingoRoot.
Flash patched aboot.img by typing "dd if=/sdcard/aboot_patched.img of=/dev/block/mmcblk0p7" command in Android Terminal Emulator App, I don't like to use PC.
Then download ChainFire SuperSU from GooglePlay.
On first application start it will ask to install su Binary, say Yes.
Wait about 5 minutes or until it fails…
If so, don't worry, be happy.
Reboot…
Try again.
It must ask for Root Authorization!
Continue Rebooting and tying again and again, until you see su binary installed successfully!
Now you can dance, you Switched to SuperSU
After that you can remove all KingoRoot sh**t and install SuperSU like System app in application options…
I'm still experimenting with this rom, so I'm keeping KingRoot and SuperSU apps, for reroot my device if I will reflash KDZ.
Since now we have Working TWRP…
Simply flash it via recovery.
There are two ways available : System(by system partition) and Systemless (by Repacking and flashing Modified Kernel Image)…
Google it to know more ?
(1) Download this: https://s3-us-west-2.amazonaws.com/supersu/download/zip/SuperSU-v2.79-201612051815.zip
(2) Place it in /sdcard/
(3) Reboot to TWRP.
(4) Select "Install" and go to the folder where you had placed the SuperSu zip and select the zip.
(5) Swipe to confirm flash.
(6) Reboot to system.
(7) Remove kingoroot's supersu.
