What is the correct way to add the SuperUser app?

Alright so I installed Haykuro's Hero rom the other night. I noticed su worked fine in terminal emulator, but I couldn't tether cause root apps weren't working. Figured I would try adding the Superuser.apk so that apps requiring root would work for me. I couldn't locate instructions on how to go about doing so and had to wing it a bit.
This is what I tried and it seemed to work...kinda.
Extracted su binary and SuperUser.apk from another build (Haykuro's 6.0r1)
adb push su /system/bin
adb push SuperUser.apk /system/app
All the apps that require root are working, but the SuperUser app is not asking for confirmation on new permissions request. So if I am correct in my assumption, su privileges are being granted to any app that makes a request for them.
If someone would care to elaborate on how this is properly done, I would greatly appreciate it.

If I remember correctly from when Haykuro release the Ion this is all that he said to do. i have done this also and it concerns me as the SuperUser app is give you the option to allow access and it is not working. No safe guard for the phone.
Below code is assuming you have already taken/have the su app from another build it can be found in the system/bin.
Code:
adb remount
adb push su /system/bin
adb push su /system/xbin
adb shell chmod 4775 /system/xbin/su
adb shell chmod 4775 /system/bin/su
You may also have to clear all data in the SuperUser.apk if you already have it installed. Do this by going to settings> applications> manage applications > Superuser permissions > clear data. But now my phone is asking for superuser permissions. I found this in another Thread but this is a windows.exe file the above codes would work for those who dont use windows and can't run the .exe file that you download there like myself.

Rooting and su permissions

Assuming I root my Nexus S and install su.
Does any application that wish to use it can just use it or there's some kind of popup that asks me for password or at least confirmation ?
If not sound like a too big of a risk to root

The superuser app will give you a pop-up and ask for permission. You can set some apps to always have permission, and you can revoke whenever you want through the superuser app. The app is in addition to the binary that actually gives su rights.
Superuser asks permission even for adb from the terminal, so I think it's pretty good protection.
You also get a notification bar or toast message every time an app gets granted su rights.
I don't feel unsafe on my rooted phone.

All right, sounds decent.
Thank you.

As I observe in my unrooted Nexus S, su comes pre-installed in Nexus S. Unlike Samsung captivate (unrooted) where, if you run su on adb shell, you get 'command not found', in the Nexus S, I received the message 'Permission denied'

Su is not pre installed in the nexus s. If it where then it would be no need to install it as part of the root process.

[email protected] is your phone an out of the box new purchase? If you really do have su installed already, you might have gotten someone's returned unit.

[Q] How to tell if rooted correctly?

I followed the BurritoRoot method on my KF 6.2.1. I have installed the marketplace, a new launcher, and lots of other apps.
All I wanted to do was change the permission to stop the wallpaper rotation. However when i browse with ES File Explorer, I get "empty folder" if I look in /data. So I attempted to open the setting of ES File Explorer and select "Root Explorer". and it told me Sorry test failed unable to run this feature on your phone.
Finally I downloaded a program called "Root Check" and clicked Verify Root Access, its gives me "Sorry, you don't have root access."
However the fact I can install all these apps, etc leads me to believe I do have access.
One last this. I have a Nexus S 4g root, and it often prompts me to to use superuser app, I am not seeing this on the KF.
I do have GO Task manager widget, that shows the superuser icon as loaded.
I am very confused. In the end all I wanted was to stop the blasted wallpaper changer. HA!
ty!

If you used BurritoRoot and you were able to successfully install the Market, then you likely have root.
Easiest and simplest way to 100% know is connect your KF to your PC. Run the following:
Code:
adb shell
su
If it says "su: Permission Denied" you don't have root (or at least it is not currently enabled). If it just gives you a prompt run:
Code:
id
If it comes back and says "uid=0(root) gid=0(root)" then you are good.

Make sure you use the superuser posted in the burritoroot post. There was one posted originally that was no good with the kindle fire but they updated to a working one.

if you want to know your kindle is rooted, use root checker, installed it on you KF and check.

I tried that app and it reports, "Sorry, you don't have root access."

Looks like I have some more work to do, and I am not sure where to start.

Ok I went back and re-ran everything. Had to uninstall SuperUser in the middle, but things seem to be working better now!!!

how to allow root for apps?

I have a nvidia shield tv with full android 6.
adb root and and adb remount is working, so I have root access on shell level.
Also I have /system/xbin/su which goes into root if I do not use "adb root".
But root for apps does not work. No app gets root access, RootChecker says "no".
I installed Superuser.apk but this did not help.
What is missing?
I see that this:
java.io.IOException: Error running exec(). Command: [su] Working Directory: null Environment: null
Caused by: java.io.IOException: Permission denied
I saw that RootChecker tells me "SELinux enforcing", is this the problem?
I do not want to download any ready-made root miracle and flash the whole device.
Since I have adb root, I can adb push everything.

Just flash su.zip and all will be fine.

I don't need SuperSU. I want to root my device i.e. that apps can execute su.
I have /system/xbin/su but it seems that apps cannot use it.

SuperSU is required to give root access to apps, even with full Android. You will need to flash the zip file from TWRP recovery.

How does SuperSU work?
As far as I understand, there is a /system/xbin/su which is called by apps wanting root access.
This su binary then starts the app to verify access. Right?

Not sure, but I think that su is just for adb and maybe system apps.

On my system I have "adb root" access. But apps do not have root access, I do not have supersu or su.

How can I install SuperSu on a pre-rooted Android head unit?

Hello everyone,
I am working on a pre-rooted Android head unit. I can do "adb root" or "adb shell su" using wifi adb. So there is root access and Su binary on the device. But I can't use root applications because there is no app to grant root access. I have tried installing supersu or superuser on /system/app. I made it install the apps but they say "device not rooted" when I try to run them.
So how can I make supersu see my su binary?
