[Q] su permission denied

Hello there,
I just flashed a new ROM (Gingerbread 2.3.7) last night. After signing in the Google account everything is great; the old apps got redownloaded and all. I noticed that there is no apps listed in the superuser. I tried 'su' command in the emulator terminal & I got permission denied.
Luckily all the apps are working in perfect harmony. However, how do I get the superuser permission back? It seems like my device is not rooted. Do I need to root my phone again? Fingers crossed I don't.
Initially, I tried to flash the Ice Cream Sandwich. I tried multiple times but to no avail. I even tried to change the HBOOT (from CM7 > downgrader > Stock HBOOT) but the process failed. I afraid that this might be the cause my root access got lost. Anyone can verify this?
Thanks!

Su app will be built into the ROM so you should still rooted. Sounds like Su settings are just defaulting to deny. Open Su, menu > settings and check its set at prompt (safer than allow). After flashing new Rom you'll need to launch apps that require root access to allow them permission again. You might need to update the Su app or binaries if permissions don't stick.

beachcomber,
1. my Superuser is set at prompt.
2. I am not sure which app that require root access. Could you give me some examples so that I can run them?
3. I tried to update the su binaries, but I got this:
" checking current install path...FAIL!"
" failed to find currently installed su binary. Update cannot continue."
Therefore, what do you suggest?
Thanks.

Take a backup. Download this. Flash it through recovery. Reboot and check if it works.

Lost shell root access

Hi,
i have a rooted Desire Z currently running CM9 RC2, and I've noticed recently that my # shell has been replaced by a [email protected]:/ and it seems like I don't have root access there. I can't ls in /data/ for example, and su throws a permission denied error. However, apps that require root access(such as Titanium Backup) still seem to work. I noticed this happen right after I installed and ran Busybox. I did not even install busybox from the app as I already have it. I was just trying to get the apk file for another device with no internet access. I'm not sure if this app is what caused it, but it was when I noticed it.
In any case, short of a nandroid restore how do I get back shell root access and the proper shell?
Thanks.

Most likely your root access under System Settings -> Development was changed from "ADB and Apps" to "Apps Only".
PS: why would you be installing busybox, CM9 came with it (likewise with superuser and su).

Thanks. That worked.
Like I mentioned in my original post

Though your quote here conflicted so wasn't sure :

Sorry for the confusion, by running busybox I meant simply launching the Busybox app(which is just an installer, not busybox itself), but not clicking the "install busybox" button in the app to actually install busybox on my phone.

[Q]How To Gain Superuser Permissions Without SuperSU Manager?

Hi XDA,
I am fairly new at the flashing community and I need a quick guide on how to grant Superuser permissions without having to install SuperSU or Superuser managing application. I do not need the application manager to grant which applications gains permissions. I just need all applications to gain Superuser access rights all the time on my devices. I'm aware that my devices will be at security risk and vulnerable and maybe I should just hide the Superuser managing application and allow applications to gain access all the time, but I would like to know which files to flash to allow Superuser access. I do not need SuperSU or Superuser managing applications on my devices if I am going to allow all apps to gain Superuser access at all times. I know this might upset people but I would just like to learn it.
Sample Device Usage:
Nexus 7 (2013) Android Lollipop 5.0.2
Using WugFresh Root Toolkit to automate flash and root but I need it to root without installing SuperSU or Superuser Manager.
(Please excuse me if I used the wrong terminologies and caused confusion!)
Thanks!

You're drunk, go home.

That's not how it works. You're not on Windows anymore.

Just hide the app and be done.

What you are asking can probably be done, but it will never be done, because of the security risks.

You can set SuperSU to grant without a pop-up.

EFS Backup

I need to make an EFS backup, never have before and flashed tonnes of roms, lol. But after reading it's probably a good idea.
Currently on CM13.
However, I've run into an issue. I downloaded Terminal Emulator. I enter "su" and it says on a new line: 255|[email protected]:/
So I then tried to enter: dd if=/dev/block/sdf1 of=/sdcard/modemst1.bin bs=512 - and it says permission denied?
Any help? :]

Root access
Are you sure the terminal has root access?
I use a CM13 variant as well and I had to disable and reenable root access from the developer options before any apps were able to get root. After doing that the first time its worked ever since. Even on cm13 you should get a permission prompt when an app requests root.

Uh, 'su' is apparently supposed to give the terminal root access, apparently? lol
Sorta new to this.

When running the terminal app for the first time, entering su does not instantly grant it root access, but instead makes the app request access. If it has never been given you will get a prompt over the screen asking if you want to give the app root access. If you are not getting this prompt, then do this:
Go to developer options in settings
Tap on root access
Set it to disabled
Tap again and select Apps (or apps and adb)
Then run the terminal again and enter su

Thannks, where are these files once I did this?
It says internal storage but I don't see them.
edit: I see them on my phone but not on my PC when I plug my phone in, weird, lol.

It should come to /storage/emulated/0
Aka the main internal storage folder which includes things like the downloads and pictures folders. The file should be called modemst1.bin
Hope this helps
Edit: I have no idea why it doesn't show when you plug in your phone. Maybe the file is set to be hidden and you dont have show hidden files and folders enabled on your pc? In any case I just backed mine to my google drive

I found them on my phone, not my pc.
They were 2mb each and I emailed them to myself and uploaded them to my dropbox, so all good? I can delete them now from my phone?

Yep, the terminal only made a copy of the files, so as long as you can get them back when you need them they're safe to delete

Give an app su permissions?

I installed the su addon from Lineage extras.
Root Permissions are set to 'Apps & ADB'
"Manage root accesses" is greyed out.
How can I assign root permission to AFWall?

If something needs root access it will ask you. It is not something you can give to an app before it is needed. Once you have granted permission to one or more apps the "Manage root access" will no longer be greyed out.

I uninstalled AFWall & reinstalled, it never asked for root. When I launch it, it gives me the "Make sure it has su permissions" notice. Is there any way to trigger it?
Not sure if its related, but when I go to AFWall Preferences -> Log -> Turn on log service:
"Unable to start log service.LogTarget is not empty or LogService not enabled."

I'm not familiar with AFWall, sorry. Launching it should have triggered the request to grant su perms, at least to my mind it should have.

Late reply but I just had this problem, so in case it could help someone else : I made a mistake to install the addonsu in its last version, on my Lineage 14.1. Big mistake... everything seemed to be ok, except this unability to give root permissions to app (they weren't asking me for at all) and this "greyed out" symptom described here.
I just uninstalled this addonsu to reflash it with the 14.1 version corresponding to my Lineage and... here we goooo....
