[Tut] (Root) Update to Latest Superuser

Once you have achieved root (see other thread), to update the Superuser.apk to the latest version, run these commands:
Code:
adb shell
su
mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
rm /system/app/Superuser.apk
pm uninstall com.noshufou.android.su
Then search on the market for Superuser and download the one by ChainsDD. Confirmed working on latest Droid2 2.2 ota.
EDIT: To be safe, go to Settings>Applications>Manage Applications and find Superuser. Then clear the data. This should prevent any of the Superuser issues discussed.

sorry..new to the whole android scene. are there any advantages to updating the superuser app the the latest version and can this command be input on the droid itself through the terminal app?

i like the interface much more and its got a new autoaccept after 10 seconds if you arent paying attention when the popup shows. it's up to you. i'm sure future root tools will just include it.

alright thanks. is it as simple as installing the new version and uninstalling the old? or does one need to enter the command prompts listed above?

that is what the commands do. unfortuantely, the old version is on the system partiton. this means that we must first mount the system and read/write and then manually delete the old version ourself. then the new version can be easily downloaded through the market. anyways, adb shell means it's done via your computer so its very easy to copy and paste like 3 commands.

Instructions work perfectly... thanks!

These instructions are not specific to the OS on your computer, they work with anything.

Perfect!
Worked great! Thank you!

Instructions worked fine (I just made them up for Linux), but the newest SuperUser is giving me weird results. Every program that requests root access will ask me numerous times, like it never remembers that I gave the app access. Like removing one app with titanium will it will ask me 4 seperate times to accept or deny permission. Other apps do this also. Anyone have a copy of the old apk I could reinstall? Anyone have any ideas or suggestions?
Thanks

I had the same thing happen to me. Launch the new superuser app and go to settings. Unselect and reselect Notifications. Apparently it shows it being checked, but you have to recheck it for the actual setting to get saved.
After I did this, it only asks once for a program, and then I never see it again.

Nice, thanks!

I had that issue too. I ironically un-installed superuser and re-installed it and it worked fine too

I used Root Explorer to delete the old Superuser.apk from /system/app. Then I rebooted and installed the new version from the market. Worked great.

that works too though without having the superuser apk and rebooting, that could be a little dangerous for others hence my adb tutorial. no need for a restart either. could easily just use root explorer, delete the old, download new from market.

Worked great
I just renamed Superuser.apk to .bak then tried to install. Don't forget the last step. I had to adb (I was using terminal emulator) to do the last step then installed fine and removed Superuser.bak.
Thanks I like the New look.

yeah i can't get superuser from the market to install, keeps telling me unsuccessful

I had the same problem. I rebooted my phone and then it installed fine. Not sure if it's risky to reboot once you remove the apk or not. However, it didn't cause any problems for me.

I basically did the same thing except I renamed instead of deleting it. Well, once I installed SU from the market, I can't find the .apk file even though it's running and launching correctly. I assumed it would be called superuser.apk in the system/app folder but only my old renamed superuser.bak is there. I'm just worried if there is an update in the future, I won't be able to rename since I can't find the .apk file. Anyone know where the .apk file is for this new version of superuser?

Tried this, and it didn't work for me. With Titanium Backup in particular, it will literally ask upwards of twenty times for permission. It's insanely annoying. Any other tips?

[GUIDE]Fix Superuser Permissions!

DISCLAIMER: I am NOT RESPONSIBLE on anything that will happen on your device such as getting bricked or malfunctioning. I only posted this little trick I found out to help others who are also in the same boat. This method MAY or MAY NOT WORK on your device, so proceed at your own risk.
=====================================
Maybe some of you have not seen any Superuser prompt that appears whenever you run apps that needs root (example are Link2SD, Titanium Backup) and etc. Out of frustration last night, I tried to find a way to fix this and I have indeed found it.
But before that here are some of the prerequisites needed:
-Phone/Tablet must be ROOTED
-Has access to system using File Explorers such as Mi(UI) File Explorer, Root Explorer and other explorer that DO NOT prompts Superuser. What I mean here is that you can see /data, /mnt, /etc folders and the like.
..and here are the little steps in fixing it:
1. Download and install BusyBox from Google Play Store.
2. Open BusyBox, select 1.20.2.
3. Click install, and wait for it and it's done.
4. After BusyBox has been installed, download SuperSU from Play Store.
5. Install and let it load.
6. After loading, press YES when asked to update SU Binary.
7. When it's done, press back and try apps that needs root like Titanium Backup.
And there, notification prompt would appear again!
NOTE: UNINSTALL, take note UNINSTALL previous Superuser app through Root Uninstaller. Main reason why that should be uninstalled so that there would be no conflicts with the SU app.
OPTIONAL: you MAY UNINSTALL BusyBox app but I recommend not so to avoid any problems.
I have also applied this method to my tablet that's already rooted but doesn't have Superuser app yet. A simple press of thanks is highly appreciated. :3

hey, I've been trying and trying again but still can't... what should I do? root explorer cant fix my problem.. superSU, superuser fixer, it can't fix my problem too.

but when i try to remove some boltware via system app remover a security pop-op appear and say you can't do it !!!!
what is that ?!
i also tried to remove by link-2-sd , but failed again !
please help

Did you try using titanium backup?

Assuming you have ADB set up, open up the Terminal if you're in Linux or the Command Line if you're in Windows and type the following:
adb shell
su
mount -o rw,remount /system
cd /system/app
ls
rm *name of app*

thank u
i installed terminal on my phone and your command is work!
but u know , by link2sd or "system app remover " you can find out the app by its icon .
so why i can't remove app by application !
- titanium backup , every time i try to trmove an application by titanium backup , it getting freeze! and force close ( after a while )
- link2sd : when i try to remove an app it says can't mount ...
- system app remover : when i try to remove , a security notification appear ...
so how can i remove an app easily by this applications ?
thank u

Maybe you have to try another root method??
Mine is working without any issue

Seems like those apps you want to use do not have SU permission. Did you install SU and Busybox?

It could sound silly but did you check with root checker that you really have root access?
If yes, another reason that I could think of is you might not grant the SU access when you opening up the TB

the point the makes me wondering is that " root checker" says that you have root permission !!!!!!!!!!!!
just one app worked for me !! " root app delete " 6.9.24 !
but this one not working complietely too . when i try to remove a system app it can't install that , but after that , an option appera and ask me : do you want to force uninstall , i said: yes . then uninstalled !
but i don't know why i can't remove the system app like others !
is that related to any security update ?

why my post putting double !!!!!

i moved system apps by root explorer

As I've said, try rooting your phone by another method. Mine without any problem.

You did not respond or confirm to dabgoo that you have super user and Busybox installed.
Did you install Super user PRO, you need to activate it?
I did not active it a first.
You can get a false positive from root checker. It will say you have root when super user is not installed properly. This happened to me.
Check in the Super user app if Super user is actually granting access to other apps.

Could be a long shot, look under settings /general /security /device administrators and uncheck knox if its checked.
I ran into this prob when trying to remove knox. it could apply to other apps maybe. Dunno, worth a try though.

Remove Supersu.apk but keek root

In our project we "lock down" the device and let only our homescreen app running.
therefore we remove all unnecessary apps, and wondering if we can remove superuser or supersu.apk
of course we need root rights, but we dont need the controlling app
we have tested it on many devices, there are a lot where we could remove supersu.akp and our app kept the root right, but on many other devices we lost the root when we removed it
is there anything we have to handle before we remove it, or how does it work?
thanks,

@oisiss, root is dependent on whether or not there are the su binaries existent in /system/bin (among other things). SuperSU is just a root management app, and its being installed does not affect the root access in the device.

Hello, thank you for your reply, but i have to disagree:
1., to check whether the device is rooted or not is not as simple to check if the su binary exists in the /system/bin folder. even if that exists it can happen that our app (and of course many others: rootchecker, es file explorer...) doesnt get admin rights
2., if it would be so simple the root checker app in the google play wouldnt have 10M-50M downloads
3., in our app we also check if the device is rooted, for that we check 5-6 methods: if the su exists, remounting rw the system foder, run su command, create and delete file in a secured folder...
4., many threads talking about how to replace supersu with superuser. all is telling to install superuser first and only after remove the original supersu, so they never mention to remove supersu firts
we have in our lab aprx 60 devices, made many tests, and this is my question:
1., when there is a properly rooted rom, checked by rootchecker.apk
2., we delete supersu.apk from the system/bin and restart the device
3., we check with rootchecker.akk again and says unrooted
so is there any hidden settings somewhere where for example there are default setting for granting or denying root request? or why do we loose the admin righs

I think there is an aswer:
if the original root was not complete (http://su.chainfire.eu/), it can cause issues
the Install-recovery.sh has to be corrected before deleting the supersu.apk (su, daemonsu...)
can someone confirm this?

Has anyone have problem with the recently updated SuperUS 2.65 on rooted Z3?

After updated, many applications seem to lose root privilege.
For example, FX File Explorer cannot browse into several folders; they will be shown as empty folders.
When I reverted back to version 2.46, everything works right again.

I had a similar problem when I installed Super SU 2.65, the root explorer could not browse into internal memory folders and could not write there, also the Titanium backup could not write on the internal storage, so I did some experiments and found the solution : go to super SU settings and uncheck the 'Mount namespace separation', then reboot the phone and problem is gone.
Click thanks if you found this helpful.

I had never thought of unchecking that option because it was checked in version 2.46.
