ryude said:
You need to use adb to go in the file system and delete all trace of superuser and busybox. That is the only things rooting does, places those files on your phone and changes file permissions. File permissions, they won't look for, but I've had best buy scroll through the app drawer on multiple occasions looking for superuser/rom manager.
I have attached a zip containing all the files needed for adb. Since they no longer package adb with the sdk. Just open command prompt and cd to the directory containing adb. Make sure your phone has Usb Debugging enabled, then connect your phone.
You might need to download usb drivers in order for windows to recognize the device, but probably not. Once your phone is connected, do the following.
Code:
adb devices
adb shell
su
rm /system/app/Superuser.apk
rm /system/bin/su
rm /system/bin/busybox
rm /system/bin/rootshell
reboot
Click to expand...
Click to collapse
but when i write rm /system/app/Superuser.apk it say
Read-only file system
so what should i do i only get my XS unlock then install superuser using
install-superboot-windows.bat
and i never do recovery!!!!!!
so any help
i need to get my nexus like new and i should then gt updates

You can have superuser and get updates. The update will remove root though. You could always wait for the cm nightly to include 2.3.3
Sent from my Nexus S using XDA App

You have to mount the /system partition as read/write.
Easiest way is use Root Explorer.
You can also try the following from adb or terminal on the phone:
Code:
su
mount -o rw,remount /dev/block/mtdblock3 /system

thanks for your reply
i used Root Explorer to mount the /system partition as read/write.
and then
i did write this codes
adb devices
adb shell
su
rm /system/app/Superuser.apk
and every thing was ok
but i have an error on those lines
rm /system/bin/su
rm /system/bin/busybox
rm /system/bin/rootshell
and every time i get file not found
so what i should do???

hello, tominater12 and thank you for reply
cold you tell me how i can remove superuser and root using the update??????
i want to get my nexus s like new no root no superuser
so any one can help?

hi guys,
this is my first post in the forums, but after reading and watching many videos on how to remove it i have found a solution...my nexus s is now unrooted with no superuser...
make sure u have android sdk installed, and have usb debugging on.
restart phone into recovery
open cmd and type -
cd c:/AndroidSDK/tools/
adb shell mount /system
adb shell rm /system/app/Superuser.apk

[Q] ATT Avail root

I been looking for an ATT Avail root guide since january, I found this page today and I am wondering if anyone has done this successfully?
if you google "root att avail" it is the top search result link right now and it is at a site called android police.
here is a copy/paste of the article:
New root methods show up all the time, so it's not a huge deal that a rather unknown phone on AT&T is now rooted. So why are we posting about it? Because the root method used is, well... interesting.
It was uncovered by our own Justin Case from TeamAndIRC, and while a big part of the process will look very familiar to some of you, there is one step that induces a wait, what? moment.
Before you get started throwing commands at the little guy, though, you need to grab this file. After that, commence command throwing.
adb shell rm -r /data/local/logs (if this command gives you an error, do not worry, it is precautionary)
adb shell mkdir /data/local/logs
adb shell ln -s /data/local.prop /data/local/logs/loglast1.tar.gz
Dial *983*7668# on your phone. This does a few things, it mounts /system as writable on boot, and creates the loglast1.tar.gz.
Wait about 10 seconds, then continue.
adb shell echo 'ro.kernel.qemu=1' > /data/local.prop (Nod to Rosenberg here)
adb reboot
Once the phone reboots, continue
adb push su /system/xbin/su
adb shell chown 0.0 /system/xbin/su
adb shell chmod 06755 /system/xbin/su
adb shell rm -r /data/local/logs
adb shell rm /data/local.prop
adb shell rm /data/property/persist.sys.ztelog.enable
adb shell rm -r /data/local/rwsystag
Head into the Market and grab the Superuser app.
Done.
Catch that bold part? Looks like someone at ZTE dropped the ball and left seventy-nine developer codes in the retail version of the device. Oops.
Of course, their mistake is your gain. Hell, there's even a code to disable Carrier IQ: *983*24737#. Enter the code, ???, profit.
While this is definitely an unusual and unique find, it's also quite dangerous. This means that any app can mount the system as writable and, from there, basically control everything. As a result, JCase contacted ZTE to let them know of their oversight.

if someone could let me know if this is legit, that would be a fantasticism.

yes that is legit.
see my thread:

Jcase broke it, the loon created a batch file to make it easier
http://forum.xda-developers.com/showpost.php?p=21627136&postcount=37
thats the last version of the batch file

Cool, thanks, for some reason I cannot connect to my avail via usb, I have it in developer mode and unknown sources checked, I ran adb devices command and it does not find my phone and when I try to run or debug in eclipse it does not find my phone there either.

I used it, and now have root. I wish all phones were this easy to root.

Help: Good For Eterprise on a previously rooted phone

Trying to install GFE on a previously rooted but now unrooted phone. It's failing because it thinks I'm still rooted.
I have unrooted, removed Superuser (the apk and from the App list), etc.
What the hell is it finding?

Maybe su or busybox in the xbin folder?

Yes. They are both there. But how do I get rid of them now that I'm not rooted? ADB shell errors out with read only file system. If I re-root and delete them, then how do I make the file system read only again?
Also, do I need to get rid of /system/bin/su or is that part of stock Android?
Thanks so much for any help.

So all you did was delete the .apk? Download Super 1-click, re-root, then use it to unroot.

I rooted by flashing the update.zip and then unrooted by removing the Superuser app and then changing the file system to read only.
I thought SuperOneClick only worked with FroYo on the G2X and not with Gingerbread.

Success!!!!!!!! Many thanks to jboxer and others that pointed me in the right direction.
Here's what you need to do for anyone else facing this issue:
1. Boot into Clockwordmod Recovery and then connect your phone to the computer. CWM Recovery will be seen on ADB with root permissions.
2. Before issuing the following commands, after your phone is connected, use the menu in CWM Recovery to mount the system. If you don't mount the system you are seeing CWM's mini Android system and not the phone's.
3. Issue the following commands from your computer:
#adb uninstall com.noshufou.android.su
#adb shell rm /system/app/Superuser.apk
#adb shell rm /system/bin/su
#adb shell rm /system/xbin/su
#adb shell rm /data/local/tmp/psneuter
#adb shell "find /system/xbin -type l | xargs rm"
#adb shell rm /system/xbin/busybox
4. Use the CWM Recovery menu to unmount system.
5. Reboot your phone.
Before you attempt to re-run the Good setup, check one last time to make sure that su is gone from /system/bin and /system/xbin and that Superuser does not show up either in your Apps or when you go to Settings->Manage Apps. If any of this is still present you need to redo what is written above as the Good setup will fail.
I also recommend doing a Nandroid before unrooting, a second Nandroid after unrooting but before installing Good, and then a third Nandroid immediately after successfully installing Good.

I saw that program but it seemed a little spyware laden. So I decided to try and find another way, and after about 6 hours of messing around succeeded. Glad someone else benefited from it as well.

Oh it is a POS program with ALLOT of spyware. But since i was using on my virtual PC I didn't really care
But yea thanks again !
PS. What have you really done to yours since you rooted it ? I've been slowly removing the bloat-ware.

I want to compile clockwork recovery but that is a lot more work and i risk perma-bricking my phone, but I have been using titanium backup and root explorer. Be careful of what programs you remove, the phone may have root but it still has a locked bootloader that freaks if you remove the wrong app.

So what apps have you removed safely. I've gone and removed the normal ones (Facebook, exchange, etc).

How to access data folder from non-rooted device?

A few weeks ago one of my important apps started crashing on open.
Since I have important informaiton saved on that app I need to obtain it.
Is there a way to access that package folder (and that app is not debuggable) with adb or shell?
When I try to access via adb and shell the result it Permission denied.
I can't root the phone, so this is out of the quesiton.
I'm using Google Pixel 1 with Android 10 Build - Build/QP1A.191005.007.A3)

There isn't any way to access /data/data/ as a normal user or shell user, the only user able to access that is root, at least according to the permissions.

You could try to backup using "adb backup package", then you could apply this backup back on another phone or on this same app after reinstalling it.

Temporarily root phone's Android, means add su cmdlet what is suitable, and then mount the partition in question as RW by means of ADB applying su.
Example:
Code:
adb devices
adb push <SU-BINARY> / data/local/tmp/
adb shell "chmod +x /data/local/tmp/su"
adb shell "/data/local/tmp/su -c 'mount -t auto -o rw,remount <PARTITION-IN-QUESTION>'"
adb pull "<DIRECTORY-TO-PULL>" <LOCATION-ON-PC>
