+after doing that should i get official updates?

and i try this solution
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

How to root the Droid 2

All credit for the binary goes to Sebastian Krahmer at http://c-skills.blogspot.com/. Please see fit to donate via Paypal to [email protected]
If you want a simpler 'one-click' process, go to this thread: Easier 1-2-3 Droid 2 Root for Windows / Linux / Mac
***NOTE: Proceed at your own risk. I and the providers of this code are not responsible for anything you do to your phone!***
Setup:
- Install adb (here) and Motorola drivers for windows(32-bit or 64-bit)
- Download attached archive
- Extract to a directory, I used c:\Droid2Root
- Make sure you have USB degugging enabled
- Change connection to PC Mode
Process:
- Open command prompt
- cd c:/wherever-your-sdk-tools-folder-is
- adb devices (to verify the connection)
- cd c:/Droid2Root
- adb push Superuser.apk /sdcard/Superuser.apk
- adb push su /sdcard/su
- adb push busybox /sdcard/busybox
- adb push rageagainstthecage-arm5.bin /data/local/tmp/rageagainstthecage-arm5.bin
- adb shell
- cd data/local/tmp
- chmod 0755 rageagainstthecage-arm5.bin
- ./rageagainstthecage-arm5.bin
- let the process run until it 'kicks' you out (may take a minute or two) to c:/Droid2Root
- cd c:/wherever-your-sdk-tools-folder-is
- adb kill-server
- adb devices (to verify the connection)
- adb shell (you should now have a # prompt, if not return to ./rage step above)
- mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
- cp /sdcard/Superuser.apk /system/app/Superuser.apk
- cp /sdcard/su /system/bin/su
- cp /sdcard/busybox /system/bin/busybox
- chmod 4755 /system/bin/su
- chmod 4755 /system/bin/busybox
- mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
- exit
- exit
I'm sure there are certain steps that could be streamlined or eliminated, so please feel free to make a suggestion and I'll edit the post.
Additional thanks to @rainabba and AllDroid.org for their excellent Droid X rooting tutorial, which assisted me greatly in this process.

I wouldn't remove anything yet since we don't have a sbf file to recover from partial bricks. However, tethering and any other apps that require root can be used now.
I'm new to doing this all the adb way.
When you say extract to a directory what do you mean to extract. After it downloads the achive files its done.....
i understand the rest of the commands but im lost there
Hmm, alright, that's still worth it, will I lose my data/have to hard reset to root?
Right click the downloaded archive and "extract files". You need to do this so adb can push them to the phone.

Nope, it just gives you access. Nothing deleted.
I'm retarded i didnt realize it was attached to the post, i thought it was what adb downloaded when i first opened it cause it called them archives.
cannot access
I got as far as pushing super user su and busy box onto my phone but it says that system in read only.. how do i fix this?
Anybody actually try this?
Hello,
I am following your directions and when I get to the "adb push Superuser.apk" step I receive the following error:
"failed to copy 'Superuser.apk' to '/system/app/Superuser.apk': Read-only file system"
I get this same error for the other adb push steps that follow.
Edit: To verify, I get a # shell.
Edit 2: I tried pushing the Superuser.apk to /data/local/tmp then cp to /system/app/, this also popped up a read-only file system error.
I'm currently trying it.
I have a 64 bit driver on my computer that i used to use for my D1 but it doesn't recognize my D2 when doing adb devices and i cant install the 32 bit driver

Did you add any steps to mount the system? I don't believe I did, but it seems others are finding it to be read-only.

Don't know if it will help you, but if it's anything like the DInc, you could just use the SDK's drivers and add a few device identifier lines to the INF file before installing them.

ADB question

I have read many posts about ADB push/remount permission issues, etc. But unfortunately I still have not figured out what's wrong with my situation. First of all, I don't have a micro SD card, so I have to push files directly to the phone memory.
I firstly tried "adb push" but seems it doesn't work for me
$ adb push email.apk /system/app
failed to copy 'email.apk' to '/system/app/email.apk': Read-only file system
Click to expand...
Click to collapse
Then I searched online and people said you need to remount first. Then I got the infamous permission problem
$ adb remount
remount failed: Operation not permitted
Click to expand...
Click to collapse
Then I tried open shell first. no go
$ adb shell
$ mount -o remount rw system/app
mount: Operation not permitted
Click to expand...
Click to collapse
I searched more and found it can get su permission so to make things work. But when I hit "su(enter)" after open adb shell, I don't see the "#" showing up but still got an error message after waiting for a while
$ adb shell
$ su
Permission denied
Click to expand...
Click to collapse
Any one can please tell what's wrong with my operation? I rooted my G2x but didn't flash it. I installed the ROM manager and installed CWM but didn't proceed to reboot into recovery mode.

you need to look at your phone and allow superuser app to grant permission

su app? how should I set it? I didn't see anyone mentioned that. Do you care to give a bit more details? Thanks.
I think I figured out. I have to manually run the superuser app and let it say in active. Then when I type in "adb shell" the app on the handset will ask my permission. Thanks for the reminder.
Plus I am doing the following as the following that I read from another thread
adb shell
$ su
# mkdir /data/yourname
# chmod 777 /data/yourname
# exit
$ exit
adb push gps.conf /data/yourname
adb shell
$ su
# mount -o remount,rw /dev/block/mtdblock6 /system (copy biggrin.gif)
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock6 /system (copy biggrin.gif)

[i9003][Mod] Root XXKPM without CWM

Hi everyone,
this method helps you to achieve root in XXKPM without CWM (which will be available shortly). You will need the attached files and Linux with installed Android SDK. Credits go to ChainsDD for the Superuser binary and APK and to Skin1980 for his normalboot.img repack script. This method is more time consuming than flashing CWM and more risky. Beware!
Flash XXKPE followed by XXKPM via Odin.
Flash the modified normalboot.img as PDA via Odin and do a full wipe. This enables the adb shell to run as root on the device, allows debugging and mock locations.
Now start up Linux and hook up your device to your PC. Do not forget to activate USB debugging in the settings. Follow these directions very carefully, otherwise you might have to reflash or even loose your IMEI!
Run Terminal. In Terminal, gain root access and start adb:
Code:
su
adb start-server
To be sure adb is running and recognized your device, issue
Code:
adb devices
Now the delicate part: Mount /system read-write:
Code:
adb shell
su
At this point, the "$" at the beginning of each line should change to "#". Otherwise, you're not root and can not continue.
Code:
mount -o remount,rw -t yaffs2 /dev/block/stl9 /system
exit
And now push the Superuser files to the device (I am assuming they are lying in your home directory. Otherwise, adjust the path. For example, "su" could be in "/home/user/i9003/su"):
Code:
adb push su /system/bin/su
adb push Superuser.apk /system/app/Superuser.apk
And finally set the correct permissions and remount /system read-only:
Code:
adb shell
chmod 6755 /system/bin/su
sync
mount -o remount,ro -t yaffs2 /dev/block/stl9 /system
exit
Reboot.
After this, you will typically install busybox from the market. But this is up to you. Have fun!

i really don't know what went wrong the first try, i was getting an error telling me there isnt enough space in the partition where the su binary goes. then again, i simply reflashed kpm, and viola, it works.

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.

Help on pushing files to device (ADB)

Hello guys, experiencing another problem now :silly:
Have search all around, couldn't find any valid answers so I decided to ask myself.
So I was just making a rom, which I have already installed. It's based on Cataclysm (personal use only - Till I ask for perm).
I have installed the rom, then I decided to theme some system files. And so I did. I theme the "Settings.apk" for now, and decided to push it to my device instead of installing the whole rom over again. Now mind you when I made roms and modified system apps, pushing these files to the device was straight forward. However on this Hammerhead, I've been running into some issues.
When pushing the file to my device like this
Code:
adb push Settings.apk system/priv-app
.
I get an error that says -
Code:
failed to copy "Settings.apk" to "system/priv-app/Settings.apk" : Read only file system.
So I then decided to try the following -
Code:
[x] adb root - Permission Denied
[x] adb remount - Permission Denied
So then I decided to use some shell commands to set the system as rw, I did the following.
Code:
[x] adb shell
[x] $ su - gave it permission
[x] $ mount -o rw,remount /system - It mounts it.
I then restarted cmd with root permission.
Code:
adb root"
- it restarted however, this time it stated.
Code:
Device not found.
I probably did the wrong thing above, so how exactly can I push files to /system?
SOLVED
Thanks to everyone that answered my question in detail.
The easiest way I know to push files to /system through adb is using a custom recovery . Try with it.
Why not use usb or AirDroid to transfer files?

Boot into recovery and connect the usb cable. Open a cmd prompt.
Code:
adb shell
mount /system
exit
adb push c:\users\krishneelg3\desktopmyfile /system/priv-app
You can also use the "mount system" option in recovery and skip the first 2 commands above.

Open recovery, mount system partition and connect it to pc and then normal procedure.
It will be running as adbd to no need to type adb root. Hope this helps

You can still do it through Android, but it's more difficult because adb root doesn't always work (requires kernel) and you have to mount r/w which is just a pain. I always adb push in recovery.
However, here is an example of a successful attempt to adb push on my nexus 5.
Code:
C:\Users\rootsu\Desktop\tools>adb root
adbd is already running as root
C:\Users\rootsu\Desktop\tools>adb shell
[email protected]:/ # mount -o remount,rw /system
mount -o remount,rw /system
