hello
I have a problem
delete the build.prop to modify
and try to put it back I get an error
commands are used to delete build.prop
adb shell
$ su
# Mount -o rw, remount / system
# Rm /system/build.prop
and to try to get him back
adb push
and the result is
failes to copy "build.prop" to "/system/build.prop": Permission denied
if there is a way to introduce build.prop back to your place
and they know it
I would be very grateful!!!!!!!!!!!!!!!! :crying:
Hi, thank you for using XDA Assist. Probably the best thing to do is flash the stock firmware. But i don't know what device you have so can't help you with that.

+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

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

Hi
I have Huawei u8150, Android 2.2, Rooted with z4root.
I want to give widgetsoid access to toggle data using the android apn toggle.
The instructions are:
____
Just put the Widgetsoid apk on /system/app folder
Work only with ADB connected to the phone (doesn't work if you use root explorer or other apps like this) :
* Remount /system as read/write
* adb push Widgetsoid.apk /system/app/Widgetsoid.apk
* Remount /system as read-only
_____
Can someone tell me what I can type in terminal emulator window to achieve this. I can't use adb as it won't recognise my u8150 (It worked fine with my i9000)
Thanks

I had tried
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# CHMOD 777 /SYSTEM
the above works but if i try to push i get
# push
push: not found
I also tried the above then switched over to es-file explorer and was able to copy + pasted the widgetsoid.apk file from my sdcard into the /system/app directory. It correctly pasted the file, but when I clicked on widgetsoid.apk to install the apk i got an error.
"Parse Error: There is a problem parsing the package."
I wouldn't chmod /system ... just leave the permissions the same.
cp /sdcard/downloads/widgetsoid.apk /system/app/
Chmod 644 /system/app/widgetsoid.apk
No need to click install or anything like that... just reboot after copying it to /system/app.

push is an adb command. You'll want to put the apk on the sdcard then use:
cp /sdcard/Widgetsoid.apk /system/app/
That will copy it to the directory.
Nevermind, do what jeffv2 said.
THANKS! it's working now.
I had placed it in /system/app and did a reboot and it still hadn't installed
then i renamed the file from Widgetsoid2.x.apk to Widgetsoid.apk and also did chmod 644, after a reboot it has successfully installed.
I think it was the chmod 644 to the apk file that allowed it to be installed
Many thanks!
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)
# mv /data/yourname/gps.conf /system/etc

I've been working on my /System/App folder with root access and I changed the permissions to R/W, R and R. Afterwards, the device freezes at the AT&T screen, looping at the stage where it loads certain apps. It attempts to load them, but because it can't access them due to permissions, they freeze and then force close. I'm rooted and have CWM installed, so I have ADB access. I'm using the UCLD2 ICS build, and my question is this:
I know that it's possible to change the permission of folders in the root folder using chmod, but I've had no luck with this so far.
Using ADB shell, and these are the commands that I've been using:
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
chmod 755 /system/app
I've got it mounted, but when I chmod, it tells me "No such file or directory"
If I can change the permissions on the /system/app folder back to the way it was, my phone'll be fine, but right now, fixing permissions doesn't solve the problem, and I'm stuck in loop for now. Any thoughts would be appreciated. I've read through multiple forums and the closest I came to finding my problem was with the Kindle Fire forum, and I've been trying to carbon copy the solution from that forum. http://forum.xda-developers.com/showthread.php?t=1389728
Any help would be appreciated =)
Sorry for the post...I answered my own question. I rebooted recovery and restarted adb.
I ran this as follows:
adb root
adb remount
adb shell chmod 777 /system/app
This did it!
Sorry about the spam on the thread =)
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?

Is it possible to push files to /sustem/priv-app with it?

How would I do so? I've ever only used recovery to flash. And that was it, thanks if you can guide me through it?

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

exit

Thank you I will keep my eye on this and see if the process is similar. Thanks for the info.
