Imposible to uninstall APPs with adb - General Questions and Answers

I need help, I want to uninstall some applications from my phone with adb, but typing the command: ". \ Adb shell pm uninstall --user 0" app_to_remove ".
I get the error: "Failed to remove package from user owner's system."
I follow the commands correctly from beginning to end, but it does not allow me to uninstall applications, my phone is an "Alcatel 1 5033e
.

1. The command used is unusual. It should be adb uninstall <PKG-NAME>
2. Apps housed in /system partititon can only get uninstalled by ROOT user and if partition /system is mounted as RW ( means: Read / Wrire access )

how can you how can I get root access from adb?

Install a temporary ROOT.
Example
Code:
adb devices
adb push <LOCATION-OF-SU-BINARAY-ON-COMPUTER> /data/local/tmp/
adb shell "chmod +x /data/local/tmp/su"
adb shell "/data/local/tmp/su -c '<SHELL-COMMAND-TO-GET-RUN-HERE>'"

[Q] Write, Execute Permissions

I have been googling far too long for an explanation of how to change the Read, Write, Execute options on individual system and data apps, when I remembed how fast someone usually answers my n00b questions here. It is not even clear to me what the differences are between the Write and Execute options. Can someone give me a link to a tutorial regarding this?
I did read the suggested threads, not helpful, and one I didn't understand about remounting the "entire /system partion to read-write".
thanks. d
To be more specific, I want to change the permission on certain system apps so I can uninstall them.
If your phone is rooted then you need a file manager that will remount the system partition as RW ( read write). Or you can use adb with your first command being adb remount.
Sent from my HTC Vision using XDA App
As ESKIMOn00b started to explain, the process of removing apps from the /system partition isn't a matter of individual file or folder permissions. Android secures the /system partition by preventing it from being written to under normal circumstances. If you have rooted your device then you have the ability to become the root user and run most if not all commands.
ADB provides a nice convenience command, 'adb remount', that will allow you to modify the /system partition. This command will only work if you have root user privileges but will unlock all of the apps for you to remove. Be careful though, you shouldn't just delete APK's directly out of /system/app as the package manager in Android might not keep up with your deletions. The best way to go about it (after remounting /system read/write) is to use the 'pm uninstall' command:
# pm uninstall com.myapp
To figure out the package names you can use 'pm list packages' and it will dump a huge list of all installed apps on the device. You'll need to hunt through and find the right ones. Most developers use obvious naming schemes such as Amazon's MP3 Store: com.amazon.mp3.
Hope this helps!

I have root and some recent experience w/the AndroidSDK. Using the SDK on my SonyEricsson phone:
c:\Users\dSpr> cd c:\AndroidSDK\tools
c:\AndroidSDK\tools>dir
{list}
c:\AndroidSDK\tools>adb devices
{0123456789ABCDEF device}
c:\AndroidSDK\tools>adb ls /system/app
{list}
c:\AndroidSDK\tools>adb shell
$ pm list packages
{list}
Note the shell command produces a $ instead of a #, but it still gives me a list.
But w/the $ and the command adb remount this:
$adb remount
adb remount
adb: permission denied.
If: tools>adb remount
This: remount failed; Operation not permitted
Same operation w/my QT7 and tools>adb shell produces a #. In fact, I don't even have to I don't have to use the adb remount command on my first uninstall, just
#rm /system/app/{app}.apk
#pm uninstall {package name}
I don't recall that I used the remount command between uninstalls-don't think I did or I would have noted it because I was keeping careful track of what I was doing. I can't test it because I have no apps on that device to uninstall.
Get the same result when using the terminal with the su command on the phone itself.
This is why I thought I had to change the Read/Write permissions.
What are you telling me that's not getting thru.
Thank you both very much.

to remount your system, you can try this
Code:
adb shell
Code:
su
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system

Nope. adb shell results in a $. su results in a su w/out the $ and after some (close to a minute) hesitation: Permission denied $
Debugging is on, as is mock locations. I am also having the exact same problem with my new enTourage Pocket eDGe, but it isn't that bothersome because it doesn't have a lot of garbage like the cell phone.

How do I install netflix patch

Hi,
I am rooted now (I guess/hope) I would like to fix it, I have the patch and have tried to copy the libnvomx.so to the lib dir n my TF using file manager HD, but it wont let me paste it, I dont have or seem to have access.
also, is the libnvomx.so the only one I need to copy from the patch?
does this mean I am not rooted?
Is there somewhere/link where I can learn how to, and what terms like adb, push, clear the cache sideload, quickboot, recovery, etc... mean? (search hasnt helped me much with the ones I have looked for, too many results or too few)
thanks for any help,
John
use the terminal emulator, and make sure you "su" before you try to copy.
Another option is Root Explorer: https://market.android.com/details?id=com.speedsoftware.rootexplorer
Root Explorer will allow you to establish write access to system files. It's what I used to get Netflix working on my Transformer

Hi,
Thanks, what is su?
I tried using adb (at dos prompt) I tried
adb push libnvomx.so /system/lib/
it said read only access
will the su give me access? how do I su?
I am not even sure what the terminal emu is?
thanks,
John
I don't know if your rooting added the terminal app to the tf101.
You need to run the su(superuser) command to gain access to the system files.
I think you can run it from adb as well, if you used adb to root, then you probably already used this command.
you can also just download the netflix patch zip to the microsd card, and install the zip from cwm recovery mode.

Close, no cigar:
try this:
adb remount
adb pull /system/lib/libnvomx.so libnvomx.so.orig
adb push libnvomx.so /system/lib/
adb chmod 644 /system/lib/libnvomx.so
adb remount
adb reboot

I'm not recalling if you can do an adb chmod, but probably you can so I'll add that in up there just in case it works: Also I added a bit where you get a copy of the original in case this all somehow goes bad.

I havnt tried yet but will asap. Where did you learn this stuff? I was reading this thread (I finally looked in general)
http://forum.xda-developers.com/showthread.php?t=872128
It has some info but real detailed, like in your script, the "chmod 644" the 644 part. I guess it takes time, I ave only had this TF for a week or so and it is my first android OS.
thanks again, (I will let you know when I try,

Just wondering before I try this, the pull command (Is that backing up the libnvomx file to the pc?
after reading the thread linked above, wont I have to be in adb shell to geet permission to copy the file to the lib dir?

I used nvflash and adb to install busybox and superuser and su.
I dont know anything about su or superuser, I havent found any threads with info on them yet.
thanks,
It might sound confusing but this is just all basic linux.
when you're running the adb shell just enter su. This gives you permission to edit the /system files
Then pull(copy) the file from your tf101, to your local machine. this is a backup.
Then change the permissions on the file on your tf101.
Then push the new file from your local machine to your tf101.

Hi,
I broke down and used your script, I tried doing it on my own but kept getting errors. I did seem to get one error in this line of yours
adb chmod 644 /system/lib/libnvomx.so
when I ran it (and I copy and pasted it to dos window)) it gave an error, well not an error but it listed commands and switches like if there is a typo. I dont know if it took the command or not here is a paste

Oh, so the android runs linux, or a version of it (like ubuntu, freebsd, etc...)? that should help me a lot. I installed ubuntu on one of my PC's a few years back but they didnt have drivers for sli and raid for my system at the time, I played with it a day or 2 and went back to MS. It has always been on the list to do. I am going to have to try it again.
I just looked, it looks like there are lots of new "distro's" (versions) now a day from back when I tried it.
anyway, thank you very much for the help,
John
once you did this:
C:\ADB>adb push libnvomx.so /system/lib/
1174 KB/s (164764 bytes in 0.137s)
you already copied it, so you must have already had permissions. Therefore this next command:
C:\ADB>adb chmod 644 /system/lib/libnvomx.so
Android Debug Bridge version 1.0.26
was redundant anyways. I suspect you needed to run
adb shell chmod 664 /system/lib/libnvomx.so
for adb to run the command on the transformer(shell) rather than in the dos directory.

I see, so shell is like I am running it in/from the TF. I guess that is why push and pull doesn't work in shell, it could be confusing??
I downloaded/installed root explorer but I would rather learn it the harder way.
thanks again for your help!!

Cool. I wasn't sure about the "adb chmod" working since I'd only done that from a linux shell before this, but it was worth a shot. If you went into adb shell, then typed "mount -o rw,remount /system"; chmod 644 /system/lib/{whatever that file name was}; and mount -o remount,ro the thatt that would work", or I suspect he is right about how you can use "adb shell chmod 644 /../../.....".
Anyway, glad it worked out.

Hi,
If I shell, do su, then exit the shell (which I couldn't figure out how to do) do the su rights still apply, if I then use adb commands?
mount and remount, I see those are for mounting partitions, do the partitions each have different rights? and what does chmod do?

If you did an $su ; # inside the shell (adb shell), then when you typed in exit, that'd exit the shell, and cause any subshell's kicked off with a command (like "su" to pick one from a hat), to 'go away', So no, you wouldn't still be su.
But: There is a 'switch' or setting somewhere that brings up the adb shell in # su mode, but it escapes me right now.
Mount -o remount,rw||ro /{mountshare} (one command) will just remount some partition like system as you direct it to. It will 'outlast' the adb session. If you leave adb after doing a mount -o remount,rw /system, then you've left /system mounted rw. It doesn't hurt anything, but in theory you type in $sync; sync and $ mount -o remount,ro, and then the clean police will be happier.
chmod changes permissions. You could look up the man page on google, and it'll show you that you have 3 groups, owner, group and world. You could do the command in a couple forms, like #chmod {permission mask like 777} {filename} or chmod w+x {filename} where first one gave all permissions (rwe/rwe/rwe) to some file, 2nd gave the world execute permission.

HOW to root qubo big one

i got a new qubo big one and wanted to root it
Your phone's Android OS is rooted as soon as the cmdlet named su - what by default is left off - is present in Android's file system and executable.
Hence add a suitable version of su to Android OS: can be done via ADB.
Please can I get a step by step

A: To run Android shell commands with super-user right from within the shell on desktop computer ( AKA Command Prompt ) you have to run within desktop computer shell
Code:
adb devices
adb push <LOCATION-OF-SUITABLE-SU-BINARY-ON-PC-HERE> /data/local/tmp/
what will 1. connect the Android device to your desktop computer and 2. upload the su binary in the Android device temporary directory always available for the user.
B: Then, in desktop computer shell type
Code:
adb shell "cd /data/local/tmp & chmod 776 su"
what makes the su binary executable: its ownership by default is set to shell.
C: Then in desktop computer shell type
Code:
adb shell "ls -l"
what will show you content and permissions on recently uploaded files.
D:
To apply a series of Android shell commands what require super-user rights you now would run

Easiest way to temporarily get root on Android

Hi
I have a new Android device, it's not any of the ones that have their own forum.
More specifically it runs Android 11 on top of a 4.19.193 Rockchip BSP kernel.
I need to read one or two specific files but these files are only readable by root.
I have ADB shell access.
What I do want to acheive:-
Temporarily have an ability to copy a file that's readable only by root, this could be by some GUI app that copies files, as long as the copy is readable by normal user, running commands as root, copy a partition to an image file, export to a desktop machine and read it there. Any one of these would get me that file.
What I don't want to do:-
I don't want to permanently modify the device, unlock the bootloader, put su into /system or anything like that.
Does anyone know of a rooting app that can give me temporary root access but then doesn't actually change the system?
thanks
To get temporary super-user ( AKA root ) rights on an Android's device shell all you have to do is to find a suitable su binary and copy it onto Android's filesystem.
A: To run Android shell commands with super-user right from within the shell on desktop computer ( AKA Command Prompt ) you have to run within desktop computer shell
Code:
adb devices
adb push <LOCATION-OF-SUITABLE-SU-BINARY-ON-PC-HERE> /data/local/tmp/
what will 1. connect the Android device to your desktop computer and 2. upload the su binary in the Android device temporary directory always available for the user.
B: Then, in desktop computer shell type
Code:
adb shell "cd /data/local/tmp & chmod 776 su"
what makes the su binary executable: its ownership by default is set to shell.
C: Then in desktop computer shell type
Code:
adb shell "ls -l"
what will show you content and permissions on recently uploaded files.
D:
To apply a series of Android shell commands what require super-user rights you now would run
Code:
adb shell
export PATH=/data/local/tmp:$PATH"
su -c "<SHELL-CMD-HERE>"
....
su -c "<SHELL-CMD-HERE">
exit
BTW:
When in an Android shell another process like su gets started then this spawned process runs as a child process means it inherits most of the parent process attributes.
adb push allowed me to send the file
Code:
adb push su /data/local/tmp/
su: 1 file pushed. 1.2 MB/s (11640 bytes in 0.009s)
but the adb shell command is failing
Code:
adb shell "cd /data/local/tmp & chmod 776 su"
chmod: su: No such file or directory
if I then log in over adb I don't seem to have permissions to do anything in data
Code:
adb shell
ls -al
drwxrwx--x 47 system system 4096 2022-09-02 16:31 data
cd data
ls -al
ls: .: Permission denied
additionally, I thought that su would need the suid bit set
Does chmod 766 acheive that?
oh this works
Code:
adb shell
cd /data/local/tmp
ls -al
total 18

The device has separate boot_a, boot_b, dtbo_a, dtbo_b partitions.
If I could be reasonably sure that booting a boot partition from a similar device (I have one) would pick up the dtb from this device then I think I could be reasonably confident of not frying anything, I might try and boot it from fastboot.

Disable system packages [ADB - Android 13]

Hi...
I made the very bad mistake of updating my Oppo Reno 6 5G to ColorOS 13...
There is no possibility to downgrade and moreover some packages can no longer be uninstalled or disabled via ADB.
For example, if I wanted to uninstall/disable com.oplus.ota to avoid further updates, the ADB commands that worked until yesterday would no longer work...
Es:
shell pm uninstall --user 0 com.oplus.ota
Failure [DELETE_FAILED_INTERNAL_ERROR]
shell pm disable-user --user 0 com.oplus.ota
Package com.oplus.ota new state: default
shell pm disable com.oplus.ota
[Error]:failed to disable com.oplus.ota
Anyone has a solution? Thanks....
Is the mentioned file listed as package?
Code:
adb devices
adb shell "pm list packages -s"
If not then you can't use pm cmd to operate on this file.

Yes the package is in the list! However both the disable and the uninstall give the error...
If one wants to get completely rid off of a system-package he/she
1. must make /sstem partition RW - what requires Android is got rooted
Code:
su -c "mount -o rw,remount /system"
2. simply runs
Code:
su -c "rm -f /system/<package-name>"

hallo, i've been using this method from a2.3 to a11 to uninstall system apps, but this method is not useable with a11 in a TWRP shell, so i'm curious, are these steps still works correctly in a13? in a system shell or TWRP shell?
The code excerpt printed above is meant to be run via ADB as
Code:
adb shell 'su -c "mount -o rw,remount -t auto /system"'
