ADB Uninstall Failure

I adb pushed some .apks from a Froyo zip onto my mytouch1.2 but they didnt work...
when I try to uninstall them I get a failure message... and when I try adb shell... blah blah blah..."ls" the files arent there...
any help is appreciated

how to uninstall
I've tried a few methods.
The one I've found that works the best is this : mv <source> <destination> ...it's supposed to be a move command but it actually deletes files. rm also likely does the same (eg rm <filename.filetype OR foldername>)
BEFORE using these commands though, type in
adb shell <enter>
cd <foldername> <enter>
cd <foldername> <enter>....to get to folder (directory) of your choice
**TO get to app directory to uninstall apps, do cd system -->cd app -->mv appname.apk
I use the /sdcard as the destination for the mv command - I noticed the files NEVER get moved so this is just a delete command.
You could also delete a whole folder with this command. do cd system
mv app /sdcard
(this would delete the entire app folder/directory from the device).
That's pretty much it. Works for me. Was trial and error though - adb uninstall command ALWAYS resulted in 'failure ' or 'file not found' and the same with adb shell --> # uninstall appname.apk ---> 'failure'.
So I hope this works for you! Good luck .

NOTE: I've had an awful time because my stupid tablet has refused to download things from the market. It stalls in the initial 'starting download' bit and then just hangs, and then says 'download failed'. Apparently there's some problem with the sync'ing but I can't log into Gmail or GoogleTalk to try to resolve this (Gmail won't allow me to enter anything - left it on overnight and it said 'getting mail' / 'sync in progress' and the sync never completed after 12 hrs. The GoogleTalk app just displayed a black screen. So I am getting nowhere.
if anyone knows how to fix this pls let me know. I'm apparently not the only one. Others /various tablets have had similar issues - I have a 7" BPDN (Pandigital black novel).
Please, help!

adb shell <enter>
then
cd system
cd app
mv <filename.apk> <destination> (this should move the file BUT it never shows up in destination or elsewhere, so this is effectively a delete command, you could also do mv <foldername> <destination> to delete a whole folder.
**I usu. use /sdcard as my destination. so mv filename.apk /sdcard
OR
cd system
cd app
rm <filename.filetype> does the same sort of thing.
(eg adb shell <enter>
**I tried the uninstall commands listed but.. (adb uninstall-->'failure', or 'file not found' etc, adb shell --> uninstall --> same error).

Commands for removing apps.
I run as root on all my OS's, so I don't have to navigate to my sdk directory. I just type "adb devices", I don't know how your adb is setup, but get adb running and run these commands.
adb remount
adb shell
rm /system/app/whatever.apk
Or whatever path you pushed the files to. Try running fix_permissions to make your apps run properly and stop FC issues

how do you change folder permissions???

hi
how does one change folder permissions? i have read that you cam do it with the root explorer app but is there a way to do it on the pc using the sdk? i connected my phone to the pc and issued the adb shell command and then attempted to use the chmod command but got a read only file system message.

1) If you have ADB setup on your computer, hook your phone into the computer and connect into it via ADB.
2) Once in, "chmod" the directory or file(s) you wish to change permissions for.
IF you don't have ADB:
1) Download a terminal
2) su - to root
3) Change your directory
4) "chmod" to whatever pemissions you want

it means that folder/file you're chmod'ing was mounted ro. you cant change anything if its mounted as ro. to check just enter "mount" and you can see what are mounted as rw, ro etc

I would also suggest changing it back when you're done. This helps prevent you from accidently overwriting or deleting something and have to reflash if you're rooted.

[Q] How to unroot phone Atrix 2

I used the eacy one click to root phone. I would like to unroot it now. I am having touch screen freezing problem. I need to start removing applications to see which one is causing the problem or if it is a hardware issue or software.
I downloaded the zip file 1-click_exploit. I expanded the files and ran the application. I have read that there is an option to uninstall with in that file but I don't see one. Where do I find it. If I just do a factory reset will it remove it? If I do a reset do I have to repurchase all of my apps?
Thank you in advance!

A factory data reset will not remove root.
Also, a reset does not delete your purchases. They are all stored in your google account. So, if they do get deleted, just reinstall them.
As far as unrooting, I do not know. Someone else may chime in here...probably going to tell you to post in the Q&A section as well.

Doesn't the one-click have an un-root feature?

The one click method also has an un root option in the folder.

Generally the only trace rooting leaves is a setuid binary "su" in /system/bin. And Superuser.apk to manage permission which apps get to invoke the binary. So unrooting involves uninstalling Superuser application and removing the su binary. If you want to do it by hand: (1) adb remount (2) adb shell (3) su (4) rm /system/bin/su

I have no idea what the above manual steps are for. I can uninstall the application but where and how do I remove the su binary. On the phone? Please send directions for a non technical type of user.
Thank you!

Not sure where in the the following files in 1-click_exploit is the unroot option.I have attached a list of the files in the download.

Out of these files, adb.exe and .dll files are left in your windows PC. Not sure if they are deleted afterwards, if not, you can always unzip the above into a directory. You'll need the adb and the dll files.
The su and superuser.apk are two files that are pushed to your phone that provides the root functionality.
The zerg file is the exploit payload temporarily used to root your phone, and removed later by the script.
So if you have unzipped these into a directory, connect your phone via USB (make sure usb debugging is on), and run the commands
Code:
adb.exe remount
adb.exe shell
su // superuser may pop a permission request on phone screen
rm /system/bin/su
rm /system/app/Superuser.apk
exit

What mode is my usb connection? charge only? I have the phone setting usb setting on. I run the commands (using the run command in windows accessories). When I go run "adb.exe remount" the black command screen blinks on screen so then under I go to run again and entered "adb.exe shell" the run command screen opens up with [email protected]:/$ I put in "su" After I entered the command rm system/bin/wu I get a "read only error" how do I change from read only?
Sorry for all these questions but I warned you that I was not a technical user. Thanks

I was wondering do I have to have the elite version superuser installed to grant permission to system? I just have the free version.

1. yes -- charge only
2. it is better to open a command prompt -- in run commands type in "cmd" which'll give you a shell, easy to track command outputs
3. in that shell cd to the directory you unzipped and run "adb.exe remount"
4. Unless it says "remount succeeded" further operations won't succeed
5. After you execute "su" your prompt will change from $ to # ... is this happening?
6. Only on # prompt, you can do "rm /system/bin/su" ... that too only if remount succeeded
Let us know at which step it fails.

I get the following error after entering the run "adb.exe remount"
*daemon not running starting it now*
*daemon started successfully*
remount failed: operation not permitted

Then try remounting manually:
Code:
C:\> adb.exe shell
edison$/ su
edison#/ mount -o remount,rw /dev/block/system /system
Afterwards proceed with rest of the script.

[Q] cant copy big files (via USB-MTP, ADB)

hey!
I try to backup my backup. So I want to copy my nandroid-files from internal-SD to my computer. everything is working fine, but the two big files from data (810MB) and system (1200MB) cant be copied. If I try it with normal USB-MTP windows just ignores my copy-attempt. With adb pull I get an error:
adb pull sdcard/TWRP TWRP
results in copying everything instead of system and data: "failed to copy FROM to DEST: Permission denied"
any ideas?
I'm using JMZ-kernel, dev-unlock, root.

forgot to say: Also no access via Airdroid and ES Explorer/Root Explorer. I tried to copy those files somewhere on the SD-card, also tried to put them in a zip file.

The backup is in a special folder with protection, so you need to set the correct rights to copy the files, I think.
You may use these commands in Adb console:
adb shell
su
chmod -R 777 data/media/0/TWRP/
exit
After this it is possible to copy the files

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>
