Removing app_s from /system/sd

Hello all, I am trying to remove the app_s folder from /system/sd using terminal emulator. I typed in:
$su
#rm -r /system/sd/app_s
but I get a long list of everything in app_s saying:
rm: cannot stat '/system/sd/app_s/name of app/widget Stale NFS file handle
can someone help me with the commands I need to remove that folder? I unfortunately don't have adb

Helppp removing .apks with sdk method

i try this on the comment prompt while phone running.
cd\sdk
cd android-sdk-windows
cd tools
adb devices
adb shell
#mount /dev/block/mtdblock4 /system
cd /system/app
ls
i get all the apk. files
i try removing an apk.file
typing this syntax:
rm -f thenameoftheapp.apk
and it'll say:
rm failed for -f, read only file system
it wont let me write on the system im guessing.
Now i tried doing the same thing but phone mode is on recovery.
I have the nand protection unlocked so when i get to recovery mode
i have already the custom recovery setup showing, i don't run the recovery-windows.bat.
now when i type this on the comment prompt
cd\sdk
cd android-sdk-windows
cd tools
adb devices
adb shell
#mount /dev/block/mtdblock4 /system
cd /system/app
ls
i get all the apk. files
i try removing an apk.file
typing this syntax:
rm -f thenameoftheapp.apk
after i hit enter it shows me
#
so im assuming the apk. has been removed
after i exit the comment prompt and i wipe the dalvik-cache
i reboot the phone and all the apps i removed are still there and running still.
help please

need write to /system or something EXEC path

I was the first person I know on the internet to compile nmap for android and this guy ( http://wjholden.com/nmap/ ) took it to the next level got a new phone ( CM6 with OC ) nbow it does not work
* can't write to /system even with rw remount
* if I boot recovery I can' write to /systm but its just a temp fs so failsause ...
* can't ADB shell (read below ) to find out where system is really mounted OR mount the real /system my self ..
* remouted / but anything I add gets wipped on reboot ...
* onlything that works is remount / , copy nmap and then add PATH hackery to EXEC nmap ... on EVERY reboot ...
NOTES BELOW:
Code:
http://forum.xda-developers.com/showthread.php?t=701589&page=4
I think its because /system is protected in CM5+ ? even with remount
command... ?
let me know what I need to copy where in recovery mode to /system to
get yours to run properly :/
you could also have your installer check for this and have notes etc ..

You can't write in /system in normal boot mode as security is on (s-on), remounting rw does you no good.
In recovery you will need to mount /system from clockwork before you can do anything.

I do have Clockwork Recovery 2.5.0.1 but I am not sure how to get to a shell and or find /system mount path as I can't adb shell ( read above ) so I can't remount or mount /system
rmccurdy.com/nmap.sh * this is what I am using for nmap as of now ..
Usage:
bash -x /sdcard/nmap.sh localhost
etc ...

There's an option in clockwork under partitions to allow you to mount the system. I'm not sure why but a lot of people have an issue getting into su with adb when they are in recovery, the constant /system/bin/sh error is annoying. Also, if I remember right, yaffs2 is not what you use to mount the system when using that command. It's mtdblock3 or something like that if I'm thinking along the correct lines here.
Maybe you should try putting it in a zip file as a script and running it that way since you use a different command (and much easier) to mount the system and write to it. Then again, I'm not sure what you're trying to so so I could just be talking out of my a$$

I can't do anything usefull in recovery ... reboot and apply update.zip but I dont how how nor do I really want to make a .zip / script to mount system etc .. do you know a zip I can work from as an example

The slide doesn't have S-Off, most HTC phones have them now...So you have to wait for Alpharev 2.0 to be released.

Yes, but in recovery we can mount the system and write to it. Phones with s-off can do that while booted normally because the NAND is unlocked and the system is no longer protected.
You can do it one of two ways. This one is easiest if you know linux commands but are unfamiliar with update-script format. Make an update script and put this in there:
Code:
show_progress 0.5 0
run_program PACKAGE:example.sh
show_progress 0.5 10
You don't have to use the show_progress line, it's just for aesthetics.
Make a .sh script, name it whatever you want and put the linux commands you want to execute in the script. For example:
Code:
#!/sbin/sh
#
##############################################
mount /system;
rm -rf /nmap
mkdir /nmap
echo 'export PATH=$PATH:/nmap' > path
cd /nmap
wget http://rmccurdy.com/stuff/G1/BINS/NMAP/NMAP.zip
unzip NMAP.zip
chmod 777 /nmap/*
export PATH=$PATH:/nmap
echo run /nmap/path before you start nmap
nmap -vvv 127.0.0.1
exit 0;
Or what ever you're trying to get done. I'll upload an example file of all this since hands on is always better. Looking at this though, you may want to have the files in the zip (in the directories they will be installed to) because wget probably wont work since the radio is off while in recovery.

interesting thanks ! ... do you have to resign it and all or can you just edit and rezip it ?

As long as you're using clockwork you just edit and zip. Might be easier to use an archive explorer to open (without uzipping it) then drag and drop, but do what's easiest for you.

[Q] /system/bin 100% full?

Hi,
I unrooted and ran the 4.5.141 update. I'm now on Android OS 2.3.6. I am now trying to follow the directions to re-root from here: http://www.android-advice.com/2012/root-the-motorola-atrix-4g-running-4-5-141/
However, when I get to the step where I run the command:
Code:
cp /preinstall/su /system/bin/
I get the error "cp: write error: No space left on device" which I thought was very odd....so, I ran the command
Code:
df /system/bin
and the output I see is:
Code:
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/block/mmcblk0p12
326071 326068 3 100% /system
Is this possible? How do I get su back on to /system/bin?
How can it be that the /system partition is full? Is there a way to resize it, if that's the case?
Please help!!!

did you do step 6 before step 4
check this out THIS

Obviously, otherwise it won't work. My problem is that /system has no free space. How is that possible?

a simple 'yes', without 'tude, would have sufficed.

Ok, here's what I had to do to make this work. First, you have to check if you have Superuser.apk saved in /system/app. If you do, delete it (you'll reinstall this later).
Since I also wanted to install the latest version of Swype, first, rename /system/lib/libSwypeCore.so to /system/lib/libSwypeCore.so.bak
Then, cp /system/app/Swype.apk /sdcard/Swype.apk.bak
After you've copied the stock Swype to the sdcard, then rm /system/app/Swype.apk
This should provide you with enough room on /system to cp /preinstall/su /system/bin/su
The rest should follow accordingly.

Copy Files programmatically from SDCard to /System help?

OK, So I'm developing this app Specifically for CyanogenMod that Copies a few apps and Sound Libraries to a few Different folders in /System. After the Files download into a folder in the Internal Storage of the Device (An LG L90 running CyanogenMod 13), /SDCard/CmSoundMod, it extracts all the zip files into /SDCard/CmSoundMod/unzipped/*Library Name Goes Here*/ with a separate folder for each Library. I'm trying to copy an example file from /SDCard/CmSoundMod/unzipped/SystemFiles/sample.txt to /System to test it out but All the Methods I know are not working! Ive tried using
Code:
Process p = Runtime.getRuntime().exec("su", "cp -r sdcard/CmSoundMod/unzipped/SystemFiles/sample text /System");
(I mounted System RW, and Remounted RO when finished this is just the main code used for copying)
Can some one point me to a piece of code that works for them? (Java)
Thanks!

try with this:
Code:
Process p = Runtime.getRuntime().exec("su", "cp -r sdcard/CmSoundMod/unzipped/SystemFiles/sample[color=red]\[/color] text /System");
the android terminal is based on the Unix terminal. and in a Unix terminal the space in the name of file or folders is not recognized, you need to replace it with "\ ".

sorry I made a mistake:
Java does not recognize the back Slash then you replace '\' by:
Code:
\\
I try on my device me it works!
Code:
Process p = Runtime.getRuntime().exec("su", "cp -r sdcard/CmSoundMod/unzipped/SystemFiles/sample[color=red][b]\\[/b][/color] text/System");
