The proper way to remove a system applications - myTouch 3G, Magic Android Development

Dears,
I'm using the last Cyanogen and I would remove some applications that stay in /system/app. I know that I can do this just with:
- rm /system/app/NAME.apk
- rm -r /data/data/NAME
but in this way the application data remains in /data/system/packages.xml: I don't want to manually change this file. Is there a more clean and automatic way to do that?
For the applications in /data/app, I can use 'adb uninstall NAME' but it seems that is not appliable to the ones in /system/app. Even after a 'adb remount'.
Any suggestions?

Just delete them.

anyone knows?
i wanna get rid of the default IM.. and amazon mp3

I repeat myself: Just delete them.
It isn't dangerous or "unclean".

Just be a little aware that some apps might seem superfluous, but actually do things other than the part you see. For example, you can't delete the stock Mms.apk and use ChompSMS as your sole SMS application - the stock app also contains the framework for the device to receive SMSes at all. I would rename files rather than deleting them, i.e.
mv thingyouwanttodelete.apk thingyouwanttodelete.old
rather than
rm thingyouwanttodelete.apk
because you can always then put it back afterwards if you find something doesn't work afterwards.

I think Cyanogen latest rom has the system app's folder as read only. So you would need to remount the drive as Rewriteable to make any changes to the files.

what are the steps to remount as rw?

-bash-3.2$ ./adb remount
remount succeeded
adb remount - remounts the /system partition on the device read-write
adb root - restarts adb with root permissions

You can delete stuff in the update.zip then just resign it. I wouldnt delete any com.**** stuff or htc.**** except widgets(on hero) always copy the update zip before you start editing so you can always add what is needed

Start asking your questions in the right sub-forum (Q&A) (Theme) or even in (General), or i will be forced to ban you for 3 days or till you learn.

Deleting system sounds

Was just wondering if anyone has deleted ringtones, notification or alarms successfully? `ould love to get rid of them if possible. Tried making a copy of jf rc30, deleting them and amazon apk then installing but didn't work gave me error message.
i removed unused ringtones w/o any issues
If you have JF's RC30 1.31 installed you should be able to just delete them. Astro should let you goto where they are saved and just delete em. You may need to use DroidSans Tweak tools to remount /system as read/write first.
Hmmm, changing to read/write and trying to use Astro gave me "error deleting file"
Any other ideas?

Word let me know if this works. I asked in another thread how to do it but no one answered. All I got was the "yes you can delete them" response
I deleted all of my ringtones without any issues. Just use adb shell and remove them. You can also "pull" them first if want to have a backup. In adb shell type "cd /system/media/audio/ringtones". Now you are in the ringtones folder, now type "ls" and then a list of all the ringtones will display. Once you know the name of the one you want to delete just type "rm filename.ogg" and thats it.

Worked great thanks!
No problem, that was one of the first things I did was to change all of the ringtones. Couldn't stand the ones that came with it.

Yeah i hear you on that, just a bunch of crap taking up space. I use mp3's for ringtones so no need to waste system space on them! I just learned how to use adb thank god!
Update - deleted most of the ringtones and 4 notifications, freed up 2mb's

You can do it all right from the phone with Terminal.
Type
Code:
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock03 /system
cd /system/media/sounds/(whichever directory you want)
ls
rm (whichever .ogg file you want)
The .ogg files are case sensitive, so beatplunker.ogg isn't the same as BeatPlunker.ogg
Also the .ogg extension has to be at the end of each file you rm.
If you want to save a backup on your sd card I just typed this before I started removing things. Good luck
Code:
cp /system/media/sounds /sdcard

In the future, you may what to do this through your PC to prevent carpel tunnel... You can download the Android SDK from here: http://developer.android.com/sdk/1.1_r1/index.html
Extract it to your drive. Navigate to that folder in a command prompt window then "tools". Once there you can run(make sure the G1 is plugged in the usb):
adb remount (remounts the system read/write)
adb shell (this drops you into the shell to interact with your phone)
cd /system/media/audio/
From there you should be able to follow the proceeding directions.
I went and did all this and even went the extra mile and pushed some of my custom mp3's to the file (about 3 meg worth). Is this going to cause problems with updating in the future?
You don't need to remount the system to read/write manually if it already has been done with DroidSans do you?
I usuall y do the mount through Terminal emulator.
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
rm -r /system/media/audio/ringtones
rm -r /system/media/audio/notifications
bam gone!
I tried to copy and after mounting I typed:
cd /system/media/audio/
ls
then got:
alarms
ringtons
notifications
ui
then I typed: cp /system/media/audio /sdcard
and got this message:
cp: omitting directory '/system/media/audio'
is it something small and dumb that I'm doing or are the files copied?

this can come in handy for the hero roms if u use the facebook feature quite often under the people app. i know i tend to show people certain pics of me or friends and it just eats up internal memory. all i do is clear the cache but if i can use this script to do so it'd save me that lil bit of hassle i have to go thru myself, appreciate the script, just curious tho... anyone know where to find where the albums cache is stored? i kno how to brose thru folders but i much rather have somebody that KNOWS rather than me THINKING i know... lol thanks in advance.

Hi,
I've been looking for a shell search tool for my SE Xperia X10 Android 1.6 phone to search the file system, and this has been the only resource I have found thus far. I have managed to download and copy the scripts to my Android device, but I am unsure on how to execute the .asc scripts on the Android shell.
I was unable to adb push the file to \system\bin. I pushed the file to \data but even mounting the system volume as RW I am unable to mv the scripts to the \system\bin folder.
adb shell
$ su
# mount -o remount,rw /dev/mtdblock3 /system
# mv /data/searh.asc /system/bin
mv /data/searh.asc /system/bin
failed on '/data/searh.asc' - Cross-device link
I tried running the chmod 755 search.asc command anyway, and execute it using ./search.asc, but receive the message:
basename: not found
getopt: not found
[: not found
shift: can't shift that many
Edit: I have now tried this in recovery mode and mounting the /system folder with RW permissions, still no joy.
Could someone please clarify what is required to get these scripts to operate?
I have only dabbled in linux so I am most likely missing something fundamentally obvious here.
Temp-n00b-usr
I managed to find a work around.
I was attempting to locate the Creatouch.apk which was not in /system/app or /data/app. It was infact in /data/app-private. I have manged to pull the .apk for a backup and removed this from the phone now.
I just used the file explorer in Droid Screencast to locate the file by browsing the system.
It would still be handy to be able to search the file system from a PC environment however.

Question about adding stock apps back

I have read and still don't understand how to add back apps like Sprint TV. I have them all saved on my computer I just do not know the commands to get them back into the phone. Do the apps I want to ad back need to be in a certain dir on my computer first. If someone could explain or either point me to a thread that explains this I would really appriciate it.
Seems I found an easy way to add sprints, htc's apps back into the phone once removed. I saved all of them on my computer and used HTC Sync to install the app back. I removed Nscar as a test using root manager, rebooted and it was gone, then opened up HTC synch and added it back. Not sure how to get the odex files back in but it works with apk files.
AFter testing it om HTCfootprints it would not install this. Installed Nscar with no problems.
I am also trying to figure out how to add sprint tv back onto my Hero. I see that people are saying to use adb push, but I can't seem to get it to work. I just rooted with the new fresh rom and everything is great, I just want to add back sprint tv. Any help would be appreciated, thanks
Im a total noob, but I got it the apps back on this way:
Go to the directory where the ADK Tools directory is. Then the following commands:
adb shell
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
chmod 777 /system
chmod 777 /system/app
exit
exit
Then I copied the .apk files that I wanted to push to the tools directory
I am in.
Then did this:
adb push Sprint_TV.apk /system/app
I found it is case sensitive, so make sure you type the filename exactly.
I rebooted my phone and the apps (such as Sprint TV) were back.
I hope this helps, like I said, I spent an hour trying to figure it out, but this worked for me.
I would not recommend doing a chmod 777 on your system or app directory. Not that anything bad will necessarily happen, but it's generally not a good idea to mess with system file permissions when you don't have to.
Your procedure would work fine without those commands at all, in fact. You don't even need to enter the shell; just adb remount and then adb push.
those instructions worked perfectly. Thanks a ton.
I tried this with HtcFootprints. I removed the widget as well. When I added all 4 back in I can see the widget for footprints, but the footprint icon does not show up in the apps section.
Another thing of intrest. When I added Nscar back using HTC Sync, it now shows up as a third party app. It is no longer a system app and I can uninstall it like a market app.
Ok scratch that I did the Footprints again and the Icon is now there Thanks a Ton
I was able to push HtcTwitter.apk and .odex. i cannot get the widget to show up in the add HTC widgets menu. Any ideas?
Well, after trying my hand at update/rom modding with some success... I'm willing to take a shot at making update.zip files to easily flash individual stock apps back onto your phone. That's if there's any interest.

[Q] Blur Camera won't install

Alright so here's my problem: After rooting my phone, I started to play around with a couple of camera apps from different ROMs such as MIUI. Me being an idiot though, deleted the stock Blur camera Apk. Using a system dump of the Atrix, 2 I tried to reinstall it, by placing it in system/app. For some reason. It wouldn't install (show up on my app directory). Anybody have any idea as to why this is happening? Any help would be greatly appreciated, because I really need a camera app.that's supports 1080p video. Thanks in advance!!!

Push the sick app via adb. I read somewhere that with apps such as root explorer it doesn't work for some reason. Hope this helps.

Yes, always use adb to push system apps. Root Explorer will not work.
Sent from my mAtrix2!!
For some reason i get permission denied whenever i try to push through adb. How do i get around this?

To copy anything to /system/app, you need root access.
This will be a 2 step process.
1) push the file from your computer to your phone in a directory that the shell has access to, i.e. /data/local for instance.
2) adb shell into the phone and su, remount /system as rw, then cp the file from /data/local/ to /system/bin
That should elimiate the issue with permission denied, with adb push.

Ok, run EVERYTHING between Code:, and End code from the command line. Just make sure you are in the directory you saved your backup camera.apk to, from your windows command prompt, before you run the commands below.
Code:
adb push BlurCamera.apk /data/local
adb shell
su
mount -o remount, rw /system
cd /data/local
cp BlurCamera.apk /system/app
chown root /system/app/BlurCamera.apk
chgrp root /system/app/BlurCamera.apk
chmod 644 /system/app/BlurCamera.apk
mount -o remount, ro /system
exit
exit
End code
That should hopefully fix it.

Go into file explorer and make sure your system folder is r/w along with both the blurcamera.apk and blurcamera.odex.... then drop both of them into system/app and reboot. Wouldn't think anything else would be interfering?

Im not sure if it really matters on them but long pressing on either of them in file explorer should bring up the permissions and you can change from there. Do the same on your system folder just to double check that the permissions are correct

[Q]Deleting preinstalled apps

I am trying to get rid of lots of bloatware that I don't want in my new unlocked Motorola Atrix hd phone. I have rooted the phone and got terminal emulator and su working. When I read around on the internet, there are posts describing to remount the /system/app for read/write, delete the apk and odex files and the remount again for read only.
My understanding is that root should be able to "rm" those files in "su" mode if you can see them. So why do we have to remount them before deleting and after? What does it do? What happens if I simply "rm" the apk and odex files in /system/app without remounting before or after, I mean if I am able to "rm"?
Thank you.
I believe the logic is that for security reasons the system/app partition is mounted in read-only mode by default. With root privileges, you can mount it as read/write and make changes such as removing apk files. When you're done editing, you should remount the /system/app partition as read-only, restoring it to its default state. If you don't, any process could theoretically make changes to the files in that partition which could damage your OS or apps.
So we remount the partition because we cannot delete them otherwise. That means if we are able to delete them without remounting, it is OK to do so. Correct?
I believe so. But just to be sure, I would strongly advice to make a nandroid backup before you delete any files.

Just use this app free from the Play Store: https://play.google.com/store/apps/details?id=com.jumobile.manager.systemapp
No messing around with Terminal and any commands.
I found out. I could not delete even as su and got a msg that it was read only. That's why we need to remount.
Or you can use Titanium Backup. TB has option to backup system app&data and then remove.
It's safer...
You can also freeze apps with TB. If something goes wrong, you can unfreeze it or do factory reset.
