Deleting/uninstalling apks from /system/app bundled with 3.1 rom

[Guest plasmafire]

I am trying to un-install/delete some of the apps that have been installed as a part of Modaco 3.1 Rom.

But apparently I cannot even when in su mode and root access, with system mounted in rw mode.

I have tried the simple

C:\DevTools\android-sdk-windows\tools>adb remount

remount succeeded


C:\DevTools\android-sdk-windows\tools>adb shell rm /system/app/t

rm: can't remove '/system/app/teeter.apk': Directory not empty

then I tried

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

# rm teeter.apk

rm teeter.apk

rm: can't remove 'teeter.apk': Directory not empty

also

# pm uninstall teeter

pm uninstall teeter

Failure

Please don't tell me to cook another ROM, I would like to be able to delete stuff from my phone without having to wipe everything and start again.

Help please :lol:

I believe you need to be in recovery mode to do this?  You don't say you are not in Recovery, but I just thought I would check.

I wasn't in recovery when I ran the above commands.

but when I am in recovery I see the below. I am sure it is something simple, but this is driving me nuts.

C:\DevTools\android-sdk-windows\tools>adb devices

List of devices attached

HT03ZPL12222	recovery


C:\DevTools\android-sdk-windows\tools>adb remount

remount failed: Invalid argument


C:\DevTools\android-sdk-windows\tools>adb shell

- exec '/system/bin/sh' failed: No such file or directory (2)

C:\DevTools\android-sdk-windows\tools>adb reboot

This rebooted my device, but the other commands don't seem to work.

There's a tutorial on this forum about how to remove apps from the ROM. I have no idea where it is though, sorry!

Make sure you use

adb mount /system

before you try to delete anything, recovery doesn't mount the /system partition unless you tell it to..

[Guest acolwill]

Grab yourself Clockwork recovery (via RomManager) and reboot into recovery using it. From the partitions menu, you are able to mount /system and simply adb shell from your host PC.

cd /system/app

ls -l

rm Twitter.apk

this is not the recovery you need. to make changes to /system partition you have to do the following:

1. connect your desire by USB cable and issue: 'adb reboot recovery', device reboots and shows red trianle/arrow icon

2. change to the directory where you rooted your desire from and run './recovery-linux.sh', screen will show green menu

3. if you get any "error: device not found", issue './adb-linux kill-server' and run ./recovery-linux.sh again until you get green menu

4. adb shell mount /dev/block/mtdblock3 /system

now you may add/remove applications from /system/app

[Guest persko]

These commands are for linux, for windows you need to use

recovery-windows.bat

in place of

recovery-linux.sh

otherwise your instructions are correct.

Thank you kind sir, this was the step I was missing. All is well now, I deleted stuff till my heart was content.
