[Q] Trouble restoring "/system/app"

I (without heeding the warnings) decided it would be a good idea to delete certain apps (including Hero of Sparta, Lets Golf, etc.) once I got my tablet rooted. Luckily, there are two A500's in my household, so I was able to copy the /system/app directory from the other untouched tablet.
Problem is, I can't seem to copy the directory (or any apps from it) into my tablet. I've used both ASTRO and File Manager HD, but in both, the 'paste' command is greyed out. It's as if I don't have the necessary permissions.
So, what's going on?

did you set the Read-Write permission on that directory?

No, thanks for the reminder.
Upon attempting to edit permissions, though, using a terminal emulator, I get an error after typing this:
Code:
su
cd /system/app
chmod 777 /system/app
And the error I get is:
"Unable to chmod /system/app: Read-only file system"

Silly question, but do you have your system rooted?

Yes, I do. Using GingerBreak as I'm still waiting on that 3.1 update

OK, then try a file explorer like Root Explorer and you should be able to set the rights ro R/W and copy your files over.

Root Explorer worked like a charm. I'm suprised File Manager HD doesn't perform those functions. I got a good feeling when I saw that Root Explorer was requesting superuser permission.

Glad to hear that worked. Root Explorer is what I use. Have been for over a year. I think File MAnager HD can also do it, but it is not as straight forward ad Root Explorer. Have fun.

BTW the permission setting 0777 means anyone can access it (or any other application), for the sake of having a better security the permissions should be changed to 445 so only root can access and execute those files (I'm not sure if APKs are considered excutables if they are not the 444 will be the right setting)

[HOWTO] Dalvik2Cache 90MB extra Space for Apps

found this http://forum.xda-developers.com/showthread.php?t=1174160 here in the forum, but cant get it to work on my neo
after a little seaching i found an other script that seems to work on NEO maybe on ARC too
also install-recovery.sh isnt execute on my neo so i put the call into hw_config.sh and it works fine now
howto.
1. push dalvik2cache /system/bin/dalvik2cache
2. adb shell
3. chmod 755 /system/bin/dalvik2cache
4. echo "/system/bin/dalvik2cache" >> /system/etc/hw_config.sh
5. reboot
btw. you need an inscured adb or an insecure kernel like this -> http://forum.xda-developers.com/showthread.php?t=1197263
if you do that, then at your own risk, do not complain when your phone is broken

hi,
i think it should also work without insecure adb and with stock kernel.
but root is needed...
copy the dalvik2cache file to sdcard first
with rootexplorer copy file to system/bin
set permissions
edit the hw_config.sh with editor (rootexplorer)

works great, thanks!

since my kernel supports init.d binaries/scripts u can actually just push it to /etc/init.d/ OR /system/etc/init.d/
it should work... though u may need to verify permissions... chmod 777 is best bet

i placed a scipt in /etc/init.d/ but it isnt execute on startup ...
ps:
the script is startable and permissons should be ok.
if i place the name of that script (/etc/init.d/start.sh) at the end of hw_config.sh then its executet on startup

Hi friends,
I've been trying to do this but I really don't know how to use adb. I have Android SDK installed on my computer, and fastboot, flash...ect. But every time I type "adb remount" then I get the answer is 'adb' is not found (blah blah blah...).
Plus my phone can't boot to recovery. Anyone please tell me where can I find the instruction how to do it? I really want to have more space for my phone and move all installed apps to sd card (I also have my sd card partitioned with ext3 and fat32).
Many thanks in advance.

Have a look at first post in this thread - you have to copy two files

You will have to unlock your phone first and then, using adb, install a custom kernel by fx. DooMLoRD from the link in my signature.

I dont know how to use cmd, can I use Root Explorer?

Anyway to revert it back? Because few apps are missing after it's done.

Hi harfot,
Thank you so much! I have it done now! But I wonder why the free space in my phone is now still the same (184MB - Because I only have a few apps installed).

hey! This sounds like a best solution if you dont want to unlock the bootloader. But I am not too advanced user yet, could you please explain me this one with more details? actually I only need to know
1). which permissions exactly need to be set and
2). what to write inside the hw_config.sh file
Any help appreciated!

bump! no one has any ideas?

Is this code correct
"adb remount
adb push /maps 6.2.0 -mod.apk / system/app"
?
Where should I place the app file?In "platform-tools" folder?
Thank you very much for helping me!

Our on the right path so far.. But the way I've always used adb I kinda dragged everything to the tools folder...I have the library and everything else there...try putting it on our tools folder and see what happens if not check the platform tools.. Just drop the map apk and try it out.

Hmm.. even root explorer.. that's strange you mean mount R/W to R/O in root explorer..
from my end i first did c:\androidsdk then was able to adb push etc...what i could suggest is wait for the signed version.. am on samsung galaxy t989, am at work, i can't really access nothing right now to check with you...i have my mytouch 4g at home...i know you have root access because you said you were able to backup and uninstall using titanium backup.. so i guess you have root access...but try the mount r/w to r/o and see what happens...

You can make the system r/w.
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblk3 /system
i know that's not the exact code but it works just fine for me.

Best way to push modified apks

So I've started modifying my apks to create a custom theme for myself. The question I have, is what is the best way to get them back on my phone.
I pulled them with toolkit, and tried to push them that way, but it didn't seem to work as it said i was missing certificates...
I tried to just push the files into system/apps but that didn't seem to work.
Any suggestions?
Thanks in advance!

Try it the easy way.. Root Explorer copy it in the right place and give the necessary rights.

What do you mean by rights? Are you talking about r/w r/o?

Are you trying to push files with the toolkit? Download the android SDK and push the files with adb. Its much better than root explorer as you'll be able to see changes immediately (except for the framework-res and SystemUI apk's). Also, try pushing to system/app (not system/apps).

I think he means permissions. Like said previously push them with adb as its much simpler, you can also set permissions with adb shell though I cant remember the exact syntax but it's a chmod command.

adb remount
adb push (name of apk) /system/app

lost all permissions after messing with platform.xml

Hello,
I have SM-N9005 variant and recently I updated to the latest android 4.4.2 leaked version with Odin, and then rooted with CF-Auto-Root.
After that, I lost the permission to write to external sdcard.
I searched and found this: http://forum.xda-developers.com/showthread.php?p=49603814
I backed up /system/etc/permissions/platform.xml and then I followed the instructions there.
After restart, a lot of app stopping messages showed and I had no access to file system or network anymore.
I used adb shell to restore the original platform.xml but it didn't helped in any way.
It seems that all mounts and networks are working, but none of the applications has permission to use any of them.
How do I resolve this, without wiping all my data?
Thank you!

You need to set the correct permissions on the .xml after you overwrite it back into the /system Off the top of my head I can't think what they are (just out of bed and got to work so still sleepy!)

I tried 644 and 777 but the problem persists.

rw-r-r which is 644 - read wrong
or chmod 666 -- forgive my lack of memory, it has been a long time since I have used chmod commands, few years since my glFTPD / site modding days.

i dont know if it helps in your situation but did you try the "fix permissions" from a custom recovery like twrp?
there are also scripts you can execute in a terminal, the knoxout script linked in my sig for example has a permission fixer included.

just type sh kn0x0ut.sh to get all commands.
if you dont get this working, you can do it from twrp (i think cwm too)if you have it.
tap on "advanced" and then on "fix permissions".
