did you mount /system in rw mode? (it's ro by default)

U dont have write access to system partition in normal use if i read the tutorial right. U have to do it with an update.zip (editing the update script) or with adb both u have to do in recovery menu from modaco i think. Tell me if i am wrong.
Sry for my bad english

@cezarL yes I did
@xtcislove I wish u were wrong..seems like pain.. anyway to do it without a pc?

Damn, you're right. Previously, I had deleted an .apk just to check if it's working, then reinstalled the app right away.
But I just tested now, it looks like after a reboot, the .apk magically reappears, and the application is running as usual

ye..I'm sure it has something to do with the root limitations Paul mentioned in his rooting guide. hope it'll be fixed soon.

Try this: Boot in recovery menu and try the following commands:
adb remount
adb shell rm /system/app/APP.apk
adb shell rm /data/app/APP.apk
where APP.apk is the filename of the apk with the .apk extention, remember case-sensitive!
for example:
adb remount
adb shell rm /system/app/FriendStream.apk
adb shell rm /system/app/FriendStream.odex
take a look before if your app has a odex or try this: (here u need only one command)
adb remount
adb shell rm /system/app/*FriendStream*
Good luck and have fun =)
Edit: Just find a topic =)

I'm trying to do these things in windows at the moment. No issues getting in the recovery with the windows scripts. But when I try to open a ADB Shell after I've gone to recovery I can't really do anything with it and the recovery hangs (not controllable with the track pad).
Anyone can tell me what I'm doing wrong?

You're not doing anything wrong, from what I've seen opening a new adb instance on Windows will kill the server created by the .bat file used for recovery... which means the connection to the device is lost. I haven't looked into it further, but it might be fixeable somehow.

Ah I see, so basicly you undo the patched recovery by opening a new session. It does work properly under Linux then? I run ubuntu on my netbook so It's not a big issue anyway. Thanks for the tip, gonna try under linux now!

I'm having the same problems as:
http://android.modaco.com/content/h...co-com/307401/removing-sys-apps/#entry1256015
I removed a load of HTC widgets but I get strange entries on the widget menu. Anyone know how to get rid of these?
Also, I removed Stocks (.apk and .odex), now I get a force close on 'Accounts & sync'. Anyone know how to remove Stocks properly?
Cheers.

After running the bat file to get into recovery, start a new cmd prompt in windows and use again adb-nilezon for shell commands instead of ordinary adb, and it wont be killed.
This has worked for me atleast

The best, foolproof, failsafe way is to remove them from the rom before installing it... and remember that some services are still required, weather you use them or not.
But, if a system app is already installed you need to remove:
the apk from /system/app
the data from /data/data/appname
the cache from /cache/dalvik-cache
Do not remove Accounts & Sync...

Thanks for the answer.
I guess now is a good time to bake my own ROM!

Well, if you're trying to delete system apps -- you won't be able to delete them from Estrong. I believe Root Explorer will allow you to delete those files, but its a paid app.
I would just advice you to delete whatever apks you don't want from terminal/shell.
Just plug your phone in and open terminal/command prompt and type:
Code:
adb remount
adb shell
cd /system/app
ls -- lists all the apps on your phone, find what you want to remove
rm AppName.apk
rm AppName.odex (not all apks will have odex files), so don't worry if you get an error message
Example:
rm Mail.apk
When you're done, type:
exit
Hope that helps.

Thanks for the answer. I didn't know that I couldn't delete apps with estrong. Though I find it easier to delete apps within android than going into terminal and executing the commands myself. Thanks for the heads up though.

Sure no problem.

I must be an idiot. Everyone keeps saying just type adb shell in a command prompt window. I just get errors saying ADB is not a recognized command. What gives?

It is in the sdk/tools directory.

Got it, I'm in. But now I'm getting read-only file system as I attempt to delete APK's.

Alternately, you can delete apps in one-click with Titanium Backup (which every rooted phone should have, IMO).

adb remount. Got it. Removed a few things I wanted gone after fresh 0.5.3.

[Q] adb remount

Rooted with this method completely stock kernel...
Ok I am new to Samsung but not new to rooting and using adb. I have been searching and maybe I missed something but I can not get adb working properly on my phone and pc. adb remount does not work so I can not push any files over. I have tried all the methods with mount -o rw,remount -t yaffs2 ... etc...
I can get su permissions on the phone but it will not allow me to transfer any files over at all. I even tried to r/w permission with Root Explorer while connected to phone through cmd window and nada. I am not running CWM so I would like to push files over if I can. I have done it the root explorer way of copy and paste its just that way seems so sloppy to me.
Any help would be appreciated since I cant seem to find a method on the web that works for me
Thanks guys

How are you typing the push command? Remember there are 2 sdcards on this phone.
For the internal sdcard
Code:
adb push c:\this\place /sdcard
for the external sdcard
Code:
adb push c:\this\place /sdcard/external_sd
You *shouldn't* have to use mnt/sdcard/external_sd but give it a shot just to be sure.
Doesn't this phone have to be on for ADB to work? I thought I read that. Obviously that seems a bit odd since most have to be in recovery. Or am I wrong about the on part?
Lastly, if you can run 'adb shell' then use the 'cp' or 'mv' commands to get the files on there.
EDIT: Ok, I completely just misread your post. You're trying to write to the /system? Try mount -o remount,rw /system
I don't know why everyone uses the yaffs, mmcblk, and all the other craziness. You still mount /system just with more typing. Let me know if it works.

tried cp and mv still gave me problems moving file. I forget the error message I got. Also I know the proper push commands I used to do it with my Evo all the time. Its just that this phone wont let me mount system. What do you mean be on ADB?

I meant the phone needs to be on (with debugging selected) in order to use ADB and write to it. At least that's what I think I remember seeing. Could be wrong since I haven't used ADB with this phone yet.

no problem now, at first yes but I still cant mount system... driving me nuts since I dont use Clockwork right now I want to push files over... and my software on my pc AndroidCommander says NORoot has been obtained....

I'm probably as new to this phone as you are. Mostly just dealt with HTC. Past this point I have no idea what's going on. I can write to my /system - no problem. Hopefully one of the more seasoned guys will jump in here soon. Sorry I'm not much more of a help.

[Q] Can't delete anything in system/app: Help appreciated!

What's up XDA?
I've been messing around with my Xperia Play and i successfully got it rooted. My next task is to get all the annoying icons and processes that are running in the background deleted to make my phone run like a champ (Also i just like the clean appearance of only the applications that i use in my menu, perhaps OCD).
With that said i have tried a few different ways to get my system folder writeable but nothing seems to work as I am unable to delete anything in that folder.
My questions are the following:
1) How to delete files out of this folder.
2) Is there a way to do this via computer so i don't have to mess around with an explorer application on my phone.
Thanks for the help thus far everyone!

You can delete system apps with adb. Here are some commands you may find useful:
"adb remount" - This will remount /system/ as R/W.
"ls /system/app/" This will list all the .apk's in /system/app/
"rm /system/app/***.apk" - this will delete the specified .apk file.

Thanks for the help.
I was able to get the abd to list out all the files in the apps folder but when i type adb remount it gives me an error saying "remount failed: Operation not permitted"
Any tips?

It's because you do not have insecure adb. Download and install this .apk. after install run it, and your device will reboot. You now have insecure adb and can remount /system/. also once installed you can uninstall app

[HOW-TO] [GSM & CDMA] Root without Unlocking Bootloader via exploit (for 4.0.1/4.0.2)

[HOW-TO] [GSM & CDMA] Root without Unlocking Bootloader via exploit (for 4.0.1/4.0.2)
Edit: This does not works on anything newer than ICL53F (i.e., 4.0.2). It works fine on ITL41D (4.0.1), ITL41F (4.0.1) and ICL53F (4.0.2)
Once you have got root, you can now use segv11's BootUnlocker app to unlock your bootloader without wiping anything. Easy as pie!
Disclaimer: I take no credit for this exploit or the implementation of it (but I will take credit for the step-by step ). Thanks to kendong2 for pointing it out to me here.
So, it looks like zx2c4 has found a local privilege escalation exploit. See source here, and saurik has managed to package it together for Android. See here. Although this may be old news to some, I hadn't seen it before.
So what does this all mean:
If you are running a 2.6.39 kernel (or above), which all Galaxy Nexus' are, you can now root your device without having to unlock your bootloader (and without losing your data).
Moreover, you should now be able to root your device even if your hardware buttons are not working.
Additionally, this allows those who have not received an OTA update and want to apply it without having an unlocked bootloader or root to do so by copying the OTA update to /cache from /sdcard.
Notes:
1) This assumes that you have USB Debugging enable on your device (Settings > Developer Options > Enable USB Debugging) and the drivers for your device installed on your computer. For the drivers, I would recommend you remove all old drivers and install these. If you don't know how to install them, or are having issues, look here.
2) This needs to be done over ADB, as a terminal emulator on-device does not have the appropriate access. If you do not have ADB, I've attached it in the zip. Unzip all files.
3) Some users indicate that, once finished the procedure, they needed to open the Superuser app.
Step-by-step:
1) Download the attached files to your computer and unzip them in the same directory as your adb.exe file;
2) Open a command prompt in the same directory;
3) Copy the files to your device:
adb push mempodroid /data/local/tmp/mempodroid
adb push su /data/local/tmp/su
adb push Superuser.apk /data/local/tmp/Superuser.apk
4) Open a shell: adb shell
5) Change permission on mempodroid to allow it to run: chmod 777 /data/local/tmp/mempodroid
6) Run the exploit: ./data/local/tmp/mempodroid 0xd7f4 0xad4b sh
Note: Once you do step 6, your prompt should change from $ to #. If not, it did not work.
7) Mount the system partition as rw: mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
8) Copy su to /system: cat /data/local/tmp/su > /system/bin/su
9) Change permissions on su: chmod 06755 /system/bin/su
10) Copy Superuser.apk: cat /data/local/tmp/Superuser.apk > /system/app/Superuser.apk
11) Change permissions on Superuser.apk: chmod 0644 /system/app/Superuser.apk
12) Mount the system partition as r/o: mount -o remount,ro -t ext4 /dev/block/mmcblk0p1 /system
13) Rescind root: exit
14) Exit the ADB shell: exit
15) Done. You now should have root without having to unlock your bootloader.

Yikes! This exploit works on any kernel from 2.6.39 and >. This could become a common root method for many devices. Linus Torvalds himself posted the fix commit! Nice work by zx2c4!

You need ics to have a vulnerable kernel version, so given the number of devices which currently have ics officially, I doubt it will be common. I'd also expect Google and vendors to correct this in next release.
Also many custom kernels don't have this flaw as they are at or over 3.0.18 or have patched it. This prevents gaining unnoticed root.

Hmmm I thought 2.6.39 was found in GB builds. This exploit is almost a root fix for the Moto DX 4.5.621 fiasco. Unfortunately the kernel for that build is 2.6.32.9.

Hi, been lurking awhile, registered to clear up somethings.
I did some research while attempting to access the /data/local/ -folder with terminal emulator and I found that it would be impossible to write or to find it while being unrooted. Rooting a phone through using an unrooted access root seems impossible.
Did I miss something or is there any other way to copy mempodroid to the data- folder? I sure would like to keep all my files.

Sure, OK, it worked. But as I'm trying to replicate his instructions, copying mempodroid to data/local/tmp doesn't compute. I tried extracting the files, puting mempodroid in a new folder in ./sdcard/ (which I named Nex), and it still couldn't find it.
Wait, just had an idea. Brb

Hmm. Looks like you may be correct. In GB, we had write access to that directory, but it looks like we don't in ICS. I'll have another look tomorrow and try to figure something out.

OK, this is exactly what I did:
I downloaded the files, extracted them into the ./sdcard folder of my android. I opened the console, wrote exactly as stated. Reaction? Cannot create /data/local/tmp/mempodroid: Permission denied
So, what I'm thinking is this: I tried the cd ./sdcard/mempodroid, found it. So, logically, that should mean that since the permission is dennied, the problem lies not in where I put the mempodroid, but with my authority over my phone. So, here we are again. Could anybody smarter then me clarify?

****, I was hoping I was wrong. I originally thought that the exploit was this. But alas.
Try finding an alternative write route to the /data/local/- folder. That should solve all problems, I guess. Big words, ey? This is for the simpletons like me, who stupidly forgot to bootload.

Might want to expand on the steps.
Like what program to use to copy the file.
How do you change permission.
How do you run the exploit.
How to mount rw.
How to copy su.

I hade my initial problems with that too. But as if this moment it doesn't really matter. Read above posts. Anyhow, to answer your question: you need to download a console emulator
Just search for it in the market. Also the commands go in this console
For example: cat /directory/filename > /newdirectory/samefilename means to copy or move from one place. To change permission you just write that line of code ending with 777 instead of cat and then the filename etc and etc.
I didn't know any of this 'till yesterday, so it is quite understandable.
cheers

I've updated the first post. Give that a go and let me know how it turns out. (The guide may need some minor tweaking, but I am here to help you through it.)
It seems that ADB has rw access to /data/local/tmp but a terminal emulator on-device does not. So for now, you need to be plugged into your computer.
It may be possible to do this with ADB-over-Wi-Fi, but I haven't gotten there yet.
