Database Develop

RWSystem and ROSystem

a friend wanted myfaves but I know there is any easier way than to type mount -o rw,remount and the rest I've tried rwsystem and rosystem what am I not doing?
It says rwsystem is not found

you typing it into adb or the terminal?

RWSystem and ROSystem are custom scripts some devs are placing in their /system/bin. Find a build that has them (I think JAC's do) and then push them to the phone with
Code:
adb remount
adb push RWSystem /system/bin
adb push ROSystem /system/bin
adb shell
#cd system/bin
#chmod 0755 RWSystem
#chmod 0755 ROSystem
#exit

oh ok thanks for the help I appreciate it.

when I type it in it says permission denied. I used both ADB and terminal.

you must type "su" first and choose always allow when promted to grant root access.

I did. and I followed all the instructions here it still doesn't work.
do I need to reboot afterwards?

you did make sure to chmod 755 them didnt' you

yep I used adb shell chmod 755.
and then used SU File Browser to chmod 755

[Q]I'm trying to make a little .cmd file to uninstall my apps. need a little help.

Trying to make a little .CMD Files to uninstall my app so I don't have to type everything in again when I do a flash rom.. here is what I have
Code:
pause
@adb kill-server
@adb shell cd /system/app/
@adb shell su*
pause
@adb shell rm /system/app/RemotePVR.apk
@adb shell rm /system/app/tn55-android-blur.apk
@adb shell rm /system/app/FaceRecognition.apk
@adb shell rm /system/app/Layar-samsung.apk
pause
The issue is at the "@adb shell su*" I get an error saying at the super not found.. now when I type the commands in my self it works great.. but in a .bat file or .cmd files it does not work.. what i'm I missing?

Every call to ADB like this is a standalone command.
That is, when you do a
Code:
adb shell cd /system/app/
what happens is that it starts the adb shell, runs the command, and then exits. So when you call su, you lose superuser access when running the next adb shell command, because that shell instance is now gone, kaput, finito.
I also tried to make a script like this, but got stuck. We need to chain commands to ADB, like you can do in *nix with a semi-colon separator between command, like thus:
Code:
command1 ; command2
("&&" in Windows/DOS)
But ADB doesn't seem to support chaining commands.
I guess you have to do a shell script, put it on the phone and run it from there. Or some kind of "adb sushell" command would be nice...

Thanks I was kinda wondering if that was what was happening.. to bad the su command would not stay active.. o well.... maybe someone will come up with something..

Im not at a pc but can u test
adb shell su command
Does tht work ?

you could make a 2nd script which pushes the 1st to the device with "adb push". this script then gets root with "su" and uninstalls/deletes the apps ... btw. you can try using "pm" (packetmanager) which can install/uninstall/reinstall apps. however i don't know if it works with system apps...

Alright here : (eg, say remove launcher)
Code:
adb shell su -c 'mount -o rw,remount /dev/block/mtdblock3 /system'
adb shell su -c 'rm /system/app/Launcher.apk'
adb shell su -c 'rm /system/app/Launcher.odex'
adb shell pm uninstall com.android.launcher
fyi : "SystemApp Remover" on market essentially does the same thing, except it eliminates the need for u to look for the package name ur self.

Hm, that works, but I get a superuser prompt on the phone for every new command (the "app name" is the command line).

sweet that worked. I would get the SystemApp Remover but I can't download paid apps till Google will fix my account. unless there is something like it for free.

Root Frg83(2.2.1) Help please...

Stupid me go back to the stock rom and upgraded to 2.2.1 and lost the root. Ive been trying all day today by following the instruction from this tutorial(http://forum.xda-developers.com/showthread.php?t=736271) but im stuck at the rootshell command. its says permission denied. Can some one please help me..please.. is there any way to root this FRG83, please??

This method does not work anymore.. you have to go a different method..
you can try this method

man thanks alot for your help, but im really a noob.
wud u mind telling me step by step, i know it sounds pretty stupid but pls just guide in the right direction. Much appreciated.

Ouch. I hope you can laugh about this one day. I'm sure you'll have root again.
Have you ever heard the term "curiosity kills the cat".
You knew enough to get root, revert to stock so that you could apply 2.2.1, to discover the hard way that the .1 was mainly, if nothing more than a security patch locking out root. And now need coles notes for above. Sorry, that'll be funny after you have root again.
In the meantime, I hope you find solace in paving the road for future noobs starting new from 2.2.1.
Anyway, the majority of the guide above are sequences while in ADB. You had to use some adb to get
root the first time. Google and do a little research on the subject. You need to polish up as I think the warnings above about "don't do anything until", are warnings to avoid bricking. If this procedure is that risky then your ounce of comprehension is worth a ton of hand holding.

Looks like you don't have the rageagainstthecage binary on your phone.
Doing 'adb shell ls -l /data/local/tmp' on your computer should get you something like this:
Code:
-rwxrwxrwx shell shell 5392 2010-08-25 01:42 rageagainstthecage-arm5.bin
-rwxr-xr-x shell shell 1926944 2010-03-22 20:29 busybox
-rwxrwxrwx shell shell 26248 2010-07-22 10:20 su
-rwxrwxrwx shell shell 27688 2010-07-22 10:19 Superuser.apk
There might be some other files in there; it's these that matter. If you don't see them then do all the 'adb push' and 'adb shell chmod' stuff in the previously linked instructions.

If you can't follow these instrucstions, you should NOT be rooting anyhow, since you obviously have NO IDEA what you are doing.
1) Get rageagainstthecage-arm5.bin

3) Get the Android SDK (ADB)
http://dl.google.com/android/android-sdk_r07-windows.zip
4a) Unzip android SDK (e.g. so that the tools folder is F:\ADB\)
4b) connect Nexus One with with "applications=>development=>USB debug enabled" (and install USB driver if necessary)
5) Unzip/unrar files within RageAgainstTheCage.tgz to F:\ADB\
6) Unzip/unrar files within freenexus.zip to F:\ADB\
7) Open command prompt go to F:\ADB
[7b) Verify that your nexus one is connected and responding - type "adb devices" it should list your N1
8) Now within the command prompt do the following (commands in bold - the rest gives you an indication of the results)

Ok perhaps that what i am doing wrong...
so i download android-sdk_r07-windows.zip & unzip it..to a folder F:\ADB.
So i have to create a new folder named ADB and thne unzip all teh stuff in it??
because before i was unzipping the android-sdk_r07-windows.zip & then the folder named android-sdk_r07-windows & i was upzipping freenexus.zip & RageAgainstTheCage.tgz in the tools folder in the android-sdk_r07-windows folder.
So correct me if im wrong instead of android-sdk_r07-windows folder I have to make a new folder named F:\ADB and then unzinp android-sdk_r07-windows.zip & freenexus.zip & RageAgainstTheCage.tgz in teh F;\ADB folder not in the android-sdk_r07-windows tools folder??
Please advise?>?

Sorry this is so basic ... if you don't understand folder structures, you really SHOULD NOT ROOT!
Do NOT do it! Maybe after using computers for a couple of years you can "upgrade" to rooting your phone.

I can admire how you're so annoyed but I guess i gotta suck it up cus It I who is in need.
LOL! i've been using computers for a while now & I do undrestand the folder structure pretty well why would i think that? Cus I was able to root the phone the first time.
It's just that i find the description so confusing, I use windows, dunno what OS are you on? But when you extract a zip file it creates a default folder of the same name so...
But i really don't think that my question was that hard, which shot you over the moon & piss you off and made you tell me to learn basic computing first.
All i asked was If I am suppose to make a separate folder named ADB & if I sould extract every thing in it rather than the default unzipped folder that windows makes. But I guess If you're so annoyed then i'l leave it for some one else, I am quite sure one of the purpose of this forum is to get and give help. And im pretty sure that there will be someone who can help me or perhaps i'll find a way myself. But anyways thanks alot for your time, you've been nothing but great help. LOL! And I mean it...

[HOWTO] Root Nexus One 2.2.1 FRG83D without OEM unlock

This guide is for people who want root but want to keep their stock rom, not breaking the warranty, unlocking bootloader etc.
A proud ubuntu user, I am writing this in a new thread purely because the manual rageagainstthecage method and SuperOneClick method did not not work for me, see link to my conclusion below if you care
http://forum.xda-developers.com/showpost.php?p=11305312&postcount=2526
What did work however was via adb shell using psneuter and its fairly simple if you follow the following commands.
This guide assumes you know how to get access to the shell via adb, if you dont then search elsewhere for a useful guide
OK lets get to business!
1. Download the attached nexus_one_softroot.tar from the bottom of this post and extract contents to the same folder as adb
2. Open up your terminal, cd to the same folder as adb and the extracted files
3. Enter the following commands:
Code:
sudo ./adb push psneuter /data/local/tmp/psneuter
sudo ./adb push busybox /data/local/tmp/busybox
sudo ./adb push su /data/local/tmp/su
sudo ./adb shell chmod 755 /data/local/tmp/psneuter
sudo ./adb shell chmod 755 /data/local/tmp/busybox
sudo ./adb shell chmod 755 /data/local/tmp/su
sudo ./adb shell
After this you should see only a $ which tells us that we at the android command line with user privileges only, lets continue
Code:
$ cd /data/local/tmp
$ ls
busybox
su
psneuter
$ ./psneuter
property service neutered.
killing adbd. (should restart in a second or two)
You will now be kicked out of android shell, lets go back in
Code:
sudo ./adb shell
After this you should see only a # which tells us that we root baby! If you want to double check issue this command
Code:
# id
uid=0(root) gid=0(root)
Lets continue on. From this point we will install busybox and su which will make root permanent
Code:
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# cd /data/local/tmp
# ./busybox cp busybox /system/bin
# chmod 4755 /system/bin/busybox
# busybox cp su /system/bin
# chmod 4755 /system/bin/su
# exit
For some reason I sometimes have to enter exit twice to leave the android shell. Again, re-access the android shell
Code:
sudo ./adb shell
Now in the android shell we can finish up
Code:
# su
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
# exit
# exit
Lastly we must install Superuser, and I did this from the android market so I knew its the latest version, its simple to get, less command input etc.
Now you have root! I hope this was simple enough to follow, I have not really written a guide before but from lots of searching I just could not find a solution for my Nexus One 2.2.1 FRG83D, especially any guide that uses psneuter.
Anyway, glad to contribute
EDIT - also, being new to starting threads, this may not quite be in the right section of the forum, sorry if thats the case mods

I believe this is due to a change in the kernel as it is upgraded into gingerbread, the input/output controls have changed, leaving psneuter out of date with the current kernel.
However if an exploit is found with the kernel used in 2.3.3, you can use it in place of psneuter with the above method.

[Q] Help rooting

Hi Android Gurus,
I am new to android and rooting. I tried to follow the steps available in the xda forums to root my kindle fire HD 7". But instead of just executing the scripts, I chose to read the scripts and manually execute them comand by comand so I could learn. In the process I did what seems to be like a terrible mistake by setting the wrong permissions on /system/xbin/su like below instead of 06755
-rwxr-xr-x root root 380532 2013-01-03 00:24 su
Basically I cannot su anymore, hence I cannot mount the /system rw to modify su's permissions (sounds like a chicken-and-egg situation here).
I badly need help and appereciate if some of you can provide a way.
Thanks.

Hi Android Gurus,
I am new to android and rooting. I tried to follow the steps available in the xda forums to root my kindle fire HD 7". But instead of just executing the scripts, I chose to read the scripts and manually execute them comand by comand so I could learn. In the process I did what seems to be like a terrible mistake by setting the wrong permissions on /system/xbin/su like below instead of 06755
-rwxr-xr-x root root 380532 2013-01-03 00:24 su

So you can not perform:
adb shell chown 0.0 /system/xbin/su chmod 06755 /system/xbin/su
What happens when you attempt to run these commands? If not, your real option is to go to our thread
noted below and use Root MANY ANDROID! to fix it.

I get this. The problem is that I now have a read-only /system so I couldn't change owner/permissions.
[email protected]:/ $ chown 0.0 /system/xbin/su
Unable to chmod /system/xbin/su: Read-only file system
10|[email protected]:/ $
I also tried to copy su binary again to /data/local/tmp again to see if I can recreate su ownership/permission but I'm unable to do that as well
[email protected]:/data/local/tmp $ pwd
/data/local/tmp
[email protected]:/data/local/tmp $ ls -l
-rwxr-xr-x shell shell 1085140 2012-08-09 13:42 busybox
-rwxrwxrwx shell shell 91980 2008-02-28 22:33 su
[email protected]:/data/local/tmp $ chown 0.0 /data/local/tmp/su
Unable to chmod /data/local/tmp/su: Operation not permitted
Will redoing "Root MANY ANDROID!" solve this problem?

xdajunior,
Yes, both Root MANY ANDROID! and Qemu will solve your issues. Then you can take a peek
inside the batch files to see how they get the job done. Since you are in a pickle, you
really need these utilities. Be sure you download these utilities from our site, there are
minor bugs in the original versions. If you have any questions, let me know, I love to
teach people and would be willing to offer you some free phone support. This time
would be spent teaching you some of the aspects of the Kindle and Android. I
will be around all day tomorrow, from 11am to 10pm PST GMT -8. Sorry for the
delayed repose I was on an emergency call most of the afternoon.
