first time posting to these forums and would like to contribute my findings i was able to gain root on the uscc htc desire in adb using some other guides for the evo 4g unlock. but now i need some help on how to get the modified su in the right place to make this work for the apps. these are the steps i used to gain temporary root.
1) installed android sdk to get adb
2) set up the phone in debug mode
3) downloaded the rageagainstthecage-arm5.bin file(attached)
4) ran this from the sdk folder containing adb.exe
Code:
adb.exe push C:/PATH/TO/FILE/rageagainstthecage-arm5.bin /data/local/tmp
adb.exe shell
cd /data/local/tmp
chown 0755 rageagainstthecage-arm5.bin
./rageagainstthecage-arm5.bin
5) adb shell will exit retype adb.exe shell and now you have root
this is as far as i have got so far now i need to know where to put su which i could not find in /system/xbin
also i am new to the android scene so sorry if this is a bad question, but if i were to flash a recovery image of the gsm desire to my cdma would this work to enter adb in recovery mode or would this brick my phone, i didnt know if the recovery affected that or if that was the rom.
I think you need to put su and Superuser.apk on you sdcard (adb push file /sdcard/)
Then
in your su shell prompt
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cat /sdcard/Superuser.apk > /system/app/Superuser.apk
cat /sdcard/su > /system/bin/su
chmod 06755 /system/bin/su
Please let us know if this works.
I hope this works out!

i found out that this command doesnt actually make the system directory writeable
Code:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
and running it a second time causes the device to reboot.
any sugetions to make it writable, im willing to work on this, but like i said i have no experience with android although i am very familiar linux.
You are aware that while booted into Android the /system is not writeable?
You have to boot into recovery mode to do this.
i am now, i tried the method for the incredible but it seems to not run adb on bootup at least after about 15 tries it didn't work, any suggestions? is there a way to flash the recovery without effecting the radio or rom because there isn't any roms for this phone as of yet, or could you point me in the right direction to start my research on how to write a rom? would it be the same as rolling your own linux distro?
also though this to be worth mentioning there seems to be no su file currently on the phone.
i got some time this morning to dig around in the payload-update.zip files for the incredible and was wondering if i could use this to install su because it looks like it doesn't flash anything (atleast looking at the script it looks like it doesn't, i cant say that for the binary file what does that do?) just wondering if there would be any adverse affects by applying this in recovery.
It might be worth talking to AmonRA, or Koush (I believe he works on Clockwork Mod) for a custom recovery. As for installing superuser, you could try the unrevoked team. (unrevoked.com) I wish I knew more in terms of development to help but I hope this leads you in the right direction.
blitz2190 - Here is a link to Superuser.apk and su. Link
I think you need to put su and Superuser.apk on you sdcard (adb push file /sdcard/)
Then
in your su shell prompt
mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
cat /sdcard/Superuser.apk > /system/app/Superuser.apk
cat /sdcard/su > /system/bin/su
chmod 06755 /system/bin/su
I am very interested to know how this works out. If you need anyone else to help test things let me know. I am not a linux buff, but i can follow commands...

This howto is for those people who are unable to root their Galaxy Tab using any of the automated procedures and do not suffer from CLPS (command-line-phobia-syndrome).
My story: After upgrading my EURO (GSM) Galaxy Tab to JM6 my persistent efforts to root the device using either the z4root or SuperOnClick methods have all been unsuccessful. z4root (v1.3.0) kept crashing at different stages, apparently depending on which and how many background apps were running. With SuperOneClick I never managed to get beyond the "changing permissions" stage.
Since both methods are basically wrappers of the rageagainstthecage application, I tried to perform the rooting procedure manually. Guess what, that worked without any problem and it is pretty easy to do.
The basic steps of the rooting process are:
1) use rageagainstthecage to get a temporary root shell
2) use the temporary root shell to copy three files to the read-only system partition the device
While I find the outlined procedure straightforward, you may not. Anyhow, try this at your own risk.
==== Prerequisites ====
I used Ubuntu 10.10 for this, but it should work on any other distro and on Windows just as well. Whatever OS you use, you need a working adb connection to your Galaxy Tab. Odin or Kies are of no use here.
You need the following binaries
* su
* busybox
* Superuser.apk
* rageagainstthecage
To get the all required files, simply download "SuperOneClickv1.5.5-ShortFuse.zip". That's what I used.
Get it here: http://forum.xda-developers.com/showthread.php?t=803682
Extract the contents of the ZIP, open a command-prompt on your computer and change to the directory where the extracted files are located.
Some advice if shell commands are not your regular cup of tea.
The following instructions show the shell commands. Some are executed on the host computer. Others are executed on the Galaxy Tab. You can differentiate between the two easily: All commands which start with "> " need to be executed in a shell on the host computer. Commands which are prefixed with "$ " are executed on the Galaxy Tab. In both case the ">" and the "$" must not be typed. If you copy+paste from this howto, make sure only to copy the commands and leave out the prompt.
==== Step 1: getting a temporary root shell ====
Copy the rageagainstthecage exploit to a temporary directory.
Code:
> adb push rageagainstthecage /data/local/tmp
263 KB/s (5392 bytes in 0.020s)
Change the file permissions and execute the exploit.
Code:
> adb shell
$ cd /data/local/tmp
$ chmod 777 rageagainstthecage
$ ./rageagainstthecage
[*] CVE-2010-EASY Android local root exploit (C) 2010 by 743C
(other output truncated)
Your shell session will be terminated which will throw you back to the regular command prompt of your host computer.
==== Step 2: restart adb server ====
Now stop and restart the adb server process.
Code:
> adb kill-server
> adb start-server
* daemon not running. starting it now *
* daemon started successfully *
Now reconnect to the Galaxy Tab again. Notice the '#' prompt. This means you have a temporary root shell now. We use this to execute some privileged commands which make the rooting permanent.
==== Step 3: making it permanent ====
First, make the system partition writeable. We need this to be able to copy su, busybox and Superuser.apk to the required locations. Then exit the android shell again.
Code:
> adb shell
# mount -o remount,rw -t rfs /dev/block/stl9 /system
# exit
Now we push busybox and su via adb. Then we install Superuser.apk.
Code:
> adb push busybox /system/bin
> adb push su /system/bin
> adb install Superuser.apk
The final steps are to change the file permissions for su and busybox and then remount the system partition as read-only again.
Code:
> adb shell
# chmod 4755 /system/bin/busybox
# chmod 4755 /system/bin/su
# mount -o remount,ro -t rfs /dev/block/stl9 /system
# exit
That should be all. Try a reboot and some apps which require root, like Titanium Backup. The Superuser.apk should popup a dialog requesting permission.
Hope this helps. Happy rooting.
[update]
This process worked for JMA and JMD as well.
"adb install" Superuser.apk instead of "adb push"
[/update]
It will help me !
Merci ;-)
Fantastic! This is just what I was looking for, thank you! I feel dumb now, because I started a thread of my own right as you posted this. You must just type faster than me
I ran a quick test, and it all looks good. One quick question actually. Why do you mount like this:
Code:
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
When most instructions for the Galaxy Tab have you doing something like this:
Code:
# mount -o remount,rw -t rfs /dev/block/stl9 /system
I'm not saying it is wrong, in fact, it actually worked for me. I'm just curious as to why it works like that? My understanding of mounting partitions and such in Linux is a little bit weak, so I like to indulge my curiousity by bugging fine people like yourself
Anyway, thanks again, this did exactly what I needed it to. Well done, I appreciate it.

Thanks for pointing that out! Actually both the filesystem type and blockdevice name were totally wrong. Apparently the mount command ignores both parameters - at least when they are wrong.
I just verified this as self-punishment for not paying attention:
Code:
# mount
(...)
/dev/block/stl9 /system rfs ro,relatime,vfat,log_off,check=no,gid/uid/rwx,iocharset=utf8 0 0
(...)
/system is mounted read-only to /dev/block/stl9. This is the normal state of things.
Now I remount this without the fstype parameter and using a wrong blockdevice name:
Code:
# mount -o remount,rw /dev/block/xyz /system
# mount
(...)
/dev/block/stl9 /system rfs rw,relatime,vfat,llw,check=no,gid/uid/rwx,iocharset=utf8 0 0
(...)
Surprise, this actually remounts /system in read-write mode. This is why my original howto worked despite using the wrong parameters.
Thanks again. I corrected the HOWTO.
It works for me, but i get now error message: The application calendar save (proces com.android.providers.calendar) is unexpecly stopt. Try again. Forced closing
I had this also with SuperOneClick.
When i want to start the calender in the applications i get it also.
The application wil not run anymore.
How can i resolved this.
Thnx

That is strange. The result of the rooting process is just adding three files to the system partition. I find it hard to believe that this could lead to the problem you describe. However, while experimenting with z4root I had the the effect that there were many rageagainstthecage processes running in the background and the Galaxy Tab slowed down considerably. Perhaps there is something similar going on.
Have you tried rebooting after completing the rooting process?
Try shutting down the Tab completely.After rebooting get a shell on the Tab with "adb shell" and execute "ps". That shows the process list. If that looks normal, I would try a factory reset of the device. Which ROM version are you running?
BlackLevel: Thank you soooooooooo much... I don't get how to hit the Thanks Meter thing, but here is the old fashioned way. I used a MacBook to accomplish your perfect, step by step rooting of an AT&T Galaxy Tab i987. It helps that I'm more comfortable at the command line than with most GUI systems.
I could put this into a bash script, but that could be dangerous. People really need to look at whats happening with 'adb' and have some idea of what adb is for. I did renamed your 'adbmac' to 'adb', then I could cut and paste from your instructions except for adding ./ before the adb... ie. ./adb shell
Again, wonderful work at pulling this all together in one place.
Jeff
This guide worked perfectly! I love a nice quiet clean root and it doesn't get any better than this. You my friend deserve a cookie!
Hi Guys,
I flashed to JMA, rooted it with One Click Root, and everxthing seemdet to be okay, but activating OCLF failed....is there anybody with the same problem?
Jan
Thanks a lot !. It's clean and doesn't need a kies ...
Just a question : after reboot I have to use "su" after "adb shell" to become root.
Is there any way to be root directly after adb shell ?
And thanks again ...

The reason is that "/sbin/adbd" (the adb daemon) is running as the shell user. It would need to run as root user instead. This requires changes to the initial ram disk where adbd the relevant settings are stored.
Dealing with "insufficient permissions for device"
Thanks, this worked for me.
One small thing: running from a Linux sustem (Ubuntu 9.04), to overcome a "insufficient permissions for device" problem, I had to put my Ubuntu terminal session into su mode and restart the ADB server -- cf. groups.google.com /group/android-discuss/browse_thread/thread/f85a795644e65b59?pli=1 :
[[
adb kill-server
sudo adb start-server
adb devices
]]

Thanks for the feedback. On my Ubuntu 10.10 adb runs under my regular user-id (1000) and I do not have to use sudo or run the local adb server as root. That might be due to the way the udev rules are set up. Mine are rather unrestrictive and look like this:
Code:
$ cat /etc/udev/rules.d/51-android.rules
SUBSYSTEMS=="usb", SYSFS{idVendor}=="0bb4", MODE="0666"
SUBSYSTEMS=="usb", SYSFS{idVendor}=="04e8", MODE="0666"
How do yours look like?

Try z4root or SuperOneClick. Both methods are wrappers of the rageagainstthecage exploit and try to automate the manual process outlined here.
This thread should be a sticky. Worked like a charm.
z4root is very simple method..thanks.
thanks to Germany...
I agree, this thread should be sticky. Finaly some sense in android devel section...
Thank you very much for your guide!
I followed all the instructions in your guide, everything seems fine until I try to push the busybox and su to my Galaxy Tab.

I have been trying the z4root and SuperOneClick procedure to root this tab but are all unsuccessful.
I am not sure if it is because of my tab needed a "NAND unlock" (I cannot find any guide about the NAND unlock) because I received this message when I tried to install busybox from the market.
Please help! My tab is carrier locked to Bell Canada, I really wanna to unlock it and root it~
Thanks!

The `no space left on device` message indicates that the /system partition is still read-only. That means the mount command in step 3 was unsuccessful. Did you get any error message when you executed it?
There is already an excellent write-up on how to use SuperOneClick to root your Optimus V.
Unfortunately, you may not have a Windows machine available to run the util, or your PC hates the LG drivers, or you may wish to control how you go about rooting your device.
Hence this short write-up which, obviously, relies on pieces I got from that other write-up.
I. Rooting your device
1. You still need ADB!
2. Download the LG Optimus V Tools package from http://nexus.zteo.com/projects/tools/
3. Unzip it
4. Command-line:
Code:
adb push psneuter /data/local/tmp/
adb push su /data/local/tmp/
adb shell
cd /data/local/tmp
chmod 777 psneuter
chmod 777 su
./psneuter
5. You should be kicked out of the shell
6. Command-line:
Code:
adb shell
mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
cat /data/local/tmp/su > /system/bin/su
mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
(Oh look you are root!)
That's it. You now have permanent root access.
After rebooting your phone, adb should be back to logging you in as a regular user but typing "su" will do the trick.
Note: I realize that the version of SuperUser.apk that comes with SuperOneClick might be re-usable here. I haven't had any success with it but you may.
II. Flashing a new ROM
1. After rooting your device, obviously...
2. Get an image for the ROM you wish to flash...
Currently, my favourite one is a fairly recent version of Zefie's CM7.
You can find it by googling "update-cm-7-04282011-NIGHTLY-thunderc-Xionia-signed.zip" -- I will refer to it, below, as <your_rom_zip_file>
3. Get a minimum Google Apps package for flashing as well.
Here, I would google "gapps-gb-20110325-signed.zip" -- I will refer to it, below, as <your_gapps_zip_file>
3. Command-line:
Code:
adb push flash_recovery /data/local/tmp/
adb push recovery.img /sdcard/
adb push Debug-FormatSYSTEM.zip /sdcard/
adb push <your_rom_zip_file> /sdcard/
adb push <your_gapps_zip_file> /sdcard/
adb shell
su
chmod 777 /data/local/tmp/flash_recovery
/data/local/tmp/flash_recovery /sdcard/recovery.img
reboot recovery
4. In recovery: Flash Debug-FormatSYSTEM.zip
5. In recovery: Wipe cache and dalvik-cache
6. In recovery: Flash <your_rom_zip_file> -- this will take a while
7. Do not reboot!
8. In recovery: Flash <your_gapps_zip_file>
9. Now, reboot.
10. Let your phone think about life for a few minutes
11. Select "Skip" when your phone asks you to create/enter your account info
12. Launch the market; now, enter your main account information
Hey first of all let me tell you that I appreciate this guide. Now my problem is that I am such a noob that I may be doing this wrong.I download the file to my optimus.Then in an explorer I extract it, correct? After that once I put in the first line of command on terminal emulator I get an error that says "adb: permission denied". Please help this guide is my last resort.Whatever I do I can not root through windows.It would be nice if you could explain in more detail every step. Thanks!
help
can u please add a little more detail thank u very much appreciated.
SouthParkFan15:
adb is a tool that you run on your computer; it is available for Windows, Mac OS X and Linux. It is part of the Google SDK.

Could you give me a little more detail regarding what detail you are interested in?

Yes this works with 2.2.1.
On Linux Mint, you can use the package manager or the unzip command in a terminal window.
apk:
Download the SDK at http://developer.android.com/sdk/index.html
Install it, then run "android" and select "Install platform tools"
I finally got adb on my system, but when I type in "adb devices" nothing comes up and when I do any command that involves the phone i get "error:device not found".Yes I have usb debugging on and yes I have all the right drivers installed and yes I have tried rebooting a million times, and no my computer has never recognized my phone the way it should.Let me also point out that though pdanet or droid explorer they can't find my device. Help please I'm desperate!
Oh, my. Sorry to read that.
Problem is, in 2.2.x, the exploits that give you root access rely on ADB itself so you couldn't be more out of luck.
On second thought...this may seem a bit weird but there may be a way. I have to think about it. It would involve using a file manager that agrees to "see" /data/local/tmp, running psneuter from there and keeping our fingers crossed. I'll keep you updated.
Alright thanks cyansmoke! Keep me informed.
I ran all of the steps for rooting and I didn't get one error. It didn't seem to work though. When I launch adb again after rebooting my phone I get permission denied when I try to run su.
Here is the cap from my command line. I have no idea why it didn't take.
C:\phone\LGOptimusVTools>adb shell

It's possible that you have another su in your path that takes precedence.

Hey, do you know if there is a way to upgrade my device to froyo 2.2.2? It's currently 2.2.1 and whenever I go to update system it says something like "Your system is up to date".Incase you have forgotten I have the optimus v that can't establish connections with the computer.So what I could do?I'm thinking that If I do that then maybe it could fix all of my problems (or some of them).Thanks
I don't think that it will help you no.
OK it's taking longer than I thought because my wife's LGV, after I restored it to stock, decided that it would not allow psneuter anymore.
Thus, I will need you to run these commands for me and let me know how that went:
1. First, copy psneuter to the root of your SD Card.
2. Then, download Terminal Emulator from the market
3. Run Terminal Emulator, type:
Code:
cp /sdcard/psneuter /data/local/tmp/
chmod 777 /data/local/tmp/psneuter
/data/local/tmp/psneuter
Now, if we are lucky, you should get kicked out of the terminal app (I know it's weird but there is a claim that it goes through adb(!))
Restart the terminal emulator. If we are double-lucky, your prompt should have changed from '$' to '#'
Fingers crossed. Still surprised to hear that terminal emulator would go through adb. No, let me rephrase that: I am moderately surprised, in fact, considering the limitations put on non-rooted apps.
After I put psneuter on the root of my sdcard.I go to terminal emulator and put in the first code and it says "cp: permission denied".Any suggestions?

Ah, my bad, no "cp" by default.
New instructions:
Code:
cat /sdcard/psneuter > /data/local/tmp/
chmod 777 /data/local/tmp/psneuter
/data/local/tmp/psneuter
After I put in the first code I get an error message saying "cannot create /data/local/tmp/: is a directory".
*facepalm*
Of course I should have written:
Code:
cat /sdcard/psneuter > /data/local/tmp/psneuter
I put in "cat /sdcard/psneuter > /data/local/tmp/psneuter" and I get an error message saying "cannot create /data/local/tmp/psneuter: directory nonexistent".
Any suggestions?

omg no no no no.
if you are talking about trying to use "adb push <name of file> <destination file>"
Then you must use "adb remount" if it fails, you are not on an insecure kernel. Thus your only option is to push to the sdcard then use "adb shell" and navigate to your sd card and use "cp <name of file on sdcard> <destination file location>"
as for the commands, it is NOT what you have posted. it is simply
mount -o rw,remount /system
nothing else is needed. You will seriously mess something up if you try mounting it as yaffs2 considering we use ext4 now. FYI, the above command can only be entered AFTER first entering "adb shell" which gives you a command line on the device to execute commands.

Then you need to use
adb shell mount -o rw,remount /system
thats it. To uninstall apks, use:
adb uninstall <package name>
And you are getting a read only system error because you are trying to create that "file.txt" file onto your "root" directory.
do this:
adb shell cd /data/media/0

Why? What error do you get?
Try to move/copy something into /tmp folder. It should work if you're rooted (your shell shows # instead of $).
If it doesn't work, maybe you have to remount your system as rw (read and write):
Code:
mount -o rw,remount /
after you made your modifications, mount it as ro (read only) again:
Code:
mount -o ro,remount /
If it still doesn't work, we need to see the error you get (copy and paste into this forum) while moving/coping something into /tmp.

Can you verify you entered that command as root?
Please do the following:
Do this on your computer to enter your devices shell
Code:
prompt_PC:~$ adb shell
Code:
prompt:~$ whoami
This should give you either "shell" or "root"
If it says "shell" do:
Code:
prompt:~$ su
prompt:~#
It will show a # instead of $ if you're root.
If you're already root (or you are now root due to su command), do:
Code:
prompt:~# mount -o rw,remount /
Now it should be writeable and you can do your modifications.
After you finished you need to change it to ro (read only) again:
Code:
prompt:~# mount -o ro,remount /
After that you can exit the shell:
Code:
prompt:~# exit
prompt:~$ exit
(first exits su, second exits shell)
I'm sorry if you already did that but I wan't to be sure you did it correctly.
If this procedere doesn't work, please copy and past your input and output into this forum as this might help to understand what's going on/failing etc.

Good luck!
