[Q] su only working from adb on 'rooted' Galaxy Tab 2 - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

I used clockworkmod recovery and the cwm-root-gtab2.zip package to root my Tab 2. su appears to be installed ok, and I can get root permissions by running it from an adb shell:
~ $ adb shell
[email protected]:/ $ id
uid=2000(shell) gid=2000(shell) groups=1003(graphics),1004(input),1007(log),1009(mount),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats)
[email protected]:/ $ su
[email protected]:/ # id
uid=0(root) gid=0(root) groups=1003(graphics),1004(input),1007(log),1009(mount),1011(adb),1015(sdcard_rw),1028(sdcard_r),3001(net_bt_admin),3002(net_bt),3003(inet),3006(net_bw_stats)
[email protected]:/ # ls -la /system/bin/su
-rwsr-sr-x root shell 22364 2008-08-01 12:00 su
[email protected]:/ #
So the su binary is present and has setuid bit set on its permissions. But if I run it from a SSH session, or via a terminal emulator on the Tab itself, I get permission error:
[email protected]:/ $ su
Permission denied
1|[email protected]:/ $
Various root checking apps report similar problems. What am I doing wrong? Other threads suggest steps to recreate the su binary with the correct 6755 permissions, but as far as I can see, everything is already as it should be permissions-wise.
Thanks.

Wrong section. This here is only for Tab 1.

same problem

I cannot find a better match for my situation than this. Any luck? Please link if your post was moved elsewhere.

Well, given the description (even though the OP was for the Gtab 2), I'd try the full path to the su binary.
If "ls -l /system/bin/su shows
-rwsr-sr-x root shell 22364 2008-08-01 12:00 su
then I would try
$ /system/bin/su
and see if it works - there may be another "su" on your $PATH.
If that's not it, then check that your user account has execute permissions to /system and /system/bin

uboot: CRACKED BY BAUWKS
THANKS TO BAUWKS​
Loglud said:
bauwks method uses the flashing_boot.img to his advantage, and since it is not checked by security, effectively he has made an insecure uboot. While this is not an unlocked bootloader, it is a way to get around the security, and enable custom recovery and higher level processes to be run.
I have been looking at this line of code for a long time, and as im sure hkvc and bauwks saw it is a large (but 100% necessary) flaw:
distro/u-boot/board/omap4430sdp/mmc.c: 559 : setenv ("bootcmd", "setenv setbootargs setenv bootargs ${sdbootargs}; run setbootargs; mmcinit 0; fatload mmc 0:1 0x81000000 flashing_boot.img; booti 0x81000000");
Without this line of code, it would be impossible for any one but the factory whom could JTAG flash (but since it is secured, most likely they also have to make a flashing_boot.img).

Enableing adb Connection (eab1)
Install the andriod SDK that is required for your Operating system.
NOTE: This will requries the SDK, and JDK both of which can be downloaded by clicking the links, downloading and installing it.
Run the andriod SDK Manager and Install "Andriod SDK Platform-tools"
[*]Modify your adb_usb.ini file to read such as the following:
Code:
# ANDROID 3RD PARTY USB VENDOR ID LIST -- DO NOT EDIT.
# USE 'android update adb' TO GENERATE.
# 1 USB VENDOR ID PER LINE.
0x2080
This will be in your /home/{username}/.andriod/ folder for mac and linux
This will be in your C:/Users/{username}/.andriod folder for Windows.
ADB is now enabled for your device, however it is not ON your device. YOU MUST DO THIS EVERY TIME YOU WISH TO ADB INTO YOUR DEVICE.
[*]To do this you will need to download any app, and attempt to install it.
You can use this app if you need.
[*]Click on the Package Installer, and then a prompt will pop up asking if you want change the settings to allow 3rd party apps.
*DO NOT ENABLE IF YOU WISH TO ACCESS ADB*
I am working on a way to have it enabled by default.
[*]In the settings page you should see *2* USB Debuggin modes.
[*]Press them both and accept the prompt.
[*]PLUG IN YOUR DEVICE.
Note* You should see the Android Development icon on the bottom of the screen.
ADB will now be able to see your device. How ever you will need to restart the server before it sees it.
Rooting using zergRush (rug2)
This is for the poeople whom have access to adb. You will also need this file. Unzip the file.
Type in the following command (while in the folder with the zergRush Binary):
Code:
adb push ./zergRush /data/local
[*]Once thats installed run this:
Code:
adb shell chmod 777 /data/local/tmp
[*]And lastly:
Code:
adb shell /data/local/zergRush
[*]You are now rooted (only for this reboot)
Installing busyboxy (ibb3)
You will need root and the following busybox file.
Type in the following command while in the location where busy box was downloaded to:
Code:
adb push ./busybox /data/local
[*]Busybox works by calling binaries from a file outside of /system/bin/. We must make this file by issuing the following command:
Code:
adb shell mkdir /data/busybox
[*]Lets make sure we can install busybox without permission probles:
Code:
adb shell chmod 777 /data/local/busybox
[*]Next install busybox in the folder:
Code:
adb shell /data/local/busybox --install
[*]We now need to take the /system/folder, and mount it as a writeable folder:
Code:
adb shell mount -rw -o remount /dev/block/platform/mmci-omap-hs.1/by-name/system /system
[*]Link it into bin:
Code:
adb shell ln -s /data/local/busybox /system/bin/busybox
You now have busybox installed
Permanent root (pr4)
THANKS TO INDIRECT for Files and Scripts
We will need SU and Superuser.apk
First we need to install the Superuser.apk:
Code:
adb wait-for-device install Superuser.apk
adb remount
[*]Next lets go ahead and push the su application up to the /data/local/ folder
Code:
adb push su /data/local/
[*]Next we will need to change the permissions and cp su from the /data/local/ folder to the /system/bin/
Code:
adb shell chmod 4755 /data/local/su;mount -o remount,rw /dev/block/platform/mmci-omap-hs.1/by-name/system /system;busybox cp /data/local/su /system/bin
Installing GApps (eab1)
THANKS TO ANALOG and INDIRECT for Scripts
First things first we need to download the GAPPS. The most reacent one is this one or get the most recent one here.
[*] Unzip and navigate to the most root folder of that package in your shell.
[*]We need to verify that adb is booting into root. To do this we can issue the command:
Code:
adb shell id
If id doesn't return root then you will need to re-zergRush your device
[*]Now it is time for us to export the apps to the directories.
Code:
adb shell mount -o remount,rw /dev/block/platform/mmci-omap-hs.1/by-name/system /system
adb push system/app/CarHomeGoogle.apk /system/app/
adb shell chmod 644 /system/app/CarHomeGoogle.apk

WARNING THIS WILL WIPE YOUR ENTIRE FILESYSTEM!!!
Go into adb shell or terminal emulator.
Issue command:
Code:
echo -n '0000' > /bootloader/BootCnt
Next reboot your device by conventional methods or issue:
Code:
reboot
Your nook will now restart and tell you it is resetting.
You now have a clean slate!
Got some links for howto's on the adb connection/root.
Yeah - if someone has details on how to adb connect and root, it'd be helpful to include links. I've yet to see specifics for either.

CURRENT PROGRESS
adb connection: COMPLETE
adb root: COMPLETE
busybox: COMPLETE
permanent root: IN PROGRESS
bootloader: Locked and Signed
By the bootloader being locked and signed it is very difficult to design anything that will boot besides nook roms. In order to solve this some of the Devs have suggested the following:
kexec: RESEARCHING
2nd init: RESEARCHING
CWM: NOT STARTED
Please PM me or post if you know anything else, and or want to add anything.

hopefully it is cracked soon cause i dont want to buy this if i can't have a full custom rom, all of the verizon motorola phones run roms off of 2nd init and it just isnt the same to be honest. you can never run a full custom rom with second init(well you can but you have to build the rom to fit the kernel) and honestly i want my device to be mine
you should tweet cvpcs or someone who makes and maintains 2nd init roms to get more info on it though
Can't get busybox installed
I'm stuck... I get errors for #3 for busybox... errors like...
Code:
$ adb shell /data/local/busybox --install
busybox: /data/busybox/[: No such file or directory
busybox: /data/busybox/[[: No such file or directory
busybox: /data/busybox/addgroup: No such file or directory
.....
busybox: /data/busybox/yes: No such file or directory
busybox: /data/busybox/zcat: No such file or directory
busybox: /data/busybox/zcip: No such file or directory
So I logged into root via adb shell, set busybox permissions to execute and tried that but same messages?!
Also, adb won't let me 'remount' - (I thought i'd try to copy it direct to /system/bin)?
(I'm running from OSX, if that matters)
EDIT: and of course I'm getting...
Code:
$ adb shell ln -s /data/local/busybox /system/bin/busybox
link failed Read-only file system
$ adb remount
remount failed: Operation not permitted

Sorry it took me so long to get back to you. I have updatd my guide to help you out. First of you will need to make the busybox directory, then change the permissions of the binary file, then run the install. You will then have to mount -rw
Still some glitches installing busybox...

Thanks Loglud, but I still had trouble using adb. It's like I don't have root from adb? I get permission errors on mkdir and remounting etc?
Weird that the 'adb shell mkdir /data/busybox' gave me permission errors?! It did work fine with the interactive adb shell - weird!?
After the initial 'push' command, I could install via:
Code:
mac-osx$ adb shell
$ su root
# cd /data/local
# chmod 755 busybox
# ls -l
-rwxr-xr-x shell shell 1745016 2011-11-21 00:21 busybox
# mount -rw -o remount /dev/block/platform/mmci-omap-hs.1/by-name/system /system
# mkdir ../busybox
# ./busybox --install
Also, is the line:
Code:
# ln -s /data/local/busybox /system/bin/busybox
not supposed to be
Code:
# ln -s /data/busybox /system/bin/busybox
Things went weird on me in the final step, but I did manage to get all the hard linked busybox files to show up in /system/bin eventually, so I'm a happy camper.
EDIT: PS my mount on data is as follows..
Code:
# mount|grep /data
/dev/block/platform/mmci-omap-hs.1/by-name/userdata /data ext4 rw,nosuid,nodev,noatime,errors=panic,barrier=1,data=ordered 0 0
EDIT2:
Hmmm... seems like maybe my /data folder has weird permissions - if so not sure why?...
Code:
# cd /
# ls -l | grep '\<data\>'
drwxrwx--x system system 2011-11-21 18:25 data
# chmod 777 data

ok so whats happening? i modified the guides and i was hopping that would help you. The command is
Code:
# ln -s /data/local/busybox /system/bin/busybox
and as for your permissions it seems as though your root since your in the # shell but, you have to change the permissions on your /system folder not the /data folder the permsisions on the data file should be fine since i think shell is a member of system, so you can put all your data in there.

Yeah, I'm root in the 'adb shell' because I 'su root' but adb commands fail from the Mac shell. I'll reboot my NT and give you the script. My /data permissions get reset when I reboot...
Here you are as it happens
MBAir$ ls busybox

MBAir$ adb push ./busybox /data/local
2881 KB/s (1745016 bytes in 0.591s)
MBAir$ adb shell mkdir /data/busybox
mkdir failed for /data/busybox, Permission denied​
Of course there is no point continuing until I do the following...
MBAir$ adb shell
$ su root
# chmod 777 /data
# exit
$ exit
MBAir$ adb shell mkdir /data/busybox
MBAir$ adb shell chmod 777 /data/local/busybox

MBAir$ adb shell mount -rw -o remount /dev/block/platform/mmci-omap-hs.1/by-name/system /system
mount: Operation not permitted​
To get around the last error, I had to do another 'adb shell', 'su root' and do 'ln' commands manually.
(I actually ran a shell 'for loop' on the tablet, using all files found in /data/busybox as a list and issued ln commands for each against a copy of busybox in /system/bin)

re run zergRush exploit. your adb shell is defaulting to the shell username. by rerunning the zergy you will allow for yourself to use the adb shell as root. make sure you dont run it as the root user though. you are also more then welcome to hop in irc and ask questions.
Any one having difficulty rooting or see anything that needs to be updated?

[ROOT] Mempodroid root - ICS 9.4.2.11+

** This is completely unsupported!!!!!!! **
ALL credit goes to saurik for the root method, Jason A. Donenfeld (zx2c4) for finding the exploit, alpharevx for finding the offsets and initial confirmation on the Transformer Prime and viperboy for finding it and posting it in his thread. I did not research, find, or develop this root method!
Mods, if I've done anything wrong, please feel free to remove this thread.
You will need to know how to use ADB commands, otherwise, use viperMOD PrimeTime!!!!!!!!!!!!!!!!!!!!!!!!.
Downloads:
mempodroid binary
su binary
Root:
adb push mempodroid /data/local
adb push su /data/local
adb shell
chmod 777 /data/local/mempodroid
/data/local/mempodroid 0xd9ec 0xaf47 sh
** You should now be in a remote shell session with root (indicated by #)
mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
** IF you have previously rooted your Prime, run the following two commands. They may throw an error that the file a file was not found.
rm /system/bin/su
rm /system/xbin/su
cat /data/local/su > /system/xbin/su
chown 0.0 /system/xbin/su
chmod 06755 /system/xbin/su
rm /data/local/mempodroid
rm /data/local/su
exit
exit

After your Transformer Prime comes up, install Superuser from android market.
HOPEFULLY everyone has learned their lesson and will also install Voodoo Rootkeeper as well!!!!!!!!!!!!!!!!!!!! R

Changed the mount command - thanks viperboy!
Added steps to possibly resolve issues with previously rooted systems
Changed a few steps to be a little bit easier.
**Jan 24 2012 Edit **
Some people are reporting issues with this method. I suspect this is due to previously having root or other altered files. A method that has worked for some is to update to 9.4.2.11.1 and then following the above procedures. Please note, this firmware release is unofficial and at this time THERE IS NO DOWNGRADE PATH.
i keep getting permission denied after
adb shell /data/local/mempodroid 0xd9ec 0xaf47 mount -o remount,rw '' /system
i missed a chmod step, add it just now.
run:
adb shell chmod 777 /data/local/mempodroid
and then pick up right where you left off.
as i am not root nor superuser .. i don't even get access
/ $ cd data
~ $ ls
ls: can't open '.': Permission denied
after this command
adb shell /data/local/mempodroid 0xd9ec 0xaf47 sh

/mnt/sdcard/Download $ adb push su /data/local
error: device not found

after shell with root, i get the #, but i can't type anything afterwards. do i just repeat the process over?
edit: question was already asked, tried clicking on window, doesn't work.

Try re-installing superuser? When I was rooted before, sometimes superuser wouldn't prompt me for SU on occasion too.

Looks like something went wrong on the first mempodroid command. Go back and start from the begining just in case. Shouldn't hurt anything.

How to get root on chinese Freelander PD80 Shangpin

Hi,
Holding in my hands this Chinese pretty well made and fast thing (maybe just border plastic looks little bit loose).
But in this post I will not tell about quality of this tablet, writing this just for other people who "googled" to solve problems :cyclops:
Device spec:
Freelander PD80 Shangpin
Exynos quadcore
Android 4.0.4
So nothing new here just flow what you need to perform.
Really this article not about rooting actually it's how to get root work here.
I'm using linux so everything below aligned to linux but with some modification you can perform everything under windows.
This flow can be applicable to any device with such problem.
And as usual - Whatever you do with your device, you do that at your own risk.
Description:
1. Executing "su" in connectbot or android terminal emulator return next:
Code:
$ su
su: uid xxxxx not allowed to su
2. By executing "su" from adb shell I'm getting the root rights:
Code:
linux$ ./adb shell
android$ su
android#
Conclusion:
So device is rooted problem just with "wrong" su binary (even busybox inside).
Let's solve it if it's really your problem.
Steps to solve:
1. Download "chainsdd superuser" (site http://androidsu.com/superuser/ direct link http://downloads.noshufou.netdna-cdn.com/superuser/Superuser-3.1.3-arm-signed.zip)
2. extract archive and find inside Superuser.apk and su
3. Put Superuser.apk and su into folder with adb
4. Upload them to android device sdcard by executing from PC:
Code:
# ./adb push ./su_free /sdcard/su_free
Code:
# ./adb push ./Superuser.apk /sdcard/superuser.apk
5. Now we need to move them into system
Launch adb shell:
Code:
$ ./adb shell
$ su
#
6. Make sure that system partition writable (it was my case):
Code:
# mount|grep system
As result you will see:
Code:
/dev/block/mmcblk0p2 /system ext4 rw,relatime,barrier=1,data=ordered 0 0
In our case we don't need that. But if you see "ro" instead of "rw", you need to simply remount it:
Code:
# mount -o remount,rw /system
7. Back up old su binary by executing
Code:
# cp /system/xbin/su /system/xbin/su_ori
8. Copy su binary from sdcard to system
Code:
# cp /sdcard/su /system/xbin/su
Fix permissions:
Code:
# chmod 6755 /system/xbin/su
Check permissions:
Code:
# ls -l /system/xbin/|grep su
You'll see something like this:
Code:
-rwsr-sr-x root root 380532 2013-11-17 01:02 su
-rwsr-sr-x root root 64412 2013-11-17 01:18 su_ori
and link it
Code:
# ln -s /system/xbin/su /system/bin/su
9. Copy superuser.apk to system applications:
Code:
# cp /sdcard/Superuser.apk /system/app/superuser.apk
Fix permissions:
Code:
# chmod 644 /system/app/superuser.apk
Check permissions:
Code:
# ls -l /system/app|grep superuser.apk
You'll see something like this:
Code:
-rw-r--r-- root root 1468798 2013-11-17 01:10 superuser.apk
10. Reboot. And try to execute su from connectbot or android terminal emulator.
You'll be asked about granting permission.
That's all now we can do everything.
Good luck.

[Q] Superuser denied to shell

Hi everyone, I recently installed this ROM here http://forum.xda-developers.com/showthread.php?t=2205516&page=73&nocache=1 (unfortunately I can't post questions on that thread yet). Superuser access works fine from apps and terminal emulator, but if I try to connect from adb with "adb shell su" I get "Permission denied" on my command prompt and a "Superuser denied to shell" toast on the phone.
I can't find a way to change this, apparently the shell user can't su. I tried from the terminal emulator too and here's what happens:
Code:
[email protected]: / $ whoami
u0_a14
[email protected]:/ $ su
[email protected]:/ # whoami
root
[email protected]:/ # su - shell
[email protected]:/ $ whoami
shell
[email protected]:/ $ su
Permission denied
1|[email protected]:/ $
Any help pwetty please?

DL701Q rooted, no apk, (digiland 7") need help backtracking how

Got root, then su binary installed need some help backtracking a few things. If someone is up for it?
I guess the first thing first is. The first time I adb shell'd I got promted with root user: ( does this happen right off the bat for anyone else? I did a few things before this with modstrings and busybox. But, didn't try adb till after)
Code:
adb shell
[email protected]:/ #
Once I noticed I had root on shell I simply found the system mount at /dev/ubui0_0 and I mounted it rw.
Code:
[email protected]:/ # mount -o remount, /dev/ubi0_0
moved the su binary over to the sdcard. wrote it to system/xbin link named to /system/bin. gave permisions.
Code:
adb push su /sdcard/
[email protected]:/ # cat /sdcard/su > /system/xbin/su
[email protected]:/ # ln -s /system/xbin/su
[email protected]:/ # chmod 6755 /system/xbin/su
[email protected]:/ # su
[email protected]:/ # :D
Off I went. I need to update the binary, but as of right now Superuser shows root as 'allow', SuperSU deny (think it old binary).
If you guys are not getting root after adb shell on this device, I think I can backtrack the modstrings and other stuff I did.
I really don't know where this device sits on getting rooted. It seems like some windows programs did it before an update that happened at some point, but not anymore? I don't have access to windows so I don't keep up with those methods.
Thanks! Hope someone can help me out.
