(Q) Root with Super User

So I'm rooted and downloaded Super User app from market. I have a bunch of root apps but the only app listed in the super user app is Titanium. Any reason why the other rooted apps (Set Cpu, Minfree Manager, etc.) aren't listed?

Have they asked for superuser?

We managed to fix this problem the other night on the irc channel. I didn't post anything because it doesn't seem like many people are using superuser.apk. The problem is that superuser needs to install it's own version of the su program to run properly. The current root method replaces su every reboot. When you lose the su that superuser.apk installs it can't control root access anymore and basically any program can request root without a prompt to you. The fix is to just replace the jk-su file in /system/bin/ with the superuser su. Then every reboot it will just use the one that works with the superuser app. I did this a few days ago and haven't had any problems.
The procedure is as follows (you need to use adb):
Go into the superuser app, go to the "settings" tab and at the very bottom choose to update su (it should change from saying original to something like "su v2.3.1-ef").
Plug the phone into usb and make sure you have USB debugging enabled.
Open a command prompt on the computer and goto your android sdk tools folder to run these commands (IMPORTANT NOTE - Make sure you have the phone screen on and unlocked when you run the su command below because superuser will ask you for permission and you need to click yes. It wont prompt if the screen is off or locked and the adb shell will just sit there waiting for a response. As soon as you click yes on the phone you should get a # in the adb shell):
adb shell
su
mount -t rfs -o remount,rw /dev/block/stl9 /system
cp /system/bin/su /system/bin/jk-su
exit
Now you should just reboot the phone and check that it worked by running any program that needs root access that isn't already listed with superuser. I suggest shootme or wifi tether. tether asks when you start or stop tethering and when you allow a mac address in the access control.

Hmmm cp /system/bin/su /system/bin/jk-su didn't work. I ls /system/bin and don't see jk-su listed just su...

What root did you use? I did mine manually so there may be some differences if you used a one click.
Edit: I just looked at noobnl's one click root and it uses the same script that contains the line:
#copies busybox su
cat /system/bin/jk-su > /sdx/su
so it should definitely be there even if you used his one click.
When you run the command "ls -l /system/bin/jk-su" what do you get?
I get this:
ls -l /system/bin/jk-su
-rwsr-sr-x root root 26264 2010-09-18 06:10 jk-su

Did you get it working? After you updated su through the superuser app then it started working so that is why it asked you for permission when you were in terminal. The problem is that if you reboot without applying the rest of the fix to replace jk-su then you will lose the updated su and it will stop working.

Okay, I did the one click root method that is stickied. Then I did
adb shell
su
after doing su, I initially saw on the phone that unknown user was asking for superuser access. Of course, "unknown user" is me so I granted it. Then I saw the # then I went ahead and did
mount -t rfs -o remount,rw /dev/block/stl9 /system
That worked fine . The line repeated itself which indicates that it worked. When I do
cp /system/bin/su /system/bin/jk-su
it then says cp: not found.
Just to give you a little more info, I just restored my phone with odin to factory defaults, then I updated to the DI07 update. Then I installed the final clockwork mod recovery, then I did the one click root method. Then I installed superuser in the system/app folder.

I'm not sure why cp doesn't work, it just means copy. An alternative to try is to delete jk-su and replace it with the su you updated. Use these commands in place of the cp command:
rm /system/bin/jk-su
cat /system/bin/su > /system/bin/jk-su
Make sure you do this after updating su in the superuser app and without rebooting in between. Let me know if you have any problems.

followed instructions. no errors but i still have no programs asking for permission. i had wifi tether downloaded before and it worked. I downloaded shootme to see if it would ask for permission and it didnt - but it works. neithe one is lited in superuser either.
listed is:
adfree / quickboot / root manager / startup manager ( 3 of them) / super manager / unknown ( spawned right after i followed instrution)
any ideas
uninstall supersuser and reinstalled:
listed apps now:
adfree / busybox installer / root explorer / rootmanager / sufbs / tit backup
again not sure is it is correct. but seems to work "I THINK"

When you go to update su in the superuser app does it say "original" and then change or does it stay updated after you reboot?

what i have:

di07
now for the long and skinny:
i checked. went to superuser and it told me 2.3.1 -ef i then HARD rebooted, came back with no root.and superuser told be original, hard reboot again, still no root. So one more time- third time is a charm - i have root and superuser told me 2.3.1 -ef
thanks again for the help.
i think my phone might not be total stable.. lol
any ideas.
also - i thought about upping root to most recent but unsure if i need to unroot or if i can install over it. your thoughts on this matter!!!!

I doubt you need to update root. The root I used was the original manual method by joeykrim. The one click just automates that method. There is no reason why you should have to reboot multiple times to get this working. You basically just replaced a file with a similar file and the script that was installed when you rooted uses that file to create a new su every time you reboot. Personally, I would wipe to stock with Odin and then use the manual root method to make sure nothing funny is going on with your phone. When you rebooted and the su was "original" you didn't lose root, it just meant that superuser wouldn't work. For now, as long as the 2.3.1 -ef sticks around superuser will work just fine. As an alternative you could try noobnl's newest stuff. Looks like he made it compatible with superuser, so I think that would negate the need to use this type of fix. I'm not sure what he did to add the compatibility but you could probably ask him.

if you flash noobnl's latest kernel, it includes superuser and it works perfectly.

The only issue I see with that is you have to use a DG27 kernel. If you want to use a DI07 kernel you still need to use this fix.

Very true. I didn't think about that.

I have latest Noobls kernel flashed on top of DI07 and this fix did not work.First thing that dint work is i never got SuperUser prompt after i typed su in adb shell,i got su in windows but no prompt on the phone.
To make it short i did the whole procedure from BetterTerminal(now i got su prompt) rebooted and back to same problem.Man,this been bugin me for two days now,sometimes i reboot the phone and i have root permissions then i reboot again and they are gone!
Big question is:is everybody on Epic have same issue or is it just on certain phones,kernels or roms?

[Q] Rooting a rooted Verizon Droid 2 to Gingerbread 4.5.601.A955.Verizon.en.

Does GingerBreak work with this version of Gingerbread 4.5.601.A955.Verizon.en.us? My phone is currently rooted with Z4Root 1.3. Is there an easy way of doing this?
Sam

Use the d3 root method. Works fine.
CM7GB-601

The D3 one click didnt work for me. It tries to reboot and the phone sits at the "Battery OK OK to Program Transfer Mode: USB" mode.
I was rooted before the update. I never used ROMS or anything just rooted for wireless tether and T backup. Not sure how to proceed but Im pretty happy with the update, fixed a bunch of issues for me.
Anyone else not able to root after the ginger ota?

I have the phone in PC Mode (instead of Mass Storage.) I don't know if that makes a difference.
The D3 Method worked great for me and my wife's phone.

Hi everyone,
I have the same question as CSSZiegler, but want to expand on it a little bit...
I have a Droid 2 that was rooted with Z4Root 1.3 several months ago. I also have SetCPU, SuperUser and Titanium Backup. No custom ROMs installed. Big Red just pushed down GB, and of course, I've lost root access. I'd like to regain root again without losing any contacts, Handcent messages, etc. I've read on several forums that the D2 can be rooted just like the D3 with a simple "one-click" operation referenced by quarky42 earlier.
Any opinions or experience with this? I greatly appreciate any and all assistance!

update
My phone downloads the update, I click install now... it reboots and starts the install, then about 35% of the way through, it turns to a triangle with ! Inside. Phone reboots and displays message software update failed. Anyone know where to find a logfile or have any suggestions?

I had the same problem, and I think it is is because we already had Superuser installed. To remove it, from the directory where you downloaded the one click root, open the command window, then type adb shell
when you hit enter, the next line should end with a #
if it's $, run the one click again, then start this over
once you have the # prompt, type
mount -oremount,rw /dev/block/system /system
rm /system/bin/su
rm /system/xbin/su
hitting enter after each line.
After doing this, run the one click, and it should be fine. Worked great for me.

Now I have superuser and can't get rid of it.. .Tried unrooting through z4 and it doesn't work... Tried gingerbreak and the one click root through windows... Neither of those worked...
I either want to root through gingerbread or just get rid of the superuser.

I would SBF back to Froyo with RSDLite and install the OTA GB from phone info updates. After that use the D3 one click root method and you're golden.

That error is usually because your trying to run the program from the wrong directory. Make sure your command line is started from the folder that adb.exe is located in. You can do this by Shift and right mouse button and “open command window here”.

I searched the phone's sd card.. I couldn't find it... do you know where adb.exe is located?

The fact that he said to hold shift and the right mouse button should tell you he's talking about a folder on your computer and not on your SD card.

[q] help needed on 6.2.1

Hi all,
I got my KF few days back, Rooted it, before I could install the android market, got forced update to 6.2.1. 2 days ago saw this new root method using BurritoRoot. Tried rooting it, seems successful, however, now when I arrived at the home page, I cant even open the Superuser app at all. It goes the same for the Root Explorer - prompting:
"Root Explorer has not yet managed to obtain root access. Because of issues with Superuser, this often happens the first time the app is run but is usually fine from then on. Click ok and restart the app and try again. Make sure u respond correctly to the Superuser prompt." Then it comes with a force close.
Seriously I do not know whats wrong with it, now i cant even use the root explorer for me to install Android Market.
Anybody can help me with it?
Million Thanks.

Im using the ROOT INSTALL - Method 1 and I downloaded the file from Rootzwiki, apparently the file is named "com.noshufou.android.su-1.apk". and I used the following commands:
adb root
adb remount
adb push su /system/xbin/su
adb shell chown 0.0 /system/xbin/su
adb shell chmod 06755 /system/xbin/su
adb install com.noshufou.android.su-1.apk
adb reboot
So which means I should use the Superuser -2.apk instead?

Just rooted - unable to backup

Hi all,
Ive spent to weekend reading about rooting and ROMS/Kernels and decided to try it. I used a root kit found here from Mskip (great kit). Ive sucessfully rooted, and then sucessfully installed Smooth Rom 4.3 with the Motley kernel.
Ive downloaded Titanium Backup and Rom Manager. TB worked and I did a backup (which I now cant find) (i have ES File Explorer). I upgraded to Titanium Pro, and now when I open the app is states root was denied. I remember when I first opened TB SuperSu asked me to grant it access. After a reboot I opened SuperSu and stated a Binary update was necessary and performed it.
Now TB pro states root was denied, when I open SuperSu there is nothing there in the apps list, and I dont know how to manually grant TB root access.
Sorry if this is noobish, not sure what to do and I dont want to keep going without a backup.
Edit: When I try to backup in ROM Manager I hit backup, it brings up the notification to name the backup, I hit ok and nothing happens.

That sort of sounds like the SuperSU "su" update might have failed. Can you get root with other apps? (e.g. go in to a terminal emulator and type "su")
Note there is a chicken-and-egg problem if (either) SuperSU/su or Superuser/su fail: they need root themselves to remount /system so that the "su" binary can be updated.
If no apps can get root, then you sort of have "lost root", and the fix is to manually insert the .apk and su binary into /system/app and /system/bin/su (or /system/xbin/su depending on flavor!) either with a flash package in recovery, or manually via the adb shell command line (with custom recovery running).
HTH
PS you should be able to just manually start the recovery and do a backup in the meantime, no? The fact that ROM manager isn't doing anything could either be a lack-of-root problem or something else (a busybox dependency?)

If the SuperSU app (and companion binary) were working correctly, you should have seen one of those "Accept / Deny" pop-up messages coming from the SuperSU app... assuming that you didn't previously grant root access to that terminal emulator app. You didn't mention that happening.... ?
Also, usually the command prompt usually changes from $ to # when you have root, but not always; the explicit way to check would be to (after you have tried the "su" command) to type in "id" and hit return at the prompt - that will tell you explicitly if you are root or not. (That's the letter "i" followed by the letter "d" followed by the return key).
From the way you describe this, it is sounding like you lost root.
I gotta go watch part of the game. In the meantime, perhaps you should at least create a backup manually.
As I said, the simplest fix-up would be to get Superuser.apk/su or SuperSU/su re-installed into /system/app and /system/{x}bin/su (it seems that chainsDD and chainfire use different locations).
There might be floating around someplace a flashable zip file with this stuff in it - to be used for "lightly rooting" a stock ROM after a custom recovery is in place. But things have been in flux recently with both the SuperSU (chainfire) and Superuser (chainsDD) kits because of the JellyBean multi-user support, so the version you might need is important. So you would have to do the research to figure out where.
gotta go - good luck.

If the SuperSU app (and companion binary) were working correctly, you should have seen one of those "Accept / Deny" pop-up messages coming from the SuperSU app... assuming that you didn't previously grant root access to that terminal emulator app. You didn't mention that happening.... ?
Also, usually the command prompt usually changes from $ to # when you have root, but not always; the explicit way to check would be to (after you have tried the "su" command) to type in "id" and hit return at the prompt - that will tell you explicitly if you are root or not. (That's the letter "i" followed by the letter "d" followed by the return key).

Thanks again.
Im watching Superbowl as well. I didnt grant Terminal access. I rebooted into recovery and restored to right after I rooted. SuperSu auto updated through the play store, and stated the binary need updated. I canceled that. TB and ROM manager are showing up in SuperSu. So now Im rebooting into recovery again to after I installed the Smooth Rom/Motley Kernal. I did make a backup of where SuperSu lost root. I now have three backups.
Question on installing the SuperSu apk file. I want to be sure I do it right, if needed. Download the file on my 7. it will go to my download folder. Move it to the system folder and open/run it? what do i do with the current SuperSu folder?
thanks again

I went to my restore point after root and reinstalled 4.3 Smooth ROM Mkernel. I did not take the SuperSu update, (ill wait for the next update) and everything is fine TB an ROM manager working fine, did a backup in both.
Thanks for your help on this.

Dealing with .apk's is not that difficult - drop them into the correct place and reboot.
In Android, apps (.apk files) are stored in one of two places: /system/app or /data/app. It is even possible for two versions of an app to be on the phone - one in /system/app and one in /data/app; that is how upgrades of factory-installed apps happen: the pre-installed app is in /system/app... and never gets deleted (read-only filesystem), whereas update versions get dropped into /data/app. Generally you can just drop an .apk file into either of these locations, wipe the dalvik cache and reboot. During the android boot, these files are compiled into .dex objects in the dalvik-cache, and various version, consistency, rights and permissions are cross-checked.
Think of it this way: when you boot a new ROM for the first time, /data starts out completely empty. Everything needed to support each pre-installed app in /system/app gets created automatically during the android layer start-up.
The "su" native binary is a bit more complicated - it needs to be:
- owned by the user.group root.root
- be executable
- be setuid/setgid
Imagine that you had a copy of these two files on your "/sdcard". If you booted into the custom recovery, you could affect these changes like this:
C:\foo> adb shell
# mount # show what is already mounted
# mount /sdcard # if needed
# mount /system # if needed
# mv /system/app/SuperSU.apk /system/app/SuperSU.apk.old
# cp /sdcard/SuperSU.apk /system/app/SuperSU.apk
# mv /system/xbin/su /system/xbin/su.old
# cp /sdcard/su /system/xbin/su
# chown root.root /system/xbin/su
# chmod 6755 /system/xbin/su
# cd /
# umount /system
# exit
C:\foo>
*
As a practical matter, it is probably easier to just make sure to make a fresh backup if you are about to update the su binary - in case anything goes wrong. It might also be useful to use a root-aware file manager to remount the /system partition in rw mode prior to doing the "update su binary" procedure in the SuperSU app.
Good luck
* note that SuperSU and Superuser apps choose different locations for the su executable file - one uses /system/bin/su and the other /system/xbin/su. There might also be a symlink between these locations. Best policy is probably to examine a known-working installation to determine how to proceed.

Permissions question

This may amount to a n00b question, but here goes: After rooting my Kindle(7.2.3), my GF decided she loved the new look and functionality of it so she wanted me to do the same. Hers was on 7.3, which made the process different, but I was able to do it successfully. I've already installed Market and Google Play, and am now trying to remove the ads by changing Dtcp_apk.apk to Dtcp_apk.bat. However, I keep getting an Operation Failed message. I realize this has to do with changing the permissions, but I can't for the life of me remember how to do it, or where exactly I read it when I rooted my personal Kindle. Any help would be greatly appreciated.

So...
Code:
adb shell su -c "mount -o remount,rw ext4 /system"
adb shell su -c "mv /system/app/dtcp_apk.apk /system/app/dtcp_apk.bak"
...doesn't work?

And now, my n00bness shall shine through. Haha. After I rooted the first Kindle(7.2.3), I only had to change the dtcp_apk.apk file to dtcp_apk.bat and it worked like a charm. The method you are describing, I am not familiar with. Is that something I do within a cmd window? I apologize for not knowing, I just didn't have to do it before...

Yes, those are entered from the command line. The first one remounts the system partition as read/write, allowing changes to be made to that partition. The second one simply renames the file so the system can't find it. The "su -c" part tells the shell to run the commands as the root user, needed on stock systems.

I'm guessing your file manager your using doesn't have full root access I use es file explorer and you go into settings root settings and check them all then you can rename that file you don't have to learn to use adb to do this...

AHA!!!! This was exactly what I did the last time, but couldn't remember this time around. Worked like a charm. Thank you both for the responses and the help. :victory:
