Rock & a hard place with Superuser - Fascinate Android Development

Edit: Im stuck. I cannot root my phone because something is wrong with Superuser.apk, and I can't uninstall superuser because I can't get root. And if I try to install Superuser it just fails because it's already in there. So I have no idea what to do now, I need to return this phone to the Verizon store and I can't get the Superuser app off the phone. Any ideas?

http://ip208-100-42-21.static.xda-developers.com/showthread.php?p=6978379
should work. I did this to upgrade from market the version that came with the lag fix from the market.

I couldn't get that to work..

What happens when you adb shell into the device, and do 'su'. If you get a # prompt, you have root.
You don't need Superuser.apk to have root access. You can always run the rage.bin process to get a root shell. From there you should be able to at least rename Superuser.apk to something like Superuser.apk.old.

Yeah, I can type su and get the # prompt. Is this what runs the rage.bin:
adb shell
cd /data/local/tmp
chmod 0755 rage.bin
./rage.bin
?
Sorry, Im new to the ADB process. How would I go about renaming? I wanted to use something like root explorer to find the file and remove or rename it, but I can't get any root apps to work. Obviously because Superuser doesnt function I don't get permission prompt. Root explorer either crashes or says to restart to get the permission prompt.

If you can do "su" and get the # prompt, forget about rage.bin. You have root access, it's just Superuser that's screwed up.
go to your # prompt and do the following
cd /system/app
mv Superuser.apk Superuser.apk.old
See if that gets you any further as far as being able to re-install

I appreciate your help more than you know, really, thanks. I tried that and I get 'failed on 'Superuser.apk' - No such file or directory. Can it be installed anywhere else, like in a temporary directory?
When I try adb install Superuser.apk it starts to then says:
pkg: /data/local/tmp/Superuser.apk
Failure [INSTALL_FAILED_ALREADY_EXISTS]
So I tried what you just mentioned but using the above directory:
#
cd /data/local/tmp
mv Superuser.apk Superuser.apk.old
and it didn't give me any errors, just the #..but when I went and tried to install Superuser again I got the same error as above.

Ok, new update! I remember someone asking me to do ls in adb shell to get a list of what's in there..so, I did that with /system/app and I got a list...at the very bottom of the list was superuser.apk..this whole time i've been messing with Superuser.apk, a capital S. So, I used your mv method on the lower case version, seemed to work..but when I did adb install Superuser.apk I get Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]
Didn't work but I feel Im getting closer

Wow, i just happen to look and the superuser app was no longer showing up in my apps..problem solved. Thanks again for everyone's help in this thread and others.

[GUIDE] Properly Setting Up Root for Your X10

Okay, so I've noticed that this rooting method is a little unconventional. It works through a compromised Fota.pkg which has setuid on /system/bin/sh as root. This is not a very safe, as any application that runs sh will gain root access to your system. Scary... :S Anyway, in order to fix this we need to take a few steps.
It is important that you do these in order, otherwise you may lose root access
Install a proper SU with whitelist
1. Download http://bit.ly/aWgALL
2. Unzip the system folder.
3.
Code:
adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
adb push system/bin/su /sdcard/su
adb push system/app/Superuser.apk /sdcard/Superuser.apk
adb shell dd if=/sdcard/su of=/system/bin/su
adb shell dd if=/sdcard/Superuser.apk of=/system/app/Superuser.apk
adb shell chmod 6777 /system/bin/su
adb shell chmod 644 /system/app/Superuser.apk
4. Reboot your phone.
Fix sh to not setuid to root
1.
Code:
adb shell mount -o remount,rw -t yaffs2 /dev/block/mtdblock2 /system
adb shell chmod 0755 /system/bin/sh
Properly install busybox
1. Here, it's easier to look for the busybox installer app from the market and then install from there. If you did everything correctly, then after you hit install in the busybox app a prompt will come up asking you to allow the app to have root. Hit allow.
You're done!
this might be stupid questions, i know. But where should I unzip the system folder that mentioned to? And where to type those command?

If you followed the root guide you can put it in the step 4 folder.
Then hit windows key + r and in the box type CMD
A console window comes up.
in the console window type cd <path.to.your.step.4.folder>
then go from there.

root in adb
I tried this on the last root (ROOT_F2v2) and I lost root in adb..
I still had regular root
I had to revert it back with "chmod 6777 /system/bin/sh" to get adb do admin task again.. (I use adb regularly)
Does anyone know how to secure sh and still have root in adb?
Regards.

Yes that give me root in adb shell but adb is still running unprivileged.
I believe it's because we can't patch the bootloader yet, so we still have getprop ro.secure 1. :'(
I did a little script to toggle setuid on /system/bin/sh when I'm doing root stuff from adb
Sent from my rooted X10i
I have installed this to protect the system.
The only concern I have is i cannot run for example my cleaning script.
If i type into cmd ;
"adb shell su" it comes up with a # and freezes. If i type in
"adb shell<enter>
su" it works fine. and i can paste all the commands in line by line.
If i do either in a bat or cmd file it crashes. How do i run scripts as su
Here are the answers....

No they were not. The reason is that many of the rooting steps rely on a setuid "sh"

So what? The uid for the shell application launched after invoking "adb shell" is not going to match any of the installed applications anyways. The thing is that Superuser.apk installs a mechanism by which the user (human) can detect when an application is requesting root access. Based upon the nature of the application you may or may not want to grant root access. That is the whole point.

Oh yeah? I just use "su" whenever I want root access... and I didnt have to write any scripts to enable/disable it.

Then you shouldn't be rooting in the first place. Take my advice, lay off the rooting. It definitely doesn't have anything that will be of advantage to you.

easy now, it's a fair question, would be nice to be able to run cleaning scripts on a protected system. no need to be a prick
in answer to the question though, once the batch starts adb shell, it won't continue till that process ends
I did some googling for some comandline tools that might allow sending keystrokes to a process, but nothing easy appeared, looks like your only option is to use a linux friendly notepad to create some shell scripts you can execute from the sdcard. i.e. on device
su
chmod 755 /sdcard/myscript.sh
./sdcard/myscript.sh
easiest way to do scripts on a secured root IMO

Trying to get file access through adb & su

I wanted to backup my K-9 email settings which are supposed to be at
/data/data/com.fsck.k9/
I tried doing adb pull /data/data/com.fsck.k9/ C:\whatever
That gets nothing
I tried going into adb shell and I can move around the folders just fine.
/data/data/com.fsck.k9 has subfolders, but I don't have access to them
(get permission denied)
I tried doing su, and that also got permission denied.
I found a thread from 2009 that talked about getting su.zip from magicandroidapps.com and I did that, put it into /data/local, changed permissions so it is executable, but when I execute it with ./su I get:
su: access granted, courtesy of [www]magicandroidapps.com
su: permission denied
and I still don't have permissions.
I've learned a lot about the android so far, but am at the end of my knowledge. Any suggestions on how to do this?
first time you su from adb the Superuser.apk on your phone is going to want permission... you must click always allow on your phone...
so if you are trying with the phone booted, before typing su make sure your screen is on and then click allow... if it doesnt ask for it, clear your su.apk
if you are trying this from recovery, you have to boot your phone on first and allow adb su permission
by the way, you dont get flamed if you read the rules to posting in this forum...

[Q] Post Root: Root Explorer Question

I finally got my NookColor to sideload apps via ADB. The first thing I did was install Root Explorer and I rebooted the NC.
However, using Root Explorer, I do not have access to the cache or data directories. The response that I get is "Mounted as r/o" and "Your phone doesn't appear to be rooted. ..."
Did I miss something in the process and I'm not really rooted?
Also, I've noticed that the command adb remount gives back an error message as well.
Any thoughts?
Thanks!
See http://forum.xda-developers.com/showthread.php?t=857636
Assuming that you've already install the SuperUser apk
You need to push the su file into /data/local
use the following ADB commands:
Code:
adb push su /data/local/
Then
Code:
adb shell
# cd /system/bin
# mount -o remount,rw /dev/block/mmcblk0p5 /system
# cat /data/local/su > su
# chmod 6755 su
# ls -l su
-rwsr-sr-x root root 26264 2010-12-01 10:27 su
Use the su file from the attachment in the thread below
http://forum.xda-developers.com/showthread.php?t=665974
Thank you, Sapienta.
I noticed the Superuser comes down as a zip and the instructions say to boot into recovery mode and flash ... does that translate to renaming the zip to apk and installing via adb (as I've done with other apps)? Or do I need to figure out how to do the recovery boot/flash?
Ya sorry about that. I should've been more clear. Ignore everything from that page just download the attachment. You need to push the "su" file into /data/local and then chmod it to 6755 per the instructions from the first link I post and you're good to go.
EDIT NVM, I got it
Well, actually, you were quite clear the first time, I had just forgotten about the first link. But now, when I try to install the file (after renaming the zip to apk) via ADB I get an error message that says file does not contain AndroidManifest.xml. But I know the file is there ... I can see it when I view it with 7Zip. So, I guess I'm being dense today, but what am I missing?

Inside of the zip file there should be two files, a file called "su" without an extension and the Superuser.apk.
You'll want to push the su (the file is actually a raw binary) to your NC using the steps provided. You'll also want to install the Superuser.apk after pushing the su binary.
Thank you, antoniouslj. Yesterday I installed SU first and then pushed su but Root Explorer kept erroring out. So just to be sure I'm clear, the steps would be done in this order:
1. Push su -->
adb push su /data/local/
2. Change permissions -->
adb shell
# cd /system/bin
# mount -o remount,rw /dev/block/mmcblk0p5 /system
# cat /data/local/su > su
# chmod 6755 su
# ls -l su
-rwsr-sr-x root root 26264 2010-12-01 10:27 su
3. Install Superuser
Then do I adb Root Explorer or should Root Explorer be installed before I do the steps above?

That's exactly what I did and it worked great for me. I also had Root Explorer installed prior to installing SU.
Still Struggling!
So ... I still can't get this to work. Do I need to install an alternative launcher (like ADW) first and then do this process?

No... what part of the process are you getting stuck on?
I do the three steps like we talked about earlier (and exactly in that order--except I exit out of the shell before I issue the adb install superuser.apk command) and I reboot the Nook. Turn the Nook back on and open Root Explorer, but then RE tells me that there are issues with Superuser and to close RE and restart the RE app. So I do. But it repeats the same process. (I've removed everything so I don't remember the exact language. When I open SU there is no way for me to add an app (that I know of anyway) including looking at the settings. So that's where I'm stuck. And if I can't get root access, then apps like SetCPU and Quickboot won't run successfully.

Grab another version of RE. I'm finding that version matters when trying to sideload apps.
EUREKA!!!
Thanks to everyone for your help! I finally figured it out. Just as I was about to take the last suggestion of finding and downloading another version of RE, I found and downloaded another version of Superuser (version 4). The new SU version extracts from the zip differently but I was finally able to push and modify per the earlier instructions, installed the new SU version, rebooted, started RE, added it to the SU Whitelist and BAM Root Explorer is working just as I expected it to. SetCPU and Quickboot also seems to be working.
Once again, thank you! You were all GREAT!!!

Method to install root for Honeycomb

Check this thread for updated and improved information, many thanks to j4mm3r
http://forum.xda-developers.com/showthread.php?t=953110
Credit goes to NuroSlam for coming up with a working method. This requires a functioning adb connection. Using this version of su is not as secure because it will not activate Superuser for your permission to grant root access. In fact, it can work without Superuser.apk installed at all. Hopefully we will soon have an updated su or maybe the next version of Honeycomb will be prerooted. First download the following files:
1. su http://www.magicandroidapps.com/su.zip
2. Superuser.apk http://bit.ly/su2361ef
3. busybox http://busybox.net/downloads/busybox-1.18.2.tar.bz2
Extract the above files using your favourite program
Using adb, install all three files to /data/local:
adb push su /data/local
adb push Superuser.apk /data/local
adb push busybox /data/local
Use adb remount to open the /system directory
adb remount
Use adb shell to move files
adb shell
cd /data/local
cat Superuser.apk > /system/app/Superuser.apk
cat su > /system/bin/su
cat busybox /system/xbin/busybox
Symlink su and set permissions:
ln -s /system/bin/su /system/xbin/su
chmod 06755 /system/bin/su
Typing su should now work
su
su: access granted, courtesy of www.magicdroidapps.com
Install busybox
exit from adb shell and using a terminal application (i.e Root Explorer or Better Terminal Emulator) on the nook,
su
busybox --install -s /system/xbin
That should do it, works with Root Explorer, Titanium Backup, LCD Density, Quick Boot and SetCPU.
Good Luck
really? That simple? Root was the only reason i haven't jumped on the Honeycomb train. This may change my mind.
I tried this on the 2gb sd image got root. But after I rebooted root was gone.
I noticed su is in /system/bin rather than /system/xbin on the Froyo image. Any reason?

Thanks! I couldn't really follow the part with installing busybox. Was I supose to make the busybox binary? Anyway, I just let titanium backup install busybox for me by clicking the "Problems?" button.
Just tried Root Explorer and it's working great. Nice being able to quickly edit the build.prop file. Upped the dalvik heap size to 64mb and messing with LCD density.

Running busybox from terminal will install all the busybox commands in /system/xbin which should make them available when using adb.
Just a suggestion...
Making a batch file with the command and packing everything in 1 zip makes it a lot easier for most people and reduces the chances of people forgetting a step.
You were right I tried again and now I am rooted after reboot. Thanks

So do I just do these steps to gain root or do I need to partition the sd card first?

Note to the OP, this method isnt exactly quite the same as using the "su" from the SuperUser app would be. This is just a modified "su" binary from the AOSP build which bypasses the check for uid AID_SHELL. Typically, the su shipped with Android only allows root access if invoked via "adb shell".
Now, although this modified binary is quite ok and will get you on the way working with all the Apps that require root access, but it will leave your system unsecure.
You see the guys who developed SuperUser have a hook inside the "su" binary which invokes the SuperUser activity which allows the user to allow/disallow/track other applications' root requests and usage.
So my advice is to be really careful and understand what you are doing if you decide to install this.
I'm gonna try and recompile ChainsDD's SuperUser and see if I can remove its dependency on mktemp.
EDIT: There is no need to push the SuperUser.apk, the modified su has no relation with it and it will work anyways.

Now, although this modified binary is quite ok and will get you on the way working with all the Apps that require root access, but it will leave your system unsecure.
You see the guys who developed SuperUser have a hook inside the "su" binary which invokes the SuperUser activity which allows the user to allow/disallow/track other applications' root requests and usage.
So my advice is to be really careful and understand what you are doing if you decide to install this.
I'm gonna try and recompile ChainsDD's SuperUser and see if I can remove its dependency on mktemp.
EDIT: There is no need to push the SuperUser.apk, the modified su has no relation with it and it will work anyways.

Howard from MagicAndroidApps.com noted this on the original Honeycomb thread. I'll update the OP to make this clear. Thanks.
So once we acquire root, there is nothing to shield apps or commands from performing root without the users knowledge?
Edit: That does sound correct the way i typed it, hope you guys understand what i'm trying to convey

yes, at the stands, its just root access. granted i had my own reasons for this

[Help]Damaged phone, manual root.

Here's my situation...I had 2 rezounds...One perfectly OK, rooted and Titanium backed up, but my kids poured milk into it...yaay. The 2nd rezound which was my wife's seems to have something physically wrong with it where I can't connect to it with fastboot (but adb works ok when the phone is fully booted), which means I can't dev unlock it, or apply most of the root methods out there...
So I decided to try some other things...
I downloaded the Cydia Impactor...
Drop Su didn't work
but,
start telnetd as root on port 22 did work!
so I then went in and remounted /system as RW
and copied su to /system/bin and the Superuser.apk to /bin/apps.
I then performed a echo ro.kernel.qemu=1 >/data/local.prop.
Now when I reboot, I get the root shell if I adb in to my phone...
But, on the screen only the status bar at the top comes up and if I try to swipe down, I get
"Unfortunately, System UI has stopped".
After this, I went into adb shell and noticed the su was gone from /system/bin...So this time I pushed it to /system/xbin, changed to root owner and chmod'd it to 06755..I removed the local.prop since I think that was causing the problem with the launch screen.
After rebooting, the Rezound had deleteed the su again, but the launcher comes up OK.
So I'm thinking, maybe I need to name the su something else...nope that won't work.
I guess for now I can be happy I can get temp root...
1. Run Cydia Impactor and select start telnetd as root on port 22.
2. copy su to /system/xbin and chmod 06755 /system/xbin/su
3. Run Titanium backup, and allow SU access.
works until phone reboot when su is removed by something.
Any ideas for next steps anyone?
Thanks,
Scott
