[Q] ADB Shell Won't Allow me to run as SU

So I'm trying to get into su to run gfree_verify to make sure my permaroot S-off/SIM card unlock/SuperCID was successful, but I'm getting a permission denied error.
What happens is, I type adb shell, then I type su, there's a really long delay, then it tells me Permission Denied. However, when I run the Terminal Emulator from my phone and type in the su command, I get root access just fine.
I used the "official" method that is on the HTC Vision Wiki that is located here. The only thing, however, is that my Android SDK install wasn't installed using any type of installer. I just extracted a zip file and shoved it in a random folder. I did make sure to run the Command Prompt as Administrator before issuing the adb shell command, but I'm still unable to get superuser access through the PC. Trying to use the adb root command gives me an "adbd cannot run as root in production builds" error.
Did I do something incorrectly?

adb kill-server
adb start-server
See if that works. If not, try rebooting your computer.

Does the Superuser app seem to be installed correctly on your phone ?
Do you have the output from gfree ? I wonder if it didn't work correctly with your kernel, it doesn't work with all kernels. What ROM/kernel do you have ?
Which procedure did you use, the one in the Wiki, or one involving dd'ing the eng hboot ?

I rebooted the daemeon, computer, and also the phone. No dice.
The Superuser app is correctly installed. When I ran Adfree and attempted to go into SU in Terminal, I got the usual Allow Superuser access dialog. Both worked without any problems; like I said, I can get root access from the on-the-phone terminal, it's when I attempted to get root access from the adb shell command on my computer where I have problems.
No special ROMs, completely stock post-November OTA update. The only thing I flashed after permarooting was the Clockwork Recovery mod, but adb shell SU wasn't working before this. I initially used some outdated instructions (involving the use of the dd command, and the wpathis.ko or something). I read some more and learned these were out of dated, so I unrooted. I then used the instructions that are on the wiki using gfree to permroot.
gfree_verify works without any problems if I run it from the Terminal Emulator on my phone. Returns the proper values to indicate I'm SIM Unlocked, SuperCID, and S-off. I'm glad it works, but I still don't like the fact I can't use the adb shell. Typing characters on the G2 is a pain in the ass.
I still want to know why I can't enter superuser from the PC adb shell. Am I doing something incorrectly?
Thanks a lot for your help!

Try clearing data for the SuperUser app?

go in your recovery screen from boot, select your mount options, and mount everything lol. Not sure if it'll fix it but everytime I have adb permission issues that seems to fix it and I don't think it could hurt.

This worked perfectly! When I entered su from the command prompt, the SuperUser app popped up on the phone's side and I hit allow. It then let me through.
What exactly was broken though? Why did mounting everything from the Clockwork Recovery menu fix this?

[Q] KFU 0.9.8+ not rooting new KF1 w/ 6.3.2

I have tried every version of KFU from 0.9.5 on up, and have reinstalled the KFU drivers multiple times. FFF & TWRP install fine, but when KFU gets to the part where it removes the root checker I get an error:
Attempt to remove root checker
mv: can't rename 'system/bin/check_rooted': No such file or directory
Please wait...
The Kindle then continues to boot up as normal. It then attempts to install SU:
Installing Superuser.apk
Error: Cound not access the Package Manager. Is the system running?
KFU then states that root has been installed, when in fact it has not. I know that I could simply use TWRP to flash CM 10.1 which would have root, but this Kindle is my wife's (I already have CM on mine). I need root to be able to use Titanium Backup and save all of her app data. Any help resolving this would be appreciated!

I've run into this problem before. This is from attempting to install the .apk before the device is booted far enough for the package manager to be available. This can be easily fixed by pausing the script for an amount of time to ensure the package manager is available before continuing with the rest of the script. You should probably contact the developer about it.
You might be able to just install Superuser.apk using the following command:
Code:
adb shell pm install -r /system/app/Superuser.apk

THANK YOU!!!

Your response made all the sense in the world (duh moment for me, lol)! I took a look at the batch file for KFU, and located the line of code where it calls the sleep function to wait for the Kindle to boot up:
::Wait for Android to finish booting, and install Superuser.apk.
tools\adb wait-for-device
tools\sleep 20
echo. Installing Superuser.apk
tools\adb install -r files\Superuser.apk 2> nul
I changed the 2nd line of the section to call sleep for 60 seconds instead of just 20. Voila! That did the trick. I have sent a message to the developer as well, so that he can make this simple fix. Thanks again for taking the time to help get me on the right path! :highfive:

[Q] Nexus 4 - SU not working anymore but binary present

Hi all,
I come with what is probably a silly question after I did not manage to stumble upon someone with the exact same situation while doing some googling around.
I have a Nexus 4, running the older Android 4.2.2 (did not update as I have some custom patches in there).
My phone has also been rooted for quite a while and working perfectly until recently something broke it (did not manage to find out when I broke it).
I have CWM installed and that is working fine.
I have SuperSu installed, now the latest version.
If I boot my phone into Recovery Mode and then I access it with the shell commands:
a) I mount the sdcard partition
b) I run
$ ./adb shell
~ # /system/xbin/su -
[email protected]:/ #
All works fine.
If I boot my phone normally and I run SuperSU, then I get: "no su binary installed" and the app kicks me out.
If I connect with ADB to it .. then I see that the binary is indeed in /system/xbin/su but trying to run it just doesn't do anything.
The process "freezes" and I don't get a command prompt anymore.
I can cancel it with CTRL+C and try to run it again but still ...nothing happens
This is one point where I am missing the Linux strace which I did not think of having here but would have enabled me to at least see what the SU binary is doing when it is not returning control to the command prompt or at least giving an error
Any idea what might be happening ?
Also..why is "su" working fine when called from the bootloader/CWM and why freezing when calling from the normal running system (aside from that funky error that no su binary is installed).
I tried so far flashing also an older version of SuperSU...same result, then went back to v1.94
Sorry if my problem is stupid but I don't seem to get my way around it...

I solved the first part by myself
Seems Xprivacy suddenly lost my preferences and was not allowing the running of su...
Now from the Terminal App on my Android, I can do: /system/xbin/su - and I get root.
But both SuperSU and SuperUser report that there's no SU binary....
Are they searching for it in some other path ?
I don't get it...
How can the binary not exist but if I run it by hand from the terminal app, everything works perfectly and I get to be root.

The reason you probably did not get responses to this is because you posted it in Galaxy Nexus section and not Nexus 4 forums

[Q] Kindle Fire 8.4.9 Root?

Just got a "factory refurbished" Kindle Fire 8.9 HD for a STEAL (Amazon gave $50 back on the refurb).
Anyway, now that I have it and have been playing with it for a few weeks, I've realized that the current root methods (including Root Many Android) say they have rooted it, but I don't quite have all the SU access. Digging deeper, I've found that I have System Version 8.4.9.
I can get a partial root, but cannot mount the system to RW
Anyone out there working on the Root of Kindle Fire 8.4.9?

I would just downgrade it and flash a custom rom.

Stunts,
I'd love to do that, but one of the issues with the current root is I can't use KFFirstAide to do much of anything. I would like to keep the KF as close to stock as I can, as I have kids and the FreeTime app is nice. I'm mostly looking to get the Google Play store up and working.
I've done a search but don't see anything on how to downgrade the KF from 8.4.9 without having root.
What am I missing?

You don't need root. When you initially power the device on it should briefly be detected as a jem device. Download then drivers in my signature and extract them somewhere. Now open the device manager and plug the kindle in while off, when you see the jem device, right click it and hit update drivers, and tell it to look where you extracted mine. If this is windows 8 you will have to disable driver signature enforcement first. If you can manage to get this step completed the rest is simple, it basically involves this: grab a utility like kindle fire first aid and shift + right click it and hit new command window here. With the kindle off and unplugged type
Code:
fastboot -I 0x1949 getvar product
once it says waiting for device plug the kindle in while it is off, it should enter fastboot, from there you can use kffa to downgrade it.

Would You Like To Wipe Data And Cache (y/n) ?
After this, I wipe data and cache and then didn't finish the registration (so I didn't get "pushed" an update, just in case)
Come back up and I'm still in 8.4.9
I've gone in to dropbox and pulled all the images to my computer. Is there a way to move these and get them properly mounted in adb? I'm a relative n00b but getting a bit more comfy in the adb environment and may be able to do it from there, with a bit of help?
Thanks!

Do not actually use KFFA use this method --> http://forum.xda-developers.com/showthread.php?t=2468988
You only need kffa for adb.exe and fastboot.exe ect.
PS. Be sure NOT to to connect to the Internet after until you have OTA blocked, and if you Like you can manually upgrade to what ever firmware you would like, I went back to v848

Now I'm stuck in the Kindle Fire boot screen - orange. I got through all the flashes without an issue and unplugged on the final reboot per your instructions. I try to adb to it and there are no devices found.
Edit: Whoops. Was using my old shortcut command keys (arrows) and just changed what flashed to system - forgot to flash to the right places. Trying again!

Is your Kindle up and running? I also have a Kindle Fire HD 8.9 and yesterday I downloaded latest update.bin file (8.4.9) from Amazon and updated my Kindle and later rooted it using the manual method described in http://forum.xda-developers.com/showthread.php?t=2069117 thread. It was total success. Just don't miss a single step from that method.
Actually I had my Kindle (ver 8.4.8) rooted before and Google Play installed with the same method but I was having some issues (not because of rooting but because I had been tinkering with the system apps) so decided to update to overcome those glitches. I installed RootKeeper from Google Play and told it to protect my root access during update process but this crap could not. After update I lost my root and now Google Play Store and related services stopped working, as I didn't have root access so couldn't manage to delete their apks from System apps. So I decided to root it again with the same method and I did it, after rooting it again I went to system apps and deleted old apks of Google Play and other related apks. Then I agin installed Google Play using the automatic method mentioned in above thread.
Sorry if this story is irrelevant but I just wanted to share my experience so any one searching for something could find a clue from it. One thing is confirmed here, KFFirstAid can easily install Google Play after 8.4.9 update and the above mentioned manual method can root it successfully. I am not sure about automatic method though.

you have been very usefull! Thx...but, i still can't root with any method
Can i ask you for some help (i've actually the 8.4.9 version) in private?

Already tried this. It works partially only once it is fully done rebooting the kindle fire is running so slowly as to be unworkable for any thing. Also the lock swipe etc looks torn inhalf. At this point i have to use recorvery to get it to respond properly. I need to root or change rom out right (preferably) But the fast boot commands do nothing. Tried getting it to show up as gem device and use the other drivers that are suppose to let me enter fast boot by a fastboot command. It does not seem to work.
So after trying the method in post 9 again i need to recover to factory again. As it is running extremely slow

Stunts what is the best surefire way to downgrade? My previously rooted kindlefire hd 8.9 just got ota updated to 8.4.9. I had disabled ota i thought but it would seem it wasnt. Now i can not reroot it properly. I want to just go with a custom rom and be done with this mess. I do not have a fastboot cable. But it would seem there are ways around that such as the fastboot -i etc etc how ever i tried that and it did not work (including getting the drivers to the jem. I think i may be missing the chance to get the update drivers bit done intime (not sure here). At any rate help!!! heh
Again what i want to do
Downgrade to easiest rom ver to flash from to a custom rom using what ever meathod is the most effective minus fastboot cable. also recommendations on rom to use are very welcome.

This worked for getting root back, but didn't initially work for the Google apps. It looks like Amazon filled the file system /system leaving no room for the apps. Since I don't use Text To Speech, I removed /system/tts/ivona/vox_en_us_salli22i which is 100+MB, freeing plenty of space for Google apps. I saved a copy to /sdcard just in case. I recommend saving a copy of system.img first, since my first attempts at removing files deleted the apk, but didn't free the space and I had to do a restore once.

Full Manual Root - Kindle Fire HD 8.9 System Version 8.4.9 on Ubuntu Linux 14.04
Hi Guys,
If none of the usual methods work, here is a method for rooting Kindle Fire HD 8.9 with the new 8.4.9 system version. It was written for and tested on Linux, but should work on Windows as well.
Requires Linux and "DOS" scripting knowledge - particularly if anything goes wrong. If you are not familiar with linux shell, please do not try!
USE AT YOUR OWN RISK!!!
I was struggling a whole day with rooting my Kindle Fire HD 8.9 with the 8.4.9 stock rom. I use Linux (Ubuntu 14.04) and don't really have access to Windows. I've tried several methods, including several versions of the Bin4ry method, but the result was:
a) nothing happened at the end,
b) the system was hell slow, but did not get the root prompt/access.
Finally I've managed to root with a full manual - no script running - method. It was based on Bin4ry v18.5.1 root: the tools were uploaded to the kindle from the package, and the rooting steps were based on the RunMe.bat (manually entering step-by-step). It requires an installed adb on the linux machine (I have it from an Android SDK install)!
Sources:
http://forum.xda-developers.com/showthread.php?t=2277105 : I've started from here. I recommend to read this before starting the process.
http://forum.xda-developers.com/showthread.php?t=2069117 : "C-2) The next steps are used to Root the Kindle - Alternative Method (Manual Version)"
http://pocketnow.com/2012/10/10/root-without-unlocking : for understanding the exploit
Requirements:
1. Install adb on the linux machine.
2. Download Root MANY ANDROID 32-bit!(Dropbox): https://dl.dropbox.com/u/54456659/Win32.zip and extract.
Rooting:
The steps are based on manually entering the commands of the "1)Normal" method of the RunMe.bat:
1) In a terminal change to the directory where Win32.zip was extracted and enter:
Code:
adb push stuff/busybox /data/local/tmp/.
adb push stuff/su /data/local/tmp/.
adb push stuff/Superuser.apk /data/local/tmp/.
adb shell chmod 755 /data/local/tmp/busybox
2) Restore the fake “backup”. Note: _do not click restore on your Kindle device_! Just enter the command into the command prompt on your PC and press the enter key:
Code:
adb restore fakebackup.ab
3) Run the “exploit”:
Code:
adb shell “while ! ln -s /data/local.prop /data/data/com.android.settings/a/file99; do :; done”
(It will display a lot of "link failed File exists" lines)
4) Now that the “exploit” is running, click restore on your device.
5) Once it finishes, reboot your device. Note: Don’t use your kindle yet, this exploit reboots into emulator mode which will be laggy with a flickering screen (or no display at all). This is normal.
Code:
adb reboot
6) Once rebooted, open a shell:
Code:
adb shell
Check: Once you do step 6, your should have a root shell (your prompt should be #, not $). If it’s not #, start again from step 2.
7) Continue with the steps of the RunMe.bat - now entering the commands in the root shell:
Code:
/data/local/tmp/busybox mount -o remount,rw /system
/data/local/tmp/busybox mv /data/local/tmp/su /system/xbin/su
/data/local/tmp/busybox mv /data/local/tmp/Superuser.apk /system/app/Superuser.apk
/data/local/tmp/busybox cp /data/local/tmp/busybox /system/xbin/busybox
chown 0.0 /system/xbin/su
chmod 06755 /system/xbin/su
chmod 655 /system/app/Superuser.apk
chmod 755 /system/xbin/busybox
rm /data/local.prop
reboot
Done .

The Method described above didn't work for me.
Tried to do it step by step but the exploit part is not working, gives me a syntax error.
Then i used runme.bat and the exploit seems to work (slow reboot, scrambled kindle logo) but root isn't working properly afterwards.
It's kinda half-rooted now, with SuperSU working and displaying "granted root access..."-messages but if i try to install the play store i'm stuck.
ESexplorer is in root mode, mounted system R/W but when i try to move vending.apk to system/app it fails. No root access it seems
Opening SuperSU results in a failed update process....
Any kind of help is deeply appreciated...

This method worked for me! I also got a syntax error the first time arround but I fixed it by splitting this command (adb shell "while ! ln -s /data/local.prop /data/data/com.android.settings/a/file99; do :; done") into 2 separate command 1) adb shell, 2) while ! ln -s /data/local.prop /data/data/com.android.settings/a/file99; do :; done
After taking away the quotes it worked exactly as described!

[Q] Downgrade Issue.

Hello All,
Purchased an Amazon Fire TV from Amazon, it shipped in one day and I have been toying with it for the last few hours. Rooting was easy, as was installing SU, Busybox, Stickmount etc.. However, I am not to the point to where I want to install a custom recovery so I can update to the latest firmware without loosing root. The instructions say I need to downgrade to an earlier firmware in order to do this. My problem is that every time I reboot into recovery it says "Update was not successful" and It boots back to the same version that I started with.
The version I have now is 5.1.1.1.0 fully rooted w/ Busybox. I don't know exactly what I am doing wrong. I have both pushed the update.zip to the AFTV, and I have also put it on a thumb drive. I have tried earlier versions then the one recommended in the guide that I was following. All of this to no avail.
Please help.
Thank you.

Anybody? I was up till little after 3 AM trying to figure this out. Factory reset, re-rooted, nothing seems to work. Has anyone else had this issue?

I had the exact same problem. Try a different firmware download option. I used the "mirror' on AFTVnews.com the first time and had the same fail at the end that you did. I also re installed busybox before I performed the downgrade, so I'm not sure which of the two fixed the problem, but I suspect it was a bad download from the mirror.

Just tried the mirror. That ended in the same result. I am going to try re-installing Busybox again to see if that has any change.

Tried re installing busybox that didn't crack it either.
The exact error is "The System Update was not successful." Your AFTV will restart in a few minutes and should resume normal operation.
Any other ideas I can try?

You need to list exactly what you are doing so we can tell you what you are doing wrong.
I had to do it a couple of times because it didn't work right at first either.

Ok,
Lets start from the top:
Factory Reset
Watch Video
Sign into Amazon Prime
So no to parental controls
Go to developer options and turn it to on so I can use ADB
Connect with ADB
adb install towelroot
go into towelroot and root
adb install supersu
go into supersu and let it update
adb install busybox
go into busybox and install it and let it symlink
adb the command to turn off updates
Then I follow the guide over at aftvnews.com to downgrade
Download the firmware version you wish to install from the software page
Rename the downloaded file to update.zip
Connect to your Fire TV using ADB
(If you don’t know how, follow up to Step 4 Part 2 in our Windows or Mac guide)
Run the command: adb shell
Run the command: su
(If this is the first time you’ve ever run su, a pop-up will appear on the Fire TV, select Grant)
Run the command: chmod 777 /cache
Run the command: chmod 777 /cache/recovery
Note: If
you see a message saying “No such file or directory”, then run the following two commands:
mkdir /cache/recovery
chmod 777 /cache/recovery
Run the command: cd /cache/recovery
Run the command: echo --update_package=/cache/update.zip > command
Run the command: exit
Run the command (yes, again): exit
Run the command: adb push update.zip /cache
(This assumes the update.zip file you renamed in step 2 is in the same directory as adb, otherwise enter the full path to the file like adb push C:\full\path\to\update.zip /cache)
Once the update.zip file has finished transferring to the Fire TV, run the command: adb reboot recovery
At this point your fire TV should restart and begin installing whichever firmware version you selected.

At this point the AFTV restarts and proceeds to install the new firmware about 1/4 way thru it gives the error message and then restarts.
