I have finally taken the plunge and rooted my LG G2.
I followed the directions manually and using FreeGee I THINK I installed TWRP. How do you verify it is installed? I looked all through my apps and can't find it anywhere.
Hope this isn't a stupid question.
Also, Root Browser never asks for SU permissions (and not listed in SuperSU logs), and all the apps I am supposed to be able to safely remove are not shown in the system/apps folder. So confused there as well.
TWRP is a custom recovery, not an app. Download Quick Boot from the play store, and you'll have the option to boot into recovery. To verify you have root, download Terminal Emulator from the play store, and type su at the android:/ $ prompt. After hitting Enter, you should be at a [email protected]:/ # prompt if rooted.
Root. Checker and terminal emulater both show me to have root access.
However root explorer doesn't show any of the apps that are supposed to be safe to remove, and it never asks for su permission like the other root apps do.
Also there is no/ system/apps folder. There is only/ system/app. Are these folders hidden somehow?

Is anyone else in the same boat as me, where they updated prior to instructions reading to move SU to xbin????
I have the SU in my app drawer, I have loaded setcpu and other root programs like barnacle, but I CANNOT for the life of me get the other half of the root apps to work because it says I DO NOT have SU permissions.... like Root Explorer for example.
I wouldn't mind sbf'n it back to 2.1 and then back to 2.2 again at all, just not quite sure what to do.... an ideas?
I was in the same boat as you after upgrading to 2.2 even though I thought I did the xbin step correct, guess not.
Anyways, the only way I fixed it was to completely flash my phone, I didn't mind doing this because it's always nice to start with a fresh install.
This guide was the best for me, simple and includes all necessary links.

Make sure you have busybox installed. There is an appliaction in the market that will download it..

If you didnt move su to xbin, you will HAVE to sbf your x and redo everything to get 2.2 with root. Thats what happened to me.
I did this also...half root and stuff. I used astro to install the su apk off my sd card. I didn't have the ninja guy in my app drawer though. But could run set cpu. Not root explorer. I just again installed the su apk from sd. And it showed up in my app drawer. And I was able to install root explorer. Just my 2's

A fix without adb
To anyone that has run into this problem I have a solution. This is for everyone that missed the step on keeping your root access. If you have su in xbin and still won't work this will work for you.
(Open terminal emulator) type the following:
/system/xbin/su
Then you should see a #
Run "mount -o rw,remount /dev/block/system /system"
Run "mv /system/bin/su /system/bin/su.bak"
Run "cd /system/xbin/"
Run "cp su ../bin/"
Then you should have your root access again!
and one more thing, don't type the word run or put the " " in this code
Same thing happened to me as well, I SBF'd back the first run and did everything EXCEPT the moving su to xbin, and well.... I had to do it all over again, took a bit of time, but now root works again.

So, I'm rooted. S=OFF, I get su access in Terminal, and I have the latest busybox installed in /system/bin. But, after a reboot of the device I can only get R/W access to certain parts of the directory structure - /system is unfortunately not one of them.
Now, here's the weird part: When I start the app Busybox Installer (downloaded from the market), the app searches for busybox installations and tells me I have the latest in /system/bin (this I already know). Once I have started this Installer without doing anything else, I can gain full R/W access to /system.
So, there seems to be some sort of strange busybox issue and how it relates to system R/W access. Is the latest busybox incompatible with this stock ROM?
Root explorer issues
I am also having the same issue I can not get R/W access in the system folder. I have been trying to re-map the Genius button. I am able to remove "bloatware" by using Titanium backup. I definitely have permanent root on the phone, so I am confused by this issue. I have been searching and have not seen other similar complaints. I tried the busybox from the above post but still am not able to R/W access.
You need the latest version of root explorer. Will solve the issue.

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?)

thx for the quick response, however much of that is WAY over my head. I opened terminal emulator and typed su and this is what popped up. 1 [email protected]:/ $
When TB is opened it states error "sorry I could not acquire root privilegdes. this applidation will not work. please verify that your rom is rooted and try again. this attempt was made using the "/system/xbin/su" command.
I dont see busybox in my app drawer

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.

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.
Hi, I'm using Samsung Note 3, i had never root my device. Usually, when i installed some official apps, i still be able to use it. However, when i updated those apps to the latest version recently, my device can no longer use the apps, those apps include some samsung official apps. I had checked those requirements for the apps to work, i had met those requirements like Minimum RAM, android version and etc..
So, i try to checked whether my phone is rooted or not using the "Root Checker" app. It shown as follow:
Root Access: No access
SU: su found [/system/xbin]
UID/GID: n/auid=10378(u0_a378)
gid=10378(u0_a378)
groups=3003(inet),50378(all_a378)
context=u:r:untrusted_app:s0
Unix Utils: n/a
PATH: /sbin
/vendor/bin
/system/sbin
/system/bin
/system/xbin
There is a su file found, but i never root my device.
1. Can i know is it possible for user accidentally rooted a phone when installing some unofficial app? or any other action that caused the existence of su file in my device?
2. I had installed "ES File Explorer", and tried to remove the su file by enabling the Root explorer, but it shown " the feature cannot run on your device", so i had tried to remove the su file by going to the "/", then "system", and "xbin", to remove the su file, but it shown that "su file cannot be deleted". Is there any possible way to remove the su file?
3. Lastly, does anyone know that my device can't run those apps is it whether caused by the "su" file or any other main problem?
Kindly need your help, please. Thank you in advance.
Note: Tested on Latest version of "pokemon go" app, same problem appears, unable to run the app as those official Samsung apps.
I have a nvidia shield tv with full android 6.
adb root and and adb remount is working, so I have root access on shell level.
Also I have /system/xbin/su which goes into root if I do not use "adb root".
But root for apps does not work. No app gets root access, RootChecker says "no".
I installed Superuser.apk but this did not help.
What is missing?
I see that this:
java.io.IOException: Error running exec(). Command: [su] Working Directory: null Environment: null
Caused by: java.io.IOException: Permission denied
I saw that RootChecker tells me "SELinux enforcing", is this the problem?
I do not want to download any ready-made root miracle and flash the whole device.
Since I have adb root, I can adb push everything.
Just flash su.zip and all will be fine.
I don't need SuperSU. I want to root my device i.e. that apps can execute su.
I have /system/xbin/su but it seems that apps cannot use it.
SuperSU is required to give root access to apps, even with full Android. You will need to flash the zip file from TWRP recovery.
How does SuperSU work?
As far as I understand, there is a /system/xbin/su which is called by apps wanting root access.
This su binary then starts the app to verify access. Right?
Not sure, but I think that su is just for adb and maybe system apps.
On my system I have "adb root" access. But apps do not have root access, I do not have supersu or su.
