[Q] can i delete /system/xbin folder? - General Questions and Answers

hi,
anyone who has galaxy nexus and haven't modified anything, can you please check and see if you have /system/xbin folder?
i installed some program called busybox by accident and i think it created /system/xbin folder.
so i uninstalled the app but the folder is still there..
so i'm wondering if it was there in the first place..
can i delete the whole folder?
right now i have 3 files in that folder : busybox, dexdump, su.

anyone?

I would not delete the xbin directory, it is a system directory included with the operating system.
"dexdump" is Dalvik disassembler (usefule for developers).
"su" is superuser, so if you delete that you will no longer have root.
"busybox" is a set of useful Linux utilities that are essential when you have root privileges.
So, like I said I would leave it, busybox was not the one who installed that directory.

[Q] installing busybox - pushing files to droid

Hello,
I started experimenting with my Android yesterday when I found out about metamorph which requires rooted phone and busybox..
I managed to root the phone but couldnt install the busybox with the application from the market - it says that busybox was not found..
Then I installed the SDK platform, and wanted to do it with adb
I downloaded busybox ... tar.bz2 file and unrared it into SDK/tools and tried pushing it to my android to /system/local by doing:
adb push /Users/../android/platform-tools/busybox /data/local
but adb pushed the subfolders (children) to the /data/local folder instead of the folder with childen folders itself.
Now I wonder:
1. how to remove all those junk files?
2. am I doing the right thing? should I copy the tar.bz2 without unraring it? what is the right procedure?
is there any easier way to accomplish this?
Thanks for help
One way to get busybox is with titanium backup. Install the app open then menu*problems*Yes, do it.

[Q] Unroot / Return to Stock Recovery for Nexus S 4G (Sprint)

Gang, I've searched and couldn't find. I rooted the Sprint Nexus S 4G and installed CW recovery.
Would some one please be kind enough to point me on how to unroot and return to stock recovery for a return.
Thank you!
Why do you want to return it?

Exchanging for another, I appear to have a defective screen which flickers when phone is shaken.
Yeah this would be good to know, as when you unlock it there is now a big unlocked icon when booting. I could see a sprint rep throwing the phone in my face saying they can't support it.

Use a file manager like Root Explorer or SuperManager (any file manager that can run with root access)
Delete /system/app/Superuser.apk
Delete /system/xbin/su
Delete /system/bin/su
Reboot the phone into the bootloader.
Plug the phone into USB.
Type "fastboot oem lock"
Good to go.
What about the custom CWM recovery?

Oh, my bad. Before deleting root, go to /system/etc and find whatever you renamed the install-recovery.sh file to, and rename it back to install-recovery.sh. Then follow my instructions to delete root, and once you reboot back into the ROM, it will erase ClockworkMod and install the stock recovery. That said, here is a set of updated instructions:
Use a file manager like Root Explorer or SuperManager (any file manager that can run with root access)
Go into /system/etc and find the install-recovery.sh file that you renamed originally, and rename it back to install-recovery.sh. (This will ensure that the stock recovery will be restored on first boot)
If you installed busybox, you'll have to delete it along with all the symlinks that it created.
Delete /system/app/Superuser.apk
Delete /system/xbin/su
Delete /system/bin/su
Reboot the phone into the bootloader.

Did Titanium Backup install busybox into /system/xbin? If so, (I assume you have a nandroid backup just in case), I would delete absolutely everything in that folder except dexdump. If it installed busybox somewhere other than /system/xbin, then we'll cross that bridge when we get there.

I don't believe it to be installed in /system/xbin/ as the only two items showing there are:
dexdump
su

OldBlue, I really appreciate your assistance!
I feel really stupid, there are numerous files inside /system/bin, heck I stopped counting at 40!! I do not see a "BusyBox" file there, what should I look for?

Yeah there will be a bunch. Do you have a terminal emulator installed? If so, go into the terminal emulator:
Type "su" (without quotes)
Type "busybox which busybox" (without quotes)
Tell me what it says.

Oh no wonder! You're all set then. BusyBox is located within Titanium Backup's data folder. You don't need to worry. BusyBox will go away when you uninstall Titanium. So just follow my updated instructions and you're good. Let me know if you have any problems. Make sure you have a nandroid backup of your ROM before you delete root, just in case! You can never be too careful!

Hmmm....try just /etc. Is it in there? Every stock Android build since 2.3.1/GRH78 has had that file in there. It checks the MD5 hash of the current recovery and if it doesn't match up, it flashes the stock one over it. That's really strange.

Nope .... no such file. I even did a search for it with root explorer and it does not come up. If worse come to worse ill pull it from someone's Tom just so I have it on my phone. But I know I did not delete it.

That is very strange indeed. I wonder if Google didn't install it on the Nexus S 4G. Can any other NS4G owners verify if /etc/install-recovery.sh exists on your phone?

Reread that thread. The answer is in there.
Hint: ROM flash packages never put anything in /data
you can preinstall apps to /data/app but it takes update script modding. if you havent figured it out it is a lot easier to add them as system apps in /system/app
@Dani897: I try adding apk to /system/app or /data/app but none are working. When I add apk to /system/app; after the rom flashed and reboot, Samsung kept on flashing forever.

Thanks. How do i check permission? in CWM? In cwm (red) v2.5.1.3 -->Install zip from sdcard --> toggle signature verification-->disable'
In advance, all i see is fix permissions.

no in a terminal emulator or in linux. they get screwy sometimes if you do editing in windows. i cant even seem to get ownership of one of my flash drives on my linux machine after i formatted it with windows.
if you are on a mac you can do it by clicking and choosing "get info" from the context menu apparently but i dont own a mac so i dont know.
i never used it but check out cygwin and do some googling on permissions in terminal/console. it might be best if you are not ready to install a new os. but you can also install ubuntu with the wubi installer inside windows of use a vm with osx or the linux distro of your choice pretty easily. please dont ask for support questions on doing those things.
you can find permissions of files in a directory with ls -l
you can change them with chmod an ususally one of the numbers below but there are others, google is your friend
666 is rw-rw-rw
644 is rw-r--r-
777 is rwxrwxrwx
755 is rwxr-xr-x
644 or 755 are the most likely that they should be.

I'm rooted, trying to install Xposed Framework, how do I delete a file from /system/?

I tried installing it with both Flashify and Magisk, but both methods failed.
When I tried installing it via the included Xposed Installer, it also failed, but gave me the message:
> Error: Xposed_Framework.jar already exists in /system/framework
I'm guessing a previous installation failed, but left the file there.
My next idea is to delete that file from /system/framework and try again, but since it's in an RO directory I don't have permission.
I tried using a terminal emulator to mount the drive in rw mode, and also tried using a root file explorer, but either both methods don't work, or I just couldn't figure it out.
Anyone have an idea of how to remove or rename that file so I can try to install the .zip ?
-Thanks

In the Xposed app you should be able to just run the uninstaller script. If that doesn't work, boot TRWP and delete it from there.

Unfortunately, the uninstaller also fails.
It says it can't remove that file from a read only directory..

Root Explorer....
This app does wonders, it allows you to modify directories in /system and other root folders. You can even change permissions of specific folders/files from read/write/read-only....etc. I've had this app since the earliest of android days and it has been my go to file explorer. Root Explorer of course requires root....but it completely unlocks your phone and allows you to modify any system file that is set to any permission. Of course there are other file explorers that allow you to modify system files, but this is the one that i have the most experience with. You should be able to access the system folder where the Xposed file remains and modify it so it can fix your problem.

This!. I've used it for years. Not muss no fuss. It's not bloated like a certain couple others I know of. It just does what it does and does it well. Manages files. No extra garbage.Give it a try. I'd be surprised if you can't delete it with Root Explorer. If you do try it, go to the folder you want to delete the file from. Once in there, look at the top right of the screen. Somewhere up there It will say MOUNT R/W. Touch that and you should be able to do whatever you want to within that folder.
Do you have the magisk DNSCrypt module installed? If so, thats why you cant modify anything in /system. Not sure why or how it breaks it, but it does. Took me for ever to figure out what was causing it. Now that i removed the module, i can modify anything i want again.
