it has already been said multiple time su has to be chmod 4755
but is as also to have these credentials: root.shell
mine was root.root so as a shell user you get an "access denied."
so a chmod root.shell /system/bin helps
after you need to re-chmod 4755 has it's loosing +s.
Also, if you pushed su to /data/local/bin, do this:
rm /data/local/bin/su
Because normal shell looks in /data/local/bin BEFORE /system/bin. It's part of the path.
thanx
my terminal now works as root
I've removed "m7" and "su" from /data/local/bin after root thanks to coolbits.
This guide is for people who want root but want to keep their stock rom, not breaking the warranty, unlocking bootloader etc.
A proud ubuntu user, I am writing this in a new thread purely because the manual rageagainstthecage method and SuperOneClick method did not not work for me, see link to my conclusion below if you care
http://forum.xda-developers.com/showpost.php?p=11305312&postcount=2526
What did work however was via adb shell using psneuter and its fairly simple if you follow the following commands.
This guide assumes you know how to get access to the shell via adb, if you dont then search elsewhere for a useful guide
OK lets get to business!
1. Download the attached nexus_one_softroot.tar from the bottom of this post and extract contents to the same folder as adb
2. Open up your terminal, cd to the same folder as adb and the extracted files
3. Enter the following commands:
Code:
sudo ./adb push psneuter /data/local/tmp/psneuter
sudo ./adb push busybox /data/local/tmp/busybox
sudo ./adb push su /data/local/tmp/su
sudo ./adb shell chmod 755 /data/local/tmp/psneuter
sudo ./adb shell chmod 755 /data/local/tmp/busybox
sudo ./adb shell chmod 755 /data/local/tmp/su
sudo ./adb shell
After this you should see only a $ which tells us that we at the android command line with user privileges only, lets continue
Code:
$ cd /data/local/tmp
$ ls
busybox
su
psneuter
$ ./psneuter
property service neutered.
killing adbd. (should restart in a second or two)
You will now be kicked out of android shell, lets go back in
Code:
sudo ./adb shell
After this you should see only a # which tells us that we root baby! If you want to double check issue this command
Code:
# id
uid=0(root) gid=0(root)
Lets continue on. From this point we will install busybox and su which will make root permanent
Code:
# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
# cd /data/local/tmp
# ./busybox cp busybox /system/bin
# chmod 4755 /system/bin/busybox
# busybox cp su /system/bin
# chmod 4755 /system/bin/su
# exit
For some reason I sometimes have to enter exit twice to leave the android shell. Again, re-access the android shell
Code:
sudo ./adb shell
Now in the android shell we can finish up
Code:
# su
# mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system
# exit
# exit
Lastly we must install Superuser, and I did this from the android market so I knew its the latest version, its simple to get, less command input etc.
Now you have root! I hope this was simple enough to follow, I have not really written a guide before but from lots of searching I just could not find a solution for my Nexus One 2.2.1 FRG83D, especially any guide that uses psneuter.
Anyway, glad to contribute

I believe this is due to a change in the kernel as it is upgraded into gingerbread, the input/output controls have changed, leaving psneuter out of date with the current kernel.
However if an exploit is found with the kernel used in 2.3.3, you can use it in place of psneuter with the above method.
Hi.
I've tried many times to root my LG2X with Z4root, UniversalAndRoot, Visionary and SuperOneClick since I've bought it but it failed each time.
I've seen the [Root] topic in the developpement thread but I can't post there (less than 10 posts...) but I want to help someone to root his/her mobile.
I've searched a long time a good way to do so without SuperOneClick (which doesn't respond with Windows Seven or Ubuntu 11.04) but there is none.
There we go...
Disclaimer : I can't be responsible if you break your phone, cancel your warranty or launch your LG2X on the wall in rage.
If you want, there is already SuperOneClick which run smoothly for many geeks : LG2X SuperOneClick Forum and SuperOneClick Forum
My HTC Magic had been rooted with the command line and I've tried myself to do so with every bit of informations and tips I could find on Internet.
I recommand to test the SuperOneClick method and if it fails, come test this with a Linux terminal (psneuter, su-v2, busybox and the SuperUser.apk can be found in the SuperOneClick archive) :
Code:
adb push psneuter /data/local/tmp
adb push su-v2 /data/local/tmp
adb push busybox /data/local/tmp
adb shell
$ busybox chmod +x /data/local/tmp/psneuter
$ /data/local/tmp/psneuter
adb remount
adb shell
# busybox mv /data/local/tmp/su-v2 /system/xbin/su
# busybox chmod 6755 /system/xbin/su
# busybox chown 0.0 /system/xbin/su
# busybox cp /system/xbin/su /system/bin/su
# busybox chown 0.2000 /system/bin/su
# busybox cp /data/local/tmp/busybox /system/xbin
# busybox chmod 0755 /system/xbin/busybox
# busybox chown 0.2000 /system/xbin/busybox
# exit
adb install Superuser.apk
adb reboot
And... Normally you have permanent root on your LG2X.
You can check the files permissions with
Code:
ls -l /system/xbin/su /system/bin/su
-rwsr-sr-x root root 26264 2011-04-23 20:07 su
-rwsr-sr-x root shell 26264 2011-04-23 23:20 su
It seems that /system/xbin/su isn't necessary at all. The su command which gave you the root is the one in /system/bin/. And I had some problems with /system/xbin, I've deleted the folder (with rm /system/xbin or mv /system/xbin /dev/null, I can't recall) and applied mkdir on it again.
If this can be of help, I'll update this later.
thanks for the detailed instructions, but super one click definitely works with win7 (64bit too) as long as you have the right drivers installed
Thanks but with Windows Seven 64 bits, Linux ou Windows Seven 32 bits with Virtualbox I end up with "SuperOneClick doesn't respond" or stuck on with "chmod psneuter" (with the drivers properly installed).
It's only an alternative solution if SuperOneClick doesn't run properly for another guy.
Thanks a lot for that tips.
The problem I have now is that su isn't persistant.
When I use
$ su
It hangs up few seconds... and says "Permission denied"
I've used su-v2
Here are the su permission :
-rwsr-sr-x root shell 26324 2011-02-13 14:43 su
Is there a more up-to-date su, that will maybe fix the problem ?
Thanks.
EDIT :
Ok.
The wait time seems to come from SuperUser, I've removed it.
Now I have directly the "permission denied", and "stat failed with 2: No such file or directory" in the logcat.
Maybe that can help.

It didn't for me (after installing nightly 51)
With the step-by-step instructions I get "Failed to set prot mask (inappropriate ioctl for device)" when trying to execute psneuter.
Hi.
Sorry for the wait.
Have you resolved your problem with your rooting?
I FINALY FOUND MY PROBLEM
I have two binaries one in /system/xbin/su and the other in /system/bin/su
#ls -l /system/*/su gives me this:
-rwxrwxr- system sdcard_rw 380532 2013-05-22 17:13 su
-rwsr-xr-x root root 22236 2013-05-22 17:13 su
#chmod 06775 /system/bin/su gives me this:
unable to chmod /system/bin/su: readonly filesystem
#echo $PATH gives me this
/system/bin/su: /system/Xbin/su
so what should i do next?
is it possible to swap the path variables
i mean to make "echo $path give /system/Xbin/su:/system/bin/su"

Switch to SuperSU!
I have an un-rooted device, with Android 5.0 system, and the core is ARM Coretex A53.
I happen to found "adb root" works, that means I can play as root through ADB shell.
I successfully deleted a trash apk, renowned "kingroot", from my system.
Then, I try to manually update su and SuperSu file, through the bellowing commands:
# mount -o rw,remount /system
# cp /sdcard/mrw/su /system/xbin/su
# cp /sdcard/mrw/su /system/bin/su
# pm install /sdcard/mrw/superuser.apk
(I'm using a 2.46 SuperSu version, which should be OK for Android 5.0 system)
But it fails. The SuperSu told me " su binary not installed".
My questions:
1. Is this a feasible way to update Su and SuperSu, and get root access?
2. There's a bunch of architect, I tried both "arm" and "arm64", but none of the su binary can work. Which architect shall I choose, when I'm running on a ARM Coretex A53 core? ( I know it is a 64bit core)
Thanks a lot, and Best Regards,
towenyu
Did you get this device secondhand? Also what device is it, since many have their own root method because of OEM crap.
That said, you only need su in one location, either /system/xbin/su or /system/bin/su (I typically see it in /system/xbin/su). I'm not sure what happens if it's in both, but it's just wasted space.
You can try these commands through adb root; since you already were able to get su onto your device, it may be just a matter of ownership and permissions:
Code:
# mount -o rw,remount /system
# chmod 755 /system/xbin/su
# chown root:root /system/xbin/su
# mount -o ro,remount /system
chown 755 sets the permissions to rwxr-xr-x (user gets read/write/execute, group/other gets read/execute). Execute is the important bit here, since otherwise the su binary can't do its job. After those commands, try SuperSU again and see if it works (you might need a reboot, because of how Android 5.0+ handles changes to /system) The last mount -o ro command just changes /system back to read-only, to prevent accidental changes to other parts.
Successfully rooted!
Not that simple, but basically follow the update-binary script already inside supersu package.
Only need to made slight modification due to my system won't support "unzip"
Now that you're successfully rooted, go install Busybox, that'll give you a lot of Linux commands Android doesn't have by default, including unzip.

Thanks for your advice! I will try it.
But don't there's already a Busybox in android system? I guess what I need to do is find somewhere a more powerful busybox binary -- or build it by my own, but that may be not so easy for me.
Android has some basic Linux commands support, but I don't think it has Busybox (if you have a custom ROM you may have some additional commands, but since you said unrooted I don't think it was installed.
This is one of the most popular installers for Busybox: https://play.google.com/store/apps/details?id=stericson.busybox
I've used it since I first rooted with Android 2.2 and haven't had any issues with it (save for lack of vim, since stock Android doesn't have the correct libraries for it)
rooting my htc m9 running marshmallow
Hi, I'm totally blind, and twrp isn't an option for me since it doesn't have a built in screen reader. I would like to install supersu to system, would some one kindly help me in telling me what files to put where. I think the m9 is arm64, but besides su and supersu.apk, I think there's installrecovery.ssh and some other files that have to go in, so please help some one

Hi guys ,
it is possible to run manualy via adb shell update-binary file from META-INF supersu folder for install it ? (means before unpacked folder supersu is copied to ex. /tmp)
I'm asking bcose no custom recovery and no root on my device yet.
Thx

Thank You - I will check and give feedback
Can I somehow just copy su and supersu files to phone (stock ROM) with full root shell to get root? Unfortunately bootloader is locked and only root shell is available.

Of course not. If it were that easy rooting would be a non-issue for devices with a locked bootloader.
