Looking at several ROM's for the Desire, I notice that they put the busybox binary in /system/xbin rather than in /system/bin. Also they have links to toolbox in /system/bin for a lot of commands that also exist in busybox, and with /system/bin before /system/xbin in the $PATH will result in getting to the toolbox version, rather than the busybox version of a command. Especially commands like df and ifconfig have a very bad/limited output compared to the busybox versions.
(having to type "busybox df" or "/system/xbin/df" rather then just "df" irritates me)
Are there any special reason for doing it that way, ex are there parts of the android os, that needs to get to the toolbox version of commands to function correctly?
Just thought I wanted to ask, before testing this out.
Also are there a problem in removing /system/bin/sh, and replace it with a link to /system/bin/bash?
Ok, i know there is plenty of info about rooting various devices out there, however there i seem to locate anywhere that has an guide to actually rooting an Android system.
I understand to gain root access you must have a version of su that is compatible with your Kenel. I build an -eng build of AOSP and this includes a version of su into the system ( /system/xbin/su) with the following permissions.
Code:
-rwsr-sr-x root root 60112 2011-12-06 11:56 su
Its my understanding that each app in the Android system is essentially a individual user of the Linux system so i thought that all i would have to is grant the correct permissions for su so that any user can execute it.
Code:
chmod 755 su
-rwxr-xr-x root root 60112 2011-12-06 11:56 su
This does not seem to be the case, i have done this though when i try to su (from Terminal Emulator) i get this
Code:
$su
su: UID 10027 not allowed to su
$
Can anyone let me know what i am missing to allow root access for my applications?
Ok, so it is the version of su that is bad.
If you want to root any device get the correct version of su from here and include into your builds.
OK, I'm running into difficulties with this phone..
..It arrive pre-rooted, I installed Titanium Backup and removed iReader.
In the Play store I noticed that SuperUser and Google Keyboard needing updating but when I tried to do so all I got was "Error Installing - Package file was not signed correctly" which I assume has something to do with a slightly different version of the program initially installed?
Then I went into SuperUser itself, clicked on the spanner icon, scrolled down and tapped on the check for updates button..
..indeed it found an update and proceeded to update in a similar style terminal box.
However.. according to Titanium I no longer have root access, I quickly downloaded Root Checker Basic which also confirmed this.. bugger I thought.
Moving onwards, I just downloaded SRS Root from srsroot.com. Tried rooting and it exited out saying I already had root access.. hmmm, so then I removed root access, the phone rebooted and then I re-applied the root.
Although I am still suffering from not having proper root access :crying:
Please help me to get full root access back again, thanks in advance. :angel:

I still have Root Explorer on the phone and seem to be able to navigate through the normally hidden directories.
Suggestions please!
To my surprise, I bit the bullet today and reset my phone to stock defaults..
..unfortunately even this still did not fix the incomplete root
Please help!
EDIT : I've been tinkering again.. Here's what I understand (and what I've done)
System\bin\ - Kinda not the most important place to store a file relating to an installed .apk's
System\xbin\ - The more important place (kinda like the System32 directory) relaing to installed .apk's
System\app\ - The directory where the .apk file's themselves live (kinda like Program Files\xxx Application)
Well I noticed I had an .apk in apps called root_Superuser.apk and this was present even after un-rooting my phone.
I removed this file, using these commands :
adb remount
adb pull /system/app/root_Superuser.apk
Seemingly this didn't remove the file, so then I tried :
adb remount
abd shell rm -f /system/app/root_Superuser.apk
After a quick reboot this had indeed removed Superuser, then I reused the SRS Tool to re-root.
Then I read that SU 3.0.2 was a safer bet.. (although it was a post from 2011 - attached)
So I downloaded that and proceeded to push the superuser.apk and su files into their correct places (as below)
adb remount
adb push superuser.apk /system/app/
adb push su /system/xbin/
adb push su /system/bin/
After the files were correctly in place I needed to set the correct file permissions, I did this as follows :
abd shell
[email protected]:/ # CHMOD 644 /system/app/superuser.apk
[email protected]:/ # CHMOD 777 /system/xbin/su
[email protected]:/ # CHMOD 777 /system/bin/su
Finally I realised I had given /xbin/su the incorrect permissions so ammended them to :
abd shell
[email protected]:/ # CHMOD 4755 /system/xbin/su
[email protected]:/ # CHMOD 4755 /system/bin/su
The reason why I am writing exactly what I did is so I myself don't forget anything and also to show others how to do stuff should I be doing it correctly!? I wasn't sure if the su needed to go into xbin or bin so I put it into both directories and thus I can remove which ever one is incorrect once I get a reply from somebody!
Here's my current log from Root Checker Pro - I shall not be doing anything else without further assistance.

Great to see the Root Checker apps being used! Given you posted a link back to this thread in the Root Checker thread I'm posting my reply here.
The route I usually take and recommend, which does all of those steps you've performed, such as copying files and setting the correct permissions, is to load an "official" .zip file from the custom recovery.
If you have a custom recovery, I'd recommend loading SuperSU.zip, which has worked very well for me on my devices: http://forum.xda-developers.com/showthread.php?t=1538053
From the XDA post, there is a link to the .zip file that can be downloaded and loaded in the custom recovery: http://download.chainfire.eu/supersu
If you don't have a custom recovery, I think most of the steps you've taken are correct, but based on the Root Checker Pro output I'd be concerned that the Superuser.apk file you installed and the su binary aren't communicating and might be out of sync. This can be caused by many reasons but the solution is to make sure you installed a matching .apk and su binary.
Hope that helps and good luck!

Thanks for your reply JoeyKrim, unfortunately I don't think a custom recovery is available for this phone at present? I've had SuperSu on my device and to be honest not a great deal worked using it. I've also had both CWM / TWRP installed on the phone and both of them cannot find a suitable ROM to implement. I guess because of the phone being fairly new and a knock off doesn't exactly help me! :cyclops:
I will re-root my device and if that isn't successful manually try to match both superuser.apk and su binary with yet another version of superuser!
EDIT :
Here's what I've tried this morning (unfortunately now I have ran out of time and must get ready for college)
adb remount
adb push Superuser.apk /system/app/
adb push su /system/xbin/
adb push su /system/bin/
adb shell
[email protected]:/ # CHMOD 644 /system/app/Superuser.apk
[email protected]:/ # CHMOD 4755 /system/xbin/su
[email protected]:/ # CHMOD 4755 /system/bin/su
Superuser available to download from http://hosted.androidsu.com/superuser/
Using: su-3.0.1-d-signed.rar I get Superuser v3.0.1 (36), Su binary vnull (legacy)
su-3.0.1-efgh-signed.zip I get Superuser v3.0.1 (36), Su binary vnull (legacy)
Unsure of differences between d & efgh versions? Moved onto next version..
su-3.0.2-efgh-signed.zip I get Superuser v3.0.2 (37), Su binary vnull (legacy)
Renamed ([email protected]:/ # mv Superuser.apk root_Superuser.apk) seemingly no difference?
I was wondering if root allowed apps were renamed as root_appName.apk - I've left the file
name as this (i.e. Superuser.apk is NOT in my system/app/ directory and yet Superuser still
runs fine???)
Superuser-3.0.6-efgh-signed (Only binary updated) v3.0.2 (37), Su binary vnull (legacy)
su-bin-3.0.3.2-efghi-signed.zip Superuser v3.0.2 (37), Su binary vnull (legacy)
Isn't Su binary 3.0.3.2 the more up to date binary??? According my my Superuser's self update
it is?
Trying this release? - Also copied Superuser.apk to root_Superuser.apk as well this time..
Superuser-3.1-arm-signed Unable to check the versions.. different menu
Additionally myt Root Explorer (root_Root explorer.apk) now cannot gain root access which
is the first time this has EVERY occured
Superuser-3.1.1-x86-signed Unable to check the versions.. different menu
OK, so I know for sure that 3.1 is a more recent version of Superuser than I have ever had on
my phone, and of course root explorer doesn't now work, so trying an older version..
Superuser-3.0.7-efghi-signed.zip Superuser v3.0.7(41), Su binary v3.1
Again.. Root explorer no longer working.. tried deleting root_Superuser.apk
(adb shell rm -f /system/app/root_Superuser.apk)
Hasn't seemed to do anything different.. Removing all SuperUser files, ran out of time to
experiment with. Annoyed that now even my Root Explorer isn't working, I seem to be going
backwards and not forwards!!
After un-rooting (using SRSRoot) I once again have access to my Root Explorer??? Weird.

can anyone help me out with an
adb bat script that will check weather android is rooted
root files are located
superSU -- /system/app
su binary -- /system/xbin symlinked to /system/bin
i can find functions but nothing that is adb bat script.
any help would he appriciated.
The apps busybox x and busybox X+ don't include an option to uninstall them, so in case you have problems with the installed binaries you find yourself helpless and with issues.
Well, there's a workaround: uninstall buxybox x or X+. Then install BusyBox or BusyBox Pro from stericson, smart install it, and then uninstall with the option provided for that. Now you have your system clean back more or less. Probably there remains some binary lost in the system, but for the most part it will remain clean.
There's another way to do if from command line:
Code:
su
mount -o remount rw /system
cd /system/xbin
rm busybox
